Microbes that have the greatest genomic potential for secondary metabolism tend to be multicellular. Here, we show that signatures of ancestral BGC expansions within 3 bacterial phyla and 2 fungal lineages coincide with origins of complex multicellularity [1/12] 🧵 www.nature.com/articles/s41...

While the situation is grim at NIH, it's closer to catastrophic at NSF. They're just not able to move any money out the door. It appears OMB has them on lockdown. www.science.org/content/arti....
Figure showing NSF funding curve in 2026 compared to prior years.  The line is nearly at zero as of mid February.  As Science and Nature have reported, NIH and NSF have made only a relative handful of new grants since their 2026 appropriations became law, partly because of the OMB delays. A new rumor among the U.S. academic community is that, even after OMB signs off, it will hold agencies to the levels Trump requested for them in May 2025 rather than the more generous amounts Congress approved. For NSF, which received an appropriation of $8.8 billion, a version of those rumors holds that OMB must approve any spending above the president’s request of $3.9 billion—and that any additional outlays must clearly align with the administration’s priorities.

⚒️🧪 Even more sobering to me is that by removing the nodules, which take millions of years to form, the very slow ecosystem recovery will be to a very different state than what was there before. A signal of our thoughtlessness that could last until the ocean floor itself is subducted.

Studies only making reads available may satisfy journal requirements but do not serve the larger community. If you work with any form of metagenomics/genomics data, and are for open access and FAIR data policies...Please consider making ALL your data public (genomes, proteins, reads, metadata).

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.
Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.
