UMass Amherst Climate Model is First to Study Climate Effects of Arctic Hurricanes

AMHERST, Mass. – Though it seems like an oxymoron, Arctic hurricanes happen, complete with a central “eye,” extreme low barometric pressure and towering 30-foot waves that can sink small ships and coat metal platforms with thick ice, threatening oil and gas exploration. Now climate scientists at the University of Massachusetts Amherst and in England report the first conclusive evidence that Arctic hurricanes, also known as polar lows, play a significant role in driving ocean water circulation and climate.

Results point to potentially cooler conditions in Europe and North America in the 21^st century than other models predict. (more…)

USGS Study Tracks Pacific Walrus, Observes Effects of Arctic Sea Ice Loss on Behavior

ANCHORAGE, Alaska — Sparse summer sea ice in the Arctic over the past five years has caused behavioral changes in Pacific walruses according to research published by U.S. Geological Survey and Russian scientists. The effects on the walrus population are unknown.

“The loss of sea ice is the ‘why’ for the change in walrus behavior; the tracking data tells us the ‘where’ in terms of their new forage patterns,” said USGS Director Marcia McNutt. “What awaits to be seen is ‘how much will it matter?'” (more…)

Commentary: John E. Savage – Cybersecurity Needed in the Public Domain

President Obama designated October as National Cyber Security Awareness Month. We asked John E. Savage, the An Wang Professor of Computer Science, to share his views on what can and should be done to ensure cybersecurity at the national level. Savage is active in cybersecurity from both a policy and technology point of view, having spent the 2009-10 academic year in the U.S. Department of State as a Jefferson Science Fellow.

In a major policy speech delivered last week, Secretary of Defense Leon Panetta sparked a new discussion of cyberwarfare threats, warning that cyberattacks “could virtually paralyze the nation.” The three-part response Panetta outlined emphasizes new cyberwarfare capabilities in the Department of Defense, new policies and organizations across the federal government, and stronger partnerships between the government and international partners and domestic industry.

COLUMBUS, Ohio – Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.

The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. (more…)

EAST LANSING, Mich. — Soybeans are one of the largest commodity crops in the world.

They also are starting to play a major role in reducing our carbon footprint, providing improved environmental performance and replacing finite, non-renewable resources such as oil.

And this is where Ramani Narayan comes in. (more…)

‘Greener’ and more engaging experiments draw students in

As a college student, Michelle Driessen had an all-too-typical experience.

“I hated general chemistry,” she says. “I thought it was terribly boring.”

She had plenty of company. Experiments were all laid out in advance, and the goal seemed to be to get to a predetermined result without blowing up the glassware.

In the old days, “very few students appreciated the point of most general chemistry labs,” adds Driessen. “With cookbook chemistry, you couldn’t have anything go wrong or deviate [from what’s supposed to happen], but I find those things to be the most interesting part of science.” (more…)

*Damaged deep-sea corals discovered months after Deepwater Horizon spill*

Scientists are reporting new evidence that the Deepwater Horizon oil spill has affected marine life in the Gulf of Mexico, this time species that live in dark ocean depths–deepwater corals.

The research used a range of underwater vehicles, including the submarine Alvin, to investigate the corals. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). (more…)

Researchers at Yale University have developed a new way of seeing inside solid objects, including animal bones and tissues, potentially opening a vast array of dense materials to a new type of detailed internal inspection.

The technique, a novel kind of magnetic resonance imaging (MRI), creates three-dimensional images of hard and soft solids based on signals emitted by their phosphorus content. (more…)
