Studying these conditions in animals can only tell us so much, since their diets and immune systems are very different from ours.
Most real estate agents have an especially keen eye for the small details when it comes to homes, and TikToker Eric Goldie is no exception. In his latest post, one such detail catches his attention as he faces the window of a New York apartment all the way across the street from his own, and he kindly gives his neighbors a heads up: "To my neighbors who live on the corner of Bleecker and Perry, um … [camera zooms in on a busy little critter between a window and its blinds] … you have a mouse problem." — Read the rest
A group of scientists just created a mobile cybernetic entity using robotics and the manipulated muscle mass of a dead animal. Neat! Here's the abstract from the paper, titled "Remote control of muscle-driven miniature robots with battery-free wireless optoelectronics," which was recently published in the journal Science Robotics:
