This video’s topic is close to my own research, cosmology. The current standard model of cosmology rests on the “cosmological principle” — the idea that the universe looks, on the average, the same everywhere. Alas, it doesn’t look good for the cosmological principle. Just what does the evidence say and, if it holds up, what does this mean? At the end of this video, you’ll know.

Chinese Scientists Say Quantum Radar Could End Stealth Advantage

Posted by in categories: climatology, education, engineering, quantum physics

A new quantum radar technology developed by a team of Chinese researchers would be able to detect stealth planes, the South China Morning Post is reporting.

The news service reports that the radar technology generates a mini electromagnetic storm to detect objects. Professor Zhang Chao and his team at Tsinghua University’s aerospace engineering school, reported their findings in a paper in Journal of Radars.

A quantum radar is different from traditional radars in several ways, according to the paper. While traditional radars have on a fixed or rotating dish, the quantum design features a gun-shaped instrument that accelerates electrons. The electrons pass through a winding tube of a strong magnetic fields, producing what is described as a tornado-shaped microwave vortex.

Quantum Computers Check Each Other’s Answers in New Error-Correction Approach

Posted by in categories: computing, quantum physics

Quantum computers may be now able to employ a “call-a-friend” tactic to make sure their answers are correct.

In a study published today in Physical Review X, a team of physicists from Vienna, Innsbruck, Oxford, and Singapore designed an error-correction method that lets quantum computers check each other’s answers. While quantum computers are advancing quickly, the devices are still extremely sensitive to outside influences — like heat and cosmic rays — that make them more prone to errors that affect their computations, according to the researchers.

“In order to take full advantage of future quantum computers for critical calculations we need a way to ensure the output is correct, even if we cannot perform the calculation in question by other means,” said Chiara Greganti, a physicist at the University of Vienna.

GM shutting down production at most of its plants in North America

Posted by in categories: computing, transportation

General Motors will shut production at most of its North American plants for a week or two starting next week as the worsening chip shortage takes another bite out of its plans.

GM and other automakers had hoped the chip shortage would be mostly behind them by now. But the surge in Covid cases, especially in Southeast Asia where many of the chip manufacturers are based, has actually created a worsening problem for automakers.

Only a small handful of GM’s plants will remain in operation during the pause. Those plants make full-size SUVs and pickups, as well as some of its sports cars, such as the Camaro and Corvette. That’s because GM is prioritizing the chips it does have on hand for its most popular and profitable vehicles.

Researchers develop a hypercompact CRISPR

Posted by in categories: bioengineering, biotech/medical

Bioengineers have repurposed a “non-working” CRISPR system to make a smaller version of the genome engineering tool. Its diminutive size should make it easier to deliver into human cells, tissues and the body for gene therapy.

New AI Algorithm Improves Brain Stimulation Devices to Treat Disease

Posted by in categories: biotech/medical, information science, robotics/AI

Summary: Novel AI technology allows researchers to understand which brain regions directly interact with each other, which helps guide the placement of electrodes for DBS to treat neurological diseases.

For millions of people with epilepsy and movement disorders such as Parkinson’s disease, electrical stimulation of the brain already is widening treatment possibilities. In the future, electrical stimulation may help people with psychiatric illness and direct brain injuries, such as stroke.

The Difference Between a Scientific Hypothesis, Theory, and Law

Posted by in category: law

Good info.


Nobody is exempt from misunderstanding scientific concepts and/or applying them incorrectly. Statistics from the National Science Board show that Americans scored an average of 5.6 over 9 true-or-false and multiple-choice science-related questions in 2016. Because of the low number of questions, the study is better at differentiating low and medium levels of knowledge than those with higher levels of knowledge. However, the results weren’t much different in previous studies, suggesting that Americans generally have had the same basic levels of science literacy since the beginning of the century.

In this context, we’d like to clear up and emphasize the distinctions between scientific hypothesis, theory, and law, and why you shouldn’t use these terms interchangeably.

Baricitinib: the first immunomodulatory treatment to reduce COVID-19 mortality in a placebo-controlled trial

Posted by in category: biotech/medical

Antibacterial, antifungal, antiviral, and antiparasitic treatments developed in the past century have improved survival outcomes, even in high-mortality conditions such as sepsis, a condition that is mostly caused by bacteria but can also be due to other infections. In the 21st century, of all therapies that have improved the outcomes of patients with sepsis, the appropriate and early administration of antibiotics has been shown to be the most effective therapy to save lives.… See More.
