First ever worldwide census analysis of caribou/reindeer numbers reveals dramatic decline
Caribou and reindeer numbers worldwide have plunged almost 60% in the last three decades. view more (2009-06-12)
Manatees can probably hear which directions boats approach from
The world is a perilous place for the endangered manatee. While the mammals are at risk from natural threats, human activity also poses a great danger to manatee numbers. view more (2009-06-12)
Horse whisperers, lion tamers not needed: Scientists find genetic regions that soothe savage beasts
In what could be a breakthrough in animal breeding, a team of scientists from Germany, Russia and Sweden have discovered a set of genetic regions responsible for animal tameness. view more (2009-06-09)
Study shows animal mating choices more complex than once thought
When female tiger salamanders choose a mate, it turns out that size does matter - tail size that is - and that's not the only factor they weigh. view more (2009-06-09)
Engineered pig stem cells bridge the mouse-human gap
The discovery that adult skin cells can be 'reprogrammed' to behave like stem cells has been a major scientific boon, providing a way to tap the potential of embryonic stem cells without the associated ethical quandaries. view more (2009-06-04)
Resilin springs simplify the control of crustacean limb movements
Animals can simplify the brain control of their limb movements by moving a joint with just one muscle that operates against a spring made of the almost perfect elastic substance called resilin. view more (2009-05-29)
Veterinarians at high risk for viral, bacterial infections from animals
The recent H1N1 influenza epidemic has raised many questions about how animal viruses move to human populations. view more (2009-05-15)
'Beating' heart machine expedites research and development of new surgical tools, techniques
A new machine developed at North Carolina State University makes an animal heart pump much like a live heart after it has been removed from the animal's body, allowing researchers to expedite the development of new tools and techniques for heart surgery. view more (2009-05-12)
Swine flu: What does it do to pigs?
The effects of H1N1 swine flu have been investigated in a group of piglets. Scientists writing in BioMed Central's open access Virology Journal studied the pathology of the virus, finding that all infected animals showed flu-like symptoms between one and four days after infection and were shedding virus two days after infection. view more (2009-05-11)
Researchers find snippet of RNA that helps make individuals remarkably alike
"No two people are alike." Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are. view more (2009-05-06)
Animals on runways can cause serious problems at small airports
It's a bird. It's a plane. It's a potentially deadly combination. view more (2009-05-05)
Wildlife trade threatens public health and ecosystems
Wildlife imports into the United States are fragmented and insufficiently coordinated, failing to accurately list more than four in five species entering the country. view more (2009-05-04)
New light shed on the enigma of salt intake and hypertension
A high salt intake has been implicated in cardiovascular disease risk for 5000 years. But salt-sensitive hypertension still remains an enigma. view more (2009-05-04)
Limping rat provides sciatica insights
A newly developed animal model for the painful nerve condition known as sciatica should help researchers diagnose and treat it, according to Duke University bioengineers and surgeons. view more (2009-04-30)
The life histories of the earliest land animals
The fossil record usually shows what adult animals looked like. But the appearance and lifestyle of juvenile animals often differ dramatically from those of the adults. view more (2009-04-21)
Increasing carbon dioxide and decreasing oxygen in the oceans will make it harder for deep-sea animals to
New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. view more (2009-04-20)
Transplanted liver cells function in older animals but do not proliferate as much as in younger ones
When things go right, transplanted healthy liver cells transplanted by infusion or injection will find their way to the liver, integrate into the damaged tissue, start proliferating, and take over the liver's work of helping with digestion and removing waste products and worn-out cells from the blood. view more (2009-04-20)
Worms control lifespan at high temperatures, UCSF study finds
The common research worm, C. elegans, is able to use heat-sensing nerve cells to not only regulate its response to hotter environments, but also to control the pace of its aging as a result of that heat, according to new research at the University of California, San Francisco. view more (2009-04-17)
Alligators hint at what life may have been like for dinosaurs
During the last 540 million years, the earth's oxygen levels have fluctuated wildly. Knowing that the dinosaurs appeared around the time when oxygen levels were at their lowest at 12%, Tomasz Owerkowicz, Ruth Elsey and James Hicks wondered how these monsters coped at such low oxygen levels. view more (2009-04-17)
UIC biologists use DNA to study migration of threatened whale sharks
Whale sharks -- giants of the fish world that strike terror only among tiny creatures like the plankton and krill they eat -- are imperiled by over-fishing of the species in parts of its ocean range. view more (2009-04-08)
