Washington Heights

Engineers at the University of Washington have developed a tiny jumping robot capable of precisely controlling how high it leaps. The breakthrough could matter for applications where small robots need to navigate uneven terrain or obstacles, such as search-and-rescue or inspection tasks. Details of the mechanism behind the fine jump control have drawn attention across robotics news outlets.

A man in Washington Heights, Manhattan, is cleaning one city block every day for 100 consecutive days, and his effort is drawing neighbors to pick up brooms and bags and join him. What began as one person's daily routine is turning into a small community cleanup movement on his stretch of Upper Manhattan, with residents praising the simple, visible way he is improving the neighborhood.
