In 2010, the National Institutes of Health made arrangements to move some retired chimpanzees back into the research, spurring protests.

December 17, 2012 Secretions from a brown frog's skin contain chemicals that might be useful in fighting bacteria. Russian researchers are cataloging compounds in the slimy goo. Although the odds against them are long, the researchers hope their work will aid the search for new drugs.
December 14, 2012 Researchers wanted to take a census of all of the insects living in a small section of rainforest in Panama. To do this, they went up in a balloon, hung from a crane and walked atop the canopy in a huge tree raft. All told, they collected almost 130,000 specimens from more than 6,000 species.

December 10, 2012 The barbs on porcupine quills help them pierce the skin. If the bumpy needles work so well for the big rodents, couldn't they they also help doctors and nurses giving injections? Designers of medical devices are looking to try the porcupine approach.
December 4, 2012 Stray cats prowl freely among many of the city's ancient monuments. At the Torre Argentina ruins, a cat shelter has been caring for felines for two decades. But archaeological officials now say the shelter, built in the foundations of an ancient temple, must be closed.
