Study identifies how tamoxifen stimulates uterine cell growth and cancer
|
|
(University of California - San Francisco) University of California - San Francisco researchers have identified a new "feed-forward" pathway linking estrogen receptors in the membrane of the uterus to a process that increases local estrogen levels and promotes cell growth.

'Genetic arms race' between bacteria, viruses subject of stimulus grant
|
|
(Michigan State University) The oceans teem with microscopic bacteria that produce much of Earth's oxygen as they absorb carbon dioxide greenhouse gas. But fast-mutating viruses also populate the seas, attacking marine bacteria in an ages-old evolutionary arms race. A Michigan State University researcher will probe that ancient dynamic against the backdrop of environmental and climate change, and the pivotal role played by aquatic bacteria in maintaining the Earth's biological balance.

Virus-resistant grapevines
|
|
A good wine needs to ripen. But it's a long way to the barrel. Even before the harvest, the grapevines have to overcome all kinds of obstacles. Extremely hot or rainy periods can destroy entire crops, not to mention the wide variety of pests that can appear on the scene. Bugs such as the vine louse or the rust mite, fungi such as mildew, or viruses such as the "Grapevine fanleaf virus" (GFLV for short) can give the vines a hard time. The GFLV infects the grapevine and causes fanleaf disease, resulting in deformed and very yellowed leaves, smaller grapes and crop loss.
