Overfishing may drive endangered seabird to rely upon lower quality food

... temperature was important, the era when the birds lived had a far greater impact on pre-breeding diet. That is, the murrelet diet in the era before the collapse of sardines and declines in other fisheries consisted of a greater proportion of more nutritious foods and fewer lower-value prey items. Post-br...

Fossil find: 'Godzilla' crocodile had head of a dinosaur, fins like a fish

...e crocodiles we know today, Dakosaurus andiniensis lived entirely in the water, and had fins instead of legs. But that's not all that made it unusual. Two other features ?its hefty size and T. rex-like snout ?have earned it a unique place in history ?and the nickname “Godzilla.?/p> Diego Pol, a postdoc...

Students discover 11,000 year old remains of Irish Elk

...ins indicates that the elk (Megaloceros giganteus) lived around 11,000 years ago. The giant deer roamed the open tundra landscape that was widespread in northern Europe at the end of the last Ice Age, as the glaciers retreated northwards. The students who found the elk were taking part in a field trip ex...

UCLA discovery will aid in treatment of patients with a deadly brain cancer

...more likely to respond to EGFR blockers. They also lived five times longer after initiating therapy than those without the variation, surviving 253 days versus 50 days. To confirm their promising work, Mischel and his team obtained tissue samples from 33 brain cancer patients treated at another facility w...

New research examines genetics of successful aging

...or women, but not both. "Historically women have lived longer than men on average, the prevalence of numerous serious diseases differs in men and women, and there are important differences in age-related physiological changes that occur between the sexes over the life span," said Dr. Zubenko. "It would ...

Sexual reproduction delays aging in a mammalian species

...-breeders, Dammann and Burda found that the former lived extraordinarily long (up to 20 years) and on average about twice as long as their non-breeding counterparts. The researchers were also able to show that this pattern was not caused by differences in intrinsic biological quality, social rank, or workl...

Duck-billed dino crests not linked to sense of smell

...rred to as the "Cows of the Cretaceous period" and lived 85 million to 65 million years ago. Evans reconstructed the dinosaurs' brain cavity using well-preserved fragments of fossilized bone and created the first-ever cast of the lambeosaur brain, which is approximately the size of a human fist. The findi...

Junk DNA may not be so junky after all

...t, the last common ancestor of human and zebrafish lived more than 300 million years ago. Because DNA sequences in each species have changed over time, traditional methods of comparing DNA sequences between humans and zebrafish have failed to identify any potential enhancers around the RET gene because the...

The world's deepest dinosaur finding - 2256 metres below the seabed

... to nine metres long and weigh up to four tons. It lived in Europe and on Greenland 210 to 195 million years ago, at the end of the Triassic Period. The Plateosaurus at the Snorre offshore field had a hollow grave. The fossil, which was found 2256 metres below the seabed, represents the world's deepest di...

First SCID gene chip to be introduced at Academy meeting on immunodeficiencies

Exciting New Breakthroughs in Diagnosis and Treatment of SCID In the past, a newborn diagnosed with SCID would not survive to his or her first birthday.

Ancient DNA provides clues to the evolution of social behavior

...eth, scientists can determine which rodent species lived in a roughly 3-mile radius of the cave at any given time. Using modern and ancient DNA from tuco-tuco teeth found in the two caves, Stanford graduate student Yvonne Chan, lead author of the PLoS Genetics study, mapped the rodent population through t...

Climate change drives widespread amphibian extinctions

...0 species of brightly colored harlequin frogs once lived near streams in the tropics of Central and South America, but about two-thirds vanished in the 1980s and 1990s. In the famed Costa Rican cloud forests, for example, the Monteverde harlequin frog disappeared in the late 1980s, as did the golden toad,...

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex

Avian flu transmission to humans may be higher than thought

The researchers report that having poultry in the household was not a risk factor for developing a flu-like illness, but having direct co...

Paleontologists learn how not to become a fossil

"They live inside the burrow of another animal, like a shrimp, or they live parasitically upon the soft tissues of another organism. These guys have a lousy fossil record," Kidwell...

Liver transplantation is not without risks, but for some patients, it is the best option and it has allowed these recipients and their families to live without fear of simple things most p...
