Biologists have discovered that certain proteins vital to life and long thought to be immobilized within the sack-like cell structures where they function instead move freely and rapidly. The finding, reported in the Aug. 9

Hibernation: The Opposite of Sleep?
Is animal hibernation really a blissful, season-long slumber, or is it more like a months-long bout with insomnia? Brian Barnes reports in the Sept/Oct issue of The Sciences magazine on the hibernation patterns of arctic ground squirrels, which appear to go through something more closely resembling an icy stupor rather than a restful sleep

Teachers Capture the Excitement of Martian Meteorite with Science 'Toolkit'

A Gene Involved in Regulating Longevity in Worms May Provide a Clue to Human Aging
Discovery of a mutant gene involved in the regulation of longevity of a primitive worm, C. elegans, may provide a clue as to how humans age. Normal development and longevity in the worm C. elegans are regulated by the age-1 gene. Lack of age- 1 activity in adult worms, due to mutations in the age-1 gene, results in a doubling of adult life span.

Cat Scratch Disease Bacteria Transmitted by Fleas
While a cat scratch may be the most common vehicle for transmitting cat scratch disease from felines to humans, the common cat flea is probably the most frequent way of transmitting the infection between cats, say researchers at the University of California, San Francisco

Bee Sting Treatment Should Emphasize Speed, Not Method Of Removal
Immediate treatment of bee stings -- one of the most common insect-caused injuries to humans -- should emphasize quick removal of the sting, rather than the method by which the sting is removed, according to entomologists at Penn State and the University of California, Riverside.
