The new fiber could help satisfy demand for 6G and beyond.

The many-gigabit internet speed records of a decade ago now seem downright inadequate. Motherboard reports that scientists at Japan's National institute of Information and Communications Technology (NICT) have smashed the internet transfer record by shuffling data at 319Tbps. For context, that's almost twice as fast as the 179Tbps a team of British and Japanese researchers managed in August 2020.

NICT managed the feat by upgrading virtually every stage of the pipeline. The fiber optic line had four cores instead of one, and researchers fired a 552-channel comb laser at multiple wavelengths with the assistance of rare earth amplifiers. While the test was strictly confined to the lab, the team used coiled fiber to transfer data at a simulated 1,864-mile distance without losing signal quality or speed.

Originally built to speed up calculations, a machine-learning system is now making shocking progress at the frontiers of experimental quantum physics.

Quantum physicist Mario Krenn remembers sitting in a café in Vienna in early 2016, poring over computer printouts, trying to make sense of what MELVIN had found. MELVIN was a machine-learning algorithm Krenn had built, a kind of artificial intelligence. Its job was to mix and match the building blocks of standard quantum experiments and find solutions to new problems. And it did find many interesting ones. But there was one that made no sense.

“The first thing I thought was, ‘My program has a bug, because the solution cannot exist,’” Krenn says. MELVIN had seemingly solved the problem of creating highly complex entangled states involving multiple photons (entangled states being those that once made Albert Einstein invoke the specter of “spooky action at a distance”). Krenn and his colleagues had not explicitly provided MELVIN the rules needed to generate such complex states, yet it had found a way. Eventually, he realized that the algorithm had rediscovered a type of experimental arrangement that had been devised in the early 1990s. But those experiments had been much simpler. MELVIN had cracked a far more complex puzzle.

When Microsoft said that it was going to announce the next version of Windows on June 24, it was only a matter of time before the leaks started coming. The first Windows 11 build leaked today, first offering up some screenshots on Baidu. Now, the full build is here.

First of all, we should be clear that this is very much a new version of Windows 10. It has a big visual redesign, but under the hood, this is the same OS. Microsoft wanted to build excitement around it, so that’s why we’re getting the new branding. Because of this, the first thing you’ll see when booting up this leaked build is a very familiar out-of-box experience.

Indeed, all of the different Windows 11 versions are the same as they were for Windows 10, including Home, Pro, Enterprise, and more. Once you get past that part where you choose your edition, decide how to partition your drive, and it actually installs the bits, that’s where the OOBE takes a left turn from what’s familiar.

NASA's new chief is setting up an effort to further study unidentified flying objects within his first month in office.

Bill Nelson, the former Florida senator and spaceflight veteran, told CNN Business' Rachel Crane during a wide-ranging interview on Thursday that it's not clear to anyone — even in the upper echelons of the US space agency — what the high-speed objects observed by Navy pilots are.

Nelson added that he does not believe the UFOs are evidence of extraterrestrials visiting Earth. "I think I would know" if that were the case, Nelson said. But, he acknowledged, it'd be premature to rule that out as a possibility.

Nelson's comments echo the findings of a new Pentagon report expected to be released later this month. Five sources familiar with the results of that study told CNN that US intelligence officials found no evidence that the UFOs are alien spacecraft, but investigators also have not reached a definitive assessment as to what these mysterious objects might be.

"We don't know if it's extraterrestrial. We don't know if it's an enemy. We don't know if it's an optical phenomenon," Nelson said. "We don't think [it's an optical phenomenon] because of the characteristics that those Navy jet pilots described ... And so the bottom line is, we want to know."

NASA’s Curiosity rover has captured images of clouds on Mars— as described in its blog post: “wispy puffs filled with ice crystals that scattered light from the setting sun, some of them shimmering with color.”

According to NASA clouds are rare in the thin atmosphere of Mars, but usually form at its equator during its coldest time of year. Scientists noticed that last year — two years ago in Earth time— there were clouds beginning to form earlier than expected, so this year they were ready.

If you use Alexa, Echo, or any other Amazon device, you have only 10 days to opt out of an experiment that leaves your personal privacy and security hanging in the balance.

