Microsoft’s attempt to buy the developer of Call of Duty in the biggest tech deal ever may be pressing ahead. A judge ruled that Microsoft could go ahead with its purchase of Activision, despite objections from its rival PlayStation. The US Federal Trade Commission had attempted to block the deal amid fears that it could limit competition in gaming. But the court said that it would not stop the deal. Now the UK’s Competition and Markets Authority, which originally blocked the deal earlier this year, said that it would consider new proposals from Microsoft that might make the deal reach approval in the UK, too. “After today’s court decision in the US, our focus now turns back to the UK,” said Brad Smith, vice chair and president at Microsoft. “While we ultimately disagree with the CMA’s concerns, we are considering how the transaction might be modified in order to address those concerns in a way that is acceptable to the CMA. “In order to prioritize work on these proposals, Microsoft and Activision have agreed with the CMA that a stay of the litigation in the UK would be in the public interest and the parties have made a joint submission to the Competition Appeal Tribunal to this effect.” The deal would be the largest for Microsoft and the biggest in the history of the videogame business. In its arguments, the FTC has said Microsoft would be able to use the Activision games to leave rival console makers like Nintendo and market-leader Sony Group out in the cold. Microsoft President Brad Smith tweeted that the company was “grateful” for the “quick and thorough” decision. “Our merger will benefit consumers and workers. It will enable competition rather than allow entrenched market leaders to continue to dominate our rapidly growing industry,â€Â Bobby Kotick, Activision Blizzard CEO, said in a statement. The FTC’s complaint had cited concerns about loss of competition in console gaming, as well as subscriptions and cloud gaming. To address the FTC’s concerns, Microsoft agreed to license “Call of Duty” to rivals, including a 10-year contract with Nintendo, contingent on the merger closing. During the five-day trial in June, Microsoft CEO Satya Nadella argued the company would have no incentive to shut out Sony’s PlayStation or other rivals in order to sell more Microsoft Xbox consoles. At issue in the Microsoft-Activision deal is leadership in a gaming market whose sales are expected to increase by 36% over the next four years to $321 billion, according to a PwC estimate. And while much of the testimony in the recent trial focused on “Call of Duty,” Activision produces other bestsellers like “World of Warcraft,” “Diablo” and the mobile game “Candy Crush Saga.” Additional reporting by Reuters Read More Microsoft Teams stops working in the middle of the working day Scientists invent cloak inspired by Roman god that could help us live on Mars Record-breaking sugar battery could supercharge transition to renewable energy Scientists invent cloak inspired by Roman god that could help us live on Mars Record-breaking sugar battery could supercharge transition to renewable energy Why the Battle of the Boyne has made its way into your iPhone

A well-known biochemist has shared a compelling analysis of what “probably” caused the Titan submersible to implode. Philip E. Mason, who goes by the username Thunderf00t on YouTube, said the main reason why the tiny OceanGate vessel failed was “so painfully simple” that he initially thought he must be making a “boneheaded mistake” in his calculations. However, he acknowledged, his theory behind the sub’s tragic destruction contradicts the widely-reported suggestion that it was like a "Coke can" which suddenly burst due to the high surrounding pressure. In a video posted on Monday, Mason suggested that “by far the most probable” cause of the catastrophe was a “single pinhole leak” which, at such a profound depth (the Titan is believed to have been 3,500 metres below sea level when contact was lost), would have been fatal. It is worth noting that authorities have not yet confirmed the cause of the disaster, which claimed the lives of all five people on board, and Mason's conclusions are based on his own scrutiny of the available information and his particular expertise. Sign up for our free Indy100 weekly newsletter “So how quickly would a single pinhole leak sink a sub like this?” the YouTuber asked in his lengthy tutorial. The answer, he pointed out, would greatly depend on the size of the leak. If it measured one 10th of a millimetre by one 10th of a millimetre, the vessel would take several hours to go down, he said. However, if the leak measured 1mm by 1mm, it would only take about 10 minutes for the sub to completely fill with water, and if it was 1cm by 1cm, around 10 seconds. Mason then pointed out that water entering any sized leak at