Chronic stress is hazardous to health and can lead to early death from heart disease, cancer and of other health problems. But it turns out it doesn't matter whether the stress comes from major events in life or from minor problems. Both can be deadly.
And it may be that it's not the stress from major life events like divorce, illness and job loss trickled down to everyday life that gets you; it's how you react to the smaller, everyday stress.
The most stressed-out people have the highest risk of premature death, according to one study that followed 1,293 men for years.

Imagine a job where about half of all the work is being done by people who are in training. That's, in fact, what happens in the world of biological and medical research.
In the United States, more than 40,000 temporary employees known as postdoctoral research fellows are doing science at a bargain price. And most postdocs are being trained for jobs that don't actually exist.

For those who find themselves sleeping through work â you may one day find yourself working through sleep.
People who are fast asleep can correctly respond to simple verbal instructions, according to a study by researchers in France. They think this may help explain why you might wake if someone calls your name or why your alarm clock is more likely to rouse you than any other noise.

More women are choosing to have bilateral mastectomies when they are diagnosed with early-stage breast cancer, even though there's little evidence that removing both breasts improves their survival compared with more conservative treatments.
The biggest study yet on the question has found no survival benefit with bilateral mastectomy compared with breast-conserving surgery with radiation.

Ebola has a nasty reputation for the way it damages the body. It's rightfully earned.
"At the end stage of the disease, you have small leaks in blood vessels," says Thomas Geisbert, an immunologist at the University of Texas Medical Branch at Galveston. "You end up with essentially no blood pressure. Your body temperature drops and you go into shock."

Tobacco control advocates disagree on whether e-cigarettes are a useful tool to get smokers off tobacco, or just a sleeker form of one of the world's deadliest addictions.
A lot of that discord comes from the fact that there's just not enough science to know the risks and benefits of e-cigarettes, which deliver nicotine in a vapor rather than through tobacco smoke. And it could take years to find out if vaping causes cancer and other deadly diseases.

It's almost 4 p.m., and police officers Ernest Stevens and Ned Bandoske have been driving around town in their unmarked black SUV since early this morning. The officers are part of San Antonio's mental health squad â a six-person unit that answers the frequent emergency calls where mental illness may be an issue.
The officers spot a call for help on their laptop from a group home across town.
"A male individual put a blanket on fire this morning," Stevens reads from the blotter. "He's arguing ... and is a danger to himself and others. He's off his medications."
Scientists have taken the first steps to developing a vaccine for chikungunya â an emerging mosquito-borne virus that has infected more than a half million people in the Western Hemisphere this year. About 600 Americans have brought the virus to 43 states.
