Scientists discover new ocean current

Scientists at the Georgia Institute of Technology have discovered a new climate pattern called the North Pacific Gyre Oscillation. This new pattern explains, for the first time, changes in the water that are important in helping commercial fishermen understand fluctuations in the fish stock. They're also finding that as the temperature of the Earth is warming, large fluctuations in these factors could help climatologists predict how the oceans will respond in a warmer world. The research appears in the April 30 edition of the journal Geophysical Research Letters.

"We've been able to explain, for the first time, the changes in salinity, nutrients and chlorophyll that we see in the Northeast Pacific," said Emanuele Di Lorenzo, assistant professor in Georgia Tech's School of Earth and Atmospheric Sciences.

Cloud Lightning

US: Lightning strike damages Dallas, North Carolina home

Tim Newton would have been working construction Monday if rain hadn't given him a day off.

"I was just sitting there watching TV and next thing I knew lightning stuck the house and the whole house shook," Newton said.

Newton had been sitting in the living room around 2:45 p.m. when lightning hit. He looked in the hallway and saw the smoke detector smoldering and called for help. His 1 ½-year-old son Nathan's bedroom is right by the spot where the smoke detector caught fire.

Tropical Reforestation Aided By Bats

German scientists are engaging bats to kick-start natural reforestation in the tropics by installing artificial bat roosts in deforested areas. This novel method for tropical restoration is presented in a new study published online in the science journal Conservation Biology this week.

Detlev Kelm from the Leibniz Institute for Zoo and Wildlife Research in Berlin (IZW) and Kerstin Wiesner and Otto von Helversen from the University of Erlangen - Nuremberg report that the deployment of artificial bat roosts significantly increases seed dispersal of a wide range of tropical forest plants into their surroundings, providing a simple and cheap method to speed up natural forest regeneration.

Many bats eat fruits or nectar, and thus are key species for seed dispersal and flower pollination.
