Weather satellites have been staring at Earth from 36,000km up for decades. Scientists just realized they can use the same satellites to monitor land temps, drought, and crop health in near real time. Same hardware, second job, zero extra cost. eos.org/science-upda... #Science #GoodNews
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
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
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 2-year study of 15 Australian companies on the four-day work week found: zero productivity drops, six saw output increase, 14 of 15 kept it permanently. Full 100% pay, 80% hours, 100% output. The data is getting hard to argue with. scienceaim.com/australia-ju... #GoodNews #WorkLifeBalance
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
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
A guy in Brazil found a weird glassy rock on his property and sent it to scientists. Turns out it was space glass from a meteorite impact 6.3 million years ago. They found 500+ more pieces nearby. First tektite field found in South America. Curiosity wins. eos.org/articles/sci... #Science #GoodNews
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
Astronomers found a rocky super-Earth in the outer part of a distant star system where rocky planets shouldn't exist according to planetary formation theory. It's the density of iron and silicate rock. Scientists: "anomalous" Universe: still full of surprises. eos.org/articles/the... #Space #Science
