Fish may show how nature diversifies
HHMI researchers report the creation of a genetic map of the threespine stickleback fish that will make it possible for researchers to tie behavioral, ecological, morphological and physiological differences among the various species of sticklebacks to changes in the genome.

Trauma survivors losing less sleep than they think
Dr. Peretz Lavie of the Technion-Israel Institute of Technology reports that many trauma survivors sleep better than they think they do; leaving traumatic memories behind may be more effective for a good night's sleep; treating sleep disorders as an independent entity could prevent severe psychological conditions; and that many suffering from sleep problems after Sept 11 will have only transient symptoms, a normal reaction to traumatic events.

Scientists describe structures of protein molecules that enable two-way signaling between cells
Two neuroscientists from UT Southwestern Medical Center at Dallas collaborated with cancer investigators in New York and Australia to determine the structures of protein molecules that bind together to initiate two-way signaling between human cells.

Cardiac stress tests may indicate if blockages will recur after angioplasty with stent implant
A nuclear cardiac stress test administered shortly after a coronary angioplasty with stent implantation may give important clues to whether the procedure was successful or whether the patient will experience restenosis (recurrent narrowing of the arteries), requiring additional procedures or surgery.

Gasoline additive interferes with alcohol breath analyzers
Very high exposure to a gasoline additive, methyl tert-butyl ether (MTBE), can trigger a false positive reading on some breath-alcohol analyzers used by law enforcement officers to determine legal intoxication, according to a study from the Johns Hopkins Bloomberg School of Public Health.

Voting via the Internet raises social and technical issues
Elections of the future may be more convenient, accurate and faster for both voters and elections officials if researchers can improve the technology for voting via the Internet.

UF study: Grandparents celebrated instead of reviled in children's lit
The golden years have entered a golden age in children's books, which now overwhelmingly portray grandparents as upbeat, independent and wise, a University of Florida study shows.

Massachusetts leads the nation in unemployment growth
Northeastern University's Center for Labor Market Studies newest report reveals that the Bay State leads the nation in its rate of unemployment growth (83 percent more than last year) and reveals that those who have lost their jobs are, by and large, highly educated professionals, unlike the recession of the early 90s which found many with only high school degrees or less out of a job.

IBM's test-tube quantum computer makes history
Scientists at IBM's Almaden Research Center have performed the world's most complicated quantum-computer calculation to date.

Southern ocean iron may have come from the depths, not the atmosphere, researchers conclude
Two researchers from Indiana University - Purdue University Indianapolis (IUPUI) cast doubt on dust as the principal source of iron and propose an alternative source of iron in the Southern Ocean.

From criminology to seeking a cure for cancer - today's DNA analytical tools make possible what was once unthinkable
Using the latest DNA analysis techniques, Fred Hutchinson Cancer Research Center scientists have discovered that some tissue-type mismatches are permissible in bone-marrow transplantation to treat leukemia, opening doors for many people who are unable to donors.

Drunken driving costs and risk measured more accurately by economists
Drunk drivers are at least 13 times more likely to cause a fatal crash than sober drivers, according to a new study by Steven Levitt, Professor of Economics at the University of Chicago and Jack Porter, Professor of Economics at Harvard University.
