Cutting Back on One Amino Acid Increases Lifespan of Mice Up to 33%

Posted by in category: life extension

Research in mice shows limited intakes of one particular essential amino acid can slow the impacts of aging and even lengthen their lifespan.

Scientists are now wondering if these findings could help people improve their longevity and quality of life.

Isoleucine is one of three branched-chain amino acids we use to build proteins in our bodies. It is essential for our survival, but since our cells can’t produce it from scratch, we have to get it from sources like eggs, dairy, soy protein and meats.

Sam Altman Shuts Down Q* Questions

Posted by in category: robotics/AI

OpenAI CEO Sam Altman is remaining tight-lipped about the company’s secretive Q* project — even after admitting that his company is something of a leaky ship.

Even among those who followed along with OpenAI’s November massacre that saw Altman temporarily ousted, it’s easy to overlook the Q* (pronounced “queue-star”) of it all, particularly because nobody outside the company really knows what the heck it is.

Quadriplegic Patient Plays Chess With His Mind Using New Neuralink Chip

Posted by in categories: biotech/medical, computing, Elon Musk, neuroscience

Neuralink, Elon Musk ’s brain chip startup, released a video on Wednesday showing the company’s first patient using a laptop with just his mind.

The video, which was livestreamed on Neuralink’s account on X, showed 29-year-old Noland Arbaugh playing a game of chess on his laptop using Neuralink’s brain computer interface (BCI) technology. Arbaugh is paralyzed from the shoulders down due to what he describes as a “freak diving accident.”

“It’s all brain power there,” Arbaugh said, referring to his ability to use a mouse and keyboard unassisted. He later added, “Basically, it was like using the Force on the cursor and I could get it to move wherever I wanted.”

Pushing the limit of the periodic table with superheavy elements

Posted by in categories: chemistry, particle physics

Scientists from Massey University in New Zealand, the University of Mainz in Germany, Sorbonne University in France, and the Facility for Rare Isotope Beams (FRIB) discuss the limit of the periodic table and revising the concept of the “island of stability” with recent advances in superheavy element research. Their work first appeared in Nature Reviews Physics.

In addition to the Nature Reviews Physics, Physics Reports has published a review on the atomic electronic structure theory for superheavy elements.

What is the heaviest bound nucleus and the heaviest bound atom and what are their properties? The nuclei of chemical elements with more than 103 protons are labeled as “superheavy.” They are part of a vast unknown territory of these nuclei that scientists are trying to uncover. Exploring this uncharted territory provides prospects for discoveries that connect the broad areas of science.

Video: Unitree H1 is first humanoid to nail a backflip without hydraulics

Posted by in category: robotics/AI

After setting a new world speed record for humanoid robots earlier this month, China’s Unitree is now claiming another. Its latest H1 bipedal takes the title for first to perform a standing backflip without the use of hydraulics.

Yes, humanoids like Boston Dynamics’ Atlas have been nailing backflips for a few years now but they make use of heavy, potentially leaky hydraulics to launch into the air, somersault backwards and then land on both feet.

New Study Suggests A ‘Dark Mirror’ Parallel Universe May Exist Right Alongside Ours

Posted by in category: cosmology

Think the Upside Down in Stranger Things is a work of fiction? Well, it is, but something eerily reminiscent of the Upside Down – dark matter, or a “dark mirror” universe – is being studied and taken very seriously by scientists.

So what exactly is dark matter? NASA explains, Like ordinary matter, dark matter takes up space and holds mass. But it doesn’t reflect, absorb, or radiate light – at least not enough for us to detect yet.

What is emergent gravity, and will it rewrite physics?

Posted by in categories: cosmology, evolution, physics

In Verlinde’s picture of emergent gravity, as soon as you enter low-density regions — basically, anything outside the solar system — gravity behaves differently than we would expect from Einstein’s theory of general relativity. At large scales, there is a natural inward pull to space itself, which forces matter to clump up more tightly than it otherwise would.

This idea was exciting because it allowed astronomers to find a way to test this new theory. Observers could take this new theory of gravity and put it in models of galaxy structure and evolution to find differences between it and models of dark matter.

Over the years, however, the experimental results have been mixed. Some early tests favored emergent gravity over dark matter when it came to the rotation rates of stars. But more recent observations haven’t found an advantage. And dark matter can also explain much more than galaxy rotation rates; tests within galaxy clusters have found emergent gravity coming up short.
