An anonymous reader quotes a report from Wired: On a side street outside the headquarters of the Department of Science, Innovation and Technology in the center of London on Monday, 20 or so protesters are getting their chants in order. "What do we want? Safe AI! When do we want it?" The protesters hesitate. "Later?" someone offers. The group of mostly young men huddle for a moment before breaking into a new chant. "What do we want? Pause AI! When do we want it? Now!" These protesters are part of Pause AI, a group of activists petitioning for companies to pause development of large AI models which they fear could pose a risk to the future of humanity. Other PauseAI protests are taking place across the globe: In San Francisco, New York, Berlin, Rome, Ottawa, and ahandful of other cities. Their aim is to grab the attention of voters and politicians ahead of the AI Seoul Summit -- a follow-up to the AI Safety Summit held in the UK in November 2023. But the loosely organized group of protesters itself is still figuring out exactly the best way to communicate its message.

"The Summit didn't actually lead to meaningful regulations," says Joep Meindertsma, the founder of PauseAI. The attendees at the conference agreed to the "Bletchley Declaration," but that agreement doesn't mean much, Meindertsma says. "It's only a small first step, and what we need are binding international treaties." [...] There is also the question of how PauseAI should achieve its aims. On the group's Discord, some members discussed the idea of staging sit-ins at the headquarters of AI developers. OpenAI, in particular, has become a focal point of AI protests. In February, Pause AI protests gathered in front of OpenAI'sSan Francisco offices, after the company changed its usage policies to remove a ban on military and warfare applications for its products. Would it be too disruptive if protests staged sit-ins or chained themselves to the doors of AI developers, one member of the Discord asked. "Probably not. We do what we have to, in the end, for a future with humanity, while we still can." [...]

Director of Pause AI US, Holly Elmore, wants the movement to be a "broad church" that includes artists, writers, and copyright owners whose livelihoods are put at risk from AI systems that can mimic creative works. "I'm a utilitarian. I'm thinking about the consequences ultimately, but the injustice that really drives me to do this kind of activism is the lack of consent" from companies producing AI models, she says. "We don't have to choose which AI harm is the most important when we're talking about pausing as a solution. Pause is the only solution that addresses all of them." [Joseph Miller, the organizer of PauseAI's protest in London] echoed this point. He says he's spoken to artists whose livelihoods have been impacted by the growth of AI art generators. "These are problems that are real today, and are signs of much more dangerous things to come." One of the London protesters, Gideon Futerman, has a stack of leaflets he's attempting to hand out to civil servants leaving the building opposite. He has been protesting with the group since last year. "The idea of a pause being possible has really taken root since then," he says. According to Wired, the leaders of Pause AI said they were not considering sit-ins or encampments near AI offices at this time. "Our tactics and our methods are actually very moderate," says Elmore. "I want to be the moderate base for a lot of organizations in this space. I'm sure we would never condone violence. I also want Pause AI to go further than that and just be very trustworthy."

Meindertsma agrees, saying that more disruptive action isn't justified at the moment. "I truly hope that we don't need to take other actions. I don't expect that we'll need to. I don't feel like I'm the type of person to lead a movement that isn't completely legal."

Slashdotters, what is the most effective way to protest AI development? Is the AI genie out of the bottle? Curious to hear your thoughts

Slashdot reader quonset writes: The last floppy disk was manufactured in 2011. Despite no new supplies being available for over a decade, there are still people, and organizations, who rely on floppy disks. Each has their own story as to why they rely on what is essentially 1970s technology.
From the BBC: Tom Persky, a US businessman, has been selling "new", as in, unopened, floppy disks for years and still finds the trade lucrative. He runs Floppydisk.com, which offers disks for about US$1 (£0.80) each, though some higher capacity versions cost up to US$10 (£8) per disk, he says. Persky has customers all over the world and you could split them roughly 50-50 into hobbyists and enthusiasts like Espen Kraft on one side, and industrial users on the other. This latter category encompasses people who use computers at work that require floppy disks to function. They are, essentially, locked in to a format that the rest of the world has largely forgotten.

