What's Up UA? - Don’t Underestimate Your Mind’s Eye

UA study finds that objects in our visual environment needn’t be seen in order to impact decision making.

Take a look around, and what do you see? Much more than you think you do, thanks to your finely tuned mind's eye, which processes images without your even knowing.

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 inneuroscience, has found supporting evidence. Cacciamani's is the lead author on a co-authoredstudy, 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," Cacciamani said. "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 among vision scientists.

"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.

What's Up UA? - 'What I Wish I Had Known as a Freshman'

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 MeystreDiana 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, NGOs and businesses on climate issues.a Regents' Professor of Physics and Optical Sciences and director of the UA Biosphere 2 Institute. UA alumni also talk about their experiences and share advice in "Career After College: Alumni Share Tips for New Students."

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. 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.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.

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.Massaro: That the humanities and history courses would so enrich my entire life. I wish I had taken a lot more of them, even as a science major.  

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.

What's Up UA? - UA Undergraduate Researchers Take to the Radio

University of Arizona student researchers are now sharing their work in a public, nonacademic forum: on the radio.

The UA's Undergraduate Biology Research Program is partnering with KXCI 91.3 to produce "Thesis Thursday," a weekly segment featuring student researchers during "The Home Stretch," one of the station's shows.

"After the first segment, I got so many calls from people who were happy to hear students doing important work in the community," said Cathy Rivers, the host and producer of "The Home Stretch."

"We hear so much negativity in the media these days. Hearing about the students work and the excitement they have for their research, studies and future careers brings a very positive perspective to what our youth are doing in our community," Rivers said. "It gives our listeners a glimpse as to what is happening in different fields of study and what our future doctors and scientists are looking at today that will affect us in the future."

Shaina Hasan, an Honors College senior majoring in biochemistry and molecular and cellular biology, discussed her research experience abroad through the UA's Biomedical Research Abroad: Vistas Open! program. Hasan spent time in Singapore during the summer of 2013, investigating how interaction between two specific proteins could have implications in cancer development.

"It's important to share my research through the media because it makes science and research accessible to the public, getting them more interested about what UBRP and BRAVO! do for students and the impact research has on the community," Hasan said. "When the community learns about the University's research, they become more scientifically literate, which is important for understanding the science and technology that surrounds us." 

The segment airs at 4 p.m. each Thursday. Others planned include:

  • Sept. 11: Manny Vasquez, an Exceptional Research Opportunity Program student and now a UBRP student studying chemical engineering
  • Sept. 18: Stephanie Kha, an Honors College student studying biochemistry and molecular and cellular biology.
  • Sept. 25: Alec Perkins, an Honors College student studying molecular and cellular biology.
  • Oct. 2: Judith Menzl, an Honors College student studying molecular and cellular biology and linguistics.
  • Oct. 9: Baltazar Chavez-Diaz, an Honors College student studying biochemistry, mathematics, and molecular and cellular biology.
  • Oct. 16: Wonn Pyon, an Honors College student studying chemistry and neuroscience and cognitive science.

Segments are planned through the end of November.

"Humanizing the research that is done at the University is extremely important to ensure community support," said Ursula Tooley, a former UBRP student who earned her bachelor's neuroscience from the UA in May. She now works in Oregon.

On the show, Tooley spoke about her research with the UA Down Syndrome Research Group, under the direction of Jamie Edgin, an assistant professor of psychology. At the lab, Tooley aided in an investigation of sleep and language development in toddlers, contributing to the finding that inadequate sleep adversely effects language development among young children – something that can be even more complicated for toddlers with Down syndrome.

"I hoped that by sharing this in a more public forum – and with a different audience than those who read scientific papers – the information will reach parents of young children who might be able to use it," Tooley said. "Sleep is vitally important for the development of all kinds of skills, including those necessary to do well in school and interact with other children, so parents who might be concerned about how well their kid is sleeping should know that the earlier they act, the better.”

