Hyperexcitability has long been considered a hallmark of painful neuropathies. Identification of mutations in a specific sodium channel in people wi...

Stanford study of sea squirt provides clue to human immune system

...petals are even tinier tentacle-like ampullae, the sensing organs that evaluate other sea squirts, determining who's related and who isn't. If two adjacent squirts aren't related, their respective ampullae blacken and shrivel upon contact. But when the squirts are related, they begin to physically fuse toget...

Gerardo Snchez Pea of the General Directorate for Biodiversity (DGB) of Spain's Ministry of the Environment explained that Kyoto Inventory produ...

TRAF3 protein is a key part of the early immune response to viruses

...to explain how immune cells called macrophages use sensing devices called Toll-like receptors (TLRs) to orchestrate just the right response to different types of infections. TLRs are on the outer membranes of macrophages and respond to germs by triggering the production of proteins called cytokines. Various ...

Let me hear your body talk: UH scientists mine biomedical data

...est subjects will be collected by state-of-the-art sensing systems that already exist in the laboratories of the investigators or will be acquired with support from this grant and will include thermal cameras, 3-D geometry video cameras and multimodality brain activity scanners. This hybrid system will be c...

Radar altimetry confirms global warming is affecting polar glaciers

...ta collected between 1996 and 2005 by ESA's remote sensing satellites ERS-1 and ERS-2, ESA's Envisat and Canada's Radarsat-1, they found Greenland's southern glaciers are now dumping twice as much ice yearly into the Atlantic as they did in 1996, accounting for nearly 17 percent of the estimated 2.54 millime...

Study of nutrients' effects on brain provides insight into appetite regulation

... that mTOR basically serves as a "check-point" for sensing energy changes, the researchers predicted that it could be manipulated to alter food intake. The mTOR pathway is very sensitive to "branched-chain" amino acids, particularly leucine, Dr. Seeley explains. In laboratory studies, he and his team found ...
