Three-toed sloths have a unique abdominal design -- their innards fixed to their lower ribs to avoid squashing the lungs while hanging upside down, a study said Wednesday.
The South and Central American forest dweller, also known as the brown-throated sloth, spends a large part of its life hanging from its hind legs to reach young, tender leaves growing on the tips of branches, as well as to groom.Full Story

Recently published research describes how archaeologists outfitted a customized drone with a heat-sensing camera to unearth what they believe are ceremonial pits and other features at the site of an ancient village in New Mexico.
The discovery of the structures hidden beneath layers of sediment and sagebrush is being hailed as an important step that could help archaeologists shed light on mysteries long buried by eroding desert landscapes from the American Southwest to the Middle East. The results of the research were published earlier this month in the Journal of Archaeological Science.Full Story

Few Americans question that smoking causes cancer. But they have more skepticism than confidence in global warming, the age of the Earth and evolution and have the most trouble believing a Big Bang created the universe 13.8 billion years ago, an Associated Press-GfK poll found.

Research done by U.S. scientists in the Cayman Islands suggests that native predators can be trained to gobble up invasive lionfish that colonize regional reefs and voraciously prey on juvenile marine creatures.
The invasive species with a flowing mane of venomous spines has no natural predators in the Atlantic and Caribbean Sea. Native sharks and groupers typically avoid healthy lionfish, a native to the Indian and Pacific oceans that was likely introduced through the pet trade. But when a University of Florida team tethered spry lionfish to lead weights on reefs off Little Cayman, underwater video cameras late showed nurse sharks and Nassau groupers gulping them down.Full Story
