“Aware of my inability to detect AI use with certainty, I implored the students: please don’t use AI. It’s terrible for you. It’s terrible for me, a dystopian experience of spending weeks giving detailed constructive feedback to a machine.” www.forkingpaths.co/p/the-death-...

The Death of the Student Essay—and the Future of Cognition

One professor's reflections on the end of an era, as AI tools such as ChatGPT have murdered the student essay (RIP). Here's why that threatens the future of human cognition—and how to save ourselves.

Finals start tomorrow here at UIUC. You may have seen the NYMag article outlining how pervasive AI has become in student course work, how it's degrading the learning experience. I wrestled with it all semester in my own course. But OpenAI knows the effects, and they known exactly what they are doing

Happy to see our latest work out in G3 @genetics-gsa.bsky.social. This is the fourth notothenioid genome our group has assembled so far -- a highly cold-specialized fish with a large complement of antifreeze proteins and an interesting set of chromosomal fusions/rearrangements.

Our paper on the genome assembly and annotation of the Antarctic bald notothen (Trematomus borchgrevinki) is now available in G3! This paper was lead by @niraj-rayamajhi.bsky.social, in collaboration with Bushra Fazal Minhas, Chris Cheng, and @jcatchen.bsky.social. doi.org/10.1093/g3jo... 1/n

New preprint up! We sequenced hundreds of samples from across one of Earth's oldest living organisms - the Pando aspen clone - to understand how mutations accumulate and spread in long-lived clonal organisms. Our results were…surprising. 1/30

If you are interested in the recent attempts to regulate Apple in Europe with the DMA, this is a really interesting (and long) piece by Steven Sinofsky, a major software engineer at Microsoft during its antitrust days (and after). hardcoresoftware.learningbyshipping.com/p/215-buildi...

If you have a sequence that you love – a gene family, transposable element, regulatory feature – you probably spend a lot of time looking for it in different sets of sequence. If so, you might find our latest preprint and software tool, Klumpy, useful. www.biorxiv.org/content/10.1...

Interesting paper from J Pritchard's lab: "GWAS variants differ from eQTL variants along many axes…GWAS hits are biased toward more constrained genes…with complex regulatory landscapes…eQTLs show strong promoter bias largely absent from GWAS hits"
