Fighting air pollution with innovation and technology
May 19, 2014 10:46 AM - ENN Editor
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.
10,000-Gallons of Crude Oil Spilled in L.A.

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.

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.
Overwhelming the Mississippi
May 14, 2014 10:52 AM - Robin Blackstone, ENN
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.
Carbon Dioxide pushing weather around in the southern hemisphere

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.
A greener barbecue

Memorial Day, the unofficial start of summer and outdoor cooking season is right around the corner. Unfortunately, outdoor cooking is too often connected with a tremendous amount of waste. Make this year's summer the "summer of green" with these eco-friendly alternatives for a low-impact summer barbecue:
Says the human to the polar bear: "I am not your lunch!"
May 9, 2014 09:03 AM - Robin Blackstone, ENN
As the climate continues to change, the polar bear's range moves south as the planet continues to warm. This means that we should expect more human encounters with the polar bear. This can be a problem for scientists working in these regions. Enter the Canadian bear expert, Andy McMullen, a Canadian 35 year veteran who teaches Dartmouth scientists about bear behavior before they embark upon studies in bear country.
Polar bear genome reveals adaptations to high-fat diet
May 9, 2014 08:02 AM - Allison Winter, ENN
Living its life in the high Arctic, polar bears have developed extreme adaptations to survive in this cold sea ice environment. One important trait is their thick layer of blubber. Like other arctic animals, this layer of fat helps insulate species from the cold. Consequently, polar bears have adapted to subsist on a blubber-rich, high-fat diet of marine species. But is a high-fat diet healthy for the species?
Predicting red tide blooms with ESP
May 8, 2014 10:54 AM - Robin Blackstone, ENN
Red tide poisoning is an aquatic phenomenon caused by a rapid increase/accumulation in the water column of reddish colored algal bloom (large concentrations of aquatic microorganisms) comprising a few species of toxic dinoflagellates. Forecasting the phenomenon has been critical for coastal communities. This year though, WHOI is introducing a new tool called Environmental Sample Processors (ESP) to measure bloom concentration and associative toxins for real-time reporting to land based researchers.
