University of Illinois at Chicago College of Medicine 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. Their results are described online in the Proceedings of the National Academy of Sciences. Neutrophils are white blood cells that are activated by chemical cues t...

Zoo Atlanta recently became the first zoological institution in the world to obtain voluntary blood pressure readings from a gorilla. This groundbreaking stride was made possible by the Gorilla Tough Cuff, a blood pressure reading system devised through partnership with the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. Created as a senior design proj...

Novel nanomaterials developed at Rensselaer Polytechnic Institute are scheduled to blast off into orbit on November 16 aboard Space Shuttle Atlantis. The project, funded by the U.S. Air Force Multi University Research Initiative (MURI), seeks to test the performance of the new nanocomposites in orbit. Space Shuttle Atlantis will carry the samples to the International Space Station (ISS). The mater...

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 (ICU) and placed on a mechanical ventilator to help them breathe while they recover from the infection. While mechanical ventilation clearly saves the lives of many people felled by serious illness, in some cases, this supportive measur...

Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. That`s the conclusion of a report in the November 13th issue of the journal Cell, a Cell Press publication, that 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...

Scientists at the University of Liverpool are constructing highly sensitive detectors as part of an international project to understand the elements that make up the universe. The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a `fingerprint` of the inside of the atomic nucleus to understand the structure of all ma...