"I sell thousands of floppy disks to the airline industry, still," says Persky. He declines to elaborate. "Companies are not happy about when I talk about them." But it is well-known that some Boeing 747s, for example, use floppy disks to load critical software updates into their navigation and avionics computers. While these older aircraft might not be so common in Europe or the US these days, you might find one in the developing world, for instance, Persky hints. There are also pieces of factory equipment, government systems — or even animatronic figures — that still rely on floppy disks.

And in San Francisco, the Muni Metro light railway, which launched in 1980, won't start up each morning unless the staff in charge pick up a floppy disk and slip it into the computer that controls the railway's Automatic Train Control System, or ATCS. "The computer has to be told what it's supposed to do every day," explains a spokesman for the San Francisco Municipal Transport Agency (SFMTA). "Without a hard drive, there is nowhere to install software on a permanent basis."

This computer has to be restarted in such a way repeatedly, he adds — it can't simply be left on, for fear of its memory degrading.
The article also includes this quote from a cybersecurity expert at Pen Test Partners. "If floppy was the only interface, the only way to get malware on to [the computer] would be via said floppy disk. That's quite a limiting factor for the attacker..."

An anonymous reader quotes a report from The Guardian: A British toddler has had her hearing restored after becoming the first person in the world to take part in a pioneering gene therapy trial, in a development that doctors say marks a new era in treating deafness. Opal Sandy was born unable to hear anything due to auditory neuropathy, a condition that disrupts nerve impulses traveling from the inner ear to the brain and can be caused by a faulty gene. But after receiving an infusion containing a working copy of the gene during groundbreaking surgery that took just 16 minutes, the 18-month-old can hear almost perfectly and enjoys playing with toy drums. [...] The girl, from Oxfordshire, was treated at Addenbrooke's hospital, part of Cambridge university hospitals NHS foundation trust, which is running the Chord trial. More deaf children from the UK, Spain and the US are being recruited to the trial and will all be followed up for five years. [...]

Auditory neuropathy can be caused by a fault in the OTOF gene, which makes a protein called otoferlin. This enables cells in the ear to communicate with the hearing nerve. To overcome the fault, the new therapy from biotech firm Regeneron sends a working copy of the gene to the ear. A second child has also recently received the gene therapy treatment at Cambridge university hospitals, with positive results. The overall Chord trial consists of three parts, with three deaf children including Opal receiving a low dose of gene therapy in one ear only. A different set of three children will get a high dose on one side. Then, if that is shown to be safe, more children will receive a dose in both ears at the same time. In total, 18 children worldwide will be recruited to the trial. The gene therapy -- DB-OTO -- is specifically for children with OTOF mutations. A harmless virus is used to carry the working gene into the patient.

The U.K. economy has emerged from recession as gross domestic product rose 0.6% in the first quarter, official figures showed Friday, beating expectations. From a report: Economists polled by Reuters had forecast growth of 0.4% on the previous three months of the year. The U.K. entered a shallow recession in the second half of 2023, as persistent inflation continued to hurt the economy.

Although there is no official definition of a recession, two straight quarters of negative growth is widely considered a technical recession. The U.K.'s production sector expanded by 0.8% in the period from January to March, while construction fell by 0.9%. On a monthly basis, the economy grew by 0.4% in March, following 0.2% expansion in February. In output terms, the services sector -- crucial to the U.K. economy -- grew for the first time since the first quarter in 2023, the Office for National Statistics said. The 0.7% growth was mainly driven by the transport services industry which saw its highest quarterly growth rate since 2020.

The North Yorkshire Council in England announced it will ban apostrophes on street signs as it can affect geographical databases. Resident Anne Keywood told the BBC that she urged the authority to retain apostrophes, saying: "If you start losing things like that then everything goes downhill doesn't it?" From the report: North Yorkshire Council said it "along with many others across the country" had opted to "eliminate" the apostrophe from street signs. A spokesperson added: "All punctuation will be considered but avoided where possible because street names and addresses, when stored in databases, must meet the standards (PDF) set out in BS7666.

"This restricts the use of punctuation marks and special characters (e.g. apostrophes, hyphens and ampersands) to avoid potential problems when searching the databases as these characters have specific meanings in computer systems."

