There are two recent papers that use sourmash in creative ways - and it gladdens my heart! pubmed.ncbi.nlm.nih.gov/40812187/ by @silask.bsky.social et al looks cleverly at human gut subspecies. www.biorxiv.org/content/10.1... by @rayanchikhi.bsky.social et al counts billions of k-mers. Super neat!

Another super cool bioinformatics tool (this one using pyani and sourmash) - genomeRxiv, for exploring multiscale taxonomic relationships between genomes. From @borisvinatzer.bsky.social group, by Reza Mazloom, and also with Lenny Heath - all at VT.

For whatever reason, the US government have decided the US should no longer lead in science. Great economic opening for other countries, but really bad for America. This could be stopped by a handful of majority senators. That they aren't doing it tells you they want us to cede 70 years of building

As we start the new year, I would like to remind everyone that it is now almost 120 years since the US decided consumer protection - by which I mean regulation - mattered. Given the upcoming presidential inauguration, let's talk about how that happened - and why it's so important. (A thread)

Regularly tempted to write in my NIH grants innovation section: "Funding software that already exists and works well would be highly innovative for the NIH." (I bet half the panel would break down ROFL, but I'm also highly skeptical that I'd get a good score, or that the PO would be amused.)

40% of the mass of everything transported by a ship in 2023 was a fossil fuel. That stat paired with this new study shines a pretty harsh spotlight on how obscenely bad-faith the right-wing concern trolling around offshore wind + whales is www.seattletimes.com/seattle-news...

New research shows that the top threat to whales around the globe has changed. But it wouldn't take much to reduce the risk, researchers say.

This is a very important idea, and worthwhile for those developing bioinformatics software to consider. One massive shortcoming, over which the scientists & devs have quite little control, however, is the huge dearth in funding software dev & maintenance. Software is its own product & requires $!

It's important to realize how long scientists have warned those in power. Climate change is not somebody's fault for not recycling beer cans. It's the result of a fraud against the public by corporations who have flooded the zone with bribes and misinformation.
