As IT updates go, this was about as nerve-wracking as things can get.

In February, deep inside a warehouse at Cern, the Swiss home of the Large Hadron Collider (LHC) – the world’s biggest science experiment – two network engineers held their breath. And pressed a button.

Suddenly, text on a black background flashed up on a screen in front of them. It had worked. “There was high-fiving involved,” recalls Joachim Opdenakker at SURF, a Dutch IT association that works for educational and research institutions. “It was super-cool to see.”

He and his colleague Edwin Verheul had just set up a new data link between the LHC in Switzerland and data storage sites in The Netherlands.

A data link that could reach speeds of 800 gigabits per second (Gbps) – or more than 11,000 times the average UK home broadband speed. The idea is to improve scientists’ access to the results of LHC experiments.

A subsequent test in March using special equipment on loan from Nokia proved the desired speeds were achievable.

“This transponder that Nokia uses, it’s like a celebrity,” says Mr Verheul, explaining how the kit is booked up for use at various locations in advance. “We had limited time to do tests. If you have to postpone a week, then the transponder is gone.”

This amount of bandwidth, approaching one terabit per second, is extremely fast but some subsea cables are a few hundred times faster still – they use multiple fibre strands to achieve such speeds.

After its upgrade the Large Hadron Collider will produce five times as much data

In labs around the world, networking experts are coming up with fibre optic systems capable of pushing data around even more rapidly than this. They are reaching extraordinary speeds of many petabits per second (Pbps), or 300 million times the average UK home broadband connection.

This is so fast that one can barely imagine how people will use such bandwidth in the future. But engineers are wasting no time in proving that it is possible. And they only want to go faster.

The duplex cable (with cores that either send or receive) from Cern to data centres in The Netherlands is just shy of 1,650km (I,025 miles) long, snaking from Geneva to Paris, then Brussels, and finally Amsterdam. Part of the challenge in reaching 800 Gbps was in beaming pulses of light such a long way. “Due to the distance, the power levels of that light decrease, so you have to amplify it at different locations,” explains Mr Opdenakker.

Every time one tiny subatomic particle smashes into another during experiments at the LHC, the impact generates staggering volumes of data – about one petabyte per second. That’s enough to fill 220,000 DVDs.

This is slimmed down for storage and study, but still requires hefty amounts of bandwidth. Plus, with an upgrade due by 2029, the LHC expects to produce even more scientific data than it does today.

“The upgrade increases the number of collisions by at least a factor of five,” says James Watt, senior vice president and general manager of optical networks at Nokia.

A time when 800 Gbps seems slow may not be far away, however. In November, a team of researchers in Japan broke the world speed record for data transmission when they reached an astonishing 22.9 Pbps. That’s enough bandwidth to supply every single person on the planet, and then a couple billion more, with a Netflix stream, says Chigo Okonkwo at Eindhoven University of Technology, who was involved in the work.

In this case, a meaningless but huge stream of pseudorandom data was beamed over 13km of coiled fibre optic cable in a lab setting. Dr Okonkwo explains that the integrity of the data is analysed post-transfer to confirm it was sent as quickly as reported without accumulating too many errors.

He also adds that the system he and colleagues used relied on multiple cores – a total of 19 cores inside one fibre cable. This is a new type of cable unlike the standard ones that connect many people’s home to the internet.

More Technology of Business

But older fibre is expensive to dig up and replace. Extending its lifetime is useful, argues Wladek Forysiak at Aston University in the UK. He and colleagues have recently achieved speeds of around 402 terabits per second (Tbps) along a 50km-long optical fibre with just one core. That’s about 5.7 million times faster than the average UK home broadband connection.

“I think it’s a world best, we don’t know of any results that are better than that,” says Prof Forysiak. Their technique relies on using more wavelengths of light than usual when flashing data down an optical line.

