mussels in and around New York's Lake George. The lake lies near Lake Champlain and the Hudson River, which have large "mussel beaches." The data collected also could provide vital information on natural factors, such as pH and calcium levels, that might daunt colonization, says Nierzwicki-Bauer. FAX (518) 277-2825.

Computer-designed drugs take on cancer

BioNumerik Pharmaceuticals will enter a beta site agreement for new supercomputer systems from Cray Research, Inc. designed to speed the development of cancer and heart-disease drugs. BioNumerik will use the supercomputers to optimize its proprietary computer-aided, drug-design software. "This trial is different from previous rational drug design methods, where computers have been used to analyze, but not optimize existing substances for potential use as drugs," says BioNumerik CEO Dr. Fred Hausheer. Current work includes preclinical development of several drugs aimed at treating lung, breast, colon, prostate, and pancreas cancers. FAX (210) 614-1701.

Artificial intelligence outmatches physicians

A computer has taught itself to predict if a patient has prostate cancer--before a surgeon performs a biopsy. The program also predicts whether a patient will experience disease recurrence. That's the prognosis of investigators at the Washington University School of Medicine in St. Louis. In a pilot study, the investigators entered medical information into a computer about patients, with the outcome already known. The artificial intelligence system predicted prostate biopsy results with 87% accuracy, and prostate cancer recurrence with 90% accuracy. Physician judgment, largely based on prostate cancer screening tests, can predict biopsy results with only 35% accuracy. FAX Susan M. Killenberg at (314) 935-4259.

Researchers 'super express' attention shift

A team at the Cambridge Basic Research (CBR) facility has found a way to dramatically reduce the time it takes a person to shift attention from one thing to another. Team leader Dr. Shinsuke Shimojo, a professor at the University of Tokyo and visiting CBR scientist, discovered the "Super Express Attentional Shift." It involves having people shift their attention from one point to another as soon as the second point appears. It can happen, for instance, when a warning light goes on. Such conditions, according to Shimojo, allow people to shift their attention up to 40% faster than normal. The discovery could have applications in the design of intelligent displays.

CAD/CAM, CAE software revenues to hit $4 billion

CAD/CAM, CAE software revenues should top $4.1 billion in 1994, according to Daratech, Inc. That figure represents a growth of 8.5% over 1993. Parametric Technology, Cadence Design Systems, Synopsys, Autodesk, and other growth leaders account for the strong revenue showing, according to the forecast. "Parametric's unique technological vision is finding worldwide acceptance, as more than half of the company's 306 new customers added during the quarter ended September 30, 1994 are outside the U.S.," the report notes.
