While the process to clean wastewater today pulls out everything—including nutrients and essential minerals, not just contaminants—at once, forming a toxic sludge, the new technology, developed as a prototype by a team at the Department of Energy’s Lawrence Berkeley National Laboratory, targets and traps just the copper ions. “It’s kind of like a crystal sponge,” says Jeff Urban, the director of the Inorganic Nanostructures Facility in the Berkeley Lab’s Molecular Foundry and senior author of a new journal article about the technology. “When you put it into water, it opens up. Instead of grabbing everything, this is a sponge that’s very specific to copper because of the size of the pores and the stickiness of the pores for copper.” … [Read more...] about This new tech pulls valuable metals directly from water

Nonprofits are in trouble this year, and not only because the needs they’re serving have skyrocketed, Cohen says. They’re the third largest employer in the country, and as in almost every industry, the pandemic and lockdowns have hit its workforce hard. Before March, nonprofits nationwide employed 12.3 million people—more than airlines or the manufacturing industry. So far into the pandemic, that industry has lost nearly 1 million jobs, and even more are at risk after the money from PPP loans has run out. Nonprofits have added expenses this year too, from all the equipment needed to keep their volunteers safe, such as masks and sanitizer, to the cost of having to transition to online operations. … [Read more...] about Giving Tuesday: Everyone gets a tax break on the first $300 they donate to nonprofits in 2020
But in this regard, as a man, Biden is somewhat unique. Much of his empathy has been born out of a career, as Michael Kruse observes in Politico Magazine, “all but bracketed by tragedy.” In 1972, his wife and baby daughter were killed in a car accident and his two sons, Beau and Hunter, were seriously injured. And in 2015, Beau, who Biden calls “my soul,” died of a rare strain of brain cancer at the age of 46. … [Read more...] about 3 ways gender ‘brain diversity’ can make Joe Biden and Kamala Harris better leaders
In these sliders, McDonald discovered his game mechanic: A meter that shows, in real time, how convinced an algorithm is that you are wearing a mask, have rosy cheeks, or are a CEO. (Yes, all of these are qualities that the AI can supposedly see.) In this way, Facework externalizes the internal work that algorithms do every day. “Because it’s so obscured from view, that’s part of the reason we don’t have well-informed conversations about it,” says McDonald. “For face recognition especially, those systems are kept outside the view of the average person.” … [Read more...] about Can you trick this AI into thinking you’re someone you’re not?
3M leaders believe so strongly in reinvention that they have mandated it. 3M researchers, 8,500-strong, are encouraged to devote 15% of their time–nearly a workday a week–working on whatever they want. If one of those researchers has an innovative idea that their own lab won’t support, they can shop it around to other 3M labs or to apply for a Genesis grant that offers seed money funded by the company. … [Read more...] about 5 Startup Lessons From America’s First Cofounders
