Study finds starfish shed arms to protect against overheating
Primate hibernation more common than previously thought
(Phys.org) —Until recently, the only primate known to hibernate as a survival strategy was a creature called the western fat-tailed dwarf lemur, a tropical tree-dweller from the African island of Madagascar.
Chickens with bigger gizzards are more efficient
According to animal scientists, farmers could further protect the environment by breeding chickens with larger digestive organs. This research, published in the February issue of the Journal of Animal Science, could solve ...
Study shows extinction of pseudosuchians may have helped dinosaurs flourish
Harnessing robot research a searching task
A new laboratory dedicated to technologies at the cutting edge of an emerging field of robotics could radically improve the way search and rescue operations are conducted. The Monash Swarm Robotics Laboratory ...
Researchers crack olfactory code for partner selection, synthesise first biologically effective perfume
(Medical Xpress)—Individual body odour plays an important role in partner selection. Humans, mice, fish and birds, and probably other vertebrates too, receive important information about a potential partner's ...
For some feathered dinosaurs, bigger not necessarily better
Every kid knows that giant carnivores like Tyrannosaurus rex dominated the Cretaceous period, but they weren't the only big guys in town. Giant plant-eating theropods – close relatives of both T. rex and t ...
Cutting Bergmann's Rule down to size

Why whale sharks need to swim near the surface
(Phys.org)—Whale sharks, the world's biggest fish, can dive to chilly waters hundreds of metres deep but they need to return to the surface to warm up, according to a new study led by researchers from The ...
New study finds evolution mostly driven by brawn, not brains
The most common measure of intelligence in animals, brain size relative to body size, may not be as dependent on evolutionary selection on the brain as previously thought, according to a new analysis by scientists.
Developmental biologist proposes new theory of early animal evolution, challenges basic assumptions
A New York Medical College developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions—that survival is based on a change's ...
Skin hair skims heat off elephants
Body hair in mammals is typically thought to have evolved to keep us warm in colder prehistoric times, but a new study suggests that it may do the opposite, at least in elephants. Epidermal hair may have ...
Harvard researchers develop new kind of soft robotic gripper
Sunbathing helps these bugs stay healthy
Sunbathing may be healthy – at least for one group of North American insects that apparently uses the activity to fight off germs, Simon Fraser University scientists have found.
