Absolutely incredible.
NASA Astronaut Reid Wiseman, who commanded Artemis II, took this footage from the far side of the Moon with his iPhone.
Watch with sound on.

This may be the stupidest climate denial talking point of all time
Join us in Montreal for the Canada/US Northeast hub!
I will give a talk and @gmdouglas.bsky.social @nagissa.bsky.social & Tim Blower will surely give *great talks*
Opportunities for student talks and posters and a good time guaranteed!
Grab a coffee and enjoy reading up on CO metabolism in methanotrophs!

Big thanks to our collaborators at QUT!

"Planet Earth: You. Are. A. Crew."
Artemis II mission specialist Christina Koch reflects on what it means to be a "crew."
🚨 Why can’t mammals regenerate limbs like frog tadpoles or salamanders?
In our new paper in @science.org , we show that species-specific oxygen sensing acts as a gatekeeper for initiating limb regeneration 🐭🐸

Earthset captured through the Orion spacecraft window at 6:41 p.m. EDT, April 6, 2026, during the Artemis II crew’s flyby of the Moon. A muted blue Earth with bright white clouds sets behind the cratered lunar surface. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater has terraced edges and a flat floor interrupted by central peaks. Central peaks form in complex craters when the lunar surface, liquefied on impact, splashes upwards during the crater’s formation. [alt text from NASA]
#Artemis II lunar flyby images are showing up! 😍

What electron microscope images hint at, but can only be seen in videos: how 'Asgard' archaea move.
New paper in mSystems! 🧵 - how much of your metagenome is actually bacterial/archaeal DNA? For many samples, nobody knows.
We built SingleM prokaryotic_fraction (SPF) to answer this, then ran it on >100,000 public metagenomes. 🧬🖥️🦠
Here's what we found 👇

I ❤️ this @theglobeandmail.com piece on @gdwantibiotics.bsky.social. Such a beautiful story about his drive to discover new antibiotics against all odds, a tribute to his global leadership, not to mention the many trainee careers he has launched. So honoured to have been hired by this great man. #AMR
Anyone who says that has not been to Yellowstone NP.

Chair in Earth Sciences position @uniofstandrews.bsky.social closing soon - Monday 23 March.
Very broad remit, so if you’d like to join our lovely school, and get to live in the super beautiful and friendly wee nation of Scotland, please apply!

New paper out! We sat down and compiled all viral work in marine sediments. The water column has been getting a second look for viral interactions, its time for sediment to have the same!

Check out our new paper on how temperature modulates the iron requirement of nitrifying bacteria - these guys are critical in the ocean nitrogen cycle as they recycle oxidised forms of N. But to do this they need a lot of iron. 🌊

Ahhh yes, the geopolitical version of champagne: if it’s not officially declared, it’s just a sparkling military operation.
Thrilled to share that our preprint has been accepted in Science Advances! Grateful to an incredible team & collaborators.

That's correct...not a mass extinction. The paper you shared describes a potential decrease in primary productivity, meaning reduced growth of photosynthetic microbes in the surface ocean.
If you ever want to read a paper for free and can't find it otherwise, email the lead author and politely ask for a copy. You will not be bothering the person. You will in fact make their whole entire day. I have had scientists get so excited I asked they sent me everything they ever published.
Alex, the answer is: what is creating new terrorist groups?
Much of the anaerobic microbial life was not wiped out by the GOE…particularly on the time scale of the oxygenation which occurred over hundreds of millions of years. Those anaerobic microbes just moved to deeper parts of the ocean which remained anoxic for while after the GOE.
Yikes.
In collaboration with @aslo.org , @tosoceanography.bsky.social, we thank you for a successful #OSM26!
See you at #OSM28 27 February–3 March, Vancouver, Canada 🇨🇦!

The trove of files released by the Department of Justice, illuminates Epstein’s deep interest and entrenchment in the scientific community.
But the files also underscore how he used his power and money in ways that kept women out of places where they might succeed. https://bit.ly/4qWgPLz
The Epstein files document what many women researchers have long experienced but rarely seen laid bare so starkly: exclusion operating behind closed doors, shaping who gets funded, invited, mentored, and taken seriously. How many of these networks, norms, and gatekeepers remain in place?
Scientists have seen Asgard archaea crawling for the first time. When it comes to the origin of eukaryotes, this is like seeing a feathered dinosaur in the wild. (Video courtesy of Philipp Ralder)

One of the biggest questions in biology is how complex cells evolved about 2 billion years ago. Here's my new story on how scientists are solving the mystery of eukaryotes like us. Gift link: nyti.ms/4qMbo22
Come work with us on #darkoxygen as part of the NASA Postdoctoral Fellowship Program. It is an amazing opportunity to get up to 3 years of funding. Deadlines are March 1. and November 1. Happy to discuss your ideas! Details here: zintellect.com/Opportunity/...
