There are political prisoners in the UK on hunger strike, some who are now very ill. This has got very little media coverage. Good to see some coverage, now there needs to be some action.

When I was a medical student 45 years ago, I clerked in a 13 year old girl with deep jaundice and an abdominal mass. She was Hepatitis B positive. That had led to a primary liver tumour. In a 13-year-old. She was dead within the month. Avoidable with vaccination.

The CDC has endorsed ACIP’s decision of revoking universal access in USA to hepatitis B vaccines at birth. The policy had been in place for 34y and was changed despite no new evidence emerging of any risk of vaccination. #HealthPolicy 🧵
CDC accepts ACIP’s hepatitis B vaccine recommendations for babies
The CDC also said if a baby is not receiving a birth dose of vaccine, the initial dose should be administered no earlier than 2 months of age.

Such a cool study. Makes me wonder if there is more salt accumulation in the central Congo peatlands which may explain why there are such high densities of elephants and gorillas there.

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.

Dispensing false information in a confident tone, rather than offering no answer when none is readily available, is a major flaw of generative AI, experts say. An audit of the top 10 generative AI models including ChatGPT, Gemini and Meta’s AI by the media literacy non-profit NewsGuard revealed that the non-response rates of chatbots went down from 31% in August 2024 to 0% in August 2025. At the same time, the chatbots’ likelihood of repeating false information almost doubled from 18% to 35%, NewsGuard found. None of the companies responded to NewsGuard’s request for a comment at the time.

Indigenous protected areas have much lower deforestation rates than other areas, so lowering emissions from deforestation (second largest cause climate change after fossil fuel emissions).

Huge applause and long standing ovation for Marina Silva, what a life, from rubber tapper in the Amazon to environment minister, and quiet star of COP30. Even though the roadmap to halt deforestation is voluntary, if led by Silva, it will be positive.
