Cultivating the Ancestors… in Motion 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 👇 doi.org/10.1128/msystems.01062-25

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

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! www.st-andrews.ac.uk/earth-scienc... ⚒️🌊🧪

The Iranian girls’ school was hit by a US tomahawk cruise missile. NPR has confirmed the footage.

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! journals.asm.org/doi/10.1128/...

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. 🌊 www.pnas.org/doi/abs/10.1...

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. Link: www.science.org/doi/10.1126/... 👏 @annaferraioli.bsky.social @maikekittelmann.bsky.social @msarscentre.bsky.social @erc.europa.eu @hfspo.bsky.social #ctenophores

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.

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 🇨🇦! 📷 Cred: Bianca Otero

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

We celebrate International Day of Women and Girls in Science as the North Cascade Climate Project expeditions have been mainly powered by women in the last decade. We are artists and scientists, mostly doing both aspects during the field season. Toughness , collaboration and joy is the net result.

Sorry for the preview pic in your feed, but we've posted a thoughtful story by @dangaristo.bsky.social that delves into the tangled web of relationships between Jeffrey Epstein and various scientists: www.nature.com/articles/d41...

Academics vying for a spot in Epstein‘s world. There are so many. I feel the need to make a thread, so I don’t keep confusing them. 1/

Well, I am in the Epstein Files ... www.justice.gov/epstein/file...

I did not expect to see a scientist proposing research in the #Epstein files that sought funding to “link sexual behavior to microbial diversity”.

We are saddened to learn of the passing of the Hon. Kirsty Duncan. A respected scientist and tireless champion of research in Canada, she leaves a lasting legacy through her leadership and advocacy, including her service as Minister of Science. Our condolences to her friends and family.

ICE executed Alex Pretti. Anything else you’re told is a lie.

So proud and happy to see my friend and fellow Earth Scientist, Marena Lin, running for congress in California. Please donate if you can! www.marenalinforcongress.com @marenalinforcongress.com

If you are curious how engaged Canada is, they are broadcasting Carney's speech in full in my local pizza shop and playing highlights in my local bank. I'm going to the grocery store next and we'll see if it's running there too lol

Really an excellent speech that offers a clear-headed analysis and way forward. Let’s hope the values and strategy it articulates actually show up in concrete policies, programs and diplomacy.

Why should scientists write op-eds? It's tempting to say the facts ought to speak for themselves. But the facts are largely whispering among themselves in the scientific literature. They need us to give them a voice. How? Advice in my latest @natchem.nature.com Thesis rdcu.be/eJlGL #chemsky 1/3

The tragedy is all of this was totally forseeable.
