New biology – The Obelisks.

Link. “small RNA species, hitherto unknown, that seem to be colonizing bacteria in the human oral mucosa and gut. These things are a bit like viroids, which are circular RNA species that are pathogens in plant species, but they have no sequence relationships with any known viroid.”

From a preprint. Remnants of the primeval RNA world? Able to cause disease?

“as these models get bigger and are trained on more data, they improve on individual language-related abilities and also develop new ones by combining skills in a manner that hints at understanding”

Link. “… a mathematically provable argument for how and why an LLM can develop so many abilities… when Arora and his team tested some of its predictions, they found that these models behaved almost exactly as expected”

Researchers applied techniques from random graph theory. These models have unexpected behaviors.

We don’t know if this is how *we* “understand” but I suspect it’s something similar. We are not magical.

“Many people found it a little bit eerie how much GPT-4 was better than GPT-3.5, and that happened within a year. Does that mean in another year we’ll have a similar change of that magnitude? I don’t know. Only OpenAI knows.”

2019 brain implant controls woman’s severe OCD

Link. It was done primarily for her epilepsy, she suggested doing the OCD as well. “work involved the coordination of researchers from OHSU, UCLA, Stanford University, and the University of Pennsylvania.”

Sounds like for her controlling the OCD was even more valuable than managing her epilepsy. It’s not a complete cure though.
