Once again, researchers have taken on that perennial question: What's better for weight loss, low fat or low carb? But this time, they've added walnuts to the mix. This isn't a nutty idea, since these nuts are rich in unsaturated fats and calories.

The mosquitoes causing all the headaches these days are not key pollinators, or any sort of indicator species. They are simply pests, and 3,400 other mosquito species could fill the ecological gap just fine. It's time for vector-borne disease factories to go.

A new law that e-cigarette trade groups and public health experts uniformly support -- making sure nicotine liquid can't easily be ingested by kids -- was signed ad made official by President Obama.

The next time you make your way to a chain restaurant for a quick fix, don't utter the words "fast food." The phrase is dying. Enter "fast casual" and "fast crafted."

The CDC has issued a new, unnecessary warning to women of childbearing age. Essentially, it tells them that if they're not using birth control, do not drink. At all. Not only does this seem unduly alarmist and hyper-precautionary, but it's also not firmly rooted in sound science.

Ketamine, a dangerous 1960s hallucinogenic, may have new life for treating major depression.
