Faster engine for powering insect-sized robots

Spotted: Researchers at the University of Washington have developed a more efficient way to power miniature robots. The researchers use electrohydrodynamic (EHD) thrust, which requires no moving mechanical parts. EHD is similar to ion propulsion used in solar-powered spacecrafts.  Ion propulsion systems work by bombarding xenon atoms with electrons, which gives them a positive charge…

Scientists develop 3D bioprinting method for medical assistance in space

Scientists at Germany’s University Hospital Dresden (TUD) have developed 3D technology to print skin and bones in space. The project, sponsored by the European Space Agency (ESA), could allow astronauts to receive treatment when needed and without having to return to Earth, according to the scientists. The method involves using human blood as a “bio-ink”…
