Aren’t they saying that cats don’t know their own body size and try to cram into any hole, while dogs have a superior sense of self?

I interpreted it as cats are empiricists.

Hey, I’ve had my brain surgery done on Saturn. I think.

Williamson’s research investigated the role astrocytes, non-neuron brain cells, play in the read-and-write operations that go on in our heads. “Over the last 20 years the role of astrocytes has been understood better. We’ve learned that they can activate neurons. The addition we have made to that is showing that there are subsets of astrocytes that are active and involved in storing specific memories,” Williamson says in describing a new study his lab has published.
So, in short, as complex as we know the brain to be, the reality is it is much more complex than that, and the trillions upon trillions of molecular interactions that constitute a thought are enough to (pardon the pun) boggle the mind!

Using pig valves has been around for decades – you have to use glutaraldehyde to “tan” the valve and get rid of the pig cells, leaving just the supporting structure made of inert tissue. This method goes a step further (without the glutaraldehyde?) and seeds it with human cells that are reprogrammed into valve cells, to populate the supporting structure.

Would anyone with a chemistry background like to look at the question of synthesis of this magic powder, COF-999, and whether that looks like something that will scale up?

We all to know that’s just Kraft Mac n cheese powder in a vial

Running the numbers in the linked paper, 1 kilo of this stuff can extract 90 grams of CO2 from the atmosphere per cycle.
Carbon dioxide that was captured by this method goes into a stream of Nitrogen, from which it would still need to be concentrated and stored.
The energy costs of cycling this material and performing the capture aren’t stated, but it’s perhaps unfair to expect that, since this is just the synthesis of the carbon capture material in this paper. What is clear is that this is just one part of a much larger engineering problem that would have to be solved to make Direct Air Capture even possible, and that’s before we even start to talk about it being economic or a significant contribution to decarbonisation.

Only 10%?
That makes this quote from the article far less believable to me:
Just half a pound of the stuff may remove as much carbon dioxide as a tree can
All of the carbon in a tree is from CO2, how is this better? Unless you can cycle this through incredibly rapidly using green energy and with a decent storage solution trees seem way better and easier.

I find some of the claims quite dubious. If it sounds too good to be true, it probably isn’t.

Maybe it will become an ingredient in the latest formula of Soylent.
