Ten years ago, Valter Longo had an inkling of a theory of aging that is now challenging the dogma of one of sciences heavyweights – Charles Darwin.
From graduate school to a career as an assistant professor in the USC Leonard Davis School of Gerontology and the USC College of Letters, Arts and Sciences, Longos ideas were questioned by peers and students alike as he explored a new way to look at aging that directly opposes principles set forth by Darwin in his theory of natural selection.
It has long been accepted that natural selection happens on the individual level – the better suited an organism is to its environment, the more likely it is to reproduce, forcing the species to change, or evolve, over time. Longos theory, in contrast, hinges on a process called "group selection," believed by most scientists to be wrong because it proposes that selection happens at the group level rather than the individual .

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
