Fed on Reams of Cell Data, AI Maps New Neighborhoods in the Brain | Quanta Magazine Machine learning is helping neuroscientists organize vast quantities of cells’ genetic data in the latest neurobiological cartography effort.

Biologists have fed genetic data from millions of mouse brain cells into a custom machine learning algorithm. The program delivered maps of the brain with unprecedented detail, revealing a thousand-plus novel regions.

For a long time, astrocytes were considered mere support and scaffolding for all-important neurons. The new experiments reveal in great detail the cells’ influence over neuronal signaling in the brain.

I Infiltrated Moltbook, the AI-Only Social Network Where Humans Aren’t Allowed I went undercover on Moltbook and loved role-playing as a conscious bot. But rather than a novel breakthrough, the AI-only site is a crude rehashing of sci-fi fantasies.

Journalism coops seem utopian. What’s it like working in one? "If I was less self-directed, I'd probably be freaking out."

Journalism coops give me β€” and most of the journalists I know β€” a lot of hope for the industry. But I've been curious: What's it like to actually work at one? I spent the last few months talking to a bunch of brilliant worker-owners to find out.

Astrocytes have complex and varied shapes, and sometimes tendrils, that can reach millions of synapses, the junctions where neurons exchange molecular signals. This anatomical arrangement perfectly positions astrocytes to affect information flow.

In many of the first generation of modern concentration camp systems (near the turn of the twentieth century), the vast majority of deaths were caused by disease and malnutrition. Most of the victims were women and children.

ICE Begins Buying β€˜Mega’ Warehouse Detention Centers Across US Plans for such centers and jails in nearly two dozen communities have sparked protests over suitability, proximity to homes and schools.

BIG news from @bloomberg.com, which confirms that ICE has gone ahead and *purchased* multiple commercial warehouses with the aim of converting them into mass detention camps.

This is likely to be the big detention story of 2026 β€” literal warehousing of people.

After being held in two of them as a boy, I fought for decades urging America to never again build concentration camps and put human beings in them. It breaks my heart to watch this happen twice now in my own lifetime.
