1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.

LLMs hallucinating nonexistent software packages with plausible names leads to a new malware vulnerability: "slopsquatting."
LLMs can't stop making up software dependencies and sabotaging everything

Studies of fecal bacteria have led some researchers to propose a link between the gut microbiome and autism.
But a new paper argues the claim rests on shaky foundations. https://scim.ag/48lckEh

Research linking gut microbes to autism is deeply flawed, critics say
Amid growing investment in the field, a new paper argues it rests on shaky foundations

One of CDC’s final blows. And what it means for you.
Where to find trusted health information now?

For a very particular reason, ALAN DERSHOWITZ, I’m thinking about how the Harvard Law Faculty, which Dersh is a member of, were VERY vocal about how Harvard’s mee Obama-era title IX standards were too stringent and “unfair” to accused perpetrators
To be very clear, Virginia Giuffre was made to say she mistakenly identified Alan Dershowitz as one of the people who sexually abused her. Here is the proof from this week's Epstein files dropped by the House Oversight Committee.

A question that comes up a lot in my consulting work is, "What are the most important data management practices a team can get started early, that will lead to better quality data?"
In this new blog post I write about some of the core practices to implement. 👇

Clinical Researchers:
I am here to warn you about a meteor hurling towards us.
That meteor represents increasing scrutiny of clinical research; and in particular how we approach data collection, analysis, interpretation and reporting.
Prepare now, or face the consequences.

happy mole day (as in Avogadro's constant, 6.022 x 10^23)!
in undergrad I loved competing in my chemistry dept's "Mole day" contests. this is from the year my Holy Moly priest and altar server lost to another student's Moley Cyrus on a wrecking ball. 😆👩🔬
