I truly don’t know how we undo the damage the Right has done not just to science institutions but to simply the desire to educate and be educated in this country. Many of our systems of scientific outreach are irreversibly dead and there was little pushback from the public.

Looking for BGCs in large metagenomic datasets? Our new biorxiv preprint introduces metaSMASH, a scalable fork of antiSMASH designed specifically for metagenome-scale BGC detection and analysis : www.biorxiv.org/cgi/content/... Thanks @canerbagci.bsky.social and @kblin.bsky.social ❤️

metaSMASH: Scalable Biosynthetic Gene Cluster Detection for Large Metagenomic Assemblies

antiSMASH is widely used for biosynthetic gene cluster (BGC) detection and annotation, but its standard workflow is poorly suited to large metagenomic assemblies, where massive contig counts create severe runtime bottlenecks and complicate downstream result exploration. We present metaSMASH, a re-engineered fork of antiSMASH for metagenome-scale BGC analysis. metaSMASH preserves the original antiSMASH detection and annotation logic while introducing streaming, memory-bounded execution, record-level parallelisation, optional output filtering, and an interactive dashboard for large result sets. Across 25 benchmark metagenome datasets, metaSMASH reproduced identical BGC detection results while dramatically reducing computational cost. Relative to the default antiSMASH configuration, metaSMASH was a geometric-mean 38x faster. It also outperformed an ad hoc chunked antiSMASH workflow: in the default configuration it achieved a geometric-mean 2.9x speed-up and 1.7x lower peak memory, and with extended-analysis modules enabled it was 2.7x faster and used 3.1x less memory while completing all datasets, whereas the ad hoc workflow ran out of memory on the two largest assemblies. By substantially reducing the computational burden of large-scale metagenome analysis without sacrificing result equivalence, metaSMASH makes routine mining of assembled metagenomes more practical and provides a scalable foundation for natural product discovery from complex microbial communities. ### Competing Interest Statement The authors have declared no competing interest.

Anybody knowledgeable about identifying spiders? I've snapped this one in my in-laws' garden. I'm thinking it's a Zilla Diodia orbweaver? Never seen one of those before but the abdomen markings and colouration match well with what's on the internet.

Possible Zilla Diodia orbweaver spider.

Generative AI, and LLMs in particular, seems to be causing a lot of people to lose their minds. Not in the sense of AI psychosis exactly, but a loss or abandonment of critical faculties. It’s happening everywhere, and those who are affected become unresponsive to rational argument.

If they were staging this, you all know for certain that they'd go full pro wrestling in the most inane and ludicrous possible way and have Trump single-handedly punching out half a dozen trans illegal immigrant Islamic attackers, and then defuse a bomb ...

I keep reading that AI is a F1 racecar, and the problem is that drivers aren't trained to drive it. But I'm worried about the F1 not having seatbelts, or really any safety features, we're offroading, and the wheels frequently and unpredictably come off the car. Why would I want training to do that?

Jeff Bezos has $222 billion. If he paid my wealth tax this year, we could fund insulin in America for everyone who needs it plus free school lunch for every kid in Texas—and have plenty of money left over. And Bezos would still have $215 billion dollars to spare.

Democratic senators: It's time to draw a line in the sand. A nominee for Attorney General will soon come before you. Make the confirmation process about releasing ALL of the Epstein files (without redactions) and prosecuting the Epstein class. (1/2)

saying you have nothing in common with the people in your obvious coalition is probably why you have not done a great job with organizing 😇

1. Over the last few days I have received a set of queries about my research. The first one I thought was legitimate, and I was planning to answer when the second arrived, and then the third, from the same sender. Viewed together, they’re clearly LLM generated.

i’ve come to believe that we will never solve the literacy crisis by talking about reading as “watering the garden of your mind” or whatever. books are, and have always been, the favored medium of God’s purest freaks and degenerates. Reading isn’t a salad. If you’re doing it right, it’s a vice.
