Researchers have found that bats have a special ability to detect the polarity of a magnetic field, meaning that the creatures can tell the difference between north and south. The only other animal known to have this ability is the mole rat, while birds, fish, amphibians, and all other non-mammals possess a different version of the magnetic compass.
The finding may not only explain bats' long-distance navigation and foraging abilities, but also may provide insight on when and how magnetic field detection evolved in mammals and non-mammals. So explain the researchers, Yinan Wang, Yongxin Pan, Stuart Parsons, Michael Walker, and Shuyi Zhang, who are from the Chinese Academy of Sciences in Beijing, East China Normal University in Shanghai, and the University of Auckland in New Zealand.

ATHENS - A tremor with a magnitude of 5.6 shook the Dodecanese island of Karpathos in Southeastern Greece early on Sunday but causing no injuries, officials said.
Doctors said the injuries sustained by the two were consistent from a lightning strike.
But those on the river find that hard to believe.
The sky was clear. Harding even held an umbrella over the brothers to shade them from the sun. No one heard a noise or saw a flash.
A man making a trip from Puerto Rico to South Florida to raise money for his religious education remains hospitalized Monday after he was struck down by a bolt of lightning which flew from clear blue sky on Sunday. He was selling religious materials when he was hit.

With no rain or even clouds to warn him of the danger, death came literally out of the blue Thursday to a self-employed landscaper. The killer was a powerful bolt of lightning that cracked through perfectly clear skies.
David Canales, 41, of West Miami-Dade, was on the job at a Pinecrest home when the bolt hit. It first seared a tree, then traveled and struck Canales, standing nearby.
Experts said Canales was killed by a weather phenomenon fittingly called a ''bolt from the blue'' or ''dry lightning'' because it falls from clear, blue skies. He was pronounced dead at South Miami Hospital.
