Several specimens of a large predatory dinosaur -- including a nearly complete, exquisitely preserved skull -- were recently recovered on the island of Madagascar and announced in this week's issue of the journal Science by a team of researchers led by paleontologist/anatomist of the New York College of Osteopathic Medicine of the New York Institute of Technology.
A gene causing familial juvenile polyposis (FJP), a disorder that causes the growth of polyps in the colon or upper gastrointestinal tract, has been identified by a University of Iowa-led international research team.
A gene that helps keep bad cholesterol at bay -- and may reduce heart disease risk by 50 percent -- has been discovered by researchers reporting in this month's Arteriosclerosis, Thombosis and Vascular Biology: Journal of the American Heart Association.
Researchers used a "gating mechanism" in the coats of simple viruses to remove the genetic material and turn the remaining protein coat into a delivery system for other organic substances, including drugs. Their loaded viruses can also be altered to target certain types of cells (like cancer cells).
National Press Club "Morning Newsmaker" News Conference with Professors Robert Knecht and Biliana Cicin-Sain, of the University of Delaware Center for the Study of Marine Policy discussing critical issues facing U.S. coastal tourism and recreation industries as the largest and fastest growing economic segments of the U.S. service industry.
Sea slugs--back-boneless, ocean-dwelling creatures that look like a large snail without a shell--produce a perfume-like chemical, called a pheromone, that makes them almost irresistible to one another and helps these normally solitary animals congregate to breed, scientists at University of Texas Medical Branch at Galveston have discovered. The chemical is one of only a handful of known water-borne pheromones.
Lead in the drinking water of pregnant rats causes long-term damage to the immune systems of their offspring, according to studies in the Cornell University Institute for Comparative and Environmental Toxicology. The finding in rats -- if it holds true for pregnant human mothers exposed to lead -- could help explain the beginnings of a lifelong susceptibility to asthma and other allergies, as well as cancers.
Prof. Janine N. Caira of Ecology & Evolutionary Biology, who has conducted award-winning research on the parasites of sharks and rays, is the most outstanding North American parasitologist for 1998.
Researchers at Boston University and Scriptgen Pharmaceuticals, Inc., have successfully synthesized two compounds that open the door to the development of an entirely new class of antibiotics for use against today's increasingly drug-resistant bacteria as well as emerging forms of bacteria. In a recent issue of the Journal of Organic Chemistry, the research team reported that they have chemically synthesized myxopyronin A and B, two natural compounds known to block replication of drug-resistant strains of bacteria. Before this breakthrough, the compounds could only be isolated from their bacterial source, a process that yielded quantities too small to be usable.
High-fashion models are thin. But the first study of the majority of professional models shows a leanness that is life-threatening. These are not the handful of celebrity super models in the news, but rather the anonymous women typically seen in print and television advertising for clothing, household items, jewelry, automobiles, children's products, food and the like.
For the first time, a specific pathway for the launch of a counterattack against HIV, with cells called macrophages stimulated by CD40L to produce proteins which bolster T lymphocytes ("T cells"), scientists from the University of California, San Diego and the Veterans Affairs Medical Center reported recently in the Proceedings of the National Academy of Sciences (April 1998).
A small-scale study suggests that hyperbaric oxygen therapy may hasten recovery from stroke and save millions or even billions of dollars annually in health care costs, a medical researcher says. The study also indicates that the new approach could give doctors a vital fourth hour to intervene after the onset of stroke. Current approaches are limited to about three hours
While coronary artery bypass surgery routinely saves lives by bypassing clogged arteries, many patients have a 20 percent decline in motor function and other evidence of brain damage following surgery, a Wake Forest University Baptist Medical Center neuropsychologist said today.
UCLA Medical Center's Heart Transplant Program announced on May 5 that it has reached a collaborative agreement to begin training its surgeons and staff to install a battery-powered artificial heart replacement device developed and manufactured by ABIOMED, Inc.
Researchers at Johns Hopkins have discovered that the human immunodeficiency virus (HIV) depends on the moving parts of a cell's surface to allow it to enter the cell.
Cornell students, using a new urban planning computer software, suggest new uses for Brooklyn's Greenpoint Terminal
NASA Administrator Daniel S. Goldin and University of Arizona Alumnus, Greg Kinnear To Speak as the UA's Commencment Ceremonies Saturday, May 16, 1998.
A Laysan albatross tracked by Wake Forest University biologists has flown more than 24,843 miles in flights across the North Pacific to find food for its chick in just 90 days - flights equivalent to circling the globe.
Researchers have created transgenic mice with the widest known spectral range of vision of any mammal by introducing a gene that produces a human photopigment into mice embryos. The researchers plan to use the new mice as a tool for studying the evolution of sight and human vision problems.
Experts in emergency medicine and ultrasound have teamed up at the University of Rochester to better one of the most vital tools in the paramedic's array of equipment: endotracheal tubes, the flexible tubes inserted in the throats of hundreds of thousands of unconscious patients each year to ensure continuous delivery of oxygen to their lungs. The new device, soon to receive a U.S. patent, takes advantage of the same ultrasound technology now used by physicians to observe babies developing in the womb.
