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.

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.

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.

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.

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.

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.

Funders of a deep-pocketed new “rejuvenation” startup are said to include Jeff Bezos and Yuri Milner.

- Welcome back to Yahoo Finance Live. Deeper space exploration missions come with their own set of challenges. Not only are instruments farther away, which make the delay in reacting to certain things difficult, but tricky terrain on the Martian surface has made wheel travel less ideal, as well. And that has researchers turning the Boston Dynamics dog-like robot— you may remember that one from a lot of viral videos— SPOT, as it’s called, for potential solutions.
