Bat killer is still spreading
Since 2006, some 6 million to 7 million North American bats have succumbed to white-nose syndrome, a virulent fungal disease. That figure, issued in January by the U.S. Fish & Wildlife Service, at least sextupled the former estimate that biologists had been touting. But the sharp jump in the cumulative death toll isn’t the only disturbing new development. On April 2, scientists confirmed that white-nose fungus has apparently struck bats hibernating in two small Missouri caves. The first signs of clinical disease have also just emerged in Europe.

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.

Epidemic of skin lesions reported in reef fish
A British-Australian research team has just found coral trout living on the south side of the Great Barrier Reef sporting dark skin raised, scablike, brown-black growths. Although the authors believe they’ve stumbled onto an epidemic of melanoma — a type of skin cancer — other experts have their doubts. Strong ones.

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.
