I used 99%. 70% will probably work too. I can test later and let you know.

- Comment on BlackRock is Suing UnitedHealth for Giving “Too Much Care” to Patients After the CEO was Murdered 1 week ago:
As far as I can tell, this is the legal document associated with the lawsuit: …courtlistener.com/…/gov.uscourts.nysd.642027.1.0…
The most significant component of this claim is not the lawsuit itself (examples of frivolous lawsuits are common), but that BlackRock is the one suing. BlackRock doing this is the important and remarkable claim here.
I see no obvious connection between Roberto Faller and BlackRock. To me this looks like a frivolous lawsuit issued by a random inconsequential individual. So, then, framing it as BlackRock suing is blatant misinformation.
I could be missing something here, perhaps there is indeed a BlackRock connection that I was unable to identify. But that Medium article is certainly not explaining the connection. The CBS article does not mention BlackRock.
If there is no connection to BlackRock, then adding “BlackRock” to the title is not click-bait! It is a blatant lie.

- Comment on I probably interact with people who are at the pinnacle of their chosen skill but I'd never know because that skill isn't something that generates fame. 1 week ago:
I think that for mid-levels of fame you can find a mixture of musical skill and self-marketing/entrepreneurship.
But as you go up the ladder of fame you get to the rungs where money is used to pay for an artist’s exposure. The artist becomes an investor’s asset and the “skill” of building fame arguably belongs to the investors / management team. And it is not so much skill as much as it is the power of capital to purchase attention.

Awesome, thanks! I will look into it.

You are welcome! Wanted to do this for some time and writing about it is a way to force myself to think about what I see more carefully.

That is very cool! I did not know they were producing in Switzerland. I would like to visit. Do you know if they routinely open to the public?
I wonder if the “magic sauce” is a polyimide. Those polymers are often used as the dielectric layer to make capacitors that are humidity-sensitive. These polymers have sites into which water molecules can reversibly dock such that the occupancy at equilibrium is proportional to the % relative humidity.
- Comment on The Inside of Sensirion's SCD4x 4 weeks ago:
That is true. To me, the sensor data in itself is of value because I am interested in learning about, for example, whether the CO2 emission changes while the fruiting happens. But it is definitely not necessary for achieving good results. I see it more like a hobby on top of a hobby. Hobby stacking!
- Comment on The Inside of Sensirion's SCD4x 4 weeks ago:
The CO2 has not proven too valuable because the humidity controller refreshes the air before CO2 builds up. But the humidity sensor is quite handy. I made a simple humidifier and it gets triggered by a raspberry pi over Zigbee when the humidity drops below 85%.
- Comment on The Inside of Sensirion's SCD4x 4 weeks ago:
Probably not! That was a mistake on my part. The better term would be photoacoustic sensing I believe, so I have edited the post to use that term instead.
Although the response is proportional to the absorbance value at a narrow wavelength range, and CO2 is detected selectively because its molar absorption coefficient is high at that specific wavelength. I think the argument can be made that this is an action spectroscopy method limited to a single point. But I am not quite sure, so ‘photoacoustic sensing’ wins. Thanks!

I’m happy to share and glad someone else finds it interesting too :D
I also use SHT41 for other projects. It is a very nice sensor. I made an incubator with PID control and tested multiple different sensors, and the SHT41 was my final choice. Responds very fast and its accuracy is excellent.
In my mushroom chamber I have found out that CO2 is not actually an important control variable because the humidity is what changes the fastest and blowing humid air through the chamber brings the CO2 down anyway. So I would probably be able to get away with the SHT41, but measuring CO2 is just fun.

Looking through the archived history of the talk page, I can confirm that the claim on the wiki page is derived from the viral post, and not the other way around: en.wikipedia.org/wiki/…/Archive_3#Chalchiuhtlicue…
- Comment on Chat, is this true? 2 months ago:
How did I miss that?!
My timeline is incorrect then. Since the post from sassymetischick.bsky predates the wiki edit, it is more likely that the wiki edit was made in response to this meme, and not the other way around. This pretty invalidates what I said above…
I still can’t find any evidence of this being an actual trend, but I no longer have a good guess about the origin.

Yes, but that version is in German. That website also has one in English: annas-archive.org/slow_download/…/0
Let’s see…
Woah, interesting. The author is José López Portillo. I thought he shared the name with a former Mexican president, but, nope, the author is a former Mexican president.
The title of the English version is a bit different, but the text appears to be the same. It is a novel, and I can find no mention of the gulf of Mexico or of Chalchiuhtlicueyecatl in this book. To me it looks like a mistake in the citation.
The claim appears to come from this text (citation 1): scribd.com/…/Dioses-prehispanicos-de-Mexico-mitos…
Unfortunately, that book does not contain references nor is it stated where this claim comes from.

Hah, sure, let’s investigate 🕵️♂️
The term ‘Chalchiuhtlicueyecatl’ was added as a potential Aztec name to the English wikipedia page on February 15, 2025, by user ‘Mxn’.
The description of the edit is the following:
Frum says the Aztecs had no specific name for the gulf, which is plausible in a practical sense, but Fernández gives a specific religious name and is more of a reliable source on this topic
So, it is clear that the term was identified by user Mxn by performing an active online search.
If we investigate a bit further, we can see that the term Chalchiuhtlicueyecatl is described to be a name for the ‘Gulf of Mexico’ in the spanish Wikipedia: es.wikipedia.org/wiki/Chalchiuhtlicueyecatl
This page was updated to include the description of Chalchiuhtlicueyecatl as the ‘Gulf of Mexico’ in September 16, 2018. I don’t have access to the citation so I don’t know if the citation specifies if this term is still known/used.
If you check the history you will find that the same ‘Mxn’ fixed a typo in this page on February 15, 2025.
So, from this sequence of events it is highly likely that the term ‘Chalchiuhtlicueyecatl’ was included into the Gulf of Mexico wiki page as a result of the user Mxn performing an active search for Aztec names for the Gulf of Mexico.
I can find no evidence of native people referring to the gulf of Mexico as ‘Chalchiuhtlicueyecatl’. I can find no mention of this becoming viral in Mexico.
I find it highly unlikely that:
- User Mxn added an obscure Aztec term to the Wiki page two weeks ago AND
- This same obscure Aztec term coincidentally began being used by Mexican natives, and this trend became popular enough to be noticed by foreign media but not by Mexican media
More likely…
- Mxn actively looked for a term and updated the English wiki
- Someone read the English wiki, thought this would be a nice story, made the meme
And this concludes my little investigation 🧐
- Comment on Cellular Consciousness: Life Does Not End With the Death of the Body. 3 months ago:
Always exciting to learn about new perspectives on consciousness!
I have searched for the “Cellular Basis of Consciousness (CBC)” theory and I do not personally find it very compelling. I appreciate that the hard problem of consciousness is very difficult to address using the scientific method, but I suspect that consciousness arises from a form of processing that requires computations of the kind performed by animal brains. I don’t think that the kind of biophysics that allows cells to sense and respond to the environment are enough to create a conscious experience.
About the: “third state”. Cells are alive, independently of the multi-cellular organism that they come from. I don’t agree that changing the way that the cells are organized constitutes some “third state”.
Despite my disagreements, it is still nice to read and think about. Thanks for sharing.

Hello!
Yes, the !biology@mander.xyz community is a community for general biology-related content.
There are also more specific communities that focus in more specialized topics, such as such as !palaeontology@mander.xyz.
If you have an interest in a specific topic, feel free to create a community that reflects that interest. Some instances are very general while others try to limit communities to those that fit a range of topics, so it is best to create a community in an instance for which the topic is in scope.
