  • Masks don’t just inhibit the spread of Covid. They caused a precipitous drop in influenza, another potentially deadly disease, during the height of the pandemic. And other respiratory diseases were diminished as well. People with compromised immune systems were ironically safer in public places than any other time in their lives. Now these spaces which continue masking provide social interaction and emotional support for them and their friends. I didn’t know it was a thing but I think it’s great, I hope they make enough business to continue. I mask when I’m in indoor public places because my vulnerable spouse is recovering from their second pneumonia hospitalization this year, but I’m aware masks are better at containing germs than keeping them out, which is why the group effort is more effective.











  • It’s not unique to humans at all. They originally found the two types of brain cells by looking at mouse embryos. Then,

    "Finally, the researchers looked back over 550 million years of evolutionary time. They found the same two-origin brain pattern in chickens; zebrafish; and, remarkably, in acorn worms, tiny creatures living on the ocean floor that share a distant common ancestor with humans. Jellyfish, which diverged from humans about 600 to 700 million years ago, have two nervous systems at different ends of their body.

    “Our research suggests that evolution took two existing neural systems and pushed them together spatially,” Loh said. “Having the brain as one organ would probably be more efficient, but we rely on this primordial way to make the brain as two separate pieces.”

    We’ve long known the forebrain, midbrain and hindbrain control different things, we just didn’t know the hindbrain neuron cells evolved so fundamentally differently. Being able to grow the right kind in a lab will enable research that wasn’t possible before.
