a photo of the ALMA array, a group of radio telescopes with large dishes

A network of telescopes across the globe — including ALMA in Chile (partially shown here) — teamed up to create the Event Horizon Telescope. It’s a virtual radio dish almost as big as Earth.

A short video clip of the OroBOT walking as seen from overhead

Researchers built a robot called OroBOT to re-create the way that Orobates pabsti might have walked. That four-legged creature lived some 290 million years ago.

a photo of a green spiral of cyanobacteria printed onto a white mushroom marked with black graphene ink

Researchers 3-D print a green spiral of cyanobacteria onto a mushroom. The microbes give off electrons when exposed to light. Those electrons flow into the black graphene ink to produce an electric current.
