 Tech giants are racing to ward off a carbon time bomb caused by the massive data centers they're building around the world.A technique pioneered by Google is gaining currency as more power-hungry artificial intelligence comes online: Using software to hunt for clean electricity in parts of the world with excess sun and wind on the grid, then ramping up data center operations there. Doing so could cut carbon and costs. There's an urgent need to figure out how to run data centers in ways that maximize renewable energy…

The Current24:29Will lab-grown meat ever reach our plates?Read transcribed audio.What's cultivated, meat-like, and could help lower greenhouse gas emissions? Lab-grown meat — and it could be the future of protein.Sometimes known as cultured meat, lab-grown meat is unlike plant-based alternatives from companies such as Beyond Meat or Impossible Foods. Instead, it's made by taking a few stem cells from an animal's muscle, then placing them in a nutrient broth where they multiply and are triggered to turn into muscle…

Zipping around the city by personal jet pack is still just a dream, but a drone humming along to drop off groceries, prescriptions or a late-night pizza at your door could become a reality in the Denver area as soon as late spring. Drone Express, which moved its headquarters to Denver in November, is one of a handful of companies to earn a spot in the Federal Aviation Administration program focused on incorporating drones into the national airspace and authorizing their use for commercial services. Within the next few…

Every gram counts in commercial flight. Material scientists from Kobe University have discovered “nanospheres” that are near-invisible silicone crystals. The particles can reflect light thanks to very large and efficient scattering, research published in the ACS Applied Nano Matter journal details. The result could mean covering a surface in vibrant color while only adding 10 percent of the weight of painting an aircraft for the same effect.Minoru and Hiroshi’s discovery focuses on structural rather than pigment color to…

Paint might not seem like the heaviest component to consider when building a large device like an airplane, but its mass can add up. Now, a new and lightweight substance could provide a welcome substitute: Two material scientists from Kobe University, Fujii Minoru and Sugimoto Hiroshi, have discovered nanospheres that are near-invisible silicone crystals. The particles can reflect light thanks to very large and efficient scattering, research published in the journal of ACS Applied Nano Matter details. The result could…

Credit: Unsplash/CC0 Public Domain The annual rate of carbon emissions due to the degradation of carbon stocks in mangrove forests is predicted to rise by nearly 50,000% by the end of the century, according to a new study published in Environmental Research Letters. Mangroves in regions such as southern India, southeastern China, Singapore and eastern Australia are particularly affected. …

Colorado-born Ball Aerospace has a new owner, a new name and what the company hopes will be a growing global customer base. But Dave Kaufman, president of the company now called Space & Mission Systems, said the nearly 70-year-old business is “staying put” in Colorado. BAE Systems PLC, a British arms, security and aerospace company, closed the $5.5 billion acquisition of Ball Aerospace from Ball Corp. on Friday, Feb. 16. Kaufman, previously Ball Aerospace president and a Ball Corp. senior vice president, removed a…

The Biden administration plans to loosen the limits on tailpipe emissions proposed last year by the Environmental Protection Agency (EPA), giving automakers more time before they’ll be required to sell significantly more electric vehicles than gas-powered cars, reported this weekend. Under the , EVs would have to account for 67 percent of new car and light-duty truck sales by 2032.Rather than forcing manufacturers to start ramping up EV sales right away, the changes would allow them to make the shift more gradually…
