Removing race from kidney function algorithm helped more Black patients access transplants Removing race from the eGFR had a big impact, resulting in 5.3 more kidney transplants per 1000 Black candidates.

A long-used medical test underestimated the severity of kidney disease in Black patients. New study says with the bias removed, transplant rates are up. www.statnews.com/2026/03/10/k...

The "ChatGPT Health Will Kill You" Study LLMs can't triage, for the millionth time.

Don't trust ChatGPT Health – or likely any general health LLM – to give you medical advice in the context of a serious acute illness. Patient triage is clearly outside its functional requirements.

Paediatricians’ blood used to make new treatments for RSV and colds Antibodies harvested from the blood of paediatricians are up to 25 times better at protecting against the common respiratory infection RSV than existing antibody therapies, and are now being developed...

Pediatricians are cool to begin with

Now their blood is being used to make new treatments for RSV and colds! 👏🏽👏🏽

This is fantastic, and it's something that we've been saying for years.

When companies say that are using "AI for climate change", they are referring to much smaller models used for doing things like climate modeling.

Massive generative AI models are NOT USEFUL for mitigating climate change.

The One Metric That Could Reshape Health Progress Tracking the percentage of people dying before old age provides an honest accounting of a population's health.

The percentage of people dying before age 70 is an honest accounting of whether our health systems are working. For the United States, that number tells us we’re failing nearly one in four people.

The US recorded 160 new measles cases in the past week, 44 fewer cases than recorded the week prior, but still more than any week in 2025. The US has recorded 902 total cases in 2026, after 2,128 cases recorded in 2025.

oooh we are posting super bowls?

As a specialist in Islamic ceramics *cracks knuckles* I present this fabulous 11th c. lustre painted bowl from Fatimid Cairo depicting a Coptic priest. Its white glaze imitates Chinese porcelain and the lustre technique was invented in Iraq a century earlier.

The largest randomized trial of medical A.I.
—Over 100,000 women in Sweden
—radiologist + AI vs 2 radiologists, in follow-up
—AI added led to 29% more cancer detected, 44% reduced workload, and
—Less cancer dx in subsequent 2 years, and, when found, less aggressive

Feels like this was going to happen sooner or later. A dairy cow in the Netherlands tests positive for antibodies to #H5N1 #birdflu, which has infected many, many, many cows in the U.S.
