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. π

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.

Much of the anaerobic microbial life was not wiped out by the GOEβ¦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.

The boysβ club: How Epsteinβs influence shaped the exclusion of women in STEM
In one email, an AI researcher suggested itβs βhard to be brilliant if you are worrying if you look fat or why another woman hates you.β
The trove of files released by the Department of Justice, illuminates Epsteinβs 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)

A pilot in a submersible vehicle collecting sediments samples in 30 meters of water looking for Asgards (microbial relatives of eukaryotes)
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

Epstein files reveal deeper ties to scientists than previously known
Latest batch of documents show researchers consulting the financier and sex offender on publications, visas and more.
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...

A photo of a large TV on the wall of a pizza shop. It's displaying Canadian prime minister Mark Carney speaking at the world economic forum.
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
