As habitual AI user for writing who regularly sees "100% human" scores on text with 80%+ LLM-written words, I suspect that: (i) reliability of AI detection is overestimated, (ii) writing of latest-gen models is under-appreciated, and (iii) "LLM-generated" is not as clear cut as many people think

Poster session: where “I’ll just have a quick look” somehow turns into a 20-minute scientific deep dive 😄🧪 Yesterday’s poster session at 'Chemical biology' had all the right ingredients: a little chemistry, a little biology, and a lot of interaction ⚗️💬 #EMBOChemBio @embl.org @embo.org

What regulates the urge to sleep? William Joo and colleagues identified brain regions that reflect how long mice have been awake. Strikingly, inhibiting one of these regions reduces sleep by 70%, without the major behavioral deficits associated with sleep deprivation. www.nature.com/articles/s41...
