@elduvelle_neuro @BlakeP_Neuro
Apologies for the late reply, I haven't logged in for a long time. Yes, this does sound like what we reported. Happy to share analyses and/or chat. Feel free to email me.

“I visited the Port of Izmail today and was shocked to see the level of destruction left by the Russian strikes on grain storage facilities on 2 August. The thousands of tons of grains that were damaged would have been enough to feed approximately 66 million people for a day.” - #UN humanitarian coordinator for #Ukraine Denise Brown.

@matti I don't see that as a likely outcome. Those who don't want to review simply turn down the review invite anyway. There is no need for them to get univited to review.

@matti We all suffer this way. There is a simple solution:
1 All papers are on biorxiv and all reviews are anonymous but pulbished, even if paper is not accepted.
2 People can vote if a review is bad (-5) or very good (+5).
3 Referees with very bad score are pruned by the editors (who know the referee ID).

Problem solved!

The Hyperloop was never meant to be built. Elon Musk admitted it was all about fueling opposition to California’s high-speed rail project so it would get canceled.

He never planned to improve transportation; he just wants to keep people trapped in cars.

The most egregious false solution may be the Hyperloop. The modern version of the concept was proposed by Musk a decade ago as a pure hypothetical. Musk, a noted public transit hater, saw it as a way to reduce support for California’s planned high-speed rail line between Los Angeles and San Francisco. “It seemed that Musk had dished out the Hyperloop proposal just to make the public and legislators rethink the high-speed train,” reporter Ashlee Vance wrote in his 2015 biography of Musk. “He didn’t actually intend to build the thing.” Musk’s ultimate hope? “High-speed rail would be canceled,” explained Vance.

Brenda Milner did a lot more pioneering work than you'd guess (see article). Remarkably, most of it is still useful after 60+ years! She will be 105 on July 15. Award committees, now is your chance to recognize her pioneering work and send her a great birthday gift.

Imagine a free, informal block party. Then, a bully walks in, injects himself in all conversations, spreads misinformation, fires people and asks for a monthly $8 fee. That's what M#$k did and gained a whopping 100million+ followers within a year.

Do you support this?

Speaking at conferences increases citations by 52%!
nature.com/articles/d41586-023

But
-In person meeting requires airline travel, fuels greenhouse gases.
-Less wealthy can't afford to travel or get visas. Referees prefer papers from known/famous authors. In person conferences create a vicious cycle.
-"I invite you, you invite me" enables nepotism.
-A handful of famous voices dominate the airwaves.
-This stifles the young investigators and disruptive innovation.

What's the solution?

@tao
This is an important point. Related, LLM errors should not be called hallucinations, they are *confabulations*.

Accurate diagnosis is the first step towards a cure.

(Hallucination: the act of seeming to see or hear somebody/something that is not really there, especially because of illness or drugs.
Confabulation: a patient generates a false memory without the intention of deceit.)

The #NationalAcademies of Science, Engineering, and Medicine is hosting a virtual workshop on the topic of "AI to assist mathematical reasoning": nationalacademies.org/event/06 , to be held June 12-14. (I am one of the members of the organising committee). Registration for the workshop is now open, and the schedule of speakers and panelists is now available. We plan to follow up on this workshop with an in person event later this year.

There is nothing you do voluntarily that has this level of risk. Not flying, not skydiving, not driving.

We do nothing special to 'sell it'. Just upload the same preprint to biorxiv, that we send for publication.

Here is one preprint that did analysis of existing data to find new results: Megascale movie fields all across the mouse brain, from LGN to CA1!

I am sorry & surprised that you can't post theory paper on biorxiv. We have posted many computational preprints without any problems and their policy allows this:

BioRxiv is intended for rapid sharing of new research results, defined as experimental, mathematical, or computational work.

Following Elsevier's decision to raise the article processing charge for NeuroImage to $3,450, all editors (inc. chief editors) from NeuroImage and NeuroImage:Reports have resigned, effective immediately.

I am joining this action and have also resigned.

@MatteoCarandini @bc_butler

This is quite the graph, from your thread: annual profit at Elsevier in 2020 larger than annual HHMI grants and Wellcome Trust grants. So much research left on the table, swallowed up by RELX shareholders and Elsevier's fat cats' salaries and R&D to extend its tentacles beyond being a mere publisher. What a missed opportunity.
