Physicists calculate exactly how long that last drop takes - Popular Science

Scientists have developed AI tools to measure a person's true "biological age." Live Science asked readers whether they would be comfortable using these tools.

A theoretical calculation estimates roughly 6 × 10⁸⁰ bits of information in selected ordinary-matter particles across the observable universe. The model applies Shannon information theory, assigning an average of 1.509 bits to the particle categories it considers. The study excludes several components and does not establish that information is a new state of matter. An electron’s mass, charge and spin help distinguish it from other particles. Those identifying properties also raise a question: could matter itself be treated as a store of information, and could its information content be counted? The calculation offers one approach to a longstanding problem, rather than a measurement of everything the universe contains. Its result depends on how information is defined, which particles are counted and assumptions about where information can reside.

Archaeologists have discovered a faience workshop at a major temple complex in the ancient Nubian capital of Napata, showing how the rulers of ancient Kush used specialized craft production to reinforce royal power.

More than 99% of the US population lives under light-polluted skies, according to a 2016 study published in Science Advances. With streetlights, brightly lit parking lots, arenas, and passing headlights brightening the night, it can be easy to forget how dark the sky actually is and how many stars appear when you get away from populated areas. Seeing that many stars for the first time can make you pause and remember where you truly are. You are on a rock spinning through space, surrounded by a universe filled with stars, planets, and galaxies larger than anything you can imagine. A remote mountain excursion can combine a dark sky encounter with a day of hiking and sightseeing. After sunset, bright stars emerge above the slopes and ridgelines. These American mountains lie within officially designated dark sky locations that protect natural darkness and the views of the universe it reveals. In northeastern New Mexico, Capulin Volcano sits among volcanic cones, mesas, and buttes in one of the darker areas of the lower 48 states. These landforms help shield the night sky from distant lights, while the rugged terrain has discouraged development in the area.
