Fishermen and scientists have found pieces of the unusual Pacific barreleye fish in their nets since 1939, but the first photos of live, intact fish were released today. Their grayish, barrel-like fish eyes are upright tubes, which are protected by a transparent dome on the top of the head, similar to the cockpit of a fighter plane.

Songbirds fly faster than scientists thought they did--two to three times faster, in fact! A researcher from York University in Toronto outfitted wood thrushes and purple martins with miniature geolocators and tracked them as they migrated. The geolocators work by detecting light, which allows scientists to estimate the latitude and longitude where the data was recorded.
Scientists found that the birds fly two to six times faster during their spring return journey than in fall. One purple martin flew from Brazil to back to its breeding colony in the United States in only 13 days!
Today is the 200th anniversary of the birth of Abraham Lincoln and Charles Darwin. Abraham Lincoln, the 16th President of the United States, led the country through the Civil War.

The oldest human hairs ever found were discovered in an unusual place--hyena poop! Researchers found the rock-hard dung in a cave in South Africa. They used tweezers to extract 40 fossilized hairs resembling glass needles from one of the hyena coprolites, or fossil turd.
Fossils of Titanoboa cerrejonesis were unearthed in a coal mine in Colombia. Studies show that this snake, which lived 60 million years ago, was the biggest snake ever at 42 feet (13 meters) long and weighed almost a ton at 2,000 pounds (1134 kilograms). "That's longer than a city bus and ... heavier than a car," said lead study author Jason Head, a fossil-snake expert at the University of Toronto Mississauga in Canada and a research associate with the Smithsonian Institution.
Uh-oh! The groundhog saw its shadow this morning, which means six more weeks of winter are on the way. Tradition says that if Punxsutawney Phil sees his shadow on February 2, winter will last another six weeks. However, if Phil does not see his shadow, there will be an early spring.