For this they use alternative forms of the electronic equipment that sends and receives signals over fibre optic cables but such a setup could be easier to install than replacing thousands of kilometres of the cable itself.

Activities in the so-called metaverse might one day require extreme bandwidth, suggests Martin Creaner, director general of the World Broadband Association. His organisation expects home broadband connections to reach up to 50 Gbps by 2030.

But reliability may be even more important than speed for some applications. “For remote robotic surgery across 3,000 miles… you absolutely do not want any scenario where the network goes down,” says Mr Creaner.

Dr Okonkwo adds that training AI will increasingly require moving huge datasets around. The faster this can be done, the better, he argues.

And Ian Phillips, who works alongside Prof Forysiak, says bandwidth tends to find applications once it is available: “Humanity finds a way of consuming it.”

Demand for bandwidth is growing surprisingly fast says Lane Burdette

Although multiple petabits per second is far beyond what today’s web users need, Lane Burdette, research analyst at TeleGeography, a telecoms market research firm, says it is striking how quickly demand for bandwidth is growing – currently, at around 30% year-on-year on transatlantic fibre optic cables.

Content provision – social media, cloud services, video streaming – is eating up far more bandwidth than before, she notes: “It used to be like 15% of international bandwidth in the early 2010’s. Now it’s up to three quarters, 75%. It’s absolutely massive.”

In the UK, there is still a long way to go to improve internet speeds. Many people cannot access sufficiently fast broadband at home.

Andrew Kernahan, head of public affairs at the Internet Service Providers Association says most home users can now access gigabit per second speeds.

However, only about a third of broadband customers are signing up for such technology. There’s no “killer app” at the moment that really requires it, says Mr Kernahan. This might change as more and more TV is consumed via the internet, for example.

“There’s definitely a challenge to get the message out there and make people more aware of what they can do with the infrastructure,” he says.

How to watch Ariane 6 rocket’s maiden launch on Tuesday

Published

on



The European Space Agency (ESA) is about to conduct the maiden launch of its new Ariane 6 rocket. The new rocket builds on five decades of Ariane launches, and gives Europe a new spaceflight system for launching any type of satellite around Earth, to the moon, and beyond.

In the words of its operator, Arianespace, the new rocket will provide “new levels of efficiency and flexibility to meet customers’ evolving launch services needs across a full range of commercial and institutional missions.”

Arianespace is building two versions of the 63-meter-tall Ariane 6. Ariane 62 will fly with two strap-on boosters, while the more powerful Ariane 64 will fly with four.

Commenting on the upcoming launch, ESA said: “This is a big moment for Europe, as the rocket will ensure our guaranteed, autonomous access to space — and all of the science, Earth observation, technology development, and commercial possibilities that it entails. With many features brand new to Ariane 6, we’ll be able to carry more and take it further, while sustainably disposing of the launcher’s upper stage to prevent it becoming space debris.”

How to watch

Ariane 6 is scheduled to launch from Europe’s Spaceport in French Guiana on Tuesday, 9 July, with a four-hour launch window opening from 2 p.m. ET.

The launch will be streamed live on ESAWebTV and the broadcast will begin half an hour before liftoff. You can also watch it via ESA’s YouTube channel, which we’ve embedded at the top of this page.

What to expect

Ariane 6’s maiden flight will comprise three phases, each of which will demonstrate the various abilities of Europe’s newest heavy-lift rocket.

Phase one will include the launch and early stage of the flight, as well as the separation of the rocket’s main stage from the upper stage. It also involves the first boost of the upper stage’s Vinci engine to take it into an elliptical orbit above Earth.

The second phase will put Ariane 6’s newest feature to the test — reignition of the upper stage to change Ariane 6’s orbit from elliptical to a circular orbit. It will then deploy three satellites — OOV-Cube, Curium One and Robusta-3A — and activate of two onboard experiments, YPSat and Peregrinus.

