There's something highly unsettling about this microbiologist's deep dive into how lobsters are basically immortal sea scorpion monsters that have immortality interwoven in there DNA.

Neil DeGrasse Tyson made a lot of people (and presumably ducks, cats and bedbugs) angry with a much less than true fact about sex and evolution. His claim, that sex doesn't hurt any species had many Twitter users jumping to correct him.

And you might be thinking, he's just trying to be positive about human sexuality and say, in his own pseudoscientific way that it's healthy and painless for humans. But... that's actually not true either:

Sure, he's a scientist but cut him some slack, he's not that kind of scientist. He studied astrophysics, how's he supposed to check his facts at all before Tweeting about biology?

What you're seeing is a bloom of phytoplankton in the North Atlantic Ocean. These microscopic organisms are very important to the environment and might even influence clouds and the climate.
This image was taken by the Suomi NPP satellite. Data from chlorophyll in the phytoplankton was combined with red, green and blue bands from the satellite's imaging system to make this picture. The mission of the satellite is to keep track of climate change and weather.
It's also pretty good at taking amazing pictures of Earth.
Some images taken from the satellite look a lot more like weather forecasts than gorgeous water colors but the phytoplankton blooms are actually a pretty normal occurrence.
