The HIV virus attacks white blood cells by latching onto a protein on their surface. People without that protein are immune from AIDS. Using that knowledge, scientists in Pennsylvania have figured out how to genetically manipulate mice so they, too, have the immunity.

The procedure has not yet been tested on humans. If it does work, it wouldn’t cure the disease, but it could let infected persons live healthier lives with the virus.

Yet another promising line of attack against cancer: doctors in Seattle have treated a man with advanced skin cancer by cloning his white blood cells – the part of the human immune system that fights infection – and injecting them into his tumors. The cancer has gone away and not returned for two years.
