Abortion Bans Linked to 4.3-Point Rise in Teen Girls’ Suicidal Thoughts
A peer-reviewed study in JAMA Network Open found that states with total abortion bans saw a 4.3-percentage-point increase in suicidal ideation among female high school students after Dobbs — while rates were falling in non-ban states.

Mars Honeycomb Cracks May Be a Frozen Record of Ancient Wet-Dry Cycles
NASA's Curiosity rover has discovered the largest field of honeycomb-shaped polygon fractures ever documented on Mars, and scientists believe the geometry and minerals inside the cracks could reveal how long liquid water cycled across the planet's surface — with direct implications for ancient habitability.
Ancient Smallpox Genomes Show European Colonizers Brought the Virus to Americas
A Trinity College Dublin study recovered the first ancient smallpox genomes from the Western Hemisphere, providing molecular-level proof that European colonizers carried an actively evolving variola virus to the Americas after 1492.
Early Cambrian Fossil Pushes Cephalopod Buoyancy Chamber Back 30 Million Years
A millimeter-scale early Cambrian fossil from South China has revealed the oldest known cephalopod siphuncle — the buoyancy-regulating chamber that launched squid and nautilus ancestors as the ocean's first active predators — pushing that evolutionary milestone back by roughly 30 million years.
California Solar Permitting Gaps: Why Land Use Decides Years of Delay
A new Nature Conservancy and ECOnorthwest study reveals that what land looked like before a permit application is filed is the single strongest predictor of whether a California solar farm clears approval in months or stalls for years. Researchers analyzed over 15 years of county permitting data to close a gap policymakers have long acknowledged but never formally measured.Load More
