Knowledge is NOT politically neutral. The scientific method is a tool for deriving knowledge. So why then, are we telling the arbiters of the scientific method and developers of knowledge to be politically neutral? Are scientists supposed to forsake knowledge for politics sake?

Everyone say it with me: AI companies are ✨extraction machines at scale✨. They are DESIGNED to sift through a million stupid ideas per second to find the next golden egg they can monetize. And they are destroying our Earth, at scale, to do this.

The person who thinks that he has the ability to decide which science to fund out of hundreds of subfields is exactly the person who should not make that decision. There is a reason that expert committees of scientists review and give recommendations for funding. No one person can know all of it.

Unpopular journal suggestion: Journals which are primarily online should take a plain text document with limited HTML and some way to treat equations as text and allow me to change the font class (serif/sans serif); background/text color; font size and font spacing to make reading easier.

That's not most people, obviously, but it's also not that rare. To put that in perspective: people who are neither XX nor XY are more common than people with Multiple Sclerosis. Roughly as common as people with Down syndrome, or people with Parkinson's disease.

It doesn’t matter if you eat organic foods. It doesn’t matter if you exercise regularly. It doesn’t matter if you inject peptides. It doesn’t matter if you have “good genes”. None of these things will prevent you from contracting vaccine-preventable diseases. There is only one thing that will.

1. So, at the Worldcon this year there was a person who was going from panel to panel, bothering panelists by trying to get them to "collaborate" with them on a project and sliding the proposed project to them on a piece of paper. Folks, I cannot stress to you how obnoxious this sort of thing is.

I am very serious about citing resources (ZFIN, Flybase, Wormbase, yeast, mouse, rat, human, etc) and asking authors to cite them precisely for this reason: the more we talk about them and cite them in our papers, the better chance we have at justifying why we should increase the budget 🧪

My hot take is there shouldn’t be science influencers. Science is too vast & complicated to have *one person* be an expert on everything. The trap of being The Smart One is a poison. The best science communicators understand the limits of their expertise and defer to others to fill in the gaps.

4. The figure in a paper is not the figure to show in a talk. In a published article, figures can be really complicated and detailed, because people can sit with them for a long time. You might even get away with that in a poster. You can't in a talk. Simplify.
