Nobel Prize in Medicine Awarded to Cellular-Transport Researchers

The 2013 Nobel Prize in Physiology or Medicine has been awarded to James E. Rothman, Randy W. Schekman and Thomas C. Südhof "for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells". » 10/07/13 8:40am 10/07/13 8:40am

The first evidence that lifestyle changes can reverse aging

A new five-year pilot study has shown that lifestyle changes, like an improved diet, exercise, and stress management, may help reverse aging processes at the cellular level. But as exciting as this finding is, we’re still far from the proverbial fountain of youth. » 9/17/13 8:00am 9/17/13 8:00am

Think your sex life is complicated? Imagine having 7 sexes.

No, this isn't something out of an Octavia Butler novel. It’s Tetrahymena thermophila — a single-celled organism that goes way beyond male and female. It has seven different sexes to choose from. Now a new study published in PLOS has finally made sense of its bizarrely complex and seemingly random sex life. » 3/27/13 2:30pm 3/27/13 2:30pm

These live stem cells were recovered from a 17-day-dead human corpse

Researchers at the Pasteur Institute in Paris have discovered that certain stem cells can stay alive in human corpses for at least 17 days after that person is declared dead. What were we saying the other day about the difficulty with defining death? » 6/12/12 5:00pm 6/12/12 5:00pm

Fetuses can donate their stem cells to help heal their mothers' hearts

Researchers have known for some time that women who experience weakened heart function in the months before and after childbirth (a condition known as peripartum cardiomyopathy) recover more quickly than any other group of heart failure patients. Now, a team of researchers from Mt. Sinai School of Medicine thinks it… » 11/22/11 2:20pm 11/22/11 2:20pm

The Shark Immunity Factor that Could Save Your Life

Scientists have known for some time that dogfish sharks, like the one pictured up top, naturally produce a broad-spectrum antibiotic called squalamine in their livers. Now, new research into the cellular function of squalamine reveals how it also confers a broad-spectrum antiviral benefit for the shark — one we humans… » 9/20/11 12:58pm 9/20/11 12:58pm
