Global warming over the next 40 years will cut through Arctic transportation networks like a double-edged sword, limiting access in certain areas and vastly increasing it in others, a new UCLA study predicts.
“As sea ice continues to melt, accessibility by sea will increase, but the viability of an important network of roads that depend on freezing temperatures is threatened by a warming climate,” said Scott Stephenson, a UCLA graduate student in geography and the study’s lead author. (more…)
*Discovery of self-corrective healing process for polymer detailed this week in the journal Nature*
Imagine you’re driving your own new car–or a rental car–and you need to park in a commercial garage. Maybe you’re going to work, visiting a mall or attending an event at a sports stadium, and you’re in a rush. Limited and small available spots and concrete pillars make parking a challenge. And it happens that day: you slightly misjudge a corner and you can hear the squeal as you scratch the side of your car–small scratches, but large anticipated repair costs.
Now imagine that that you can repair these unsightly scratches yourself–quickly, easily and inexpensively–or that you can go through a car wash that can detect these and other more minor scratches and fix them as the car goes through the washing garage. Fantasy. Not exactly. Not anymore. Not according to a new discovery detailed in the April 21 issue of the journal Nature, and depicted in a short video interview and simulation. (more…)
ANN ARBOR, Mich.— Since 2003, the antiwar movement in the United States has had much to protest with Americans fighting in Iraq, Afghanistan and now Libya, but the movement—which has dropped off sharply the past two years—may be more anti-Republican than antiwar, says a University of Michigan researcher.
A new study by U-M’s Michael Heaney and colleague Fabio Rojas of Indiana University shows that the antiwar movement in the United States demobilized as Democrats, who had been motivated to participate by anti-Republican sentiments, withdrew from antiwar protests when the Democratic Party achieved electoral success, first with Congress in 2006 and then with the presidency in 2008.

AUSTIN, Texas — Global warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines of species at local scales, biologists from The University of Texas at Austin advise.
“Yes, global warming is happening. Yes, it is caused by human activities. And yes, we’ve clearly shown that species are impacted by global warming on a global scale,” says Parmesan, associate professor of integrative biology. (more…)
ANN ARBOR, Mich.— While exposed spent fuel rods at the failing nuclear reactors in Japan pose new threats, the worst-case scenario would still be unlikely to expose the public to catastrophic amounts of radiation, says a University of Michigan nuclear engineering professor who is an expert on this particular kind of reactor.
“For the public, I don’t believe it would be much higher than two additional chest x-rays,” said John Lee, a professor in the Department of Nuclear Engineering and Radiological Sciences, citing the results of the Three Mile Island accident. (more…)
ANN ARBOR, Mich.— While debate on climate change often strikes a caustic tone, the real impediment to meaningful dialogue is that the two sides often talk past each other in what amounts to a “logic schism,” says a University of Michigan researcher.
“In a logic schism, a contest emerges in which opposing sides are debating different issues, seeking only information that supports their position and disconfirms their opponents’ arguments,” said Andy Hoffman, the Holcim (U.S.) Professor of Sustainable Enterprise at U-M’s Ross School of Business and School of Natural Resources and Environment. “Each side views the other with suspicion, even demonizing the other, leading to a strong resistance to any form of engagement, much less negotiation and concession.” (more…)
Laminin, long thought to be only a structural support protein in the microenvironment of breast and other epithelial tissue, is “famous” for its cross-like shape. However, laminin is far more than just a support player with a “pretty face.” Two studies led by one of the world’s foremost breast cancer scientists have shown how laminin plays a central role in the development of breast cancer, the second most leading cause of cancer death among women in the United States. In one study it was shown how laminin influences the genetic information inside a cell’s nucleus. In the other study it was shown how destruction of laminin can play a detrimental role in the early stages of tumor development. (more…)
*New facility based in Singapore extends IBM’s global cloud delivery capabilities to meet growth market cloud needs of businesses in Asia Pacific*
SINGAPORE, – 07 Mar 2011: IBM today announced a US$38M investment in a new IBM Asia Pacific Cloud Computing Data Centre in Singapore, which will provide businesses with solutions and services to harness the potential of cloud computing. The new facility will extend IBM’s globally-integrated cloud delivery network with centres in Germany, Canada and the United States; and 13 global cloud labs, of which seven are based in Asia Pacific – China, India, Korea, Japan, Hong Kong, Vietnam and Singapore.
Scheduled to launch in April, the Centre will make available IBM’s comprehensive cloud services and technology portfolio via the company’s cloud delivery infrastructure. These services are designed to enable clients to reap the benefits of business and IT transformation; increase flexibility and agility; accelerate time to market; reduce costs; and increase security and compliance of public cloud environments.(more…)