that depth would be transformed by the pressure into a sort of “cutting jet”. “Faced with a soft material like plastic, a hair-sized leak would rapidly transform into [...] a millimetre-sized leak and then a centimetre-sized leak,” he explained. Why the Titan sub failed www.youtube.com He then set out why it was likely that the Titan suffered such a leak, pointing to the materials used to make it. He noted that most deep-sea submersibles essentially consist of a ball which is made up entirely of the same material, namely, metal. “No joints, nothing fancy, maybe a couple of seals – one for where you get in and out of the sub and one for mounting a window,” he said. And yet, the Titan was different. “The ends were made up of a metal, titanium,” the YouTuber said. But the problem was that the middle of the sub wasn’t: it was made out of a carbon fibre composite. The two materials have distinctly different compressibilities, with carbon fibre being much easier to squeeze than titanium. “Having a joint where one side will expand or construct more than the other can be a real problem,” Mason stressed. On the surface, when the different components of the vessel were sealed, it wouldn’t have mattered that the materials were different, he continued. However, once the Titan got down to its deepest point, the carbon fibre would have “wanted to shrink” while the titanium wouldn't have changed at all. He then played a clip showing the creation of the sub, in which OceanGate CEO, Stockton Rush, admitted that the carbon fibre and titanium components were held together with a “peanut butter”-like “glue”. Rush, who lost his life along with five others in the Titan disaster, then said ominously: “It’s pretty simple but if we mess it up, there's not a lot of recovery.” Analysing the vessel's construction, Mason then said he was “honestly stunned it survived any dives”. “The bottom line is the tube is more compressible than the end caps,” he continued. “The only way this could have possibly worked is if they used some exotic alloy of titanium, like they do with bone replacement joints, and it doesn't look like they did that.” Turning to what ultimately destroyed the Titan, he concluded: “What you're probably more looking at is the differential compression of the carbon fibre composite and the titanium resulting in a crack.” In other words, “a pinhole leak, which would rapidly widen due to the rapid ingress of the water, further widening the crack and the rapid flooding of the sub in probably a fraction of a second. “And when that water hammer hits the end of the sub, it's likely that the sub broke into pieces.” Wrapping up his video, he said: “It's a mind-blowingly simple explanation based around the most likely failure points.” Investigators are continuing to examine wreckage from the submersible which was recovered from the ocean floor at the end of June. They have yet to determine the cause of the explosion and, last week, the Marine Board of Investigation’s (MBI) chairman Captain Jason Neubauer said: “There is still a substantial amount of work to be done to understand the factors that led to the catastrophic loss of the Titan and help ensure a similar tragedy does not occur again.” Have your say in our news democracy.

Scientists have invented a cloak inspired by Roman mythology that can cool anything it covers during the day and warm it up at night. The Janus thermal cloak, named after the two-faced Roman god Janus, could be used in everything from electric cars to space craft, with the researchers claiming it could even be used to build off-planet colonies on the Moon and Mars. “The thermal cloak is like clothes for vehicles, buildings, spacecrafts, or even extraterrestrial habitats to keep cool in summer and warm in winter,” said Kehang Cui, a materials scientist at Shanghai Jiao Tong University, who was involved in the research. “The cloak works basically the same way the Earth cools down, through relative cooling. The Earth is covered by the atmosphere, and the atmosphere is transparent to a certain range of electromagnetic energy we radiate.” The futuristic material, made of silica and aluminium, is able to achieve the heating and cooling effect passively, without the need for any outside energy. Covering electric vehicles in the cloak helps to cool them 8°C on a hot day and warm them 6.8°C on a cold night, helping to prevent deterioration of the battery. “This is the first time that we could achieve warming above the ambient temperature by almost 7°C during winter nights,” said Professor Cui. “This is also kind of surprising to us – there’s no energy input or sunshine and we can still get warming.” A study detailing the research, titled ‘Scalable and durable Janus thermal cloak for all-season passive thermal regulation’, was published in the scientific journal Device on Tuesday.
