n that contained six to 34 percent heroin. The scientists tested the samples using the new analytical method, called Diffuse Reflectance Near-Infrared Spectroscopy (DR-NIR). It involves shooting a beam of infrared light into a sample to determine its chemical composition based on the wavelength of light emitted. The method quickly and accurately determined the chemical content of the samples without any prior sample preparation, the scientists say. MTS

Key proteins identified in the quest for male contraceptive
Journal of Proteome Research

In an advance toward a long-sought new male contraceptive, researchers in China have identified key proteins in men that suppress production of sperm and could become new targets for a future male birth control pill. Their study is scheduled for the October 3 issue of ACS' monthly Journal of Proteome Research.

Jiahao Sha and colleagues point out that scientists do not understand one effect of the male sex hormone, testosterone how injections of the hormone suppress production of sperm. Building on a previous study showing almost total sperm suppression with an injectable testosterone combined with a synthetic hormone called levonorgestrel (LNG), the researchers sought new insights into how hormones affect sperm-producing cells in the testicles.

In a new study on men, they found that testosterone combined
