What is a quantum computer good for? Absolutely nothing — yet

To this day, we have yet to see a quantum computer conclusively perform a single useful task. Existing machines are simply too small and error-ridden to solve commercially relevant problems. That hasn’t stopped Donald Trump’s science adviser from promising a “quantum computer powerful enough for scientific discovery by 2028” and Trump from issuing a new […]

The war against ‘woke’ could end US science as we know it

A sneaky rule change has the potential to blow up scientific research in the United States. But there’s still time to fight it. On May 29th, the Office of Management and Budget (OMB) issued a 412-page proposal to revise federal financial assistance.

ETH Zurich’s bidirectional pixel could turn screens into cameras

A pixel has always done one job. On a screen it emits light to build a picture. In a camera it absorbs light to record one. A team in Switzerland has now made one that does both. Researchers at ETH Zurich have built the first bidirectional pixel, in work published in Nature. The same tiny […]