Victoria Farrar, a senior in the Honors College studying chemistry and ecology and evolutionary biology, was featured on the show over the summer and spoke about studying Gila monsters in Saguaro National Park in partnership with Kevin Bonine, the education and outreach director for Biosphere 2 and outreach initiatives director for the College of Science.

"Participating in the research was really valuable to me because I was able to share my work –which has local, ecological importance – with the broader community of Tucson," Farrar said. "I immediately realized this when a man called in after my segment was done about his own experiences with Gila monsters, and I was able to be brought back on the air to share even more information, especially ways that citizens could help our research.

"I think reaching out to the community is important, because as tax-paying citizens, they do fund the research we do at this university," she said. "Letting them know what we do, and how it is relevant to their lives, is critical."

What's Up UA? - Send Your Tweet – and Your Name – to an Asteroid

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?"

What's Up UA? - Brown Foundations' $2.5 Million Kicks Off Catapult Corp

Our modern world is changing faster than we can conceive and universities are at the forefront of progress. Often academic discoveries struggle to reach their intended markets, but a new and groundbreaking program launched at the University of Arizona will help ensure its best minds turn their original ideas into viable and profitable companies.

The Catapult Corporation – dubbed "Cat Corp" for short – is an initiative of Tech Launch Arizonaestablished to provide early-stage capital to the most promising startup companies emerging from UA researchers and students. A donor-funded venture capital not-for-profit organization, Cat Corp has been initiated with a $2.5 million gift from Tucson's Thomas R. Brown Foundations. The gift comes with an inspiring challenge to the philanthropic community to match it. And the eventual goal of the Cat Corp leadership is to grow a $10 million corpus of endowed funds. Cat Corp is designed to be a self-sustaining operation.

Finding innovative ways to bring research to market is a priority of the UA's leadership, as well as of UA community partners. It is also one of the tenants of UA President Ann Weaver Hart's Never Settle strategic academic and business plan.

"Our commitment to expanding the UA's reach means moving outward into our communities," Hart said. "Cat Corp will be a key way we achieve this goal as investing in startups can strengthen Arizona’s economic development for years to come."

But launching a new company takes more than a great idea, talent, and well-researched strategy. It takes money. Without funding to get startups up and running, researchers' years of hard work can remain unrealized. For example, ideas for new cancer drugs or next-generation solar panels might remain just that: ideas.

Enter Cat Corp.

Based on a financial commitment from a lead investor, Cat Corp will analyze the best ventures from university faculty and students each year. An experienced seven-member board of directors will carefully evaluate risk, assess market potential, and engage other potential investors.

"If it doesn't have high promise then we won't do it," said David N. Allen, vice president of Tech Launch Arizona. "This represents a more mature approach to technology commercialization, and it is a unique opportunity for donors to contribute to the commercialization of research and the success of the operation to benefit the university."

Many universities have funding for startups, but Cat Corp is progressive in that the financial proceeds from the sale of a successful startup come back to the UA. It works like this: Venture A is provided startup funds in part by Cat Corp. Venture A matures into a product sales company, is sold, and the proceeds of the sale, based on Cat Corp’s stock, are directed back to the UA Foundation. Based on the return on the original Cat Corp investment, the first $4 million is transferred to an evergreen pool for additional investments. Remaining returns, or anything upwards of $4 million, are then distributed: 15 percent is directed back to Tech Launch; 85 percent goes as philanthropic contributions to a campus college or unit as directed by the donor. Essentially, once the capital is raised from donors, all proceeds benefit university units.

Once funded by Cat Corp, these startups have the potential to grow into significant companies, transforming the local economy along the way. It's a targeted research-to-market strategy that's crucial in a time of exponentially growing technologies and economic competition.

"Some of those companies will be the backbone of Southern Arizona's new economy," Allen continued. "We have other examples of companies from university research that are at the cutting edge of their markets and are significant regional employers."

