Pygmy sloths wander inland in addition to inhabiting the mangrove fringes of their island refuge. A researchers now suggests that the population size of the pygmy sloth has been underestimated; a new, higher estimate for the number of sloths on Panama’s Escudo de Veraguas Island points to how little is known about the species, and it underscores the need to conserve the sloths’ isolated home.
Think of an object made of iron: An I-beam, a car frame, a nail. Now imagine that half of the iron in that object owes its existence to bacteria living two and a half billion years ago. That’s the upshot of a new study. Its findings have meaning for fields as diverse as mining and the search for life in space.
Pediatric diabetes researchers found that incorporating routine pet care into a child’s diabetes self-care plan can significantly improve monitoring of the disease, resulting in lower blood glucose levels.
Researchers have decoded the Australian sheep blowfly genome, adding ammunition to the battle against one of the nation’s most insidious pests. This blowfly is responsible for about $280 million in losses to Australia’s sheep industry each year from flystrike.
Individual populations of mosquitoes are under strong evolutionary pressure from humans and their environment, a new study shows.
A new study indicates a steady population trend for blue whales and an upward population trend for fin whales in Southern California.
How a chimpanzee views a video of an infant chimp from another group being killed gives a sense of how human morality and social norms might have evolved. A new study provides the first evidence that chimpanzees, like humans, are sensitive to the appropriateness of behaviors, especially those directed toward infants.
High-speed videos of lovebirds making quick in flight turns reveal how they improve sight and shorten blur by rotating their head at speeds of up to 2700 degrees per second.
Scientists have uncovered key structural differences in parrot brains that may help explain why this group of bird species can mimic speech and songs so well. These brain structures went unrecognized in studies published in the past 34 years. The results may lend insight into the neural mechanisms of human speech.
A tiny tooth plate of the 410 million year old fossil fish Romundina stellina indicates that teeth evolved earlier in the tree of life than recently thought. Jaws and teeth have been important innovations in the evolution of vertebrate animals. More than 98% of vertebrate animals have jaws.
