Rick and Morty has always been a joint endeavor between Community co-creator Dan Harmon and Justin Roiland, but now that partnership is at an end. Ahead of Season 7, Adult Swim released a statement on Twitter announcing that it had severed all ties with Justin Roiland, and that his roles in multiple shows will be recast.

This follows Roiland being charged with felony domestic violence, multiple allegations of misconduct being raised, and the leaking of inappropriate DMs Roiland sent to minors. Adult Swim, to its credit, did not hesitate to make the obvious and correct decision.

Millions of years ago, countless massive plant-eating creatures known as megaherbivores roamed the planet’s rainforests during the Pleistocene era.

Today, elephants are among the last surviving megaherbivores in rainforests. According to new research, these tropical forest elephants likely have “profound” effects on forest ecosystems — and may be an overlooked climate change solution. The findings were published Monday in the journal Proceedings of the National Academy of Sciences.

The first astronauts who venture to Mars may make at least one leg of the trip on nuclear power, if NASA and DARPA succeed in their most recent joint venture.

DARPA wants a rocket that will let it maneuver its hypothetical spacecraft freely and quickly in space around Earth. NASA wants a rocket that can get astronauts to and from Mars faster and with less fuel. They’ve found a common solution: nuclear thermal propulsion.
