Using Wobbling Stellar Material, astronomers measure the Spin of a Supermassive Black Hole for the first time

Posted by in categories: cosmology, materials

Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting.

The method takes advantage of a black hole tidal disruption event—a blazingly bright moment when a black hole exerts tides on a passing star and rips it to shreds. As the star is disrupted by the black hole’s immense tidal forces, half of the star is blown away, while the other half is flung around the black hole, generating an intensely hot accretion disk of rotating stellar material.

The MIT-led team has shown that the wobble of the newly created accretion disk is key to working out the central black hole’s inherent spin.

The Blood of Exceptionally Long-Lived People Reveals Crucial Differences

Posted by in categories: biotech/medical, genetics, life extension

Centenarians, once considered rare, have become commonplace. Indeed, they are the fastest-growing demographic group of the world’s population, with numbers roughly doubling every ten years since the 1970s.

How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and wrote about the ageing process over 2,300 years ago.

The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however. It involves unravelling the complex interplay of genetic predisposition and lifestyle factors and how they interact throughout a person’s life.

“Spooky action at a distance” confirmed in heaviest particles

Posted by in categories: particle physics, quantum physics

Physicists have delved deeper into the enigmatic world of quantum entanglement and top quarks, bringing a new level of understanding to a phenomenon that even Albert Einstein found perplexing.

This incredible feat has the potential to revolutionize our understanding of the quantum realm and its far-reaching implications.

The experiment, conducted by a team of researchers led by University of Rochester physics professor Regina Demina at the European Center for Nuclear Research (CERN), has yielded a significant result.

Self-assembling and disassembling swarm molecular robots via DNA molecular controller

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

Researchers from Tohoku University and Kyoto University have successfully developed a DNA-based molecular controller that autonomously directs the assembly and disassembly of molecular robots. This pioneering technology marks a significant step towards advanced autonomous molecular systems with potential applications in medicine and nanotechnology.

Details of the breakthrough were published in the journal Science Advances (“Autonomous assembly and disassembly of gliding molecular robots regulated by a DNA-based molecular controller”).

“Our newly developed molecular controller, composed of artificially designed DNA molecules and enzymes, coexists with molecular robots and controls them by outputting specific DNA molecules,” points out Shin-ichiro M. Nomura, an associate professor at Tohoku University’s Graduate School of Engineering and co-author of the study. “This allows the molecular robots to self-assemble and disassemble automatically, without the need for external manipulation.”

How to opt out of Meta’s AI training

Posted by in categories: internet, robotics/AI

Internet data scraping is one of the biggest fights in AI right now. Tech companies argue that anything on the public internet is fair game, but they are facing a barrage of lawsuits over their data practices and copyright. It will likely take years until clear rules are in place.

In the meantime, they are running out of training data to build even bigger, more powerful models, and to Meta, your posts are a gold mine.

If you’re uncomfortable with having Meta use your personal information and intellectual property to train its AI models in perpetuity, consider opting out. Although Meta does not guarantee it will allow this, it does say it will “review objection requests in accordance with relevant data protection laws.”

A new evolutionary frontier

Posted by in categories: evolution, futurism

Scientists can’t address the origins of life without having a basic understanding of evolution.

You’d think that would make the origins of life a popular research topic for evolutionary biologists. But Maria Kalambokidis, Ph.D. candidate in Ecology, Evolution and Behavior, and recent recipient of the NASA Future Investigators Fellowship, may be one of only a handful across the globe investigating the topic. She thinks it might be because the origins of life, also called abiogenesis, has mostly been studied by chemists.

“It’s difficult to come into the field when you have a completely different scientific background than someone else,” says Kalambokidis. “There are insights from evolution that you might miss by only taking the perspective of a chemist.”
