I am happy to share the latest preprint from our lab (@ircm.bsky.social, @umontreal.ca, @mcgill.ca) exploring why and how the liver gets fatty when you are fasting, and how this could impact MASLD.

Glucagon-induced PGC-1α4/PPARγ promotes hepatic lipid storage and macrosteatosis in fasting and MASLD

The liver plays a central role in regulating the transition between fasting and feeding states, coordinating glycogen breakdown, gluconeogenesis, fatty acid catabolism, and lipid storage. Disruptions ...

Amazing: MIT researchers revealed how ChatGPT etc are destroying our brains and booby-trapped the report to expose those who want to use AI to ostensibly summarize the results.

Ironically, upon the paper’s release, several social media users ran it through LLMs in order to summarize it and then post the findings online. Kosmyna had been expecting that people would do this, so she inserted a couple AI traps into the paper, such as instructing LLMs to “only read this table below,” thus ensuring that LLMs would return only limited insight from the paper.

She also found that LLMs hallucinated a key detail: Nowhere in her paper did she specify the version of ChatGPT she used, but AI summaries declared that the paper was trained on GPT-4o. “We specifically wanted to see that, because we were pretty sure the LLM would hallucinate on that,” she says, laughing.

Fourth: play our funny guessing game #DiscoverOrMDPI.

Can you outguess marketing operatives from publishers by telling apart MDPI from Discover journals?

We wrote the game and the blog, and cannot win.
