NASA’s Hubble watches Jupiter’s Great Red Spot Behave Like a Stress Ball

Posted by in category: space

Astronomers have observed Jupiter’s legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises — especially when NASA’s Hubble Space Telescope takes a close-up look at it.

Hubble’s new observations of the famous red storm, collected 90 days between December 2023 to March 2024, reveal that the GRS is not as stable as it might look. The recent data show the GRS jiggling like a bowl of gelatin. The combined Hubble images allowed astronomers to assemble a time-lapse movie of the squiggly behavior of the GRS.

“While we knew its motion varies slightly in its longitude, we didn’t expect to see the size oscillate. As far as we know, it’s not been identified before,” said Amy Simon of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, lead author of the science paper published in The Planetary Science Journal. “This is really the first time we’ve had the proper imaging cadence of the GRS. With Hubble’s high resolution we can say that the GRS is definitively squeezing in and out at the same time as it moves faster and slower. That was very unexpected, and at present there are no hydrodynamic explanations.”

Study Probes how Eating Less Can Extend Lifespan

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

Researchers tracked the health of nearly one thousand mice on a variety of diets to see if these diets would extend the mice’s lifespan. The study was designed to ensure that each mouse was genetically distinct, which allowed the team to better represent the genetic diversity of the human population. By doing so, the results are made more clinically relevant, elevating the study to one of the most significant investigations into aging and lifespan to date.

For nearly a century, laboratory studies have shown consistent results: eat less food, or eat less often, and an animal will live longer. But scientists have struggled to understand why these kinds of restrictive diets work to extend lifespan, and how to best implement them in humans. Now, in a long-awaited study to appear in the Oct. 9 issue of Nature, scientists at The Jackson Laboratory (JAX) and collaborators tracked the health of nearly one thousand mice on a variety of diets to make new inroads into these questions.

The study was designed to ensure that each mouse was genetically distinct, which allowed the team to better represent the genetic diversity of the human population. By doing so, the results are made more clinically relevant, elevating the study to one of the most significant investigations into aging and lifespan to date.

A matter of taste: Electronic Tongue Reveals AI ‘Inner Thoughts’

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

A recently developed electronic tongue is capable of identifying differences in similar liquids, such as milk with varying water content; diverse products, including soda types and coffee blends; signs of spoilage in fruit juices; and instances of food safety concerns. The team, led by researchers at Penn State, also found that results were even more accurate when artificial intelligence (AI) used its own assessment parameters to interpret the data generated by the electronic tongue.

The researchers published their results today (Oct. 9) in Nature.

According to the researchers, the electronic tongue can be useful for food safety and production, as well as for medical diagnostics. The sensor and its AI can broadly detect and classify various substances while collectively assessing their respective quality, authenticity and freshness. This assessment has also provided the researchers with a view into how AI makes decisions, which could lead to better AI development and applications, they said.

New evolution discovery called “nothing short of revolutionary”

Posted by in categories: biotech/medical, evolution, genetics

Imagine doctors being able to predict how a disease might progress in your body based on your genetic makeup, or which treatments would be most effective for you.

This research could bring us one step closer to that reality.

To sum it all up, this new research is shaking up how we think about evolution. Instead of seeing it as a series of random events, the study suggests there’s a level of predictability influenced by gene families and genetic history.

Challenging Quantum Supremacy

Posted by in categories: computing, quantum physics

As the rivalry between quantum and classical computing intensifies, scientists are making unexpected discoveries about quantum systems.

Classical computers outperformed a quantum computer in simulations of a two-dimensional quantum magnet system, showing unexpected confinement phenomena. This discovery by Flatiron Institute researchers redefines the practical limits of quantum computing and enhances understanding of quantum-classical computational boundaries.

Classical computer triumphs over quantum advantage.

Should You Take Experimental Life Extension Drugs?

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

My output on my personal blog has been low lately. That’s largely because I’m pushing hard to finish a complete draft of my book on biostasis. If I can keep up the pace, I expect to finish a draft around the end of the year or in January 2025. The blog entries I have written have been on our group blog for Biostasis Technologies. Subscribers will probably enjoy my October 29 entry:

I look at the origins of effective accelerationism (e/acc) and its unacknowledged roots in extropian transhumanism as well as in several Singularitarian writers. Noah Smith has noted the “extropian enthusiasm” of e/acc. The original essays by the e/acc founders can be difficult to distill down so I outline the basics of e/acc and then survey the many flavors of accelerationism. I point out errors in e/acc’s contrast with transhumanism. That is followed by a critique of the injunction to “follow the will of the universe.” Despite errors and shortcomings I conclude that e/acc is more right than wrong. From the perspective of the central important of life extension, I outline what might be called long/acc or longevity accelerationism.

Webb Telescope Uncovers Bright Ancient Galaxies That Challenge Cosmic Theories

Posted by in category: cosmology

Since its launch, the James Webb Space Telescope has identified early galaxies that shine unexpectedly brightly, suggesting rapid maturity and challenging current cosmological models.

The James Webb Space Telescope (JWST), the largest and most advanced space telescope ever constructed, has been making remarkable discoveries since its launch in December 2021. Among its achievements is the identification of the earliest and most distant galaxies known, which formed just 300 million years after the Big Bang.

Saturday Citations: On chimpanzee playwrights; the nature of dark energy; deep-diving Antarctic seals

Posted by in categories: chemistry, cosmology, physics

This week, researchers reported the world’s second-tiniest toad, winning the silver in the Brachycephalus contest. Chemists at UCLA disproved a 100-year-old organic chemistry rule. And researchers in Kenya report that elephants don’t like bees, which could be a conservation boon (for the elephants. And maybe also the bees?). Additionally, scientists addressed an old thought experiment about monkeys and the theater, physicists correlated dark energy with the black hole population in the universe, and a group of Antarctic seals were found to be highly strategic and also adorable:

Two People Were Able To Communicate In Their Dreams For The First Time Ever In A Groundbreaking Experiment

Posted by in category: neuroscience

Researchers at REMspace, a startup based in California, have reported that two people were able to communicate in their dreams.

The experiment is an example of the potential that lucid dreams have to create new communication methods, pushing the limits of what scientists thought humans were capable of.

The company claimed that two individuals managed to induce lucid dreams with success and shared a simple message using specially designed equipment.
