One of the most pernicious myths about digital technology is that it is somehow weightless or immaterial. Remember all that early talk about the “paperless” office and “frictionless” transactions? And of course, while our personal electronic devices do use some electricity, compared with the washing machine or the dishwasher, it’s trivial.Belief in this comforting story, however, might not survive an encounter with Kate Crawford’s seminal book, Atlas of AI, or the striking Anatomy of an AI System graphic she composed with…

Reflecting back on late 2021, Denis Villeneuve's Dune had some notable hiccups in its big screen release. That, of course, was the year when theaters were bouncing back after being closed during the COVID-19 pandemic, but the blockbuster film also took a bit of a hit due to Warner Bros.' decision to debut all of their movies simultaneously in cinemas and on streaming. Because of those factors, it was tricky in the runup to Dune: Part Two to figure out exactly how the film would land at the box office... but now it's…

A planet-forming disk with more water than all of Earth’s oceans has been discovered. The disk, which is located in the constellation Taurus, is 450 light-years away from Earth. Astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to zoom in and observe the disk.What they discovered is that the protoplanetary disk around the baby star HL Tauri has more water than all of Earth’s oceans combined. In fact, the water found in the disk could fill the Earth’s oceans a total of three times. The…

Researchers have developed innovative ‘water batteries’ that offer a safe, recyclable alternative to lithium-ion batteries for large-scale energy storage. These aqueous metal-ion batteries use water instead of flammable electrolytes, preventing fire hazards. Their sustainable design facilitates easy disassembly for material reuse or recycling. Significant advancements include overcoming dendrite growth, extending battery lifespan, and achieving competitive energy densities with potential applications in grid storage and…

Boiling and filtering tap water rich in calcium can remove nearly 90% of nano- and microplastics, offering a simple, cost-effective solution to reduce plastic consumption and mitigate environmental pollution. This approach is effective in both hard and soft water, highlighting its potential as a widespread method for purifying drinking water from plastic contaminants. Credit: Eddy ZengNano- and microplastics are seemingly everywhere — water, soil, and the air. While many creative strategies have been attempted to get rid…

It’s not just medicines. A dizzying number of personal care products also end up in the sewers—coconut shampoos and hydrating body washes and expensive face serums and … well, the list goes on and on. Wastewater treatment facilities were never designed to deal with these so-called micropollutants. “For the first 100 years or so of wastewater treatment, you know, the big thing was to prevent infectious diseases,” Wackett says. Today, many wastewater treatment plants mix wastewater and air in a tank to form an activated…

HOOD, Calif. —  In the heart of California, at the place where two great rivers converge beneath the tule fog, lies the linchpin of one of the largest water supply systems in the world.Here in the Sacramento-San Joaquin River Delta, birds soar the Pacific Flyway, cows graze beside sodden rice fields and red reeds poke from still depths. In winter and spring, when the snow melts and the rain pours, water rushes through its sloughs and streams, winding around more than 200 small islands on a path to the Golden Gate and,…
