The University of Arizona is committed to ensuring that every student integrates and applies learning via internships, jobs, research and other opportunities relevant to the real world. This is the third in a five-part UANews series detailing industry-related experiences UA students have completed.
Justin Sayers with his family at the UA commencement ceremony in May 2014.
Having earned his bachelor's degree in journalism from the UA in May, Justin Sayers spent part of his summer serving as a sports copy editor with the Hartford Courant, a newspaper in Connecticut.
While at the Courant, Sayers was responsible for editing sports stories for accuracy, grammar and style. In the deadline-prone environment, Sayers said he had to "adapt to the fast pace of a real-life newsroom. I've been able to learn a lot about copy editing, which has actually helped me become a better writer and better journalist."
Sayers returns to the UA this fall to begin the master's degree program in journalism, and his long-term professional plan is to work for a newspaper as a reporter. He offered insights about his summer experience.
Q: How did you land your summer internship?
Sayers: I got my internship for the summer through the UA's School of Journalism. When I was a junior, one of the representatives from the Dow Jones News Fund came to talk to my class about applying to the internship the following year.
Q: What was it about the position that captured your interest?
Sayers: I was interested in the internship because I've always had an interest in sports journalism, but never had the chance to do hands-on work in the field. I've already had a lot of experience with writing and reporting, so editing seemed like something I wanted to try. Luckily for me, I was accepted and was able to make myself more well-rounded this summer.
Q: How do you envision that your summer internship will help you in the future?
Sayers: I definitely think that this internship helped me both professionally and academically. I feel that I was able to gain a leg up on my peers by taking part in a unique opportunity. I feel the experiential learning prepared me for finding a job because it gave me a good sense of the industry I'm going into. And I decided to pursue a master's degree in journalism because I felt that one extra year for a second degree was an opportunity I could not pass up. My sister spent five years after graduating from college with a history degree working to become a dietitian, so she persuaded me when she heard that I could get a second degree that quickly. Also, anything to get me a leg up on my peers in the job hunt is a plus.
Q: What were some of the standout moments for you?
Sayers: The moments that stood out were the positive reinforcement that I received from my superiors. They let me know when I made mistakes, but did it in a constructive way, making sure that I learned from them. Also, I think the fact that everybody seemed upset when I left showed that I was able to assimilate myself into the newsroom during my short time there.
Q: What advice would you provide to other students?
Sayers: I definitely think that internships are the best way for students to prepare themselves for going out into the real world. Classes are important, but you can only talk about something so much without actually doing it. Being able to learn while also gaining experience is an opportunity that students should never pass up. It also allows you a little more freedom than jumping into a job you know nothing about right after college.Categories: Teaching and StudentsThis is a Wildcat Corner feature: Images: Tags: StudentsStudent LifeEducationOutreachByline: University RelationsEditor: dougcarrollInclude in UANow: 0Date of Publication: Wednesday, September 17, 2014Medium Summary: UA journalism student Justin Sayers spent most of his summer working as a sports copy editor.

The University of Arizona is committed to ensuring that every student integrates and applies learning via internships, jobs, research and other opportunities relevant to the real world. This is the second in a five-part UANews series detailing industry-related experiences UA students have completed.
Chelsea Hemphill, a UA journalism senior, served as a FOX 5 intern in Washington, D.C., working for the network covering news for the D.C. area and also the Maryland and Virginia region.
Hemphill was tasked with a broad range of responsibilities, including taking viewer calls, queuing news tips for the news desk, finding potential news stories and conducting interviews in the field.
Q: What was it about the position that captured your interest?
A: Working as an intern at FOX 5 was a dream come true because I was able to get hands-on experience going out in the field and I was able to work alongside reporters, which is a special treat. They kept it completely honest about how the news industry is. There was an ongoing joke almost every employee would say: "FOX is where you go to die." I first thought this was an insult, but it was actually a term of endearment because people who work for FOX usually stay there until they retire. They do it for all the right reasons, especially because it is a top-20 market. I also was excited for the challenge to show my supervisors that I could be of assistance to them.
Q: What did you learn during your experience?
A: This was an interesting job because I never knew how essential the viewer was in finding original stories to cover. I also would call to schedule interviews for future stories, go out in the field to get interviews, help assist photo shoots and help escort guest appearances. Then, above all else, it was my duty to get good practice working on standups and putting together packages. Also, the main thing I learned was that anchors and reporters go with the flow. They never know when some aspect of the show is going to malfunction. And because it is all live, they really are winging it almost every time they go on air.
Q: How do you envision that your summer internship will help you, academically and professionally?
A: As an intern, it's hard to come into the newsroom without a set plan of what you would like to accomplish. But if you show your determination early on, the news desk editor and reporters will give you stories to help them with. And that's where the real fun begins. This internship has definitely prepared me for my broadcast journalism classes. What I was taught at the station are some of the things I will be learning this next semester. On a professional level, it helps with networking.Categories: Teaching and StudentsThis is a Wildcat Corner feature: Images: Tags: StudentsStudent LifeEducationResearchOutreachByline: University Relations - Communications |Editor: dougcarrollInclude in UANow: 0Date of Publication: Tuesday, September 16, 2014Medium Summary: UA journalism student Chelsea Hemphill spent her summer in Washington, D.C., learning the ins and outs of broadcast news with FOX 5.Feature on Front: NoShort Summary: Chelsea Hemphill served as a summer intern at Fox 5 News in Washington, D.C.
The meteorite impact that spelled doom for the dinosaurs 66 million years ago decimated the evergreens among the flowering plants to a much greater extent than their deciduous peers, according to a study led by UA researchers. The results are published in the journal PLoS Biology.
Applying biomechanical formulas to a treasure trove of thousands of fossilized leaves of angiosperms — flowering plants excluding conifers — the team was able to reconstruct the ecology of a diverse plant community thriving during a 2.2 million-year period spanning the cataclysmic impact event, believed to have wiped out more than half of plant species living at the time.
The researchers found evidence that after the event, fast-growing, deciduous angiosperms had replaced their slow-growing, evergreen peers to a large extent. Living examples of evergreen angiosperms, such as holly and ivy, tend to prefer shade, don't grow very fast and sport dark-colored leaves.
"When you look at forests around the world today, you don't see many forests dominated by evergreen flowering plants," said the study's lead author, Benjamin Blonder, who graduated last year from the lab of UA Professor Brian Enquist with a Ph.D. from the UA's Department of Ecology and Evolutionary Biology and is now the science coordinator at the UA SkySchool. "Instead, they are dominated by deciduous species, plants that lose their leaves at some point during the year."
The study provides much-needed evidence for how the extinction event unfolded in the plant communities at the time, Blonder said. While it was known that the plant species that existed before the impact were different from those that came after, data was sparse on whether the shift in plant assemblages was just a random phenomenon or a direct result of the event.
"If you think about a mass extinction caused by catastrophic event such as a meteorite impacting Earth, you might imagine all species are equally likely to die," Blonder said. "Survival of the fittest doesn't apply — the impact is like a reset button. The alternative hypothesis, however, is that some species had properties that enabled them to survive.
"Our study provides evidence of a dramatic shift from slow-growing plants to fast-growing species," he said. "This tells us that the extinction was not random, and the way in which a plant acquires resources predicts how it can respond to a major disturbance. And potentially this also tells us why we find that modern forests are generally deciduous and not evergreen."
Previously, other scientists found evidence of a dramatic drop in temperature caused by dust from the impact. Under the conditions of such an "impact winter," many plants would have struggled harvesting enough sunlight to maintain their metabolism and growth.
"The hypothesis is that the impact winter introduced a very variable climate," Blonder said. "That would have favored plants that grew quickly and could take advantage of changing conditions, such as deciduous plants."
Blonder, Enquist and their colleagues Dana Royer from Wesleyan University, Kirk Johnson from the Smithsonian National Museum of Natural History and Ian Miller from the Denver Museum of Nature and Science studied a total of about 1,000 fossilized plant leaves collected from a location in southern North Dakota, embedded in rock layers known as the Hell Creek Formation, in what at the time was a lowland floodplain crisscrossed by river channels. The collection consists of more than 10,000 identified plant fossils and is housed primarily at the Denver Museum of Nature and Science.
By analyzing leaves, which convert carbon dioxide from the atmosphere and water into nutrients for the plant, the study followed a new approach that enabled the researchers to predict how plant species used carbon and water, shedding light on the ecological strategies of plant communities long gone, hidden under sediments for many millions of years.
"We measured the mass of a given leaf in relation to its area, which tells us whether the leaf was a chunky, expensive one to make for the plant, or whether it was a more flimsy, cheap one," Blonder explained. "In other words, how much carbon the plant had invested in the leaf."
In addition to the leaves' mass-per-area ratio, Blonder and his coworkers measured the density of the leaves' vein networks.
"When you hold a leaf up to the light, you see a pattern of veins running through it," Blonder said. "That network determines how much water is moved through the leaf. If the density is high, the plant is able to transpire more water, and that means it can acquire carbon faster.
"By comparing the two parameters, we get an idea of resources invested versus resources returned, and that allows us to capture the ecological strategy of the plants we studied long after they went extinct."
Evergreen plants are more likely to invest in leaves that are costly to construct but are well-built and last a long time, Blonder explained, while the leaves of deciduous plants tend to be short-lived but offer high metabolic rates.
"There is a spectrum between fast- and slow-growing species," he said. "There is the 'live fast, die young' strategy and there is the 'slow but steady' strategy. You could compare it to financial strategies investing in stocks versus bonds."
The analyses revealed that while slow-growing evergreens dominated the plant assemblages before the extinction event, fast-growing flowering species had taken their places afterward.
The National Science Foundation awarded Blonder a graduate research fellowship to pursue this research. Additional funding was provided by the Geological Society of America.
Blonder said he was inspired to pursue the research project after seeing a lecture on paleobiology at the UA.
"I had a strong interest in how plants function based on their leaves, and I was fascinated to learn about applying those biomechanical principles to reconstruct ecological functions of the past," he said. "When you hold one of those leaves that is so exquisitely preserved in your hand knowing it's 66 million years old, it's a humbling feeling."Writer: Daniel StolteByline: Daniel StolteByline Affiliation: University Relations - CommunicationsExtra Info:

