...many such changes associated with autism, most are very rare. This paper, however, found an intriguing pattern among two genes already linked to autism and nine newly identified targets. Most play a role in two key systems in the brain. One is the same brain-wiring system - neural cell adhesion - implicated in the first paper. The second is a set of housekeeping proteins - the ubiquitin system - that whisk away old brain connections and set the stage for new ones...

Kassis’ test looks to circulating tumor cells—any tumor, no matter how small, sheds tumor cells into the bloodstream. These cells typically die on their own, and are cleaned up by phagocytes—a type of white blood cell. The test examines whether markers of ingested tumor cells are detectable in the patient’s phagocytes. The results are then compared to an non-phagocytic white blood cells, such as lymphocytes. Kassis said that he conceived of this approach due to his background in immunology. While this field is typically far removed from radiology...

The previous year, he followed his party in supporting a bill to halt restrictions on federal spending on embryonic stem cell research. He also showed an independent streak: Even as much of Alabama's Democratic establishment, including its black caucus, backed then-Sen. Hillary Clinton in the state's Democratic presidential primary, Davis endorsed Obama. (Obama won.) In the days after Obama's victory last November, there was talk that Davis...

Communists rail against his introduction of testing of public-school teachers. "Correa isn't stupid," says analyst Margarita Andrade at Analytica Investments in Quito...
