SALT LAKE CITY, May 28, 2010 – A new species of horned dinosaur unearthed in Mexico has larger horns that any other species – up to 4 feet long – and has given scientists fresh insights into the ancient history of western North America, according to a research team led by paleontologists from the Utah Museum of Natural History at the University of Utah.

DALLAS – June 1, 2010 – New research from UT Southwestern Medical Center suggests that allergic reactions to pet dander, dust mites and mold may prevent people with allergic asthma from generating a healthy immune response to respiratory viruses such as influenza.

Men with a deep, masculine voice are seen as more dominant by other men but a man's own dominance – perceived or actual – does not affect how attentive he is to his rivals' voices. His own dominance does however influence how he rates his competitors' dominance: the more dominant he thinks he is, the less dominant he rates his rival's voice. These findings[1] by Sarah Wolff and David Puts, from the Department of Anthropology at Pennsylvania State University in the US, are published online in Springer's journal Behavioral Ecology and Sociobiology.

Three new UCSF studies describe the wide reach of the tobacco industry and its influence on young people, military veterans and national health care reform.

The analyses will be published in a special July edition of the American Journal of Public Health titled "Modeling to Advance Tobacco Control Policy."

Scientists using tiny particles of genetic material to interfere in the replication process of the deadly Ebola virus have successfully prevented monkeys exposed to that virus from dying of hemorrhagic fever. The proof-of-concept study, published in this week's issue of The Lancet, suggests that such protection also should be possible in humans.

Scientist Jon Chase once worked in a lab that set up small pond ecosystems for experiments on species interactions and food webs.

"We would try to duplicate pond communities with a given experimental treatment," he says.

"We put 10 of this species in each pond, and five of these species, and eight of the other species, and 15 milliliters of this nutrient and 5 grams of that and 'sproing,' every replicate would do its own thing and nothing would be like anything else.

Individuals who have poor oral hygiene have an increased risk of heart disease compared to those who brush their teeth twice a day, finds research published today on BMJ.com.

ANN ARBOR, Mich.---Every autumn, as predictably as falling leaves, flu season descends upon us. Every spring, just as predictably, the season comes to a close. This cyclical pattern, common in temperate regions, is well known, but the driving forces behind it have been in question.

For kidney patients trying to control their blood pressure, reducing fluid build-up in the blood is more effective than using antihypertensive medications, according to an analysis appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The research suggests that lowering salt intake may help reduce build-up.

Jeffrey Long's lab will soon host a round-the-clock, robotically choreographed hunt for carbon-hungry materials.

The Lawrence Berkeley National Laboratory chemist leads a diverse team of scientists whose goal is to quickly discover materials that can efficiently strip carbon dioxide from a power plant's exhaust, before it leaves the smokestack and contributes to climate change.

DALLAS – May 27, 2010 – For two decades, the laboratory mouse has been the workhorse of biomedical studies and the only mammal whose genes scientists could effectively and reliably manipulate to study human diseases and conditions.
