When mice choose mates, experience counts

Choosing a mate is a big decision. And, at least for mice, it's one that is best made with input from one's peers. In a series of experiments designed help scientists understand the brain chemicals that guide mate selection, Pfaff and his colleagues exposed female mice to odors of either a male mouse alone or a male mouse with a female. The females consistently preferred the scent of males...

Female pronghorns choose mate based on substance as well as show

When a female animal compares males to choose a mate, she can't order a laboratory genetic screen for each suitor. Instead, she has to rely on external cues that may indicate genetic quality. Until now, biologists have focused on elaborate ornaments, such as the peacock's tail, as cues that females might use. The thorny problem has been to explain how the correlation between male genetic q...

T for two: Scientists show how immune system chooses best way to fight infection

Genes and biomarkers that allow doctors to choose the right therapy for the right patient

Genetic and epigenetic variations ensure that no two people are exactly alike, and the same holds true for any two cancers. Now, researchers have the tools and the knowledge to help predict how individuals will respond to cancer therapies, enabling them to create more effective therapies for individual cancers ?personalized medicine. At the 2007 Annual Meeting of the American Association for Can...