Sarah Smallhouse, President of the Thomas R. Brown Foundations, agrees. Her father, Thomas, founded Burr-Brown Corporation in 1956. Its legendary launch in a Tucson garage created semiconductor transistors. In 2000, Burr-Brown Corporation sold to Texas Instruments for $7.6 billion. Sarah believes her father’s legacy of innovation and entrepreneurship is alive at the UA, and that Cat Corp can help replicate his success for others.

"It takes a lot of things to get basic science to the point where somebody can effectively commercialize it," Smallhouse said. "I see Cat Corp as a critical link in the chain to turn a new invention into a business reality."

"For the faculty and students at the UA who have innovative ideas," she continued, "something like this is a huge help and, frankly, motivating. They know if they get their research to a certain point of development, the resources are there to make it a reality."

Cat Corp and initiatives like it are fundamental to both the University's Never Settle strategic plan and also its $1.5 billion comprehensive campaign, Arizona NOW. Both prioritize outreach and community impact. More information about Cat Corp is available online attechlauncharizona.edu. More information about Arizona NOW can be found at arizonanow.org.

What's Up UA? - New Veterinary Degree Program Made Possible by $9M Gift is Critical for State

The University of Arizona College of Agriculture and Life Sciences has been actively developing a program to train veterinarians in Arizona and help improve animal and public health. Thanks to a foundational gift of $9 million from the Kemper and Ethel Marley Foundation, the UA will soon be the home of the state's first public veterinary medical and surgical program to train doctors of veterinary medicine.

The new program, slated to begin in fall 2015, will help address the critical veterinarian shortage in rural Arizona communities and tribal nations, benefit bioscience businesses and promote public health.

In 2012 and 2013, the Arizona Board of Regents requested funding from the state Legislature for a veterinary medicine degree program at the UA. A consultative site visit by the American Veterinary Medical Association occurred in January, and a comprehensive AVMA site visit for program accreditation will happen soon. ABOR will consider the degree offering at its September meeting in Flagstaff.

Facing eight, nine or more years of college and student loan debt, some students abandon their lifelong dream of becoming a veterinarian before they even start. Most students have been paying an average of $50,000 annually, in tuition alone, if they can get into one of 28 accredited public and private programs in the U.S.

"The bottom line is it costs too much and it takes too long to become a veterinarian in the United States," said Noble Jackson, associate professor of practice in veterinary science and microbiology in the UA School of Animal and Comparative Biomedical Sciences.

One newly qualified Arizona veterinarian, for example, was recently told that he would never qualify for a home loan because of his debt-to-income ratio.

"These kids come out of school with tremendous debt and have to work for several years to get school debt paid off. So anytime, I think, that we can produce good quality, qualified veterinarians for much less cost, much less time and get them out in the workforce sooner, it's a big win all the way around," said Cottonwood cattle rancher Andrew Groseta. "It's a win for the students involved. It's a win for those of us in the cattle business and it's a win for society."

The UA program will run year-round so students complete their degrees faster, accumulate less debt and enter the workforce sooner. In what is called a distributive model, the final two semesters will be spent working in private veterinary practices, government agencies or other community partnerships to secure hands-on, real-world learning in communities throughout the state.

Other clinical training partners will include federal and state animal health labs and regulators, U.S. Border Patrol and Homeland Security, and animal shelter and rescue agencies. The UA already has letters of interest from many prospective partners.

"For me, real-world experience is something that is oftentimes lacking when students come to us," said Richard Panzero, DVM, of River Road Veterinary Clinic in Tucson and a member of the program's consultative board. "I think the distributive model is probably the way of the future. The UA program will provide students with an additional semester of professional training versus the traditional four-year program – more in the way of hands-on experience and more time to digest the massive amounts of information required of a veterinary student."

Currently, Arizona students interested in becoming veterinarians must compete for veterinary school admissions at out-of-state institutions, many of which favor resident students. For example, 1,600 applicants competed for 138 seats at Colorado State University. Only 55 of those seats are open to applicants outside Colorado, and just a handful are filled by Arizonans.

