The effect of cannabis use on the time course of positive and negative affect in the daily life of youth
Excited to share our newest publication. Here we test a central hypothesis in cannabis use, does use alter a person's emotions in a theoretically expected way, and if so for whom and under what conditions is that observable. We found that cannabis use was linked to complex changes in emotions.

OpenAI admits AI hallucinations are mathematically inevitable, not just engineering flaws

OpenAI βacknowledged in its own research that LLMs will always produce hallucinations due to fundamental mathematical constraints that cannot be solved through better engineering, marking a significant admission from one of the AI industryβs leading companies.β

Congress Is Reversing Trumpβs Steep Budget Cuts to Science

A 'Super Flu' Is Spiking in the U.S. β and Hitting Kids the Hardest
Multiple states have reported child flu deaths in recent days, as cases and hospitalizations rise sharply across the country.
So as RFK ends annual flu vaccine recommendations for children, hospitalizations and deaths among children are rapidly accelerating--with prior data showing that nearly all the mortality is among those not vaccinated.

Children will die with RFK Jr.'s new vaccine recommendations. We're NOT doing the "experts disagree" game. The US vaccine schedule was painstakingly constructed through a deep & thorough process by experts with unquestionable expertise. This is policy by fiat. It is pre-meditated murder. 1/

βBe kind, be involved, believe in your art,β he said. βAt a time when people tell you art is not important, that is always the prelude to fascism. When they tell you it doesnβt matter, when they tell you a fucking app can do art you say, if itβs that important, why the fuck do they want it so bad? The answer is because they think they can debase everything that makes us a little better, a little more human. And that, in my book, and in my life, includes monsters.β

My Open Letter To That Open Letter About AI In Writing And Publishing
The tl;dr before you get into this post is this: the SFWA came out, said that some AI usage was okay enough in books for the authors of those books to not to be disqualified from winning a Nebula aβ¦
Apparently I'm doing this -- my open letter to that open latter about AI in writing and publishing. I emerged from Hibernation Week to write it, so god only knows how much sense it makes. But at least a human wrote it, so that's nice.
Bonus: picture of my "cat," sweet baby Boomba.

I see the promise of AI here, the doors it could unlock.
But is AI the magic key? Or is it the key that's been determined most likely to work based on other keys someone saw once?
To say it without a tortured metaphor: I'm skeptical that AI can translate without putting its own stink on things.

I am in awe of anyone writing in a language other than their first. If tomorrow every major scientific journal started publishing in German, I would have to quit.
Your English may be imperfect, but I am in awe of it.
So I don't know exactly how I feel about all this. Depressed, mostly.

Despite what my colleague said, though, I don't think it's really a time issue.
I think a lot of it is a confidence issue. And I get it.

Why? My colleague offered two reasons:
1. Time. It takes a long time to write a review in a second language
2. To not sound super critical and hurt Americans' feelings π (we love to dance around our words, Germans are direct)

Putting aside the hyperbole (sigh, can you even have AI without hyperbole?), I'm not surprised by the numbers.
Last month, I complained to my German co-author that a review we received seemed AI written. Their response: "Most of us non-native speakers do that now."
