In 2018, passengers onboard a flight to Australia experienced a terrifying 10-second nosedive when a vortex trailing their plane crossed into the wake of another flight. The collision of these vortices, the airline suspected, created violent turbulence that led to a free fall.
Scientists up to create the next version of Xenobots – tiny biological robots that self-assemble, carry out tasks, and can repair themselves. Now they can move faster and record information.
Researchers developed a machine-learning technique that uses an image to estimate the stresses and strains acting on a material. The advance could accelerate engineers’ design process by eliminating the need to solve complex equations.
