What is alive? what is dead?

Before multicellularity, cooperation, etc, there are the thermodynamic constraints.

The Open at CMU team at Carnegie Mellon University Libraries supports researchers in making their work more transparent, accessible, and reproducible by providing expertise in open science, open data, open access publishing, and open-source software.

A national study put out by our incredible team of librarians is shedding light on how libraries are keeping up with the fast-changing world of #OpenScience. The study appears last month in The Journal of Academic Librarianship.

The method also identifies non-rich nodes which are crucial for information flows btw rich nodes.

Plus? It has a clear statistical interpretation.

Teeth first evolved as sensory tissue in the armored exoskeletons of ancient fish, fossil scans find Anyone who has ever squirmed through a dental cleaning can tell you how sensitive teeth can be. This sensitivity gives important feedback about temperature, pressure—and yes, pain—as we bite and chew ...

New paper from the lab: Our teeth arose as sensory organs on the outside of the body of ancient jawless fish.!! Congrats to Yara Haridy and the team!

Using LLMs as "Approximate Information Synthesizers" has been the best approach I've found.