Wayve, a UK-based AI firm focused on developing self-driving car technology, has secured a record $1.05 billion in funding, with Microsoft and Nvidia participating in the round led by SoftBank. According to the BBC, this investment is the largest for an AI company in Europe. The BBC reports: Wayve says the funding will allow it to help build the autonomous cars of the future. [...] Wayve is developing technology intended to power future self-driving vehicles by using what it calls "embodied AI." Unlike AI models carrying out cognitive or generative tasks such as answering questions or creating pictures, this new technology interacts with and learns from real-world surroundings and environments. "[The investment] sends a crucial signal to the market of the strength of the UK's AI ecosystem, and we look forward to watching more AI companies here thrive and scale," said Wayve head Alex Kendall.

The identity of the leader of one of the most infamous ransomware groups in history has finally been revealed. From a report: On Tuesday, a coalition of law enforcement led by the U.K.'s National Crime Agency announced that Russian national, Dmitry Yuryevich Khoroshev, 31, is the person behind the nickname LockBitSupp, the administrator and developer of the LockBit ransomware. The U.S. Department of Justice also announced the indictment of Khoroshev, accusing him of computer crimes, fraud and extortion.

"Today we are going a step further, charging the individual who we allege developed and administered this malicious cyber scheme, which has targeted over 2,000 victims and stolen more than $100 million in ransomware payments," Attorney General Merrick B. Garland was quoted as saying in the announcement. According to the DOJ, Khoroshev is from Voronezh, a city in Russia around 300 miles south of Moscow. "Dmitry Khoroshev conceived, developed, and administered Lockbit, the most prolific ransomware variant and group in the world, enabling himself and his affiliates to wreak havoc and cause billions of dollars in damage to thousands of victims around the globe," said U.S. Attorney Philip R. Sellinger for the District of New Jersey, where Khoroshev was indicted.

A council has provoked the wrath of residents and linguists alike after announcing it would ban apostrophes on street signs to avoid problems with computer systems. From a report: North Yorkshire council is ditching the punctuation point after careful consideration, saying it can affect geographical databases. The council said all new street signs would be produced without one, regardless of whether they were used in the past. Some residents expressed reservations about removing the apostrophes, and said it risked "everything going downhill." They urged the authority to retain them.

Sam, a postal worker in Harrogate, a spa town in North Yorkshire, told the BBC that signs missing an apostrophe -- such as the nearby St Mary's Walk sign that had been erected in the town without it -- infuriated her. "I walk past the sign every day and it riles my blood to see inappropriate grammar or punctuation," she said. Though the updated St Mary's sign had no apostrophe, someone had graffitied an apostrophe back on to the sign with a marker pen, which the former teacher said was "brilliant." She suggested the council was providing a bad example to children who spend a long time learning the basics of grammar only to see it not being used correctly on street signs.

Dr Ellie Rye, a lecturer in English language and linguistics at the University of York, said apostrophes were a relatively new invention in our writing and, often, context allows people to understand their meaning. "If I say I live on St Mary's Walk, we're expecting a street name or an address of some kind." She said the change would matter to people who spend a long time teaching how we write English but that it was "less important in [verbal] communication."

An anonymous reader quotes a report from The Guardian: Oil and gas equipment intended to cut methane emissions is preventing scientists from accurately detecting greenhouse gases and pollutants, a satellite image investigation has revealed. Energy companies operating in countries such as the US, UK, Germany and Norway appear to have installed technology that could stop researchers from identifying methane, carbon dioxide emissions and pollutants at industrial facilities involved in the disposal of unprofitable natural gas, known in the industry as flaring. Flares are used by fossil fuel companies when capturing the natural gas would cost more than they can make by selling it. They release carbon dioxide and toxic pollutants when they burn as well as cancer-causing chemicals. Despite the health risks, regulators sometimes prefer flaring to releasing natural gas -- which is 90% methane -- directly into the atmosphere, known as "venting".

