Researchers can prod stem cells into forming heart-like beating clumps in the lab, but those cells don't behave normally. To get them to mimic normal adult cells requires tension and a specific shape.
By solving how whooper swans keep their heads steady during flight, Stanford engineers have developed a camera suspension system that could allow drones to produce crisper video images.
Silicon can catch photons and convert energy into electron flows. New research shows that a little stretching could give one of silicon's lesser-known cousins its own place in the sun.
