Twelve Epic Migratory Journeys Animals Take Every Spring

Spring is in the air, and the animal kingdom is on the move. Vernal migrations feature everything from fish and birds to big, shaggy mammals and tiny insects. These journeys are about as diverse as the species themselves, but Andy Davis, a University of Georgia ecologist and editor of the journal Animal Migration, says the mass wildlife movements have one important thing in common.

Scientists Extracted Liquid Blood From 42,000-Year-Old Foal Found in Siberian Permafrost

Last August, a group of mammoth tusk hunters unearthed the nearly intact remains of a 42,000-year-old foal during an expedition to Siberia’s Batagaika crater. Preserved by the region’s permafrost, or permanently frozen ground, the young horse showed no signs of external damage, instead retaining its skin, tail and hooves, as well as the hair on its legs, head and other body parts.

CRISPR is now being used on humans in the U.S.

The first U.S. trial of CRISPR in humans has begun, NPR reported Tuesday. Two patients are currently being treated as part of a University of Pennsylvania study. Per NPR, both have difficult-to-treat forms of cancer and both have relapsed after regular treatments. As part of the trial, researchers are taking immune cells from the patients’ own bodies and editing them with CRISPR before putting them back in. The hope is that these edited cells will be better at identifying and attacking the cancer than their unaltered counterparts. According to the U.S. government clinical trial registry, the researchers are hoping to enroll 18 people in their study. But it’s not certain yet whether they’ll be approved for that many subjects, reports Jon Fingas for Engadget. Continue reading CRISPR is now being used on humans in the U.S.
