Scientists have relieved pain in rats by dispatching molecular 'smart bombs' to selectively destroy certain nerve cells in the spinal cord, targeting faulty signaling by a small group of neurons. This approach targets just those nerve cells that send pain messages to the brain without causing side effects like morphine or surgery.
A new hearing test called wide-band reflectance could improve diagnosis of middle ear infections and other hearing disorders. The test uses softer sounds to trigger a middle ear reaction, allowing doctors to make a diagnosis without exposing patients to intense noise.
A University of Michigan study found that older Americans with depressive symptoms are at a higher risk of developing new diseases within two years, comparable to those who smoke. Physical limitations and multiple symptoms of depression also significantly increase the likelihood of developing new disease.
Researchers at Rice University have created a reversible molecular computer switch, which can represent ones and zeros in digital computing. The switch is made of molecules that are one million times smaller than traditional silicon-based transistors, promising continued minitaturization and increased computing power.
Behavioral and social factors contribute to nine out of ten leading causes of death in the US. A recent report by the Center for Advancing Health found that NIH spent only 9% of its research training funds on behavioral and social sciences, highlighting a need for increased funding and opportunities.
The Medical Event Reporting System for Transfusion Medicine aims to stop blood-transfusion errors before they happen. Researchers will analyze near misses to identify lessons that can prevent the next headline.
UT Southwestern Medical Center investigators have developed a rare case of familial filicide in which twin sisters tried to kill their own children. A new classification system, identifying 16 subtypes of filicide, aims to aid understanding and strategies for prevention.
Marshall engineers reported a peak of 1,700 Leonids meteors per hour, confirming the accuracy of computer models used to predict meteor showers. The joint operation center worked well, with representatives from NASA, U.S. Air Force and University of Western Ontario collaborating to ensure safe satellite operations.
The 1999 Fall Meeting featured press conferences on climate change, solar activity, and Mars exploration, as well as new discoveries in India and Antarctica. A digital library for Earth science education was also unveiled, providing rapid access to high-quality information.
Researchers are testing a new treatment for intracerebral hemorrhage with intraventricular extension, a rare form of stroke that affects younger people and African-Americans. The study aims to reduce mortality rates by using small doses of tissue plasminogen activator (TPA), a clot-buster commonly used in heart attacks and many strokes.
Researchers at TIGR have completed the genetic sequence of Deinococcus radiodurans, a bacteria that can withstand extreme environmental conditions. The study reveals its unique genome composition and large redundancy of repair functions, which may contribute to its exceptional radiation resistance.
The University of California, San Francisco is part of a national study evaluating medications that duplicate glucosamine and chondroitin sulfate for treating knee osteoarthritis. The four-year trial aims to assess efficacy, safety, and side effects in over 1,000 patients.
Researchers used a computer climate model to find that vegetation interactions significantly drive the Sahel region's drought. The study suggests that natural vegetation causes enhanced drying, leading to cooler climates and reduced rainfall.
