Scientists have developed a robotic gripping arm that uses engineered bacteria to "taste" for specific chemicals, an advance that may pave the way for biohybrid machines that can sense and interact with the environment around them. The gripper, developed by researchers at the University of California, Davis and Carnegie Mellon University in the US, is a proof-of-concept for biologically-based soft robotics. "Our long-term vision is about building a synthetic microbiota for soft robots that can help with repair, energy generation or biosensing of the environment," said Cheemeng Tan, assistant professor at UC Davis. Soft robotics uses lightweight, flexible and soft materials to create machines that match the versatility of living things, and soft robot designs often draw inspiration form nature. Adding actual living cells to soft robots brings scientists another step closer to creating biological-mechanical hybrid machines. "By combining our work in flexible electronics and robotic … [Read more...] about Robot Arm Can ‘Taste’ Chemicals Using Bacteria

The Chemistry of Cold Packs is a new TED-Ed chemistry lesson. In the short lesson students learn how those cold packs, prevalent in every high school athletic trainer's kit, go from room temperature to near freezing so quickly. The lesson includes explanations of exothermic and endothermic reactions. The questions that follow this lesson are a bit more detailed than those found at the end of many other TED-Ed lessons. The video is embedded below. … [Read more...] about How Do Cold Packs Work?
