Scientists isolate new antibodies to fight human respiratory syncytial virus (RSV)

Science Daily - Mon, 13/02/2017 - 6:12pm
Researchers have developed a new antiviral strategy to fight human respiratory syncytial virus (RSV), a leading cause of lower respiratory tract infections in children. The approach hinges on the use of single-domain antibodies, also known as Nanobodies®, which target and neutralize a vital protein in the virus, rendering it unable to enter lung cells.

Researchers discover a new link to fight billion-dollar threat to soybean production

Science Daily - Mon, 13/02/2017 - 6:11pm
Invisible to the naked eye, cyst nematodes are a major threat to agriculture, causing billions of dollars in global crop losses every year. A group of plant scientists recently found one of the mechanisms cyst nematodes use to invade and drain life-sustaining nutrients from soybean plants. Understanding the molecular basis of interactions between plants and nematodes could lead to the development of new strategies to control these major agricultural pests and help feed a growing global population.
