AI Keeps Failing at Microbiome Prediction Why simple models keep winning, where deep learning still shines, and where the field is headed

AI has huge promise for genomics -- but it has consistently failed at microbiome-based prediction.

My new post on why simple models keep winning, where deep learning actually earns its place, and where the field is headed

I fucking hate proline so fucking much it's the worst amino acid it's so fucking stupid it's incapable of being fucking normal so it forms an ugly ass ring with itself with its own fucking nitrogen cuz it's a loser fucking amino acid I hate it so much I'd rather cut off my right tit than have to ever draw a mechanism with proline ever again

Remember that everyone you meet is fighting their own battle, sometimes with amino acids

In case you missed it: our review titled "Spatial structure: shaping the ecology and evolution of microbial communities" is out! 🚨

Let me hit you with some highlights on why spatial structure matters. (and why you should care!)

Sharing is appreciated πŸ™ πŸ§΅πŸ‘‡

Phage-microbe interactions may contribute to the population structure and dynamics of hydrothermal vent symbionts Abstract. Deep-sea hydrothermal vent ecosystems are sustained by chemoautotrophic bacteria that symbiotically provide organic matter to their animal hosts

Excited to share that @michelle-hauer.bsky.social's paper with @katiekliermicrobe.bsky.social @maggielangwig.bsky.social @karthik-a.bsky.social on phage interactions with chemosynthetic symbionts was published today. #NSF and @schmidtocean.bsky.social supported. academic.oup.com/ismecommun/a...

Love this new paper from @tjvmajors.bsky.social and colleagues - looking at contributions of chemosynthetic contributions to net primary productivity with a focus on interesting winter dynamics! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

There is no hierarchy, I repeat, there is no hierarchy.

No animal alive today is β€˜primitive’ – why are so many still labeled that way? All species alive today, from chimpanzees to bacteria, are cousins that each have equally long lineages, rather than ancestors or descendants of one another.

The idea that humans sit atop an evolutionary hierarchy dates back to 1866, when a scientist drew the first tree of life with "Man" at the top. This inaccurate view still shapes how we think of the animal world, despite decades of genomic evidence proving evolution has no hierarchy.

Oxygen metabolism in descendants of the archaeal-eukaryotic ancestor - Nature Sequencing of marine sediments finds 136 newly identified Heimdallarchaeia and several novel lineages, and indicates that Heimdallarchaeia evolved distinct metabolic capabilities from otherΒ Asgardarchaeota, in conditions that may have given rise to early eukaryotes.

Alright friends, I've been tasked with making Women in Science stickers for an event and I'm trying to expand both the racial and national diversity of the women who appear. So drop me your favorite women in science (loosely defined here) and, if possible, a symbol you'd use to exemplify their work

We don't have to choose between the economy and the planet.
The UN reports that nature-based solutions (restoring forests, sustainable agriculture) can provide 37% of the climate mitigation needed by 2030.
Investing in green jobs isn't charity,it’s the most intelligent long-term investment.
