1. Toxic “forever chemicals” found in 95% of beers tested in the U.S.

   Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water contamination. The findings reveal how pollution in municipal water supplies can infiltrate popular products, raising concerns for both consumers and brewers.

2. Tiny skaters beneath the arctic ice rewrite the limits of life

   Hidden within Arctic ice, diatoms are proving to be anything but dormant. New Stanford research shows these glass-walled algae glide through frozen channels at record-breaking subzero temperatures, powered by mucus-like ropes and molecular motors. Their astonishing resilience raises questions about how life adapts in extreme conditions and highlights the urgency of studying polar ecosystems before they vanish.

3. NASA spacecraft detect a mysterious force shaping the solar wind

   NASA’s Magnetospheric Multiscale Mission has uncovered surprising behavior of pickup ions drifting through the solar wind near Earth. These particles, once thought to be minor players, appear capable of generating waves and influencing how the solar wind heats and evolves. If true, it could force scientists to revise models of solar system dynamics, with implications reaching all the way to the edge of the heliosphere.

4. Secrets unearthed: Women and children buried with stone tools

   Archaeologists studying the vast Zvejnieki cemetery in Latvia have uncovered surprising truths about Stone Age life. Stone tools, long thought to symbolize male hunters, were actually buried just as often with women, children, and elders. Some were deliberately crafted and broken as part of funerary rituals, revealing a symbolic and emotional dimension to these objects. The research overturns stereotypes about gender roles in prehistory and shows how simple tools carried profound meaning in life and death.

5. These dinosaur eggs survived 85 million years. What they reveal is wild

   Dating dinosaur eggs has always been tricky because traditional methods rely on surrounding rocks or minerals that may have shifted over time. Now, for the first time, scientists have directly dated dinosaur eggs by firing lasers at tiny eggshell fragments. The technique revealed that fossils in central China are about 85 million years old, placing them in the late Cretaceous period. This breakthrough not only sharpens our timeline of dinosaur history but also offers fresh clues about ancient populations and the climate they lived in.
