The first 3D reconstruction of the skull of a 360 million-year-old near-ancestor of land vertebrates has been created by scientists from the Universities of Bristol and Cambridge.
The 3D skull, which differs from earlier 2D reconstructions, suggests such creatures, which lived their lives primarily in shallow water environments, were more like modern crocodiles than previously thought.
A new study by a team of Cassini mission scientists led by the University of Colorado Boulder have found that microscopic grains of rock detected near Saturn imply hydrothermal activity is taking place within the moon Enceladus.
The grains are the first clear indication of an icy moon having hydrothermal activity, in which seawater infiltrates and reacts with a rocky crust, emerging as a heated, mineral-laden solution. The finding adds to the tantalizing possibility that Enceladus, one of at least 60 Saturn moons or moonlets and which displays remarkable geologic activity including geysers, could contain environments suitable for living organisms.
It's March. It's freezing. And there's half a foot of snow on the ground. When is this winter going to end?
Many scientists think that climate change might be one cause of this year's "snowpocalypse" in Boston and bitter cold snaps in New York and Washington.
But physicists at NASA's Jet Propulsion Laboratory have been looking into another culprit: air pollution in China and India.
The U.S. Fish and Wildlife Service today proposed to protect 338,100 acres of critical habitat in Mississippi and Alabama for black pine snakes, whose southeastern, longleaf pine forests have been reduced to less than 5 percent of their historic extent. The snake depends on these forests, which are being lost to agriculture and pine plantations, fire suppression and urbanization. Black pine snakes were proposed for Endangered Species Act protection last fall as the result of a settlement agreement with the Center for Biological Diversity that speeds protection decisions for 757 imperiled species around the country.
If it seemed like Oregon has had a lot of unseasonably warm days this winter, well, it’s because we have. Now the focus is on a very low snowpack – and the implications that may have later this year.
The meteorological winter – which is comprised of December, January and February – recently wrapped up and depending on where you live in Oregon, it was one of the warmest – if not the warmest – winters on record.
Restoration of wetlands can reduce greenhouse gas emissions. This is shown in a report that has been written in part by researchers from the University of Gothenburg. Former wetlands that have been drained and which are currently used for forestry and agriculture give off 11.4 million tons of carbon dioxide equivalents. That can be compared with Sweden's total emissions of 57.6 million tons (when the land use sector is not included). But in Sweden's report to the Climate Convention, emissions from drained peatland are not visible since they are included with forest growth.
After 13 years of planning, the Solar Impulse SI2 took off last night from Al-Bateen Executive Airport in Abu Dhabi at 7:12 a.m. local time. This initiated the first leg of its historic attempt to be the first solar-powered airplane to fly around the world. If all goes well, the plane will return to Al-Bateen in June or July. As reported here in January, the first leg was a short 12-hour “shakedown cruise” to Muscat, Oman, piloted by Andre Borschberg. The plane landed safely in Muscat, more or less on schedule, at 12:14 p.m. Eastern time.
Of the two pilots who will take turns behind the wheel, Borschberg is the engineer and former fighter pilot who is intimately familiar with every detail of the plane’s design and construction.
A new study suggests that increases in atmospheric CO2 could intensify extreme droughts in tropical and subtropical regions -- such as Australia, the southwest and central United States, and southern Amazonia -- at much a faster rate than previously anticipated, explains University of Texas at Austin professor Rong Fu in a commentary in the March 9 edition of Proceedings of the National Academy of Sciences.
We lost an hour this morning, awaking to an already sunny sky. Some may feel robbed an hour from their day. So why, again, do we do this?
To some degree, we may have Benjamin Franklin to thank.
The big news from the 2015 Natural Products Expo West was that the American consumer is buying healthy foods at volumes never seen before. Health and wellness products are achieving three times the sales growth as conventional food products.
A survey conducted by SuperMarket News found that 80 percent of surveyed food-industry wholesalers and retailers had sales growth in health and wellness products. A third of survey respondents reported an astounding 20 percent increase in annual sales!
Gluten- and allergen-free is now top wellness trend
