Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is losing mass at an accelerating rate, according to a new study. This mass loss is equally distributed between increased iceberg production, driven by acceleration of Greenland’s fast-flowing outlet glaciers, and increased meltwater production at the ice sheet [...]

Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. A new article provides some of the first evidence in mice and rats that new neurons sprouted in the hippocampus cause the decay of short-term fear memories in that brain region, without an overall memory loss.

Researchers are working to develop futuristic communications systems that could help protect frontline troops. Building on work completed recently for the UK Ministry of Defence, the project is aimed at investigating the use of arrays of highly specialized antennas that could be worn by combat troops to provide covert short-range person-to-person battleground communications.

As more people are diagnosed with H1N1 influenza infection, some will be admitted to hospital. The most severely affected may be treated in the intensive care unit and placed on a mechanical ventilator to help them breathe while they recover from the infection.
Novel nanomaterials are scheduled to blast off into orbit on November 16 aboard Space Shuttle Atlantis. The project seeks to test the performance of the new nanocomposites in orbit. The materials will be mounted to the International Space Station’s outer hull and exposed to the rigors of space.

A new study has shown that when preparing frozen foods, adolescents are less likely than adults to wash their hands and are more susceptible to cross-contaminating raw foods while cooking.
Astrophysicists have discovered two earth sized bodies with oxygen rich atmospheres; however, there is a bit of a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves, as they are not planets but are actually two unusual white dwarf stars.
Structural biologists have described the architecture of the complex of protein units that make up the coat surrounding the HIV genome and identified in it a “seam” of functional importance that previously went unrecognized. Those findings could point the way to new treatments for blocking HIV infection.

Zoo Atlanta recently became the first zoological institution in the world to obtain voluntary blood pressure readings from a gorilla. This was made possible by the Gorilla Tough Cuff developed by Georgia Tech students.

Researchers have identified the important role a protein plays in the body’s first line of defense in directing immune cells called neutrophils toward the site of infection or injury.
