Scientists have found that a physical property called ‘quantum negativity’ can be used to take more precise measurements of everything from molecular distances to gravitational waves.

The researchers, from the University of Cambridge, Harvard and MIT, have shown that can carry an unlimited amount of information about things they have interacted with. The results, reported in the journal Nature Communications, could enable far more precise measurements and power new technologies, such as super-precise microscopes and quantum computers.

Metrology is the science of estimations and measurements. If you weighed yourself this morning, you’ve done metrology. In the same way as is expected to revolutionize the way complicated calculations are done, quantum metrology, using the strange behavior of subatomic particles, may revolutionize the way we measure things.

The Consumer Electronics Show (CES), long the world’s largest tech trade show, will be all-digital in January 2021, the Consumer Technology Association (CTA) announced on Monday. The CTA cited the COVID-19 pandemic and concerns about the spread of the virus as its reasoning for canceling the in-person event.

CES usually takes place in Las Vegas and involves many large gatherings in tightly packed convention halls, as well as smaller meetings between retailers, manufacturers, and other industry professionals.

Per the CTA, the digital CES will be a “new immersive experience.” The organization did not provide many details about what the online event will look like, but it claims it will be “highly personalized.” The organization still plans to hold CES 2022 in Las Vegas.

How true?

This video is about driverless cars and why China could be ahead of the world in self-driving car technology. We talk about how they are the biggest adopters of autonomous vehicles and how one day Chinese companies could be giving us a future of true autonomous travel. We also look at the issues that may set China back. Let’s take a look at why.

“Just the nature of the AI that they’re building is one that crushes all humans at all games,” Musk told The New York Times in an interview published on Saturday. “I mean, it’s basically the plotline in ‘War Games.’”

DeepMind declined to comment when contacted by CNBC.

Musk has repeatedly warned that AI will soon become just as smart as humans and said that when it does we should all be scared because humanity’s very existence is at stake.

SpaceX is ready to return its first NASA astronaut crew to Earth, but a potential tropical cyclone brewing in the Atlantic could cause delays.

The SpaceX Crew Dragon spacecraft, called Endeavour, is scheduled to splash down off the Florida coast on Sunday afternoon (Aug. 2). Its crew, NASA’s Bob Behnken and Doug Hurley, is wrapping up a historic two-month test flight, the first orbital trip by astronauts on a commercial spacecraft. Their splashdown will also mark the first water landing by American astronauts since the Apollo-Soyuz mission in July 1975.

Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts of stored magnetic energy due to changes in the magnetic field of the sun’s outer atmosphere—something that until now has eluded scientists’ direct measurement. Researchers believe this recent discovery could lead to better “space weather” forecasts in the future.

“We are becoming increasingly dependent on space-based systems that are sensitive to space weather. Earth-based networks and the electrical grid can be severely damaged if there is a large eruption,” says Tomas Brage, Professor of Mathematical Physics at Lund University in Sweden.

Solar flares are bursts of radiation and charged particles, and can cause on Earth if they are large enough. Currently, researchers focus on sunspots on the surface of the sun to predict possible eruptions. Another and more direct indication of increased would be changes in the much weaker of the outer solar atmosphere—the so-called Corona.
