What will population immunity to SARS-CoV-2 look like in a post-vaccine world?
An updated outlook (2025)

Five years of COVID taught us one thing: immunology didn’t fail, our public discourse did. My new Substack cuts through the noise with evidence, not ideology. If you want facts over fear, and science over spin, join here:

Welke is nu de leugen dan? In 2024 geeft Eva Munnik openlijk toe dat ze zich selectief niet hield aan bepaalde (door haar als onzinnig beoordeelde) maatregelen, vooral de QR-code, terwijl ze in 2026 claimt zich wel aan de regels te hebben gehouden. 🤷♂️ Alles voor een boek?

It is not finished. Human body temperature appears to be declining across generations. New work suggests neural circuits can directly regulate thermogenesis and fat tissue.
Perhaps obesity is not only about calories in, but also about calories out.

Infighting is typical on the political left. Purity of principle is often prioritised over the practical issue of winning elections. Votes may now be split and lost to what is needed most: to hold a terrible president to account. Republicans will certainly not perform this critical role.

A mutant mouse led to the discovery of leptin. A venomous lizard helped inspire Ozempic.
Together, they revealed something interesting: body weight is not simply a matter of willpower. It is regulated by a biological system that actively defends itself.

Obesity is often presented as a simple equation: eat too much, move too little.
However, obesity is 40-70% heritable. Most people who lose large amounts of weight regain it quickly. And the highest obesity rates aren't where many people think.

Ahead of the midterms, John Oliver devotes an entire episode to discussing the rising prominence of extremist beliefs within the Republican Party – from white nationalism to antisemitism – and what it all has to do with Vandy potato chips.

The US military is on a precipice. It is being used for what seems to be crimes, is seeing independence of mind crushed, and there is almost no pushback.
