Aurora Borealis breaks new grounds -- and old ice
11-30-2007 · EurekAlert!It can crush ice sideways and stay precisely on station to an accuracy of a metre. It can drill a hole 1,000 meters deep into the seabed while floating above 5,000 meters of ocean and it can generate 55 megawatts of power. So far, Aurora Borealis is the most unusual ship that has never been built, and it represents a floating laboratory for European science, a breakthrough for polar research and a very big headache for international lawyers.

- Melting of the Greenland ice cap may have consequences for climatic change
05-07-2007 · EurekAlert!
At the last ice age, before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which covered the British Isles had already begun to affect the circulation of the ocean currents. Based on this observation, scientists consider that the acceleration of the melting of the Greenland ice cap could play an important role in the development of climate change.

- Hot spot on Enceladus causes plumes
12-17-2007 · EurekAlert!
Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so hot intellectually hot, it's smokin'. The hot spot is causing plumes of ice and vapor to arise above Enceladus, says Washington University's William B. McKinnon.

- Sea snails break the law
04-24-2007 · EurekAlert!
Lizards gave rise to legless snakes. Cave fishes don't have eyeballs. In evolution, complicated structures often get lost. Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated. A group of sea snails breaks Dollo’s law, Rachel Collin, Staff Scientist at the Smithsonian Tropical Research Institute and colleagues from two Chilean universities announce in the April, 2007, Biological Bulletin.

- HYPER-CEST MRI breaks new ground in molecular imaging
10-19-2006 · EurekAlert!
Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for Magnetic Resonance Imaging that allows detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques. Called HYPER-CEST, this technique could become a valuable tool for medical diagnosis, including the early detection of cancer.

- An old discovery could boost ethanol production from plant fiber
11-07-2006 · EurekAlert!
A discovery some 40 years ago is showing promise as a chemical pre-treatment that breaks down plant fiber. That could release the simple sugars in corn stalks or switchgrass so they can be fermented into ethanol. And that could add value to Iowa's crops or the fibrous co-products of ethanol production.

- Ground breaking research to end in tears
05-28-2007 · EurekAlert!
Winter heating, modern life and growing old are drying the tears in millions of eyes but it's no cause for celebration. When human tearsbreak-up too quickly eyes feel gritty, hot and scratchy -- even eyesight can become blurry. For many people the solution has been to useartificial tears, but they're expensive and they don't last as long the real thing.

- Sexual orientation affects how we navigate and recall lost objects, but age just targets gender
05-23-2007 · EurekAlert!
Researchers at the University of Warwick have found that sexual orientation has a real effect on how we perform mental tasks such as navigating with a map in a car but that old age does not discriminate on grounds of sexual orientation and withers all men’s minds alike just ahead of women’s.

- Current melting of Greenland's ice mimicks 1920s-1940s event
12-09-2007 · EurekAlert!
Two researchers here spent months scouring through old expedition logs and reports, and reviewing 70-year-old maps and photos before making a surprising discovery: They found that the effects of the current warming and melting of Greenland 's glaciers that has alarmed the world's climate scientists occurred in the decades following an abrupt warming in the 1920s.
