Things you do not see every day: An otter preys on a alligator at Lake Woodruff National Wildlife Refuge in Florida. The otter eventually pulled the alligator up on the bank and proceeded to consume it, as evidenced by crunching noises. They were no longer visible at that point, but the alligator was done resisting when dragged out of the water. Despite their disarmingly cute appearance, otters are the apex predator of many freshwater habitats.

A solar grill developed by Professor David Wilson at MIT allows users to cook emissions-free day or night. The grill uses a Fresnel lens and solar energy to melt down a container of Lithium Nitrate, which acts as a battery storing thermal energy for up to 25 hours. The stored heat can be used to cook at temperatures above 450ºF.
