Protein receptor cools passion of 'kiss and run' nerve cells

...dea that these little packets, or vesicles, either released all or none of their neurotransmitter into the synaptic cleft," said Alford. "We've identified a specific molecular mechanism that targets the machinery that causes the fusion process and found that instead of an all-or-none release, the vesicle just...

Illegal trade is propelling rare turtle toward extinction, new report

A new report released today finds that the illegal trade in the Roti Island snake-necked turtle, found only on one island in Indonesia, has left it all but extinct in the wild. Exotic pet enthusiasts in Europe, North America and East Asia are fueling the illegal trade fo...

Brain's own cannabis compound protects against inflammation

...nd that the brain's natural "endocannabinoids" are released after brain injury and are believed to alleviate neuronal damage. However, scientists have not understood how such substances act within the brain's own immune system. Now, experiments by Oliver Ullrich and colleagues have pinpointed how one of the ...

Researchers find molecular 'brake' to cell death

...y are "pro-survival factors" that prevent CC, when released from the mitochondria, from "seeing" Apaf-1 in the cytoplasm, Tang says. "When we induced some cell stress and damage, the low levels of CC that came out from the mitochondria were ineffective because they are sequestered by an ocean of free nucleo...