A few seconds later, the second batch of satellites will deploy — 3Cat-4, ISTSat, and GRBBeta. The last two experiments will also be activated, SIDLOC and Parisat. A third separation command will then deploy CURIE and replicator.

The final phase will push the rocket’s cryogenic upper stage to its limit to validate its ability to perform in microgravity conditions. Two reentry capsules will also separate from the upper stage and descend to Earth by surviving a fiery re-entry through the atmosphere.

With the mission complete, the upper stage will burn up in Earth’s atmosphere to avoid becoming another piece of hazardous space junk.

As the E.V. Revolution Slows, Ferrari Enters the Race

Published

on


Gliding on robotic haulers, a line of Ferrari frames maneuvers through a gleaming new factory in Northern Italy. At each station, engineers in cherry red uniforms add a component — an engine block, a dashboard, a steering wheel — as they transform the bodies into hybrid vehicles. Up next: fully electric.

A lot is riding on Ferrari’s 200-million-euro “e-building,” which went into operation last month and is nearly twice the size of Rome’s Colosseum. The factory is intended to bring the 77-year-old sports-car maker, known for the sonorous vroom of its gas engines, into the age of electrification.

But the effort comes at a precarious time for the auto industry. The transition to electric vehicles, which was supposed to quickly usher in an era of climate-friendly transport, has instead been squeezed by costly investments and slowing global demand.

Other luxury carmakers have struggled to go electric. Mercedes-Benz and Lamborghini have reduced their ambitions. Tesla reported declining second-quarter sales on Tuesday, and Ford Motor said in April that it would shift production to more hybrids as E.V. losses piled up. A growing trade war between China and the West also threatens to stifle growth.

Despite the challenges, Ferrari sees an opportunity in the industry’s inevitable march toward electrification to reach a new consumer: the wealthy environmentalist. It intends to unveil its first fully electric model in the fourth quarter of next year. As part of its strategy, the carmaker has enlisted LoveFrom — the agency founded by Jony Ive, Apple’s former design chief, and the industrial designer Marc Newson — to hone the car’s appearance.

There is plenty of mystery shrouding the yet-to-be-named car, including its battery life and what it will sound like. The company has not disclosed its look, production run or price tag. But it could be one of the most expensive electric vehicles on the market, analyst say, surpassing Porsche’s $286,000 Taycan Turbo GT.

Ferrari’s foray into electric will be notable for other reasons. Regulators may be pushing electric vehicles, but there is lingering skepticism in the marketplace. Winning over fans of combustion engines will not be easy — even for Ferrari. And the industry is desperate for an automaker, any automaker, to prove that electric vehicles can drive big profits.

“It’s worth watching whether a Ferrari E.V. can maintain the kind of price premium you’d associate with a Ferrari,” said Martino de Ambroggi, an automotive analyst at Equita, an investment bank in Milan. “Often, a Ferrari purchase is also viewed as a kind of investment. Only after a few years will we see if that investment in an electric Ferrari holds up.”

Benedetto Vigna, Ferrari’s chief executive, is doing his best to keep the market in anticipation. In an interview last month in the new plant, he said the company would commence full-scale electric vehicle production by early 2026. By 2030, electric and hybrid cars will make up as much as 80 percent of Ferrari’s annual output as the company seeks to meet stringent European Union emissions mandates.

In the meantime, the e-building will roll out two models: the SF90 Stradale, a plug-in hybrid, and the combustion engine Purosangue.

Ferrari does not need an electric vehicle to pad its bottom line. Under Mr. Vigna, a former executive at the chip maker STMicroelectronics who took the helm nearly three years ago, the company has been on a tear. The stock is one of the best performers in Europe this year, giving it a roughly $75 billion market valuation, higher than that of Ford or General Motors. Profits are soaring alongside prices at Ferrari, which makes some of the most expensive cars on the planet. There’s a three-year waiting list for some models.

