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 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…)
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.

*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.

*Jeremy Copp to Speak at M-Days Conference in Frankfurt*
Hamburg, Germany, January 12, 2011 – comScore, Inc., a leader in measuring the digital world, today released 
data from the comScore MobiLens service, reporting key trends in the German smartphone market during the three month average period ending November 2010. The report ranked the leading smartphone operating system (OS) platforms in Germany according to their share of current mobile subscribers ages 13 and older. The November report found that Symbian led among smartphone platforms with 47.7 percent market share, followed by Apple (19.5 percent), Microsoft (13.7 percent), Google (10.6 percent) and RIM (4.8 percent). Google Android gained the largest market share and went up 9.2 percentage points compared to November 2009. (more…)
*UCLA scientists use new scientific method to verify vintage 4100 B.C. wine*
Analysis by a UCLA-led team of scientists has confirmed the discovery of the oldest complete wine production facility ever found, including grape seeds, withered grape vines, remains of pressed grapes, a rudimentary wine press, a clay vat apparently used for fermentation, wine-soaked potsherds, and even a cup and drinking bowl.

Large wildlife die-off events are fairly common, though they should never be ignored, according to the U.S. Geological Survey scientists whose preliminary tests showed that the bird deaths in Arkansas on New Year’s Eve and those in Louisiana were caused by impact trauma.
Preliminary findings from the USGS National Wildlife Health Center’s Arkansas bird analyses suggest that the birds died from impact trauma, and these findings are consistent with the Arkansas Game and Fish Commission’s statement. The State concluded that such trauma was probably a result of the birds being startled by loud noises on the night of Dec. 31, arousing them and causing them to fly into objects such as houses or trees. Scientists at the USGS NWHC performed necropsies—the animal version of an autopsy—on the birds and found internal hemorrhaging, while the pesticide tests they conducted were negative. Results from further laboratory tests are expected to be completed in 2-3 weeks. (more…)
