In the science-fiction movie Gattaca, visitors only clear security if a blood test and readout of their genetic profile matches the sample on file. Now, cheap DNA sequencers and custom software could make real-time DNA-authentication a reality. Researchers at Columbia University and the New York Genome Center have developed a method to quickly and accurately…

Today, implanted electrode devices for stimulating the brain are extremely crude devices with only a handful of electrodes that are used to mitigate the effects of Parkinson’s, epilepsy, and other neurodegenerative conditions. The number of patients with these devices is merely tens of thousands because of the extreme invasiveness of the implantation process and the…

A team of researchers led by Biomedical Engineering Professor Sam Sia has developed a way to manufacture microscale-sized machines from biomaterials that can safely be implanted in the body. Working with hydrogels, which are biocompatible materials that engineers have been studying for decades, Sia has invented a new technique that stacks the soft material in…
