Writing for IEEE Spectrum, David Wagman spotlights a new technology from MIT researchers that could offer water-scarce cities, “a new source of the precious resource” by capturing and reusing water from cooling towers. Prof. Kripa Varanasi notes that their system, “can achieve on the order of 99 percent efficiency,” in capturing the water droplets.

Using magnetic nanoparticles that have been mixed into rubber, Associate Prof. Xuanhe Zhao has created “3D printed shapes that fold, morph, and move in the presence of a magnetic field,” reports Leah Crane for New Scientist. In the future, Zhao believes this work could have medical applications, “like assisting minimally invasive surgeries,” notes Crane.

In an article for The New York Times, Prof. Vipin Narang writes that President Donald Trump’s meeting with Kim Jong-un of North Korea legitimized North Korea’s status as one of the world’s nuclear powers. “North Korea’s nuclear power is politically complete, thanks to the legitimacy that comes from a handshake with an American president,” argues Narang.

MIT researchers have discovered that probiotics can prevent cholera and treat early stage cases of the disease, reports Laney Ruckstuhl for The Boston Globe. The findings, led by Prof. James Collins, “could have implications for other diseases as well because scientists were previously unaware that bacterial infections could be vulnerable to naturally occurring probiotics,” notes Ruckstuhl.
