The tusk from a mammoth that lived 16,000 years ago in the Seattle area unearthed earlier this week appears to be the largest, most intact ever found in the region.

It's thought to be from a Columbian mammoth, a subgroup of woolly mammoths, and is considered to be a pretty rare find. Construction workers stumbled on it as they were digging the foundation for an apartment complex in the city's South Lake Union neighborhood.

Twenty-five years ago, two pals went out for a seafood dinner while vacationing in the Bahamas. What could be better than some fresh grouper steaks and a night on the town without the wives?

The second major volcanic eruption in as many weeks in Indonesia has killed at least three people and forced the evacuation of tens of thousands on the island of Java, as Mount Kelud spewed ash and debris 12 miles into the sky.

Thursday night's eruption of the volcano, located 50 miles southwest of the country's second-largest city of Surabaya, could be heard up to 125 miles away, Indonesia's disaster agency says, according to The Associated Press.

Termites can build huge, elaborate mounds that rise up from the ground like insect skyscrapers; scientists have now created little robots that act like termites to build a made-to-order structure.

"Termites are the real masters of construction in the insect world," says Justin Werfel of the Wyss Institute for Biologically Inspired Engineering at Harvard University. "The largest termite mound on record was 42 feet tall."
