human brain cells in rats

You wouldn’t necessarily get the idea from this Nature article that it is about implanting human brain cells in rats. But according to this (sensationalized?) article in Axios, that is exactly what it is about. The scientists are doing this to study diseases like autism that they can’t just study by growing human brain cells in a jar (which they have been doing for some time, apparently!).

Given all that, this is the paragraph that really caught my eye:

A current concern, though, is whether organoids might be transplanted to non-human primates. Paşca says there is no need: “It’s not something that we would do or that I would encourage doing.”

So it could be done then. And what can be done, Somebody somewhere will probably eventually do.

I have a childhood memory of seeing the Rats of Nimh on the big screen and being utterly terrified. By the Rats. Who were supposed to be the good guys in the story.

December 2021 in Review

Most frightening and/or depressing story: Mass migration driven by climate change-triggered disasters could be the emerging big issue for 2022 and beyond. Geopolitical instability is a likely result, not to mention enormous human suffering.

Most hopeful story: Covid-19 seems to be “disappearing” in Japan, or at least was before the Omicron wave. Maybe lessons could be learned. It seems possible that East Asian people have at least some genetic defenses over what other ethnic groups have, but I would put my money on tight border screening and an excellent public health care system. Okay, now I’m starting to feel a bit depressed again, sitting here in the U.S. where we can’t have these nice things thanks to our ignorant politicians.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: Time reminded us of all the industries Elon Musk has disrupted so far: human-controlled, internal-combustion-fueled automobiles; spaceflight; infrastructure construction (I don’t know that he has really achieved any paradigm shifts here, but not for lack of trying), “artificial intelligence, neurotechnology, payment systems and cryptocurrency.” I’m not sure I follow a couple of these, but I think they missed satellites.
