Ancient Smallpox Genomes Suggest the Virus Grew Deadlier Over Time
Researchers sequencing variola virus DNA from medieval remains found ancient smallpox strains genetically distinct from the modern virus — and possibly less deadly. The findings suggest smallpox evolved its catastrophic lethality relatively late in history.
245-Million-Year-Old Fossil Still Has Its Liver — Inside a Triassic Sea Reptile
Researchers studying a 245-million-year-old fossil of the Triassic marine reptile Austronaga minuta found its liver, stomach, and intestines still intact — a vanishingly rare case of soft-tissue preservation that is rewriting what fossils can hold.
167-Million-Year-Old Snake Fossil Rewrites When Legs Were Lost
The discovery of Breugnathair elgolensis, dated to roughly 167 million years ago, is forcing paleontologists to push back the origin of the snake body plan into the Jurassic Period — and paired with other rare finds, it's reigniting debate over why limblessness evolved at all.
Each 10% Refined Carb Increase Cuts Healthy Aging Odds by 13%
New research tracking women over time found that every 10% increase in refined carbohydrate intake reduced the odds of healthy aging by 13%, while swapping in high-quality carbs — measured by fiber content, glycemic load, and fermentability — improved outcomes across physical, cognitive, and metabolic health.
BTK Inhibitor Resistance: How Blood Cancers Bypass Even Next-Gen Drugs
Scientists have identified a rare mutation that enables blood cancer cells to evade both first- and next-generation BTK inhibitors by reducing their dependence on the BTK protein itself—a fundamentally different escape route than previously documented.
Jurassic World Rebirth’s Dinosaurs: What the Science Actually Gets Right
From T. rex as an active predator to the 65-ton Dreadnoughtus, Jurassic World Rebirth gets more paleontology right than you'd expect — even as its core DNA premise remains scientifically impossible.Load More
