While we know how to deliver power wirelessly to stationary objects like implantable medical devices, scientists have tried for years to develop ways to wirelessly charge moving objects. Now, new research in Nature demonstrates a system that can charge an LED light bulb even as it moves away from the power source.

How it works: Using a quantum mechanics concept called parity-time symmetry that describes interactions at the sub-atomic level, a Stanford research team was able to transfer power wirelessly and keep an LED light bulb fully lit for up to one meter as it moved away from the source of power.

What's next: If such a wireless power system can be scaled, it could be developed to deliver power to things like electric vehicles as they're moving along roads.

10 months ago, the Tokyo Olympics were postponed. Now, less than six months ahead of their new start date, the dreaded word is being murmured: "canceled."

Driving the news: The Japanese government has privately concluded that the Games will have to be called off, The Times reports (subscription), citing an unnamed senior government source.

President Biden talks like a soothing centrist. He promises to govern like a soothing centrist. But early moves show that he is keeping his promise to advance a liberal agenda.

Why it matters: Never before has a president done more by executive fiat in such a short period of time than Biden. And those specific actions, coupled with a push for a more progressive slate of regulators and advisers, look more like the Biden of the Democratic primary than the unity-and-restraint Biden of the general election.

Facebook's decision to ask its new independent Oversight Board to review the company's indefinite suspension of former President Trump is likely to set a critical precedent for how the social media giant handles political speech from world leaders.

What they're saying: "I very much hope and can expect … that they will uphold our decision," Facebook's VP of global affairs Nick Clegg tells Axios.
