Antarctic test of novel ice drill poised to begin

Any day now, a team of 40 scientists and support personnel expects to begin using a warm, high pressure jet of water to bore a 30 centimeter hole through 83 meters of ice. Once it breaks through to the sea below, they’ll have a few days to quickly sample life from water before the hole begins freezing up again. It's just a test. But if all goes well, in a few weeks the team will move 700 miles and bore an even deeper hole to sample for freshwater life that may have been living for eons outside even indirect contact with Earth’s atmosphere.

Warning to bats: Cuddle not

Ecologist Kate Langwig of Boston University and her colleagues want Eastern bats to listen up: No more cuddling — at least during hibernation. Just keep those wings to yourselves.

Changing seasons inspire science

Researchers are tapping into the wealth of observations being made by citizen scientists nationwide. One of the largest repositories of such data is maintained by the USA National Phenology Network.

Bat killer hits endangered grays

The news on white-nose syndrome just keeps spiraling downward. The fungal infection, which first emerged six years ago, has now been confirmed in a seventh species of North American bats — the largely cave-dwelling grays (Myotis grisecens). The latest victims were struck while hibernating this past winter in two Tennessee counties.
