Researchers at Universit? de Montr?al, working with teams at Massachusetts General Hospital and Johns Hopkins University, have made a major breakthrough in understanding an essential aspect of the immune system.
Researchers at the University of Pennsylvania?s School of Medicine have found by targeting the function of a single gene that it is possible to inhibit bone decay while simultaneously stimulating bone formation.
It looks, contracts and responds almost like natural heart muscle ? even though it was grown in the lab. And it brings scientists another step closer to the goal of creating replacement parts for damaged human hearts, or eventually growing an entirely new heart from just a spoonful of loose heart cells.
Common blood pressure medications might help block the spread of pancreatic cancer, researchers at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have found.
While investigating a fungus known to cause an infection in people with AIDS, two grantees of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), unexpectedly discovered a potential strategy for treating metastatic melanoma, one of the deadliest forms of skin cancer.
Sildenafil and other “impotence drugs” that boost the production of a gassy chemical messenger to dilate blood vessels and produce an erection now also show promise in unmasking cancer cells so that the immune system can recognize and attack them, say scientists at the Johns Hopkins Kimmel Cancer Center.
Researchers at Oak Ridge National Laboratory’s High Temperature Materials Laboratory are helping diesel engine and parts manufacturers develop technologies to meet tough new emissions regulations that go into effect in 2007.
Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory.
After decades of intensive effort by both experimental and theoretical physicists worldwide, a tiny particle with no charge, a very low mass and a lifetime much shorter than a nanosecond, dubbed the “axion,” has now been detected by the University at Buffalo physicist who first suggested its existence in a little-read paper as early as 1974.
The first few months of recovery from an alcohol problem are hard enough, and they’re often made worse by serious sleep problems. Now, a new study gives further evidence that insomnia and other sleep woes may actually get in the way of recovery from alcohol problems.