The World Bank, alongside the EU and other regulators, have been using satellites for years to find and document gas flares, asking energy companies to find ways of capturing the gas instead of burning or venting it. The bank set up the Zero Routine Flaring 2030 initiative at the Paris climate conference to eradicate unnecessary flaring, and its latest report stated that flaring decreased by 3% globally from 2021 to 2022. But since the initiative, "enclosed combustors" have begun appearing in the same countries that promised to end flaring. Experts say enclosed combustors are functionally the same as flares, except the flame is hidden. Tim Doty, a former regulator at the Texas Commission on Environmental Quality, said: "Enclosed combustors are basically a flare with an internal flare tip that you don't see. Enclosed flaring is still flaring. It's just different infrastructure that they're allowing.

"Enclosed flaring is, in truth, probably less efficient than a typical flare. It's better than venting, but going from a flare to an enclosed flare or a vapor combustor is not an improvement in reducing emissions." The only method of detecting flaring globally is by using satellite-mounted tools called Visible Infrared Imaging Radiometer Suite of detectors (VIIRS), which find flares by comparing heat signatures with bright spots of light visible from space. But when researchers tried to replicate the database, they saw that the satellites were not picking up the enclosed flares. Without the satellite data, countries were forced to rely mostly on self-disclosed reporting from oil and gas companies, researchers said. Environmentalists fear the research community's ability to understand pollution and greenhouse gas emissions from the energy sector could be jeopardized.

An anonymous reader quotes a report from The Independent, published last month: Humans now share the web equally with bots, according to a major new report -- as some fear that the internet is dying. In recent months, the so-called "dead internet theory" has gained new popularity. It suggests that much of the content online is in fact automatically generated, and that the number of humans on the web is dwindling in comparison with bot accounts. Now a new report from cyber security company Imperva suggests that it is increasingly becoming true. Nearly half, 49.6 per cent, of all internet traffic came from bots last year, its "Bad Bot Report" indicates. That is up 2 percent in comparison with last year, and is the highest number ever seen since the report began in 2013. In some countries, the picture is worse. In Ireland, 71 per cent of internet traffic is automated, it said.

Some of that rise is the result of the adoption of generative artificial intelligence and large language models. Companies that build those systems use bots scrape the internet and gather data that can then be used to train them. Some of those bots are becoming increasingly sophisticated, Imperva warned. More and more of them come from residential internet connections, which makes them look more legitimate. "Automated bots will soon surpass the proportion of internet traffic coming from humans, changing the way that organizations approach building and protecting their websites and applications," said Nanhi Singh, general manager for application security at Imperva. "As more AI-enabled tools are introduced, bots will become omnipresent."

The UK government's climate action plan is unlawful, the high court has ruled, as there is not enough evidence that there are sufficient policies in place to reduce greenhouse gas emissions. From a report: The energy secretary, Claire Coutinho, will now be expected to draw up a revised plan within 12 months. This must ensure that the UK achieves its legally binding carbon budgets and its pledge to cut emissions by more than two-thirds by 2030, both of which the government is off track to meet. The environmental charities Friends of the Earth and ClientEarth took joint legal action with the Good Law Project against the Department for Energy Security and Net Zero (DESNZ) over its decision to approve the carbon budget delivery plan (CBDP) in March 2023.

In a ruling on Friday, Mr Justice Sheldon upheld four of the five grounds of the groups' legal challenge, stating that the decision by the former energy security and net zero secretary Grant Shapps was "simply not justified by the evidence." He said: "If, as I have found, the secretary of state did make his decision on the assumption that each of the proposals and policies would be delivered in full, then the secretary of state's decision was taken on the basis of a mistaken understanding of the true factual position."

The judge agreed with ClientEarth and Friends of the Earth that the secretary of state was given "incomplete" information about the likelihood that proposed policies would achieve their intended emissions cuts. This breached section 13 of the Climate Change Act, which requires the secretary of state to adopt plans and proposals that they consider will enable upcoming carbon budgets to be delivered. Sheldon also agreed with the environment groups that the central assumption that all the department's policies would achieve 100% of their intended emissions cuts was wrong. The judge said the secretary of state had acted irrationally, and on the basis of an incorrect understanding of the facts. This comes after the Guardian revealed the government would be allowing oil and gas drilling under offshore wind turbines, a decision criticised by climate experts as "deeply irresponsible."

