WFU study finds that moths mimic sounds to survive




In response to the sonar that bats use to locate prey, the tiger moths make ultrasonic clicks of their own. They broadcast the clicks from a paired set of structures called "tymbals." Many species of tiger moth use the tymbals to make specific sounds that warn the bat of their bad taste. Other species make sounds that closely mimic those high-frequency sounds.


First captive panda released in wild is killed

The first panda to be released into the wild after being bred in captivity has been found dead in forests in southwest China.

Xiang Xiang was found in February on snow-covered ground in the forests of Sichuan province in China's southwest, the Xinhua News Agency said.

It is believed he suffered fatal injuries after he fell from a tree while being chased by other pandas. He had undergone three years of training on how to survive in the wild but he lasted less than a year.

"Xiang Xiang died of serious internal injuries in the left side of his chest and stomach by falling from a high place," Heng Yi, an official from the Wolong Giant Panda Research Centre in Sichuan, said in a telephone interview.

South American cold wave: Argentina rations electricity, cuts gas supplies to Chile

Argentina rationed electricity to companies and severed natural gas supplies to Chile as a cold wave prompted record demand for electricity in South America's second-largest economy.

The temperature in many parts of Argentina fell below freezing yesterday, pushing electricity demand to a record 18,300 megawatts, according to the country's energy regulator. Argentina cut shipments of gas to Chile to meet the surge in demand, forcing their neighbor to rely on residual gas in the pipeline.

Lake Okeechobee ties record low as officials struggle to keep water flowing

Florida - Lake Okeechobee water levels tied their all-time low today as dry, windy conditions caused a high evaporation rate at the drought-stricken lake.

The current drought, coupled with decisions to lower the lake last year in anticipation of hurricanes that didn't materialize, left the lake at 8.97 feet on Wednesday. That was about 4 feet below normal and equal to the record low of 8.97 feet set during the drought of 2001.


NASA: Greenland snow melting faster, higher

NASA, America's space agency, said Tuesday that Greenland had more days of melting snow and at higher altitudes last year than the average established during the previous 18 years that satellite measurements have been taken.

Areas along Greenland's western, southeastern and northeastern coast saw the largest number of melt days last year.

"The sensors detected that snowmelt occurred more than 10 days longer than the average over certain areas of Greenland in 2006," said Marco Tedesco, a scientist at the Joint Center for Earth Systems Technology, which is managed by NASA's Goddard Space Flight Center and the University of Maryland.

Here is the abstract of the recent study published in the journal Eos.
