Any recommendations for books / vids for little ones interested to learn about microbiology?

My 5yo has picked up on work chatter and keeps asking β€œTell me about Klebsiella?” and I am running out of ideas! πŸ˜‚

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

rambaut/figtree Automatically exported from code.google.com/p/figtree - rambaut/figtree

The first version of FigTree was released nearly 20 years ago and it is still widely used (including by me). But there are currently 85 issues on the GitHub repo (github.com/rambaut/figt...) and some of them I don’t really like the look of.

Statement from Dario Amodei on our discussions with the Department of War A statement from our CEO on national security uses of AI

When even the AI company CEOs say β€œwhat you want is unethical and a bad idea”, it’s time to sit the fuck down and have a serious think about what you wanted.

Make no mistake this is a concerted and organised attempt to completely undermine science and expert opinion. This is Covid denialism on steroids and it’s on all of academia to see this for what it is and push back as strongly as possible

The fundamental premise behind AI-enabled cheating is that coursework is merely busy work, because your'e just doing it for professors.

We would never say that showing up for football practice is merely busy work because you're just doing it for your coaches.

Except literally every data analysis or model I've ever asked AI to build has contained at least one error: www.nature.com/articles/d41...

Common response: "But someone just needs to give AI detailed instructions..."

But who is the "someone" in that sentence? And how did they get their expertise?

Before the vaccine, 10% of measles infections resulted in deafness. Measles currently causes 100K children/yr to become blind. Even those who recover completely can later develop the fatal encephalitis. Every infection disrupts the immune system and can cause loss of all immunity to other infections
