Like ancient mariners, ancestors of Prochlorococcus microbes rode out to sea on exoskeleton particles

A new study proposes that ancestors of Prochlorococcus microbes used chitin particles as rafts to venture into the open ocean. This enabled them to evolve new abilities and eventually thrive in the nutrient-poor waters, playing a crucial role in absorbing CO2 from the atmosphere.

Where the sidewalk ends

A new open-source tool called TILE2NET uses aerial imagery and image-recognition to create complete maps of sidewalks and crosswalks. The tool has been trained on 20,000 aerial images from Boston, Cambridge, New York City, and Washington, recognizing 90% or more of all sidewalks and crosswalks in these cities.
