A study by UPMC researchers found that serotonin receptors in the brain decline by 55% with age, even after accounting for normal aging changes. This decline may contribute to the development of depression and Alzheimer's disease, highlighting the need for effective treatments.
Researchers have identified a critical nicotinic receptor in the brain that may contribute to the development of epilepsy, Alzheimer
Charles Rick's half-century of research at UC Davis forged a fundamental understanding of tomato genetics. He identified 42 disease-resistance genes and bred them into commercial varieties, benefiting almost every other vegetable crop worldwide.
A recent Virginia Tech study reveals that students in technology-enriched courses reported more active engagement with coursework, investing more of their own time. Faculty members also reported a change in their role from one-way information dispensers to facilitators for learning.
A recent study found that women with unplanned pregnancies are less likely to breastfeed, which can lead to poorer health outcomes for their children. The research, published in the American Journal of Public Health, suggests that doctors may not be adequately addressing the issue.
Science's Next Wave is creating a fellowship database with funding from HHMI. The site will feature profiles of selected foundations and other funding organizations, providing crucial information for young scientists. The new database will debut in early 1998.
Research findings suggest that ferrets may be observed for a period of 10 days after biting humans, allowing for potential quarantine rather than euthanasia. The change in regulations has significant implications for the ferret community and public health veterinarians.
The American Association for the Advancement of Science (AAAS) has been awarded a $825,000 grant from the Howard Hughes Medical Institute to create a 'one-stop shopping' site for young scientists. The site will feature an extensive database on fellowships, graduate programs, job openings and other opportunities.
The article presents data on crash rates and driver experience to argue in favor of adopting graduated licensing systems. An ideal system starts learner's process at age 16, limits graduation until age 18, and restricts late-night driving.
Lee R. Berger receives the top prize for his groundbreaking discoveries in southern Africa, including the oldest known footprints of an anatomically modern human dating back 117,000 years. He aims to piece together data on the environment that spawned early humans.
Researchers at PPPL and USDA's ERRC are collaborating on a $120,000 project to develop radio frequency pasteurization methods. The new techniques use RF waves and microwave heating to effectively pasteurize raw liquid foods like eggs and milk without overheating them.
Researchers found that using rapid diagnostic methods for M. tuberculosis can decrease diagnosis time from 38.5 to 23 days, time to therapy from 6.6 to 2.0 days, and mortality by 22-33%. This also reduces healthcare costs per patient.
