A Japanese brewery, an Okinawan sea sponge and some clever detective work have enabled an international research team based at the University of Chicago to solve a biological mystery, and the solution suggests a novel way to boost the bodys defenses against cancer.
In Science Express, the online early-publication version of the journal Science, the researchers provide evidence that a sugary lipid known as iGb3 plays a key role in regulating the response of natural killer T cells, a component of the immune system that plays an important role in preventing cancer, fighting infections and perhaps triggering or avoiding autoimmune diseases.
Discovered less than ten years ago, natural killer (NK) T cells are unusual because they target lipids, often bound to carbohydrates, rather than proteins. When presented with a lipid that may signal a threat, they pump out chemical signals, such interferon-gamma and interleukin-4, which tell other components of the immune system to rid the body of these invaders.

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...
