The common perception is that cancer develops because of gradual mutations over time, finally overwhelming the ability of a cell to control growth.  A look at genomes in prostate cancer found instead that genetic mutations occur in abrupt, periodic bursts, causing complex, large scale reshuffling of DNA driving the development of prostate cancer. 

The researchers dub this process "punctuated cancer evolution," akin to the theory of human evolution that states changes in a species occur in abrupt intervals. After discovering how DNA abnormalities arise in a highly interdependent manner, the researchers named these periodic disruptions in cancer cells that lead to complex genome restructuring "chromoplexy."

School violence has always been an important social issue world-wide because it poses a significant threat to the health, achievement, and well-being of students.

 Chronic myeloid leukemia (CML) is now considered a highly curable disease, thanks to the emergence of powerful, targeted CML therapies known as tyrosine kinase inhibitors (TKIs) that allow patients to manage their disease with few symptoms by taking a well-tolerated pill.

Since the introduction of TKI therapy more than a decade ago, the annual mortality of patients with this disease has declined from 10 to 20 percent in the early 2000s to just 2 percent today and the estimated 10-year survival of CML patients has increased from 20 percent to more than 80 percent.

A paper in Journal of Affective Disorders
found that belief in God was correlated to improved outcomes for those receiving short-term treatment for psychiatric illness.

Dr. David H. Rosmarin, McLean Hospital clinician and instructor in the Department of Psychiatry at Harvard Medical School, examined individuals at the Behavioral Health Partial Hospital program at McLean in an effort to investigate the relationship between patients' level of belief in God, expectations for treatment and actual treatment outcomes.

The segment of society that puts an anti-corporate mentality hand-in-hand with being anti-science is not just on the left; a whole lot of people are now cynical about the goals of the $29 billion organic food industry, especially after their well-publicized effort in California to label GMOs but exempt organic food, alcohol and restaurants. It was regarded as cynical opportunism, a way to get the government to grant their business an opportunity the free market did not.

Surveys show people care more (or less) about the environment based on the economy; if that hierarchy of needs is not being met, people are not worried about who is flying off to global warming conferences, they care about jobs.

Army physician William Beaumont was stationed at Fort Mackinac on Mackinac Island in Michigan in the early 1820s, when it existed to protect the interests of the American Fur Company. The fort became the refuge for a wounded 19-year-old French-Canadian fur trader named Alexis St. Martin when a shotgun went off by accident in the American Fur Company store and duck shot tore into his abdomen at close range June 6th, 1822. 

That accident is key to much of our early knowledge about the workings of the digestive system, say speakers at the Experimental Biology 2013 meeting.
