Most animals leave their home turf when they reach adulthood to avoid competing with relatives. But here's an exception: More than three decades of dogged research shows that prairie dogs are more likely to disperse when all of their family members are gone.

For more than a century, neurons have been the superstars of the brain. Now researchers say that when they placed human versions of another type of brain cell into mice brains, the mice grew up to be faster learners. This supports the hypothesis that these glial cells — and not just better-known neurons — play an important role in learning.

Bees and flowers communicate in colors, scents and shapes. Now scientists have discovered that bumblebees can also sense flowers' electric fields. This sixth sense helps them remember and recognize nectar-rich blooms while foraging.

In New Jersey, thousands of discarded Christmas trees have dodged the wood chipper and hit the beach instead. They're being used to jump-start new dunes, but scientists warn that these man-made dunes could be less sturdy than dunes that form naturally.

What killed the dinosaurs? It's history's ultimate murder mystery, and for decades the prime suspect has been a giant asteroid. New data suggest that it struck right before the extinction. But scientists say it still may not tell the full story of what happened to the dinosaurs.

In the early days of the NFL, the average lineman weighed 190 pounds. Now they average 300 pounds. A look at the physics behind a tackle shows that bigger and faster players means harder slams to the turf and more severe injuries.

The world is full of data — and that's a problem. We have to find a place to store all those digital photos, tax records and unfinished novels. British scientists have demonstrated a possible solution: They've stored all of Shakespeare's sonnets on several small stretches of DNA.

Gin, Jesuit priests, communist bravado — the history of malaria is littered with strange bedfellows, as our video shows. The parasite has proved to be a wily foe, frustrating human efforts to control it time and time again.

Scientists have detected milk fat on 7,000-year-old pottery vessels from archaeological sites in Northern Europe. They think it's the earliest evidence of cheese-making, and they argue dairy products gave early farmers an evolutionary edge.
