First Right Whale Sedation Enables Disentanglement Effort:

For the first time ever, rescuers used a new sedation delivery system to help free an entangled North Atlantic right whale. The new system was developed at Woods Hole Oceanographic Institution in collaboration with NOAA and the Univ. of Florida and the Univ. of Wisconsin veterinary schools to make the animals more approachable by rescue boats.

Biologists Find World-record Colony Of Amoeba Clones In Texas Cow Pasture:

A Rice University study of microbes from a Houston-area cow pasture has confirmed once again that everything is bigger in Texas, even the single-celled stuff. The tests revealed the first-ever report of a large, natural colony of amoebae clones -- a relatively Texas-sized expanse measuring at least 12 meters across.

Airborne Ecologists Help Balance Delicate African Ecosystem:

The African savanna is world famous for its wildlife, especially the iconic large herbivores such as elephants, zebras, and giraffes. But managing these ecosystems and balancing the interests of the large charismatic mammals with those of other species has been a perpetual challenge for park and game mangers. Now a new study published in the Proceedings of the National Academy of Sciences reports the successful test of new remote-sensing technology to monitor the impact of management decisions on the savannah ecosystem.

Toxoplasmosis Parasite May Trigger Schizophrenia And Bipolar Disorders:

Scientists have discovered how the toxoplasmosis parasite may trigger the development of schizophrenia and other bipolar disorders.

First Evidence Of Planned Animal Action? Chimp's Stone Throwing At Zoo Visitors Was 'Premeditated':

Researchers have found what they say is some of the first unambiguous evidence that an animal other than humans can make spontaneous plans for future events. The report in the March 9th issue of Current Biology highlights a decade of observations in a zoo of a male chimpanzee calmly collecting stones and fashioning concrete discs that he would later use to hurl at zoo visitors.
