“Coinciding with the 50th anniversary of the first MRI, the researchers generated scans of a mouse brain that are dramatically crisper than a typical clinical MRI for humans, the scientific equivalent of going from a pixelated 8-bit graphic to the hyper-realistic detail of a Chuck Close painting. A single voxel of the new images—think of it as a cubic pixel—measures just 5 microns. That's 64 million times smaller than a clinical MRI voxel.” (MedicalXpress)

“OpenAI’s CEO, Sam Altman, says further progress will not come from making models bigger. “I think we're at the end of the era where it's going to be these, like, giant, giant models,” he told an audience at an event held at MIT late last week. “We'll make them better in other ways.” (WIRED)

“The lunar far side is permanently shielded from the radio signals generated by humans on Earth. During the lunar night, it is also protected from the Sun. These characteristics make it probably the most “radio-quiet” location in the whole solar system as no other planet or moon has a side that permanently faces away from the Earth. It is therefore ideally suited for radio astronomy.” (The Conversation)

"If you're having arms control, you need to have some process of validation," he said. "But the signature for developing AI is quite small. You don't need these uranium enrichment facilities, for example. You're talking about warehouses with computers and scientists. How can you monitor potential defection from the arms control regime? There's a huge incentive to cheat on regulation if you believe that these technologies confer profound military advantage. That makes me slightly uncomfortable… I'm slightly skeptical about the prospects for regulation." (The Register)

“SpaceX’s Starship rocket exploded on Thursday, minutes after lifting off from a launchpad in South Texas. The rocket, the most powerful ever built, did not reach orbit but provided important lessons for the private spaceflight company as it worked toward a more successful mission.” (New York Times)