The Associated Students of the University of Arizona, the student governing body, and Arizona Public Media, the local PBS station based at the UA, are co-hosting a Sept. 21 public forum with candidates in Arizona's November gubernatorial election.
Candidates from four political parties — Doug Ducey for the Republican Party, Fred DuVal for the Democratic Party, Barry Hess for the Arizona Libertarian Party and JL Mealer for the Americans Elect — have been invited to participate in the 90-minute forum, which is free and open to the public (tickets are required). The forum will begin at 6 p.m. and end at 7:30.
"It was important for ASUA to partner with Arizona Public Media on this forum to ensure that the outreach got to all corners of Arizona," said Issac Ortega, president of ASUA, the representative student voice of more than 41,000 UA students.
Moderators will be Lorraine Rivera, host of AZPM's "Arizona Week" and Joey Fisher, editor-in-chief of the Arizona Daily Wildcat. The event will be captioned.
UA students and the public are encouraged to submit questions for the candidates using #OurVoiceOurVote or at firstname.lastname@example.org.
"We want to provide a high-quality event where candidates would be asked about questions important to both students of the University of Arizona and the Tucson community," Ortega said.
"The governor affects the lives of all the students at the University of Arizona and across the state, so I really hope that both students and the public gain some perspective on the solutions the candidates for Arizona's next governor have to offer," he said. "Also, and more importantly, I hope that the community will take to the polls and weigh in on the next leader of our state."

Unexpected job loss is one of the most stressful life events a person can experience, and it affects much more than one's pocketbook. It might also lead to weight gain, research suggests.
Studies have indicated that unemployed people tend to have a higher body mass index, on average, than those who are employed. A new University of Arizona study will look at why that might be.
Patricia Haynes, assistant professor of psychiatry in the UA College of Medicine, has been awarded a five-year, $3.1 million grant from the National Heart, Lung and Blood Institute, part of the National Institutes of Health, to study the link between job loss and weight gain. She will look specifically at how post-job-loss changes in sleep and social rhythm — a person's daily routine — might affect weight.
"The idea is that unemployed individuals have had a disruption of their daily routine, which is like losing an anchor in the time structure of their day," Haynes said. "Their social rhythm becomes disrupted, which may then impact their biological rhythms and sleep, and increase the propensity towards excessive caloric consumption."
While existing data suggests that insufficient sleep can lead to changes in appetite and satiety hormones, few studies have examined that relationship in a real-world setting, Haynes said.
Haynes developed the idea for the study after listening to National Public Radio. A story about unemployment and the recession was immediately followed by a separate, unrelated story about the country's growing obesity problem. It occurred to Haynes that the two issues might be connected.
The Centers for Disease Control and Prevention estimates about 65 percent of Americans are now overweight or obese. Research suggests that the obesity rate increased during the recession, but the cause for the increase is not entirely clear. Haynes believes that poor sleep quality and disruptions to people's daily routines after job loss could be largely to blame.
Haynes and her research team will follow 250 recently unemployed people over an 18-month period, using smartphones to capture information about participants' daily behaviors in real time. For example, participants might be prompted, via a message on the phone, to report on how they slept the night before, what kind of exercise they did that day or what activity they are doing at any given moment. Select participants also will be asked to take and submit photos of the food they eat. All participants will undergo weight and nutrition assessments in the lab.
Haynes is partnering with the Arizona Department of Economic Security's Unemployment Insurance Administration to identify potential study participants — people who involuntarily lost their jobs within six months of enrolling in the study.
She expects that some study participants will be more vulnerable to weight gain than others. Those hardest hit by the job loss might engage in more sedentary activities, such as watching TV or eating unhealthy foods, she said. At the same time, there may be a subset of more resilient people who see job loss as an opportunity to devote more time to exercising or improving their health.
Haynes also is interested in exploring the effects of re-employment — that is, how a person's sleep, daily routine and weight is impacted if he or she finds new employment during the course of the study.
Haynes hopes that the results of her study will inform health and weight interventions and programs for the recently unemployed.
"Sleep and social rhythms are highly amenable to change by behavioral intervention," she said. "Therefore, these data will help us determine whether typical weight-loss programs might be enhanced by also targeting sleep and social rhythms."
Dr. Ole Thienhaus, professor and head of the Department of Psychiatry in the UA College of Medicine, said the study could have a broad impact.
"Unemployment, chronic sleep restriction and obesity are highly prevalent social and public health issues," he said. "I anticipate that the results of this study will be of high relevance to a large segment of the U.S. population."
Haynes is a behavioral sleep medicine specialist and clinical psychologist who studies insomnia, stress and how people's daily behaviors affect sleep. As director of the UA's Stress and Trauma Recovery Clinic, her research includes studies looking at sleep and post-traumatic stress disorder.
Her collaborators on the unemployment study include Emily A. Butler, associate professor of family studies and human development in the UA College of Agriculture and Life Sciences; Duane Sherrill, professor of biostatistics in the UA's Mel and Enid Zuckerman College of Public Health; Graciela Silva, assistant clinical professor of nursing in the UA College of Nursing; Cynthia Thomson, UA professor of public health and director of the Canyon Ranch Center for Prevention and Health Promotion; Dr. Stuart F. Quan, professor emeritus of medicine, pulmonary and critical care medicine in the UA College of Medicine and the Gerald E. McGinnis Professor of Sleep Medicine at Harvard Medical School; George W.