An anonymous reader quotes a report from Reuters: Energy ministers from the Group of Seven (G7) major democracies reached a deal to shut down their coal-fired power plants in the first half of the 2030s, in a significant step towards the transition away from fossil fuels. "There is a technical agreement, we will seal the final political deal on Tuesday," said Italian energy minister Gilberto Pichetto Fratin, who is chairing the G7 ministerial meeting in Turin. On Tuesday the ministers will issue a final communique detailing the G7 commitments to decarbonize their economies. Pichetto said the ministers were also pondering potential restrictions to Russian imports of liquefied natural gas to Europe which the European Commission is due to propose in the short-term.

The agreement on coal marks a significant step in the direction indicated last year by the COP28 United Nations climate summit to phase out fossil fuels, of which coal is the most polluting. Italy last year produced 4.7% of its total electricity through a handful of coal-fired stations. Rome currently plans to turn off its plants by 2025, except on the island of Sardinia where the deadline is 2028. In Germany and Japan coal has a bigger role, with the share of electricity produced by the fuel higher than 25% of total last year. "This is another nail in the coffin for coal," said Dave Jones, Ember's Global Insights program director. "The journey to phase out coal power has been long: it's been over seven years since the UK, France, Italy, and Canada committed to phase out coal power, so it's good to see the United States and especially Japan at last be more explicit on their intentions."

"The problem is that whilst coal power has already been falling, gas power has not. G7 nations already promised to 'fully or predominantly' decarbonize their power sectors by 2035, and that would mean phasing out not only coal by 2035 but also gas. Coal might be the dirtiest, but all fossil fuels need to be ultimately phased out."

Longtime Slashdot reader ArchieBunker shares a report from The Mirror: The city court in Syktyvkar, the largest city in Russia's northwestern Komi region, announced it had arrested [former world chess champion Garry Kasparov] in absentia alongside former Russian parliament member Gennady Gudkov, Ivan Tyutrin co-founder of the Free Russia Forum -- which has been designated as an "undesirable organization in the country -- as well as former environmental activist Yevgenia Chirikova. All were charged with setting up a terrorist society, according to the court's press service. As all were charged in their absence, none were physically held in custody.

"The court has selected a measure of restraint for Garry Kasparov, Gennady Gudkov, Yevgenia Chirikova and Ivan Tyutrin, charged with establishing and heading a terrorist society, funding terrorist activity and justifying it publicly," the court said according to Kremlin-backed outlet TASS. "The court granted the investigative bodies' motions to remand Kasparov, Gudkov, Chirikova and Tyutrin in custody as a measure of restraint."

Kasparov responded to the court's bizarre arrest statement in an April 24 post shared on X, formerly Twitter. "In absentia is definitely the best way I've ever been arrested," he said. "Good company, as well. I'm sure we're all equally honored that Putin's terror state is spending time on this that would otherwise go persecuting and murdering." The report notes that Kasparov "found himself in Russian President Vladimir Putin's firing line after he voiced his opposition to the country's leader." The report continues: "He has also pursued pro-democracy initiatives in Russia. But he felt unable to continue living in Russia after he was jailed and allegedly beaten by police in 2012, according to the Guardian. He was granted Croatian citizenship in 2014 following repeated difficulties in Russia."

The United Kingdom has become the first country in the world to ban default guessable usernames and passwords from these IoT devices. Unique passwords installed by default are still permitted. From a report: The Product Security and Telecommunications Infrastructure Act 2022 (PSTI) introduces new minimum-security standards for manufacturers, and demands that these companies are open with consumers about how long their products will receive security updates for.

Manufacturing and design practices mean many IoT products introduce additional risks to the home and business networks they're connected to. In one often-cited case described by cybersecurity company Darktrace, hackers were allegedly able to steal data from a casino's otherwise well-protected computer network after breaking in through an internet-connected temperature sensor in a fish tank. Under the PSTI, weak or easily guessable default passwords such as "admin" or "12345" are explicitly banned, and manufacturers are also required to publish contact details so users can report bugs.

