Genome project finds the 'triggers' for E. coli illness
The newly completed genomic sequence of E. coli O157:H7 reveals how these potentially deadly bacteria are armed with a surprisingly wide range of genes that may trigger illness.

Penn's Head Injury Center receives $110,000 NFL charities grant to study long-term effects of concussions
Physical contact is a part of every football game, but few things can sideline an otherwise healthy athlete faster than a concussion.

Molecules inhibit HIV protease, could lead to new line of attack against AIDS
Researchers have identified a molecule that could provide a second line of attack against HIV, the virus that causes AIDS.

Sweetly smelling sewers
Stinking sewers could smell sweeter with regular squirts of bacteria.

USC hair dye study
Women who regularly color their hair with permanent hair dyes--as well as hair stylists who work with such chemicals--are at greater risk for bladder cancer, according to a study from researchers at the Keck School of Medicine of the University of Southern California.

Software designed to help identify criminals who write ransom notes, forge checks
Who wrote the Jon-Benet Ramsey ransom note? A computer program developed at the University at Buffalo that is 98 percent effective in determining authorship of handwritten documents soon may be able to assist in answering such questions.

Drunks can control their behaviour
Rowdy drinkers can't blame their bad behaviour on alcohol. Canadian researchers say that people who've been drinking can control their behaviour if offered a small reward, such as verbal approval.

Clinical study confirms single gene change in chloroquine-resistant malaria
A team of U.S. and African medical researchers has developed a molecular marker that can be used to diagnose individuals with and survey populations for malaria parasites that are resistant to the drug chloroquine.

A bizarre new predatory dinosaur unearthed on Madagascar
Fossilized remains of a small and bizarre predatory dinosaur were recently recovered on the island of Madagascar.

Horizontal strain critical to characterizing aquifer properties and to understanding land subsidence
To understand how subsidence and fissures result from pumping aquifers, scientists and engineers need to measure horizontal as well as vertical strain, geologists have now demonstrated.

New South Pole Station power plant, satellite link go online
Major construction projects to improve the electrical generating capacity and communications links at the National Science Foundation's Amundsen-Scott South Pole Station were completed this month, despite extreme weather conditions in Antarctica that have hampered cargo flights.

New group of microorganisms discovered in the open sea
Archaea, one of three separate domains of life on our planet, were undiscovered until 1970.

Study suggests Venus could have been wet planet
Researchers at Washington University in St. Louis, studying hydrous mineral decomposition rates at extreme temperatures, have concluded that hot and dry Venus may have been a wet planet in the past, like Earth and ancient Mars.

Common treatment for diabetic crisis in children may contribute to rare but often fatal complication
A common treatment for children in diabetic crisis should be abandoned in most cases because it appears to contribute to a rare but often-fatal complication known as cerebral edema.

Gene sequence of deadly E. coli reveals surprisingly dynamic genome
The just completed genome sequence of a deadly type of Escherichia coli bacteria suggests that the microbe frequently picks up new DNA from other bacteria and bacterial viruses, including genes that may help explain why this organism is exceptionally virulent and sometimes difficult to treat.

"Dutch Nobel Prize" for three researchers
The Netherlands Organization for Scientific Research, NWO, has announced the names of the three researchers who are to receive an NWO/SPINOZA Award for 2000.

U.S. scientists, colleagues solve volcanic mystery, learn tears occur in vast plates
Working on volcanoes in the remote province of Kamchatka in easternmost Russia, U.S., Russian and German geologists believe they have solved a long-standing mystery about volcanoes ringing the Pacific Ocean.
