The Japanese city of Toyoake has passed (PDF) a symbolic ordinance limiting recreational smartphone use to two hours a day, aiming to improve citizens' sleep -- especially for students after summer vacation. The Register reports: "The primary purpose of this ordinance is to ensure that all citizens receive adequate sleep," states a Council information page, which explains that many Japanese people ignore Ministry of Health, Labor and Welfare recommendations to spend six to eight hours a day dozing. An accompanying FAQ [PDF] explains that Council passed the ordinance because students who return to school after summer vacations sometimes need a nudge the re-establish an appropriate daily regime.

The ordinance also points out "Excessive phone users and their families are facing difficulties in their daily and social lives," and suggests the two-hours-a-day guidance might help. Council's documents point out that smartphones have myriad uses beyond recreation, and that the ordinance should not be taken as a suggestion to reduce overall use of the devices. Toyoake is part of the Nagoya megalopolis and is home to around 70,000 people. The town's government plans to survey residents about the ordinance, and the FAQ also mentions it wants to tackle other digital menaces, among them harmful effects of using smartphones while walking.

An anonymous reader quotes a report from Reuters: OpenAI, Oracle, and SoftBank on Tuesday announced plans for five new artificial intelligence data centers in the United States to build out their ambitious Stargate project. [...] ChatGPT-maker OpenAI said on Tuesday it will open three new sites with Oracle in Shackelford County, Texas, Dona Ana County, New Mexico and an undisclosed site in the Midwest. Two more data center sites will be built in Lordstown, Ohio and Milam County, Texas by OpenAI, Japan's SoftBank and a SoftBank affiliate.

The new sites, the Oracle-OpenAI site expansion in Abilene, Texas, and the ongoing projects with CoreWeave will bring Stargate's total data center capacity to nearly 7 gigawatts and more than $400 billion in investment over the next three years, OpenAI said. The $500 billion project was intended to generate 10 gigawatts in total data center capacity. "AI can only fulfill its promise if we build the compute to power it," OpenAI CEO Sam Altman said in a statement. The Tuesday's announcement, expected to create 25,000 onsite jobs, follows Nvidia saying on Monday that it will invest up to $100 billion in OpenAI and supply data center chips. OpenAI and partners plan to use debt financing to lease chips for the Stargate project, people familiar with the matter said.

A large U.S.-made bomb left over from World War II was discovered at a construction site, reports the Associated Press: Police said the bomb was 1.5 meters (nearly 5 feet) in length and weighed about 1,000 pounds (450 kilograms). It was discovered by construction workers in Quarry Bay, a bustling residential and business district on the west side of Hong Kong island... [A police official] said that because of "the exceptionally high risks associated with its disposal," approximately 1,900 households involving 6,000 individuals were "urged to evacuate swiftly." The operation to deactivate the bomb began late Friday and lasted until around 11:30 a.m. Saturday. No one was injured in the operation.

Bombs left over from World War II are discovered from time to time in Hong Kong. The city was occupied by Japanese forces during the war, when it became a base for the Japanese military and shipping. The United States, along with other Allied forces, targeted Hong Kong in air raids to disrupt Japanese supply lines and infrastructure.
"Bombs from the war have triggered evacuations and emergency measures around the globe in recent months," reports CBS News: Earlier this month, a 500-pound bomb was discovered in Slovakia's capital during construction work, prompting evacuations. In August, large parts of Dresden, Germany, were evacuated so experts could defuse an unexploded World War II bomb found during clearance work for a collapsed bridge. In June, over 20,000 people were evacuated from Cologne after three unexploded U.S. bombs from the war were found... In March, a World War II bomb was found near the tracks of Paris' Gare du Nord station. In February, more than 170 bombs were found near a children's playground in northern England. And in October 2024, a World War II bomb exploded at a Japanese airport.

Governments worldwide are implementing heat protection laws as 2.4 billion workers face extreme temperature exposure and 19,000 die annually from heat-related workplace injuries, according to a World Health Organization and World Meteorological Organization report.

