Physicist Studying SARS-CoV-2 Virus Believes He Has Found Hints We Are Living In A Simulation

Dr. Melvin Vopson’s study delves into the intriguing concept of information entropy, which differs from traditional physical entropy. Physical entropy measures the disorder within a system’s physical states, whereas information entropy pertains to the arrangement and complexity of information within those states.

Vopson applied this principle to the SARS-CoV-2 virus, analyzing its mutations through an information entropy lens. He explained, “The physical entropy of a given system is a measure of all its possible physical microstates compatible with the macrostate…the additional entropy associated with them is called the entropy of information.”

For the first time, scientists make light travel forward and backward in time simultaneously

Posted by in categories: computing, quantum physics

Scientists have, for the first time ever, made light appear to move simultaneously forward and backward in time.

According to a LiveScience report, the new approach, developed by a global team of scientists, may contribute to the development of novel quantum computing methods and advance our understanding of quantum gravity.

Groundbreaking Advance in Brain Science: Creating Human Blood-Brain Barrier ‘Assembloids’

Posted by in categories: biotech/medical, neuroscience, science

In a pioneering achievement, a research team led by experts at Cincinnati Children’s have developed the world’s first human mini-brain that incorporates a fully functional blood-brain barrier (BBB).

This major advance, published May 15, 2024, in Cell Stem Cell, promises to accelerate the understanding and improved treatment of a wide range of brain disorders, including stroke, cerebral vascular disorders, brain cancer, Alzheimer’s disease, Huntington disease, Parkinson’s disease, and other neurodegenerative conditions.

“Lack of an authentic human BBB model has been a major hurdle in studying neurological diseases,” says lead corresponding author Ziyuan Guo, PhD, “Our breakthrough involves the generation of human BBB organoids from human pluripotent stem cells, mimicking human neurovascular development to produce a faithful representation of the barrier in growing, functioning brain tissue. This is an important advance because animal models we currently use in research do not accurately reflect human brain development and BBB functionality.”

World leaders still need to wake up to AI risks, say leading experts ahead of AI Safety Summit

Posted by in category: robotics/AI

Leading AI scientists are calling for stronger action on AI risks from world leaders, warning that progress has been insufficient since the first AI Safety Summit in Bletchley Park six months ago.

Quantum tunnels allow particles to break the light-speed barrier

Posted by in categories: particle physics, quantum physics

In the fascinating realm of quantum physics, particles seem to defy the laws of classical mechanics, exhibiting mind-bending phenomena that challenge our understanding of the universe. One such phenomenon is quantum tunneling.

In quantum tunnels, particles appear to move faster than the speed of light, seemingly breaking the fundamental rules set by Einstein’s theory of relativity.

However, a group of physicists from TU Darmstadt has proposed a new method to measure the time it takes for particles to tunnel, suggesting that previous experiments may have been inaccurate.

Next-Gen LPDDR6 memory to hit up to 14.4 Gbps data rate, DDR6 up to 17.6 Gbps

Posted by in category: energy

The Low Power Double Data Rate 6 (LPDDR6) memory may be introduced with data rates starting from 10.667 Gbps and bandwidth of 32 Gbps. This is the new information coming from the JEDEC presentation, as revealed by Synopsys and published Darkmont. The presentation touches on several topics, including LPDDR, DDR and CAMM standards.

The LPDDR5 standard is already 5 years old, it is time for an update. The mid-product update from Samsung and SK Hynix in a form of LPDDR5X and LPDDR5T are not good enough anymore and in 1–2 years demand for higher bandwidth will unquestionable. Especially given the progress in integrated graphics solutions, which heavily rely on fast system memory.

The DOJ makes its first known arrest for AI-generated CSAM

Posted by in categories: government, robotics/AI

The US Department of Justice arrested a Wisconsin man last week for generating and distributing AI-generated child sexual abuse material (CSAM). As far as we know, this is the first case of its kind as the DOJ looks to establish a judicial precedent that exploitative materials are still illegal even when no children were used to create them. “Put simply, CSAM generated by AI is still CSAM,” Deputy Attorney General Lisa Monaco wrote in a press release.

The DOJ says 42-year-old software engineer Steven Anderegg of Holmen, WI, used a fork of the open-source AI image generator Stable Diffusion to make the images, which he then used to try to lure an underage boy into sexual situations. The latter will likely play a central role in the eventual trial for the four counts of “producing, distributing, and possessing obscene visual depictions of minors engaged in sexually explicit conduct and transferring obscene material to a minor under the age of 16.”

The government says Anderegg’s images showed “nude or partially clothed minors lasciviously displaying or touching their genitals or engaging in sexual intercourse with men.” The DOJ claims he used specific prompts, including negative prompts (extra guidance for the AI model, telling it what not to produce) to spur the generator into making the CSAM.

How to create an efficient network between the Internet of Things and satellite constellations

Posted by in categories: internet, satellites

One of the main barriers involves how to connect objects to the internet in places where there is no mobile network infrastructure. The answer seems to lie with low Earth orbit (LEO) satellites, although the solution presents its own challenges.

A new study led by Guillem Boquet and Borja Martínez, two researchers from the Universitat Oberta de Catalunya (UOC) working in the Wireless Networks (WINE) group of the university’s Internet Interdisciplinary Institute (IN3), has examined possible ways to improve the coordination between the billions of connected objects on the surface of the Earth and the satellites in its atmosphere.

The paper is published in the IEEE Internet of Things Journal.