"Arizona students pay higher costs through nonresident or private tuition, incur more debt and often stay in the practices, or seek employment with the out-of-state veterinary practices and companies where they intern as part of the out-of-state education," said Shane Burgess, vice provost and dean of the College of Agriculture and Life Sciences. "We need the smart and dedicated people we train to stay here. Arizona's hard-earned tax dollars need to promote Arizona's future."

Facilities for students will be built, refurbished or renovated at satellite locations in Douglas, Yuma, Maricopa and in the Verde Valley. In these settings, students will have the opportunity to learn about border health issues, rural medicine, food safety, large-scale animal production and wildlife, as well as the cattle and dairy industries.

As a cost-saving measure, the program will not build a veterinary teaching hospital, which can cost tens of millions of dollars and place a very large continuing financial burden on institutions.

"A teaching hospital also creates a level of competition with private practitioners," Jackson added. "We don't want to compete with practicing veterinarians. We want to engage them and have them help teach our students in a hands-on clinical setting."

The UA team has investigated highly successful international programs that train DVMs in a similar time frame and are accredited by the AVMA.

The UA already provides a wealth of resources that would aid in the creation of a successful program, including the colleges of Medicine, Public Health and Pharmacy, as well as a food safety study group.

"We are really asset-rich in terms of developing a program," Jackson said. "We have numerous veterinarians employed at our Arizona Veterinary Diagnostic Laboratory and at other parts of the University of Arizona. We also have numerous agricultural assets: a working ranch in the northern part of the state and a farm on campus."

The state's cattle ranchers welcome the prospect of UA-trained veterinarians, according to Bas Aja, executive vice president of the Arizona Cattle Feeders' Association. "We are extremely excited about the depth and breadth of effort that's gone into researching, designing and shaping this new program and we think it will be tremendously successful."

What's Up UA? - Laser 'Lightning Rods' Channel Electricity Through Thin Air

By zapping the air with a pair of powerful laser bursts, researchers at the University of Arizona have created highly focused pathways that can channel electricity through the atmosphere.

The new technique can potentially direct an electrical discharge up to 10 meters (33 feet) away or more, shattering previous distance records for transmitting electricity through air. It also raises the intriguing possibility of one day channeling lightning with laser power.

Described in a paper published in The Optical Society’s new open-access journal Optica, the current system may have near-term, lifesaving applications in areas such as the remote detonation of land mines, the researchers speculate. The laser system could easily pinpoint an active land mine and then carry an electric pulse strong enough to safely discharge harmful explosives from afar.

The team used a femtosecond laser to create a thin column of plasma – a special charged state of matter – in the air between two electrodes. A femtosecond is one millionth of a billionth of a second. Femtosecond lasers emit pulses that last only a few tens of femtoseconds.

Before this narrow plasma channel has a chance to dissipate, an almost simultaneous burst from a nanosecond laser – lasting a million times longer than a femtosecond pulse – retraces the same path, giving it an extra jolt of heat and the staying power necessary to transmit electricity.

The team was led by Pavel Polynkin, associate research professor of optical sciences at the University of Arizona College of Optical Sciences.

"By creating a combined one-two punch of laser light, we could first open a doorway through the air and then wedge it open just long enough to control and direct electricity through the atmosphere," said Polynkin, the paper's corresponding author. "This incredibly rapid double burst of energy is what was needed to overcome some otherwise daunting challenges."

Using Lasers to Channel Lightning

The idea of using lasers to channel electricity through the air, which is not normally conductive, was first proposed in the 1970s and further explored through the 1990s. The research was based on the idea that by superheating a very narrow column of air, it would be possible to create a straight path along which an electric charge could flow.

These early attempts used nanosecond lasers, which were the most practical lasers at the time due to their intense power and very short duration. The highly focused laser beams superheated a narrow line of air molecules, stripping off their outer electrons and producing a filament of charged plasma. The higher-than-normal concentration of free electrons in the plasma overcame the atmosphere’s natural insulator properties, making it much more conductive. Under laboratory conditions, researchers were, at the time, able to produce a filament of approximately 1 meter in length.