Japan imposed $3,400 fines for employers failing to provide cooling measures when wet-bulb temperatures reach 28C. Singapore mandated hourly temperature sensors at large outdoor sites and requires 15-minute breaks every hour at 33C wet-bulb readings. Southern European nations ordered afternoon work stoppages this summer when temperatures exceeded 115F across Greece, Italy and Spain.

The United States lacks federal heat standards; only California, Colorado, Maryland, Minnesota, Nevada, Oregon and Washington have state-level protections. Boston passed requirements for heat illness prevention plans on city projects. Enforcement remains inconsistent -- Singapore inspectors found nearly one-third of 70 sites violated the 2023 law. Texas and Florida prohibit local governments from mandating rest and water breaks.

The oldest person living in Japan is 114 years old, reports the BBC. But "The number of people in Japan aged 100 or older has risen to a record high of nearly 100,000, its government has announced." Setting a new record for the 55th year in a row, the number of centenarians in Japan was 99,763 as of September, the health ministry said on Friday. Of that total, women accounted for an overwhelming 88%... Health minister Takamaro Fukoka congratulated the 87,784 female and 11,979 male centenarians on their longevity and expressed his "gratitude for their many years of contributions to the development of society"....

The higher life expectancy is mainly attributed to fewer deaths from heart disease and common forms of cancer, in particular breast and prostate cancer. Japan has low rates of obesity, a major contributing factor to both diseases, thanks to diets low in red meat and high in fish and vegetables. The obesity rate is particularly low for women, which could go some way to explaining why Japanese women have a much higher life expectancy than their male counterparts... But it's not just diet. Japanese people tend to stay active into later life, walking and using public transport more than elderly people in the US and Europe...

However, several studies have cast doubt on the validity of global centenarian numbers, suggesting data errors, unreliable public records and missing birth certificates may account for elevated figures. A government audit of family registries in Japan in 2010 uncovered more than 230,000 people listed as being aged 100 or older who were unaccounted for, some having in fact died decades previously. The miscounting was attributed to patchy record-keeping and suspicions that some families may have tried to hide the deaths of elderly relatives in order to claim their pensions.

Physicists have confirmed Stephen Hawking's 1971 black hole area theorem with near-absolute certainty, thanks to gravitational waves from an exceptionally loud black hole collision detected by upgraded LIGO instruments. New Scientist reports: Hawking proposed his black hole area theorem in 1971, which states that when two black holes merge, the resulting black hole's event horizon -- the boundary beyond which not even light can escape the clutches of a black hole -- cannot have an area smaller than the sum of the two original black holes. The theorem echoes the second law of thermodynamics, which states that the entropy, or disorder within an object, never decreases.

Black hole mergers warp the fabric of the universe, producing tiny fluctuations in space-time known as gravitational waves, which cross the universe at the speed of light. Five gravitational wave observatories on Earth hunt for waves 10,000 times smaller than the nucleus of an atom. They include the two US-based detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) plus the Virgo detector in Italy, KAGRA in Japan and GEO600 in Germany, operated by an international collaboration known as LIGO-Virgo-KAGRA (LVK).

The recent collision, named GW250114, was almost identical to the one that created the first gravitational waves ever observed in 2015. Both involved black holes with masses between 30 and 40 times the mass of our sun and took place about 1.3 billion light years away. This time, the upgraded LIGO detectors had three times the sensitivity they had in 2015, so they were able to capture waves emanating from the collision in unprecedented detail. This allowed researchers to verify Hawking's theorem by calculating that the area of the event horizon was indeed larger after the merger. The findings have been published in the journal Physical Review Letters.

An anonymous reader quotes a report from Wired: The United States has emerged as the largest investor in commercial spyware -- a global industry that has enabled the covert surveillance of journalists, human rights defenders, politicians, diplomats, and others, posing grave threats to human rights and national security. In 2024, 20 new US-based spyware investors were identified, bringing the total number of American backers of this technology to 31. This growth has largely outpaced other major investing countries such as Israel, Italy, and the United Kingdom, according to a new report published today by the Atlantic Council.