On June 8, the merchant, Web host, and entertainment behemoth will automatically enroll the devices in Amazon Sidewalk. The new wireless mesh service will share a small slice of your Internet bandwidth with nearby neighbors who don’t have connectivity and help you to their bandwidth when you don’t have a connection.

By default, Amazon devices including Alexa, Echo, Ring, security cams, outdoor lights, motion sensors, and Tile trackers will enroll in the system. And since only a tiny fraction of people take the time to change default settings, that means millions of people will be co-opted into the program whether they know anything about it or not. The Amazon webpage linked above says Sidewalk "is currently only available in the US."

Microsoft said it is retiring Internet Explorer, the browser it created more than 25 years ago and which is now largely abandoned as people instead use competitors like Google's Chrome or Apple's Safari.

"We are announcing that the future of Internet Explorer on Windows 10 is in Microsoft Edge," the company said in a blog post Wednesday, referring to its other browser.

"Not only is Microsoft Edge a faster, more secure and more modern browsing experience than Internet Explorer, but it is also able to address a key concern: compatibility for older, legacy websites and applications," Microsoft said.

An explosive report featured on CBS News’s “60 Minutes” featured several former U.S. military officials who talked about what the U.S. government knows about unidentified aerial phenomena — UAP —more commonly referred to as UFOs.

The segment comes ahead of a report that the military is supposed to deliver an unclassified report to Congress by next month. Former Director of National Intelligence John Ratcliffe said in a recent interview that the findings will shock people because “frankly, there are a lot more sightings than have been made public.”

An experimental device that turns thoughts into text has allowed a man who was left paralyzed by an accident to construct sentences swiftly on a computer screen.

The man was able to type with 95% accuracy just by imagining he was handwriting letters on a sheet of paper, a team reported Wednesday in the journal Nature.

"What we found, surprisingly, is that [he] can type at about 90 characters per minute," says Krishna Shenoy of Stanford University and the Howard Hughes Medical Institute.

The device would be most useful to someone who could neither move nor speak, says Dr. Jaimie Henderson, a neurosurgeon at Stanford and co-director, with Shenoy, of the Stanford Neural Prosthetics Translational Laboratory.

Tesla CEO Elon Musk has changed his stance on cryptocurrency.

Back in March, Musk announced Tesla was accepting Bitcoin for its electric cars. Earlier this year the EV company even bought $1.5 billion of the cryptocurrency.

On Wednesday afternoon, that all ended. Musk tweeted that the cryptocurrency's "great cost to the environment" meant Tesla won't be offering the payment option for its zero-emissions vehicles.

The semiconductor industry's constant challenge is to make microchips that are smaller, faster, more powerful and more energy efficient — simultaneously.
On Thursday, IBM (IBM) announced it has created a 2-nanometer chip, the smallest, most powerful microchip yet developed.
Most computer chips powering devices today use 10-nanometer or 7-nanometer process technology, with some manufacturers producing 5-nanometer chips. The lower numbers denote smaller, more advanced processors. IBM's new chip uses 2-nanometer process technology, a huge leap forward for the components used to power everything from consumers' smart phones and appliances to supercomputers and transportation equipment.

"There are not many technologies or technological breakthroughs that end up lifting all boats," director of IBM Research Dario Gil said in an interview. "This is an example of one."

By shooting billions of lasers at the ground, scientists have uncovered evidence of a sophisticated civilization left by the ancient Maya who lived in the northern Yucatán Peninsula in what is now Mexico, a new study finds.

The laser survey revealed that in a region of the hilly northern Yucatán, known as the Puuc (pronounced "Pook"), the Maya built remarkable structures, including artificial reservoirs, more than 1,200 ovens, a handful of terraces for farming and nearly 8,000 platforms where houses were built. The ancient Maya also quarried the rock there, the laser scan revealed.

"It seems to have been a very prosperous area because we have all these masonry [stone] houses," study lead researcher William Ringle, a professor emeritus of anthropology at Davidson College in North Carolina, told Live Science. "It seems like people had access to what they needed."
