Bacteria in space, beware. New technology to monitor and identify bacteria is in the works.

Dr. George E. Fox and Dr. Richard Willson, researchers on the National Space Biomedical Research Institute’s immunology and infection team, have developed a new technology to characterize unknown bacteria. Its immediate application will be for identifying bacteria in space, but it will eventually aid in diagnosing medical conditions and detecting biological hazards on Earth.

A new molecular tag discovered by scientists at The University of Texas M. D. Anderson Cancer Center may help doctors decide which breast cancer patients need more aggressive treatment and which can forego the potentially toxic course of chemotherapy.

Khandan Keyomarsi, Ph.D., associate professor in experimental radiation at M. D. Anderson, and her colleagues report in the November 14, 2002, issue of the New England Journal of Medicine that high levels of a protein called cyclin E are close

El Niño, the pattern that can wreak havoc on climate conditions around the world, is like a beacon, pulsating through time on a 2,000 year cycle, according to a new study by scientists from Syracuse University, Syracuse, N.Y.; Union College, Schenectady, N.Y., and from the NOAA Paleoclimatology Program, Boulder, Colo., that is being publis

Scientists have shown, for the first time, that changes in a large-scale climate system can synchronize population fluctuations in multiple mammal species across a continent-scale region. The study, to be published in the 14 November 2002 issue of the journal Nature, compares long-term data on the climate system known as the North Atlantic Oscillation with long-term data from Greenland on the population dynamics of caribou and muskoxen, which are large mammals adapted to breeding in the Arctic.

A step to further understanding of the process whereby genes are turned on and off in living organisms has been achieved by a team of researchers at the Hebrew University-Hadassah Medical School. Understanding of this process has substantial consequences for furthering the use of medical genetic engineering to grow new tissue to replace damaged or defective organs or to halt the growth of undesirable tumors.

The achievement is described in an article in the current issue of Nature magazine

At best, a yachtsman far out to sea experiences an exhilarating solitude to equal any space traveller. But too much isolation at sea can give rise to loneliness, disorientation and multiple dangers.

A new ESA-developed technology enables boat crews to check their positions, stay in constant contact with shore, receive urgent emergency warnings, and enable friends and family to remotely track them on the internet.
If a boat becomes dangerously water-logged or its power system is o
