Can optical illusions fool AI too?
Deep neural networks (DNN) have made the news recently for their application as a predictive software used to create convincing fake videos of politicians and celebrities. You may not be aware, however, that you have most likely already used the same technology in a much less controversial form: the translation app on…

MIT and newly formed company launch effort to build compact tokamak pilot plant
Development of fusion power, a carbon-free, combustion-free source of energy, is now on a faster track toward realization, thanks to a collaboration between MIT and a new private company, Commonwealth Fusion Systems. CFS will join with MIT to carry out rapid, staged research leading to a new generation of fusion…

In field tests, device harvests water from desert air
You really can extract clean drinking water right from the air, even in the driest of deserts, MIT researchers have found. They’ve demonstrated a real-world version of a water-harvesting system based on metal organic frameworks, or MOFs, that they first described last year.