After spending five months in tumultuous Islamabad, Adele Barker says the experience has changed her outlook on education, her work and life.
Barker is a professor in the University of Arizona Department of Russian and Slavic Studies, and was selected as a Fulbright Scholar to teach and write in Islamabad, the capital city of Pakistan. Fulbright Scholarships allow scholars to travel to other countries for a variety of educational activities such as university lecturing, research, graduate studies and teaching.
Barker was one of only two Fulbright Scholars to work in Pakistan.
Pakistan has seen increasingly violent rallies and protests against the country's government, based in Islamabad. For this reason, Barker was kept under strict security restrictions during her entire stay.
"The security around me was very, very tight," Barker said. "But it was also something I knew about before I went there. In my case, because I write, I simply adjusted my vision downwards to accommodate the smaller world in which I was placed."
During her time abroad, she taught graduate students at Fatima Jinnah Women University, located in Rawalpindi, approximately a 40-minute drive from Islamabad. She taught courses on contemporary American women writers and 19th-century Russian literature, primarily focusing on Leo Tolstoy's classic novel "Anna Karenina."
"I tell you, if there's any way to break down barriers, it's by sitting in a room talking about a text," Barker said. "I didn't realize it, but I wasn't winning any popularity contests when I arrived. All but one of my students had never met an American, and had never been taught by an American. Their opinion of me was initially formed by many of the U.S. government's missteps in Pakistan. Fortunately, our time together in the classroom created a space where I became more than the representative of U.S. policy."
Barker said that she never felt her safety was threatened, although she witnessed public rallies, and the Pakistani military became a pervasive presence on the streets of Islamabad during her time there.
"Essentially, everyone in a city of any size in Pakistan is moving about with the Pakistani military on every street corner and road," she said. "It is a country in which anyone becomes a target because of the random nature of the violence. Islamabad in particular saw some very tough times in 2008, the bombing of the Marriott Hotel being just one example, and as a result businesses, government buildings and even private residences are heavily guarded, indeed sandbagged today. The memory of those times still reverberates over there today."
Barker spent much of her free time learning the local language of Urdu, reading contemporary Pakistani novels, visiting her local market and learning to cook the local cuisine, including her new favorite dish called saag, or Pakistani spinach.
She received permission for the Fulbright Commission to take evening walks with her neighbor in one of the large parks in Islamabad.
"Teach me Pakistan,” she told him. "And he did, six kilometers a night."
Because she wasn't allowed to travel far, her students became her window to Pakistan.
"They were my key to the culture," Barker said. "They taught me. I had never lived in an Islamic society. I was fascinated. ... I remember during my last week there, it was Ramadan. I was cooking iftar – that's the meal you cook to break the fast. As I was serving it, I realized everybody in this country was having the exact same meal at the exact same time. I found that notion very compelling. For me, it was the antidote to much commonly voiced opinion that sees the country as descending irrevocably into chaos."
Barker, who is also a writer, is working on a writing project about her experience, and hopes to return to Pakistan soon – ideally with more freedom to move about the culture.
"I was in the middle of my writing project and I had to come back," she said. "My work over there isn't done. My (Pakistani) colleagues and friends said 'Don't give up writing, you must write about this country, because we would like you to correct the impression that many Americans have of who were are.' I knew I wanted to do this."
While she readjusts to American culture and starts a new academic year at the UA, she hopes her students appreciate the opportunity they have to receive an education.
"I can't claim to have any scholarly expertise on Pakistan, but what I have is the unique experience – which I hope to repeat – of being able to teach in the Pakistani classroom and to teach young Pakistani women, for whom there is really a high risk in certain parts of that country if they want to get an education," she said.
"I think the greatest thing I bring back from my students is the great motivation from every young person I met to get an education, to get it right and really do something with it. When you live on the edge, as they do over there ... you take nothing for granted."Editor: dougcarrollByline: Amanda BallardByline Affiliation: University Relations - CommunicationsExtra Info:

Reflecting on their time as undergraduate students, three University of Arizona Regents' Professors say that collaborative work is underrated, humanities and history courses are indeed valuable, and mistakes can be a great teacher.
That’s just some of the wisdom imparted by Diana Liverman, Regents' Professor of Geography and Development and co-director of the UA Institute of the Environment, who is currently on sabbatical; Toni Massaro, Dean Emerita of the UA James E. Rogers College of Law; and Pierre Meystre, a Regents' Professor of Physics and Optical Sciences and director of the UA Biosphere 2 Institute.
Q: What tips would you share with today's students to help them succeed in the academic environment?
Liverman (left): Try to turn up to most of your classes and spend some of the time listening to what's being said instead of taking notes on your computer or checking social media. In smaller classes, ask questions, and never begin your comment with “This is probably a stupid question but ...” Remember, there really are no stupid questions! Go to exam study sessions and form study groups.
Massaro (right): Make your academic ends the first priority. A lot of things are available in college that are exciting and important to the experience: making new friends, exploring autonomy, balancing school and social life. But the classroom and academic work should be your first priorities in order to make the most of the opportunity to grow intellectually.
Meystre: Embrace your ignorance. Learn to be comfortable with not knowing the answer, but then don't stop until you have it figured out. Don't be afraid to ask questions, even simple questions. Questions that may seem simple can lead to profound answers. And chances are that others don't know, either, and will be happy that somebody asks — or they will know the answer, and then they'll be able to help you. Also, be open to unexpected opportunities and challenges.
Q: What do you wish you had known when you were a freshman?
Liverman: That so many opportunities would open up for me as an environmentalist and woman during my lifetime. When I was a freshman, there were no “green” careers, and it was tough for a woman to succeed in the environmental arena. Second, that working in a group — rather than competing — can help you be a success. And third, that I didn't have to find a husband my first year at college (that's what my grandmother thought I should be focusing on). It is much more fun to look around, travel the world and find someone later.
Meystre (left): That one should not be afraid to make mistakes. Being overly cautious can be paralyzing, and one often learns more from failures than from success. And for a curious mind, what can possibly be more boring and uninteresting than having things run just as expected?
Q: What would you have done differently?
Liverman: I would do study abroad. I would do internships and/or volunteer for local environmental or other organizations. I would take more science.
Meystre: I don’t think much about that. I don't find it particularly useful to obsess about "missed opportunities." We have just one ride and may as well enjoy it.
Q: What turned out to be your best move?
Liverman: Helping a visiting professor with her research one summer. She then invited me to take a master’s degree with her in Canada.
Massaro: Taking Bergen Evans' world literature course. A Northwestern classic, and the best course I took in college. And then choosing law school for my graduate work.
Meystre: Picking a great field of study. Physics is extraordinarily beautiful and exciting. It challenges you at every turn and always hits you with new surprises, with profound questions ranging from the origin of the universe to the nature of reality, and with practical applications that can have a significant societal impact.
Q: What was your most career-determining stroke of luck or serendipitous event?
Liverman: Getting an internship at the National Center for Atmospheric Research in Boulder, Colo., and persuading climate scientist Stephen Schneider to supervise me. He set me on my path to becoming a researcher, mentored me for many subsequent opportunities.
Massaro: A conversation with an undergraduate professor my senior year of college telling me "You ought to go to law school," even though she had been steering me to her own graduate/Ph.D. program the previous three years. Her shift helped me take the big leap professionally (and personally). And then, at the end of law school, two professors encouraged me to apply for a law-teaching job after my time in practice. I was extremely fortunate to have teachers who took such a keen interest in all of their students.
Meystre: There are too many to count. Most lucky perhaps was picking a specialization that was not very fashionable at the time but that turned out to become very hot, and also being at the right place at the right time.
Q: Anything else you’d like to share?
Liverman: You will make the most amazing friends in college who will see you through all the ups and downs of life. Look for ways to meet new people, not always like you, and it will change your life.
Massaro: Make the most of this moment, knock on your teachers' doors and enjoy your classmates. They can be your best teachers, too. Raise your hand. Be curious. Then "pay it forward" by helping others with their studies or volunteering in the community. There is no better way to learn than to teach others.
Meystre: Don't forget to have fun. If you don't, maybe you are not doing what you should be doing.
Diana Liverman's expertise and research interests focus on the human dimensions of environmental change, connecting earth and social sciences to understand challenges of drought and climate change, climate policy, climate change communication, food security, land use and international environmental governance. Liverman has advised a wide range of government committees, non-governmental organizations and businesses on climate issues. The first woman to serve in the position, Toni Massaro is also one of the longest-serving UA deans in recent history. Massaro, who holds the Milton O. Riepe Chair in Constitutional Law, has been with the college since 1989 and is an expert in civil procedure and constitutional law. And originally from Switzerland, Pierre Meystre, who joined the UA in 1986, has developed theory that has profoundly influenced all aspects of quantum optics, according to Nobel Prize winners in that field. He was named Regents' Professor in 2002.Categories: Teaching and StudentsThis is a Wildcat Corner feature: Images: Tags: FacultyResearchStudent LifeByline: Daniel Stolte, University Relations - Communications |UANow Image: Editor: La Monica Everett-HaynesInclude in UANow: yesDate of Publication: Wednesday, September 10, 2014Medium Summary: UANews asked three University of Arizona Regents' Professors about what they would do today to get the most out of their college experience if they were to be undergraduate students again.

