Astronomers probed the cosmic web, a large-scale structure composed of massive filaments of galaxies separated by giant voids. They found the filaments also contained significant amounts of gas, believed to help fuel the galaxies’ growth. Source: https://earthsky.org/space/cosmic-web-gas-reservoir-fuel-galaxies-growth…

Scientists start mapping the hidden web that scaffolds the universe
After counting all the normal, luminous matter in the obvious places of the universe—galaxies, clusters of galaxies and the intergalactic medium—about half of it is still missing. So not only is 85% of the matter in the universe made up of an unknown, invisible substance dubbed “dark matter,” we can’t even find all the small amount of normal matter that should…

Richard Stallman Challenges ‘Misleading’ Coverage of His Comments on Marvin Minsky
Richard Stallman posted a new update today on his personal site. “I want to respond to the misleading media coverage of messages I posted about Marvin Minsky’s association with Jeffrey Epstein.” The coverage totally mischaracterised my statements. Headlines say that I defended Epstein. Nothing could be further from the truth. I’ve called him a “serial rapist”, and said he deserved to…
Scientists detect towering balloon-like feature near Milky Way’s center
It’s a huge bipolar structure, centered on the galactic center and near the central supermassive black hole. In that way, it’s like the Fermi Bubbles, found some years ago. But … there are differences. Source: https://earthsky.org/space/balloon-like-feature-near-milky-way-center…
Ask Slashdot: How Can You Limit the Charging Range of Your Batteries?
“If you’re anything like me, you’ve got a slew of devices with lithium-based batteries in them,” write long-time Slashdot reader weilawei: The conventional wisdom is to cycle them between 20 and 80% for a good compromise between usability and battery life. How then, do you automate the process to avoid over- or undercharging…? Do you remove and store your laptop battery…
