Staggering numbers of Palestinians now being shot in Gaza as they try to find food at GHF sites, or along UN convoy routes. More than 4,500 people treated in a single Red Cross clinic. Almost 1,400 across two MSF clinics. Total is more than 12,000, according to health ministry.

Portrait of neuroscientist Nikolay Kukushkin wearing a grey turtleneck

POV: You’re a cell. You don’t have a brain. How do you form memories? It’s a perspective that the biologist Nikolay Kukushkin is used to inhabiting. “Really, when I close my eyes, I’m inside the cell,” he said.

Forgotten studies from the early 20th century are helping scientists probe how and whether individual cells can learn and remember.

What can a cell remember? A lot more than you think. My latest, for @quantamagazine.bsky.social, is on memory beyond the brain—in tiny unicellular creatures and the smallest, most ancient parts of ourselves:

Most of us have a hard time stepping outside our subjective experience to imagine what memory might look like for a cell. But for the neuroscientist Nikolay Kukushkin it’s an easy leap. “Really, when I close my eyes, I’m inside the cell."

If you’ve ever tried to cram for an exam, you know that it’s easier to memorize something if you learn the information in shorter, spaced-out sessions. These dynamics are as relevant to each individual cell’s existence as they are to ours. Claire Evans reports: www.quantamagazine.org/what-can-a-c...

Take a deep breath. You’re using oxygen to free molecular energy from the food you eat. But not all organisms on the planet live or breathe this way. @jakebuehler.bsky.social reports: www.quantamagazine.org/the-cells-th...

A Palestinian doctor in Gaza shared the following urgent message with Drop Site:

“Today is the first day that hospitals run by the Ministry of Health in Gaza have stopped providing meals to medical staff.”

Meals for patients and medical teams have now been cut. He warns this means many patients are facing “certain death.”

Patients will no longer receiving proper nutrition, leaving them unable to recover or resist illness.

“Second, and even more dangerous, is that healthcare workers themselves are now exhausted and will be unable to continue treating patients.”

He echoed the Health Ministry in describing the situation as “catastrophic,” and urged soup kitchens and food aid initiatives to immediately redirect their efforts toward hospitals.

GHF operates four sites concentrated in southern Gaza and staffed at least in part by US security contractors, working under Israeli military supervision.

The signal for Gazans to set off from their tents or the ruins of their homes often comes from GHF’s Facebook page, where it announces the opening times of its distribution sites.

These posts sometimes appear in the middle of the night and can give less than 30 minutes notice, an FT analysis found. A second post, often published only minutes after the scheduled opening times, announces the site is closed, with all aid distributed. In some cases, GHF has declared the site closed even before it was due to open.

Frequent internet outages in Gaza can also make it difficult for Palestinians even to access Facebook to see the posts.

But for aid seekers, who must walk for kilometres along barely discernible routes whose landmarks have been flattened by Israel’s 21-month offensive, there is little room for miscalculation.

“You don’t see where you are going in the dark,” said Jihad. “The route is provided as a map on your phone screen but on the ground the roads are all destroyed and you have to take a chance. So either you are on the right route, or you die.”

The #1 way to explain America working properly is by saying “comedians can make fun of he President on TV.” A good way to explain fascism is “the President forces companies to fire those comedians as a condition of allowing them to conduct business.”

I've been saying to friends for a few months that the more I study authoritarianism in other countries, the more concerned I become that the CBS story is the sleeping giant here. The process has been a simmer (people inside the network have spoken out in real-time) but don't mistake slow for safe.

I spent years posting about the humanitarian crisis in U.S. prisons. The criminal legal system consigns Americans who are incarcerated to live like this FOR YEARS. DECADES.
