Study Portends Greater Anticipated Global Warming

Current state-of-the-art global climate models predict substantial warming in response to increases in greenhouse gases such as carbon dioxide. The models, though, disagree widely in the magnitude of the warming we can expect. The disagreement among models is mainly due to the different representation of clouds. Some models predict that global mean cloud cover will increase in a warmer climate and the increased reflection of solar radiation will limit the predicted global warming. Other models predict reduced cloudiness and magnified warming. (more…)

Getting a Tighter Grip on Cell Division

Science

*Molecular “machine” responsible for pulling chromosome copies apart is isolated and seen in action outside the cell*

The dance of cell division is carefully choreographed and has little room for error. Paired genetic information is lined up in the middle of the cell in the form of chromosomes. The chromosomes must then be carefully pulled apart so that the resulting daughter cells each have an identical copy of the mother cell’s DNA. (more…)

Microsoft Offerings Help Overcome Holiday Overload

Technology

*With the holiday shopping season just around the corner, Microsoft has been partnering with celebrities to promote Bing as a cure for holiday overload. The company is also showcasing new PCs as gift ideas and partnering with Southwest Airlines to offer travelers a free holiday photo with Santa.*

REDMOND, Wash. – Nov. 24, 2010 – As Black Friday looms, Microsoft is trying to help consumers survive the holiday crunch through high-tech gift ideas, a stress-free shopping experience, and even a chance to meet St. Nick himself.

The day after Thanksgiving has long marked the start of the holiday shopping season, and Black Friday has become the busiest shopping day of the year. Microsoft has been busy trying to get out the word that Bing can help shoppers “cut through the clutter this holiday season,” said Lisa Gurry, director of marketing. (more…)

Biologists Report More Bad News for Polar Bears

*Climate change will force them south, where they are unsuited for the diet*

Will polar bears survive in a warmer world? UCLA life scientists present new evidence that their numbers are likely to dwindle.

As polar bears lose habitat due to global warming, these biologists say, they will be forced southward in search of alternative sources of food, where they will increasingly come into competition with grizzly bears.

To test how this competition might unfold, the UCLA biologists constructed three-dimensional computer models of the skulls of polar bears and grizzly bears — a subspecies of brown bears — and simulated the process of biting. The models enabled them to compare the two species in terms of how hard they can bite and how strong their skulls are. (more…)

Samlink Turns to IBM for New Services Agreement

Technology

*IBM to manage the IT infrastructure of over 400 bank branch offices and deploy a cloud learning environment*

HELSINKI, Finland, – 24 Nov 2010: IBM announced today it has signed a new agreement with Samlink to manage the information technology (IT) infrastructure for the company’s more than 400 bank branch offices across Finland. The five-year, EURO 28 million agreement signed this month follows the IT agreement between the two companies inked one year ago in November 2009 in which IBM enabled Samlink to achieve greater efficiency in its data center operations.

IBM will manage overall IT operations and internal workstations for Samlink and its clients including self-service kiosks, wireless networks, workstation and maintenance, desktop, servers, and printers. (more…)

EAST LANSING, Mich. — Crop diversification with shrubby legumes mixed with soybean and peanuts could be the key to sustaining the green revolution in Africa, according to a Michigan State University study.

The study, which appears in the Nov. 22 issue of the Proceedings of the National Academy of Sciences, states that diversifying crops would boost production of nutrient-enriched grain by 12 percent to 23 percent, said Sieglinde Snapp, a crop and soil scientist at Michigan State University’s Kellogg Biological Station who led the study.

Predicting Sea Level Rise: Understanding How Icebergs Form Could Lead to Better Forecasts

Environment

ANN ARBOR, Mich.— In an effort to understand how fast sea level could rise as the climate warms, a University of Michigan researcher has developed a new theory to describe how icebergs detach from ice sheets and glaciers. (more…)

Dealt a Bad Hand: Pathological Gamblers Are Also at Risk for Mental Health Disorders

Pathological gamblers are risking more than their money, they are also three times more likely to commit suicide than non-betters. A new Montreal inter-university study has shown these gamblers are also plagued by personality disorders. These findings, published in a recent issue of the Psychology of Addictive Behaviors, may have implications for developing improved targeted suicide prevention programs.

“The World Health Organization estimates that suicide is one of the top ten causes of death in the Western world,” says study co-author, Richard Boyer a Université de Montréal professor and researcher at the Centre de recherche Fernand-Seguin at the Louis-H. Lafontaine Hospital. “In addition, pathological gamblers account for five percent of all suicides. These staggering statistics motivated us to study the difference between gamblers and non-gamblers.” (more…)
