Patients with cancer who stop hospice care boost health-care costs

Researchers at Mount Sinai School of Medicine have found that the costs of care for patients with cancer who disenrolled from hospice were nearly five times higher than for patients who remained with hospice. Patients who disenroll from hospice are far more likely to use emergency department care and be hospitalized. The results are published in the October 1 issue of the Journal of Clinical...

Scientists recreate extreme conditions deep in Earth's interior

Scientists have wondered for some time why certain seismic waves travel more quickly through the core-mantle boundary, a thin layer of the Earth's interior that lies between about 1675 and 1800 miles below the surface. Now a new study by Yale University and the University of California, Berkeley sheds light on the mystery by showing how this region behaves under the extreme conditions found so...

Study finds high rate of c-sections after pelvic fractures

In research led by a Saint Louis University surgeon, investigators found that women who give birth after suffering pelvic fractures receive C-sections at more than double normal rates despite the fact that vaginal delivery after such injuries is possible. In addition, women reported lingering, yet often treatable, symptoms following their pelvic fracture injuries, from urinary complications to...

University of Nevada, Reno demonstrates successful sludge-to-power research

Like the little engine that could, the University of Nevada, Reno experiment to transform wastewater sludge to electrical power is chugging along, dwarfed by the million-gallon tanks, pipes and pumps at the Truckee Meadows Water Reclamation Facility where, ultimately, the plant's electrical power could be supplied on-site by the process University researchers are developing.

When it comes to childhood bullying, four key factors help with coping, study says

A new study from researchers at Macquarie University has identified four coping factors that can help children overcome victimisation and lessen the impact of bullying on their future happiness. The report concludes that helping children developing these characteristics can reduce depression, anxiety and behavioural problems when victimised by their peers.

With the use of an open source platform, mobile internet crossing platform barriers

Living in a fast-changing world and always being on the go forces researchers to conceive, develop and bring to market advanced technologies. A case in point is the mobile internet which is growing faster than the blink of an eye. An EU-funded group of experts from mobile web research and industry have joined forces to create an open source (OS) platform and software components that will enable...

U.S. Restricts Controversial Diabetes Pill Avandia

European regulators ordered the diabetes drug Avandia off the market and the Food and Drug Administration placed stringent restrictions on its use in the United States, saying heart attack risks associated with the former blockbuster are too great a safety concern to continue its use for most people. In simultaneous news briefings Thursday, the European Medicines Agency and the U.S. Food and...

Two New Dinosaur Species Discovered in Utah

Scientists said Wednesday they've discovered fossils in the southern Utah desert of two new dinosaur species closely related to the Triceratops, including one with 15 horns on its large head. The discovery of the new plant-eating species -- including Kosmoceratops richardsoni, considered the most ornate-headed dinosaur known to man -- was reported Wednesday in the online scientific journal PLoS...

Study Says Mammograms Are No 'Magic Bullet'

Mammograms don't help women over 50 as much as has been believed, new research suggests. Only a third of the reduced risk of death credited to breast cancer screening is actually deserved -- the rest is due to better treatment and greater awareness of the disease, a large study in Norway found. The research, published in Thursday's New England Journal of Medicine, is the latest to show that...

Malaysia Plans In Vitro for Rhino To Save Species

Malaysian authorities are turning to in vitro fertilization in an attempt to save the rare Borneo Sumatran rhino from extinction, an official said Thursday. The rhino, nicknamed Gelegub, is the only female Borneo Sumatran rhino currently in captivity. But at age 28, she is too old to breed so in vitro fertilization is her last resort, said Sen Nathan, an official with the Sabah Wildlife...

NASA Comet Probe Sends Back First Pictures

A NASA probe heading for a rendezvous with a comet has sent back the first pictures of its target, scientists in California say. The new photo is the first of 64,000 or so NASA's Deep Impact probe is expected to take of comet Hartley 2, the agency said in a release. "Like any tourist who can't wait to get to a destination, we have already begun taking pictures of our comet, Hartley 2," Tim...
