Standing curb-side, about a block away from a congested intersection, Rob Greenfield is counting grapefruits—over a baker’s dozen he plucked from a nearby tree. He’s more than a hundred days into a year-long experiment in which he will forage or grow 100 percent of his food. On this particular day, Greenfield’s grapefruit harvest is only…

Since the beginning of human migration, the Iberian Peninsula—home of modern-day Spain and Portugal—has been a place where the cultures of Africa, Europe, and the Mediterranean have mingled. In a new paper in the journal Science, a group of 111 population geneticists and archaeologists charted 8,000 years of genetics in the region. They paint a…

A land of unrelenting wind and ice, Antarctica is about as far from verdant as any place can get. Yet cucumbers are growing on the continent’s coast. Next to them, bunches of leafy swiss chard, fresh herbs, and peppery arugula thrive. These greenhouse vegetables are the stars of one of several scientific projects underway at…

Villages inhabited by the Dai, Bulang, Lahu, Akha, and other ethnic minorities lie across ravines or peek out from the forest. Glancing up a hillside, I spot people perched in the uppermost branches of some tea trees. Our driver pulls over,…
