3D printing method for polymer features at a resolution of just 10 nanometers and many metamaterial applications

Engineer UK – A novel 3D printing method could allow the creation of polymer features at a resolution of just 10nm, opening up the path to a raft of new metamaterials. ‘Currently, there is no real three-dimensional fabrication method on the nanoscale,’ said lead investigator Joachim Fischer of the Karlsruhe Institute of Technology (KIT). ‘The …

Photon Sieve will make Space Telescopes one thousand times lighter for the same sized collection area

FalconSAT-7 is a 3U CubeSat satellite measuring just 30cmx10cmx10cm. It is a DARPA funded project that is led by Geoff Andersen and colleagues at the US Air Force Academy. They hope to launch a device into orbit in 2014. While not optimized for ground observation, such a telescope would have a 1.8 meter resolution at …

Proposal for a Concept Assessment of a Fission Fragment Rocket Engine (FFRE) Propelled Spacecraft

A new technology, the Fission Fragment Rocket Engine (FFRE), requires small amounts of readily available, energy dense, long lasting fuel, significant thrust at specific impulse of a million seconds, and increases safety by charging the reactor after arrival in LEO. If this study shows the FFRE potential, the return could be immense through savings in …

SENS5 – The impact of PNPASE on the therapeutic potential of mitochondrial RNA import

Researchers have found a mechanism that can be hijacked in order to import RNA into the mitochondria as desired. This work was described as a potential game changer by Aubrey de Grey A decline in the function of mitochondria may contribute to the aging process and age-related disorders. A functional decline could arise from accumulated …
