The so-called “fiscal cliff” — an increase in income tax rates, expiration of many tax benefits and automatic federal spending cuts known collectively as sequestration — still looms as a possibility come January 2. Unless a deal is reached, universities across the country will face unprecedented cuts in federal funding, including cuts to research and development funding. Kevin Stacey spoke with Clyde Briant, vice president for University research, about the implications of the fiscal cliff.(more…)
Hot flushes are not “in the head,” but new research suggests they may start there. A UA research team has identified a region in the brain that may trigger the uncomfortable surges of heat most women experience in the first few years of menopause.
Hot flushes – also called hot flashes – affect millions of people, and not just women. Yet, it is still unclear what causes the episodes of temperature discomfort, often accompanied by profuse sweating.
Now a team of researchers around Dr. Naomi Rance, a professor in the department of pathology at the UA College of Medicine, has come closer to understanding the mechanism of hot flushes, a necessary step for potential treatment options down the road. This research was published recently in the Proceedings of the National Academy of Sciences. (more…)
In 1985, a computer science team at Université de Montréal made animated film history by creating one of the first ever digital characters, named Tony de Peltrie. Their six-minute film, which received a standing ovation by computer graphics designers at a festival in San Francisco, marked a turning point in computer-generated imagery (CGI). The film’s creators were able to produce a human face that, although rudimentary, was able to communicate emotions to the audience in a convincing manner.(more…)
Berkeley Lab Scientists at Advanced Light Source Show Dislocations Can Be Induced by Pressure in Ultrafine Nanocrystals
Nanocrystals as protective coatings for advanced gas turbine and jet engines are receiving a lot of attention for their many advantageous mechanical properties, including their resistance to stress. However, contrary to computer simulations, the tiny size of nanocrystals apparently does not safeguard them from defects.(more…)
The perception of Congress as a gridlocked institution where little happens is overblown, according to new research by scholars at the University of Colorado Boulder and the University of Washington.
And the way much of Congress’ work gets done is through self-manufactured crises like the “fiscal cliff,” say political science professors Scott Adler of CU-Boulder and John Wilkerson of UW.
“Yes, Congress has taken on a more partisan tone in recent decades,” Adler said. “We do hear a lot about the conflicts between Democrats and Republicans on key pieces of legislation. But we’re also seeing Congress exceeding public expectations. Congress does govern.” (more…)
A Brown University class on the effect that climate change could have on human health has produced a free new curriculum for high school teachers. The nine-module unit, which reflects feedback from teachers, includes lecture background and ideas for warm-ups, in-class activities, and assessment.
PROVIDENCE, R.I. [Brown University] — Katherine Smith’s students had to wait until they came to Brown University to learn how climate change could affect human health. Now that Smith and her fall semester class have developed a rich new curriculum on the subject for high school teachers, future 10th to 12th graders might not have to wait so long.
The curriculum, a nine-module set of backgrounders, lecture notes and suggested lesson plans and classroom activities, is now available for free download. In 180 total pages, it covers topics ranging from an overview of climate change to more specific units such as how global warming could affect infectious disease, allergies, and the global food supply.

Researchers have found the first proof that a chemical in the brain called glutamate is linked to suicidal behavior, offering new hope for efforts to prevent people from taking their own lives.
Writing in the journal Neuropsychopharmacology, Michigan State University’s Lena Brundin and an international team of co-investigators present the first evidence that glutamate is more active in the brains of people who attempt suicide. Glutamate is an amino acid that sends signals between nerve cells and has long been a suspect in the search for chemical causes of depression. (more…)
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…)
