Interests: #Sportscience, #Metabolism, #Mitochondria #SportsNutrition but I can't resist a well-written journal article of any kind. Getting wiser now so #agingscience. Also interested in “kines” of all kinds.
I also grew up in this era. My boys did not. They grew up with video games and social media but they are empathetic, moral, kind men who are able to treat everyone—even those who are not like them—with respect. Because that’s what we taught them.
I’m Gen X. So as a kid, my summers meant getting shoved out of the house. Playing outside until dark. We swam, scraped our knees, fought, made up, and met girls. You had to make friends in the flesh. No choice.
I have a lot more to say, so check my video write-up.

My dream is a multi center study that measures maternal exposure to organophosphates and glyphosates—both of which disrupt folate metabolism, maternal folate status, the MTHFR genotype and ASD risk.
The ASD curve and Glyphosate application

The admin didn't have to do any of this. This could've been a funding announcement for a well powered multi center trial of leucovorin that considered key covariates. They could've pushed Congress behind the scenes to expand access to dietitian coverage for individuals with autism.

It’s an incredible act of cognitive dissonance. For years, the GOP has *defunded education
*voted against a livable wage
*cut healthcare to rural (all) communities
*defunded infrastructure
*defunded Medicaid
*increased anti-competitive practices
*gave incentives (Bush) to send jobs overseas

On a small level I feel for them, it's a largely thankless job, Long hours, not much money to be made, and theey are stuck in an area where the propaganda machine grinds away on then non-stop.
That said at some point you'd think something would snap and they would wake up, but they seem quite bendy

Does he realize that Americans pay for tariffs? Nope.
Soybean farmer: 60% of the soybeans we produce in this country are exported. Of that, half of those go to China. We're not gonna go back out there and find another buyer like China to replace that market share. Tariffs are gonna be pretty hard on us in agriculture

Musk has already commented about this system saying there have been “virtually no incidents”.
I’m waiting for the GOP to encode that into law wherein any company that has “virtually no incidents“ cannot be found at fault.

The worst thing about this myth is that it deflects from the real causes.
A more likely set of candidates is pesticides or any other substance that disrupts one carbon metabolism during brain development.
I would love to see parents put their energy into protesting those types of substances.

Thimerosal is a mercury-based preservative still used in some multi-dose flu vaccines.
It was falsely linked to autism in the 1990s—a myth thoroughly debunked.
This CDC page (*for now*) links to numerous, rigorous studies disproving the thimerosal/autism claim.

Your argument is absurd. First, most of the drugs for gender affirming care are generic and second, there aren’t enough children seeking gender affirming care for big pharma to spend a dime on them.
I might add that many of those scientists are receiving substantial resources from big pharma to push these medicines on kids. What do you think?

Except this isn’t what @jmroth.bsky.social was saying. He was saying that professional athletes are, by multitudes, more talented than others. Of course they have ungodly focus (sometimes) but no amount of ungodly focus is going to turn someone into a pro athlete if the don’t have ungodly talent.
No, it's not. Such kids discover the limits of their abilities somewhere along the way, or the limits of their commitment.
Pro athletes are not just "god-given" instruments; they've built and earned their level with ungodly focus and dedication. They deserve to be respected for that hard craft.

It is absolutely just talent. They may get additional training, but no amount of optimal training is going to turn someone in the 98th percentile into the 99th percentile. I cannot stress this enough. And to be a professional athlete, you need to be in the 99.97th percentile.
It ain't just talent, lots of folks have talent.
A pro player has often a decade's worth of very specialized development work already behind him/her when that first contract gets signed.
Optimal physical training, high-level instruction; their talent gets maximized + honed to a sharp edge.

Also not remotely realistic. That’s exactly what they want—for the journalist to move on or leave. The proper response is to say “I have provided you with the information, what is your response?”
Yeah, this is not remotely hard.
I’ll say it again - when *any* politician uses the ‘I haven’t read that story’ lie about something they knew they would get asked about, the interviewer has a duty to say ‘Okay, in that case I’m going to terminate this interview and you can come back when you’re better prepared.”

And another question is how Harvard would achieve the goal of dissolving diversity, equality and inclusion initiatives while simultaneously forcing them to hire professors to equally and inclusively present the “diverse” view of conservative thought.
David French’s column today says Harvard is “remarkably intolerant,” the speech environment is “abysmal,” and left-wing bias is “overwhelming.”
So I have a question: if they’re so biased against conservatives, how do they keep being a stepping stone for influential conservative lawyers and judges?