Seeing is believing, but not seeing can be believing, too.
A University of Arizona study has found that objects in our visual field of which we are not consciously aware still may influence our decisions. The findings refute traditional ideas about visual perception and cognition, and they could shed light on why we sometimes make decisions – stepping into a street, choosing not to merge into a traffic lane – without really knowing why.
Laura Cacciamani, who recently earned her doctorate in psychology with a minor in neuroscience, has found supporting evidence. Her study, published online in the journal Attention, Perception and Psychophysics, shows that the brain’s subconscious processing has an impact on behavior and decision-making.
This seems to make evolutionary sense, Cacciamani said. Early humans would have required keen awareness of their surroundings on a subliminal level in order to survive.
"Your brain is always monitoring for meaning in the world, to be aware of your general surroundings and potential predators," said Cacciamani, lead author on the co-authored paper. "You can be focused on a task, but your brain is assessing the meaning of everything around you – even objects that you’re not consciously perceiving."
The study builds on the findings of earlier research by Jay Sanguinetti, who also was a doctoral candidate in the UA Department of Psychology. Both studies go against conventional wisdom.
"According to the traditional view, the brain accesses the meaning – or the memory – of an object after you perceive it," Cacciamani said. "Against this view, we have now shown that the meaning of an object can be accessed before conscious perception.
"We're showing that there's more interplay between memory and perception than previously has been assumed," she said.
Cacciamani asked participants in her study to classify nouns that appeared on a computer screen as naming a natural object or artificial object by pressing one of two buttons labeled “natural” or “artificial.” For example, the word “leaf” indicates an object found in nature, while “anchor” indicates a man-made or artificial object.
But before each word appeared on the screen, the computer flashed a black silhouette that – unknown to participants – had portions of natural or artificial objects suggested along the white outside regions (called the "ground" regions) of the image. Participants were not told to look for anything in the silhouettes, and they were flashed so quickly – 50 milliseconds – that it would have been difficult to notice the objects in the ground regions even if someone knew what to look for. Participants never were aware that the silhouette’s grounds suggested recognizable objects.
Cacciamani measured how well study participants performed at categorizing the words as natural or artificial by recording speed and accuracy.
"We found that participants performed better on the natural/artificial word task when that word followed a silhouette whose ground contained an object of the same rather than a different category," Cacciamani said.
This indicates that the brain accessed the meaning of the objects in the silhouette’s grounds even though study participants didn’t know the objects were there, she said.
"Every day our visual systems are bombarded with more information than we can consciously be aware of," Cacciamani said. "We're showing that your brain might still be accessing information without your conscious awareness, and that could influence your behavior."
Cacciamani's study was co-authored by Mary Peterson, Cacciamani' primary adviser and a UA professor of psychology and cognitive science as well as director of the UA's Cognitive Science Program, and by Sanguinetti and Andrew Mojica, recent graduates of the Department of Psychology's doctoral program.
After graduation, Cacciamani will take a position as a postdoctoral fellow at the Smith-Kettlewell Eye Research Institute in San Francisco. The study was funded by a National Science Foundation grant.Editor: La Monica Everett-HaynesWriter: Shelley LittinByline: Shelley LittinByline Affiliation: University Relations - CommunicationsHeader image: YesNo Image: Subheading: A UA study finds that objects in our visual environment needn’t be seen in order to impact decision making.

With a Nikon confocal microscope with heightened optical resolution, and using a high-magnification, 40X objective lens, Rachel Schafer captured the image that landed on the cover (right) of BioTechniques, an international journal.
"It is enjoyable to see my hard work come to fruition through this publication and be well-received within the research community," said Schafer, who is in the biomedical engineering program. "The publication and feedback received pave the way for cancer research studies using the model to be performed in the lab."
Schafer caught the image for an article she co-authored with researchers Hui Min Leung and Arthur F. Gmitro, both of the UA. The article, "Multi-modality imaging of a murine mammary window chamber for breast cancer research," was published in the July issue of BioTechniques.
The image, which was selected for the August edition, captures individual cancer cells and the network of small blood vessels from one location in a tumor, Schafer said.
"The image is one example of the multiple imaging technologies we applied to this unique cancer model," she said. "We aimed to expand the imaging capabilities applied to this type of cancer model and, in so doing, highlight the potential of the model for use in cancer studies."
The ability to combine multiple imaging capabilities enables researchers to gather information at different scales, aiding the analysis of tissues.
"The optical sectioning capability of confocal microscopes allowed a series of images to be acquired at sequential depths into the tissue," Schafer said. "These multiple slices through the tissue were combined to create the single maximum intensity projection image seen in the cover image."Categories: Science and TechnologyThis is a Wildcat Corner feature: Images: Tags: StudentsResearchEducationOutreachByline: University Relations - Communications |UANow Image: Editor: La Monica Everett-HaynesInclude in UANow: yesDate of Publication: Thursday, September 4, 2014Medium Summary: Rachel Schafer, a fifth-year doctoral candidate in the UA biomedical engineering program, has made it to the cover of BioTechniques, an international journal focused on the technical aspects of research in biotechnology.

Arizona Public Media's "Arizona Illustrated," a 30-minute weekly television and online magazine-style series, will resume this weekend after a hiatus, with a new format that builds on its history of engaging viewers with thought-provoking, diverse stories that reflect the southern Arizona community.
For more than 30 years, "Arizona Illustrated" has been AZPM's flagship original production on PBS 6 and online. Through the years, the program has delivered news and information about politics, the arts, history, science, nature and technology to the living rooms, laptops and smartphones of viewers throughout the region.
The program went on hiatus during the spring through the summer and will now repeat multiple times during the week instead of airing on Sundays only.
"AZPM's production staff has worked diligently over the summer to research, develop and produce stories for the relaunch of 'Arizona Illustrated,'" said John Booth, the executive producer of AZPM, an operating unit of the UA.
"Each episode will feature character-driven 'minidocumentaries' – carefully crafted to be informative, journalistically sound, and yet personal," Booth said about the new format.
The host will be 36-year veteran broadcast journalist Tom McNamara, who will invite viewers to discover untold stories that showcase creative storytelling with a special focus on the people who shape our community’s identity. The new format premieres Sunday at 6:30 p.m. on PBS 6.
The show is a "slice of life you won't find anywhere else," McNamara said.
Several documentaries, which will soon air on the show, are available to view online:
- "Growing Up Roosevelt," a storytelling narrative with Nina Roosevelt Gibson, the granddaughter of former U.S. President Franklin D. Roosevelt and former first lady Eleanor Roosevelt.
- "The New Keepers," habitat and groundwater conservation and protection efforts in the Tucson region.
- "Drummer Artt Frank: Giving a Rhythm to Greatness," about Frank's lifelong career and work with some of the world's most famous jazz musicians, including Billie Holiday, Charlie Parker and Chet Baker.
- "Buenos Aires National Wildlife Refuge," which explores the protected habitat, which has been reserved for threatened and endangered animals and plants.
- "Urban Bees," which features backyard honeybee enthusiasts.
McNamara, a member of the Tucson community since 1997, serves as the evening news anchor at KVOA-TV Channel 4. McNamara will continue his role as news anchor for the 5, 6 and 10 p.m. newscasts at KVOA while hosting "Arizona Illustrated."
"I am thrilled to host 'Arizona Illustrated,' and am grateful to KVOA for allowing me to jump on this opportunity," McNamara said. "This program returns me to my roots in local television."Editor: La Monica Everett-HaynesByline Affiliation: Arizona Public MediaExtra Info:

