Most of the scribes who copied the text contained in the Dead Sea Scrolls were anonymous, as they neglected to sign their work. That has made it challenging for scholars to determine whether a given manuscript should be attributed to a single scribe or more than one, based on unique elements in their writing styles (a study called paleography). Now, a new handwriting analysis of the Great Isaiah Scroll, applying the tools of artificial intelligence, has revealed that the text was likely written by two scribes, mirroring one another's writing style, according to a new paper published in the journal PLOS ONE.

As we've reported previously, these ancient Hebrew texts—roughly 900 full and partial scrolls in all, stored in clay jars—were first discovered scattered in various caves near what was once the settlement of Qumran, just north of the Dead Sea, by Bedouin shepherds in 1946-1947. (Apparently, a shepherd threw a rock while searching for a lost member of his flock and accidentally shattered one of the clay jars, leading to the discovery.) Qumran was destroyed by the Romans, circa 73 CE, and historians believe the scrolls were hidden in the caves by a sect called the Essenes to protect them from being destroyed. The natural limestone and conditions within the caves helped preserve the scrolls for millennia; they date back to between the third century BCE and the first century CE.

Several of the parchments have been carbon dated, and synchrotron radiation—among other techniques—has been used to shed light on the properties of the ink used for the text. Most recently, in 2018, an Israeli scientist named Oren Ableman used an infrared microscope attached to a computer to identify and decipher Dead Sea Scroll fragments stored in a cigar box since the 1950s.

Of all the mysteries and injustices of the McDonald’s ice cream machine, the one that Jeremy O’Sullivan insists you understand first is its secret passcode.

Press the cone icon on the screen of the Taylor C602 digital ice cream machine, he explains, then tap the buttons that show a snowflake and a milkshake to set the digits on the screen to 5, then 2, then 3, then 1. After that precise series of no fewer than 16 button presses, a menu magically unlocks. Only with this cheat code can you access the machine’s vital signs: everything from the viscosity setting for its milk and sugar ingredients to the temperature of the glycol flowing through its heating element to the meanings of its many sphinxlike error messages.

“No one at McDonald’s or Taylor will explain why there’s a secret, undisclosed menu," O’Sullivan wrote in one of the first, cryptic text messages I received from him earlier this year.

On Wednesday, Cadillac formally revealed the production version of its next SUV. Called the Lyriq, when it goes on sale next year starting at $59,990, it will join the Hummer EV as part of General Motors' third wave of electric vehicles (after Chevrolet's experiments with the EV1 and Bolt EV).

If you think this vehicle looks familiar, you're right—in August 2020, Cadillac presented a show-car version of the Lyriq, and the production version has changed very little. But, at the time, Cadillac wasn't ready to talk technical specs. Now it is.

Propulsion to the rear wheels is provided by one of GM's Ultium Drive motors that will appear in more than 20 new EVs in the coming few years. That electric motor endows the Lyriq with 225 kW (340 hp) and 440 Nm (325 lb-ft), which should mean the 2,545 kg (5,610 lb) SUV will be appropriately quick as opposed to face-meltingly fast.

SpaceX has accused satellite-broadband rival OneWeb of spreading a false story claiming that the companies' satellites nearly crashed into each other.

In reality, "[t]he probability of collision never exceeded the threshold for a [collision-avoidance] maneuver, and the satellites would not have collided even if no maneuver had been conducted," SpaceX told the Federal Communications Commission in an ex parte filing. The filing describes a meeting that SpaceX and OneWeb representatives had with FCC staff yesterday in which SpaceX said it "corrected the record regarding recent press reports regarding physical coordination between SpaceX and OneWeb."

The meeting came one day after The Wall Street Journal published an article titled "Elon Musk's Satellite Internet Project Is Too Risky, Rivals Say." The Journal article described OneWeb's allegations as follows:

The US Senate Commerce Committee held a hearing for former Democratic Senator Bill Nelson on Wednesday to consider his nomination as NASA administrator. Nelson was warmly welcomed by his former colleagues—both Republicans and Democrats—who praised his wealth of experience in making space policy and said he was the best person for the job.

In response to these comments, Nelson thanked the senators and offered fairly bland remarks. “If you ask me what is my vision for the future of NASA, it is to continue for us to explore the heavens with humans and with machines," he said. "There is a lot of excitement."

There was not a lot of excitement during the hearing, however, aside from a handful of questions about a recent NASA award for the Human Landing System as part of the space agency's Artemis Moon Program.

In the world of social media, new networks are constantly popping into existence and then fading away when they fail to become the next Facebook (or Twitter, or TikTok, etc.). Still, last week's shutdown of the PS4's Communities features (and the lack of a suitable replacement on the PS5) has left many PlayStation fans bitter about the death of a vibrant space they used to connect with fellow gamers.

For those who never had a chance to join a PS4 Community, the groups served as a kind of player-created and moderated message board system, accessible directly via the PS4's system menu (and through the PlayStation Mobile app, before that connection was shut off last year). Members could share text messages, screenshots, wallpapers, and more on a shared "Community Wall" or form parties to chat and play multiplayer titles together with other online members.

Specific PS4 Communities could form around a single game or series, a geographic area, a cultural grouping, or just shared general interests ("Smoke&Play" and "Vaping Gamers" were popular Communities at one point).

Samsung on Wednesday kicked off something genuinely innovative in the smartphone market: an official consumer upcycling program. Samsung's "Galaxy Upcycling at Home" initiative was announced at CES 2021, and today it enters a "beta" release. The program allows users to transform old phones into smart home devices that work through Samsung's SmartThings app, which has two new modes: a sound sensor and a light sensor.

Samsung says the sound sensor mode will "accurately distinguish sounds in everyday surroundings, and users can choose to save certain sound recordings. For example, if the device detects sounds such as a baby crying, dog barking, cat meowing, or a knock, it will send an alert directly to the user’s smartphone, and the user can listen to the recorded sound." Samsung says the mode is meant to act as a baby monitor or pet care solution.

The Light Sensor mode simply turns your phone into a light sensor, allowing it to detect levels of sunlight or room light and trigger your smart home to do something in response. If you want to use this mode while on battery power, Samsung says it has "equipped the Galaxy Upcycling at Home upgrade with battery optimization solutions to minimize battery usage."

The real measure of success for Volkswagen's embrace of electric vehicles (EV) post-dieselgate will be how many the company can sell each year. But on Tuesday, VW's job might have gotten a little easier. That's because the new ID.4 crossover just won this year's World Car of the Year award, beating two other finalists, the adorable Honda E and the new Toyota Yaris. Fear not, E-fans: the diminutive electric hatchback won the World Urban Car category. Previous years' winners have included the Kia Telluride and the Jaguar I-Pace.

I expected the Honda E to win World Car Design of the Year; as one of the 93 jurors around the world, I gave it high marks because just look at it. But more of my fellow jurors picked the chunky Land Rover Defender for that honor, and the Rover also beat the Mazda MX-30 in the process.

The World Luxury Car award went to the new Mercedes-Benz S-Class, perhaps no surprise considering the other two finalists were the Defender and the Polestar 2. The Polestar is a fine EV with some very nifty tech, but it's no match for the bombastic Benz.
