Britain's Defence Science and Technology Laboratory has developed a quantum atomic clock that will lose less than one second over billions of years, the Ministry of Defence announced on Thursday.

The UK-built device aims to reduce military reliance on GPS technology, which can be disrupted by adversaries. It will be deployable in military operations within five years, supporting navigation systems, encrypted communications, and advanced weapons systems. The $34.6 million project involves partners including Infleqtion UK, Aquark Technologies, and Imperial College London. The clock was tested outside laboratory conditions for the first time in collaboration with the Royal Navy and Army Futures team.

An anonymous reader quotes a report from The Guardian: When the scientist and inventor Prof Archibald Montgomery Low predicted "a day in the life of a man of the future" one century ago, his prophecies were sometimes dismissed as "ruthlessly imaginative." They included, reported the London Daily News in 1925, "such horrors" as being woken by radio alarm clock; communications "by personal radio set"; breakfasting "with loudspeaker news and television glimpses of events"; shopping by moving stairways and moving pavements. One hundred years after Low's publication of his book The Future some of his forecasts were spot on. Others, including his prophecy that everyone would be wearing synthetic felt one-piece suits and hats, less so.

Researchers from the online genealogy service Findmypast, have excavated accounts of Low's predictions from its extensive digital archive of historical newspapers available to the public and included them in a collection on its website of forecasts made for 2025 by people a century ago. Low, born in 1888, was an engineer, research physicist, inventor and author. A pioneer in many fields, he invented the first powered drone, worked on the development of television, was known as the "father of radio guidance systems" for his work on planes, torpedo boats and guided rockets and reportedly attracted at least two unsuccessful assassination attempts by the Germans. "It's amazing that a century ago, one visionary scientist could predict how emerging technology -- in its infancy at the time -- could have changed the world by 2025," said Jen Baldwin, a research specialist at Findmypast. "It makes you stop to wonder how the advancements we see around us today will be experienced by our own descendants."

Traditional airlines worldwide are rapidly eliminating long-standing perks from their basic fares, blurring the line between full-service and budget carriers, according to industry analysis of 90 major airlines.

Air Canada's decision to ban standard carry-on luggage for its lowest-fare passengers from January 3 marks the latest rollback, joining United Airlines, Finnair, and others. Most legacy carriers, including British Airways, Air France, and Lufthansa, have already stripped checked baggage and seat selection from basic fares, signaling an industry-wide shift toward budget airline practices.

Traditional barcodes are set to be replaced by next-generation QR-style codes by 2027, offering enhanced functionality such as embedding sell-by dates, allergens, and recycling information. The Guardian reports: Tesco has started using them on some products, and other trials have suggested that waste of perishable food such as poultry can be cut by embedding sell-by dates in the new QR-style codes, allowing for more dynamic discounting. QR (quick response) codes will allow customers to instantly access more information about the product, including how to recycle batteries, clothes and building materials when tougher environmental regulations bite. But they will also put a greater demand on the world's cloud computing resources, where the extra data they contain will be stored -- meaning a potentially greater carbon footprint.

The first barcode was read in an Ohio supermarket in June 1974 when a packet of Juicy Fruit chewing gum was rung up. It was devised by Joe Woodland, an inventor who had been implored by a retailer frustrated at losing profits, to speed up checkout queues and stocktaking. Coca-Cola has used the new generation of codes in parts of Latin America for refillable bottles, with the QR code allowing the counting of refills so that a requirement of 25 before recycling can be enforced. The Australian supermarket chain Woolworths is said to have reduced food waste by up to 40% in some areas, as the codes allow stores to better spot products approaching expiry and discount more efficiently. "We've defined an ambition that by the end of 2027 all retailers in the world will be able to read those next-generation barcodes," said Renaud de Barbuat, the president and chief executive of GS1. "We think it's doable ... It represents some investment on the part of retailers to adapt their point-of-sale systems, but it's already well under way."

Anne Godfrey, the chief executive of GS1 UK, said: "This has been in the works for some time, but Covid really accelerated it. During the pandemic, everyone got used to pointing their phones at QR codes in pubs and restaurants to access the menu."

