A device designed by engineers at the Georgia Tech Research Institute (GTRI) is part of the Hurricane Imaging Radiometer (HIRAD), an experimental airborne system developed by the Earth Science Office at the NASA Marshall Space Flight Center in Alabama.
Known as an analog beam-former, the GTRI device is part of the radiometer, which is being tested by NASA on a Global Hawk unmanned aerial vehicle. The radiometer measures microwave radiation emitted by the sea foam that is produced when high winds blow across ocean waves. By measuring the electromagnetic radiation, scientists can remotely assess surface wind speeds at multiple locations within the hurricanes. (more…)
Unique UCLA program that teaches social skills proves effective over long term
Teenagers with autism spectrum disorder are in a bind. The disorder is characterized by impairments in communication and social interaction, but it’s a continuum, so some teens diagnosed with ASD are considered high functioning and healthy enough to be “mainstreamed” in school.
But without the proper social skills, even mainstreamed teens don’t quite fit into the general social milieu of middle school or high school. As a result, they suffer from all the slings and arrows of that world.
Since 2006, however, the UCLA PEERS (Program for the Education and Enrichment of Relational Skills) clinic has assisted high-functioning teens with ASD by literally teaching them the strategies they need to fit in better with their peers. And while previous research demonstrated that the program was effective, it wasn’t known whether the new skills “stuck” with these teens after they completed the PEERS classes. (more…)
Berkeley Lab and SLAC Researchers Study Key Protein Complex Crucial to Photosynthesis
Future prospects for clean, green, renewable energy may hinge upon our ability to mimic and improve upon photosynthesis – the process by which green plants, algae and some bacteria convert solar energy into electrochemical energy. An artificial version of photosynthesis, for example, could use sunlight to produce liquid fuels from nothing more than carbon dioxide and water. First, however, scientists need a better understanding of how a large complex of proteins, called photosystem II, is able to split water molecules into oxygen, electrons and hydrogen ions (protons). A new road to reaching this understanding has now been opened by an international team of researchers, led by scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and SLAC National Accelerator Laboratory.
Using ultrafast, intensely bright pulses of X-rays from SLAC’s Linac Coherent Light Source (LCLS), the research team produced the first ever images at room temperature of microcrystals of the photosystem II complex. Previous imaging studies, using X-rays generated via synchrotron radiation sources, required cryogenic freezing, which alters the samples. Also, to catalyze its reactions, photosystem II relies upon an enzyme that contains a manganese-calcium cluster that is highly sensitive to radiation. With the high-intensity femtosecond X-ray pulses of the LCLS, the research team was able to record intact images of these clusters before the radiation destroyed them. (more…)
UA student Jason Xu has been recognized by the College of Science for his undergraduate research.
Wuhan, China and Tucson, Ariz.: These cities are thousands of miles apart, but they have one commonality – University of Arizona student Jason Xu.
A Chinese native and mathematics senior in the Honors College, Xu was selected as the recipient of this year’s Excellence in Undergraduate Research award by the UACollege of Science at its Galileo Circle reception event.
The award “is a huge honor and means a lot to me. I feel really good to be representing the math department,” Xu said. (more…)
ANN ARBOR, Mich.— In parts of the world without reliable electricity, a pedal-powered nebulizer could provide life-saving asthma treatments. Small wax-filled sleeping bags could keep premature infants warm. A salad spinner centrifuge for blood samples could help clinicians diagnose anemia.
University of Michigan researchers have cataloged more than 100 such technologies in a new wiki of medical devices designed for resource-limited settings. The Global Health Medical Device Compendium, an open-source inventory, is hosted by the popular appropriate technology wiki Appropedia. It is expected to serve as an important communication vehicle for end users, non-governmental organizations, researchers and others to help advance such technologies. (more…)
Sharing scientific knowledge is a fundamental part of university life. Regardless of whether you’re an undergraduate or a tenured professor, everyone has the responsibility of spreading their knowledge as widely as possible.
Why would you want to, though? “For a variety of reasons,” answers William Raillant-Clark, Press attaché at Université de Montréal’s Office of Communications and Public Relations. “The media is an excellent vehicle for communicating your ideas or your discoveries to the general public, and it can also draw the attention of your research peers to your work. This is one of the reasons why funding partners and potential research directors take into consideration science outreach work.” (more…)
ANN ARBOR, Mich.— A year after the crisis at Japan’s Fukushima Daiichi nuclear power plant, scientists and engineers remain largely in the dark when it comes to fundamental knowledge about how nuclear fuels behave under extreme conditions, according to a University of Michigan nuclear waste expert and his colleagues.
In a review article in this week’s edition of the journal Science, U-M’s Rodney Ewing and two colleagues call for an ambitious, long-term national research program to study how nuclear fuels behave under the extreme conditions present during core-melt events like those that occurred at Fukushima following the March 11, 2011, magnitude 9.0 earthquake and tsunami.

COLLEGE PARK, Md. – What does love look like? A dozen roses delivered on an ordinary weekday? Breakfast in bed? Or just a knowing glance between lovers?
While outward displays of love are fairly easy to discern, a researcher in the College of Behavioral and Social Sciences is taking a decidedly “inward” approach to documenting this most complex of human emotions. (more…)
