Newly released Stockholm Declaration recommends the following reforms to publishing:
1. Academia resumes control of publishing
2. Incentive systems to merit quality, not quantity
3. Independent fraud detection and prevention
4. Legislation and policies to protect science quality and integrity

Reformation of science publishing: the Stockholm Declaration | Royal Society Open Science
Science relies on integrity and trustworthiness. But scientists under career pressure
are lured to purchase fake publications from ‘paper mills’ that use AI-generated data,
text and image fabrication....

The current environment is making it near impossible to run clinical trials in the UK.
One key issue discussed in @brain1878.bsky.social
is the duplication - or worse - of regulatory oversight at NHS hospitals & universities.

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

Ever wondered how basketball players know when their throws are in/out?
L. Brun & @perrineporte.bsky.social asked players to rate confidence in their throws under variable visual feedback.
Turns out vision helps adjust confidence in successful, but not failed throws:
