Climate change is pulling the sea ice out from under polar bears’ feet, forcing them to swim longer distances to find food and habitat. Long-distance swimming puts polar bears at risk of drowning due to fatigue or rough seas.
A report published by the World Watch Institute in 2009 revealed that greenhouse gases produced by livestock comprise 51 percent of global greenhouse gas emissions.
Methane gas, the gas produced most fervently by livestock, traps 100 times more heat in the atmosphere than carbon dioxide within a 5 year period, and 72 times more within a 20 year period. The good news is that methane also leaves the atmosphere within a decade, whereas carbon dioxide takes several decades or even centuries. This means that a drastic shift away from raising livestock offers a very real hope that we can curb global warming.

Inside a single wheel-shaped droplet of liquid helium rotating 2 million times per second, scientists have spotted a storm of dozens of tiny tornadoes whirling around.
The droplets of liquid helium spun 100,000 times faster than in any previous experiments. The grid of quantum tornadoes inside the droplets could reveal interesting information on the bizarre nature of “superfluid” liquid helium and the nature of quantum rotation, say the international team of scientists involved in the study.
"The quest for quantum vortices in superfluid droplets has stretched for decades," Andrey Vilesov, a professor of chemistry at the University of Southern California, said in a statement. “But this is the first time they have been seen in superfluid droplets.”
A team of researchers at Michigan State University has developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a clear surface. And, according to Richard Lunt of MSU’s College of Engineering, the key word is “transparent.”
