Key Discoveries
How Wildfires and Volcanoes Pump Stratospheric Water Vapor into the Sky
Scientists discovered that moderate volcanic eruptions and extreme wildfires have injected millions of tonnes of water vapour into the stratosphere since 2005. This unexpected moisture influx offsets previous drying trends and alters our understanding of climate drivers. Future climate projections must now account for these aerosol-driven atmospheric changes.
Spotting the Typo: Why We Need Smarter Spinal Muscular Atrophy Genetic Testing
Detecting spinal muscular atrophy (SMA) is difficult because the responsible gene closely mirrors a nearby neighbour. Researchers successfully tested a specialised algorithm on 490,000 genomes to accurately distinguish between these genes. This tool could make population-level genetic screening highly accurate with virtually zero false positives.
Why the Chemical Recycling of Plastics Just Got a Massive Upgrade
Scientists have developed a highly efficient zinc catalyst that cleanly dismantles common plastics back into their original building blocks. This process can recycle up to 43 kilograms of polymer per hour with microwave assistance, maintaining 99% selectivity. This development suggests a future where commercial plastics can be recycled infinitely without losing strength.
