Research carried out by veterinary scientists at the Royal Veterinary College reveals that deer antler regeneration may use stem cells and involves similar mechanisms to those used in limb development. The research could take us towards a ‘holy grail’ in human medicine: the ability to restore organs damaged through trauma, disease, cancer or excision.
Many lower animals such as newts can renew damaged parts of their bodies but antler growth is the only example of mammals being able to regrow large complex organs.
Deer antlers are large structures made of bone that annually grow, die, are shed and then regenerate. Although dead tissue when used for fighting, during growth they consist of living bone, cartilage blood vessels and fibrous tissue covered in skin.

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...
