Caught by a camera trap, a leopard prowls under the dense canopy of the Jeypore-Dehing lowland rain forest in the northeast Indian state of Assam (map).

Released in February, the picture was taken during a two-year survey by the Wildlife Conservation Society (WCS). The research found seven cat species in a 354-square-mile (570-square-kilometer) range—the highest diversity of cat species yet photographed in a single area.

Partly funded by WCS, wildlife biologist Kashmira Kakati had been studying the gibbons of Jeypore-Dehing and became curious about the predator tracks she kept finding on the ground.

"I said, I need to find out what's there," Kakati told National Geographic News. "Nobody had any clue. People who had been in the forest 30 years didn't know."

With 30 digital camera traps, Kakati captured not only the cats but a number of other rare forest animals between 2007 and 2009. "Even I was surprised by the result," she said. (See related pictures of a rare Chinese wildcat snapped by a camera trap.)

See-Through Vision Invented

... at least for a very thin barrier. A glass lens and a sugar cube are shown in a picture, each next to a mathematical formula describing how light passes through it.

Scientists have figured out how "see" through opaque barriers by unscrambling what little light passes through.

Water Found in Apollo Moon Rocks

Recently NASA crashed two spacecraft into the moon and orbiters scanned the lunar surface for telltale light signatures—all to confirm the rocky body isn't bone dry after all.

But, it turns out, solid evidence for water on the moon was under our noses the whole time.

Tiny amounts of water have been found in some of the famous moon rocks brought back to Earth by the Apollo astronauts, scientists announced last Wednesday. (Related: "Apollo 11 at 40: Facts, Myths, Photos, and More.")

The water levels detected in Apollo moon rocks and volcanic glasses are in the thousands of parts per million, at most—which explains why analyses of the samples in the late 1960s and early 1970s concluded that the moon was absolutely arid.

"Only in the last decade have instruments become sensitive enough to even analyze water at those kinds of concentrations," said Gary Lofgren, the lunar curator at NASA's Johnson Space Center in Houston, Texas.

Lofgen, who wasn't involved with the new research, called it "solid work" worthy of further investigation.

Epic Iceberg Smashup Could Change Currents


Giant Iceberg Headed for Trouble

Pictured in a January 7 satellite image—about a month before a massive collision—the Luxembourg-size iceberg B9B floats toward the hundred-mile-long (160-kilometer-long) floating "tongue" of Antarctica’s Mertz Glacier. The tongue is already weakened by growing rifts on both sides of its midsection.

The 60-mile-long (97-kilometer-long) B9B iceberg smashed into the Mertz Glacier Tongue on February 12 or 13—creating a second, 48-mile-long (78-kilometer-long) iceberg, according to a the Antarctic Climate and Ecosystems Cooperative Research Centre (ACECRC).

The two icebergs are now floating at sea, side by side, and debris from the breakup is filling the once clear waterway beside Mertz Glacier (map). Prior to the separation, iceberg B9B had spent nearly 20 years floating close to the glacier.

Some experts warn the newly floating ice could seriously impact ocean circulation—causing unknown consequences for Earth's climate and the region’s marine animals.
