This is a great and thoughtful thread on the issue of why students are disengaged. I agree- covid made it worse and so did AI not those are not the reasons. I think it's attention spans w cell phones plus *struggling* being removed as an essential student skill starting with pre-K.

We need to correct the wide-spread omission of equal contribution in article indexing Equal contribution designations (co-first and co-last authorship) is on the rise, yet this information is routinely lost, creating inequity in recognition and crediting. This Perspective calls for…

Are you the less lucky of the co-first or co-last authors? @shougroup.bsky.social makes the case for changes to the way that equal contribution information is sent to indexing sites such as #PubMed.

Could the #ribosome be a selfish element? @mkrupovic.bsky.social & Eugene Koonin propose that the #evolution of life can viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources.

One of the best pieces of editing advice, ever, comes from Spooky Grandpa: your new draft is your old draft minus 10% of the word count.

It's hard, but it really does transform things

Unfalsifiable by Design: A Year of Trying and Failing to Reproduce a Human Microbiome and Autism Study The myth of open data, reproducibility, responsibility, and accountability in science, and your role in it

How every layer of science's "self-correcting machinery" failed when Iva Veseli and I simply wanted to reproduce the findings of a high-profile study on gut microbiome and autism:

Let me know a song you listen to that you think is perfect.

What I mean is: the lyrics and melody, sure, but also the performance, the arrangement, literally everything about the recording. Like, even if you could you wouldn't have the artist(s) change a thing.

and no more spoilers! Check it out to see how we found that RhoGAP15B locally suppresses RhoA-Myosin at the front of the cluster, creating a relaxed zone that promotes protrusive activity, letting leader cells move forward while the cluster stays coordinated.

Median survival went from 6 months to 13 months. It may not sound like much, but for metastatic pancreatic cancer, this is big, IMO. We finally have something solid to build on in this field.

I highly recommend that everyone follow artists. If you do, your feed is filled with art every day. Real, original art. It's bonkers that you can even have this. Amazing. Undeniably cool.

And then support those artists, when you can, because that helps the delight continue.

Scientists invented a fake disease. AI told people it was real Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

Bloody hell. Researchers invented a disease, published two fake papers to see if LLM’s would ingest them and kick them up as fact — and then it broke containment and all the major AI’s bought in. Information pollution.