With the advent of more advanced femtosecond lasers, however, Polynkin and his team felt they could utilize the advantages brought about by both femtosecond and nanosecond lasers and achieve much better results through combining the two types of lasers in a single powerful beam.

Earlier this year, a joint team from the UA and the University of Central Florida, which included the authors of the new Optica paper, presented a new approach involving a high-intensity laser beam inside a "dress beam" refueling the primary beam and sustaining it over much greater distances than were previously possible. 

"In both experiments, we used two synchronized laser pulses to produce plasma in air," Polynkin said. "But the nature of the second pulse is different in the two cases. Instead of the dress beam, which only lasted femtoseconds, we now use a much more energetic pulse of longer duration – several nanoseconds – that we call heater pulse."

Extending the Reach and Duration With More Lasers

The current breakthrough was achieved by sending a femtosecond laser light pulse as the "igniter" and a nanosecond pulse as a "heater" along the same path, and by understanding how the atmosphere behaves when it was subjected to these extremely energetic light pulses. The researchers recognized that it wasn't the actual plasma created by the lasers that made the atmosphere more conductive; it was the subsequent superheating that lowered the density of the filament of air. Without some additional input of energy, however, this zone of lower density quickly collapsed. To improve both distance and duration, a second energy source was needed to rapidly reheat the air, stabilizing the filament just long enough to carry an electrical current.

"Since the first femtosecond laser already blazed the trail, we were able to harness a second nanosecond laser, following the same path, to rapidly pump more heat into the system," said Polynkin. "This channel lasted considerably longer, so we had the potential to extend the previous distance record by more than tenfold."

The filaments the researchers created significantly lowered what is known as the electrical breakdown point, the voltage that is needed to overcome the insulating effect of the atmosphere. Lightning, because of its incredibly high voltage, routinely overcomes the air's natural resistance, although in highly random and unpredictable ways.

Based on their initial results, the researchers believe that other forms of heater beams, such as microwaves or long-wavelength lasers, could further increase the distances they were able to achieve, though other issues would need to be addressed before applications like channeling lightning could be achieved.

As a next step, the researchers are planning on using a microwave beam in place of the nanosecond laser to more efficiently heat the channel and perhaps achieve better results.

What's Up UA? - UA Fall Enrollment Sets Record for Diversity, Number of Freshmen

The University of Arizona will have another record-setting year with the greatest number of incoming freshmen, the highest overall enrollment and greater student diversity, preliminary figures indicate.

New enrollment data shows that the UA will welcome more than 10,000 freshman, transfer and returning undergraduate students – with more than 7,800 of those being incoming freshmen – when classes begin Monday. For fall 2013, there were about 9,600 new students, of which nearly 7,200 were new freshmen.

Also, a projected 41.4 percent of new freshmen are ethnically or racially diverse. Last year, that number was 41.3 percent, marking the first time it had surpassed 40 percent.

 

"We are going against the national trend; our enrollment is increasing during a time that the number of high school graduates has just begun to rebound from one of the lowest points in many years," said Kasey Urquidez, the UA's associate vice president and dean of admissions.

The preliminary enrollment figures also indicate strong academic quality among students. The estimated freshman SAT is 1114 with an average 3.4 high school grade-point average. The Honors College is expecting about 1,300 incoming freshman and transfer students. Their average freshman SAT is 1353 with an average high school GPA of 3.85, both increases over last year.

Data also indicates that students are primarily choosing studies in science, technology, engineering and mathematics, known as the STEM fields. 

Alex Urzua, an transfer student from Maricopa Community Colleges who already has an eye on medical school, said he chose the UA because of its physiology program.

"I felt that the UA would be a good place to network with faculty and doctors associated with the medical school here," Urzua said. "I have heard excellent things about the UA's academics and I feel the University will provide me with sufficient knowledge to pursue my dream of becoming a doctor."