The study surveyed 561 entities across 46 countries between 1992 and 2024, identifying 34 new investors. This brings the total to 128, up from 94 in the dataset published last year. The number of identified investors in the EU Single Market, plus Switzerland, stands at 31, with Italy -- a key spyware hub -- accounting for the largest share at 12. Investors based in Israel number 26. US-based investors include major hedge funds D.E. Shaw & Co. and Millennium Management, prominent trading firm Jane Street, and mainstream financial-services company Ameriprise Financial -- all of which, according to the Atlantic Council, have channeled funds to Israeli lawful-interception software provider Cognyte, a company allegedly linked to human rights abuses in Azerbaijan and Indonesia, among others. [...]

Apart from focusing on investment, the Atlantic Council notes that the global spyware market is "growing and evolving," with its dataset expanded to include four new vendors, seven new resellers or brokers, 10 new suppliers, and 55 new individuals linked to the industry. Newly identified vendors include Israel's Bindecy and Italy's SIO. [...] The study reveals the addition of three new countries linked to spyware activity -- Japan, Malaysia, and Panama. Japan in particular is a signatory to international efforts to curb spyware abuse, including the Joint Statement on Efforts to Counter the Proliferation and Misuse of Commercial Spyware and the Pall Mall Process Code of Practice for States. The Atlantic Council's Jen Roberts, who also worked on the report, urged expanding Executive Order 14105 to also include spyware. He also emphasized preserving Executive Order 14093, noting that U.S. purchasing power is a key lever in shaping and constraining the global spyware market. "US purchasing power is a significant tool in shaping and constraining the global market for spyware," said Roberts.

"A U.S.-based nuclear fusion developer wants to deploy a reactor in Japan in the late 2030s or early 2040s," reports Bloomberg, "in line with the Asian country's broader plans to adopt the potent, low-carbon energy source." Commonwealth Fusion Systems, which last week announced it raised $863 million from investors including Nvidia, has been in dialogue with Japanese government officials on the use of its technology, CEO Bob Mumgaard said in an interview in Tokyo on Wednesday... Several countries are eyeing the technology for its climate and energy security benefits but only some, like China, the U.S., Russia and South Korea have managed to crack the basics. Japan revised its national strategy in June to support fusion deployment and build a demonstration plant in the 2030s.
The article notes that Commonwealth "does not currently have any reactors in operation" — but that Mitsubishi this week invested in the company, in collaboration with a consortium of 12 Japanese companies. From Mitsubishi's announcement: The Japanese Consortium will acquire technical and commercial expertise in policy, regulatory, and the development, construction, operation, and maintenance of ARC [power plant] from CFS's commercialization projects in the United States. In addition, each consortium company will bring together its know-how and expertise and aspire to expedite the commercialization and industrialization of fusion energy power generation in Japan.

"According to a new study, wearing the right kind of perfume or cologne can enlarge your brain's gray matter," writes ScienceAlert Researchers from Kyoto University and the University of Tsukuba in Japan asked 28 women to wear a specific rose scent oil on their clothing for a month, with another 22 volunteers enlisted as controls who put on plain water instead. Magnetic resonance imaging ( MRI) scans showed boosts in the gray matter volume of the rose scent participants.

While an increase in brain volume doesn't necessarily translate into more thinking power, the findings could have implications for neurodegenerative conditions such as dementia. "This study is the first to show that continuous scent inhalation changes brain structure," write the researchers in their published paper. We've seen scents like this improve memory and cognitive performance, but here the team wanted to try a longer-term experiment to see how triggering our sense of smell might lead to measurable changes in brain structure...

It's difficult to pin down exactly what's causing this boost in gray matter. Another possibility raised by the researchers is that the rose scent is actually labeled as unpleasant by the brain, with the subsequent emotional regulation responsible for the PCC working harder and increasing in size. The researchers hope that the findings could be useful in the development of aromatherapies that boost mental health and brain plasticity...

The research was published in the Brain Research Bulletin.

By exploiting two-color beams, researchers "can generate ordered chains and lattices," reports ScienceDaily, "with tunable topology — potentially revolutionizing data storage, communications, and photonic processing." An internationally joint research group between Singapore and Japan has unveiled a blueprint for arranging exotic, knot-like patterns of light into repeatable crystals that extend across both space and time. The work lays out how to build and control "hopfion" lattices using structured beams.. three-dimensional topological textures whose internal "spin" patterns weave into closed, interlinked loops.

