Study reveals white nationalists’ reactions when genetics test results challenge their identity

UCLA researchers’ analysis of web posts shows coping mechanisms ranging from rejection to reinterpretation

A new study by UCLA researchers reveals the range of reactions — from rejection to reinterpretation to acceptance — after white nationalists learn that DNA ancestry test results indicate they may not be as white or European as they previously thought. (more…)

Evolution of a Bimetallic Nanocatalyst

Atomic-scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas, coal or plant biomass. A multi-national lab collaboration led by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has taken the most detailed look ever at the evolution of platinum/cobalt bimetallic nanoparticles during reactions in oxygen and hydrogen gases.

Fumes Keep Moths from Finding Flowers, Study Discovers

New research by the University of Washington and the UA shows that background odors can interfere with pollinators’ ability to find flowers.

Car and truck exhaust fumes that foul the air for humans also cause problems for pollinators.

In new research on how pollinators find flowers when background odors are strong, University of Washington and University of Arizona researchers have found that both natural plant odors and human sources of pollution can conceal the scent of sought-after flowers.  (more…)

Exercise reorganizes the brain to be more resilient to stress

Physical activity reorganizes the brain so that its response to stress is reduced and anxiety is less likely to interfere with normal brain function, according to a research team based at Princeton University.

The researchers report in the Journal of Neuroscience that when mice allowed to exercise regularly experienced a stressor — exposure to cold water — their brains exhibited a spike in the activity of neurons that shut off excitement in the ventral hippocampus, a brain region shown to regulate anxiety.

New Coal Technology Harnesses Energy without Burning, Nears Pilot-Scale Development

COLUMBUS, Ohio — A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale.

For 203 continuous hours, the Ohio State combustion unit produced heat from coal while capturing 99 percent of the carbon dioxide produced in the reaction. (more…)

Reappraisal Defuses Strong Emotional Responses to Israel-Palestine Conflict

Reappraisal is a widely-used cognitive strategy that can help people to regulate their reactions to emotionally charged events. Now, new research suggests that reappraisal may even be effective in changing people’s emotional responses in the context of one of the most intractable conflicts worldwide: the Israeli-Palestinian conflict.

“Negative intergroup emotions play a crucial role in decisions that perpetuate intractable conflicts,” observes lead researcher Eran Halperin of the New School of Psychology at the Interdisciplinary Center in Israel. (more…)