The UA received more than 33,600 applications this year from prospective freshman students alone. Generally, that figures caps out at about 26,000, Urquidez said.

"We had an incredible response from prospective students from day one," Urquidez said. Final enrollment calculations are not solidified until the official 21st day of the academic year, at which point figures are reported to the Arizona Board of Regents. "Even so, this is the most freshman applications we have ever had."

Other points on the incoming class, based on preliminary data:

  • The total student enrollment, including undergraduate and graduate students, is projected to be 41,800. The total enrollment on the 21st day last fall was 40,621.
  • About 57 percent of incoming freshmen are Arizona residents.
  • The total number of UA students who will be living on campus in residence halls is 7,200.
  • Applications from Arizona residents were up 20 percent this year, with 7 percent more students enrolling over last year. The top five states for non-Arizona residents are California, Illinois, Washington, Colorado and Texas.
  • More than 2,000 transfer students are expected.
  • The top five declared majors, in order, are: pre-business, pre-physiology, psychology, biology and pre-pharmacy – most of which fall into the STEM fields.
  • Nearly 400 former students have re-enrolled to pursue an undergraduate degree.   
  • About 450 international students will be part of the freshman and transfer classes.

New Jersey twin sisters Corby and Kyler Williams, both incoming freshmen currently deciding on majors, chose the UA because of its reputation, size and school spirit, as well as the local weather.

Both considered institutions across the nation, but it was their high school guidance counselor who pointed them to the UA.

One campus visit sealed the decision for the Williams sisters. Also, their mother gave them encouragement, having moved from back East to Colorado for her college studies.

"We wanted to also go far away so that we could meet new people," said Corby Williams, who is rushing for a sorority. "We came to visit and loved it immediately. There was a good vibe from everyone we met and we felt at home here."

Tristen Vaughn, a Flinn Scholar from Phoenix, also was grew fond of the University because of its welcoming environment, she said.

"Out of all the other schools I visited, it was the only one where I felt comfortable," said Vaughn, who is studying neuroscience, cognitive science and mathematics, and who has already connected with three mentors.

"The friendly and engaging atmosphere caught and kept my attention. I am confident that I have a beautiful support system in place. Such a system has assured me, even in the early stages of starting college, that I can be successful once I graduate," she said.

Vaughn also took interest in the more rigorous Honors College curriculum. "I thought it it would be a challenge to graduate with honors. I made a promise to myself to go above and beyond whenever possible."

Urquidez said many students committed to the UA early for a number of reasons. For example, last fall the UA launched the Wildcat Promise, an initiative to inform applicants if they have gained admission into the University shortly after they apply.

"We've started working earlier with prospective students to give them the information about what the University offers," she said. "A lot of schools might see an increase in applications, but not an increase in the number of students who complete the application and enroll. For us, the numbers were up across the board. We are very proud of this class."

The fall class also is the first to be able to take advantage of the recently implementedGuaranteed Tuition Program, allowing students and families to predict college costs and providing an extra incentive to graduate on time. The UA program provides students with a constant tuition rate for eight continuous fall and spring semesters.

Also, the UA's more intentional recruitment focus resulted in substantial growth from a number of U.S. states as well as other countries.

"We analyzed past classes and focused more of our efforts on growing specific markets," said Mary Venezia, the UA's assistant director of enrollment initiatives.

In the U.S., the UA saw sizable growth among students from states that include California, Colorado, Connecticut, Nebraska, Illinois, Massachusetts and Nevada. Among international students, the UA drew from a number of countries that saw little or no enrollment last year: Bolivia, Colombia, Finland and Indonesia. The UA also saw notable increases among students from countries such as India, Japan, Norway and the Philippines.

"We have traveled to and recruited in many more countries over the last few years and we are now seeing students coming from some of those new areas," Urquidez said.