The OSIRIS-REx asteroid mission team invites the public to submit short statements and images about solar system exploration – today and in the future – to fly aboard the OSIRIS-REx spacecraft launching in 2016.
The Asteroid Time Capsule campaign asks people to think about what space exploration looks like today and what it might look like in the year 2023. They can share their predictions via Twitter or Instagram.
A digital collection of the top entries will travel to the asteroid Bennu aboard NASA's OSIRIS-REx spacecraft. Led by the University of Arizona, the robotic OSIRIS-REx mission is the first U.S. mission to carry samples from an asteroid back to Earth.
The selected entries will be etched into two "time capsules," each consisting of a one-square-inch silicon wafer. One wafer will be affixed to the spacecraft, the other will be attached to the sample return capsule, which will detach and deliver its cargo of asteroid material to Earth in 2023.
"Our progress in space exploration has been nothing short of amazing," said Dante Lauretta, OSIRIS-REx principal investigator and professor in the UA's Lunar and Planetary Lab and Department of Planetary Sciences. "I look forward to the public taking their best guess at what the next 10 years hold and then comparing their predictions with developments in 2023."
Posts can be about science, engineering, technology or other subjects related to space exploration today and in 2023. OSIRIS-REx will collect tweets and choose the top messages and images to send with the spacecraft.
"We're excited to see if we can predict how we will be operating in space a decade from now," said Ed Beshore, the mission's deputy principal investigator. "Here's a sample – '2014: We're building a spacecraft to go to an asteroid for a sample; 2023: We'll be using asteroids for fueling stations for expeditions.'"
OSIRIS-REx will study and map the 1,760-foot-wide asteroid Bennu for two-and-a-half years, then will collect a sample of surface material and head back to Earth. In 2023, after a journey of more than 3.9 billion miles – the equivalent of going around the earth 160,000 times – the OSIRIS-REx spacecraft will release the sample return capsule as it approaches Earth.
The capsule will enter Earth's atmosphere at about 28,000 mph, streaking across the western United States and landing in the Utah desert, returning as much as 4 pounds of asteroid material and one of the two "time capsules" to Earth. Upon arrival, mission managers will retrieve the digital content to check on the predictions. The other wafer, affixed to the OSIRIS-REx spacecraft, will continue to travel through deep space indefinitely.
"In 2023, when the OSIRIS-REx sample return capsule comes back to Earth with some of the oldest material found in solar system, we'll see where public perceptions of space exploration in 2014 were and where we thought we'd be in 2023," Lauretta said.
A few simple rules help guide members of the public in creating a time capsule entry:
- Think about what we are doing in solar system exploration in 2014 and what we might be doing in 2023.
- Tweet your statement with hashtag #AsteroidMission or tag OSIRIS-REx on Instagram with the hashtag #AsteroidMission to share your ideas as a graphic or photo.
OSIRIS-REx's sample of asteroid material will help with the investigation of planet formation and the origin of life and will provide insight into the future exploration of asteroids for resources and economic development. The data collected from the asteroid also will aid in the threat assessment of future asteroids that are headed toward Earth.
The Asteroid Time Capsule campaign complements "Messages to Bennu!," a public engagement campaign launched in January that invites people from around the world to submit their names to fly on the spacecraft.
Submissions for both campaigns will be accepted until Sept. 30.
"We have collected almost 350,000 names with the 'Messages to Bennu!' campaign," Beshore said. "Our goal is to collect 500,000 names by the end of September, but we'd like to shatter that goal."
"OSIRIS-REx has to take many years to perform a complex asteroid sample return," said Bruce Betts, director of science and technology for The Planetary Society, a public outreach partner on the mission. "A time capsule capitalizes on the long duration of the mission to engage the public in thinking about space exploration: Where are we now, and where will we be?"

Imagine breathtaking views of Earth from orbit, watching hurricanes churn a hundred miles below, then following the billowing plume of a volcanic eruption as it spreads out across the ocean before you plunge into the glowing veils of the aurora dancing toward you over the horizon.
You don't have to be an astronaut aboard the International Space Station to experience all this – all you need is a ticket to the University of Arizona's Flandrau Science Center and Planetarium, where a state-of-the-art digital projection system called Flandrau FullDome has been installed over the summer.
The FullDome projection system consists of two ultra high resolution digital projectors driven by powerful computers, a software capable of turning near real-time science data into images and a new audio system. The system uses two projectors linked to a powerful computer system that will digitally “stitch” the images together to deliver crisp detailed pictures that cover the whole planetarium dome and surround the audience.
"Our new projection system really transforms the planetarium experience," said Bill Plant, exhibits director at Flandrau Science Center. "Imagine an IMAX theater with a joystick, and you have a sense of what this awe-inspiring new planetarium technology can do."
Uniview, the system's software engine, provides access to a network of satellite imagery, updated daily, that Flandrau personnel can quickly integrate into a show to engage viewers with fascinating events occurring anywhere on the globe, Plant explained.
"For example, if there is a volcanic eruption somewhere, a forest fire or a hurricane, we can take our visitors on a visual journey right into the center of action and explain what's behind those phenomena."
Currently, visitors can immerse themselves into swirling weather patterns, fly over the surface of Mars, swoop through the ice crystals of Saturn’s rings, zoom out from our solar system to see our entire Milky Way galaxy in vivid detail, explore the majestic and colorful remains of a recent supernova, and travel to the edge of the known universe.
Eventually, the FullDome system will be able to turn virtually any scientific topic into a visual experience, from dinosaurs to microbes. For example, viewers will be able to embark on a journey into the human body and even explore the inner workings of cells. Shows about a wide variety of science topics have been produced and Flandrau will be bringing in new FullDome shows in the months ahead.
Flandrau is the first in the U.S. to install the new projection system, which is produced by Swedish company SCISS under the name Colorspace. The imagery dataset, called Digital Universe, was developed by the American Museum of Natural History’s Hayden Planetarium. It incorporates data from dozens of organizations worldwide to create the most complete and accurate 3-D atlas of the universe from the local solar neighborhood out to the edge of the observable Universe.
Flandrau, part of the UA College of Science, will also use the new system as a powerful teaching tool for UA students, allowing for a truly immersive learning experience. Thomas Fleming, an Astronomer and Senior Lecturer at the UA Steward Observatory and Department of Astronomy, already is using the FullDome system to teach astronomy to undergraduates this fall semester.
Since it opened in 1975, the Flandrau Science Center and Planetarium has been using a mechanical star projector, nicknamed "Hector Vector Star Projector," to give visitors a tour of the night skies.
"Hector was the state-of-the-art when he was installed, and he is a beautiful machine, but he can’t compete with today’s high-resolution digital technology," Plant said. "In recent years, both science and technology have advanced by leaps and bounds. We now have incredible images of our own planet Earth as it changes over time, and photos and data maps of other planets and other galaxies. New discoveries are being made every day, and now we can share those with our audiences in stunning ways."
FullDome is set to transform STEM education and outreach in the Tucson area, as the system can play any of the many shows produced for full dome systems on topics ranging from ocean life to neuroscience to the world of M.C. Escher. At the moment, Flandrau is screening the full dome shows "Magic Tree House: Space Mission" based on the popular children's book series, "Back to the Moon for Good" about the Google Lunar XPRIZE, and "IBEX," a documentary about NASA's Interstellar Boundary Explorer spacecraft.
"The experience will reach people of all ages and backgrounds, help them understand the marvels of science, and inspire the next generation of scientists," Plant said.
Flandrau Science Center, part of the UA College of Science, worked closely with the College and UA Bookstores to raise funds for the new system. Purchase and installation of the FullDome system was made possible entirely through the generous support of a number of donors to the UA College of Science.Writer: Daniel StolteByline: Daniel StolteByline Affiliation: University Relations - CommunicationsExtra Info:
The new Flandrau FullDome system will debut to the public on Friday, Sept. 5, with a kickoff event from 4 to 9 p.m. that will include live science demos, a raffle, and prizes.
On Sept. 6, Flandrau will host "International Observe the Moon Night" from 5:30 to 9:30 p.m. Organized by the Planetary Science Institute, admission to Flandrau will be free with lunar telescope viewing outside and moon-related activities inside the Science Center.

