Researchers at the National Institute of Standards and Technology (NIST), which is part of the US Department of Commerce, have developed a new technique to 3D print soft objects, such as hydrogels, at a higher resolution than previously possible. The technique uses X-rays or electron beams to crosslink the gels, helping to create complex structures at a nanometer scale. The technique could have the potential in creating engineered tissue constructs for regenerative medicine applications. Soft materials, such as hydrogels, have…

Scientists in Australia are gearing up for clinical trials of a brain implant that may restore limited sight in blind people. Developed at Monash University in Melbourne, the Gennaris system involves bypassing the eye completely and targeting the vision center of the brain. A person would wear a pair of glasses outfitted with a camera that, via a computer, feeds what it is seeing to the brain implant. The wireless implant is positioned on the surface of the brain and…
