These toothy deer haven't been seen in 60 years, until this October--just in time for Halloween! Kashmir musk deer may be reminiscent of Dracula but they use their fangs to challenge other males and woo females, not to suck anyone's blood. Habitat loss and poaching for their musk glands have dramatically shrunk their populations. There were five recent reported sightings of the elusive Kashmir musk deer, but no photographs were taken. The deer pictured above is its cousin, the Siberian musk deer.

You might want to limit your Halloween binge following a new recommendation from the World Hearth Organization, which states that free sugars should only make up five percent of one's daily calories. An active 10-year-old should only consume about 5.8 teaspsoons of sugar per day--that's approximately eight Starburst, or five mini peanut butter cups.

For the first time, scientists have successfully grown functional human gastric tissue in a lab. They were able to turn stem cells into stomach cells which formed a sort of a "mini-stomach" which could mimic major cellular activities off a full-sized human version.

A drone's-eye-view of the camp of the Dark Snow Project, an effort by climate scientists and geologists to find out how dust, soot, and algae are changing the reflectivity of Greenland's ice sheet. The dirty snow absorbs more heat from the sun, which quickens melting.
