We find that the dominance of additive and pairwise interactions on community function may not reflect biological simplicity, but fundamental limits of statistical detection.

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

Surveyed misconceptions around #AntibioticResistance are fascinating:

• 66% believe they aren't at risk of resistance when taking antibiotics
• ~70% assume ‘antibiotic resistance’ refers to the body gaining resistance
• ~25% expect antibiotics for viral infections

Can you trust the results from gut microbiome tests? Maybe not Seven firms reported inconsistent results on the same sample, some over multiple tests. These gut microbe discrepancies could have health consequences.

Very happy to see Wasm gaining traction as a low barrier to entry alternative for programming thanks to the massive efforts by @quantstack.bsky.social 🎉 We're collecting Wasm resources for bioinformatics and beyond at wasmodic.github.io

@wytamma.bsky.social 's WASM tools have transformed my experience of teaching Python to first year undergraduate biologists this year. Since last year, I've been teaching ~400 undergrads how to code (functions, lists, dictionaries, loops) over (one hour intro lecture +) two 2-hour practicals. 1/n

Host Pathogen Interactions during Catheter-Associated Urinary Tract Infections As a leading cause of healthcare-associated infections, catheter-associated urinary tract infections (CAUTIs) present a unique challenge due to the high prevalence of multidrug-resistant and polymicrobial pathogens. Distinct from uncomplicated UTIs, the insertion of a urinary catheter provokes tissue damage that triggers inflammation, plasma extravasation, and the deposition of host fibrinogen. This inflammatory response drives the robust recruitment of immune cells and plasma extravasation, leading to the accumulation of fibrinogen─a key coagulation protein─on the device and bladder epithelium. This fibrinogen-rich environment creates a unique niche for intricate host–pathogen interactions. Crucially, uropathogens exploit these deposits to establish persistent biofilms, while the protein scaffold simultaneously modulates host immunity. Understanding these mechanisms, particularly the role of fibrinogen-binding adhesins, is vital for developing targeted, antimicrobial-sparing therapeutics. In this perspective, we examine the strategies uropathogens employ to persist in the catheterized bladder, the corresponding host immune response, and emerging strategies to prevent CAUTI.

Ever wonder what really goes down in the microscopic battleground of a catheter-associated UTI? 🦠⚔️ Our new review unpacks the Host-Pathogen Interactions during CAUTIs. Thank you, Kurt Kohler and Alyssa La Bella @alabella14.bsky.social for putting this together!!! pubs.acs.org/doi/full/10....

VWR ULT freezer panel

Does anyone have this -80 freezer and/or have the manual and/or know how to turn it on and set the temperature?

Does it go through an automatic burn in period before setting temp?

(Never mind the cracking panel…that was from me breaking it open)

Tilivalline (produced by some K. oxytoca complex strains) has been proposed as an alternative to the chemotherapy drug paclitaxel (aneugen, so indirect genotoxin that causes cell cycle arrest). Would be interesting to see how TV acts in combination with antibiotics.

This is kinda how I've felt too. The students are saying they didn't get what they paid for which is 100% true without in any way being a critique of staff efforts or a suggestion we shld have ignored law + importantly, it's DRIVEN BY A PREDATORY LAW FIRM who are the actual villans, not the students
