the world. But nothing can protect them from a deadly fungus, which has helped push one of the two species of these frogs to probable extinction, and driven a decline in the second variety, new research shows.
The fungus, known as Batrachochytrium dendrobatidis, or chytrid fungus, has spread throughout the world and devastated many amphibian populations. But this is one of the first instances in which the fungus has been directly implicated in the disappearance of such a widely known species, researchers said.
They say two heads are better than one. That may or may not be true, but at the very least, two heads are more interesting.

female rays that he was caring for in an aquarium, Australian researcher Leonardo Guida saw that some of the animals had given birth, in April of this year. As he made note of the baby rays, an "oddly shaped, pale object in the water" caught his attention.

A bison in Yellowstone National Park recently awoke with a frosty blanket. What looks miserably cold to people barely registers to a bison, whose heavy…Read More »
fur is perfectly adapted to such wintery conditions.
The bison is the largest land mammal in North America. Bulls (what males are called) are more massive in appearance than cows (females), and more bearded. They can weigh more than half a ton. But don't be fooled by their size; bison are agile and quick and can run up to 30 mph (50 km/h).
Bison were nearly extinct in the 19th century due to hunting, slaughter and bovine diseases from domestic cattle. Today, Yellowstone is the only place in the lower 48 states where a population of wild bison has persisted since prehistoric times, although fewer than 50 native bison remained there in 1902. Today, the Yellowstone Park bison herd is estimated at 3,700 bison.

Typhoon Haiyan is visible even from space.
One of the most powerful storms to ever hit the Philippines, Super Typhoon Haiyan arrived on Nov. 8 with sustained winds of up 190 mph (305 km/h) in the hours before it made landfall. The aftermath of the storm can be seen in before and after false-color images captured by the ASTER sensor aboard NASA's Terra satellite.

by an extremely powerful stellar explosion, new research reports.
On April 27, several satellites — including NASA's Swift satellite and Fermi Gamma-ray Space Telescope — observed an unusually bright burst of gamma radiation. The explosion unleashed an energetic jet of particles that traveled at nearly the speed of light, researchers said.

travel too far to enjoy the spoils of nature. Shenandoah National Park straddles part of the Blue Ridge Mountains in Virginia, just 75 miles (120 kilometers) west of Washington, D.C.
The park's scenic Skyline Drive lets visitors explore the 105-mile-long (170-kilometer-long) park, with more than 75 overlooks along the way. The park's 500 miles (800 km) of trails are also a hiker's paradise, and visitors can expect to see some of the most spectacular panoramic views of the Virginia landscape from the various peaks.

A translucent underwater cave dweller that looks like a skeleton and travels like an inchworm is the newest member of California's array of marine life.

Scientists found a new species of skeleton shrimp — a group of tiny crustaceans that are actually caprellid amphipods, not shrimp — in vials collected from a small cave offshore of Southern California's Catalina Island. The two vials, one containing a male and one containing a female, were housed in the Canadian Museum of Nature in Ottawa.
