Discovery of wound-healing genes in flies could mitigate human skin ailments
Biologists at UC San Diego have identified eight genes never before suspected to play a role in wound healing that are called into action near the areas where wounds occur.
Helper cells aptly named in battle with invading pathogens
By tracking the previously unknown movements of a set of specialized cells, Whitehead Institute scientists are shedding new light on how the immune system mounts a successful defense against hostile, ever-changing ...
Structure helps yield drug 'hypersensitivity' tests for patients
(Phys.org) —From a patient's point of view, one of the unsettling things about taking a new drug is the possibility of unwelcome side effects or worse, dangerous allergic reactions. As drugs are being developed ...
Material screening method allows more precise control over stem cells
(Phys.org) —When it comes to delivering genes to living human tissue, the odds of success come down the molecule. The entire therapy - including the tools used to bring new genetic material into a cell ...

Researchers synthesize asymmetrical glycans
A team of investigators from the University of Georgia recently demonstrated the first method for synthesizing asymmetrical N-glycans. According to the study, published in the journal Science on July 25, th ...
Mosquito behavior may be immune response, not parasite manipulation
Malaria-carrying mosquitos appear to be manipulated by the parasites they carry, but this manipulation may simply be part of the mosquitos' immune response, according to Penn State entomologists.
How coral cures your ills
