In work published in the June 2011 issue of Experimental Biology and Medicine, Kolossov, Spring and their co-investigators - a multidisciplinary team within the Institute for Genomic Biology at the University of Illinois - have transferred the concept of redox-sensitive Green Fluorescent Proteins (GFPs) to a quantitative Förster resonance energy transfer (FRET) imaging platform.

RICHLAND, Wash. -- By adding the right amount of heat, researchers have developed a method that improves the electrical capacity and recharging lifetime of sodium ion rechargeable batteries, which could be a cheaper alternative for large-scale uses such as storing energy on the electrical grid.

Heart function may be affected in people with Type 2 diabetes as early as adolescence, according to a new study that will be presented Sunday at The Endocrine Society's 93rd Annual Meeting in Boston.

Scientists from NASA's Goddard Space Flight Center in Greenbelt, Md., have produced groundbreaking global maps of land plant fluorescence, a difficult-to-detect reddish glow that leaves emit as a byproduct of photosynthesis. While researchers have previously mapped how ocean-dwelling phytoplankton fluoresce, the new maps are the first to focus on land vegetation and to cover the entire globe.

San Antonio, Texas (June 6, 2011)—Research presented at SNM's 58th Annual Meeting may mark the expansion of a novel imaging agent for an optical technique called near-infrared fluorescence (NIRF), which uses light energy to glean information about cells and tissues. NIRF combined with the newly synthesized agent can image dangerous blood clots hiding inside elusive veins, most commonly within the deep tissues of the thighs and pelvis, but potentially also in the coronary arteries.

San Antonio, Texas (June 6, 2011)—Preliminary research presented at SNM's 58th Annual Meeting is breaking new ground for the development of a brand new hybrid molecular imaging system. Simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI) is providing important diagnostic information about soft tissues and physiological functions throughout the body. Scans focused on screening suspicious lesions for cancer are already comparable to more conventional molecular imaging methods.

Troy, N.Y. – Engineering researchers at Rensselaer Polytechnic Institute are combining automation techniques from oil refining and other diverse areas to help create a closed-loop artificial pancreas. The device will automatically monitor blood sugar levels and administer insulin to patients with Type 1 diabetes, and aims to remove much of the guesswork for those living with the chronic disease.

A study conducted by VTT Technical Research Centre of Finland indicates that there is practically no difference between commercial petrol grades 95E10 and 98E5 sold in Finland as regards fuel consumption in normal driving. The finding is based on driving tests conducted by VTT using six used cars of different make under laboratory conditions.

Imagine plugging a USB port into a sheet of paper, and turning it into a tablet computer. It might be a stretch, but ideas like this have researchers at North Carolina State University examining the use of conductive nanocoatings on simple textiles – like woven cotton or even a sheet of paper.

COLUMBUS, Ohio – While violent video games may lead to more aggression and anger in players, a new study shows that the opposite is also true: relaxing video games can make people happier and more kind.

"With all the evidence about the dangers of violent video games, it's good to know that game players can choose games that will provide a positive experience," said Brad Bushman, co-author of the study and professor of communication and psychology at Ohio State University.

Two University of Minnesota Department of Earth Sciences researchers have developed an innovative approach to tapping heat beneath the Earth's surface. The method is expected to not only produce renewable electricity far more efficiently than conventional geothermal systems, but also help reduce atmospheric carbon dioxide (CO2) -- dealing a one-two punch against climate change.

A new study reports that a low-cost healthy lifestyle program, including self-weighing weekly or monthly, by pregnant women with pre-existing overweight can prevent them from gaining too much weight during early pregnancy. The researchers will present the results Sunday at The Endocrine Society's 93rd Annual Meeting in Boston.

Science fiction is fast approaching science fact as researchers are progressing rapidly toward "bottling" antimatter. In a paper published online today by Nature Physics, the ALPHA experiment at CERN reports that it has succeeded in storing antimatter atoms for over 16 minutes. While carrying around bottled antimatter like in the movie "Angels and Demons" remains fundamentally far-fetched, storing antimatter for long periods of time opens up new vistas for scientists struggling to understand this elusive substance.

An unusual signal detected by the seismic monitoring station at the Smithsonian Tropical Research Institute's research facility on Barro Colorado Island results from waves in Lake Gatun, the reservoir that forms the Panama Canal channel, scientists report. Understanding seismic background signals leads to improved earthquake and tsunami detection in the Caribbean region where 100 tsunamis have been reported in the past 500 years.

Participants in two weight-loss programs -- one involving traditional health club sessions and the other delivered online in a 3D virtual world -- lost similar amounts of weight and body fat, but the online contingent reported significantly greater gains in behaviors that could help them live healthier and leaner lives.