In September NASA's James Webb Space Telescope investigated an exoplanet 8.6 times as massive as Earth, and "revealed the presence of carbon-bearing molecules including methane and carbon dioxide." Webb's discovery adds to recent studies suggesting that [planet] K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface... The planet's large size — with a radius 2.6 times the radius of Earth — means that the planet's interior likely contains a large mantle of high-pressure ice, like Neptune, but with a thinner hydrogen-rich atmosphere and an ocean surface. Hycean worlds are predicted to have oceans of water. However, it is also possible that the ocean is too hot to be habitable or be liquid.
NASA's announcement included some additional context: K2-18 b orbits the cool dwarf star K2-18 in the habitable zone and lies 120 light-years from Earth in the constellation Leo. Exoplanets such as K2-18 b, which have sizes between those of Earth and Neptune, are unlike anything in our solar system. This lack of equivalent nearby planets means that these 'sub-Neptunes' are poorly understood, and the nature of their atmospheres is a matter of active debate among astronomers. The suggestion that the sub-Neptune K2-18 b could be a Hycean exoplanet is intriguing, as some astronomers believe that these worlds are promising environments to search for evidence for life on exoplanets...

The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b.
Long-time Slashdot reader Baron_Yam noticed some sites resurfacing the news from September this week with more spectacular headlines, like "NASA discovered a planet twice as big as Earth with a gas that is 'only produced by life'" and "Discovery... sparks huge excitement among astronomers.

NASA's announcement? It's early Webb observations "provided a possible detection of a molecule called dimethyl sulfide. On Earth, this is only produced by life." The bulk of the dimethyl sulfide in Earth's atmosphere is emitted from phytoplankton in marine environments.

The inference of dimethyl sulfide is less robust and requires further validation. "Upcoming Webb observations should be able to confirm if dimethyl sulfide is indeed present in the atmosphere of K2-18 b at significant levels," explained Nikku Madhusudhan, an astronomer at the University of Cambridge and lead author of the paper announcing these results.

While K2-18 b lies in the habitable zone, and is now known to harbor carbon-bearing molecules, this does not necessarily mean that the planet can support life.
But it's all a validation of the new discoveries being made possible by space telescopes — new and old. "The first insight into the atmospheric properties of this habitable-zone exoplanet came from observations with NASA's Hubble Space Telescope, which prompted further studies..." "This result was only possible because of the extended wavelength range and unprecedented sensitivity of Webb, which enabled robust detection of spectral features with just two transits," said Madhusudhan... "These results are the product of just two observations of K2-18 b, with many more on the way," explained team member Savvas Constantinou of the University of Cambridge. "This means our work here is but an early demonstration of what Webb can observe in habitable-zone exoplanets."

[...] The team now intends to conduct follow-up research with the telescope's MIRI (Mid-Infrared Instrument) spectrograph that they hope will further validate their findings and provide new insights into the environmental conditions on K2-18 b. "Our ultimate goal is the identification of life on a habitable exoplanet, which would transform our understanding of our place in the universe," concluded Madhusudhan. "Our findings are a promising step towards a deeper understanding of Hycean worlds in this quest."

"For the first time in at least a billion years, two lifeforms have merged into a single organism," reports the Independent: The process, called primary endosymbiosis, has only happened twice in the history of the Earth, with the first time giving rise to all complex life as we know it through mitochondria. The second time that it happened saw the emergence of plants. Now, an international team of scientists have observed the evolutionary event happening between a species of algae commonly found in the ocean and a bacterium...

The process involves the algae engulfing the bacterium and providing it with nutrients, energy and protection in return for functions that it could not previously perform — in this instance, the ability to "fix" nitrogen from the air. The algae then incorporates the bacterium as an internal organ called an organelle, which becomes vital to the host's ability to function.

The researchers from the U.S. and Japan who made the discovery said it will offer new insights into the process of evolution, while also holding the potential to fundamentally change agriculture. "This system is a new perspective on nitrogen fixation, and it might provide clues into how such an organelle could be engineered into crop plants," said Dr Coale.
Two papers detailing the research were published in the scientific journals Science and Cell.

An anonymous reader quotes a report from TechCrunch: Darktrace is set to go private in a deal that values the U.K.-based cybersecurity giant at around $5 billion. A newly formed entity called Luke Bidco Ltd., formed by private equity giant Thoma Bravo, has tabled an all-cash bid of $7.75 per share, which represents a 44% premium on its average price for the three-month period ending April 25. However, this premium drops to just 20% when juxtaposed against Darktrace's closing price Thursday, as the company's shares had risen 20% to 5.18 pounds in the past month.

