A flu strain that emerged over the summer is causing outbreaks in other countries. The CDC hasn't provided any insights on what's happening in the U.S. in weeks.

A Robotaxi Killed a Beloved Bodega Cat in San Francisco. People Are Pissed
KitKat, known as the "Mayor of 16th Street," was killed by a Waymo cab last week. Now, some are callings for more regulation of driverless cars.

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).

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
