The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do. But now, geochemists from Brown University have found a mineral structure with which the nobles deign to fraternize. Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...

Humans Left Africa Later Than Thought
2013-06-12 08:51:11

redOrbit Staff & Wire Reports - Your Universe Online Modern humans did not leave Africa prior to the massive eruption of Sumatra´s volcano Mount Toba 74,000 years ago, according to a new study appearing in the journal Proceedings of the National Academy of Sciences.

Mauna Kea is a dormant shield volcano that is located on the island of Hawaii and reaches an elevation of 13,803 feet. It is one of five volcanoes that comprise the island and is thought to be about one million years old. Mauna Kea, like all Hawaiian volcanoes, was created when the Pacific tectonic plate passed over a volcanic hotspot. The Hawaiian volcanoes, which extend over an area known as the Hawaiian Ridge – Emperor Seamount chain, have been well studied, but it is not known how the...
