LIFE SCIENCES BY BERNARD DIXON European Editorial Offices The Scientist Uxbrldge, U.K. " Positron emission tomography studies in 20 Swedish army officer cadets have revealed metabolic changes in the same regions of the brain during both tactile learning and tactile recognition. This exciting glimpse of brain metabolism accompanying conscious activity appears in a new journal launched by the European Neurosciences Association and designed to interest the entire universe of neuroscientists, fro

Likening his discovery to a paleontologist unearthing a new dinosaur species, Vladimir Kapitonov, a staff scientist at the Genetic Information Research Institute, recently revealed a new class of transposable elements in eukaryotes. These jumping genes use rolling circle replication--an ancient process characteristic of some plasmid replication in bacteria--to copy and insert itself throughout entire genomes (V.V. Kapitonov, J. Jurka, "Rolling circle transposons in eukaryotes," Proceedings of th

The Human Genome Project's discovery1 that the human body runs on an instruction manual of a mere 35,000 or so genes--compared to the worm's 19,000, the fruit fly's 13,000, and the tiny mustard relative Arabidopsis thaliana's 25,000--placed humanity on an even playing field with these other, supposedly simpler, organisms. It was a humbling experience, but humility quickly gave way to awe with the realization that the human genome might encode 100,000 to 200,000 proteins. Scientists base this num

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b

Swiss anthropologist Jeremy Narby counts himself among the relatively thin ranks of scientists willing to publicly announce their conviction that nature is "minded," that an intelligence lies behind the development of life. Such a position is heresy to the prevailing scientific view of naturalism, which holds that nature is self-sufficient and the result of undirected processes. These two differing viewpoints usually are framed in the context of a debate between theology and science--creationis
