Contest models highlight inherent inefficiencies of scientific funding competitions Scientists waste substantial time writing grant proposals, potentially squandering much of the scientific value of funding programs. This Meta-Research Article shows that, unfortunately, grant-proposa...

Far from the whole story but we wrote about the grant proposal contest component a few years ago. Thinking about other elements of your question this summer….

LLMs are nothing more than models of the distribution of the word forms in their training data, with weights modified by post-training to produce somewhat different distributions. Unless your use case requires a model of a distribution of word forms in text, indeed, they suck and aren't useful.

CBS News entered a new period of turmoil on Tuesday after the executive producer of
"60 Minutes," Bill Owens, said that he would resign from the long-running Sunday news program because he had lost his journalistic independence.
In an extraordinary declaration, Mr. Owens
β€” only the third person to run the program in its 57-year history - told his staff in a memo that "over the past months, it has become clear that I would not be allowed to run the show as I have always run it, to make independent decisions based on what was right for '60 Minutes, right for the audience."
"So, having defended this show - and what we stand for - from every angle, over time with everything I could, I am stepping aside so the show can move forward," he wrote in the memo, which was obtained by The New York Times.

This is the right thing to do, and it’s a profound shame that he had to do it. www.nytimes.com/2025/04/22/b...

State Terror A brief guide for Americans

"the president defied a Supreme Court ruling to return a man mistakenly sent to a gulag... and spoke of sending Americans to foreign concentration camps.
This is the beginning of an American policy of state terror, and it has to be identified as such to be stopped"

Replacing Federal Workers with Chatbots Would Be a Dystopian Nightmare The Trump administration sees an AI-driven federal workforce as more efficient. Instead, with chatbots unable to carry out critical tasks, it would be a diabolical mess

In this Op-ed for Scientific American, Asmelash Teka Hadgu and I discuss one of the many reasons the idea of replacing US federal workers with so-called generative AI systems should terrify us. 🧡

1/4. On the White House’s theory, if they abduct you, get you on a helicopter, get to international waters, shoot you in the head, and drop your corpse into the ocean, that is legal, because it is the conduct of foreign affairs.

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.

(1/3) It needs repeating: in 1994, Ukraine was persuaded to give up its nuclear weapons to Russia in return for the US, the UK, and Russia guaranteeing Ukraine’s sovereignty, security, and territorial integrity.