Long-time Slashdot reader schwit1 writes: The Dubai-based startup LEAP71, focused on using AI software to quickly develop rocket engine designs it can then 3D print, has successfully test fired a prototype aerospike engine on December 18, 2024 during a static fire test campaign conducted in the United Kingdom.
Along the way they tackled a problem with bell-shaped rocket nozzles, writes New Atlas. "A rocket that works very well on liftoff will work less well as it rises in the atmosphere and the air pressure decreases. This is why second- and third-stage rocket engines are different from those of the first stage." Ideally, engineers want an engine that can adjust itself automatically to changes in air pressure. An aerospike does this by shaping the engine into a spike or plug with a curve like that of the inside of a rocket bell. As the combustion gases flow from the engine over the spike, the curve acts as one side of the bell and the surrounding air as the outside curve. As the air pressure changes, so does the shape of the virtual bell. There have been a number of aerospike engines developed since the 1950s and one has actually gone airborne, but there's still a long way to go when it comes to turning a promising idea into a practical space engine.

LEAP 71's contribution to the effort is to apply its Noyron Large Computational Engineering Model to the problem. It's an AI programmed and trained by aerospace experts to take a given set of input parameters and use them to create a design that meets those parameters by inferring physical interactions of various factors, including thermal behaviors and projected performance. The results of this are then fed back into the AI model to fine tune it as it presents computed performance parameters, the geometry of the engine, the parameters of the manufacturing process, and other details.
"Despite their clear advantages, Aerospikes are not used in space access today," LEAP 71's co-founder said in a statement. "We want to change that. Noyron allows us to radically cut the time we need to re-engineer and iterate after a test and enables us to converge rapidly on an optimal design."

Aerospikes "are more compact and significantly more efficient across various atmospheric pressures, including the vacuum of space," the company said this week — announcing the successful hot-firing of their Aerospike engine, and calling it "one of the most advanced and elusive rocket engines ever created..." By leveraging the power of Noyron's computational AI, the thruster was developed in a matter of weeks, manufactured as a monolithic piece of copper through industrial 3D printing, and put on the test stand, where it worked successfully on the first attempt...

The Aerospike was fired on December 18th, 2024, as part of a four-engines-in-four-days campaign conducted by LEAPâ71 at Airborne Engineering in Westcott, UK. The company will process the collected data to fine-tune Noyron for the next iteration of engines and continue testing in 2025, with the goal of making Aerospikes a viable option for modern spacecraft.

Slashdot reader DevNull127 writes: This year the London Stock Exchange got a new listing for "Raspberry Pi Holdings plc." It's the computer-making commercial subsidiary of their larger educational charity, the Raspberry Pi Foundation. "Access to the public market will enable us to build more of the products you love, faster," explained CEO Eben Upton in June. And in May Foundation head Philip Colligan added that beyond the $50 million already donated to their educational charity by the commercial subsidiary, the IPO would allow the conversion of some stock sales to "an endowment that we will use to fund our educational programmes... The Foundation will use any funds that we raise through the sale of shares at the IPO — or subsequently — to advance our ambitious global strategy to enable every young person to realise their full potential through the power of computing and digital technologies."

So how's that working out? A finance site called Proactive Investors UK reports that in September Raspbery Pi Holdings plc "reported underlying profits (EBITDA) of US$20.9 million, up by 55% from a year ago, on revenues up 61% to US$144 million... The Pi 5 single-board computer (SBC), launched at the end of last October [2023], sold 1.1 million units in the first half, with overall unit growth at 31%."

And then in December its stock price suddenly shot up to more than double where it was at the end of November — giving Raspbery Pi Holdings plc a valuation "just under £1.3 billion."

Facial recognition technology is poised to replace traditional passports globally, marking the biggest shift in travel documentation since World War 1. Airports across Finland, Canada, Netherlands, UAE, UK, Italy, US, and India are testing passport-free systems, with Singapore already implementing the technology for its residents and departing visitors.

The systems typically store passport data digitally on smartphones, using face recognition cameras at airports to match travelers against stored photos. Singapore officials report over 1.5 million people have used their system, while Finnish trials showed identity checks taking just eight seconds.

The UK's Information Commissioner's Office (ICO) warns that while most adults recognize the importance of wiping personal data from old devices, nearly 30% don't know how, and a significant number of young people either don't care or find it too cumbersome. The Register reports: Clearing personal data off an old device is an important step before ditching it or handing it on to another user. However, almost three in ten (29 percent) of adults don't know how to remove the information, according to a survey of 2,170 members of the UK public. Seventy-one percent agreed that wiping a device was important, but almost a quarter (24 percent) reckoned it was too arduous. This means that the drawer of dusty devices is set to swell -- three-quarters of respondents reported hanging on to at least one old device, and a fifth did so because they were worried about their personal information. [...]