Using data taken by NASA's Spitzer Space Telescope, astronomers at the University of Arizona have spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of terrestrial planets.
A few months after scientists began tracking the star, called NGC 2547-ID8, it surged with a huge amount of fresh dust between August 2012 and January 2013.
"We think two big asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now smashing themselves into smithereens and slowly leaking away from the star," said Huan Meng, the study's lead author and a graduate student in the UA's Department of Planetary Sciences.
While Spitzer has observed dusty aftermaths of suspected asteroid collisions before, this is the first time scientists have collected data before and after a planetary system smashup. The viewing offers a glimpse into the violent process of making rocky planets like Earth.
Rocky planets begin life as dusty material circling around young stars. The material clumps together to form asteroids that occasionally run into each other. Although the asteroids often are destroyed, some grow over time and transform into proto-planets. After about 100 million years, the objects mature into full-grown, terrestrial planets. Our moon is thought to have formed from such a giant impact between proto-Earth and a Mars-size object when the sun was somewhere between 20 and 100 million years old.
In the new study, Spitzer – which includes technology developed at the UA – set its heat-seeking infrared eyes on the dusty star NGC 2547-ID8, which is a solar-type star that is about 35 million years old and lies 1,200 light-years away in the Vela constellation. Beginning in May 2012, the telescope began watching the star, sometimes daily.
A dramatic change in the star came during a time when Spitzer had to point away from NGC 2547-ID8 because the sun was in the way. When Spitzer started observing the star again five months later, team members were shocked by the data they received.
"We not only witnessed what appears to be the wreckage of a huge smashup, but have been able to track how it is changing – the signal is fading as the cloud destroys itself by grinding its grains down so they escape from the star," said Kate Su, an associate astronomer at the UA Department of Astronomy and Steward Observatory and co-author on the study.
"Imagine two asteroids, each 100 miles across, coming at each other at 40,000 miles per hour," said George Rieke, a UA Regents' Professor of Astronomy who led one of the instrument-developing teams on the Spitzer telescope project and a co-author on the study. "When they collide, much of the rock vaporizes and creates a cloud of gaseous minerals, which then condense into new, sand-like particles. Those particles smash into each other at incredible speeds, grinding each other down in the process."
A very thick cloud of dusty debris now orbits the star in the zone where rocky planets form. As the scientists observe the star system, the infrared signal from this cloud varies in proportion to what is visible from Earth. For example, when the elongated cloud is facing us, more of its surface area is exposed and the signal is greater. When the head or the tail of the cloud is in view, less infrared light is observed. By studying the infrared oscillations, the team is gathering first-of-its-kind data on the detailed process and outcome of collisions that create rocky planets like Earth.
"We are watching rocky planet formation happen right in front of us," Rieke said. "This is a unique chance to study this process in near real time."
Since terrestrial planet formation is a messy process that takes more than tens of millions of years, scientists rely on computer simulations to understand the process. The observations reported here open an avenue to compare on those simulations with how it happens in the real world, Rieke said.
The team is continuing to keep an eye on the star with Spitzer. They will see how long the elevated dust levels persist, which will help them calculate how often such events happen around this and other stars, and they might see another smashup while Spitzer looks on.
After Spitzer's expected end of operations later this decade, astronomers will catch a glimpse of the dust around these stars with the James Webb Space Telescope, or JWST, currently under construction and planned for launch in late 2018. JWST, too, will use technology developed at the UA to observe the most distant objects in the universe: a mid-infrared-wavelength camera developed by Rieke and a near-infrared-wavelength camera developed by Regents' Professor of Astronomy, Marcia Rieke, his wife.
"JWST will let us see if the dust clouds have dissipated and also let us probe the composition of the dust and gas in these systems much more powerfully than was possible with Spitzer," Su said. "Combining work with both telescopes over 20 to 25 years will provide us with a detailed look at how planets like Earth are assembled."
The results of this study are posted online on the website of the journal Science.

Genomics researchers of the University of Arizona's iPlant collaborative, housed in the BIO5 Institute, have helped unravel the genetic code of the rapeseed plant, most noted for a variety whose seeds are made into canola oil.
The findings will help breeders select for desirable traits such as richer oil content and faster seed production. Other potential applications include modifying the quality of canola oil, making it more nutritious and adapting the plants to grow in more arid regions.
In addition, they help scientists better understand how plant genomes evolve in the context of domestication. Brassica plants have been bred all over the world for centuries and resulted in produce and products diverse enough for supermarkets to place them across several different aisles.
Broccoli, cauliflower, Brussels sprouts, Chinese cabbage, turnip, collared greens, mustard, canola oil – all these are different incarnations of the same plant genus, Brassica.
"Whole-genome sequencing efforts like this one allow us to address two fundamental questions," said Eric Lyons, an assistant professor in the School of Plant Sciences at the University of Arizona College of Agriculture and Life Sciences, whose research team provides the software architecture for this and many other genome research projects. "How does the genetic information stored in the genome help us understand the functions of the organism, and what does the structure of the genome tell us about the evolution of genomes in general?"
The endeavor, which was led by institutions in France, Canada, China and U.S., revealed that the rapeseed (or Brassica napus) genome contains a large number of genes – more than 100,000 – due to the fact that it arose from a merger between two parent species, Brassica rapa (Chinese cabbage) and Brassica oleracea, a cultivar that includes broccoli, cauliflower, Brussels sprouts, collard greens and others.
The findings appear in the Aug. 22 issue of the journal Science and come at the heels of another international sequencing effort led by UA researchers, which revealed the complete genome of African Rice.
The computational power and cyberinfrastructure for running the analyses is provided by the iPlant Collaborative, a $100 million project funded by the National Science Foundation and headquartered in the UA's BIO5 Institute.
"The rapeseed genome has a very interesting history," said Haibao Tang, one of the leading authors of the study, who just joined the UA as a senior scientist for bioinformatics. "As a result of the merger event, it ended up with four copies of each gene. In this study, we looked at what happened after this merging event. For example, what genes were gained and what genes were lost."
"The Brassica group is extremely versatile with regard to human use," he said. "In all of the cultivars, we find something to eat. The genome defines what Brassicas are."
"It also defines what kids hate to eat," Lyons added. "The bitterness in some cultivars such as broccoli or Brussels sprouts comes from a class of compounds called glucosinolates, and we find that precisely those genes that code for those compounds were lost from the rapeseed genome."
The sequencing effort provides scientists and breeders with a map they can use to home in on certain genes and, by extension, the plant's metabolic pathways. For example, they could strive to create a cultivar of broccoli that's not bitter, or tweak the lipid biosynthesis pathway to favorably modify the oil content in rapeseed. Being able to modify the content of bitter-tasting compounds has implications beyond what meets the tongue, because in most plants, those chemicals also confer defense against pests.
"Depending on the cultivar in question, breeders may want to change the biochemistry," Lyons said. "You could knock down chemicals you don't want and ramp up others you do want. Or you may want to change the shape of the plant or parts of it. With Chinese cabbage, for example, we don't care too much about its oil content, but the size and shape of the leaves and how they taste. With rapeseed, it's the other way around."
The successful completion of the rapeseed genome sequence stems from a long-standing collaboration between Lyons and Tang, who comes to the UA from the J. Craig Venter Institute in Rockville, Maryland. Tang has specialized in writing the core algorithms of the Comparative Genomics’s platform, CoGe, which is powered by iPlant’s cyberinfrastructure, and provides a management layer for genomic data and tools to process them.
"Plugging into the infrastructure of iPlant allows us to scale far beyond of what we could do otherwise," Lyons said. "Each of these analyses takes hundreds of computing hours. In other words, either one computer working for hundreds of hours, or hundreds of computers working for one hour. With iPlant, we have access to a thousand or more computers to do this."
"We developed the tools people need to analyze large genomes, and now we can focus on discoveries," Tang said.
Lyons added: "Because we have been working to make these tools scalable, they are being used for virtually every genome analysis."
"Currently, CoGe and iPlant are being utilized to analyze 23,000 genomes from 17,000 organisms," Lyons said. "What started out as a plant genome platform has long expanded into all other areas of biology."
"We are currently involved with the genomes of birds, insects, bees, cows, fish, pig, horses and many plants," Lyons said. "The tool that we have developed for that past few years has become critical part of the ecosystem of bioinformatics tools that people regularly use."
"Leveraging iPlant we can empower scientists around the world to compare genomes among each other, and allow people to pick what they want to do, when they want it, and the way they want it," he added.Writer: Daniel StolteByline: Daniel StolteByline Affiliation: University Relations - CommunicationsHeader image: YesNo Image: Subheading: Genomics researchers of the University of Arizona's iPlant collaborative have helped unravel the genetic code of the canola plant.

