Brachytherapy reduced death rates in high-risk prostate cancer patients, analysis finds
A population-based analysis looking at almost 13,000 cases revealed that men who received brachytherapy alone or in combination with external beam radiation therapy had significantly reduced mortality rates.

22:26A new position statement issued by the American Academy of Neurology calls on neurologists to begin screening their patients for abusive or violent treatment by family, caretakers or others. Types of abuse include elder abuse, child abuse, sexual abuse, financial abuse, emotional abuse, bullying, cyberbullying and violence.

Blog - Manufacturing is Key to Innovation as Well as Jobs
We need a robust manufacturing sector to create tomorrow's technology.
Suddenly, it seems that manufacturing is again in the news. Or, more precisely, manufacturing and jobs are.

Will Sunscreen Protect You From the Solar Flares? (SPACE.com)
SPACE.com - An explosion in the sun's atmosphere called a "solar flare" sent a huge burst of matter and energy hurtling into space Monday (Jan. 23), and some of the material is now raining down upon Earth. Solar flares are difficult to predict, but they often come in clusters, so more floods of solar radiation are likely to hit Earth soon. -
22:14SPACE.com - If this week's raging solar storm was any indication, the sun is ramping up its activity — and scientists will be ready for it. By meticulously studying our planet's star, they are able to predict these potentially dangerous space weather events better than ever before.

22:05Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years, according to the first published models of Vesta's average global temperatures and illumination by the sun.

22:04NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, shipped to Vandenberg Air Force Base, Calif., on Jan. 24, 2012, to be mated to its Pegasus launch vehicle. The observatory will detect X-rays from objects ranging from our sun to giant black holes billions of light-years away. It is scheduled to launch March 14 from an aircraft operating out of Kwajalein Atoll in the Marshall Islands.

A galactic magnetic field in a lab bolsters astrophysical theory
Why is the universe magnetized? It's a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests. -
21:24Children with autism spectrum disorders (ASD) tend to be fascinated by screen-based technology. A new study by a University of Missouri researcher found that adolescents with autism spend the majority of their free time using non-social media, including television and video-games.

21:24(PhysOrg.com) -- NASA has renamed its newest Earth-observing satellite in honor of the late Verner E. Suomi, a meteorologist at the University of Wisconsin who is recognized widely as "the father of satellite meteorology." The announcement was made Jan. 24 at the annual meeting of the American Meteorological Society in New Orleans.

21:18Your genes could be a strong predictor of whether you stray into a life of crime, according to a new research paper. The study focused on whether genes are likely to cause a person to become a life-course persistent offender, which is characterized by antisocial behavior during childhood that can later progress to violent or serious criminal acts later in life.

21:18Everyone knows a high-school high achiever who has floundered in university. Now researchers may have an explanation for the problem. They say it is likely that some of these students may have undetected reading comprehension difficulties.

21:15A quantum computer based on quantum particles instead of classical bits, can in principle outperform any classical computer. However, it still remains an open question, how fast and how efficient quantum computers really may be able to work. A critical limitation will be given by the velocity with which a quantum signal can spread within a processing unit. For the first time, a group of physicists has succeeded in observing such a process in a solid-state like system.
