When cells become cancerous, they also become 100 times more likely to genetically mutate than regular cells, researchers have found. The findings may explain why cells in a tumor have so many genetic mutations, but could also be bad news for cancer treatments that target a particular gene controlling cancer malignancy.
Stanford history Professor Robert Proctor will speak about the tobacco industry February 18 during a symposium — ”The Sociopolitical Manufacturing of Scientific Ignorance” — at the annual meeting of the American Association for the Advancement of Science in San Francisco.
A 46-year-old former fitness instructor, suffering from biventricular end-stage heart failure and in irreversible cardiogenic shock, has become the first to receive a new temporary Total Artificial Heart in the Northeast U.S. by cardiac surgeons at the University of Pennsylvania Health System.
In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation happens, yet not what regulates it.
Preliminary findings from the largest genome scan ever completed in the history of autism research are being published today in Nature Genetics. University of Pittsburgh researchers with a consortium of scientists from across the world contributed to this landmark research endeavor through the Autism Genome Project.
Health Canada, the Canadian government regulatory agency, has approved wide-ranging new health claims for COLD-fX, the most popular cold/flu remedy in Canada.
Tomorrow AAAS Fellow, Robert C. von Borstel will talk about how cancer cell mutation and selection are metaphorically similar to the evolution of a new species.Like the first pregnant finch that landed in the Galapagos, the first cancer cell in a body has to undergo many mutations through many generations to establish itself. But once there, like any newly stabilized species in different ecological niches, cancer is tough to get rid of.
New data, presented at the American Association for the Advancement of Sciences (AAAS), suggests cocoa flavanols may enhance brain blood flow and improve cognitive health.
Researchers from the University of Southern California received approximately $3.4 million from the California Institute for Regenerative Medicine for stem cell research.
Bioengineers and public health researchers at Harvard University have developed a novel spraying method for delivering the most common tuberculosis (TB) vaccine, providing a new low-cost and scaleable technique that offers needle-free delivery and greater stability at room temperature than existing methods.
