Study finds phone use on the toilet may cause painful medical condition - Science Daily

Every time you go to the toilet, you could be flushing away a valuable resource – your urine. Today, we see urine as a waste product – but that wasn’t always the case. Historically, it was a highly valued commodity, used to dye cloth, tan leather and make gunpowder. Roman writer Pliny the Elder even recommended people use it to whiten their teeth (though don’t try that one at home).

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.

Here is SpacePolicyOnline.com’s list of space policy events for the week of October 18-24, 2026 and any insight we can offer about them. The House and Senate are in recess, except for pro forma sessions, until after the midterm elections. This week has two especially interesting events — the launch of JAXA’s Martian Moons eXploration (MMX) mission tomorrow (Monday) afternoon EDT, and a NASA update on the Artemis program on Friday — plus many others. We’re also keeping track of the discussions on social media about the very close approach of Russia’s Kosmos 2612 to the U. S.-registered ICEYE X36 Synthetic Aperture Radar (SAR) satellite.
