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. (more…)
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…)
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…)
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…)
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. (more…)
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…)
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.

COLUMBUS, Ohio – Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.
The bacterium, Burkholderia cenocepacia, causes a severe and persistent lung infection in patients with CF and is resistant to nearly all known antibiotics. Cystic fibrosis is a chronic disorder characterized by a buildup of mucus in the lungs and other parts of the body, and various types of lung infection are responsible for about 85 percent of deaths in these patients.
