The boys’ club: How Epstein’s influence shaped the exclusion of women in STEM In one email, an AI researcher suggested it’s β€œhard to be brilliant if you are worrying if you look fat or why another woman hates you.”

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?

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.

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.

Our revised manuscript is up on BioRxiv and is coming soon to an ASM journal in your neighborhood.

We show that metabolome & transcriptome profiles are frozen in desiccated Arthrobacter and that water vapor induces resuscitation.

Opinionated science Nature Chemistry - When the facts can’t speak for themselves, scientists can give them a voice, argues Michelle Francl.

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
