🧪 Can researchers stop AI from fabricating citations? Probably not entirely. While models like GPT-5 are improving, hallucination is fundamental to their statistical design, shifting the burden onto users to build new intuitions for an AI age. #MLSky #AcademicSky

*** Ontario Variant Update (to: Aug. 16, 2025) *** Ontario COVID sequence updates have been more frequent over the past month with the XFG.* "Stratus" family of variants now at 74% of sequences, NB.1.8.1.* "Nimbus" at 22% and LP.8.1.* down to 3%. #Variants #COVID #XFG #Stratus 🧪🧵1/

A fascinating new preprint w/one very unexpected finding suggests, I believe, that a large proportion of Long Covid may be due to chronic infection in a particular bodily niche, which could be crucial for finding effective LC treatments. It requires some explaining. 🧵 1/33

Understanding Canadian Air Quality Health Index (AQHI) & Wildfire Smoke Wildfire smoke consists of toxic gases and particulate matter (PM) when breathed in gets into our lungs, bloodstream, and even our brain. 🧪🧵1/ #IAQ #IndoorAirQuality #wildfire #smoke #AQI #AQHI #Canada

Here is your chance to provide constructive feedback on the proposed updated Canadian Standards Association (CSA) respirator standard which calls for universal respirator use in healthcare settings & when performing patient care outside of healthcare settings (eg – in the home).

How you can help: The draft CSA Z94.4 Standard is now out for Public Review until August 19, 2025. Please weigh in with your positive, constructive comments at publicreview.csa.ca/Home/View/22... . Public Review comments are open to everyone who registers.

Good News! Canadian Standards Association (CSA) has called for universal respirator use in healthcare settings & when performing patient care outside of healthcare settings (eg – in the home) in the latest edition of CSA Z94.4, Selection, use and care of filtering respirators.

Interesting comparison of different PM sensors outside the lab. Great customer service to replace with a better functioning model.
