St. Jude study solves mystery of mammalian ears

...sound waves race into the inner ear at hundreds of miles per hour, their energy—although dissipated by the cochlear fluid—generates waves in the fluid, somewhat like the tiny waves made by a pebble thrown into a pond. This energy causes the hair cell cilia in both mammals and non-mammals to swing back and ...

Massive herds of animals found to still exist in Southern Sudan

The kapok connection -- Study explains rainforest similarities

...a season, attracting bats that travel as far as 12 miles between trees and transfer pollen in the process. When the seed pods ripen, they break open to reveal fluffy fibers that are used to stuff pillows and mattresses. The seeds, which are about the size of a sunflower seed, are buoyant and able to float ...

Antarctic icebergs -- Hotspots of ocean life

...floating islands of ice – some as large as a dozen miles across – are having a major impact on the ecology ...rill and seabirds out to a radius of more than two miles around the icebergs. They may also play a surprising role in global climate change. “One importa...

Traumas like Sept. 11 make brains more reactive to fear

Healthy coral reefs hit hard by warmer temperatures

...led white syndrome in 48 reefs along more than 900 miles (1,500 kilometers) of Australia's coastline. The colorful coral colonies that attract visitors to the Great Barrier Reef live atop a limestone scaffolding built from the calcium carbonate secretions of each tiny coral, or polyp. While polyps provi...

Parasites' impact goes beyond host to affect ecosystem

...ae. The Shoals Marine Laboratory, located seven miles off the coast of Portsmouth on Appledore Island and operated jointly by UNH and Cornell University, provided the ideal setting for such an experiment. While C. lingua infects approximately 10 percent of L. littorea living on the mainland, approximate...

From the deep -- Researchers find new species of sea anemone

...d once lived on the bones of a dead whale some 1.8 miles (3,000 meters) below sea level in a region of the Pacific Ocean called Monterey Canyon, roughly 25 miles off the coast of Monterey, Calif. All of the specimens currently in Daly's collection came from this...

Cornell lab confirms deadly fish virus spreading to new species

Study shows isolation of stem cells may lead to a treatment for hearing loss

...ar to regenerate new hair cells. “Clearly we have miles to go before we reach our end goal, but the exciting part is now we can test compounds that could promote regeneration of hair cells from these precursor cells in vitro, we can study the genes expressed during the transition from stem cells to hair c...

Tracking sperm whales and jumbo squid

...ata showed that the whales were traveling up to 60 miles a day within a relatively small area, suggesting that they had found an abundant supply of food. The tagged predators and prey must have crossed paths at some time during the experiment, Gilly noted. "Based on the locations of where the squid tags...

Smithsonian scientists discover new marine species in eastern Pacific

UTSA researchers examine effects of global warming on Antarctic

...route to Antarctica, the ship passed through 1,700 miles of extensive sea ice cover that surrounds the continent annually. "We now know what the sea ice really looks like as far as its thickness and concentration and now we can compare the data collected to what we see in satellite imagery," said Xie. ...

New study sheds light on 'dark states' in DNA

...bly short length of time. Light travels at 186,000 miles per second, but in twenty picoseconds it would only travel just under a quarter of an inch. Still, a picosecond is not so fast compared to the speed of some chemical reactions in living cells. In tests of single DNA bases, the dark state lasted for...

New findings blow a decade of assumptions out of the water

...w the processes are happening within a few hundred miles of each other so the balance could be reached within a decade, the authors estimate. Deutsch compares the old assumption to a house where the thermostat is many rooms away from a window that has swung open, letting in cold air. The house could get q...
