Sunscreen, while necessary as a skin protectant, has been shown to have an environmentally unfavorable impact. University of Stirling scientists, led by Dr. Sabine Matallana-Surget, studied co-pollution in relation to plastics and sunscreen in the sea, as reported by Phys.org. What they found, shockingly, was that a chemical common to sunscreens could prolong the life of plastic in the water. …

Ordinary matter, also called baryonic matter, consists of protons, neutrons, and electrons. This is the material that emits or absorbs radiation, allowing telescopes to observe stars, nebulae, and galaxies. From the largest galaxy cluster to the smallest grain of dust, everything visible belongs to this category. Yet despite its familiarity, this matter represents only a sliver of the cosmos. It …

Hot cars turn sealed bottles of water into tiny laboratories. A bottle that looks clear can quietly change inside, and what you cannot see still matters. Warmth and light do two things. They help microbes multiply after a single sip, and they also stress the plastic itself, allowing particles and additives to work their way into the water. …

A meta-analysis of “countless” peer-reviewed studies and interviews with dozens of subject matter experts identified a threat that researchers say is as grave as planetary warming is flying frighteningly under our radar, the Guardian reported. What’s happening? “Novel entities” at first may conjure up images of newly established businesses or ghosts, but the concept is more unsettling than an encounter …

IN A NUTSHELL 🌞 Solar storms are causing SpaceX’s Starlink satellites to reenter Earth’s atmosphere sooner than planned. 🚀 The increased atmospheric drag from geomagnetic storms shortens the satellites’ lifespan by 10 to 12 days. ⚠️ A higher risk of satellite collisions emerges due to unpredictable drifts caused by solar activity. 🛰️ Managing a crowded orbit is crucial as more …
