Researchers at Schering-Plough Research Institute have made the first atomic view of a promising new class of cancer-fighting drugs. The discovery may lead to faster, better refinement of the drugs and the development of more potent, less toxic treatments.
A team of astronomers has discovered a unique cluster of young stars, approximately 8 million years old, located 97 parsecs from Earth. The cluster, centered around eta Chamaeleon, is one of the nearest to our planet and exhibits unusual characteristics.
CHESS is building a major addition dubbed G-Line, which will produce X-rays at intensity levels five to 50 times greater than existing lines. The new facility will support 80 percent of research time for Cornell personnel.
A new Mayo Clinic study finds that parkinsonism affects 7.5% of the population, with men twice as likely to develop it as women. The study reveals that Parkinson's disease accounts for only 42% of all parkinsonism cases.
Eating a diet high in cereal fiber can help reduce a woman's risk of heart attack, with the highest fiber consumers having a 23% reduced risk of heart disease. The study also found that smoking less, exercising more and eating foods high in vitamins and minerals were associated with higher fiber intake.
Research reveals that showing pictures of admired individuals from marginalized groups can significantly decrease unconscious prejudice. Exposure to images of admired blacks reduced levels of unconscious prejudice by one-third, while exposure to images of admired elderly people lowered ageism by a similar amount.
A new case-control study suggests that high levels of serum ferritin are associated with an increased risk of heart attacks in elderly individuals with other cardiovascular risk factors. Consuming iron-rich foods like red meat can contribute to elevated serum ferritin levels.
A meta-analysis of formerly obese individuals who lost weight found that their resting metabolic rate decreased, explaining why dieters struggle to maintain weight loss. This decrease in metabolism may be a key factor contributing to the difficulty in keeping excess weight off.
A study published in the American Journal of Clinical Nutrition found that consuming a moderate-fat diet rich in plant oils reduced LDL cholesterol levels by 25% in hyperlipidemic men. The specific type of plant oil used in the study was found to have a significant impact on improving cholesterol profiles.
A new study found that enhanced external counterpulsation (EECP) significantly reduces angina pain in patients. The treatment, which involves inflating cuffs on the legs during heartbeats, improves cardiac blood flow and pumping efficiency.
The long-term study found that orlistat helped successful dieters keep weight off. The accompanying editorials suggest that orlistat's benefits are modest.
Researchers found that spotted antbirds in a Panama rainforest increase testosterone levels to boost aggression against invaders, even during the off-season. This finding has implications for understanding aggression regulation in humans and may reveal insights into physiological parameters.
A Phase I study published in Circulation demonstrates that ENBREL improves quality of life scores and increases functional status in patients with advanced heart failure. The study found no significant adverse effects from ENBREL treatment, suggesting a potential therapeutic benefit for chronic heart failure patients.
Researchers observe highly nonexponential folding times in yeast phosphoglycerate kinase and ubiquitin mutant proteins. Downhill folding theory suggests a protein encounters temporary structures en route to its native state.
A new study published in American Journal of Clinical Nutrition found that restricting children's access to certain foods can actually encourage overeating. By removing access to desired foods, children are more likely to consume those same foods, leading to increased intake.
Researchers found that reading a story about a fictitious childhood experience can change people's memories, with opposite-sex stories affecting belief more strongly. The study used a questionnaire to screen participants and then asked them to read a short story with few details.
Yucca Mountain's long-term hydrologic stability makes it a potential site for storing nuclear waste. Calcite and opal deposits indicate minimal water flow into the mountain's cavities.
Researchers have uncovered clues to the cause, timing and evolution of the massive East Asian summer monsoon. The study found a connection between the disastrous 1998 Yangtze River flood and the timing and strength of the summer monsoon.
Gene therapy's concern about viral DNA insertion into gametes is unfounded, as naturally occurring insertions in sperm cells are 100 times more common than the FDA limit. Researchers estimate that 1 individual in every 8 carries a new retrotransposon insertion.
Scientists measure solar wind gusts that squeeze the Earth's magnetosphere, triggering brightening in the aurora borealis. This phenomenon can lead to global magnetic storms, potentially disrupting communications and power supplies.
Climate models project a 23-30% decline in mountain snowpack by 2025, and up to 61% by 2095. This could drastically alter hydrology and water resource management in the region.
A new Hubble image captures the entire stellar life cycle in a single photograph, showcasing various stages of star formation and evolution. The galaxy NGC 3603 is home to multiple starburst clusters, young massive stars, and a blue supergiant nearing its supernova fate.
