Genome Observatory now has a Genometrics section, where I've collated some stats about the 18k NCBI Chromosome-level genome records. Interestingly many genomes have no mitogenome, and most plant genomes have no plastid genome. Any and all suggestions for additions to Genometrics are welcomed!

🧪 New from @dataforprogress.org: Federal research grants are awarded on scientific merit judged by panels of scientists and outside experts. Trump has moved to change that. Voters don't approve. www.dataforprogress.org/blog/2026/7/...
Bar chart of polling data from Data For Progress.
Title: Voters Want Scientists, Not the President's Team, Deciding Which Research Gets Funded.
Description: When it comes to deciding which proposals for scientific research get federal funding, which of the following comes closer to your view, even if neither is exactly right?
Response Options:
A) Decisions should be made by panels of scientists and experts based on scientific merit — research funding is too important to leave to political considerations.
B) Don't know
C) Decisions should be made by the president's team — elected leaders should direct how taxpayer money is spent on research.
All likely voters — 70% chose A, 8% chose B, 22% chose C
Democrat — 83% chose A, 5% chose B, 11% chose C
Independent / Third party — 78% chose A, 10% chose B, 12% chose C
Republican — 52% chose A, 9% chose B, 39% chose C