This is the fifth and final post in a University of Arizona blog series about the University's STEM education initiatives and students conducting research abroad.

Austin Brown, a UA undergraduate researcher, is conducting research in Germany thorugh the Biological Research Abroad, Vistas Open! program. Brown is majoring in neuroscience, cognitive science and ecology and evolutionary biology. This summer, his research has been supported by the Howard Hughes Medical Institute.
Q: Why did you decide to get involved in research at the UA?
A: It sort of happened by chance. I was searching for a lab to volunteer in the summer before I started at the UA and Wulfila Gronenberg (an associate professor of neuroscience), who works mostly with bees and ants, welcomed me into his lab. He was very open to me doing whatever I was most interested in, so I ended up catching paper wasps on the UA Mall and conditioning or teaching them to expect a sugar reward when presented an odor. Before that I was actually in an environmental lab, looking at water contaminants. But while in Wulfi's lab, I became intrigued by the complexity of such a small brain, so I've been pursuing research in that field to this day.
Q: What are you doing in Germany?
A: I am in working in professor Wolfgang Rössler’s neuroethology lab at the University of Würzburg under Martin Strube-Bloss and in collaboration with Johannes Spaethe. Previously, Martin examined the olfactory processing of different odorants in the honeybee using electrophysiology. Different pheromones would be presented to the animal and he would analyze how the brain, particularly the antennal lobes, would respond to and discriminate between the different odors. I am a part of a similar project, but am using bumblebees as a model organism instead to compare. We hypothesize that odorants of similar structure would be processed more similarly than those that are less similar.
Q: Why is this particular area so important to you and your scientific colleagues?
A: I just really like it. I knew it was for me the moment I began doing research independently and found myself reading articles like they were literature, becoming enticed by the findings and conclusions as they spurred my curiosity and imagination. Sometimes I find myself realizing I could never really answer all the questions I thought up, but the prospect is tantalizing. What I find the most interesting about the brain is that it has taken a multitude of different forms throughout evolutionary time. Though a bee's brain is quite obviously different from our own, I find it intriguing that it can solve the same problems and perform analogous tasks such as complex learning/memory and navigation. By studying the diversity of neural mechanisms that exist in nature I hope to gain an understanding of how this wonderful organ called the brain works in general.
Q: How has your experience at the UA prepared you for your international research?
A: Being in a higher-level learning environment has matured me and made me more adept in conversing on scientific subjects with not only my peers, but professionals with the same interests. I may not have taken any German classes at the UA – I took Latin – but being involved in research has exposed me to the international side of science. And it has developed me further into what I hope to be in the future: not just an American but an international citizen.
Q: What are your plans after completing your undergraduate studies at the UA?
Brown: I plan to take some time to dedicate more hours to the lab and hopefully complete a reputable project worthy of publication in a high-ranking journal. Also, Martin, who spent some time as a post-doc at Arizona State University, has informed me that his old adviser is looking for an up-and-coming electrophysiologist to use Martin's old experimental setup, which I have been trained on while here in Germany. So I may choose to complete a master's degree in Phoenix and then possibly locate to a lab that studies a subject more suited to my interests. So far, though, I am just taking it step by-step and seeing what opportunities present themselves to me, as I had no idea previously that ASU would be possible in my future, being a native Tucsonan Wildcat and all.

We know that the better you eat, the better you think. That's what a growing body of research tells us.
Research also tells us that brain development does not stop when we are in our teenage years, but continues through the 20s. For most college students, these are very crucial points to note, indicating that proper nutrition – along with numerous other healthy lifestyle choices – are important to brain function and, ultimately, learning.
We enlisted Sarah Rokuski, is a nutrition counselor for the UA's Campus Health Service, to help identify some of the most important things students can do to ensure that they are getting proper nutrition. Here are Rokuski's top 10 tips.
Tip 1: Make occasional trips to a grocery store. Although picking up food on campus is more convenient, trips to the grocery store can save you money.
Tip 2:. Stock up on your favorite frozen fruits and veggies. Frozen fruits and veggies, without added sauces or seasoning, are a great option and are quick and easy to store and prepare.
Tip 3: Learn to cook. Learning to feel more comfortable in the kitchen opens up tons more opportunities for healthy eating. Learn how easy it is to prepare deliciously healthy recipes at the Cooking on Campus classes offered every other Tuesday at the UA Campus Recreation Center's instructional kitchen, located in the Outdoor Adventures area.
Tip 4: Make sure your plate has color. This can be done easily by adding your favorite fruits and vegetables to each meal.
Tip 5: Don’t skip meals. Skipping meals can lead to overeating and may lead to poor food choices. It also can affect your energy level and ability to focus. Prepare for busy days by packing your lunch or a few healthy snacks to bring along with you. For healthy meal and snack ideas, visit Cooking on Campus.
Tip 6: Eat mindfully. This means eating when you're hungry and stopping when you're full. It's easy to get into the habit of eating just because it's the time for it, or continuing to eat past the point of satisfaction. Listen to your body and trust that it will tell you when it needs food or that it has had enough.
Tip 7: Look for the Smart Moves symbol at Student Union eateries. The symbol indicates that a food is unprocessed, colorful, delicious and environmentally sustainable. Make a smart move to eat real foods, more plant-based foods, and less processed, bagged or boxed foods.
Tip 8: Don't diet. Diets often look attractive because they promise fast results, but these results may never come and if they do they often don't last. Dieting can also lead to weight gain, nutritional deficiencies, or even the development of an eating disorder. Focus on living an active lifestyle and making mindful food choices. If you or someone you know is struggling with an eating disorder, the UA's Counseling and Psych Services can help.
Tip 9: Eat locally and seasonally. Eating local and seasonal foods will not only benefit your health, but it's also good for local farmers, the environment and the local economy. To learn more about how to eat healthy, local, seasonally and sustainably, check out the UA Food Day Fair.

Under its strategic academic and business plan, "Never Settle," the University of Arizona has underscored its commitment to student engagement by ensuring 100 percent of students have the opportunity to be involved in some form of practical, engaged activity relevant to their future careers.
One of the students who has embraced that concept is UA undergraduate Jordan Richard Brock, who spent his summer in Turkey as part of Biomedical Research Abroad: Vistas Open!, a summer research program that grew out of the UA's Undergraduate Biology Research Program. Since the program was founded in 1992, more than 220 undergraduates have worked in laboratories located in dozens of countries outside of the U.S.
While abroad, Brock shared some thoughts about his experience.
This is the first in a five-part Q-and-A series highlighting the UA's efforts to promote science, technology, engineering and mathematics, the STEM fields, and the work of students like Brock.
Q: What is your current research?
A: I am working in Turkey studying the emerging biofuel crop, Camelina sativa. I am here to present my research at a Turkish Biology Congress, but also to make new collections of wild Camelina species from across Turkey. In previous years, I have traveled to Turkey, Georgia and Armenia to collect wild populations of various Camelina species.
Q: Why is this particular area of research so important?
A: I have been doing molecular phylogenetics in my laboratory at the University of Arizona to understand the evolutionary history of this genus. Because Camelina sativa is an emerging biofuel crop, we are interested in learning about the other species in the genus and how they may be used to further improve Camelina sativa.
Q: Why do you have a specific interest in Camelina sativa, and how has your research supported your studies?
A: I have an academic interest in studying Camelina because my project has allowed me not only to use the knowledge I have learned from my courses but also to build upon it. Lectures and laboratory experience are perfect complements to each other, and without practicing what you learn, eventually you will forget. My professional interest in my research is quite direct; the research I am doing as an undergraduate will help me excel in my future studies. I have been able to learn a variety of valuable laboratory skills but also skills such as analyzing data and critical thinking.
Q: Considering your work abroad, and your time at the UA, how do you feel you are becoming prepared for your future career?
A: My experience at the University of Arizona has prepared me very well for my international research. Classes such as plant systematics have been extremely helpful in developing my plant identification skills as well as teaching how to properly collect specimens. Furthermore, my principal investigator, Mark Beilstein, is an exceptional teacher, role model and friend; he always leads me in the right direction while giving me confidence to solve problems on my own. In my previous research trips abroad, I was accompanied by my principal investigator, but now I feel comfortable traveling and researching on my own.
Q: What are your long-term plans?
A: After I graduate I hope to pursue my Ph.D. in plant sciences or plant biology. My ultimate goal is to improve plant productivity and provide plant-based solutions to the world's decreasing arable land and water.

