Scientists discover the world's oldest color in 1.1 billion year old rock
For millions of years, this popular color dominated the world.
What's the oldest color in the world? Researchers from the U.S., Japan, and Austrailia have been digging in the Sahara desert and have found out that none other than hot pink appears to be the world's oldest surviving color.
No—archelogists didn't uncover the world's oldest H&M. The color is actually the color of the fossils of chlorophyll, discovered in black shale sediment that occurred naturally back when the Sahara was a giant body of water. These particular fossils go back 1.1 billion years where there's a gap in knowledge between how microorganisms became larger animals. The pink was created by cyanobacteria, which was a dominant presence on Earth before algae took over 650 million years ago. Algae helped support larger life, so it's good that these researchers, who published their findings in the journal PNAS, found the dominant food source of life back then.
To keep things in perspective, early humans have only been around about 1.5 million years which is peanuts in the grand scheme of things. Dinosaurs appeared 235 million years ago and were wiped out just 65 million years ago. These cyanobacteria had a great run for 500 million years or so, which is more than enough time to pull off wearing pink.
Perhaps Wednesdays 1.1 billion years ago looked a little something like this:
(Side note: Can you imagine being on a planet with just algae for 100 million years? That's a long, long time of not a lot happening. Ever waited for a public transportation for an hour? Imagine that times 24,000,000,000. Hope you brought a good book or a podcast, amigo.)
Giving our solar system a "slap in the face."
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
The climate change we're witnessing is more dramatic than we might think.
A lazy buzz phrase – 'Is this the new normal?' – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it's worse than that – we're on the road to even more frequent, more extreme events than we saw this year.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
- Morning time again shown not to be the best time to eat.
