Can where you eat determine your calorie consumption? Would a fast-food restaurant, such as McDonald's or Burger King, lead to over-consumption compared to a "fast-casual" site, like Chipotle or Panera? New research suggests the opposite.

A team at MIT and Harvard has developed a new method for testing if a person is infected with Zika virus that is more sensitive, faster, cheaper, specific, easy to read, and can even distinguish between different strains of Zika virus. This new device may be a lynchpin in the battle against Zika and future outbreaks.

In this organic-crazed world, preservatives are essentially equated with deadly cyanide in terms of human harm. But, when you examine things a little more closely, the scare doesn't match reality. And it shouldn't. Most preservatives occur naturally in your diet, or in your body.

Prince's death has served to further highlight this country's enormous narcotic addiction problem. But, there's another message — the singer fell victim to very flawed pain control drugs. It's been more than 100 years since heroin and aspirin were invented, and there has been little progress in pain control since then.

Epigenetics is everywhere. Nary a day goes by without someone telling us something it explains. Epigenetics pops up frequently among non-scientists in all manner of discussions about heredity.
