3-D view of Greenland Ice Sheet opens window on ice history Posted: 23 Jan 2015 11:09 AM PST Scientists using ice-penetrating radar have created 3-D maps of the age of the ice within the Greenland Ice Sheet. The new maps will aid future research to understand the impact of climate change on the ice sheet. The Greenland Ice Sheet is the second largest mass of ice on Earth, containing enough water to raise ocean levels by about 20 feet.

More light shed on on biomass breakdown Posted: 23 Jan 2015 09:17 AM PST A recently discovered family of enzymes can degrade resistant forms of starch, researchers report. Starch is a polysaccharide that is highly prevalent in both food and plants. Determining the way it is broken down by an LPMO now offers potential for utilising this starch in new ways, potentially including the production of biofuels.

Pro-marijuana 'tweets' are sky-high on Twitter Posted: 22 Jan 2015 01:59 PM PST Analyzing every marijuana-related Twitter message sent during a one-month period in early 2014, researchers have found that the 'Twitterverse' is a pot-friendly place. In that time, more than 7 million tweets referenced marijuana, with 15 times as many pro-pot tweets sent as anti-pot tweets.

Tablet computers good medium for educational materials Posted: 22 Jan 2015 12:48 PM PST It's increasingly important for educators to understand how mobile technology such as touch-screen tablets can enhance learning instead of being classroom distractions, says a professor of business administration, and co-author of new research in business and e-learning.

Surprising insights into effects of wood fuel burning Posted: 22 Jan 2015 12:48 PM PST The harvesting of wood to meet the heating and cooking demands for billions of people worldwide has less of an impact on global forest loss and carbon dioxide (CO2) emissions than previously believed, according to a new study.

Promising drug candidate protects against radiation exposure from nuclear fallout Posted: 22 Jan 2015 10:31 AM PST A drug candidate called DBIBB that increases the survival of mice suffering from radiation syndrome, even when treatment started three days after radiation exposure, has been identified by scientists. The findings suggest that DBIBB shows promise for becoming the first drug capable of treating acute radiation syndrome caused by the high levels of radiation released by nuclear explosions.
