Panel advises against prostate cancer screening

CNS News

by Lauran Neergaard

October 7, 2011

No major medical group recommends routine PSA blood tests to check men for prostate cancer, and now a government panel is saying they do more harm than good and healthy men should no longer receive the tests as part of routine cancer screening.

The panel's guidelines had long advised men over 75 to forgo the tests and the new recommendation extends that do-not-screen advice to healthy men of all ages. The recommendation by the U.S. Preventive Services Task Force, being made public on Friday, will not come as a surprise to cancer specialists. Yet, most men over 50 have had at least one PSA blood test, the assumption being that finding cancer early is always a good thing. Not so, said Dr. Virginia Moyer of the Baylor College of Medicine, who heads the task force.

Back in June, we announced a pilot program to allow users to surface Google Search data in Google Analytics by linking their Webmaster Tools accounts.

We've been busy making some improvements and tweaks based on user feedback, and today we're excited to make this set of reports available to all users. The Webmaster Tools section contains three reports based on the Webmaster Tools data that we hope will give you a better sense of how your site performs in search results. We've created a new section for these reports called Search Engine Optimization that will live under the Traffic Sources section

When Science Is Wrong: The Threat of 'Truth' by Consensus

The potential derailment of Einstein reminds us of our limitations and man's finite knowledge.

Einstein may have been wrong. New evidence suggests that the speed of light, central to his special theory of relativity, may not be the ultimate speed limit. If the findings hold up, everything we think we know about the inner workings of our universe will need to be revised. This potential discovery reminds us that science is a continual process which is rarely conclusive. That should inform our regard for politicized scientific claims.

Want More Crime in Your City? Close Your Local Medical Marijuana Dispensary

Medicinal (and, ahem, recreational) marijuana aims to soothe, ease, and relax users; take away said users' pot and be prepared to face the consequences.

A report released Tuesday by the RAND Corp., a Santa Monica-based think tank, revealed that after hundreds of medical marijuana dispensaries were forced to close in Los Angeles last year, crime rates rose significantly in nearby neighborhoods. Law enforcement agencies have long been after these dispensaries, arguing that the large amounts of cash are a magnet for thieves, who often go on to resell marijuana. Yet, after what investigators are calling "the most rigorous independent examination of its kind" of LA dispensaries, it appears that the city might need to rethink their position.

NASA's dead satellite falls, starting over Pacific

NASA's dead six-ton satellite fell to Earth early Saturday morning, starting its fiery death plunge somewhere over the vast Pacific Ocean.

Details were still sketchy, but the U.S. Air Force's Joint Space Operations Center and NASA say that the bus-sized satellite first penetrated Earth's atmosphere somewhere over the Pacific Ocean. That doesn't necessarily mean it all fell into the sea. NASA's calculations had predicted that the former climate research satellite would fall over a 500-mile swath.

Scientists discover virus that kills all types of breast cancer 'within seven days'

The virus, known as adeno-associated virus type 2 (AAV2), is naturally occurring and carried by up to 80 percent of humans, but it does not cause any disease.

Researchers learned of its cancer-killing properties in 2005, after Penn State scientists observed it killing cervical cancer cells. They also found that women who carried the AAV2 virus and human papillomavirus (HPV), which causes cervical cancer, had a lower propensity to develop cervical cancer. When combined in a lab recently, AAV2 eradicated all the breast cancer cells "within seven days," according to researchers. Better still, it proved capable of wiping out cancer cells at multiple stages, negating the need for differing treatments used today.

13-Year-Old Looks at Trees, Makes Solar Power Breakthrough

Aidan Dwyer did a much better job on his 7th grade science project than any of us.

While on a wintertime hike in the Catskills, he noticed the branches of trees held a spiral pattern as they ascended. He wondered if that could possibly serve some purpose, looked into it, and learned about the Fibonacci sequence, which is a mathematical way of describing a spiral. Then he studied tree branches more closely and found their leaves adhered to the sequence. Then he figured out that if he arranged solar panels the way an oak tree arranged its leaves, they were 20 to 50 percent more efficient than the standard straight-line solar arrays. That is why the American Museum of Natural History gave him a Young Naturalist award, and published his findings on its website.

Well, if you happen to be in touch with the lovable alien, let him know to load up a few more minutes on his long distance card because SETI is back, on the strength of private donations...
