Putting an atom into a hall of mirrors ("cavity") can stop it from emitting light. Now remove a mirror. How long before the atom can emit? Immediately! No matter how long the hallway. Vlatko Vedral of @imperialcollegeldn.bsky.social explains this bizarre case of quantum spooky action at a distance.
It’s All (Quantum) Smoke and Mirrors
Issue #57 ~ As my readers will know, I have been advocating a picture of the universe in which the underlying reality consists of quantum waves. Quantum, meaning that the height of the wave and its ph...

Tech companies are spending $1 trillion on A.I. China built its entire high-speed rail network for that. It's hard to imagine A.I. would improve our lives by as much as a decent transit system (not to mention universal health care or poverty elimination).

Mindblowing study of a 3800-year-old array of termite mounds in the caatinga shrubland of northeastern Brazil—200 million of them interconnected by tunnels over an area the site of Britain.
A vast 4,000-year-old spatial pattern of termite mounds
Martin et al. show that in Northeast Brazil an estimated 200 million, regularly spaced,
termite mounds are up to 4000 years old. Each mound is 2-4m high by 9 m in diameter;
they occupy 230,000 km2, an...

CO2 levels in Earth's atmosphere jumped by a record amount in 2024
The global average concentration of CO2 surged by 3.5 parts per million to reach 423.9 ppm last year, fuelling worries that the planet’s ability to soak up excess carbon is weakening

Hey #ALIFE2025 people! Have you heard of Assembly Theory? A month ago, I wrote a good, objective essay summarizing AT's contributions, limitations, and possible improvements. It's perfect if you don't want to read all the critiques and counter-critiques that have been written!
As a promising avenue for unifying physics and biology, assembly theory (AT) has been subject of controversy, being both praised and refuted at the same time.
What is its current status? Has it really quantified selection and evolution?/1