Founded out of Cambridge, U.K., in 2013, Darktrace is best known for AI-enabled threat detection smarts, using machine learning to identify abnormal network activity and attempts at ransomware attacks, insider attacks, data breaches and more. The company claims big-name customers including Allianz, Airbus and the city of Las Vegas. After raising some $230 million in VC funding and hitting a private valuation of $1.65 billion, Darktrace went public on the London Stock Exchange in April 2021, with an opening-day valuation of $2.4 billion. Its shares hit an all-time high later that year of 9.45 pounds and plummeted to an all-time low of 2.29 pounds last February. But they had been steadily rising since the turn of the year and hadn't fallen below 4 pounds since the beginning of March.

The full valuation based on Thoma Bravo's offer amounts to $5.3 billion on what is known as a full-diluted basis, which takes into account all convertible securities and is designed to give a more comprehensive view of a company's valuation. However, the enterprise value in this instance is approximately $4.9 billion, which includes additional considerations such as debt and cash positions. [...] The deal is of course still subject to shareholder approval, but the companies said that they expect to complete the transaction by the end of 2024. "The proposed offer represents an attractive premium and an opportunity for shareholders to receive the certainty of a cash consideration at a fair value for their shares," Darktrace chair Gordon Hurst said. "The proposed acquisition will provide Darktrace access to a strong financial partner in Thoma Bravo, with deep software sector expertise, who can enhance the company's position as a best-in-class cyber AI business headquartered in the U.K."

The head of Britain's domestic intelligence agency warned the country's leading research universities on Thursday that foreign states are targeting their institutions and imperilling national security. The Record: "We know that our universities are being actively targeted by hostile actors and need to guard against the threat posed to frontier research in the most sensitive sectors," said the deputy prime minister Oliver Dowden, who also attended the briefing. The threat requires "further measures," said the deputy PM, who announced that the government was launching a consultation with the sector so it could "do more to support our universities and put the right security in place to protect their cutting-edge research."

The briefing was delivered by Ken McCallum, the director general of MI5, alongside Dowden and the National Cyber Security Centre's interim chief executive, Felicity Oswald. It was made to the vice-chancellors of the Russell Group, a collective of the country's 24 leading universities. Among the range of measures being considered is having MI5, the domestic security agency, carry out security vetting on key researchers involved in a "small proportion of academic work, with a particular focus on research with potential dual uses in civilian and military life."

Europe is less hard-working, less ambitious, more regulated and more risk-averse than the US, according to the boss of Norway's giant oil fund, with the gap between the two continents only getting wider. FT: Nicolai Tangen, chief executive of the $1.6tn fund, told the Financial Times it was "worrisome" that American companies were outpacing their European rivals [non paywalled link] on innovation and technology, leading to vast outperformance of US shares in the past decade. "There's a mindset issue in terms of acceptance of mistakes and risks. You go bust in America, you get another chance. In Europe, you're dead," he said, adding that there was also a difference in "the general level of ambition. We are not very ambitious. I should be careful about talking about work-life balance, but the Americans just work harder."

His views are significant as the oil fund is one of the largest single investors in the world, owning on average 1.5 per cent of every listed company globally and 2.5 per cent of every European equity. Its US holdings have increased in the past decade while its European ones have declined. US shares account for almost half of all its equities compared with 32 per cent in 2013. The leading European country -- the UK -- represented 15 per cent of its equity portfolio a decade ago but just 6 per cent last year.

Samantha Cole reports via 404 Media: A Japan-based online art platform is banning kink content for users based in the US and UK, as laws in these countries continue to tighten around sites that allow erotic content. Pixiv is an image gallery site where artists primarily share illustrations, manga, and novels. The site announced on April 22 that starting April 25, users whose account region is set to the US or UK will be subject to Pixiv's new terms of use, "Restrictions for Healthy Expression in Specific Countries and Regions."

The restrictions include several kinds of content that are illegal in the US, including sexualized depictions of minors and bestiality, as well as non-consensual depictions and deepfakes.
