Washington Heights

Engineers at the University of Washington have developed a tiny jumping robot capable of precisely controlling how high each jump is. The miniature machine adds to a growing field of small-scale robotics, where fine control of locomotion is a key challenge. Coverage highlights the advance as a step toward agile micro-robots that could one day navigate cluttered or hard-to-reach environments.

A man in Manhattan's Washington Heights has spent 100 days cleaning one city block each day, and neighbors have started joining him. The effort has drawn attention as an example of grassroots community action, with locals picking up brooms and trash bags to help keep their streets clean alongside him.
