Gray-haired men and women alike often wonder whether to dye their hair or leave it be. But a new option may soon be available, following a gene discovery that may allow for delaying, or even halting, gray hair growth. That change could potentially alter how we guess a person's age.

If you have a hidden agenda, it’s best to try and hide it. That's what we’d recommend after reading a misleading, unbalanced report on the website Quartz. The reporter's unsupported piece isn’t really about meat consumption and how it’s making men sick — it's about meat and how it’s making her sick.

Takotsubo cardiomyopathy, or “broken heart syndrome,” has always been associated with a negative emotional trigger, which can lead to sudden cardiac death. But new research reveals for the first time, that positive emotions can also precipitate this condition.

Energy drinks are popular — especially among younger consumers. Their high caffeine content can certainly give one an energy boost. But apparently that's not all they can do, and people with cardiac conditions or a family history of such would be well advised to limit their intake of these beverages.

Ever wonder if it’s really safe to eat food quickly after dropping it on the ground? Science suggests that it may be alright to do so -- however, there are conditions, because it all depends on what you drop and where you drop it. But given the proper circumstances, the so-called "5-second rule” can work to keep illness at bay.

This fiasco is a hilarious lesson about what happens when you try to take a crappy drug, and attempt to lobby it into a good one. Or at least one that the FDA would approve. This sorry saga has it all. Good guys, bad guys, idiots, and one women who walked away from it filthy rich. Enjoy.

When properly equipped for the bitterness of winter, most people don't experience unusually cold hands and feet that turn colors, especially if gloves and warm socks are involved. But for some the painful experience is actually a disease: it's called Raynaud's, and it affects roughly 28 million Americans.

Online weight-loss programs are convenient — you can access them from home whenever it suits you. But how good are they? It's hard to tell sometimes just from looking at the site. A new study suggests that consumers and their healthcare providers take a close look before advising or using many of these sites.

Katherine Schreiber, Health Editor at Cosmopolitan, wanted to get to the bottom of the issue on one diet fad that's been around for decades - giving up carbohydrates. Carbs are, of course, an essential food, but during a previous health craze, low-fat, people took in a lot more carbs.
The American Council on Science and Health has long been trusted guides for the public when it comes to separating food fads from nutrition science, so Schreiber got together with the Council's Senior Nutrition Fellow, Dr. Ruth Kava, to talk about the downside to low carbs.

Sharing is caring, right? Researchers from Belgium have discovered that, after some years, married couples' immune systems tend to look alike. This isn't surprising, given that many couples share the same lifestyle habits; from eating the same meals, exercising together, and sharing the same germs when one spouse is sick.. Gross. Kinda cute, but gross.
