Research led by biologists at the University of California, Berkeley, has found that damage to a cells DNA sets off a chain reaction that leads to the increased expression of a marker recognized by the bodys immune system.
The new findings, to be published July 3 in an advanced online issue of Nature, shed light on a long-standing question of how the natural killer (NK) cells - which are able to attack tumors - can differentiate cells that are cancerous from those that are healthy.
"Our study is the first to show that there are mechanisms in place for the immune system to identify cancer cells," said Stephan Gasser, UC Berkeley post-doctoral researcher in molecular and cell biology and lead author of the paper. "It reveals how natural killer cells distinguish something theyre supposed to get rid of versus something theyre supposed to keep."

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
