For the first time, a quantum computer has improved its results by continuously correcting its own miscalculations with a technique called quantum error correction. Scientists have long known that quantum computers need error correction to fulfill their potential to solve the problems that hinder standard, “classic” computers (SN: 22.6.20). Quantum computers compute with quantum bits, […]

Flicking the dimmer switch can help some indoor farmers curb one of their biggest challenges: rising electricity costs. Growing crops in stacked rows indoors under fixed-intensity artificial lights can produce more food per square foot using less land and water than traditional outdoor farms. But this vertical farming technique is also energy intensive and expensive […]

But after watching YouTube videos by members of a violent terrorist organization, Yotam Ophir realized that the two groups used similar tactics to connect with distant audiences. The terrorists dressed casually, looked into the camera when they spoke, and recounted their pasts in a […]

For the first time, astronomers have seen gas boiling and bubbling on the surface of a distant star. Scientists observed the red giant star R Doradus with the Atacama Large Millimeter/submillimeter Array, or ALMA, in Chile over four weeks in July and August 2023. The series of images show large cells of gas rising to […]
