Questions for Clyde Briant: What Does the Fiscal Cliff Mean for Research?

By Guest PostDecember 15, 2012Economyfederal spending cuts, fiscal cliff, income tax rates, tax benefits

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…)

What Causes Hot Flushes during Menopause?

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. (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…)

Nanocrystals Not Small Enough to Avoid Defects

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…)

Congress Works Better Than Many Think, New Research Shows

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…)

Brown and High Schools: Teaching Teens About Climate Change, Health

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. (more…)

Countering Brain Chemical Could Prevent Suicides

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…)
