🌊 25 years of Argo and ocean observation records! ▸ 50,000 km: the longest journey ▸ 6,000 m: the greatest depth reached ▸ 16 years: the longest operational lifetime ▸ 3 years: the longest continuous mission beneath sea ice Challenge: can you guess which float achieved each records?!

New study by Alexander Henoch (@ahenoch.bsky.social), a PhD student in our group @hifmb.de and @awi.de, shows what it takes to bring gene synteny into microbial pangenomes, and what we learn about the variability landscape of genomes when we do that. See the pre-print here: doi.org/10.64898/202...

The NSF GRFP is now out! There are 2,599 awardees, which is the most ever—and a big shift from last year which initially halved awardees (1,000 awardees + an additional 500). I've thrown together a plot to break down the changes by field. www.research.gov/grfp/Awardee...
Plot showing GRFP awards by directorate shows a big dip last year and major increases for engineering and biology (though this only brings it back to parity with 2024).

Kudos to the @seattletimes.com for spelling with diacritical marks used in the Hawaiian language, the ʻokina and the kahakō. A few years ago, when I asked the NY Times to spell my affiliation as University of Hawaiʻi at Mānoa, they refused because it went against their style guide.
