Acoustic technique could disinfect medical instruments without heat or harsh chemicals
An acoustic phenomenon previously studied for its effects on submarines could be the basis for an improved disinfection technique able to rapidly kill microorganisms on medical instruments without high temperatures or harsh chemicals.

Family routines and rituals may improve family relationships and health
Family routines and rituals are important to the health and well-being of today's families trying to meet the busy demands of juggling work and home, according to a review of the research over the past 50 years.

INEEL geoscientist to present NAPL contaminant modeling advance at AGU Meeting
By modifying the mathematical theory describing the relationship between permeability, saturation, and pressure in a multiple fluid system, INEEL researchers can now more accurately predict the movement of non-aqueous phase liquid (NAPL) contaminants in the subsurface.

Jewels that may help explain behavioral disorders found among 'junk' DNA
Scientists have been looking for genes to explain behavioral disorders for 20 years without much success.

A new approach holds promise for reducing cocaine craving
New understanding of the changes in brain chemistry caused by chronic cocaine use has suggested a novel treatment that could reduce the intense craving that forms the core of cocaine addiction.

The genetic basis for caffeine-induced anxiety discovered
In one of the first studies to identify the genetic basis for behavior differences in the individual reaction to a drug, Harriet de Wit of the University of Chicago reported that individuals who have two linked genetic variations in an adenosine receptor gene are far more likely to end up biting their nails following a jolt of caffeine than those who don't.

Scientists discover gene 'signature' for tumor's tendency to spread
Researchers at Dana-Farber Cancer Institute and the Whitehead Institute have discovered a pattern of genetic activity in several types of primary tumors that appears to predict the likelihood that they will spread, or metastasize, to other parts of the body.
