Robotic Ray with Rodent Cells

By Kate Stone Yes, researchers have finally created one of the things we have all been waiting for: A swimming robotic ray. Not an RC Car This isn’t a rubber stingray that works like a radio-controlled car or a programmable rover. This robotic stingray is powered and guided by light-sensitive rat-heart cells. Yes, you read that correctly. The project demonstrated a new method for building bio-inspired robots by means of tissue engineering. Batoid fish, such as stingrays, are recognizable by their flat bodies and long, wide, winglike fins. These fins…

Cooling Electronics with Graphene-based Film

How many fans does it take to keep your computer from overheating? Electronic systems accumulate a great deal of heat, mostly due to the ever-increasing demand on functionality. Computer users have been using cool air (and even liquid) to reduce heat, but now researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. The film is a mere 20 micrometers thick, yet has four times the thermal conductivity capacity of copper. Cooling Electronics, Protecting the Environment Getting rid of excess heat in efficient…
