Producing medicines in plant seeds

... aid of biotechnology (and this number should only grow in the future). To do this, scientists use genetically modified bacteria, yeasts, or animal cells that are able to produce human proteins. These proteins are then purified and administered as medicines. Examples of such proteins are antibodies, which...

Study uncovers a lethal secret of 1918 influenza virus

...virus does something to the host that allows it to grow really well," says Kawaoka. "But we don't know what that is." Knowing that the virus does something early in infection to trigger such a devastating immune response may provide biomedical researchers with clues about how to intervene and stop or m...

Brain networks strengthened by closing ion channels

...getfulness and susceptibility to distraction as we grow older. The research is also relevant to common disorders such as ADHD, which is associated with weaker regulation of attention and behavior. ADHD is highly heritable, and some patients with ADHD may have genetic changes in molecules that weaken th...

Long-lived deep-sea fishes imperiled by technology, overfishing

...od ?are another depleted species. Deep-sea fishes grow slowly because of limited food sources and slower metabolisms and many don't reach sexual maturity for 30 to 40 years, Heppell said. The harvest of older fish may have an even greater impact on these threatened populations because older fish are more...

Biodiesel won't drive down global warming

...s that expressed normal or shortened Hmga2 did not grow significantly, while cells in which Hmga2 contained disrupted let-7 sites did. In fact, the more that let-7 sites were damaged, the greater the number of colonies. Mayr also worked with MIT assistant professor Michael Hemann to inject these cells...
