From the article:
“In a 2024 Science study, researchers performed a high-resolution EM reconstruction of the ultrastructure of a cubic millimeter of human temporal cortex. According to the authors, the reconstruction contains roughly 57,000 cells, about 230 millimeters of blood vessels, and nearly 150 million synapses, comprising 1,400 terabytes of data.”

For fifteen years, NASA told Dan Barry no.
He kept applying. Then he flew three shuttle missions, walked in space four times, and made two trips to the International Space Station. On the mission that didn’t go there, he was outside the orbiter rehearsing how to build it.
In 2011, I ambushed him with a camera at Singularity University and got 20 minutes.
Dan is not just an astronaut. He holds a doctorate in electrical engineering from Princeton and a doctorate in medicine from Miami, and he left NASA in 2005 to build #robotics for people with disabilities. So when our conversation turned to #ArtificialIntelligence, and specifically to what happens when we arm it, he was not speculating. He was describing machines he understood from the inside.
Armed drones were already flying in 2011. What nobody had done yet was hand the machine the decision to fire. Fifteen years on, that line is thinner than most people realize.
We also got into Asimov’s three laws, the Turing test, his 109 project to improve a billion lives in a decade, and whether we survive the #Singularity at all.
In most everyday materials, such as copper, silver and silicon, the behavior of electrons is relatively predictable. In quantum materials, however, electrons can interact in complex ways, giving rise to collective electronic states with remarkable properties. Understanding how these states emerge—and, ultimately, how to control them—is one of the central challenges in quantum materials research.
Now, researchers from the Okinawa Institute of Science and Technology (OIST) and Hiroshima University have discovered that a small magnetic field switches the layered quantum material CeTe₃ between competing electronic states that appear as striped or checkerboard patterns.
Published in Nature Communications, the work reveals how magnetism can reorganize a quantum material’s entire electronic state.
