New Portable Device Can Turn Saltwater Into Drinking Water

Only 0.5% of Earth’s 326 million trillion gallons of water is safe to drink. To make water more accessible and consumable, researchers at MIT developed a portable device that converts saltwater into drinking water with the touch of a button. The current prototype (which fits into a regular-sized suitcase) requires less power to operate than a cellphone charger, processes one liter of water per hour, …

The Ionic Wind Aircraft Flies Without Moving Parts

A team of MIT engineers, led by Steven Barrett (an associate professor of aeronautics and astronautics at the academic institution), have invented the Ionic Wind Aircraft—a first-of-its-kind flying vessel that employs no moving turbines or propellers. Rather, the craft’s flight is sustained by an “ionic wind” (aka electroaerodynamic thrust) produced when a current passes between thin (positively charged) and thick (negatively charged) electrodes onboard. Lithium-polymer …

The Most Accurate Virtual Representation of the Universe’s Evolution Helmed by the University of Helsinki, a simulation named “Sibelius-Dark” produced the most accurate virtual representation of the universe’s development to date. It captures the Big Bang to the present, reproducing the entire evolution of our section of the cosmos. Using the DiRAC COSmology MAchine (COSMA), scientists found one patch of our universe to be unusual, …
