By Katie Hunt, CNN (CNN) — The earliest dinosaurs were unremarkable, bit players on a supercontinent crowded with other ancient reptiles when they first evolved around 230 million years ago. Fast-forward 30 million years, however, and dinosaurs dominated the planet, coming in all shapes, sizes and forms, while many of their reptilian counterparts had died

By Mindy Weisberger, CNN (CNN) — An odd little gourd called the squirting cucumber has an explosive reproductive strategy that has intrigued naturalists since the days of the Roman Empire. Squirting cucumbers blast their seeds over distances hundreds of times their length, and now scientists know how the plants do it. A squirting cucumber in

By Ashley Strickland, CNN (CNN) — Researchers have discovered the residues of psychedelic drugs, bodily fluids and alcohol inside a 2,000-year-old mug, suggesting that ancient Egyptians imbibed hallucinogenic beverages during rituals. It’s the first time scientists have been able to identify chemical signatures of the liquid concoctions sipped from mugs decorated with the head of

By Jackie Wattles, CNN (CNN) — Russian cosmonauts on the International Space Station were forced to briefly lock down a segment of the orbiting laboratory this weekend after finding an “unusual odor” emanating from a visiting cargo spacecraft called Progress 90, NASA said Sunday.
