Lithium-free sodium batteries exit the lab and enter US production (newatlas.com)

Sodium-ion tech has received heightened interest in recent years as a more reliable, potentially cheaper energy storage medium. While its energy density lags behind lithium-ion, advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative, especially for stationary uses like data center and EV charger backup storage.

This is going to be interesting to watch over the next few years and decades. Battery technology is having a moment, for obvious reasons, and the Midwest stands to benefit if interest in sodium-ion technology continues to grow. There's a giant salt mine in Cleveland that extends beneath Lake Erie and another under Detroit.

Evaluation of ChatGPT’s responses to information needs and information seeking of dementia patients - Scientific Reports (nature.com)

[L]arge language models such as ChatGPT can serve as valuable sources of information for informal caregivers, although they may not fully meet the needs of formal caregivers who seek specialized (clinical) answers. Nevertheless, even in its current state, ChatGPT was able to provide responses to some of the clinical questions related to dementia that were asked.

I suspect this is true for medical information on the web, too — good for most of us, incomplete for medical folks.
