Astronomers have discovered a mysterious stream of ancient stars at the distant edges of the galaxy: a strange stellar breed so unlike any we’ve seen before, they may very well be the last of their kind.

This unusual collection of stars – called the ‘Phoenix stream’, after the Phoenix constellation in which they are visible – is what’s known as a stellar stream: an elongated chain of stars that used to exist in a spherical form, known as a globular cluster.

Such clusters can be torn asunder by a galaxy’s gravitational forces, in which case their globular form becomes warped, stretching out into a ghostly caravan of stars, fated to distantly orbit a faraway galactic core.

Ultimately, the MIT engineers hope that their giant atoms lead to a simpler, enhanced form of quantum computers.

“This allows us to experimentally probe a novel regime of physics that is difficult to access with natural atoms,” MIT engineer Bharath Kannan said in a press release. “The effects of the giant atom are extremely clean and easy to observe and understand.”

Nearly 200 covid-19 vaccines are in development and some three dozen are at various stages of human testing. But in what appears to be the first “citizen science” vaccine initiative, Estep and at least 20 other researchers, technologists, or science enthusiasts, many connected to Harvard University and MIT, have volunteered as lab rats for a do-it-yourself inoculation against the coronavirus. They say it’s their only chance to become immune without waiting a year or more for a vaccine to be formally approved.


Preston Estep was alone in a borrowed laboratory, somewhere in Boston. No big company, no board meetings, no billion-dollar payout from Operation Warp Speed, the US government’s covid-19 vaccine funding program. No animal data. No ethics approval.

What he did have: ingredients for a vaccine. And one willing volunteer.

Estep swirled together the mixture and spritzed it up his nose.

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.

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.
