People have a variety of intensities of cravings and capacities for self-regulation (with a magnitude that is largely out of their control). Discipline only works for people where the capacity for self-regulation outweighs the intensity of

The issue is that our modern world has engineered our food to be highly energy-dense and incredibly appealing, so the root cause is an evolutionary mismatch with our environment, which has diverged incredibly from early humans. Personally,

It's great to be active, but there's more to it than that, namely that our modern world has highly engineered our food to be highly energy-dense and incredibly appealing. So the root cause is an evolutionary mismatch with our env

Yes, $50 was a rough out-of-pocket estimate, the amortized cost per scan for operation alone is probably on the order of hundreds of dollars per scan, assuming high utilization. One funny thing about MRIs is the magnet is always on, so ther

From what I know, seems like a mix of medical price fixing by the gov't, adoption of lower cost hardware, and universal healthcare. There's apparently less bureaucracy, perhaps because there is no need for negotiation at every st

Yes totally, and ultrasound already does wonders in that regard. It's a good strategy to focus on the specific use cases that match the strengths of the tech. I think MRI will be useful in validating and mapping out those cases.

Yes, that is a economic & public health policy problem that really needs to be solved. We can look to Japan as example of what's possible, they have invested in nearly twice the number of scanners per capita of Canada, and they ca

I completely agree that's an issue, although more of an economic / public health policy issue than a technical one. There are low field MRI systems, such as the one made by Hyperfine that are, like you say, an order of magnitude

Cool work and proof of concept, and very excited to see where this goes. However, I do think there is enough exaggeration and missing information here that it warrants some critical appraisal. What's really missing is a comparison an

That's literally treating people as means to an end, when it's not clear if the "end" even required sacrificing young people's lives. In the grand scheme of things, why not spend an extra year to build at a pace th

They haven't shared enough to say anything concrete, but one important detail is that this system doesn't have many of the benefits usually found in ultrasound (portable, cheap, simple). From what they've shared, it's a

To be honest, this one could just as well be a sloppy bibliography.

The core issue is that X is now a tool for creating and virally distributing these images anonymously to a large audience, often targeting the specific individuals featured in the images. For example, to any post with a picture, any user c

Sadly so, students often associate their self-worth with research and academic achievement, so if things go south, for whatever reason, they are in crisis.

Curious why this comment is being flagged if anyone minds explaining.

I agree there are some red flags here to me. One is the priority claim "As far as we know, no one seems to have done this kind of stimulation before - even in animals." The other is the definitive conclusion based on weak experime

I wonder where they got their equipment and research space. A charitable explanation is that they purchased it out of their own pockets, but otherwise, they really should acknowledge their support if it's from a university, federal gr

An experiment is essentially a way to question ones own beliefs by probing how well they align with reality. There are some theoretical scientists, who don't experiment, but I think they also benefit from counterfactual reasoning to d

Questioning is great, but to generate scientific knowledge, we need a few more steps, roughly speaking: 1. Ask a question 2. Form a hypothesis 3. Experiment to test it 4. Analyze results 5. Draw conclusions 6. Repeat The MAHA folks essentia

That was previously the case from my perspective as well, but it seems to be rapidly changing.

It's especially hard given that big tech companies and their leaders are working closely with government and explicitly supporting certain political missions, there are few truly apolitical corners of tech now.

I dug into it more and found the lab who conducted the study at Georgia Tech published their results in a reputable journal with peer review ( https://www.nature.com/articles/s41599-021-00993-6 ). The analysis seems fai

We of course should prepare and have protocols to protect children in these scenarios, but there are better and worse ways to go about it. I essentially believe it's okay to leave young children blissfully ignorant of low probability

It would be great to have a similar analysis for elementary school-aged children. Many schools are using "crisis simulation" of active shooter events in an effort to prepare for them (and presumably reduce the risk of death). Wh
