A new biohybrid fish swims using human heart cells beating in its tail

Robotics

Biohybrid fish powered by beating human heart cells swims for 100 days

Researchers at Harvard and Emory have created a biohybrid fish out of human heart cells that swims autonomously for months at a time as the cells beat. The project is a sidestep on the way to eventually growing new functional hearts for transplant.

Researchers have developed a device that makes climbing stairs easier, by storing energy from a user's descent and giving it back to help people on the way up

Architecture

Energy-recycling stairs put a spring in each step

Climbing stairs is a chore that's inspired some creative alternatives. Now a team from Georgia Tech and Emory University has developed energy-recycling stairs that take some of the pressure off the knees and ankles, by storing energy from people descending then giving it back as they climb up.

Researchers from Bristol University have developed hit predicting software
