...caller reported that cash was stolen from his wallet at the Malkin Athletic Center. The wallet had been in a secured locker, but the lock had been cut off. The responding officer filed a formal report...
...question, of course, is how. Initially, California's hastily implemented deregulation wouldn't even permit utilities to hedge their bets with long-term fixed contracts--a key ingredient of successful deregulation efforts in states such as Pennsylvania and Maryland. The fear, ironically, was that they would lock in a high sale price today at the risk of missing out on a lower one tomorrow. Instead, they've had to pay top dollar on the daily spot market...
...type of immune cell known as CD4. You can think of these points of entry as windows or doors into the cell; in order to get inside without destroying the cell (which has machinery the virus needs to reproduce itself), HIV has to find and pick the lock. To do this, it links simultaneously to an adjacent section on CD4 known as a cytokine receptor. Once the virus has bound to both CD4 and the cytokine, chemical changes take place that alter the structure of the cell's membrane, and the lock is "tripped." Fusion between the virus...
Other cancers are also being targeted. In July doctors at the University of North Carolina began trials of a breast-cancer vaccine based on bioengineered dendritic cells--rare white blood cells that act as scouts for the immune system. These lock onto a protein called HER-2/neu found in the tumors of a third of all breast cancers. At UCLA's Jonsson Cancer Center, researchers are working on a vaccine to treat brain cancer. Still other scientists are experimenting with vaccines for kidney, colon, pancreatic and ovarian cancer...

When used on larger jets such as a Boeing 747, the devices are installed on each engine so that missiles don't have a chance to establish a heat lock. The Gulfstream's rear-mounted engines require only a single unit...
