Gene ‘cancer-proofs’ rodent’s cells
U. ROCHESTER (US)—Despite a 30-year lifespan that gives ample time for cells to grow cancerous, a small rodent species called a naked mole rat has never been found with tumors of any kind—and now biologists think they know why. (more…)

Nanotags spot cancer early in mice
STANFORD (US)—A new biosensor chip has detected cancer tumors in mice earlier than any detection technology currently in use. The nanosensor is up to 1,000 times more sensitive and can be used to detect markers of diseases other than cancer. (more…)

Cracking the body’s circadian code
U. MICHIGAN (US)—Mathematicians say they have identified the signal the brain sends to control biological rhythms, a finding that overturns a long-held theory about our internal clock and that could point to new ways to correct sleep problems like insomnia and jet lag. (more…)

Drug may help suffocate cancer cells
EMORY—A fast growing tumor eventually outpaces its blood and oxygen supply, which drives cancer cells to send out signals that attract new blood vessels. Now, researchers have identified a chemical that stops cells for responding to low oxygen. (more…)

Same name, different lung cancer
“It is becoming increasingly clear that the genetic, cellular, and molecular nature of lung cancer in many never-smokers is different from that of smoking-related lung cancers, and there is good evidence now that the best treatment and prevention strategies for never-smokers may be different as well,” says Charles Rudin.

Heavy boozing linked to multiple cancers
“For the most part we showed that light drinkers were less affected or not affected at all,” says lead author Andrea Benedetti. “It is people who drink every day or multiple times a day who are at risk. This adds to the growing body of evidence that heavy drinking is extremely unhealthy in so many ways. Cancer very much included.”
