Mayo Clinic Researchers Create 'Obedient Virus'; First Step To Use Measles Virus Against Cancer

...concern that the measles virus may be a little too promiscuous in its ability to infect both cancer cells and non-cancer cells, so we wanted to develop a method whereby we could retarget the virus to infect cancer cells only," says Dr. Russell. "And we succeeded." ...

While on trail of dioxin, scientists pinpoint cancer target of green tea

...orking on ways to block HSP90, which is known as a promiscuous chaperone protein because it binds to many different cells and receptors in the body.

Male chimpanzees prefer mating with old females

...at whereas chimpanzees participate in a relatively promiscuous mating system, humans form unusually long-term mating bonds, thereby making young females more valuable as mates with greater reproductive potential. The findings, reported by Martin Muller of Boston University and colleagues at Harvard University, a...
