Food is a primal, everyday part of our lives—yet rich with mystery

What's the best way to control ecological pests? Feed them to the world's greatest predator—us

New brain research is revealing why fats and sugars may be driving more and more people toward obesity

It is the dark force, we're told, behind the obesity epidemic, the death of the family farm and Tang. But humans have been “processing” food ever since we learned how to cook, preserve, ferment, freeze, dry or extract.

Nearly two million years ago our ancestors began to barbecue. And those hot meals, Richard Wrangham argues, are what made us human

Reviving native bee species could save honeybees--and our agricultural system--from collapse
