The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes: 🖌️ Dozens more images with duplications or painting 🖨️ Hundreds of blots that all share the same background (behold slideshow below)

Don't be shy to take on a little two-week side project. These five months will be the most precious three years of your academic journey.

We don’t have the fish but we have the plasmid, and find that since it’s a secreted factor anyway you can pretty much just inject every time and the mosaicism doesn’t matter

Scientist's way of saying 'I ❤️ you' "I found this paper/preprint that made me think of your project." "I checked the mice/cells/plates already." "I just sent you the edits you requested." "I have a slide/diagram that will work for that." "I had that problem with [lab equipment], I have a fix."

As a someone with a 33 year NIH-funded lab whose grant is supposed to be reviewed this week, shut NIH down if that is what's needed to end ICE terrorism. Innocent lives are more important 🧪

He was a consummate gentleman and scientist. The ways he treated people, loved science, and ran his lab are all things I’ve always tried to emulate. He had an outsize impact on me and so many others, and he will be sorely missed.

Sam Wattrus @samwattrus.bsky.social · 08/10/2025
He entrusted me with resources and space to try things, ask for help, fail, and succeed on my own. He had tea with us every day and chatted freely about life and science. He always kept doing benchwork – his office had a microscope, incubator, and injection rig so he could do his own experiments.

Even as an inexperienced student, John treated me - and everyone in his lab - as a colleague. When I showed up on my first day, John was the one who met me at the front door to let me in and show me around the institute which bore his own last name.

Sam Wattrus @samwattrus.bsky.social · 08/10/2025
When I was an undergraduate just starting lab work, I (somewhat naively) cold emailed John asking if I could work in his lab for the summer. Even though I was just a random student from the US that really had barely any experience to speak of then, John agreed to take me on.

So incredibly sad to learn of John Gurdon’s passing. It is hard to overstate what a big deal he is to developmental biology - a legend. Leaving aside his phenomenal scientific achievements, I want to take a moment to highlight how he was also an exceptionally kind person and incredible role model.

We are hiring! The Wattrus lab at MGH is seeking talented postdoc applicants to join our group and study differences in regeneration and wound healing across species using fish models. We are a fun group - come and join us! Fishy friends, please spread the word! #zebrafish #medaka #zebrafishjobs
