In a new polar bear study published today, scientists from the United States and Canada found that during the first decade of the 21st century, the number of polar bears in the southern Beaufort Sea experienced a sharp decline of approximately 40 percent. The scientists, led by researchers at the U.S. Geological Survey, found that survival of adult bears and cubs was especially low from 2004 to 2006, when most of the decline occurred. 

Over the last 100 years there have been a number of attempts from electric vehicle enthusiasts to push them into the mass market. Unfortunately the vast majority of these attempts have failed for a variety of reasons, often out of the control of the market itself, but today we stand in a very different place and electric vehicles will eventually go mass-market. We hereby list five reasons why electric vehicles are here to stay in the longer term: –

Technology

There have been enormous leaps in electric vehicle technology over the last 10 years which not only offer greater efficiency but also give the driving public greater confidence. This technology continues to advance at breathtaking speed not only in the area of electric vehicles themselves but also battery technology. In many ways the development of new technologies is putting gasoline vehicles in the shadows and grabbing the headlines.

Right on the heels of his historic climate agreement with China, President Barack Obama announced a pledge of $3 billion to the United Nations’ thus far underfunded Green Climate Fund. The fund was formally established in 2010 at the U.N. Climate Change conference in Cancun. The purpose of the fund was to redistribute resources between the developed world and the developing world in order to assist developing countries in their effort to adapt to and mitigate the impacts of climate change.

On Wednesday, Nov. 12, the European Space Agency's Rosetta mission successfully landed on the surface of comet 67P/Churyumov-Gerasimenko. Descending at a speed of about 2 mph (3.2 kilometers per hour) the lander, called "Philae," first touched down and its signal was received at 8:03 a.m. PST (11:03 a.m. EST). 

Partially due to anchoring harpoons not firing, and the comet's low gravity (a hundred-thousand times less than that of Earth), Philae bounced off the surface and flew up to about six-tenths of a mile (1 kilometer) both above the comet's surface as well as downrange. At 9:53 a.m. PST (12:53 p.m. EST), almost two hours after first contact, Philae again touched down. A second, more modest bounce resulted, again sending it airborne. Philae's third contact with the comet's nucleus was the charm. At 10 a.m. PST (1 p.m. EST), the Rosetta mission's Philae lander became the first spacecraft to soft-land on a comet.

People who frequently cook meals at home eat healthier and consume fewer calories than those who cook less, according to new Johns Hopkins Bloomberg School of Public Health research.

"When people cook most of their meals at home, they consume fewer carbohydrates, less sugar and less fat than those who cook less or not at all - even if they are not trying to lose weight," says Julia A. Wolfson, MPP, a CLF-Lerner Fellow at the Johns Hopkins Center for a Livable Future and lead author of the study.

The findings also suggest that those who frequently cooked at home - six-to-seven nights a week - also consumed fewer calories on the occasions when they ate out.