"We are really dedicated to continuing to diversify the student body, and that includes international students," she added. "We want to ensure that our students have a greater chance to interact with others from around the world and prepare them to compete and cooperate in a global society."

What's Up UA? - Remarkable Résumé: UA Student Journalist's Career Includes CNN, NYT Phoenix

Amer Taleb's journalistic talent took him to Japan this summer, where he and other winners of the Roy W. Howard National Collegiate Reporting Competition toured multiple cities on a nine-day study trip. While in Hiroshima, he bought a silver keychain in the shape of a coin that was inscribed with a charge to work toward a more peaceful world.

Later in the summer, he traveled to Mexico as part of the United for Service volunteer program. While there, he visited an orphanage in Tepoztlán, where he gave the keychain to a 17-year-old orphan as a reminder that it is possible to rebuild after a crisis. 

That act speaks loudly about who Taleb is and what he does as a University of Arizona School of Journalism senior. With a strong global perspective, Taleb is committed to helping those who have experienced extreme struggles in life.

For Taleb, journalism is an important conduit for social change. And while he is still in training, Taleb has gained recognition for his work nationally.

In his years as a UA journalism student, Taleb has worked with Arizona Public Media, the Arizona Daily Star, The New York Times' Phoenix bureau, The Associated Press and The Nation. He also was an associate producer intern at CNN, assisting with producing on-air segments, writing scripts and editing videos with news anchor Don Lemon.

"I'm extremely grateful for what I've been able to accomplish," Taleb said. "If my achievements indicate anything, it's that I owe so much to so many people."

For his outstanding work, Taleb was named one of the College of Social and Behavioral Sciences Magellan Circle Scholars in 2012. Earlier this year, he was a keynote speaker for the Magellan Circle Scholarship, which supports students who achieve academic excellence.

Taleb's accomplishments also drew the attention of UA PresidentAnn Weaver Hart , who wrote in a memo that Taleb "deserves great credit for all of the hard work that has led him to this point."

In 2013, while working with the Scripps Howard Foundation Wire in Washington, D.C., Taleb reported on the U.S. Supreme Court, covering the landmark Defense of Marriage Act and Proposition 8 cases.

"Those are two of the most monumental Supreme Court cases in recent history, and maybe ever," said Taleb, also a Chips Quinn Scholar, which is part of a national training program for students interested in journalism. "That I can say I was quite possibly the youngest journalist in that courtroom is extremely humbling."

Jody Beck, director of the Scripps Howard Foundation, notes Taleb's stamina and dedication.

"He is one of those people that I had to kick out of the office at 9 at night and tell him to go home and relax a little, just because he is so excited about what he is working on," Beck said. "He is very talented and passionate."

That passion was evident from the moment Taleb arrived at the UA. He launched the The Tucson Minaret to cover issues in the Muslim, Arab and refugee communities in Tucson. He also worked alongside Jeannine Relly, an assistant professor of journalism, studying government interaction with journalism in Iraq.

"I have never met a student who has been such an inspiration to fellow students, who has given so much back to the school and to other students," Relly said. "Amer exemplifies what we would hope for any student, that they take advantage of any opportunity and give back to their profession and to their colleagues."

What's Up UA? - Through Innovative Partnership, 'Hot Shot' Team Tackles Yuma Produce Perils

Agriculture is big business in Arizona, and industry leaders in Yuma County are teaming up with the University of Arizona to arm growers with science and information they need to swiftly tackle threats to their profitability.

The recently launched Yuma Center of Excellence for Desert Agriculture - YCEDA – will provide the latest research and information in pest management, food safety, plant diseases, water conservation and more.

Yuma, the winter vegetable capital of the world, is home to more than 175 different crops, with an annual gross economic return of $3.2 billion. About 90 percent of leafy greens consumed in the United States and Canada in the winter come through Yuma.

Yuma and the state depend on this economic engine that can fall prey to diseases, pests, drought, frost, labor, wildlife and even public relations challenges. The public-private partnership was created to provide rapid response to issues important for desert crop production systems and the sustainable, responsible practices of local farmers.

