Hubble images may shed light on importance of novae in galactic evolution
New Hubble Space Telescope NICMOS images show gas shells ejected into space at regular intervals by an unusual type of white dwarf star, possibly revealing important information about the role novae play in the evolution of our galaxy, including the distribution of heavier elements and the development of planetary systems.

Advance reported in search for skin cancer treatment
In the search for skin cancer treatments, chemists at the University of Notre Dame have constructed a computer model of the chemical structure of an enzyme that many organisms use to repair DNA damaged by ultraviolet light.

Scientists identify molecular source of friction
Exactly 300 years after Guillaume Amontons produced the classic laws of friction, physicists have explained why Amontons' equations explain static friction so precisely.

Jet Stream Studied In West African Drought
The two jet streams that flow over West Africa during the summer months may contribute to the extended drought that has plagued this already semi-arid area, according to Penn State researchers.

Can Doppler weather radar detect turbulence? Three aircraft head into Colorado storms to find out
Starting June 2, the National Center for Atmospheric Research is helping guide three research aircraft into Colorado thunderstorms to test how well an airborne Doppler weather radar can detect convective turbulence.

Genetic testing and modified diets may save babies born with genetic defect
Genetic testing and dietary modification may save the lives of children born with a defect in the gene controlling fatty acid breakdown, a Wake Forest University Baptist Medical Center physician reported in the June 3 issue of the New England Journal of Medicine.

An artificially intelligent tutoring system that semi- automates team training methods has been successfully demonstrated in a Navy laboratory and will be studied further at the AEGIS Training and Readiness Center in Dahlgren, Va.

Teaching emotional control could be the best Father's Day present
Perhaps the best present fathers could give in a society concerned with growing teen-age violence is emotional control, a skill scientists believe fathers help foster in powerful ways, says University of Washington Psychologist John Gottman who is participating in a panel on emotional regulation at the American Psychological Society's annual meeting in Denver.

NIAAA-led study verifies environment-dependent behavioral variation in genetically identical mice
John Crabbe, Ph.D., Portland Veterans Affairs Medical Center and Oregon Health Sciences University, Department of Behavioral Neuroscience, with colleagues in three widely separated laboratories report in this week's Science that animals with the same genes performed differently on a variety of behavioral tests depending on the animals' location.
