In a groundbreaking discovery, researchers have found that crows possess the remarkable ability to count using vocalizations. A study published in the journal Science revealed that carrion crows can flexibly produce variable numbers of one to four caws in response to arbitrary cues associated with numerical values. This finding challenges previous notions of animal cognition…

Researchers from the University of Cambridge have developed eco-friendly, adaptive sensors made from “electronic spider silk,” which can be printed directly onto biological surfaces like skin or flower petals. These sensors are ultra-lightweight, imperceptible, and enable continuous health monitoring without obstructing natural sensations. The method is low-waste and low-emission, making it versatile for applications in…
