Some still do: it's called a gastrovascular cavity, and is present in marine invertebrates such as Cnidaria (jellyfish, coral polyps, anemones), Ctenophores (comb jellies); Platyhe…

Yes, oral exams, content created in plain sight, project-based activities, all of these can provide a true appraisal of student understanding. But these approaches, although highly…

After retiring at 65 from a university teaching and research science career (all pre-AI), I went back to teaching, but this time teaching high school science, mostly AP STEM course…

I was born in Beantown and remember the site before construction (“Scollay Square”) as being pretty seedy and a place to avoid (still least for an eight year old). The new City Hal…

This can't be said often enough. We have two right wing parties in the US. That's it.

Great link, thank you.

> Quite sure that is the schools job. At least where I live the schools tend to assume several of the rights and responsibilities that normally fall on the parents. Yes. The school…

> KDE connect is my goto for sharing between phone and computer. Ditto. KDE connect is flawless, one of the best features.

My experience is that Word (and Office products in general) have worsened over decades, favoring and indulging the least adroit user to maximize their user base, cloying the produc…

Really glad to see this work and result. My PhD dissertation 25 years ago (pub cited in group's Science paper) focused on laboratory synthesis of dolomite at lower temperatures (le…

Thanks for an excellent product. I'm a long term paid subscriber, and very happy with Bitwarden :-)

Great, uplifting story, thanks for including it.

The chemical composition of the world ocean reflects the balance of inputs from the continents (as described, from riverine input as well groundwater), atmospheric cycling, and out…

I couldn't bear to use Windows without `Everything`. It's the only way to reliably find _anything_.

“I'd buy that for a dollar!”

I bought and installed a Sommer Evo+ (German made), after Chamberlain, Craftsman products crapped out prematurely. So far, so good (7 years), extremely quiet; slow, but well put to…

I'm glad you got a good one. I didn't (Zenfone 5z), and after their customer ‘service’, have sworn off ASUS for good. https://www.reddit.com/r/zenfone/comments/ollaq6/i_will_neve..…

Great book, well ahead of its time.

Or, “Well, think me up a cup of coffee and a chocolate doughnut with some of those little sprinkles on top ...”

Inspired! Still grinning, thank you.

I drove a cab in Boston in the 70's (yes, I'm probably older than most here). The work was hard, tedious, dangerous, and uneven in terms of income: some nights you'd make out ok, o…

I agree (academic research scientist, geosciences, now semi-retired). The current system is utterly unsustainable. Many outside academia are unaware how much universities rely on f…

David Graeber has argued persuasively that there is little real anthropological evidence to support the notion that money arose from the ‘inefficiency of barter’. [1—3] 1. https://…
