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."

Imagine five people out walking together along a river. Three are adults, the other two of juvenile age. As they walk together, they leave footprints in the mudflats.

Eight-hundred-thousand years later, a team of 12 archaeologists led by Nick Ashton of the British Museum and University College London announced its discovery of those footprints.

Originally published on Thu February 13, 2014 8:01 pm

Until recently, finding characteristic stone and bone tools was the only way to trace the fate of the Clovis people, whose culture appeared in North America about 13,000 years ago.
Sarah L. Anzick Nature

The mysterious Clovis culture, which appeared in North America about 13,000 years ago, appears to be the forerunner of Native Americans throughout the Americas, according to a study in Nature. Scientists have read the genetic sequence of a baby from a Clovis burial site in Montana to help fill out the story of the earliest Americans.
