Researchers at Mount Sinai School of Medicine set out to address a question that has been challenging scientists for years: How do dietary restriction -- and the reverse, overconsumption -- produce protective effects against aging and disease?
Cornell researchers have discovered a genetic mechanism in fruit flies that prevents two closely related species from reproducing, a finding that offers clues to how species evolve.
DURHAM, N.C., -- An international team of scientists has discovered a new way to classify stomach cancers, and researchers say it may be an important step toward designing more effective treatments and improving long-term survival.
Stomach (gastric) cancer is particularly prevalent in Asia and represents the second leading cause of cancer deaths worldwide.
ATLANTA - A study of how HIV mutates in response to immune system pressure by Emory Vaccine Center researchers shows that the virus can take several escape routes, not one preferred route.
The results are online and scheduled for publication in the September issue of the journal Public Library of Science Pathogens.
HANOVER, NH -- Two recent studies by Dartmouth researchers use individual genetic data to reveal the powers and limits of our current understanding of how the genome influences human health and what genes can reveal about the ancestry of the people of New Hampshire.
COLUMBIA, Mo. -- A new study from the University of Missouri may shed light on how to increase the level and quality of activity in the elderly. In the study, published in this week's edition of Public Library of Science -- ONE, MU researchers found that gene therapy with a proven "longevity" gene energized mice during exercise, and might be applicable to humans in the future.
August 10, 2009 - (BRONX, NY) - The deadliest part of the cancer process, metastasis, appears to rely on help from macrophages, potent immune system cells that usually defend vigorously against disease, researchers at Albert Einstein College of Medicine of Yeshiva University report.
Johns Hopkins researchers have developed a novel way to monitor in real time the behavior of the TB bacterium in mouse lungs noninvasively pinpointing the exact location of Mycobacterium tuberculosis. The new monitoring system is expected to speed up what is currently a slow and cumbersome process to test the safety and efficacy of various TB drug regimens and vaccines in animals.
A reduction of as little as five per cent in fisheries catch could result in as much as 30 per cent of the British Columbia coastal ecosystems being protected from overfishing, according to a new study from the UBC Fisheries Centre.
July 22, 2009 -- (BRONX, NY) -- A cellular protein that may prevent nerve cells from dying also helps to improve insulin action and lower blood glucose levels, according to a study by researchers at Albert Einstein College of Medicine of Yeshiva University (http://www.aecom.yu.edu) in collaboration with scientists at Unive
DALLAS -- July 14, 2009 -- Infectious disease specialists at UT Southwestern Medical Center have mapped the gene profiles of children with severe Staphylococcus aureus infections, providing crucial insight into how the human immune system is programmed to respond to this pathogen and opening new doors for improved therapeutic interventions.
Self-assembling and self-organizing systems are the Holy Grails of nanotechnology, but nature has been producing such systems for millions of years. A team of scientists has taken a unique look at how thousands of bacterial membrane proteins are able to assemble into clusters that direct cell movement to select chemicals in their environment.
DALLAS -- June 26, 2009 -- An enzyme that naturally occurs in the brain helps destroy the mutated protein that is the most common cause of inherited Parkinson's disease, researchers at UT Southwestern Medical Center have found.
Oncogenes are genes that when mutated or expressed in high concentrations can cause normal cells to become cancerous. Now research from Tel Aviv University is demonstrating that Ras, one of the first oncogenes discovered, has the power to heal as well as harm.
PITTSBURGH -- A group of researchers led by Carnegie Mellon University Biological Sciences Professor Aaron Mitchell has identified a novel regulatory gene network that plays an important role in the spread of common, and sometimes deadly, yeast infections.
