Researchers developed a workable, solar-powered device that can extract drinkable water directly from the air, even in desert regions.

Why it matters: If the technology can be made commercially viable, it could help alleviate water scarcity in some of the world's driest regions.

What's happening: Researchers at MIT and several other institutions published a paper earlier this week describing how they were able to significantly boost the output of a prototype water-harvesting device.

  • The original design harnessed temperature differences within the device to draw in moisture from the air at night and release it the next day. But its utility was limited because it required specialized and expensive materials called metal organic frameworks.
  • The new design adds a second stage and makes use of a more common material called zeolite, doubling its capacity to generate water.

Details: While other harvesting technologies that can draw water from fog or dew exist, they generally require humidity levels of at least 50%, if not much higher.

  • The new design, by contrast, can work with humidity levels as low as 20%, good enough to operate on an average day in a desert city like Phoenix.

The catch: Even the improved system can still only produce 0.8 liters of water per square meter per day, while humans need at least 2.5 liters per day to survive.

Former Michigan Gov. Rick Snyder charged in Flint water probe

Former Michigan Gov. Rick Snyder (R) was charged with two counts of willful neglect of duty in an investigation into the Flint water crisis, according to Genessee County District Court records and multiple local reports on Wednesday.

Why it matters: Flint saw its drinking water contaminated with high levels of lead in 2014, spurring a public health disaster. The lead-contaminated water was blamed for an outbreak of Legionnaires disease that killed at least 12 people.

Former President Trump filed a $100 million lawsuit against the New York Times and his niece Mary Trump on Tuesday over the news outlet's 2018 reporting on his tax records, the Daily Beast first reported.

Details: The suit, filed in New York's Dutchess County, alleges NYT journalists "engaged in an insidious plot to obtain confidential and highly-sensitive records" and that they "convinced" Mary Trump to "smuggle records out of her attorney's office and turn them over to The Times."

Brazil's health minister tests positive for COVID during UN summit in N.Y.

Brazil's Health Minister Marcelo Queirog has tested positive for COVID-19 while in New York City for the United Nations General Assembly (UNGA), he confirmed Tuesday night.

Why it matters: Hours earlier, Queirog had accompanied Brazilian President Jair Bolsonaro to the UNGA. The Biden administration expressed concern last week that the gathering of world leaders could become a coronavirus "superspreader event."
