I am surprised that they didn’t find micro plastics.

[dougselby]

This seems to suggest that microorganisms laugh at our best "clean" rooms, which is worrying but not surprising.

Preventing sample contamination is a complex problem!

[GilWanderley]

To quote H. G. Wells' War of the Worlds, _"directly these invaders arrived, directly they drank and fed, our microscopic allies began to work their overthrow."_

[charliemopps]

you skipped what I thought was the most interesting part of that study. They WAY they know the organisms didn't come from the asteroid. They calculated the growth rate of the organisms and could show that they were in the process of colonizing the material. They weren't already there... there were very few, and they were quickly consuming what they could and increasing in numbers. So, they weren't there all along, they could see mathematically, that they were in the process of colonizing the material.

This is why surgical implants are never truly sterile and it's so important for hospitals and patients to take their antibiotic protocols seriously.

Dude, I’ve watched your channel for years and I’ll tell you right now. You never cease to find some amazing stuff. I hope you see this, and I hope you’re doing well.!

[roboslug]

My hypothesis is that those bacteria are from California, and they moved to Ryugu because property is so much cheaper there.

[lucash]

I appreciate the non clickbait Anton! Saw numerous news headlines failing to mention they were earth contaminates until way down in the article

[jgcornell]

I'm so glad conclusions of this are sensible rather than hype

Earth organism eats asteroid:

"Mmm this is some serious gourmet shut."

Panspermia may or may not be the case, but Geospermia surely is. Every major asteroid/comet impact on Earth has thrown millions of life-bearing rocks into the void, and many of those have fallen on the other planets of our system, granting each of them a head start in developing their own biosystem. When we finally get our feet off the ground we're going to find Earth-type life all over the place, all perfectly adapted to the various environments of the Solar system.

This could be used as indirect evidence of the quarantine variation of the Fermi paradox. Earth has such an aggressive biology that, if allowed to do so, it would invade and overwhelm any alien ecology it touched.

[ChadsHobies]

I hope you are safe over there in Korea. I heard about something shocking going down in Seoul. Please stay inside until it blows over. Much love for you and your family from my family.

[matusknives]

Well, that sucks, actually. Because if bacteria can contaminate the samples, then anything can. If I were the leading scientist on that project, I would not be particularly pleased.

[LucrataNexarii]

I know it is only a small thing, but thank you for your big grin at the end of your videos. As the world becomes a more tired and hard place (at least for the time), your science videos and good demeanour are always uplifting. Thank you.

Apollo 12 landed on the moon near the Surveyor 3 spacecraft. Pieces of it were brought back to earth, and they found bacteria that had survived more than 2 years on the moon.

[salmanuel]

This finding would make a great TedTalk, and I'd like to see Antonn deliver it in a speech about why investigating near-earth objects should have wide scientific and financial support.

[SpaceWhaIe]

I've worked in Class 10, 000 / ISO 7 clean rooms. They're only as clean and the cleaning crew and occupants keep them. The QA Micro bio teams test them for how clean they are, but even ISO 7 rooms have some tolerance for bacteria/spore counts.

A little unnerving to know this, since this kind of contamination can go both ways. Leaking bacteria/viruses from a lab into the world is pretty risky, and nothing is 100% safe
