Researchers at the University of Wisconsin-Madison have identified key genes that govern critical biological tasks, revealing how a low-calorie diet slows aging. The study provides insight into the genetic basis of aging and holds promise for developing age-retarding drugs.
A study of 500 young gay men in San Francisco found that unprotected anal sex increased by a third to a half in four years. Approximately half of these cases involved partners of unknown or different HIV status.
A new hybrid of corn with more highly available phosphorus and an enzyme that helps chickens digest the mineral has been developed. Studies have shown a 41% reduction in total phosphorus levels and an 82% decrease in water-soluble phosphorus, which can help mitigate nutrient pollution in waterways.
Researchers at MIT have developed a new probe that can detect the motion of molecules in polymers as they are being stretched. This breakthrough allows for a fundamental understanding of polymer behavior, which can improve material design and mechanical properties.
A new study published in the New England Journal of Medicine found that brisk walking can reduce the risk of fatal and non-fatal heart attacks in women by 30-40%. The study analyzed data from the Nurses' Health Study, estimating one-third of coronary events among middle-aged women result from physical inactivity.
Stanford researchers used atom interferometry to measure the force of gravity on individual atoms with unprecedented accuracy. Their findings strengthen the likelihood that previous neutron interferometry experiments were incorrect, validating the power of atom interferometry as a precise measurement tool.
Physicians at Oregon Health Sciences University's Doernbecher Children's Hospital are pioneering the use of bone morphogenic protein (BMP) to grow new bone structures. Emily Lang, a 12-year-old girl with congenital deformities, is the first child to receive BMP treatment on existing bone, showing promising results.
A key study by Dr. Peter C. Molan presents the latest research on honey's effectiveness in treating wounds caused by antibiotic-resistant strains of bacteria. The results show that honey dressings can rapidly clear bacteria from infected wounds, making it a potential treatment for necrotising fasciitis.
Purdue University researchers developed a Near-Infrared Raman Imaging Microscope called NIRIM, which can analyze composite materials in real time. The instrument uses laser light to fingerprint samples as they are viewed under a microscope, providing detailed chemical information.
A study funded by the NHLBI found that emergency revascularization with balloon angioplasty or coronary bypass surgery improves survival at 6 months for heart attack patients with cardiogenic shock. Patients under 75 years old experience a 57% improvement in survival.
The US Environmental Protection Agency has awarded $8.2 million to the University of Washington for a research center studying air pollution and its effects on human health. The Northwest Research Center will examine fine particles, particulate matter under 2.5 microns in size, and their association with daily health outcomes.
