Hypothesis: tissue/cell types with the least somatic mutations have the highest regenerative potential. There is a selective pressure to prevent differentiated tissues from regenerating, as to not propagate deleterious somatic mutations.

Today's the last day to apply for the Plant Cell Assistant Features Editor (AFE) program, usually postdocs or senior PhD students! It's a fantastic opportunity, a great learning experience & a lot of fun too.
If you aren't quite ready, in June 2026 Plant Physiology will open its own call for AFEs 👍

No shade on Ambros and Ruvkun, who did amazing work on the first miRNA. But Hamilton and Baulcombe were the ones that showed these are a whole class of molecules.

Out of curiosity I just tried ChatGPT plagiarism checker. It falsely accused the text I checked of copying "verbatim" from citations that do not include the text it quotes. When I point this out, ChatGPT admits it was wrong. Totally useless and worse, potentially harmful.

Rather than framing it as “universities have become dependent on federal funding”, it should be framed as the US depends on universities for innovation & training.
much has been said about the NYT's framing of the growth of the government-university research complex as a story of higher ed "dependency" on government

How Universities Became So Dependent on the Federal Government
For decades, universities got billions in federal dollars for research. The relationship was mutually beneficial, until President Trump decided it wasn’t.

I remember when I was doing rice pollen small RNA for my PhD work, I kept getting sRNA that are ~30-ish. We thought these were due to bad RNA integrity, so we gave up working on it. Didn't know these half tRNAs are actually important.

I received a heartbreaking email today: A paper in a special issue I’m editing is being retracted because one of its authors is afraid of losing their job and their legal status in the U.S. if they publish a scientific study on evolution. Yes, on evolution, nature's engine of diversity.

1. Grow ecoli overnight 37C in LB shaking 250rpm
2. Spin down 1mL 15sec 10,000xg
3. Decant and resuspend in 500uL of ice cold TSS buffer. Vortex to resuspend in 3 pulses 1 sec.

For technology papers, one way to tell if the authors actually want others to use their new techniques (rather than just a PR paper): if they have deposited their plasmids or plasmid sequences (if applicable) anywhere.
