Scientists combined a polymer with a carbon catalyst to have sunlight destroys PFAS "forever chemicals" in water. The polymer traps PFAS, light breaks the bonds, out comes harmless fluoride. Works at natural water pH. Still a prototype, but the right kind. eos.org/articles/a-p... #Science #GoodNews

California just broke ground on its first new steel mill in 50 years. It runs on electricity, recycles scrap metal, produces 450k tons of steel a year, and creates ~500 jobs. Clean manufacturing is not a contradiction. www.gov.ca.gov/2025/03/07/c... #GoodNews #California

Japan wired its entire ocean floor fault lines with sensors, to help monitor its nearby subduction zone in real time. Up to 20 extra seconds before a quake, 20 extra minutes before a tsunami. In 2011, some towns had less than 10 minutes. www.scientificamerican.com/article/japa... #GoodNews #Science

The USGS built a free interactive map so you can look up exactly what rocks and sediments are under your feet anywhere in the US. 100+ geologic maps combined, works on your phone, no login needed. Go look up your backyard. eos.org/articles/new... #Science #Geology

Researchers tested 100 years of archived hair and found lead levels in humans today are nearly 100x lower than before the EPA was created. Leaded gas regulations worked. Environmental policy measured in human biology. We actually fixed something. www.pnas.org/doi/epdf/10.... #GoodNews

A superconductivity record that stood since 1993 just got broken. University of Houston physicists pushed a ceramic to 151 K at normal pressure, up from 133 K, using a technique called pressure quenching. Zero-resistance electricity gets one step closer. phys.org/news/2026-03... #Science #GoodNews

Curiosity drove over a rock on Mars, cracked it open, and found pure yellow sulfur crystals never seen there before. Scientists: "It shouldn't be there." Mars: "Surprise." Science is wild. www.sciencealert.com/curiosity-cr... #Space #NASA

Milan built a complete 3D digital twin of its entire 1,575 sq km metro area, accurate to 8mm. City planners can now manage streets, traffic lights, and infrastructure from a screen. This is what smart cities actually look like. www.gim-international.com/content/arti... #Tech #PositiveCuriosities

Dick Van Dyke just turned 100 and his longevity secret is staying positive and never getting angry. Science backs it up. He still goes to the gym 3x a week and dances between machines. Absolute legend. www.sciencealert.com/dick-van-dyk... #GoodNews

Positive News! As a proud Californian (nothing wrong with anywhere else, just love the state I grew up in) I'm happy at the work that's been done in the state. Is there still work to be done? Absolutely. But it's also good to be proud of what you've accomplished. www.youtube.com/watch?v=dwn3...

Positive news! The Biden administration is launching a major initiative to modernize the U.S. power grid. This plan includes updating 100,000 miles of transmission lines and implementing new technologies to improve efficiency and resilience. 1/2

Positive news! MIT researchers have discovered that light can cause water to evaporate without heat, through a phenomenon called the "photomolecular effect." This process involves light photons knocking water molecules loose from the surface, 1/3

A new study shows that plate tectonics may have gotten started because of the impact that caused the formation of our moon. It has long been a geologic mystery as to why plate tectonics started up on our planet and this could be the answer we were looking for.

Los Angeles is employing an AI pilot program to forecast homelessness. The program, developed in collaboration with researchers from the University of Southern California, utilizes data from various sources, including emergency calls, health records, and housing data...

Fact check! Hello everyone! Since America has decided that we apparently are going to live in something that has been dubbed a "post-truth era" (not something that is on Taylor Swift's Eras tour) I feel that we need to add regular fact checking to our positive science stories. 1/8

Cool news: NASA's Europa Clipper mission launched a bit ago to explore Jupiter’s moon Europa. The spacecraft will investigate the icy moon's potential to support life. Equipped with a range of scientific instruments, it will gather data on Europa’s surface, subsurface ocean, and atmosphere. 1/3

Positive news: A new farming robot, the LaserWeeder, uses AI and lasers to target and eliminate up to 200,000 weeds per hour. This reduces the need for chemical herbicides and manual labor, improving crop health and lowering weeding costs by about 80%. 1/2

Positive news: Scientists used AI to identify over 70,000 previously unknown RNA viruses from environmental samples, shedding light on viral diversity. By analyzing genetic data with AI, they discovered these viruses in various habitats, some with unique features like unusually large genomes. 1/3
