Could new drug cure nearly any viral infection? Technology shows promise against common cold, influenza and other ailments, researchers say Posted: 26 Aug 2011 10:40 AM PDT Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago. However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection.

Molecular chaperones traffic signaling proteins between cells in plant stem-cell maintenance pathway Posted: 25 Aug 2011 11:16 AM PDT Plant biologists have discovered that proteins called chaperonins are an indispensable factor in making possible cell-to-cell trafficking of signals that maintain stem cells and enable plants to grow.