They have been observed or theorized in magnets and light fields, but previously they were mainly produced as isolated objects. The authors show how to assemble them into ordered arrays that repeat periodically, much like atoms in a crystal, only here the pattern repeats in time as well as in space. The key is a two-color, or bichromatic, light field whose electric vector traces a changing polarization state over time. By carefully superimposing beams with different spatial modes and opposite circular polarizations, the team defines a "pseudospin" that evolves in a controlled rhythm. When the two colors are set to a simple ratio, the field beats with a fixed period, creating a chain of hopfions that recur every cycle. Starting from this one-dimensional chain, the researchers then describe how to sculpt higher-order versions whose topological strength can be dialed up or down...

Topological textures like skyrmions have already reshaped ideas for dense, low-error data storage and signal routing. Extending that toolkit to hopfion crystals in light could unlock high-dimensional encoding schemes, resilient communications, atom trapping strategies, and new light-matter interactions. "The birth of space-time hopfion crystals," the authors write, opens a path to condensed, robust topological information processing across optical, terahertz, and microwave domains.

China has turned on the world's most sensitive neutrino detector after more than a decade of construction. The Register reports: The Jiangmen Underground Neutrino Experiment (JUNO) is buried 700 meters under a mountain and features a 20,000-tonne "liquid scintillator detector" that China's Academy of Science says is "housed at the center of a 44-meter-deep water pool." There's also a 35.4-meter-diameter acrylic sphere supported by a 41.1-meter-diameter stainless steel truss. All that stuff is surrounded by more than 45,000 photo-multiplier tubes (PMTs). The latter devices are super-sensitive light detectors. A liquid scintillator is a fluid that, when exposed to ionizing radiation, produces light. At JUNO, the liquid is 99.7 percent alkylbenzene, an ingredient found in detergents and refrigerants.

JUNO's designers hope that any neutrinos that pass through its giant tank bonk a hydrogen atom and produce just enough light that the detector array of PMTs can record their passing, producing data scientists can use to learn more about the particles. At this point, readers could sensibly ask how JUNO will catch any of these elusive particles. The answer lies in the facility's location -- a few tens of kilometers away from two nuclear power plants that produce neutrinos.

The Chinese Academy of Science's Journal of High Energy Physics says trials of JUNO succeeded, suggesting it will be able to help scientists understand why some neutrinos are heavier than others so we can begin to classify the different types of the particle -- a key goal for the facility. The Journal also reports that scientists from Japan, the United States, Europe, India, and South Korea, are either already using JUNO or plan experiments at the facility.

A central Japanese town wants to limit smartphone use for all its 69,000 residents to two hours a day, in a move that has sparked intense debate on device addiction. From a report: The proposal, believed to be the first of its kind in Japan, is currently being debated by lawmakers after being submitted by Toyoake municipal government in Aichi earlier this week. Toyoake's mayor said the proposal -- which only applies outside of work and study -- would not be strictly enforced, but rather was meant to "encourage" residents to better manage their screen time.

There will be no penalties for breaking the rule, which will be passed in October if approved by lawmakers. "The two hour limit... is merely a guideline... to encourage citizens," Toyoake Mayor Masafumi Koki said in a statement. "This does not mean the city will limit its residents' rights or impose duties," he said.

Japan has launched its first entirely homegrown quantum computer, built with domestic superconducting qubits and components, and running on the country's own open-source software toolchain, OQTOPUS. "The system is now ready to take on workloads from its base at the University of Osaka's Center for Quantum Information and Quantum Biology (QIQB)," reports LiveScience. From the report: The system uses a quantum chip with superconducting qubits -- quantum bits derived from metals that exhibit zero electrical resistance when cooled to temperatures close to absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius). The quantum processing unit (QPU) was developed at the Japanese research institute RIKEN. Other components that make up the "chandelier" -- the main body of the quantum computer -- include the chip package, delivered by Seiken, the magnetic shield, infrared filters, bandpass filters, a low-noise amplifier and various cables.