Ferrari’s success over the years on the Formula 1 track has also led to a lucrative corporate sponsorship and merchandise business that has transformed it into a luxury brand with a sporty flair. Ferrari’s prancing horse logo can be found on high-end apparel like a €790 cashmere sweater.

Mr. Vigna sees the electric vehicle as part of the company’s growth strategy, despite the industry’s slowdown. “There are some potential clients, I have them clearly in mind, who will never become part of the family unless there is an electric car,” he said.

But challenges loom. Enthusiasts who had gathered outside the factory gates last month wondered: Will it look, handle and sound like the classic Ferrari growler, or have the understated whine of most electric vehicles?

“When you think of a Ferrari, it still has that kind of engine sensation, and you also think of the roar,” Mr. de Ambroggi said. “I don’t know how Ferrari resolves this.”

Mr. Vigna fields that question often, especially from longtime customers, or Ferraristi. They seem to be channeling the deceased founder, Enzo Ferrari, who once broke down in the simplest terms how he built some of the fastest cars on the planet: “I build motors and attach them to wheels.”

Mr. Vigna’s E.V. pitch has a different ring. “The electric engine will not be silent,” he said. “There are ways to make sure that the emotion comes through from driving an electric Ferrari that is the same as when you drive a hybrid or when you drive a thermal Ferrari.”

Battery life is another puzzle piece. Because Ferraris often sell for a higher price on the secondary market, the concern about battery degradation, and its impact on the long-term value of the car, may be felt more acutely by the Ferraristi.

“The E.V. transition raises a whole lot of new issues for them in terms of how you maintain the vehicle,” said Stephen Reitman, an auto analyst at Bernstein.

Ferrari’s longtime partner, SK On, a South Korean battery maker, will supply the components for the E.V. batteries, which Ferrari will assemble in the e-building, where it will also make the car’s electric motors and axles.

And then there is the matter of price. Last month, Reuters reported that the car would cost at least €500,000 ($540,000). Mr. Vigna pushed back on the speculation, saying it is too early to talk price.

Ferrari still follows its founder’s principle for producing a limited number of extremely expensive cars. Ferrari made fewer than 14,000 last year; even with the e-building, production is not expected to increase much at the start.

The limited numbers may explain why fans make the pilgrimage to Maranello hoping to catch a glimpse of a Ferrari, either on the company’s Formula 1 test track or near its red brick factory.

Knowing demand is high, Mr. Vigna has increased the base price of most models more than 25 percent.

“Ferrari consistently sells less than the market demands, leading to a multiyear order book,” said Mr. Reitman, the Bernstein analyst. With a profit margin of nearly 30 percent, Ferrari’s business more resembles that of a luxury brand like Hermes or Rolex, analysts say.

Mr. Vigna is already thinking about how to market the new electric car. The target customer probably will not be buying the car for purely practical or even planet-saving reasons, he said, adding: “The emotional part of the brain is driving the purchase.”

Students Target Teachers in Group TikTok Attack, Shaking Their School

Published

on


In February, Patrice Motz, a veteran Spanish teacher at Great Valley Middle School in Malvern, Pa., was warned by another teacher that trouble was brewing.

Some eighth graders at her public school had set up fake TikTok accounts impersonating teachers. Ms. Motz, who had never used TikTok, created an account.

She found a fake profile for @patrice.motz, which had posted a real photo of her at the beach with her husband and their young children. “Do you like to touch kids?” a text in Spanish over the family vacation photo asked. “Answer: Sí.”

In the days that followed, some 20 educators — about one quarter of the school’s faculty — discovered they were victims of fake teacher accounts rife with pedophilia innuendo, racist memes, homophobia and made-up sexual hookups among teachers. Hundreds of students soon viewed, followed or commented on the fraudulent accounts.

In the aftermath, the school district briefly suspended several students, teachers said. The principal during one lunch period chastised the eighth-grade class for its behavior.

