In a coordinated effort to reintroduce the European bison to the grasslands of southern Romania, the World Wildlife Fund for Nature (WWF) and Rewilding Europe recently brought 20 bison to the Southern Carpathians. Ten more will be reintroduced over the summer. The species has been absent for about 200 years.

Greenland is now mostly white. Snow and ice and glaciers abound, but are shrinking as the climate warms. Turns out that some of the glaciers are found in canyons and the canyons are deeper than previously thought. Scientists at NASA and the University of California, Irvine (UCI), have found that canyons under Greenland's ocean-feeding glaciers are deeper and longer than previously thought, increasing the amount of Greenland's estimated contribution to future sea level rise. "The glaciers of Greenland are likely to retreat faster and farther inland than anticipated, and for much longer, according to this very different topography we have discovered," said Mathieu Morlighem, a UCI associate project scientist who is lead author of the new research paper. The results were published Sunday in the journal Nature Geoscience.

Air pollution has become one of the world's biggest threats to the future of our planet. Chronic air pollution shortens our lives and the lives of the ecologies around us. In parts of Asia, where air pollution is most pervasive, food crops and other plants are exhibiting signs of stress due to low air quality.

Yesterday morning, black oil sprayed nearly 20 feet into the air in Atwater Village, a neighborhood in Los Angeles, California after a "valve malfunction" caused the oil to leak. The LA Fire Department (LAFD) estimates that 10,000 gallons have spilled and while much cleanup progress has been made, it will will take a few days to clean up all contamination. Crude oil was spilled across a half-mile area, according to an LAFD alert. The oil spill had created a pool approximately 40-feet wide and was knee-high in some areas.

How long would you wait for six grapes? A chimpanzee will wait more than two minutes to eat six grapes, but a black lemur would rather eat two grapes now than wait any longer than 15 seconds for a bigger serving.

Beginning operation in 1934 after the repeal of Prohibition, Heaven Hill Distilleries located in Bardstown, Kentucky has become the largest family-owned and operated producer and marketer of distilled spirits in the nation. Bottling over 12 million cases of spirits in 2012, one could imagine the amounts of leftover materials that could either go to a landfill or be recycled. Fortunately, Heaven Hill decided to try recycling as part of their KY EXCEL membership. KY EXCEL is Kentucky's free, voluntary environmental leadership program open to individuals, communities, and organizations that wish to improve and protect Kentucky's environment in ways that extend beyond state requirements. Kim Harmon, the Environmental Compliance Manager at the distillery, says, "When we started our recycling program in 2011, we tried to find everything that could be recycled and vendors to take the materials. We recycle paper labels, bands around pallets, aerosol cans, brown paper packing, blue drums, label backing, cardboard, plastic and glass."

New research confirms the health benefits associated with outdoor play for children. New research from the University of Bristol shows that while most children spend the largest amount of their after-school time indoors either alone or with their parents, hours spent outdoors with friends has the greatest positive affect on a child's level of physical activity. The correlation works out like this: children get an extra 17 minutes of physical activity for every hour of time spent outdoors.

New evidence from University of Texas at Austin researchers posit that the great Mississippi's natural ability to chemically filter out nitrates is being overwhelmed. UT's hydrologists demonstrate the enormity of the filtering process for almost every drop of water that enters into the 311,000-mile long course ending in the Gulf of Mexico.

So why is Antarctica is not warming as much as other continents, and why are there more droughts in southern Australia? According to new Antarctic ice core research published in Nature Climate Change, rising levels of carbon dioxide in the atmosphere are intensifying the Southern Ocean winds, which are known to deliver rain to southern Australia, but instead they are pushing them further south towards Antarctica.
