Mice offer clues to the roots of human resilience
When faced with adversity, some people succumb to debilitating psychological diseases including posttraumatic stress disorder and depression, while others are able to remain remarkably optimistic. view more (2007-10-19)
In vitro models will minimize animal use in arthritis studies
It's hard to think of scientists in laboratories working toward solutions for medical problems without mice or other laboratory animals, but animals' roles in at least one major research laboratory may soon be minimal. view more (2007-10-18)
UCSB researchers discover the dawn of animal vision
By peering deep into evolutionary history, scientists at the University of California, Santa Barbara have discovered the origins of photosensitivity in animals. view more (2007-10-17)
Heaps of climate gas - Pasturing cows convert soil to a source of methane
The cow as a killer of the climate: This inglorious role of our four-legged friends, peaceful in itself, is well-enough recognised, because, with their digestion, the animals produce methane, which is expelled continuously. view more (2007-10-15)
What gives us sunburn protects crayfish against bacteria
The production of melanin gives us sunburns, but it also helps invertebrate animals to encapsulate attacking fungi and parasites. view more (2007-09-25)
National Academy of Sciences highlights UCSB study on visual attention
For our hunter-gatherer ancestors, wild animals generally represented either a food source or a potential danger. Detecting an animal's immediate presence and then monitoring its movements was vital to the physical safety, nutrition, and well-being of stone-age families. view more (2007-09-25)
Velociraptor had feathers
A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of the journal Science. view more (2007-09-21)
Penn Veterinary Medicine report new strategy to create genetically modified animals
Researchers at the University of Pennsylvania School of Veterinary Medicine have demonstrated the potential of a new strategy for genetic modification of large animals. view more (2007-09-21)
Why are some groups of animals so diverse?
A new study of finger-sized Australian lizards sheds light on one of the most striking yet largely unexplained patterns in nature: why is it that some groups of animals have evolved into hundreds, even thousands of species, while other groups include only a few? view more (2007-09-20)
260 million-year-old reptiles from Russia possessed the first modern ears
The discovery of the first anatomically modern ear in a group of 260 million-year-old fossil reptiles significantly pushes back the date of the origin of an advanced sense of hearing, and suggests the first known adaptations to living in the dark. view more (2007-09-12)
Mice use specialized neurons to detect carbon dioxide in the air
For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby. view more (2007-08-17)
Gender, coupled with diabetes, affects vascular disease development
Diabetes is associated with the development of vascular (blood vessel) disease. As we age, vascular disease becomes more common. view more (2007-08-16)
Emerging (disease) markets
Instead of attacking wild birds for our new disease problems, a far more cost effective approach should focus on keeping wild animals separate in the places where they often commingle: in wildlife markets and international trade. view more (2007-08-16)
Diet foods for children may lead to obesity
Diet foods and drinks for children may inadvertently lead to overeating and obesity, says a new report from the University of Alberta. view more (2007-08-08)
New technology reveals seal behavior
New technology has allowed an international team including UK scientists from University of St Andrews and British Antarctic Survey to witness for the first time the behaviour of the southern elephant seal (Mirounga leonina) and how it relates to its physical environment. view more (2007-08-08)
Detecting transmissibility of avian influenza virus in human households
Recent outbreaks of emerging diseases such as SARS and H5N1 avian influenza have underlined the fact that animal pathogens may acquire the ability to spread efficiently in humans - but as yet have not. view more (2007-07-26)
Did pterosaurs feed by skimming?
In order to envisage the behaviors and lifestyles of now extinct animals, palaeontology often relies on extrapolating from modern species. Scientists identify shared anatomical features and infer from these shared ways of life. view more (2007-07-24)
Scientists unravel feeding habits of flying reptiles
Scientists at the University of Sheffield, collaborating with colleagues at the Universities of Portsmouth and Reading, have taken a step back in time and provided a new insight into the lifestyle of a prehistoric flying reptile. view more (2007-07-24)
Limpets reveal possible fate of cold-blooded Antarctic animals
A limpet no bigger than a coin could reveal the possible fate of cold-blooded Antarctic marine animals according to new research published this week in The Journal of Experimental Biology. view more (2007-07-24)
Ice Age survivors in Iceland
Many scientists believe that the ice ages exterminated all life on land and in freshwater in large parts of the Northern Hemisphere, especially on ocean islands such as Iceland. view more (2007-07-20)
