St. Jude study solves mystery of mammalian ears

...ell cilia in both mammals and non-mammals to swing back and forth quickly in a steady rhythm. In mammals, the rod-shaped body of the outer hair cell contracts and then vibrates in response to the sound waves, amplifying the sound. In a previous study, Zuo and his colleagues showed that a protein called ...

New bacterium discovered -- related to cause of trench fever

... tens of thousands of soldiers with severe leg and back pain and recurrent fevers. The new species, recently named Bartonella rochalimae, is also closely related to the bacterium identified about 10 years ago as the cause of cat scratch disease: Bartonella henselae, which infects more than 25,000 peo...

Ancient DNA traces the woolly mammoth's disappearance

The DNA further suggests that no later than forty thousand years ago, one of the groups died out, leaving only the second alive at the time of the mammoth’s last gasp. “At a time when we should be very concerned about the...

These standard approaches to finding genes, Smith says, are relatively easy to perform in euchromatin but harder in heterochr...

Warning from Asian bees

Ice Age extinction claimed highly carnivorous Alaskan wolves

Carbon and nitrogen isotope values of the Alaskan wolf bones are intermediate between those of potential prey species—mammoth, bison, musk ox and caribou—suggesting that their diet was a mix of these large species.