More than one in five (21 percent) of young people in the survey didn't think it was important to wipe personal data, while 23 percent said they didn't care about what might happen to that data. Fourteen percent of people aged 18-34 said they wouldn't bother wiping their devices at all, compared to just 4 percent of people over 55. On the plus side, the majority (84 percent) of respondents said they would ensure data was erased before disposing of a device. Alternatively, some might not worry about it and stick it in that special drawer alongside all the cables that might be needed one day. The survey also found that more than a quarter (27 percent) of UK adults were planning to treat themselves to a new device over the festive season [...].

The UK Post Office has appointed Paul Anastassi as interim CTO amid efforts to replace its controversial Horizon IT system, which led to hundreds of wrongful convictions of subpostmasters due to software errors since 1999.

The appointment, the news of which an anonymous reader shared, comes as the Post Office grapples with its $1.25 billion over-budget New Branch IT project, which was recently paused after being deemed "unachievable" in a government report. The organization is reportedly considering purchasing the Horizon system from Fujitsu while combining it with in-house and commercial software solutions.

Research finds people who have more than four coffees a day have 17% lower chance of head and neck cancers. From a report: If the only thing getting you through a mountain of present-wrapping is a mug of tea or coffee, be of good cheer. Researchers have found people who consume those drinks have a slightly lower risk of head and neck cancers. There are about 12,800 new head and neck cancer cases and about 4,100 related deaths in the UK every year, according to Cancer Research UK.

The new study does not prove that tea and coffee are themselves protective against such cancers, but experts say the findings help to shed light on what has been a much debated area with inconsistent results. "While there has been prior research on coffee and tea consumption and reduced risk of cancer, this study highlighted their varying effects with different sub-sites of head and neck cancer including the observation that even decaffeinated coffee had some positive impact," said Dr Yuan-Chin Amy Lee of Huntsman Cancer Institute and the University of Utah School of Medicine, the senior author of the study.

Writing in the journal Cancer, the team report how they analysed data from 14 studies that covered Europe, North America and Latin America. [...] After taking into account factors such as age, sex, daily number of cigarettes smoked, alcohol consumption and fruit and vegetable consumption, the researchers found that people who drink more than four cups of caffeinated coffee a day have a 17% lower chance of developing head and neck cancers overall compared with those who do not drink the beverage. Specifically they found such consumption was associated with reduced odds of cancers of the oral cavity and the oropharynx -- part of the throat just behind the mouth.

Saturday France connected a new nuclear reactor to its grid "for the first time in a quarter century..." reports Bloomberg, "adding low-carbon electricity supply at a time when a sputtering economy has made demand sluggish." The Flamanville-3 reactor — the first such addition since Civaux 2 was connected in 1999 — will join EDF's fleet of 56 reactors in France, which generate more than two-thirds of the country's electricity and are the backbone of western Europe's power system. When fully ramped up, the new unit will provide a stable source of supply, which can be particularly useful during peak hours in the winter. Increased nuclear output will also curb the use of gas-fired power stations.

France is set for record power exports in 2024 as local demand remains subdued and it keeps adding renewable capacity. Better generation from EDF's nuclear fleet is also helping keep a lid on wholesale prices, partly reversing bill increases caused by Europe's energy crisis. The Flamanville-3 reactor in the country's northwest adds 1.6 gigawatts of output, raising France overall atomic capacity to about 63 gigawatts...

Since construction started in 2007, its budget — excluding finance costs — has quadrupled to an estimated €13.2 billion ($13.9 billion). The yearslong saga has created lasting doubts about the French nuclear industry's ability to build reactors on time and on schedule — a crucial issue as it prepares to build at least six large plants in the country. EDF's ongoing work on two similar reactors in the UK has also suffered repeated delays and cost overruns, complicating the British government's effort to raise funds for the construction of another pair of EPRs.

Long-time Slashdot AmiMoJo quotes this report from EcoWatch: Record wind-generated electricity across Northern Ireland and Scotland Tuesday night pushed Britain's power prices below zero.

