"How can funders avoid crossing the Szilard point?"
The Szilard point is "the threshold at which the total cost of competing for a grant equals (or surpasses) the value of the available funding."
The Szilard point is "the threshold at which the total cost of competing for a grant equals (or surpasses) the value of the available funding."
Point of no returns: researchers are crossing a threshold in the fight for funding
With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

Check out this cool story from @alexdemendoza.bsky.social lab about the deep evolutionary origins of transcription-linked 6mA in eukaryotes. Glad to have been involved in it.
Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9
Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics
Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.

Convergent genome evolution shaped the emergence of terrestrial animals - Nature
Comparisons of 154 genomes from 21 animal phyla and outgroups have been used to reconstruct ancestral adaptation to life on land across 11 distinct terrestrialization events, revealing strong evidence for convergent genomic evolution across the animal kingdom and recurring periods of terrestrial colonization.
