We think of mushrooms as food. But mycelium-based blocks could be the future of...
When mushrooms make the news, it's often for grim reasons—a mysterious poisoning, toxic species in the bush, or high-profile court cases.
But the mushroom itself...
Scientists create smart fabrics that defy physics and absorb impact
Most of us expect materials to behave in a familiar way. When you pull on fabric, it stretches longer and becomes thinner.
This is true...
Why the next generation of robots will have tendons instead of motors
At the Soft Robotics Lab at ETH Zurich, the scene looks less like a traditional engineering workshop and more like a child’s playroom mixed...
A simple non-stick trick could make green hydrogen much cheaper
