When humans talk to each other or walk alongside each other, we tend to match each other's subtle movements.

Called interpersonal movement synchrony in the science literature and mirroring in the popular media, it's an often-unconscious process during which we match our gestures and pace to that of our social partner of the moment.

Civilization originated in the Fertile Crescent region, including parts of modern-day Iraq, Syria, Lebanon, Jordan, Israel and Egypt. That's the lesson most of us learned in school.

In it, civilization is used in a highly positive way to refer to the rise of city-states and the development of writing around the 4th millennium B.C.

Much of the U.S. remains firmly in the grip of winter, even as the sports-enthused world prepares to cheer on athletes in snow-and-ice-centered events at the Winter Olympics.

Late last year, an infant elephant in the state of Kerala in India fell into a well as the baby's herd moved to cross a river.

Together, villagers and government officials mounted a five-hour rescue, using heavy earth-moving equipment to clear a path of packed-down soil that allowed the youngster to climb out.

You know your cats' cute habits, their distinct personalities and their likes and dislikes for food, play and affection.

In a post published by the conservation organization Dian Fossey Gorilla Fund International (DFGFI) last month, the behavior of a mountain gorilla female in Rwanda was described in striking terms.

The 26-year-old female, named Pasika, has been traveling alone with her baby for more than seven months in Rwanda's Virunga mountains, ever since her social group fell apart at the death of its silverback leader. Her infant, Mashami, is now one year old.
