A speculative paper argues that ancient planetary flybys may have helped trigger some of Earth’s mass extinctions. Earth’s history is full of close calls and resets. Life did not move smoothly toward complexity. It survived repeated collapses, including mass extinctions that erased vast numbers of species and changed which branches of life had room to […]
Making the Invisible Visible: $100 Device Detects Cosmic Particles Passing Through You
A pocket-sized particle detector is making cosmic ray physics accessible from classrooms to major experiments. Particles from deep space are passing through the world around you right now. They leave no sound, taste, smell, or sensation, but with the right detector, their arrival can be counted one by one. These particles begin with cosmic rays, […]

Textbooks May Need Rewriting After Researchers Debunk a Core Chemistry Concept
For nearly a century, students have learned the inductive effect the same way. Now, researchers say that explanation may not tell the whole story. For decades, chemistry students have learned the same explanation for how electrons redistribute within molecules. Now, researchers say that lesson may need updating after modern computational analyses challenged one of the […]
Researchers Finally Solve a Decades-Old Mystery About Cellular Aging
A new study identifies the molecular switch that determines when aging cells permanently stop dividing. Every time a human cell divides, the tips of its chromosomes get a little shorter. Those tips, called telomeres, act like protective caps. Once they shrink too far, the cell treats the exposed chromosome ends as DNA damage and stops […]
A Hidden Crisis: Why Millions Are Burning Plastic Just To Survive
New research shows that burning plastic is more common as an everyday energy source than previously understood, raising serious global concerns for health, social inequality, and the environment. For some families, plastic waste is not only something to throw away. It can become fuel for cooking, heat, fire starting, or keeping insects away when safer […]
