How green cities could remove CO₂ from the atmosphere

More than a thousand cities around the world now have "net zero" pledges: they want to emit only as much CO2 into the atmosphere as they can simultaneously recapture. An elaborate meta-study has now summarized the state of ...

People, not design features, make a robot social

It takes a village to nurture social robots. Researchers who develop social robots—ones that people interact with—focus too much on design features and not enough on sociological factors, like human-to-human interactions, ...