Wind output peaked at a record high 22.4 gigawatts (GW), breaking the previous high set [last] Sunday evening, the national system operator said, as Bloomberg reported. The record output provided more than 68 percent of the country's power.

From 5:30 to 6:30 a.m. on Wednesday, the half-hourly price fell to 6.57 pounds per megawatt-hour, according to data from European power exchange Epex Spot.

"Setting another clean electricity generation record just four days after the previous high shows the pivotal role wind is playing in keeping the country powered up during the festive season," said Dan McGrail, chief executive of RenewableUK, as . "This is also demonstrated by today's official figures which reveal that renewables have generated more than half our electricity for four quarters in a row."
The article adds that energy prices with negative numbers "have been recorded for 131 hours in the UK this year, an increase of 45 hours over 2023...

"Wind power was the largest source of energy in the UK from January to September of 2024."

The world's first nuclear-powered battery — a diamond with an embedded radioactive isotope — could power small devices for thousands of years, according to scientists at the UK's University of Bristol.

Long-time Slashdot reader fahrbot-bot shared this report from LiveScience: The diamond battery harvests fast-moving electrons excited by radiation, similar to how solar power uses photovoltaic cells to convert photons into electricity, the scientists said.

Scientists from the same university first demonstrated a prototype diamond battery — which used nickel-63 as the radioactive source — in 2017. In the new project, the team developed a battery made of carbon-14 radioactive isotopes embedded in manufactured diamonds. The researchers chose carbon-14 as the source material because it emits short-range radiation, which is quickly absorbed by any solid material — meaning there are no concerns about harm from the radiation. Although carbon-14 would be dangerous to ingest or touch with bare hands, the diamond that holds it prevents any short-range radiation from escaping. "Diamond is the hardest substance known to man; there is literally nothing we could use that could offer more protection," Neil Fox, a professor of materials for energy at the University of Bristol, said in the statement...

A single nuclear-diamond battery containing 0.04 ounce (1 gram) of carbon-14 could deliver 15 joules of electricity per day. For comparison, a standard alkaline AA battery, which weighs about 0.7 ounces (20 grams), has an energy-storage rating of 700 joules per gram. It delivers more power than the nuclear-diamond battery would in the short term, but it would be exhausted within 24 hours. By contrast, the half-life of carbon-14 is 5,730 years, which means the battery would take that long to be depleted to 50% power....

[A] spacecraft powered by a carbon-14 diamond battery would reach Alpha Centauri — our nearest stellar neighbor, which is about 4.4 light-years from Earth — long before its power were significantly depleted.
The battery has no moving parts, according to the article. It "requires no maintenance, nor does it have any carbon emissions."

Craig Wright, an Australian computer scientist living in the UK, has been found guilty of contempt of court for persistently and falsely claiming to be Bitcoin's creator, Satoshi Nakamoto, despite a High Court ruling against his claim. He has been sentenced to 12 months in prison, suspended for two years, and faces jail if he continues his assertions. The BBC reports: [...] Wright, who appeared via videolink, refused to disclose where he was, saying only he was in Asia. It means an international arrest warrant would have to be issued if the UK authorities wanted to detain him.

Wright's actions were described in court as "legal terrorism" that "put people through personal hell" in his campaign to be recognised as Bitcoin's inventor. The judge, Mr Justice Mellor, said Wright arguments were "legal nonsense" but acknowledged that he was not in the UK and "appears to be well aware of countries with which the UK does not have extradition arrangements".

Writers, publishers, musicians, photographers, movie producers and newspapers have rejected the Labour government's plan to create a copyright exemption to help AI companies train their algorithms. From a report: In a joint statement, bodies representing thousands of creatives dismissed the proposal made by ministers on Tuesday that would allow companies such as Open AI, Google and Meta to train their AI systems on published works unless their owners actively opt out.

The Creative Rights in AI Coalition (Crac) said existing copyright laws must be respected and enforced rather than degraded. The coalition includes the British Phonographic Industry, the Independent Society of Musicians, the Motion Picture Association and the Society of Authors as well as Mumsnet, the Guardian, Financial Times, Telegraph, Getty Images, the Daily Mail Group and Newsquest.

Their intervention comes a day after the technology and culture minister Chris Bryant told parliament the proposed system, subject to a 10-week consultation, would "improve access to content by AI developers, whilst allowing rights holders to control how their content is used for AI training."

