Humans are not alone in suffering the ravages of aging. Cockroaches endure it, too.
Case Western Reserve University researchers reported in the Journal of Experimental Biology that as the roachs life wanes between 60-65 weeks after the onset of adulthood, and the cockroach slows down, experiences stiff joints and has problems climbing and a decreased spontaneous fleeing response. Death comes shortly after the onset of these movement problems.
Angela Ridgel, a post doctoral fellow at Case, was the lead author on the National Institute of Health-funded study, "Effects of aging on behavior and leg kinematics during locomotion in two species of cockroaches." Her research looked at walking, climbing and righting behavior in the roach species, Blaberus discoidalis. She wrote the paper with Roy Ritzmann, professor of biology, and Paul Schaefer, a former Case graduate student who studied escape behavior in Periplaneta americana and contributed information about the roachs central nervous system and escape behavior.

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...
