Researchers find that one sniff will do for odor discrimination
Rats inhabit a world of smells far beyond our poor powers to discriminate. Thousands of odors that smell the same to us, or that we cannot perceive at all, are quickly recognizable as distinct and meaningful odors to rodents and other animals in which the Nose Knows. But just how quick?
By measuring the speed of smell, researchers at Cold Spring Harbor Laboratory have now found that unlike humans, rats can tell two very similar odors apart with just one sniff. And because its not the Nose that Knows, but rather the brain, such studies of how animals can rapidly and accurately discriminate odors are revealing vital new information about how the human brain processes information, guides behavior, and even enables us to be consciously aware of our own (though less smelly) world, and our own selves.

Researchers Imitate Molecular Crowding in Cells

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...
