A new study shows that juvenile delinquents sentenced to either a juvenile retreat, probation or unsupervised community service were seven times more likely to commit criminal acts as adults than youngsters from the control group who managed to avoid the

One quarter of children who sleep fewer than 10 hours a night become overweight by age 6, according to new research. The research team analyzed a sample of 1,138 children and found: 26 percent of kids who didn't sleep enough

All of us have experienced being in a new place and feeling certain that we have been there before. A new report published in Current Directions in Psychological Science describes recent findings about deja vu, including the many similarities that

A study is under way at Rush University Medical Center using a small, soft-patch device made of a Gore-tex-type material -- often used to make durable outerwear -- to close a common hole found in the heart called a patent

A very low risk of complication is associated with a routine test that determines whether a brain aneurysm treated with endovascular coiling has started to recur, a study has shown.

New research in mice suggests that high levels of social support may provide some protection against strokes by reducing the amount of damaging inflammation in the brain. Researchers found that male mice that lived with a female partner before and

With millions of baby boomers entering late adulthood, the number of patients with Alzheimer's disease is expected to drastically rise over the next several decades. A team of national researchers, has developed a rapid screening test to detect mild cognitive

Alex Martin placed rats in a partially echo-free, sound-proof chamber and simultaneously played two types of sounds: Gaussian sound (containing all frequencies) of 25 decibels and a pure sound (made up of one frequency). He found that auditory neurons respond

Researchers have discovered how to train the brain of athletes to improve their overall athletic performance.

What makes residents of certain states or countries more likely to consume more alcohol? According to a new study in the Journal of Consumer Research, high levels of individualism lead to more problem drinking.

A new study provides the first evidence of a link between alcohol-industry sponsorship and hazardous drinking among sportspeople.

When picking through a basket of fruit, it doesn't seem very difficult to recognize a green pear from a green apple. This is easy, thanks to "feature binding" -- a process by which our brain combines all of the specific

scientists at the University of Liverpool have found.

Archaeologists in southeastern Turkey have discovered an Iron Age chiseled stone slab that provides the first written evidence in the region that people believed the soul was separate from the body.

Historians explain that the current version of Thanksgiving was created by a journalistic crusader, and would have been unrecognizable to the Pilgrims it supposedly honors.

A scheme of mechanics, called `supmech', is developed integratingnoncommutative probability and noncommutative symplectic geometry in analgebraic framework -- a unification of the type envisaged in Hilbert's sixthproblem. The scheme operates essentially as noncommutative Hamiltonianmechanics incorporating the extra condition that the

This work develops the correspondence between orbifolds and free fermionmodels. A complete classification is obtained for orbifolds X/G with X theproduct of three elliptic curves and G an abelian extension of a group (Z_2)^2of twists acting on X. Each such

Variational principles for magnetohydrodynamics were introduced by previousauthors both in Lagrangian and Eulerian form. In a previous work Yahalom &Lynden-Bell introduced a simpler Eulerian variational principles from which allthe relevant equations of magnetohydrodynamics can be derived. The variationalprinciple was given

Let G be a compactly generated locally compact group and let $U$ be a compactgenerating set. We prove that if G has polynomial growth, then (U^n) is aFolner sequence: that is, the volume of the boundary of U^n divided by

We study the geometry of nonrelatively hyperbolic groups. Generalizing aresult of Schwartz, any quasi-isometric image of a non-relatively hyperbolicspace in a relatively hyperbolic space is contained in a bounded neighborhoodof a single peripheral subgroup. This implies that a group being
