Similar to the US data on the previous slide, data from the UK (and other countries) show this unique contrast. The (presumably, rational) humans seem to know physical activity is good for them. But they staunchly refuse to do it. Why? What does this mean for our approach to promotion?

Here @Dmozaffarian, who I like & respect, suggests a way to incorporate the new weight-loss drugs with other interventions.
But the new drugs work, and the other interventions don't. They really just don't.
I'm gonna get a little wonky here ...

I thought it would be funny to go through that depression meta-analysis by showing progressively more extended plots to get an idea of how outrageously large some of the effects were.
But instead I found a citation and coding error and I think there might be more.

Incredible advancement in text-to-video AI and the responses to OpenAI's Sora seem overwhelmingly negative. Much worrying about jobs and disinformation and how the tech should be illegal instead of demanding we all benefit with a universal AI dividend and that we finally reconfigure school to teach critical thinking, debunking, and digital literacy.
Some of us have been warning for years about how quickly this tech would advance, and the implications of that. The problem is not the tech. The problem is that we require jobs for our survival, so we need to end that with UBI.

And the other problem is that we still run school to produce workers for the 20th century instead of citizens of the 21st century. We have to teach HOW to think instead of what to think.

We need to make these changes, and when we do, we will all be better off. But until we do, the consequences of tech advancements are going to get worse.
This video was generated by Sora.
That's the new model by OpenAI. The most advanced text-to-video tool created so far.
I'll share the videos here. Absolutely insane.
Prompt: This close-up shot of a Victoria crowned pigeon showcases its striking blue plumage and red chest. Its crest is made of delicate, lacy feathers, while its eye is a striking red color. The bird’s head is tilted slightly to the side, giving the impression of it looking regal and majestic. The background is blurred, drawing attention to the bird’s striking appearance.

Results are out for the guaranteed basic income pilot in Austin where 135 people got $1,000/mo for a year.
9% of people reported working less and 7% reported working more. Of those who worked less, half upskilled for better future jobs, and half chose unpaid care work.
Housing security significantly increased, as did food security. People lived in better housing and ate more balanced meals.
People also felt significantly more connected to the people and places in their neighborhoods.

You can create the best behavioral tool for weight management, developed by AI, and it will never outperform novel obesity meds & surgery for disease management.
Why? Because the interaction between the environment and the subconscious brain predominately controls obesity.

As a neurosurgeon I've taught about the Dunning-Kruger effect.
But it isn't real.
If you think it is, this will be an eye-opener.
If you haven't heard about it before, you will still learn how false ideas can be useful and true ideas can be harmful. 🧵

Will AI soon replace nutritionists and dietitians? 🤖🥗
In a new study, researchers posed the same commonly asked nutrition questions to a group of dietitians and ChatGPT.
Answers were graded by other dietitians and subject-matter experts.
"...overall grades for ChatGPT were higher than those from the dieticians for the overall scores in five of the eight questions we received. ChatGPT also had higher grades on five occasions for scientific correctness, four for actionability, and five for comprehensibility. In contrast, none of the answers from the dieticians had a higher average score than ChatGPT..."

A mind-blowing paper has come out today in @Nature
In 2016, JC Venter Institute scientists trimmed a bacterial genome to its barest minimum required for life to synthesize what they called a "minimal genome" (science.org/doi/10.1126/scie…).
Today, a group of scientists from Indiana University reports how that minimal genome evolved over 2000 generations in comparison to the non-minimal genome.
The authors found that even when you reduce a bacterial genome to its absolute minimum where every nucleotide matters, the genome undergoes mutational events generation after generation as much as the non-minimal genome. One simply cannot stop the evolution.
Just over 300 days of evolution (equivalent to 40,000 years in humans) the minimal cell has gained everything it lacked in fitness on day one in comparison to the non-minimal cell.
When comparing the evolved traits between the minimal and non-minimal cells, the scientists found something striking. The evolutionary process increased the cell size of non-minimal cells but not that of the minimal cell. But that is not the striking part.
The scientists were able to identify the key mutation that resulted in cell size evolution. And it turned out that the mutation that helped the non-minimal cells to grow bigger is the same that helped the minimal cells to stay smaller. Growing bigger had a survival advantage for non-minimal cells and not growing bigger had a survival advantage for minimal cells. So, the mutation had a context-dependent effect. This just demonstrates that the evolutionary effects on traits have no absolute direction. All that matter is what is beneficial for the organism's survival.
The conclusion of the paper is metaphorically a quote from the Jurassic Park movie:
“Listen, if there’s one thing the history of evolution has taught us is that life will not be contained. Life breaks free. It expands to new territories, and it crashes through barriers painfully, maybe even dangerously, but . . . life finds a way". (scienmag.com/artificial-cell…)
