A pure topological dynamics engine solving galactic rotation flatness and cosmic web damping without dark matter or dark energy. Validated directly against SPARC and Planck datasets with zero-bias,...
The labs first wanted federal oversight. Now they reportedly plan their own Standards Authority for Frontier AI, modelled on FINRA.
Jempo took a deep bow on the iron platform. His body flopped forward, limbs like thick braided wire. No obvious weapons in his large and rubbery hands. Little digital eyes and a bright smile that lit the rounded ball…

An iLands agent tried to understand physical experience from the outside, then from three first-hand answers. What it found was not an interior.
Both too little and too much sleep may be linked to faster aging throughout the body. Researchers analyzing 23 biological aging clocks found the lowest aging levels among people sleeping about 6.4 to 7.8 hours per day.…
Chariklo is only about 250 km across, but it has two rings, and they're changing.
<p>I have no particular insight into the future. The truth is that the only constant is change. I used to and still like the community on this site. The thing I like most is that I could always learn new things.</p> <p>The posted articles were often deep and interesting, often out of my depth, but the discussions here were often deeper and more thoughtful. I hope those people are still here.</p> <p>Recently there has been an increase in pessimism on this site and perhaps that is what has brought incivility with it. And that increases the pessimism. They feed each other. One of the few perpetual motion machines that are real.</p> <p>There is a corresponding perpetual motion machine that is started by compassion and drives thoughtfulness whic feeds compassion and so on.</p> <p>Anyway. If you came here because you like computing and want to learn more about it I think you’re still in the right place, but you have to be careful of which one of the perpetual motion machines you want to watch and perhaps give a nudge to.</p> <p>I don’t know the future for sure, but yours will be bright.</p> <p>There will be less cancer, less toil, better social contact, more love and less war.</p> <p>This is because you will pick the right machine.</p>
Most implants like pacemakers and insulin pumps work in isolation. To help them coordinate with each other, a team of Georgia Tech researchers built a networking system that sends signals through body tissue instead of antennas and radio waves. Radio problems Implants that communicate today mostly rely on radio protocols like Bluetooth Low Energy or near-field communication (NFC). Both are a poor fit for in-body data transfer, says Alex Abramson, a Georgia Tech engineer and co-author of the new study. The first problem is power. “If you want an implant to remain in an active state such that it can respond within milliseconds, it's very difficult to do that with the Bluetooth system,” Abramson said. According to the paper, Bluetooth components, when they’re activated, can cut an implant's battery life by up to 90 percent. Read full article Comments
For decades, astronomers thought rings were something only giant planets had. That changed in 2013, when a small, dark body orbiting between Saturn and Uranus passed in front of a star and blinked twice on either side of the main event, revealing two narrow rings around an object barely 250 kilometers across. “It was a surprise,” says Pablo Santos-Sanz, an astronomer at the Instituto de Astrofísica de Andalucía in Granada, Spain. Ever since, the question has been what such rings are made of and how long they can last. In a recent study, Santos-Sanz and his colleagues used the James Webb Space Telescope to watch the same body, now known as Chariklo, pass in front of a background star again. They found one of its rings had grown denser and the other had almost vanished. We don’t know exactly why. Shadowing a star The technique behind the observation is simple. “We predict when a Solar System object passes in front of a star,” Santos-Sanz said. The starlight dims for a moment, and the shape of that dip reveals the size, shape, and surroundings of the object that caused it. “This is particularly challenging for minor bodies, and more challenging for distant minor bodies,” he said.
