The case for why our Universe may be a giant neural network

Posted by in categories: mathematics, robotics/AI, space

For example, scientists have recently emphasized that the physical organization of the Universe mirrors the structure of a brain. Theoretical physicist Sabine Hossenfelder — renowned for her skepticism — wrote a bold article for Time Magazine in August of 2022 titled “Maybe the Universe Thinks. Hear Me Out,” which describes the similarities. Like our nervous system, the Universe has a highly interconnected, hierarchical organization. The estimated 200 billion detectable galaxies aren’t distributed randomly, but lumped together by gravity into clusters that form even larger clusters, which are connected to one another by “galactic filaments,” or long thin threads of galaxies. When one zooms out to envision the cosmos as a whole, the “cosmic web” formed by these clusters and filaments looks strikingly similar to the “connectome,” a term that refers to the complete wiring diagram of the brain, which is formed by neurons and their synaptic connections. Neurons in the brain also form clusters, which are grouped into larger clusters, and are connected by filaments called axons, which transmit electrical signals across the cognitive system.

Hossenfelder explains that this resemblance between the cosmic web and the connectome is not superficial, citing a rigorous study by a physicist and a neuroscientist that analyzed the features common to both, and based on the shared mathematical properties, concluded that the two structures are “remarkably similar.” Due to these uncanny similarities, Hossenfelder speculates as to whether the Universe itself could be thinking.

Reindeer show great performance at following human-given indications

Posted by in category: futurism

An international team of researchers from the University of Turku, Finland, and the INRAE of Nouzilly, France, explored the ability of sledging reindeer to follow directional indications from humans. Their results highlight that reindeer, which are well habituated to humans, can make use of gestural cues very well with minimal training.

Working , such as equines, shepherd dogs, and logging elephants, spend a significant amount of time interacting closely with humans to fulfill specific tasks. Effective communication plays a crucial role in their working relationship. Animals’ understanding of cues, particularly manual pointing gestures, is an important aspect of this communication.

The use of pointing gestures to communicate with others and to show them where to look or to go is very natural for humans. For other animals that do not use this way of communication, the may not always be easy to understand. For this reason, the pointing gesture is often used in experiments to see if animals can understand cues that are specific to humans.

Engineered white blood cells can eliminate cancer, shows study

Posted by in categories: biotech/medical, chemistry, engineering, neuroscience

Cancer remains one of the leading causes of death in the US at over 600,000 deaths per year. Cancers that form solid tumors such as in the breast, brain, or skin are particularly hard to treat. Surgery is typically the first line of defense for patients fighting solid tumors. But surgery may not remove all , and leftover cells can mutate and spread throughout the body. A more targeted and wholistic treatment could replace the blunt approach of surgery with one that eliminates cancer from the inside using our own cells.

Dennis Discher, Robert D. Bent Professor of Chemical and Biomolecular Engineering, and postdoctoral fellow Larry Dooling provide a new approach in targeted therapies for solid tumor cancers in their study, published in Nature Biomedical Engineering. Their therapy not only eliminates cancerous cells, but teaches the to recognize and kill them in the future.

How car tires are retreaded

Posted by in categories: chemistry, transportation

The disposal of tires represents a significant burden on the environment, so companies like Marangoni developed methods to recycle and reuse old tires. Watch how retreading machines make old tires usable again.

Following is a transcript of the video.

Narrator: When your tire wears out, you take it to a shop where it’s tossed out for a new one. The discarded tire is typically recycled — ground up and chemically broken down to use as a building material in streets or parks. Some companies hope to recycle differently. For years, companies like Marangoni have been saving tire casings, replacing the old tread (the rubber that touches the ground) with new tread in a process called “retreading.” These tires are not only easier to make — they typically take 20% of the energy of creating a new tire — they perform well too, standing up to the same tests that one-use tires are subjected to.

World’s first ‘battery tanker’ to debut in 2026

Posted by in categories: energy, futurism

Japanese company PowerX has unveiled the detailed design of the first-ever “Battery Tanker” at the Bariship International Maritime Exhibition held in Imabari City, Ehime Prefecture, Japan.

For over a century, oil tankers have been a familiar sight on international shipping routes, delivering vital energy sources to power our civilisation. But as the world shifts away from fossil fuels, they could soon be joined by new and futuristic-looking vessels bringing cleaner forms of energy.

Team develops a novel, completely solid, rechargeable air battery

Posted by in category: materials

Metals are typically used as active materials for negative electrodes in batteries. Recently, redox-active organic molecules, such as quinone-and amine-based molecules, have been used as negative electrodes in rechargeable metal–air batteries with oxygen-reducing positive electrodes. Here, protons and hydroxide ions participate in the redox reactions. Such batteries exhibit high performance, close to the maximum capacity that is theoretically possible.

Furthermore, using redox-active organic molecules in rechargeable air batteries overcomes problems associated with metals, including the formation of structures called ‘dendrites,’ which impact battery performance, and have negative environmental impact. However, these batteries use liquid electrolytes—just like metal-based batteries—which pose major safety concerns like high electrical resistance, leaching effects, and flammability.

Now, in a recent study published in Angewandte Chemie International Edition, a group of Japanese researchers have developed an all-solid-state rechargeable air battery (SSAB) and investigated its capacity and durability. The study was led by Professor Kenji Miyatake from Waseda University and the University of Yamanashi, and co-authored by Professor Kenichi Oyaizu from Waseda University.

Forget space tourism. This company wants to make drug manufacturing the next big extraterrestrial business

Posted by in categories: biotech/medical, business, satellites

One California-based startup, Varda Space Industries, is betting that big business will lie in relatively unassuming satellites that will spend days or months in Earth’s orbit quietly carrying out pharmaceutical development. Its research, company officials hope, could lead to better, more effective drugs — and hefty profits.

“It’s not as sexy a human-interest story as tourism when it comes to commercialization of the cosmos,” said Will Bruey, Varda’s CEO and cofounder. “But the bet that we’re making at Varda is that manufacturing is actually the next big industry that gets commercialized.”

Varda is expected to launch its first test mission Monday aboard a SpaceX rocket. A window for take-off from Vandenberg Space Force Base in California begins at 2:19 p.m. PT.
