Scientists have found evidence that the gassy halo of Halley's comet contains tiny chains of formaldehyde molecules that may be older than the solar system. The evidence comes from data collected by the Giotto spacecraft as it flew by the comet in March, 1986, according to two papers in the current issue of Science magazine. Comets are considered remnants of the gas and dust that condensed to create the sun and its planets.

AIDS "now ranks as the most serious epidemic of the last 50 years," an international group of researchers declared in a report that urges global cooperation to head off the spread of the deadly acquired immune deficiency syndrome. Noting that several million people around the world now are infected with the AIDS virus, the researchers called for "a major international commitment, not only in terms of providing financial help but also in providing scientific, educational and technical assistance."

In Atlanta and certain other southern cities, trees may contribute more hydrocarbons to the formation of photochemical smog than do cars and factories, according to computer modeling studies conducted by researchers at the Georgia Institute of Technology. These emissions may doom the Environmental Protection Agency's attempt to control pollution by restricting release of man-made hydrocarbons, the researchers said.

More than a billion tons of carbon emitted into the atmosphere each year in the form of carbon dioxide cannot be accounted for but is probably being absorbed by land masses in the Northern Hemisphere, researchers from the National Oceanic and Atmospheric Administration reported last week in Science magazine. Release of carbon dioxide into the atmosphere is believed to be contributing to a warming of the planet through the greenhouse effect, which traps heat at the Earth's surface.

Arthur Walker, 64, a Stanford physics professor whose work helped scientists investigate mysteries of the sun, died at his Stanford home April 29 of cancer. Using X-ray and thin-film telescopes, Walker photographed the sun's corona, or outermost atmosphere, obtaining images that were printed on the cover of the Sept. 30, 1988, Science magazine.

The brains of experienced meditators appear to be fitter, more disciplined and more "on task" than do the brains of those trying out meditation for the first time. And the differences between the two groups are evident not only during meditation, when brain scans detect a pattern of better control over the wandering mind among experienced meditators, but when the mind is allowed to wander freely. Those insights emerge from a study to be published next week in the Proceedings of the National Academy of Sciences, which looked at two groups: highly experienced meditators and meditation novices, and compared the operations of the " Default Mode Network " -- a newly identified cluster of brain regions that go to work when our brains appear to be "offline.

In its 2007 report on the effects of global warming, the Intergovernmental Panel on Climate Change stated that glaciers could vanish from the Himalayas by 2035. As has since been widely reported, with ill-disguised glee by many blogs and right-wing news outlets, this was a blunder. The prediction didn't come from a peer-reviewed scientific study but from a prominent Indian glacier expert who was quoted in a British popular science magazine -- and who now claims he never gave such a date.

LAST SPRING, AN AUDIENCE COMposed mostly of earnest-looking young female students gathered in a small auditorium to hear a panel discussion entitled "Women Scientists at Work: Opportunities, Obstacles and Challenges." Among the speakers were a bookish-looking research physicist, a computer-engineering researcher and a pregnant professor of civil engineering whose faded blue maternity smock couldn't conceal her third trimester fullness.

Science 86, the award-winning popular science magazine that helped pioneer a trend toward glossy, technical publications for lay readers, will cease publication with its current issue and sell some assets to Time Inc., it was announced Friday. The American Assn. for the Advancement of Science, which began publishing the magazine as Science 80 in the fall of 1979, said it is selling its Science 86 subscriber list and licensing the publication's name to Time for two years as part of the deal.
