CSAIL researchers crafted a new security scheme that could allow users to run operations on encrypted data without decrypting it first. The approach could be used to protect sensitive data during cloud computation.

Researchers developed a rapid prototyping platform that lets anyone create large-scale, sturdy interactive devices using reconfigurable building blocks. “Once you finish your device, you can just plug it in and it will work,” Miana Smith says.

Engineers have devised a simplified process to convert a skin cell directly into a neuron for cell therapy. The highly efficient method could make it easier to develop treatments for spinal cord injuries or diseases that impair mobility, like ALS.

Air Force engineer and PhD student Randall Pietersen is developing a drone-based system to detect pavement damage and unexploded munitions after an airfield is attacked. “We’re still only prepared to do this on foot, and that’s where my research comes in,” he says.

MIT spinout Boston Metal completed its first run of an industrial reactor that uses electricity to make steel, producing over a ton of metal. While there are still a lot of hurdles left, the latest run shows that the company can scale up its process.
