Scientists have pinpointed the ticklish bit of a rat's brain.

The results, published in the journal Science, are another step toward understanding the origins of ticklishness, and its purpose in social animals.

A report out this morning from Australian investigators offers a handful of new clues about the greatest aviation mystery of the 21st century: the disappearance of Malaysia Airlines Flight 370.

The remains of two gigantic dinosaurs discovered in Australia may shed light on how dinosaurs spread across the globe.

The news this week.

For that reason, we're bringing you this photo of a baby elephant named Jotto cuddled up to an ostrich named Pea.

Conservationists with the David Sheldrick Wildlife Trust in Kenya came across Pea two years ago today, while they were rescuing a different infant elephant. The trust is well-known for its rescue and rehabilitation program for orphaned elephants.
