UA Researchers Hunt Bomb-Eating Bugs

UA researchers are investigating bacterial eating habits as part of a $1 million study to determine the environmental fate of newly developed munitions.

University of Arizona researchers are studying the environmental effects of insensitive munitions compounds, or IMCs, which are new, more stable explosives that won’t detonate in response to heat or shock.

Not much is known about the environmental impact of IMCs, which the U.S. Department of Defense hopes will reduce injuries and fatalities among troops who handle explosives. (more…)

Golden Potential for Gold Thin Films

Berkeley Lab Researchers Direct the Self-Assembly of Gold Nanoparticles into Device-Ready Thin films

Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have directed the first self-assembly of nanoparticles into device-ready materials. Through a relatively easy and inexpensive technique based on blending nanoparticles with block co-polymer supramolecules, the researchers produced multiple-layers of thin films from highly ordered one-, two- and three-dimensional arrays of gold nanoparticles. Thin films such as these have potential applications for a wide range of fields, including computer memory storage, energy harvesting, energy storage, remote-sensing, catalysis, light management and the emerging new field of plasmonics.

“We’ve demonstrated a simple yet versatile supramolecular approach to control the 3-D spatial organization of nanoparticles with single particle precision over macroscopic distances in thin films,” says polymer scientist Ting Xu, who led this research. “While the thin gold films we made were wafer-sized, the technique can easily produce much larger films, and it can be used on nanoparticles of many other materials besides gold.” (more…)

Did Bone Ease Acid for Early Land Crawlers?

In a new paper in the Proceedings of the Royal Society B, scientists propose that the bony structures in the skin of many early four-legged creatures might have been there to relieve acid buildup in bodily fluids. Analysis of their anatomy suggests that as they ventured out of water, the animals would have had trouble getting rid of enough CO2 to prevent acid buildup.

PROVIDENCE, R.I. [Brown University] — Here’s an anatomical packing list for making that historic trip from water to land circa 370 million years ago: Lungs? Check. Legs? Check. Patches of highly vascular bone in the skin? In a new paper, scientists propose why many of the earliest four-legged creatures that dared breathe on land carried bony skin features. (more…)

Job Slowdown in April Halts Growth in Overall Confidence

ANN ARBOR, Mich.— Consumer confidence remained largely unchanged at improved levels in April as consumers were still hopeful about future job gains despite disappointing recent developments, according to economist Richard Curtin, director of the Thomson Reuters/University of Michigan Surveys of Consumers.

The Surveys, conducted by the U-M Institute for Social Research, have been monitoring consumer attitudes and expectations for over 60 years. (more…)

Thinking in a Foreign Language Helps Economic Decision-Making

In a study with implications for businesspeople in a global economy, researchers at the University of Chicago have found that people make more rational decisions when they think through a problem in a non-native tongue.

People are more likely to take favorable risks if they think in a foreign language, the new study showed. “We know from previous research that because people are naturally loss-averse, they often forgo attractive opportunities,” said UChicago psychologist Boaz Keysar, a leading expert on communication. “Our new findings demonstrate that such aversion to losses is much reduced when people make decisions in their non-native language.” (more…)

Researchers Give Long Look at Who Benefits From Nature Tourism

EAST LANSING, Mich. — Using nature’s beauty as a tourist draw can boost conservation in China’s valued panda preserves, but it isn’t an automatic ticket out of poverty for the human inhabitants, a long-term study at Michigan State University shows.

The policy hitch: Often those who benefit most from nature-based tourism endeavors are people who already have resources. The truly impoverished have a harder time breaking into the tourism business. (more…)

UCLA Researchers Combat Global Disease with a Cell Phone, Google Maps and a Lot of Ingenuity

In the fight against emerging public health threats, early diagnosis of infectious diseases is crucial. And in poor and remote areas of the globe where conventional medical tools like microscopes and cytometers are unavailable, rapid diagnostic tests, or RDTs, are helping to make disease screening quicker and simpler. (more…)
