Two volcanoes erupting in Alaska: Scientists are monitoring and providing alerts on Pavlof and Cleveland volcanoes Posted: 24 May 2013 03:02 PM PDT Two of Alaska's most active volcanoes -- Pavlof and Cleveland -- are currently erupting. At the time of this post, their activity continues at low levels, but energetic explosions could occur without warning. Located close to the western end of the Alaska Peninsula, Pavlof is one of the most active volcanoes in the Aleutian arc, having erupted more than 40 times since the late 1700's.

Active or 'extremely active' Atlantic hurricane season predicted for 2013 Posted: 24 May 2013 11:49 AM PDT In its 2013 Atlantic hurricane season outlook issued today, NOAA's Climate Prediction Center is forecasting an active or extremely active season this year.

Monkey teeth help reveal Neanderthal weaning Posted: 24 May 2013 07:48 AM PDT Most modern human mothers wean their babies much earlier than our closest primate relatives. But what about our extinct relatives, the Neanderthals? A team of U.S. and Australian researchers reports that they can now use fossil teeth to calculate when a Neanderthal baby was weaned. The new technique is based in part on knowledge gained from studies of teeth from human infants and from monkeys.

Researchers design photobioreactor to produce biofuel from algae Posted: 24 May 2013 07:41 AM PDT Researchers have patented a new device that allows more efficiently to cultivate microalgae and can be used as raw material for biofuel or for other valuable substances in the agri-food or pharmaceutical industry.

Why early human ancestors took to two feet Posted: 24 May 2013 07:40 AM PDT A new study by archaeologists challenges evolutionary theories behind the development of our earliest ancestors from tree dwelling quadrupeds to upright bipeds capable of walking and scrambling.
