A Giant Structure in Space Challenges Our Understanding of The Universe

Posted by in category: space travel

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved. In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, almost perfect ring of galaxies, some 1.3 billion light-years in diameter. It doesn’t match any known structure or formation mechanism.

ASTRONAUTS aboard the International Space Station (ISS) have been told to prepare for an urgent evacuation.

The ISS is aging, and is due to be retired by the end of the decade.

Computers normally can’t see optical illusions — but a scientist combined AI with quantum mechanics to make it happen

Posted by in categories: information science, particle physics, quantum physics, robotics/AI

The AI system is dubbed a “quantum-tunneling deep neural network” and combines neural networks with quantum tunneling. A deep neural network is a collection of machine learning algorithms inspired by the structure and function of the brain — with multiple layers of nodes between the input and output. It can model complex non-linear relationships and, unlike conventional neural networks (which include a single layer between input and output) deep neural networks include many hidden layers.

Quantum tunneling, meanwhile, occurs when a subatomic particle, such as an electron or photon (particle of light), effectively passes through an impenetrable barrier. Because a subatomic particle like light can also behave as a wave — when it is not directly observed it is not in any fixed location — it has a small but finite probability of being on the other side of the barrier. When sufficient subatomic particles are present, some will “tunnel” through the barrier.

After the data representing the optical illusion passes through the quantum tunneling stage, the slightly altered image is processed by a deep neural network.

Innovative Water Harvester Offers Hope for Water-Scarce Regions

Posted by in categories: food, neuroscience, security, sustainability

Can water be harvested from the air to help mitigate water scarcity across the globe? This is what a recent study published in Technologies hopes to address as a team of researchers from The Ohio State University have developed a novel device that can provide faster and more efficient methods for harvesting water from the air compared to longstanding devices, also called atmospheric water harvesting (AWH). This study holds the potential to help regions around the world mitigate the need for access to clean drinking water, as approximately 2 billion people suffer from lack of clean drinking water in their respective regions.

“You can survive three minutes without air, three weeks without food, but only three days without water,” said Dr. John LaRocco, who is a research scientist in the Department of Psychiatry and Behavioral Sciences at The Ohio State University and lead author of the study. “But with it, you can begin to solve a lot of problems, like national security, mental health or sanitation, just by improving the accessibility of clean drinking water.”

For the device, the researchers designed a nickel titanium-based dehumidifier with temperature-sensitive materials, resulting in harvesting greater amounts of water at 0.18 milliliters per watts per hour compared to 0.16 milliliters per watts per hour for traditional harvesters after 30 minutes. Additionally, the temperature-sensitive materials help regulate the amount of heat used during the harvesting process, resulting in approximately half the power needed to use the harvester. Finally, the reduced size of the harvester provides mobility to be used anywhere in the world, whereas traditional harvesters tend to be large and require significant amounts of energy to operate.

Physicists Think The Infinite Size of The Multiverse Could Be Infinitely Bigger

Posted by in categories: cosmology, quantum physics

Not only does God play dice, that great big casino of quantum physics could have far more rooms than we ever imagined. An infinite number more, in fact.

Physicists from the University of California, Davis (UCD), the Los Alamos National Laboratory in the US, and the Swiss Federal Institute of Technology Lausanne have redrawn the map of fundamental reality to demonstrate the way we relate objects in physics could be holding us back from seeing a bigger picture.

For about a century, our understanding of reality has been complicated by the theories and observations that fall under the banner of quantum mechanics. Gone are the days when objects had absolute measures like velocity and position.

Healthspan Research Review

Posted by in categories: biotech/medical, life extension, robotics/AI

One prevailing hypothesis is that physical fitness mitigates structural brain changes that contribute to cognitive decline. Recent evidence points to a potential role involving myelin —the insulating sheath surrounding neurons that is crucial for efficient neural signaling and overall cognitive health. Myelination facilitates rapid signal transmission and supports neural network integrity.

The degeneration of myelin in the brain is increasingly recognized as a critical factor contributing to disruptions in neural communication, which may play a significant role in the cognitive decline observed in Alzheimer’s disease and other neurodegenerative disorders. Emerging research suggests that myelin breakdown may even precede the formation of amyloid-beta plaques and neurofibrillary tangles—the hallmark pathological features of Alzheimer’s disease. Advanced imaging studies have detected early myelin degeneration in individuals who later develop Alzheimer’s, indicating that myelin damage could be an initial event in the disease’s progression.

Age-related deterioration of myelin is closely associated with cognitive decline. Reduced white matter integrity—often resulting from myelin damage—is correlated with declines in memory, executive function, and processing speed in older adults. As myelin degradation leads to the slowing of cognitive processes and disrupts the synchronization of neural networks, preserving myelin integrity is essential for sustaining cognitive health across the lifespan.

Breakthrough Technique Could Reveal Alien Communications Between Planets

Posted by in categories: alien life, innovation

A new study by Penn State and the SETI Institute explored alien signal detection in the TRAPPIST-1 system using innovative techniques focused on planetary alignments.

Astronomers have developed a new technique to search for radio signals from planets beyond our solar system, particularly those aligned with both each other and Earth. These signals would be similar to those used for communication with rovers on Mars. Penn State astronomers, in collaboration with scientists at the SETI Institute, spent 28 hours using the Allen Telescope Array (ATA) to scan the TRAPPIST-1 star system for signs of alien technology. This effort represents the longest focused search for radio signals from TRAPPIST-1 to date.

Although no evidence of extraterrestrial technology was found, the project introduced a new method for future searches. The research has been accepted for publication in the Astronomical Journal.
