New comment by mallomarmeasle in "Ants: Who looks after the injured in a colony?"

That is super cool. Unfortunately I cannot access the original article to see the methodology, but they mention using a system that can track individual ants in a colony of ~100.

I wonder what kind of biometrics allow that. The ants do not seem to be tagged individually in the linked video: https://www.uni-wuerzburg.de/fileadmin/uniwue/2026/0702Ameis...

Not to be too speciesist, but the ants kind of all look the same to me.

Thanks, I was trying to recall that article. Fascinating stuff to this non-expert.

Interesting story. The lack of dramatization might have something to do with making Nazis sympathetic characters. Hogans Heroes aside.

Poor Billie’s snoot! Glad you are such a caring owner.

Please consider the nickname “Tycho Brahe” for her.

Thanks for that, super interesting about sieches. A standing wave not directly from the moon or waves.From the wiki:

Lake seiches can occur very quickly: on July 13, 1995, a large seiche on Lake Superior caused the water level to fall and then rise again by one metre (three feet) within fifteen minutes, leaving some boats hanging from the docks on their mooring lines when the water retreated

As pointed out above me, 250-300 micrograms is what you likely meant. You might have to hunt for such low doses. I split a 1 mg tab in quarters. Repeated studies have shown that there is not an increase in efficacy, but there is an increase in adverse effects when doses are higher.

I think the style is intended to evoke the way the story developed at the time, as drips of new information came in on the news. I stuck with it and am happy with that decision.

New comment by mallomarmeasle in "Is Ketamine Neurotoxic?"

mallomarmeasle — Mon, 24 Feb 2025 13:41:49 +0000

For anyone interested in the therapeutic (or otherwise) use of ketamine, I strongly recommend the autobiography of John Lilly, the neuroscientist who developed the sensory deprivation tank. His discussion of ketamine-aided spiritual entity discovery and dolphin communication are enlightening.

New comment by mallomarmeasle in "Mirror bacteria research poses significant risks, scientists warn"

Besides the achiral glycerol mentioned in the article, some bacteria subsist on methane. That is also non-chiral and in large quantity in petroleum and under the sea.

Yes. Some bacteria have D-amino acids (such as D-alanine) as part of their cell walls (which otherwise contain almost entirely L-amino acids). D-amino acids are also sometimes incorporated into drugs that are synthetic peptide mimics in order to slow metabolism.

They say in the article that capillary action draws the coffee along the narrow edge. This is aided by surface tension, just like how water is drawn into a capillary tube.

Doctor-chemist here. You are correct. The carbon-fluorine bond is very inert to metabolism. Ingested Teflon would be almost entirely eliminated unchanged.

Takes pretty harsh conditions to break Teflon, but interestingly it can react with explosive violence, as I have witnessed, when combined with small particle sized Mg.

Besides the well-known opioid peptides, such as the endorphins, the opiate morphine itself is endogenously produced in humans as a signaling molecule. This was a controversial and highly surprising finding to many in the neurosciences.

This demonstrates that placebo analgesia is actually activating the opioidergic pathway.
