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

Along with knowing about the CARES act provision, the National Council of Nonprofits is urging those who can give to donate so that nonprofits can afford PPE and keep people on staff, to give locally to the small nonprofits near them that need their help, and to look for the nonprofits that have the biggest community impact.

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
The game is enlightening, but also a lot of fun. When I have to be chubby, I puff out my cheeks, jumping from 30% certainty (thanks, quarantine pounds!) to 79% certainty. When I have to be a CEO, I’m passing with only 9% certainty. I’m surprised! I, like most CEOs, am a white man. Wouldn’t that be enough to juice my results? So not knowing what to do, I grimace. That bumps me to 17%. Not quite convincing but, somehow, more convincing than my resting face. … [Read more...] about Can you trick this AI into thinking you’re someone you’re not?
When he served as treasury secretary in the early 1790s, Hamilton lobbied Congress to pass a debt bill that would give the federal government extraordinary financial power by taking over all of the individual states’ debt–a whopping $25 million at the time. Many Southerners opposed the scheme. They saw a dismal future in which the federal government, the wealthy urban elite, and speculators would have all the power. So they voted Hamilton’s proposal down. … [Read more...] about 5 Startup Lessons From America’s First Cofounders
