Eduard Shyfrin, Ph.D., author of “From Infinity to Man: The Fundamental Ideas of Kabbalah Within the Framework of Information Theory and Quantum Physics,” addressed attendees at the eighteenth World Union of Jewish Studies Conference in Jerusalem on Monday.

Shyfrin spoke via Zoom on Kabbalah of Information: Absence of Information is Information’. He explained how Kabbalistic ideas can be explained using the support of information theory and physics.

When young, these neurons signal fatty tissues to release energy fueling the brain. With age, the line breaks down. Fat cells can no longer orchestrate their many roles, and neurons struggle to pass information along their networks.

Using genetic and chemical methods, the team found a marker for these neurons—a protein called Ppp1r17 (catchy, I know). Changing the protein’s behavior in aged mice with genetic engineering extended their life span by roughly seven percent. For an average 76-year life span in humans, the increase translates to over five years.

The treatment also altered the mice’s health. Mice love to run, but their vigor plummets with age. Reactivating the neurons in elderly mice revived their motivation, transforming them from couch potatoes into impressive joggers.

A team of researchers from the Structured Light Laboratory at the University of the Witwatersrand, South Africa, has made a significant breakthrough regarding quantum entanglement.

Led by Professor Andrew Forbes, in collaboration with renowned string theorist Robert de Mello Koch, now at Huzhou University in China, the team has successfully demonstrated a novel method to manipulate quantum entangled particles without altering their intrinsic properties.

This feat marks a monumental step in our understanding and application of quantum entanglement.

Putting “socks” on artificial muscles made from inexpensive materials helps them produce 40 times more flex than human muscle, a global research project has found, featuring researchers from the University of Wollongong (UOW) at the ARC Centre of Excellence for Electromaterials Science (ACES).

UOW researchers from ACES joined with international partners from the U.S., China and South Korea to develop sheath-run artificial muscles (SRAMs), that can be used to create intelligent materials and fabrics that react by sensing the environment around them.

It builds on the work over the past 15 years by researchers from UOW and their international colleagues who have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon nanotubes (CNTs) to ordinary fishing line.

The organization of electrolytes at the air/water interface affects the structure of interfacial water and therefore numerous natural processes. It has now been demonstrated that the surface of an electrolyte solution is stratified and consists of an ion-depleted outer surface and an ion-enriched subsurface layer, jointly determining the water interfacial structure.

A groundbreaking study by researchers from a number of institutions in China introduces a novel hyperspectral remote sensing technique capable of hour-hectometer level horizontal distribution of trace gases, offering an advanced tool to accurately identify emission sources.

The study was published in the Journal of Remote Sensing on 14 November 2023.

The research introduces a groundbreaking hyperspectral remote sensing method that delivers highly accurate, hour-hectometer-level insights into the horizontal distribution of atmospheric trace gases. This advanced technique utilizes effective optical paths (EOPs) within the ultraviolet (UV) and visible (VIS) spectral bands to measure average trace gas concentrations across various distances.

It’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope picked up something no one had ever seen before: radio wave circles so large they contained entire galaxies in their centers.

As the astrophysics community tried to determine what these circles were, they also wanted to know why the circles were. Now a team led by University of California San Diego Professor of Astronomy and Astrophysics Alison Coil believes they may have found the answer: the circles are shells formed by outflowing galactic winds, possibly from massive exploding stars known as supernovae. Their work is published in Nature.

Coil and her collaborators have been studying massive “starburst” galaxies that can drive these ultra-fast outflowing winds. Starburst galaxies have an exceptionally high rate of star formation. When stars die and explode, they expel gas from the star and its surroundings back into interstellar space. If enough stars explode near each other at the same time, the force of these explosions can push the gas out of the galaxy itself into outflowing winds, which can travel at up to 2,000 kilometers/second.

Hyperion, a California-based company, has unveiled a hydrogen-powered supercar the company hopes will change the way people view hydrogen fuel cell technology.

The Hyperion XP-1 will be able to drive for up to 1,000 miles on one tank of compressed hydrogen gas and its electric motors will generate more than 1,000 horsepower, according to the company. The all-wheel-drive car can go from zero to 60 miles per hour in a little over two seconds, the company said.

Hydrogen fuel cell cars are electric cars that use hydrogen to generate power inside the car rather than using batteries to store energy. The XP-1 doesn’t combust hydrogen but uses it in fuel cells that combine hydrogen with oxygen from the air in a process that creates water, the vehicle’s only emission, and a stream of electricity to power the car.

In the fifth decade of life, our brains start to undergo a radical “rewiring” that results in diverse networks becoming more integrated over the ensuing decades. ⁠ https://bigthink.com/neuropsych/great-brain-rewiring-after-age-40/ Big Think.

In a systematic review published last year in the journal Psychophysiology, researchers from Monash University in Australia swept through the scientific literature, seeking to summarize how the connectivity of the human brain changes over our lifetimes. The gathered evidence suggests that in the fifth decade of life (that is, after a person turns 40), the brain starts to undergo a radical “rewiring” that results in diverse networks becoming more integrated and connected over the ensuing decades, with accompanying effects on cognition.

Since the turn of the century, neuroscientists have increasingly viewed the brain as a complex network, consisting of units broken down into regions, sub-regions, and individual neurons. These units are connected structurally, functionally, or both. With increasingly advanced scanning techniques, neuroscientists can observe the parts of subjects’ brains that “light up” in response to stimuli or when simply at rest, providing a superficial look at how our brains are synced up.
