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.

How Trump's push to reopen schools could backfire

The Trump administration’s full-steam-ahead push to fully reopen schools this fall is on a collision course with the U.S.' skyrocketing coronavirus caseload and its decades-long neglect of public education.

Why it matters: Getting kids back to school is of paramount importance for children and families, especially low-income ones. But the administration isn’t doing much to make this safer or more feasible.

Coronavirus squeezes the "sandwich generation"

As the coronavirus poses risks and concerns for the youngest and oldest Americans, the generations in the middle are buckling under the increasing strain of having to take care of both.

Why it matters: People that make up the so-called sandwich generations are typically in their 30s, 40s and 50s, and in their prime working years. The increasing family and financial pressures on these workers means complications for employers, too.

Why Scranton matters again in 2020

The hometown of Joe Biden and "The Office" is polishing its perennial status as a guidepost for the nation's political mood.

Driving the news: Biden returns to Scranton, Pa., today with a campaign stop just outside the city limits at a metalworking plant, where he'll deliver remarks on a plan to create jobs and "help America build back better."