The biggest fallout has been for teachers like Ms. Motz, who said she felt “kicked in the stomach” that students would so casually savage teachers’ families. The online harassment has left some teachers worried that social media platforms are helping to stunt the growth of empathy in students. Some teachers are now hesitant to call out pupils who act up in class. Others said it had been challenging to keep teaching.

“It was so deflating,” said Ms. Motz, who has taught at the school, in a wealthy Philadelphia suburb, for 14 years. “I can’t believe I still get up and do this every day.”

The Great Valley incident is the first known group TikTok attack of its kind by middle schoolers on their teachers in the United States. It’s a significant escalation in how middle and high school students impersonate, troll and harass educators on social media. Before this year, students largely impersonated one teacher or principal at a time.

The middle schoolers’ attack also reflects broader concerns in schools about how students’ use, and abuse, of popular online tools is intruding on the classroom. Some states and districts have recently restricted or banned student cellphone use in schools, in part to limit peer harassment and cyberbullying on Instagram, Snap, TikTok and other apps.

Now social media has helped normalize anonymous aggressive posts and memes, leading some children to weaponize them against adults.

“We didn’t have to deal with teacher-targeting at this scale before,” said Becky Pringle, president of the National Education Association, the largest U.S. teachers’ union. “It’s not only demoralizing. It could push educators to question, ‘Why would I continue in this profession if students are doing this?’”

In a statement, the Great Valley School District said it had taken steps to address “22 fictitious TikTok accounts” impersonating teachers at the middle school. It described the incident as “a gross misuse of social media that profoundly impacted our staff.”

Last month, two female students at the school publicly posted an “apology” video on a TikTok account using the name of a seventh-grade teacher as a handle. The pair, who did not disclose their names, described the impostor videos as a joke and said teachers had blown the situation out of proportion.

“We never meant for it to get this far, obviously,” one of the students said in the video. “I never wanted to get suspended.”

“Move on. Learn to joke,” the other student said about a teacher. “I am 13 years old,” she added, using an expletive for emphasis, “and you’re like 40 going on 50.”

In an email to The New York Times, one of the students said that the fake teacher accounts were intended as obvious jokes, but that some students had taken the impersonations too far.

A TikTok spokeswoman said the platform’s guidelines prohibit misleading behavior, including accounts that pose as real people without disclosing that they are parodies or fan accounts. TikTok said a U.S.-based security team validated ID information — such as driver’s licenses — in impersonation cases and then deleted the data.

Great Valley Middle School, known locally as a close-knit community, serves about 1,100 students in a modern brick complex surrounded by a sea of bright green sports fields.

The impostor TikToks disrupted the school’s equilibrium, according to interviews with seven Great Valley teachers, four of whom requested anonymity for privacy reasons. Some teachers already used Instagram or Facebook but not TikTok.

The morning after Ms. Motz, the Spanish teacher, discovered her impersonator, the disparaging TikToks were already an open secret among students.

“There was this undercurrent conversation throughout the hallway,” said Shawn Whitelock, a longtime social studies teacher. “I noticed a group of students holding a cellphone up in front of a teacher and saying, ‘TikTok.’”

Students took images from the school’s website, copied family photos that teachers had posted in their classrooms and found others online. They made memes by cropping, cutting and pasting photos, then superimposing text.

The low-tech “cheapfake” images differ from recent incidents in schools where students used artificial intelligence apps to generate real-looking, digitally altered images known as “deepfakes.”

While some of the Great Valley teacher impostor posts seemed jokey and benign — like “Memorize your states, students!” — other posts were sexualized. One fake teacher account posted a collaged photo with the heads of two male teachers pasted onto a man and woman partially naked in bed.

Fake teacher accounts also followed and hit on other fake teachers.

“It very much became a distraction,” Bettina Scibilia, an eighth-grade English teacher who has worked at the school for 19 years, said of the TikToks.

Students also targeted Mr. Whitelock, who was the faculty adviser for the school’s student council for years.

