Rockefeller scientists found six such people with high levels of the antibodies that inhibit HIV proliferation and keep it from invading new cells. Taking blood samples from these special few, the researchers isolated the antibodies and set about discovering how they work...

Instead, the body deploys many dozens of antibodies - the researchers cloned 502 antibodies from the six patients - and together they attack many different virus targets. Individually, each antibody may have little effect, but as a group - or even in lab-created packages of 20 to 50 antibodies - they seem to confer some protection against disease progression. "It's the first time that anybody's really looked at what the antibody response is," says senior investigator Michel Nussenzweig, head of the Rockefeller University's Laboratory of Molecular...
Meanwhile, the mountainous terrain and high altitudes of Afghanistan have led the Army to increasingly emphasize rapid delivery of anything that can lighten a soldier's load. As a result, the U.S. Army Infantry Center at Fort Benning, Ga., is experimenting with a 4,000-lb, six-wheeled semiautonomous, supply-carrying robot vehicle called the Squad Mission Support System (SMSS), which will likely head to the mountains of Afghanistan for testing sometime next year...
