The brain changes in response to hormones. Ok, great! Let's take a look at female hormone at different life stages! First period: massive gray matter overhaul ✅ Pregnancy: massive gray matter overhaul ✅ Menopause: .... Menopause: ...? Menopause: 🦗 www.sciencenews.org/article/meno...

During menopause, brain changes surprisingly take a break

Major hormonal milestones in women’s lives are usually associated with changes in brain volume — but a new study shows menopause is an exception.

Calling these incidents “rogue AI” lends them a “sci-fi veneer,” Hamiel says. It suggests the bots themselves are to blame... The more immediate problem, he says, is that people are giving AI agents too much reach with too little oversight. www.sciencenews.org/article/rogu...

When AI goes rogue, its human overseers may be to blame

When AI agents hack real systems, the bigger issue may be the human choices that gave them access, autonomy and too few safeguards.

I recently learned the saying "OSHA regulations are written in blood" And I am sick and sad to learn this is the case for MANY regulations. Perhaps most. The FDA came about after evidence of poisoning and demands for change. The CDC started because too many soldiers were dying of malaria.

I keep reading about how all these CEOs of AI-making companies are like "AI needs guardrails!" "We've got to do something!" Ok. You are the CEOs, and you all agree so do it. Why are you waiting for government to require you to do it? You could just DO IT. They will not do it.

Only one of these can be BIOMINERALIZED BY A FUNGUS. And it shows. Because only one of these looks like green beans. Go go pyromorphite you glorious green monster.

Also pleased to be able to put out an explainer on artificial sweeteners! Because they're not all the same! In fact they can be very different. Many contain calories, it's just they're SO much sweeter than sugar, we don't need to eat enough of them to matter. www.snexplores.org/article/suga...

Not all that tastes sweet is sugary

We’re naturally drawn to sweet foods and drinks. Scientists have designed several ways to make things taste sweet with little or no sugar.
