UVA Study Reveals How New Weight-Loss Drugs Reshape the...

Their study is intriguing. In short, what they found was that the weight loss drugs affect your brain chemistry so that not only do you “feel full,” but you also don’t crave certain food types.

You might say it’s a side effect that wasn’t completely intentional, but is useful in a way.

And that got me to thinking… back when Covid was the talk of the day, a vaccine was introduced that had been developed and tested for quite some time. It helped the body’s immune response, so that it could fight off the infection. It did this by working with the response at the RNA level.  
But people got stupid, and listened to their crazy uncle or some “influencer” who told them that it affected their DNA (different three letter acronym, but also in the body) and would change them somehow.  And that this vaccine was never tested and on and on.  They rejected the science and accepted wild conspiracy theories. 

And yet, when GLP-1s were introduced, they were never tested for use in weight loss but people used them that way because like magic they were able to shed pounds.  And here we are.  It wasn’t tested thoroughly for this purpose, and it does, in fact, change one’s brain function.

But it’s perfectly okay! It’s recommended by these same influencers and crazy uncles because it helps fight off obesity.

I think “the jury is still out” on these drugs, and their long-term effects. And yeah, they apparently do work as weight loss drugs.  And the side effect related to cravings may be an okay thing.

I’m just fascinated (maybe alarmed) by how science is eschewed, until something has a seemingly desirable effect on how one changes behaviors and loses weight. 

Updating Darwin: Biologists are returning to an older theory to explain anomalies in evolution

This is an interesting thought experiment about how Lamarcks theories on inherited traits turn out to be true, but not quite in the way that he suggested.  Rather, it’s a more nuanced thing that happens in evolution. 

So the suggestion that both he and Darwin are both correct in their evolutionary theory, and can be used together to explain how plants and animals

The explanation is helpful, but the embedded video showing how one can easily calculate the weight of the earth using some weights is very, very cool
