n experiment called "shining light through walls" would seem hard to improve upon.

But University of Florida physicists have proposed a way to do just that, a step they say considerably improves the chance of detecting one of the universe's most elusive particles, a candidate for the common but mysterious dark matter.

By utilizing ideas developed in disparate fields, from earthquake dynamics to random-field magnets, researchers at the University of Illinois have constructed a model that describes the avalanche-like, phase-slip cascades in the superflow of helium.

Just as superconductors have no electrical resistance, superfluids have no viscosity, and can flow freely. Like superconductors, which can be used to measure extremely tiny magnetic fields, superfluids could create a new class of ultra-sensitive rotation sensors for use in precision guidance systems and other applications.

The periodic table of elements, all 111 of them, just got a little competition. A new discovery by a University of Missouri-Columbia research team, published in Angewandte Chemie, the journal of the German Society of Chemists, allows scientists to manipulate a molecule discovered 50 years ago in such as way as to give the molecule metal-like properties, creating a new, "pseudo" element. The pseudo-metal properties can be adjusted for a wide range of uses and might change the way scientists think about attacking disease or even building electronics.

It doesn't take a rocket scientist to make a lot of money, according to new research.

A nationwide study found that people of below average intelligence were, overall, just about as wealthy as those in similar circumstances but with higher scores on an IQ test.

Furthermore, a number of extremely intelligent people stated they had gotten themselves into financial difficulty.

"People don't become rich just because they are smart," said Jay Zagorsky, author of the study and a research scientist at Ohio State University 's Center for Human Resource Research.

Obese and overweight children increase their food intake by more than 100% after watching food advertisements on television; a study by the University of Liverpool psychologists has shown.

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine—a future where advanced organ damage can be repaired by the body itself. In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people.

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.Smaller males on top of larger females.

The Spanish Aging Research Network (Red Nacional de Investigación del Envejecimiento), funded by Carlos III Health Institute and headed by professor Darío Acuña Castroviejo, from the University of Granada (Universidad de Granada []), is very near to achieving one of today's Science greatest goals: allowing humans to age in the best possible health conditions.

Europe is facing a “major health and social burden” as the obesity epidemic reaches crisis point, experts warned today.

Governments, whose health ministers have already signed the ‘European Charter’ pledging to halt the rise in obesity by 2015, must now back more intensive research programmes, and gear up to cope with the scale of the epidemic, which is damaging quality of life and reducing life expectancy.

Early menarche tends to be preceded by rapid infancy weight gain and is associated with increased childhood and adult obesity risk. As age at menarche is a heritable trait, we hypothesised that age at menarche in the mother may in turn predict her children's early growth and obesity risk.
