NASA catches a shrimp below Antarctic ice

In a surprising discovery about where higher life can thrive, scientists for the first time found a shrimp-like creature and a jellyfish frolicking beneath a massive Antarctic ice sheet.

Six hundred feet (183 metres) below the ice where no light shines, scientists had figured nothing much more than a few microbes could exist.

That is why a team from the National Aeronautics and Space Administration was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera's cable. Scientists also pulled up a tentacle they believe came from a foot-long jellyfish.

"We were operating on the presumption that nothing's there," said NASA ice scientist Robert Bindschadler, who will be presenting the initial findings and a video at an American Geophysical Union meeting Wednesday. "It was a shrimp you'd enjoy having on your plate."

"We were just gaga over it," he said of the 3-inch-long (76-millimeter, orange critter starring in their two-minute video. Technically, it's not a shrimp. It's a Lyssianasid amphipod, which is distantly related to shrimp.


Mind-reading gorillas love a good game

Cajoling bored friends to keep playing with you is not limited to humans. A gorilla that wants to continue a game will also try to do this, and will even deliberately lose if necessary. This hints that gorillas may have "theory of mind" - the capacity to attribute mental states to others.


The mysterious case of the frogs' legs

In 1995, a group of schoolchildren from Minnesota discovered that half of the frogs they found in a pond were deformed. Some had bent, truncated legs, some had extra legs, while others had none at all. Photos of the frogs caught the attention of journalists, who blamed chemical pollution.

Since then, American artist Brandon Ballengée has found similarly deformed frogs and toads all over the world when working with the biologist Stanley Sessions from Hartwick College in Oneonta, New York state. Ballengée documents their field trips photographically. He also brings back dead specimens, which he uses to create artistic images like this one of an extra-limbed Pacific treefrog from Aptos, California.

Ballengée says he's attracted to the frogs because he finds them uncanny, almost other-worldly. To heighten this effect, he stains the frogs with dyes that turn cartilage blue, bones red and flesh translucent. He then scans them using a high-resolution scanner to produce a detailed, ghostly image. "I wanted to find a way to exhibit what I was finding without being scary or exploitative."

Support for Bluefin Tuna Ban Not Forthcoming

Everybody in the business knows that the Atlantic population of bluefin tuna is in worse trouble than the Pacific population, but how much worse? Well, here's one measure: Stanford University's Tag-a-Giant program is now paying $1,000 per tag to fishermen in the Atlantic and Mediterranean who return the tags after they have caught the tuna, whereas fishermen in the Pacific get only $500 for a tag. Trust the market to tell you the truth.

Another measure of the bluefin's scarcity is that two months ago, the owners of two sushi restaurants in Japan and one in Hong Kong banded together to pay $175,000 for a 513-pound bluefin tuna at Tokyo's Tsukiji fish market. The primary market for bluefin tuna is sushi, and the demand is so great that the fish are disappearing fast in both oceans.

That's why the first order of business at the CITES conference that opens in Doha, Qatar, on Saturday is a ban on the international trade in bluefin tuna. CITES, the Convention on International Trade in Endangered Species, is the only port of call, because no other international organization can intervene in defense of a fish species. Whales have the International Whaling Commission, but for tuna, CITES is all there is.

Unusually heavy precipitation and melting snows have caused the floods: Death toll in Kazakh floods rises to 33

© Alexander KhvostenkoUnusually heavy precipitation and melting snows have caused the floods.
Rescuers have discovered thirty-three bodies in southern Kazakhstan, where heavy rains swept away two dams last week, causing massive flooding, the local emergencies ministry said on Sunday.

Unusually heavy precipitation and melting snows have caused a dam to give way in the village of Zhylbulak, with a population of 820 people. The vast majority of the residents were evacuated. Another dam break has occurred in the village of Kyzyl-Agash.

"On Saturday, bodies of 33 people, including 10 men, 16 women and seven children, were discovered," the ministry said in a statement.

The statement said 44 people, including 16 children, were admitted to hospital following the flood.

Post-snow, US Northeast mops up from wind-driven rain: Six people died in storm-related accidents, and hundreds of thousands were without electricity

© AP Photo/Chris CorradinoA tree lies across a smashed car at a home in Wantagh, N.Y., Sunday, March 14, 2010. Strong winds and heavy rain downed trees and power lines throughout New Jersey, Pennsylvania, New York and Connecticut on Saturday, leaving hundreds of thousands of people without power.
Last month, the Northeast was smothered by blizzards. Now, it's waterlogged by torrential rains.

The region mopped up Sunday following a bout with high wind and heavy rains that uprooted trees, downed power lines and flooded creeks and rivers. Six people died in storm-related accidents, and hundreds of thousands were without electricity.

More than a half-million customers in Pennsylvania, New Jersey, New York and Connecticut lost electricity at the peak of Saturday's storm, which carried wind gusts of up to 70 mph. The storm came about two weeks after heavy snow and hurricane-force winds left more than a million customers in the Northeast in the dark.

Peruvian Nazca Civilization Was Destroyed by Deforestation

The collapse of the ancient Nazca civilization, long attributed to the El Nino weather phenomenon, may have actually been caused by deforestation, according to research conducted by scientists from Cambridge University and the French Institute of Andean Studies, and published in the journal Latin American Antiquity.

"The landscape only became exposed to the catastrophic effects of that El Nino flood once people had inadvertently crossed an ecological threshold," researcher David Beresford-Jones said.

The Nazca, who inhabited coastal desert areas in what is today Peru, are best known for constructing massive patterns in the desert sand that can only be seen from the air. Their civilization entered an abrupt decline roughly 1,500 years ago.

Researchers have now discovered that much of the Nazca environment was originally covered by a leguminous hardwood tree known as the huarango.


At least 2 snowmobilers dead in Canadian avalanche

Revelstoke, British Columbia - An avalanche struck an informal snowmobile rally in Canada's Rocky Mountains, killing at least two people and leaving an unknown number missing at an annual gathering best known for its party atmosphere and stunt riding.

Rescuers sent helicopters over remote Boulder Mountain at daybreak Sunday to determine if conditions were safe for a full-scale ground search after operations were halted overnight when darkness fell.

Police also conducted a door-to-door search of hotel rooms Sunday to piece together how many people were missing from the Big Iron Shoot Out rally that drew about 200 people to the mountain.

Royal Canadian Mounted Police Cpl. Dan Moskaluk said the canvass of hotel rooms left police more optimistic that the death toll would not rise significantly. He said that was because many of the snowmobilers were equipped with avalanche recovery equipment and rescued themselves.

Moskaluk said some people could still be buried on the mountain, but he could not confirm yet if anybody has been reported missing.

"Certainly we're in a better position today than we were yesterday," Moskaluk said in a telephone interview with The Associated Press. "This site will not be stood down until they are very confident, 100 percent confident that there's nobody remaining buried."
