Himalyan ice cores reveal climate warming, catastrophic drought
Ice cores drilled through a glacier four miles up in the Himalayan Mountains have yielded a highly detailed record of the last 1,000 years of earth's climate in the high Tibetan Plateau.

Women with epilepsy are poorly managed during pregnancy
Guidelines for the management of women with epilepsy are not being followed, according to a study in this week's BMJ.

Europeans will adjust to global warming but will still die of cold
Heat related deaths start at higher temperatures in hot regions of Europe compared to cold regions, suggesting that people have adjusted successfully to differences in summer temperatures across Europe, and can be expected to adjust to the global warming predicted in the next 50 years, according to a study in this week's BMJ.

Newly revised recommendations affirm medicine
The American College of Rheumatology has released newly revised 'Recommendations for the Medical Management of Osteoarthritis of the Hip and Knee: 2000 Update' in the September edition of Arthritis and Rheumatism.

New IIASA research challenges Kyoto Protocol
IIASA recently released its latest research study, Full Carbon Account for Russia, which shows serious flaws in the Kyoto Protocol, a strategy adopted at the Earth Summit in Rio in 1992 as the way to control greenhouse gases and curb global warming.

Progress on the molecular basis of mental illness in children
Six articles in the current issue of Molecular Psychiatry (Nature Publishing Group) present a series of novel and highly interesting findings on the molecular basis of mental disorders in children.

Onset of forearm pain can be predicted
The concept that forearm pain is caused purely by repetitive movements of the arms or wrists, particularly in the workplace, is called into question in this week's BMJ.

Paralyzed worms add pieces to the puzzle of RNA interference
Using genetically altered strains of the roundworm C. elegans, HHMI scientists have revealed some of the genetic components responsible for a still-mysterious cellular process called RNA interference (RNAi)--in which double- stranded RNA triggers the degradation of a homologous messenger RNA.

OHSU researchers reveal how bacteria crawl on surfaces
OHSU scientists have discovered how bacteria that cause diseases such as E. coli infections, diarrhea, meningitis, and gonorrhea are able to move over human mucosal surfaces to cause infection.

Researchers discover new oceanic bacterial photopigment that converts light into biochemical energy
Microbiologists from the Monterey Bay Aquarium Research Institute report the discovery of a novel light-absorbing pigment found in oceanic bacteria.

Biological marker associated with depression in children uncovered by University of Pittsburgh researchers
Researchers at the University of Pittsburgh School of Medicine have been able to demonstrate for the first time a biological change in children at risk for major depression before they develop the illness.

Screening leads to substantial reduction in breast cancer deaths
The introduction of an NHS breast screening programme, along with improvements in treatment for breast cancer, led to a 21% reduction in breast cancer deaths in England and Wales between 1990 and 1998, finds a study in this week's BMJ.

Jefferson scientists describe new, potentially deadly immune syndrome in AIDS patients
Scientists at Jefferson Medical College have characterized a medical paradox: A new, potentially deadly 'immune reconstitution syndrome' in AIDS patients.

Study shows how drug blocks leukemia-triggering enzyme
HHMI researchers have found how the anti-leukemia compound STI-571 is able to inhibit a runaway protein switch that spurs blood cells toward a cancerous state.

Science: Prion proteins may signal trouble -- literally
A harmless form of the scrapie prion -- an abnormally folded protein that leads to brain-degenerating diseases in humans, sheep, and cows -- may help regulate nerve-cell functions through cellular signaling, a new Science study shows.