More than two dozen industry partners from Yuma and Salinas, Calif., have invested in the center, together committing more than $1.1 million over the next three years. The YCEDA's initiatives will be guided by on-the-ground industry needs. These needs are shared in arid lands around the world—approximately 40 percent of all agricultural land worldwide is arid and so this is no small thing. 

"One outcome we are planning for is that the YCEDA, together with Yuma County Cooperative Extension and the Yuma Experiment Station, will make UA's Yuma operations the pre-eminent place in the world for basic, translational and applied research in arid-land agriculture," said Shane Burgess, vice provost and dean of the College of Agriculture and Life Sciences.

A search has identified finalists for the YCEDA executive directorship.

"One of the goals of the center is to provide immediate solutions and impact," said Kurt Nolte, who directs UA's Yuma Experiment Station and Yuma County Cooperative Extension. Nolte chairs the Yuma Center of Excellence for Desert Agriculture's executive director search committee.

For more than a century, the UA's College of Agriculture and Life Sciences and UA Cooperative Extension have provided solutions to problems faced by growers. The Yuma Center of Excellence for Desert Agriculture takes these partnerships to a new level.

"In the world that we live in as research faculty, it can be difficult to obtain funding in a rapid way to combat a particular problem that producers face," Nolte said. "This is similar to a hot shot firefighting effort where these funds would be available immediately to deal with issues in a very rapid way."

The center's director will work with an advisory council to initiate the most effective and efficient responses to a variety of issues – from infectious disease to food safety – that may be encountered by agriculturalists. Problems that normally would require three years of research might be solvable within a few months under the new model.

One immediate need is finding strategies to battle Downy mildew disease in spinach.

"We don't have a clear mechanism for managing this disease," Nolte said. "This committee is talking about releasing funds quickly to gain greater insight on this disease before the winter produce season kicks in."

Also high on the priority list is combating a pest that carries a virus that damages citrus.

"Ongoing drought conditions are also a major concern and the center will be mobilized to assist desert growers if water restrictions become real," Nolte said.

YCEDA will tap into the research and knowledge of UA faculty as well as experts from around the country and world.

Speedy solutions are critical to the success of the industry, Nolte said. "Napa is to wine as Yuma is to agriculture. Well over 50 percent of Yuma's economic base is derived from agricultural commodities that are grown here."

He believes the center has the potential to attract new companies to partner in identifying and funding prioritized research.

"One of the benefits of having a center with the horsepower behind it is to attract outside companies to come to Arizona and invest in the infrastructure within our university," Nolte said.

Investors in the center could come from as far away as Mexico, Israel and the Middle East, where similar growing conditions exist, Nolte said.

Chairing the YCEDA advisory committee is investor Robby Barkley, president & CEO of Yuma'sBarkley Ag Enterprises, which produces leafy greens, cauliflower, broccoli, grains, melons, cotton and more. His family first came to Yuma in the 1880s.

He called the center "an investment in our future."

"Our goal is to have a world-class research group readily available to us," Barkley said. "What is the best solution to a problem today will be improved upon in the future, so we want to develop a system that continues to feed those better solutions to us."

The goal of the center is to help growers be more profitable. "We are trying to do more with fewer resources, and we need to make sure that food production for our country stays in our country," Barkley said.

The Yuma Center will garner future funds from philanthropy, competitive grants and contracts with industry.

Vic Smith, CEO of the Yuma-based JV Smith Companies, is also an investor and advisor to YCEDA. Through JV Farms, Smith farms more than 7,500 acres of winter vegetables, including lettuce, spinach and broccoli.

By investing in YCEDA, Smith hopes access to the latest information will boost his industry and profits.

"What I like about this is it's a very quick, responsive approach to dealing with problems. When you have a problem, you can't wait for the results of a five-year research grant. You need answers now, and that is the hope for this center."