A fake @shawn.whitelock account posted a photo of Mr. Whitelock standing in a church during his wedding, with his wife mostly cropped out. The caption named a member of the school’s student council, implying the teacher had wed him instead. “I’m gonna touch you,” the impostor later commented.

I spent 27 years building a reputation as a teacher who is dedicated to the profession of teaching,” Mr. Whitelock said in an interview. “An impersonator assassinated my character — and slandered me and my family in the process.”

Mrs. Scibilia said a student had already posted a graphic death threat against her on TikTok earlier in the school year, which she reported to the police. The teacher impersonations increased her concern.

“Many of my students spend hours and hours and hours on TikTok, and I think it’s just desensitized them to the fact that we’re real people,” she said. “They didn’t feel what a violation this was to create these accounts and impersonate us and mock our children and mock what we love.”

A few days after learning of the videos, Edward Souders, the principal of Great Valley Middle School, emailed the parents of eighth graders, describing the impostor accounts as portraying “our teachers in a disrespectful manner.”

In early March, the principal of Great Valley Middle School, Edward Souders, sent eighth-grade parents an email about the impostor accounts on TikTok.

The school also held an eighth-grade assembly on responsible technology use.

But the school district said it had limited options to respond. Courts generally protect students’ rights to off-campus free speech, including parodying or disparaging educators online — unless the students’ posts threaten others or disrupt school.

“While we wish we could do more to hold students accountable, we are legally limited in what action we can take when students communicate off campus during nonschool hours on personal devices,” Daniel Goffredo, the district’s superintendent, said in a statement.

The district said it couldn’t comment on any disciplinary actions, to protect student privacy.

In mid-March, Nikki Salvatico, president of the Great Valley Education Association, a teachers’ union, warned the school board that the TikToks were disrupting the school’s “safe educational environment.”

“We need the message that this type of behavior is unacceptable,” Ms. Salvatico said at a school board meeting on March 18.

The next day, Dr. Souders sent another email to parents. Some posts contained “offensive content,” he wrote, adding: “I am optimistic that by addressing it together, we can prevent it from happening again.”

In mid-March, Dr. Souders, the principal, sent a second email to parents, this time noting that some of the TikToks contained “offensive content.”

While a few accounts disappeared — including those using the names of Ms. Motz, Mr. Whitelock and Mrs. Scibilia — others popped up. In May, a second TikTok account impersonating Mrs. Scibilia posted several new videos mocking her.

She and other Great Valley educators said they had reported the impostor accounts to TikTok, but had not heard back. But several teachers, who felt the videos had violated their privacy, said they did not provide TikTok with a personal ID to verify their identities.

On Wednesday, TikTok removed the account impersonating Mrs. Scibilia and three other fake Great Valley teacher accounts flagged by a reporter.

Mrs. Scibilia and other teachers are still processing the incident. Some teachers have stopped posing for and posting photographs, lest students misuse the images. Experts said this type of abuse could harm teachers’ mental health and reputations.

“That would be traumatizing to anyone,” said Susan D. McMahon, a psychology professor at DePaul University in Chicago and chair of the American Psychological Association’s Task Force on Violence Against Educators. She added that verbal student aggression against teachers was increasing.

Now teachers like Mrs. Scibilia and Ms. Motz are pushing schools to educate students on how to use tech responsibly — and bolster policies to better protect teachers.

In the Great Valley students’ “apology” on TikTok last month, the two girls said they planned to post new videos. This time, they said, they would make the posts private so teachers couldn’t find them.

“We’re back, and we’ll be posting again,” one said. “And we are going to private all the videos at the beginning of next school year,” she added, “’cause then they can’t do anything.”

On Friday, after a Times reporter asked the school district to notify parents about this article, the students deleted the “apology” video and removed the teacher’s handle from their account. They also added a disclaimer: “Guys, we’re not acting as our teachers anymore that’s in the past !!”
