Wallowing in mud is more than just temperature control
Study shows how mosquitoes handle the heat of a hot blood meal
Mosquitoes make proteins to help them handle the stressful spike in body temperature that's prompted by their hot blood meals, a new study has found.
Scientists uncover surprising features of bear hibernation
Black bears show surprisingly large and previously unobserved decreases in their metabolism during and after hibernation according to a paper by scientists at the Institute of Arctic Biology at the University ...
Chip-in-a-pill may be approved in 2012
Cooling may benefit children after cardiac arrest
When the heart is stopped and restarted, the patient's life may be saved but the brain is often permanently damaged. Therapeutic hypothermia, a treatment in which the patient's body temperature is lowered and maintained several ...
Temperature rhythms keep body clocks in sync, researchers find
Researchers at UT Southwestern Medical Center have found that fluctuations in internal body temperature regulate the body's circadian rhythm, the 24-hour cycle that controls metabolism, sleep and other bodily functions.
Men perspire, women glow
Women have to work harder than men in order to start sweating, while men are more effective sweaters during exercise, according to new research published in the journal Experimental Physiology.
Greatest warming is in the north, but biggest impact on life is in the tropics
In recent decades documented biological changes in the far Northern Hemisphere have been attributed to global warming, changes from species extinctions to shifting geographic ranges. Such changes were expected because warming ...
Researchers crack cuckoo egg mystery
Researchers at the University of Sheffield have discovered that cuckoo eggs are internally incubated by the female bird for up to 24 hours before birth, solving for the first time the mystery as to how a cuckoo chick is able ...
Taking the temperature of a dinosaur
Tyrannosaurus rex is often portrayed as a cold-blooded killer, but whether the Cretaceous-era dinosaur actually had a slow, reptilian-like metabolism or a faster, more bird-like metabolism is still a mystery.
Bees warm up with a drink, too
When we venture out on a cool morning, nothing energises our body like a nice warm drink and new research reveals that bees also use the same idea when they're feeling cold.
Increased destruction of bird populations are predicted with rise in global temperatures
In 2003, a massive heat wave struck and killed some 30,000 people in Europe in an area where heat was not considered a major threat. Similar mass die-offs occur in wild birds and some mammals during heat waves, but unlike ...
A 'crystal ball' for predicting the effects of global climate change
In trying to predict how species will respond to climate change caused by global warming, researchers and scientists are turning to comparative physiology, a sub-discipline of physiology that studies how different organisms ...
Study finds respiratory symptoms more reliable indicator of H1N1, not fever alone
New research shows that individuals with mild H1N1 infection may go undetected using standard diagnostic criteria, according to a study in the August issue of the American Journal of Infection Control, the official public ...
