Wear-Resistant Diamond Coating Created By Sandia Scientists: Superhard Material Thickly Coats Metals, Plastics, Also Stands Alone

Sandia researchers develop a simple way to relieve internal stresses in amorphous diamond films, creating thick, stress-free coatings that are harder than known coatings. The coatings have also been used to create large-area free-standing membranes with desirable properties such as high hardness and low friction.

Mammography Quality Law Has National Implications

A new analysis found that Michigan's strict mammography regulations, enacted in 1989 and 1994, significantly improved the quality of mammograms without limiting access to cancer-screening procedures. The study suggests that federal mammography standards will also have positive results.

Weight Loss, Not Weight Gain, A Health Risk For Older Adults

A comprehensive study published in the American Journal of Public Health found that weight loss, not weight gain, is associated with higher mortality rates in seniors. Women with a body mass index of 20 or lower had a significantly higher mortality rate than others.

A Cloud Of Water In Interstellar Space

A team of U.S. astronomers has discovered a massive concentration of water vapor within a cloud of interstellar gas close to the Orion nebula, measuring 20 times larger than observed in other clouds. The high amount of water vapor could provide crucial clues about the origin of water in the solar system.
