Researchers have discovered a gene that can protect elephants from cancer. An estimated 17 percent of humans worldwide die from cancer, but less than five percent of captive elephants—who live for about 70 years, and have about 100 times as many potentially cancerous cells as humans—die from the disease. “This
Researchers have developed a technique that offers new insight into “cellular memory.” The cells in our body divide constantly throughout life. But how do cells remember whether to develop into a skin, liver, or intestinal cell? It’s a question that has puzzled scientists for many years. With the new research,
Rudolph’s glowing red nose may not be entirely the stuff of kids’ Christmas stories after all. Although reindeer noses aren’t typically red, or infused with enough light to guide a sleigh, Steve Farber, a professor of biology at Johns Hopkins University and principal investigator at the Carnegie Institution for Science,
A new technology that will dramatically enhance investigations of epigenomes, the machinery that turns on and off genes and a very prominent field of study in diseases such as stem cell differentiation, inflammation and cancer, is reported on today in the research journal Nature Methods. The examination of epigenomes requires
U of T researchers have discovered how severely damaged DNA is transported within a cell and how it is repaired. It’s a discovery that could unlock secrets into how cancer operates — a disease that two in five Canadians will develop in their lifetime. “Scientists knew that severely injured DNA
The recently revealed genome of Strigamia maritima, one of those scary centipedes we found in our houses (more or less startled) shows how the evolution responds with alternative responses to threats and troubles. Centipedes are members of the arthropods, a group with numerous species including insects, spiders and other animals.
