Carnegie Airborne Observatory: Mapping Video

Some 55% of tropical forests are negatively affected by land use practices and deforestation worldwide. But the ability to penetrate the canopy to see what’s going on has been lacking until now.

Global Ecology’s Greg Asner’s group has developed new airborne methods to peer through the canopy to measure and map, in beautiful 3-D, the underlying vegetation, degradation and deforestation, and the amount of carbon stored and emitted in these forests. (more…)

Why Coffee Protects Against Diabetes

Health, Science

*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…)

‘Hot-Bunking’ Bacterium Recycles Iron to Boost Ocean Metabolism

Science

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…)

Scientists take new look at solar corona

One of the most enduring mysteries in solar physics is why the Sun’s outer atmosphere, or corona, is millions of degrees hotter than its surface. (more…)

Microsoft Survey Highlights Cloud Movement Across the US

Technology

*Microsoft today named some of the country’s top “cloud-friendly” U.S. cities. The rankings are based on the results of an extensive survey in which 2,000 IT decision makers nationwide discussed how they are adopting and using cloud computing.*

REDMOND, Wash. – Jan. 12, 2011 – The forecast for cloud computing across key U.S. cities calls for new lines of business, more need for IT services, and potential job growth, according to a new survey released today by Microsoft.

Microsoft released the results of the study this week after interviewing more than 2,000 IT decision-makers in 10 U.S. cities. (more…)

Video Explores What Happens in Africa ‘When the Water Ends’

Culture, Environment

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.

Online Access to the Plants of the World Is Available

Nature, Science

*The Global Plants Initiative Meets at the Smithsonian in Panama Jan. 11-13*

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.
