Illness is a powerful force in evolution, pushing animals to evolve a suite of behaviors - "sickness behaviors" - to help them get over those illnesses more efficiently. For a long time, doctors thought that they were just side effects of being sick, but in recent decades researchers have increasingly come to…
We've all been nagged about staying warm in the winter by a concerned elder: "You don't want to catch cold!" But that's absurd; everyone these days knows colds are only caused by viruses, right? Well, it's complicated.
Myth: Shocking someone who has flat-lined can get their heart started again.
Considering how terrible this year's flu is, odds are good that you've already become a languid pile of festering contagions. And in case you've managed to evade the virus thus far, get thee a flu shot ASAP, obviously—but then go work out. It may just double your chances of staying plague-free.
Everyone you know is sick, or getting sick, or they've become a lifeless husk of human skin full of flu germs where there was once organs and bones and blood. Don't believe it? Check out Google's influenza tracker, which shows just how massive this year's spike is.
While scientists increasingly understand the genetics of cancer, they've never been able to track how single cancerous cells form tumors in the body, or work out how tumors grow back seemingly from nowhere. New research, however, sheds some light on that problem—and suggests that tumors are fueled by cancer stem cells.
If you've been walking around a public place lately, you've come in contact with a lot of people. Some of those people may have been sick. And if you've been hanging around enough of them as they cough and sneeze, then you might be about to get sick too.
Written and directed by Andy Abrahams Wilson, the 2008 Academy Award-nominated documentary Under Our Skin explores and exposes one of our nation's most threatening and least regarded epidemic illnesses: Lyme disease.
A young researcher from San Francisco has died after being infected by a highly virulent strain of meningococcal disease he was studying—and there are fears that it could spread.
A mysterious illness that begins as a high fever with little appetite and spreads to a rash on the hands and feet is responsible for the loss of 17 lives, so far, in an impoverished Vietnamese district. 171 others have also been sickened but have been able to recover with proper and timely medical care.
A new broad-spectrum treatment for viruses could be as effective as antibiotics fighting bacteria, MIT researchers report. The method uses cells' own defense systems to induce invaded cells to commit suicide, preventing the spread of the virus. In lab tests, the new drug completely cured mice that had been infected…
The moment you're semi-sure you're getting a cold, get some zinc lozenges. That's the result of a meta-analysis of 15 different scientific studies of the mineral, and cut the length of coughing and sneezing days by 40 percent.
It can be easy to let the contentious question of who will pay for healthcare in our society distract from questions of what it will pay for. Trends consultancy PSFK shares its vision of where technology will soon take medicine.
One of the first things we noticed when Steve Jobs came out on stage was that he was noticeably thinner than he was in previous events. We were vaguely concerned since he's had a recent history of what could be considered pretty severe health problems, but it looks like it's just a "common bug" says Apple PR. At age…
