1. This AI app can tell which dinosaur made a footprint

   Dinosaur footprints have always been mysterious, but a new AI app is cracking their secrets. DinoTracker analyzes photos of fossil tracks and predicts which dinosaur made them, with accuracy rivaling human experts. Along the way, it uncovered footprints that look strikingly bird-like—dating back more than 200 million years. That discovery could push the origin of birds much deeper into prehistory.

2. 750-year-old Indian poems reveal a landscape scientists got wrong

   Old Indian poems and folk songs are revealing a surprising truth about the land. Scientists found that descriptions of thorny trees and open grasslands in texts written as far back as the 1200s closely match today’s savannas in western India. This suggests these landscapes are ancient and natural—not ruined forests. The discovery could reshape how conservation and tree-planting efforts are planned.

3. A hidden bat virus is infecting humans

   Researchers in Bangladesh have identified a bat-borne virus, Pteropine orthoreovirus, in patients who were initially suspected of having Nipah virus but tested negative. All had recently consumed raw date-palm sap, a known pathway for bat-related infections. Genetic analysis confirmed live virus in several samples, pointing to active human infection. The finding raises concerns that dangerous bat viruses may be circulating undetected alongside Nipah.

4. Ancient tools in China are forcing scientists to rethink early humans

   Archaeologists in central China have uncovered evidence that early humans were far more inventive than long assumed. Excavations at the Xigou site reveal advanced stone tools, including the earliest known examples of tools fitted with handles in East Asia, dating back as far as 160,000 years. These discoveries show that ancient populations in the region carefully planned, crafted, and adapted their tools to meet changing environments.

5. How gene loss and monogamy built termite mega societies

   Termites did not evolve complex societies by adding new genetic features. Instead, scientists found that they became more social by shedding genes tied to competition and independence. A shift to monogamy removed the need for sperm competition, while food sharing shaped who became workers or future kings and queens. Together, these changes helped termites build colonies that can number in the millions.