Say what you will about the parasitic lifestyle, but in the game of evolution, it's a winner.
Given that about half of all known species are parasites, biologists have long hypothesized that the strategy of leeching off other organisms is a major driver of biodiversity. Studying populations of Galápagos hawks (Buteo galapagoensis) and feather lice that live in their plumage (Degeeriella regalis), a group led by University of Arizona ecologists and evolutionary biologists has gathered some of the first field evidence suggesting that a phenomenon called co-divergence between parasites and hosts is indeed an important mechanism driving the evolution of biodiversity.
"The idea is really simple," said the study's lead author, Jennifer Koop, who is a postdoctoral fellow in the lab of Noah Whiteman in the UA's Department of Ecology and Evolutionary Biology. "Each time a host population splits into separate populations that potentially become different species, we predict that their parasites could do the same thing."
However, biologists have long struggled to test this hypothesis, as parasites are elusive.
"Often, the evolutionary trees of parasites and their hosts are congruent – they look like mirror images of one another," said Whiteman, who is an assistant professor in EEB, a joint assistant professor in the Department of Entomology and the School of Plant Sciences, and a member of the UA's BIO5 Institute. "But because parasites tend to be inside or attached to hosts, their distributions are difficult to study."
"We found the lice are passed on from mother to babies during brooding, almost like genes," Whiteman said. "They're evolutionary heirlooms, like your family's silverware or engagement ring diamond."
Because the hawks pass on the feather lice from generation to generation, the researchers wanted to know whether the louse populations diverge between populations of hawks and between individual hawks, or whether the populations of the birds and the lice diverged independently of each other.
Remarkably, the findings, which are published in the journal Biology Letters of the Royal Society, revealed that the population structure of the lice matched that of the birds across the archipelago, even though the two are very different species.
"To the lice, each bird is an island, and their populations are very different from bird to bird," Whiteman said. "The same pattern is repeated between bird populations on different islands. It's like Russian dolls."
In other words, the lice living on any one bird and its offspring are more closely related than the lice living on a different bird. As the birds diversify into distinct populations on each island, their parasites diversify with them. The findings help explain the rapid rate of parasite evolution, according to the research team.
"You have to be in the right spot at the right time to see this process happening," Koop said. "Our study empirically demonstrates an important evolutionary process in which the hawks separate into different populations, and the lice living on them do the same."
This process is hypothesized to lead to the formation of different species, in this case different species of hawks and lice, and may explain some of the extraordinary diversity seen among parasites, she said.
The team chose the Galápagos Islands, located 575 miles off the west coast of Ecuador, for the study because the species that colonized the geologically young group of islands have evolved in isolation, making the area an ideal natural laboratory.
"Of all the vertebrate species native to the Galápagos, the Galápagos hawk is the most recent arrival," Whiteman said. "So whatever is happening in terms of evolution of the bird population and the parasite population is most likely in the earliest stages of that process."
In four years of fieldwork on eight major islands, the team caught hundreds of Galápagos hawks – which later were released unharmed – and collected blood samples and feather lice for genomic analysis, in a partnership with the Galápagos National Park. Whiteman said the hawks' lice are specialized on their host species and the feathers they consume, and unable to survive on any other species.
Co-authors Karen DeMatteo and Patricia Parker, both at the Department of Biology at the University of Missouri-St. Louis, then used the DNA from the samples to generate a genetic fingerprint of each population. Parker helped with the fieldwork.
A better understanding of how parasites and their hosts coevolve has implications for biomedical sciences, according to Whiteman. In addition, it can help researchers who study parasites as evolutionary tags of the host species.
"The fact that we were able to work with these birds, which are the top predators in their habitat, and reveal some answers to fundamental questions in biology shows why such places should continue to be preserved," Whiteman said.
The study was supported by grants from the National Science Foundation, the Saint Louis Zoo's Field Research for Conservation, the University of Missouri Research Board, the John Templeton Foundation, a UA Faculty Seed Grant to Noah Whiteman and a National Institutes of Health-PERT postdoctoral fellowship to Jennifer Koop.Writer: Daniel StolteByline: Daniel StolteByline Affiliation: University Relations - CommunicationsHeader image: YesNo Image: Subheading: A UA-led study provides some of the first evidence for the hypothesis of co-divergence between parasites and hosts acting as a major driver of biodiversity.Include in UANow: yesInclude in Olympic Coverage: noFeature on Olympic Page: noUANow Image:
The Princeton Review has named the University of Arizona one of the best higher education institutions in the nation for undergraduate education.
The UA is included in "The Best 379 Colleges: 2015 Edition," the annual college guide released by The Princeton Review, a Massachusetts-based education services company known for its test-prep courses, tutoring, books and other student resources.
"The UA community takes great pride in being recognized by The Princeton Review," said UA President Ann Weaver Hart. "We know that our inclusion means that University students are pleased with their overall experience at the UA and see true value in their UA education, whether it's the academic training, career-oriented support or the community aspects of being a Wildcat."
The Princeton Review does not rank the 379 colleges. But it does assign scores between 60 and 99 in several categories. The UA was included in several categories: 96 for sustainability or "green" initiatives; 87 for fire safety; 84 for quality of life; 79 for selectivity; 75 for academics; and 73 for financial aid.
The Princeton Review team relies on a survey of 130,000 students who attend the schools. The 80-question survey asks students to rate their schools on several topics – including the quality of the faculty, library resources, career services, financial aid offerings and social aspects of college – and report on their campus experiences.
"The University of Arizona offers outstanding academics, which is the chief reason we selected it for the book," Rob Franek, the guide's author and The Princeton Review's senior vice president and publisher, said in a prepared statement.
Also based on survey results, UA students reported being "happy" with the institution, saying the UA has "great" career services and lab facilities, while noting the University's "strong commitment to undergraduate research." Students also reported being pleased with campus life and found that the University offers "a place for you to fit in no matter what you want to get out of your college education."
Ultimately, only 15 percent of the nation's four-year colleges – and only four institutions outside of the country – were profiled.
"Every college in our book offers outstanding academics," Franek noted. "These colleges differ significantly in their program offerings, campus culture, locales and cost. Our purpose is not to crown one college 'best' overall or to rank these distinctive schools 1 to 379 on any single topic. We present our 62 ranking lists to give applicants the broader base of campus feedback to choose the college that's best for them."
The Princeton Review's announcement follows the UA's inclusion as a top 100 U.S. institution in Money magazine's "Best Colleges" list. Money also ranked the UA 12th among the top 25 "best colleges you can actually get into."
The Princeton Review considers a variety of factors in its rankings, including student surveys and institutional data from college administrators. The guide includes detailed profiles of each school and ratings in a variety of areas, such as academics, quality of life and financial aid.Editor: La Monica Everett-HaynesByline Affiliation: University Relations - CommunicationsHeader image: YesNo Image: Subheading: The UA is included in "The Best 379 Colleges: 2015 Edition."
