After a quite medical talk on human cell lines I was attending, somebody was asking the question: What is the relevance for C. elegans?

🧵🚨: Remember the recent #genAI cheating scandal at Brown? Everyone talks about the average score drop from take-home midterm to proctored final: 95.7 → 48.8. That number alone can't settle anything. But the released data can, and almost nobody has looked at it. So we did! Read on. #AcademicSky

What exam scores can and cannot prove about unauthorized AI assistance: Evidence from a highly public classroom episode

In spring 2026, an economics professor at Brown University gave a take-home midterm and, after unusually high scores, made the final exam proctored. Among the 59 students who completed the course, ave...

A new retraction for an influential evolutionary biologist is raising the question of whether scientific misconduct more than 20 years ago was just a blip in his impressive publication record or further proof, as some claim, that much of his work rests on a shaky foundation.

A prolific evolutionary biologist caught faking data decades ago notches a new retraction

A study claiming a tenfold decrease in bugs splattered on evolutionary biologist Anders Møller’s windshield over two decades has been retracted. shanecotee / iStock Anders Møller, an influential ev…

EMBO Reports@emboreports.org · 4mo ago

Philipp Rieche, Marten Exterkate, Arnold Driessen et al show that the #lipid divide between #bacteria and #archaea is not as strict as previously thought as bacterial lipid synthesizing enzymes can use both stereo-forms of glycerol-phosphate. #MembraneBiology -> link.springer.com/article/10.1...

Bacterial lipid synthesizing enzymes PlsY and PlsC utilize both stereo-forms of glycerol-phosphate - EMBO Reports

The chemical composition of membrane lipids differs between eukarya, bacteria and archaea. The central dogma posits that the stereochemistry of phospholipids in bacteria is distinct from archaea. Bact...

Today marks 30 years since we identified the apicoplast, a relict plastid in human and animal parasites (PMID 8632819). Apicoplasts are the target of the widely used antimalarial prophylactic doxycycline, which has saved many thousands of malaria infections.
