CHANGE ABOVE - Smoke and other aerosol particles can encourage or discourage cloud formation, depending on the conditions, and a new model shows how these two processes produce a joint effect on climate. Ilan Koren and colleagues at the Weizmann Institute in Israel analyzed a variety of aerosol samples from the atmosphere above the Amazon to show how these two pathways interact. They say their study should help researchers improve their predictions of how air pollution and naturally occurring aerosols may influence climate changeInformation can be found in the Aug 15 issue of Science.

Many studies have shown that women seem to prefer the scent of mates who have MHCs dissimilar to their own, a ... (Full article: 561 words)
