New device creates water from air

UK Department for International Development

Scientists have developed a way to pull water out of air in arid settings, powered by nothing more than sunlight. This is a big deal for fighting water scarcity, a problem faced by more than half the world, and it matters even more because it can work in impoverished low-humidity environments.

How it works: During the day, sunlight hits porous materials in the device, creating just enough energy to convert water molecules into vapor. The prototype isn't yet ready to be scaled for broad use, but the teams that developed it at MIT and the University of California-Berkeley believe that it shouldn't take long to test it in arid countries around the world.

Sound smart: The device is built on synthetic, porous materials (called metal-organic frameworks) made of molecules held together with metal atoms.

George Floyd updates

Thousands are gathering for a day of protests in Washington, D.C., almost two weeks after George Floyd's killing. Protesters in Australia and Europe staged anti-racism demonstrations on Saturday as well.

What's happening: A memorial service for Floyd is taking place in Raeford, North Carolina — near where he was born. Gov. Roy Cooper ordered all flags to fly at half-staff to honor Floyd until sunset. Thousands of demonstrators have gathered in Philadelphia and Chicago.

Buffalo police officers arrested after shoving 75-year-old protester

Two Buffalo police officers were charged with assault on Saturday after a video emerged of them shoving a 75-year-old protester while clearing a demonstration in the wake of George Floyd's killing, AP reports, citing prosecutors.

The state of play: Both officers pleaded not guilty to second-degree assault, and were released without bail. After the law enforcement officers were initially suspended without pay on Friday, all 57 officers on the Buffalo Police Department's Emergency Response Team resigned in a show of support for their fellow officers' suspensions.
