Bat-Inspired Gripper Lets Drones Perch Like Birds and Switch Off Their Motors

Perching behavior of biological and artificial systems.

A bat hanging from a cave ceiling is doing something that looks effortless but is, mechanically speaking, genuinely strange. It isn’t gripping. Not actively, anyway. When a bat lands inverted, its body weight pulls down on tendons running through the legs, and those tendons tighten the toes around whatever surface the animal has landed on. … Read more

Bat Caves In Cambodia Hide Clues To A Pig Pandemic’s Mysterious Origins

The Battambang bat caves draw tourists from around the world. Each evening, thousands of bats pour from the limestone cliffs in swirling clouds, a spectacle that fills the Cambodian sky. What visitors don’t see is the invisible cargo these flying mammals carry, a sprawling viral universe that researchers are only beginning to map. Between 2020 … Read more

Scientists Turn CO2 Into Fuel Using Hot Water

CO2 conversion diagram

Chinese researchers have achieved complete conversion of carbon dioxide into methane using an inexpensive catalyst in hot water—a process that mimics natural geological phenomena. The team from Shanghai Jiao Tong University developed a honeycomb-structured catalyst made from common metals that transforms 100% of CO2 into methane, a valuable fuel that can be stored and transported … Read more

Ancient Poems Reveal Dramatic Decline of China’s “Smiling” River Porpoise

Poetry from China’s imperial dynasties has unveiled the stark reality of habitat loss for the critically endangered Yangtze finless porpoise, according to new research published Monday in Current Biology. Scientists analyzed 724 ancient poems mentioning the iconic “smiling” porpoise, documenting a 65% range contraction over the past 1,400 years – with most of this decline … Read more

Electric Pulses Train Cockroaches Like Pets

Scientists have discovered a remarkably effective method for teaching cockroaches to navigate mazes, potentially transforming these common insects into valuable search-and-rescue agents for disaster zones. Researchers at Beijing Institute of Technology revealed that gentle electrical stimulation applied to a cockroach’s cerci—sensory organs on their rear end—not only steers their movement but also helps form strong … Read more

Mice Show Empathy, Help Unconscious Friends

AI generated image of lab mouse CPR

Scientists have discovered that mice naturally help their unconscious companions without any training or rewards, challenging long-held assumptions about animal altruism and revealing surprising parallels between rodent and human social behavior. When placed near an anesthetized mouse, observer mice show clear signs of distress and quickly begin grooming and licking their unconscious companions. This behavior … Read more
