Materials that change temperature in magnetic fields could lead to new refrigeration technologies that reduce the use of greenhouse gases, thanks to new research at the U.S. Department of Energy's Argonne National Laboratory and Ames National Laboratory.
Scientists carrying out X-ray experimentation at the Advanced Photon Source at Argonne — the nation's most powerful source of X-rays for research — are learning new information about magnetocaloric materials that have potential for environmentally friendly magnetic refrigeration systems.

All eyes are on where hurricanes make landfall, but the massive storms actually cause the most deaths inland, where severe flooding often surprises residents.
Now, researchers are learning how to predict where tropical storms and hurricanes will dump the most rain — even days after — and hundreds of miles away from — landfall.
Corene Matyas, an assistant professor of geography at the University of Florida, outlines new tools to predict how the storm’s intensity, distance it has moved inland and landscape topography alters its “rain shields” — the bands of heavy rain so visible in Doppler radar images.

The world is abuzz with the discovery of an extrasolar, Earthlike planet around the star Gliese 581 that is relatively close to our Earth at 20 light years away in the constellation Libra.
Bruce Fegley, Jr., Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has worked on computer models that can provide hints to what comprises the atmosphere of such planets and better-known celestial bodies in our own solar system.
New computer models, from both Earth-based spectroscopy and space mission data, are providing space scientists compelling evidence for a better understanding of planetary atmospheric chemistry.

A new way of looking at a previously abandoned mathematical model might help astronomers study and accurately identify an exotic clan of gravitational waves.
The waves in question come from small black holes or neutron stars in extremely elongated orbits around vastly larger black holes, says Dr. Lior Burko, an assistant physics professor at The University of Alabama in Huntsville (UAH). "This reopens an area of research that was closed several years ago."
The exotic gravitational waves are generated (as predicted by general relativity theory) when an orbiting compact object changes speed, accelerating as it approaches the larger black hole and slowing as it moves away.

New studies show that iron, the principal constituent of the innermost parts of the earth’s core, becomes unusually ‘soft’ at the extreme pressures and temperatures that prevail there. The findings enhance our possibility of understanding the innermost parts of the earth and how earthquakes occur.
The findings were attained by a team of Swedish and Russian researchers, who used advanced simulations on Swedish supercomputers. This new knowledge explains some of the seismic data-signals from earth tremors-that stations around the world gather and that have puzzled scientists until now.
“These new discoveries about the innermost part of the earth provide an explanation for the low velocity of the seismic waves deep down in the earth.

Children who have at least one parent who smokes have 5.5 times higher levels of cotinine, a byproduct of nicotine, in their urine, according to a University of Leicester led study published online.
Having a mother that smokes was found to have the biggest independent effect on cotinine in the urine – quadrupling it. Having a smoking father doubled the amount of cotinine, one of chemicals produced when the body breaks down nicotine from inhaled smoke to get rid of it.
Sleeping with parents and lower temperature rooms were also associated with increased amounts of cotinine.

What happens if you deprive a group of 7 and 8 year olds of computers, television and games consoles for two weeks?
Psychologist and head of the Department of Media and Communication at the University of Leicester, Professor Barrie Gunter, has been working with the BBC Panorama team to find out.
Twenty-three 7 and 8-year-old school children from a single year group in a primary school in the Manchester area took part. They included children with a wide cross section of interests, from those who spent their free time in front of a screen to others who led a more active life outside school. Their families were also recruited to take part.

While young people have been going to college in greater numbers over the past 20 years the Scottish higher education rate versus the English has been 'consistently and substantially' greater in Scotland, according to a unique study funded by the Economic and Social Research Council (ESRC).
The project, led by Dr Linda Croxford with Professor David Raffe of the University of Edinburgh, found that while the Scottish system encouraged young people to study beyond the age of 16, middle class students took most advantage.

Children and their teachers are already benefiting from online learning communities such as the Oracle Education Foundation's Think.com, but there is a real opportunity for richer learning with such systems that is yet to be tapped.
Elizabeth Hartnell-Young of the Learning Sciences Research Institute at the University of Nottingham and freelance statistician Karen Corneille of Victoria, Australia describe how they have taken Think.com as a case study and investigated how a free, password-protected online community can support children's learning.
"We found that many children engaged readily with the site," says Hartnell-Young. Even those children with less developed ICT skills benefited from interacting with others.

Solving one of the biggest problems in commercialization of fuel-cell-powered automobiles is the goal of a new $1.88 million research project on on-board hydrogen storage at the U.S. Department of Energy's Argonne National Laboratory.
To be practical, researchers say, the hydrogen storage system must be able to hold enough of the fuel for a driving range of 300 miles before refilling; no current technology meets this goal within the constraints of allowable weight and volume for passenger cars.
The Argonne research will investigate nanostructured polymeric materials as hydrogen storage adsorbents. Developed through an earlier collaboration between Argonne and the University of Chicago, the new polymer adsorbent material has shown great promise in preliminary tests.

More good news for coffee is making the "it" drink for 2007.
People who drink coffee are less likely to develop an involuntary eye spasm called primary late onset blepharospasm, which makes them blink uncontrollably and can leave them effectively ‘blind’, according to a study published in the Journal of Neurology Neurosurgery and Psychiatry.
The effect was proportional to the amount of coffee drank and one to two cups per day were needed for the protective effect to be seen. The age of onset of the spasm was also found to be later in patient who drank more coffee – 1.7 years for each additional cup per day.

Since the discovery of an Earth-like planet around Gliese 581 20 light years away in the constellation Libra, the topic of a new home has generated a lot of excitement.
Bruce Fegley, Jr., Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has worked on computer models that can provide hints to what comprises the atmosphere of a planet like that and better-known celestial bodies in our own solar system.
“The farther out you go in the solar system, the more water you find,” said Fegley.
