'Pregnant plesiosaur' examined

A paper to be published on August 12, 2011 in Science reveals that Dr. F. Robin O'Keefe of Marshall University in Huntington, W.Va. and Dr. Luis Chiappe, Director of the Natural History Museum's Dinosaur Institute, have determined that a unique specimen now displayed in the Natural History Museum of Los Angeles County is the fossil of an embryonic marine reptile contained within the fossil of its...

Expert tracks illegal online pharmacies

A growing number of illegal online pharmacies are flooding the web trying to sell dangerous unauthorized prescriptions, according to a new report from cybersecurity experts at Carnegie Mellon University.

First death by vampire bat in US

A teenager from Mexico became the first person in the United States to die after being bitten by a vampire bat and infected with rabies, US health authorities said on Thursday.

Regulation of attention and concentration in brain unravelled

(Medical Xpress) -- The prefrontal cortex of the brain is involved in memory processes and the ability to concentrate attentively. Neuroscientists from VU University Amsterdam have shown how and where this occurs in the prefrontal cortex. The research provides insight into how the brain regulates attention and concentration and gives new clues for the treatment of memory problems in elderly...

Samsung, Apple battle goes to Dutch court

A Dutch court will next month decide whether to grant computer giant Apple an injunction in the Netherlands to halt the sale of various smart phones and tablet devices made by South Korean rival Samsung.

Scientists discover how molecular motors go into 'energy save mode'

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets...

Scientists map route for eliciting HIV-neutralizing antibodies

Researchers have traced in detail how certain powerful HIV neutralizing antibodies evolve, a finding that generates vital clues to guide the design of a preventive HIV vaccine, according to a study appearing in Science Express this week. The discoveries were made by a team led by the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID), part of the...

Team finds Type Ia supernovae parents

Type Ia supernovae are violent stellar explosions whose brightness is used to determine distances in the universe. Observing these objects to billions of light years away has led to the discovery that the universe is expanding at an accelerating rate, the foundation for the notion of dark energy. Although all Type Ia supernovae appear to be very similar, astronomers do not know for certain how the...

Team genetically sequences most common bladder cancer

In an article published online this week in Nature Genetics, a University of Colorado Cancer Center team in partnership with universities in China and Denmark reports the first genetic sequencing of urothelial (transitional) carcinoma, the most prevalent type of bladder cancer.

Viacom, Cablevision settle suit over iPad TV app

(AP) -- Cablevision Systems Corp. and Viacom Inc., the owner of MTV and other cable TV channels, have settled a lawsuit over software that lets subscribers view Viacom channels and individual shows on demand on their iPads.

Contact lost with hypersonic glider after launch (AP)

AP - An unmanned hypersonic glider developed for U.S. defense research into super-fast global strike capability was launched atop a rocket early Thursday but contact was lost after the experimental craft began flying on its own, the Defense Advanced Research Projects Agency...

Alcohol consumption in relation to acute pancreatitis

A study on the effect of different alcoholic beverages and drinking behavior on the risk of acute pancreatitis was conducted to study the association between consumption of spirits, wine and beer and the risk of acute pancreatitis. There was no association found between consumption of wine or beer, frequency of alcoholic beverage consumption including spirits, or average total monthly consumption...

Most common bladder cancer tumor sequenced

Scientists have conducted the first ever genetic sequencing of most common bladder cancer. Recognizing the genetic mutations that make bladder cancer cells different than their healthy neighbors may allow early genetic screenings for cancer and new therapies targeting cells with these mutations. In addition, the mutations the team found are similar to those recently discovered in a host of other...
