...scientists may have the key to warding off the sniffles. Reporting in the journal Cell last week, two separate research teams announced the discovery of a cell molecule to which rhinoviruses attach themselves. When the cold viruses bind to the molecule, known as the ICAM-1 receptor, they infect the cell...
Ranchers claim that the bison, in addition to damaging fences and depleting food needed by cattle, can infect their herds with brucellosis, a disease that causes cows to abort their calves -- though there are no documented cases of such bison-to-cattle infections. More than 200 bison have been bagged so far this season. Government biologists say the toll will not deplete the park's bison population of 2,700, but animal-rights groups want federal authorities to provide feeding spots for the animals inside the park. "The object is to put a head on somebody's wall," says...
...They're calling [Sudduth and Graham] in not necessarily for their expertise, I think, but to establish whether Morris had the intent to infect federal computers, or was he reckless enough [to allow it and was he expert enough," said George-town law student and technology writer Robin A. Meltzer...
After a series of interviews with experts on computers and computer security, it appears that the virus spread itself in a three-step process, which transformed an innocent computer into one that could infect others--like a chain-letter scheme run on the most advanced circuitry...
Morris had accidentally instructed the computer to infect every 10th adjacent computer on the Internet instead of every 10,000th, according to Jeffrey I. Schiller, M.I.T. network manager. As a result, the virus tried to spread too quickly and multiple copies of the virus were sent to the same machines, eventually using too much memory and computer time, causing the systems to crash...