Spanish police have uncovered a major clue in the year-long investigation of a missing Cuban man, JLPO, after Google Street View images showed a man loading a body-shaped package into a car and pushing a wheelbarrow with a large white package. These images led to the discovery of the victim's dismembered remains in a cemetery and the arrest of two suspects, including the victim's wife and a bar worker. The Independent reports: Spanish police have said the pictures are a "decisive" clue in case, with detectives reportedly launching a murder investigation and arresting two people in connection with the man's death. According to El Pais, police are still investigating the case -- and it appears neither have yet appeared charged before a court.

An anonymous reader quotes a report from The Guardian: The UK's first driverless bus service, originally heralded as a breakthrough of global significance, is being withdrawn from service because too few passengers used it. The autonomous buses, operated by Stagecoach, have been running between Fife and Edinburgh along a 14-mile route over the Forth road bridge since May 2023 to relieve the heavy congestion which can bring traffic to a standstill.

The CAVForth service, a collaboration between Fusion Processing, the coach-building company Alexander Dennis, Napier University in Edinburgh and the Bristol Robotics Lab -- a joint venture between the University of Bristol and the University of the West of England -- was touted as the most ambitious and complex in the world. Built at an estimated cost of more than 6 million pounds, partly funded by the UK government, the fleet of five single-decker buses had the capacity to carry 10,000 passengers a week but needed two crew on board for safety reasons. Stagecoach said in a statement: "We are proud to have achieved a world first with our CAVForth autonomous bus service, demonstrating the potential for self-driving technology on a real-world registered timetable in East Scotland. Although passenger adoption did not meet expectations, the trial has significantly advanced the understanding of the operational and regulatory requirements for autonomous services, delivering what was expected from this demonstrator project. The partners remain committed to exploring new opportunities for self-driving technology in other areas across the UK, ensuring that this exciting innovation can play a transformative role in future transport networks."

Hundreds of websites will be shut down on the day that Britain's Online Safety Act comes into effect, in what are believed to be the first casualties of the new internet laws. From a report: Microcosm, a web forum hosting service that runs 300 sites including cycling forums and local community hubs, said that the sites would go offline on March 16, the day that Ofcom starts enforcing the Act.

Its owner said they were unable to comply with the lengthy requirements of the Act, which created a "disproportionately high personal liability." The new laws, which were designed to crack down on illegal content and protect children, threaten fines of at least $23 million for sites that fail to comply with the laws. On Monday, Ofcom set out more than 40 measures that it expects online services to follow by March, such as carrying out risk assessments about their sites and naming senior people accountable for ensuring safety.

An anonymous reader shares a report: A Chinese hacker indicted earlier this month and the PRC-based cybersecurity company he worked for are both sanctioned by the US government for compromising "tens of thousands of firewalls" -- some protecting US critical infrastructure, putting human lives at risk.

In a series of coordinated actions, the US Treasury Department's Office of Foreign Assets Control (OFAC), the Department of Justice (DoJ), and the FBI said the massive cyber espionage campaign, which compromised at least 36 firewalls protecting US critical infrastructure, posed significant risks to national security.

A federal court in Indiana earlier this month unsealed an indictment charging 30-year-old Guan Tianfeng (Guan) with conspiracy to commit computer and wire fraud by hacking into firewall devices worldwide, including one "used by an agency of the United States." Guan, employed by the Chinese cybersecurity firm Sichuan Silence -- a known contractor for Beijing intelligence -- was alleged to have discovered a zero-day vulnerability in firewall products manufactured by UK cybersecurity firm Sophos.

Thirteen vapes are thrown away every second in the UK -- more than a million a day -- leading to an "environmental nightmare," according to research. From a report: There has also been a rise in "big puff" vapes which are bigger and can hold up to 6,000 puffs per vape, with single use vapes averaging 600. Three million of these larger vapes are being bought every week according to the research, commissioned by Material Focus, and conducted by Opinium. 8.2 million vapes are now thrown away or recycled incorrectly every week.

From June 2025 it will be illegal to sell single-use vapes, a move designed to combat environmental damage and their widespread use by children. Vapes will only be allowed to be sold if they are rechargeable or contain a refillable cartridge.

But all types of vape contain lithium-ion batteries which are dangerous if crushed or damaged because they can cause fires in bin lorries or waste and recycling centres. These fires are on the rise across the UK, with an increase last year of 71% compared with 2022.
