*Researchers discover molecular mechanism behind drink’s prophylactic effect*

Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.

Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body’s sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG. (more…)

In the vast ocean where an essential nutrient—iron—is scarce, a marine bacterium that launches the ocean food web survives by using a remarkable biochemical trick: It recycles iron.

By day, it uses iron in enzymes for photosynthesis to make carbohydrates; then by night, it appears to reuse the same iron in different enzymes to produce organic nitrogen for proteins. (more…)

For thousands of years, nomadic herdsmen have roamed the harsh, semi-arid lowlands that stretch across 80% of Kenya and 60% of Ethiopia. Descendants of the oldest tribal societies in the world, they survive thanks to the animals they raise and the crops they grow, their travels determined by the search for water and grazing lands.

For centuries, jungle explorers from Europe and North America have created art of the plants they discover—pressing bright flowers and green tendrils onto herbarium sheets for prestigious museums and plant collections. But scientists in the most biodiverse countries lack easy access to this basic information needed to identify plants. The Global Plants Initiative, meeting Jan. 11-13 at the Smithsonian Tropical Research Institute in Panama, catapults biodiversity research to a new level, sharing plant collections in a massive online database of high-resolution scans.
