Military to study better pain relief in battle zones
... of late July. Its known that battlefield pain, if not
relieved adequately, can lead to post-traumatic stress disorders. A large multidisciplinary team of U-M scientists will use the grant to design multipurpose nanoparticles and test how well they perform several tasks under simulated physiological co...

Injection drug use the most important risk factor for HIV and HCV infections among Quebec prisoners

been detected by Canadian scientists near their glass sponge reefs, thus the Washington margin reefs could represent a new type of ecosystem on the shelf, one where the abundant biology is fueled by methane gas derived from ancient carbon in the sedi...
Insulin grown in plants relieves diabetes in mice; UCF study holds promise for humans
...y. Insulin typically is given through shots and not
pills so the hormone can go straight into the bloodstream. In Daniells method, plant cell walls made of cellulose initially prevent insulin from degrading. When the plant cells containing insulin reach the intestine, bacteria living there begin to sl...
Researchers find pathway that controls cell size and division

contain all the genetic material that they should. By coordinating cell size with growth rate, cells are able to maintain proper distribution of DNA. This work is also something of a cautionary tale about the limitations of genome sequencing. More ...

New research identifies anti-viral protein that may predict who might be at risk to develop lupus
