Viruses Zapped With Plasma Treatment Before They Can Attack Cells

Adenoviruses can cause respiratory, eye, and intestinal tract infections, and, like other viruses, must hijack the cellular machinery of infected organisms in order to produce proteins and their own viral spawn. Now an international research team made up of scientists from Chinese and Australian universities has found a way to disrupt the hijacking process by using plasma to damage the viruses in the laboratory environment, before they come into contact with host cells.

New Cotton Fabric Cleans Itself When Exposed To Ordinary Sunlight

Imagine jeans, sweats or socks that clean and de-odorize themselves when hung on a clothesline in the sun or draped on a balcony railing. Scientists are reporting development of a new cotton fabric that does clean itself of stains and bacteria when exposed to ordinary sunlight. Their report appears in ACS Applied Materials & Interfaces.

Immune Cells Exhausted By Chronic Viral Infection Can Be Revived

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion.

Yet exhausted immune cells can be revived after the introduction of fresh cells that act like coaches giving a pep talk, researchers at Emory Vaccine Center have found. Their findings provide support for an emerging strategy for treating chronic infections: infusing immune cells back into patients after a period of conditioning.

The results are published this week in Proceedings of the National Academy of Sciences Early Edition.
