Virtual reality and other technologies offer hope
Posttraumatic stress disorder (PTSD) threatens to overload healthcare and social support systems worldwide as the number of cases rises and existing treatments are not sufficiently effective. New approaches to treatment are relying on technology, such as virtual reality, to alleviate the psychologically damaging effects of PTSD, and these innovative solutions are explored in a special issue of...
'Supra-glacial lakes' are the focus of a new Penn State study
(PhysOrg.com) -- Rising temperatures on the Greenland ice sheet cause the creation of large surface lakes called supra-glacial lakes. Now a Penn State geographer will investigate why these lakes form and their implications.
Compound Shows Promise Against Intractable Heart Failure
(PhysOrg.com) -- A chemical compound found normally in the blood has shown promise in treating and preventing an intractable form of heart failure in a mouse model of the disease, report researchers at the University of Illinois at Chicago College of Medicine.
Computer simulations can be as effective as direct observation at teaching students
Students can learn some science concepts just as well from computers simulations as they do from direct observation, new research suggests.
Google buys ask-your-friends site Aardvark
(AP) -- Google Inc. has bought Aardvark, a free question-and-answer Web service.
LLNL research at Marshall Islands could lead to resettlement
Through Laboratory soil cleanup methods, residents of Bikini, Enjebi and Rongelap Islands - where nuclear tests were conducted on the atolls and in the ocean surrounding them in the 1950s - could have lower radioactive levels than the average background dose for residents in the United States and Europe.
New research eyes off colourful reef fish
(PhysOrg.com) -- Most people wouldn't give a second thought to the inner workings of the fish eye. But research by University of Queensland scientists is unlocking the secrets hidden behind these fishy lenses.
Protecting patients: Study shows that Johns Hopkins flu vaccination rates twice national average
A campaign that makes seasonal flu vaccinations for hospital staff free, convenient, ubiquitous and hard to ignore succeeds fairly well in moving care providers closer to a state of "herd" immunity and protecting patients from possible infection transmitted by health care workers, according to results of a survey at The Johns Hopkins Hospital.
Researchers develop dietary formula that maintains youthful function into old age
Researchers at McMaster University have developed a cocktail of ingredients that forestalls major aspects of the aging process.
Reserchers find new method for manipulating liquid crystals
(PhysOrg.com) -- A new method for manipulating the molecules of liquid crystals in ways previously unachieved could result in more effective industrial sealants, improved food packaging and even enhanced electronic displays, says Zhengdong Cheng, a Texas A&M University assistant professor of chemical engineering and member of a team of researchers whose recent findings hail a significant...
Why Today's Galaxies Don't Make As Many Stars As They Once Did
(PhysOrg.com) -- University of Arizona astronomers have helped solve a mystery surrounding the birth of stars in galaxies that has long puzzled scientists. Their results are published in the Feb. 11 issue of Nature.
Behavioral Therapy Improves Sleep and Lives of Patients with Pain
(PhysOrg.com) -- Cognitive behavioral therapy for insomnia significantly improved sleep for patients with chronic neck or back pain and also reduced the extent to which pain interfered with their daily functioning, according to a study by University of Rochester Medical Center researchers.
Cambridge researchers show Chip and PIN system vulnerable to fraud
(PhysOrg.com) -- Researchers at the University of Cambridge Computer Laboratory have uncovered flaws in the Chip and PIN system that allow criminals to use stolen credit and debit cards without knowing the correct PIN.
Chemists create synthetic 'gene-like' crystals for carbon dioxide capture
UCLA chemists report creating a synthetic "gene" that could capture heat-trapping carbon dioxide emissions, which contribute to global warming, rising sea levels and the increased acidity of oceans.
Dark matter or background noise? Results intriguing but not conclusive
Physicists may have glimpsed a particle that is a leading candidate for mysterious dark matter but say conclusive evidence remains elusive.
Dramatic changes in agriculture needed as world warms and grows, researchers say
The looming threats of global climate change and population growth call for sweeping changes in how the world produces its food and fiber, warns a group of prestigious scientists, including an expert in plant genetics at the University of California, Davis.
Grasping bacterial 'friending' paves the way to disrupt biofilm creation
Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enteric disease.
Inquiry begins into leaked climate emails in Britain
An independent investigation began Thursday into leaked emails from a British climate research centre which appeared to show scientists trying to manipulate the data, and sparked a major global row.

New book examines the flawed human body
Humanity's physical design flaws have long been apparent - we have a blind spot in our vision, for instance, and insufficient room for wisdom teeth - but do the imperfections extend to the genetic level?
New picture of ancient ocean chemistry argues for chemically layered water
A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth's early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet.
New technology won't prevent information security breaches, say ISU experts
(PhysOrg.com) -- The story's become all too familiar in today's digital world. A security breach provides a hacker access to a computer system containing the personal information of 80,000 people.
Research team targets self-cannibalizing cancer cells
A team of scientists from Princeton University and The Cancer Institute of New Jersey has embarked on a major new project to unravel the secret lives of cancer cells that go dormant and self-cannibalize to survive periods of stress. The work may help produce new cancer therapies to stem changes that render cancer cells dangerous and resistant to treatment.
