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)

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."

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.

It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the Gurdon Institute.

Executive wants to frame the NIH indirects cut as $4B in savings. But given that NIH returns $2.5 on every $1 investment, this would actually cost US economy a net $6 BILLION (per year!). Not to mention the human costs of wrecking education and research sectors and the communities they serve.

NIH directly supports the economy through investments in research institutions and job formation.

First panel, a person saying "I guess I made a transgenic". There's a doc
Second panel: A cat taking off a dog mask, saying "Guess again". The cat has EPISOMAL EXPRESSION written over it

Third panel: The person is mad and is saying "You piece of shit..."

Fourth panel: the cat giving the middle fingers. The cat has also bright green painted over it, like if they were clones of GFP