These are all housed in a dilution refrigerator (a specialized cryogenic device that cools the quantum computing components) to allow for those extremely low temperatures. It also comes alongside a pulse tube refrigerator (which again cools various components in use), controllers and a low-noise power source. OQTOPUS, meanwhile, is a collection of open-source tools that include everything required to run quantum programs. It includes the core engine and cloud module, as well as graphical user interface (GUI) elements, and is designed to be built on top of a QPU and quantum control hardware.

Two of Japan's largest media groups are suing AI search engine Perplexity over alleged copyright infringement, joining a growing list of news publishers taking legal action against AI companies using their content. FT: Japanese media group Nikkei, which owns the Financial Times, and the Asahi Shimbun newspaper said in statements on Tuesday that they had jointly filed a lawsuit in Tokyo. The groups join a number of Western media companies taking legal action against Perplexity, which provides answers to questions with sources and citations, using large language models (LLMs) from platforms such as OpenAI and Anthropic.

The Japanese news providers claim Perplexity has, without permission, "copied and stored article content from the servers of Nikkei and Asahi" and ignored a "technical measure" designed to prevent this from happening. They claim that Perplexity's answers have given incorrect information attributed to the newspapers' articles, which "severely damages the credibility of newspaper companies."

Living through extreme heat waves can accelerate your rate of aging, according to research published Monday. From a report: Scientists analyzed 15 years' worth of health data from nearly 25,000 adults in Taiwan and found that two years of exposure to heat waves could speed up a person's so-called biological aging by eight to 12 extra days. It may not sound like a lot, but this number builds over time, said Cui Guo, an assistant professor at the University of Hong Kong who led the study, which was published Monday in the journal Nature Climate Change.

"This small number actually matters," she said. "This was a study of a two-year exposure, but we know heat waves have actually been occurring for decades." The research comes as human-induced climate change is making heat waves more intense and long-lasting. The West Coast of the United States is suffering from sweltering temperatures while Iran is experiencing searing heat. Record-breaking temperatures punished Europe, Japan and Korea earlier this month. France recently experienced its second heat wave of the summer, sparking a national debate over air-conditioning.

A 22-year-old Oregon man has been charged with operating one of the most powerful botnets ever recorded. The network, known as Rapper Bot, launched over 370,000 DDoS attacks worldwide, including against X, DeepSeek, U.S. tech firms, and even Defense Department systems. It was allegedly operated by Ethan Foltz of Eugene, Oregon. The Wall Street Journal reports: Foltz faces a maximum of 10 years in prison on a charge of abetting computer intrusions, the Justice Department said in a news release. Rapper Bot was made up of tens of thousands of hacked devices and was capable of flooding victims' websites with enough junk internet traffic to knock them offline, an attack known as a distributed denial of service, or DDoS.

In February, the networking company Nokia measured a Rapper Bot attack against a gaming platform at 6.5 trillion bits per second, well above the several hundred million bits a second of the average high-speed internet connection. "This would place Rapper Bot among the most powerful DDoS botnets to have ever existed," said a criminal complaint that the prosecutors filed Tuesday in a federal court in Alaska. Investigators said Rapper Bot's attacks were so powerful that they were able to overwhelm all but the most robust networks.

Foltz allegedly rented out Rapper Bot to paying customers, including gambling website operators who would use the network in extortion attempts, according to the complaint. The botnet was used to launch more than 370,000 attacks in 80 countries, including China, Japan and the U.S., prosecutors said. It launched its attacks from hacked routers, digital video recorders and cameras, not from computers. [...] "At its height, it mobilized tens of thousands of devices, many with no prior role in DDoS," said Jerome Meyer, a researcher with Nokia's Deepfield network-analysis division. "Taking it down removes a major source of the largest attacks we see."

US tech stocks sold off as warnings that the hype surrounding AI could be overdone hit some of the year's best-performing shares. From a report: Nvidia, the chips group that has surged to become the world's first $4tn company on the back of AI, fell 3.5 per cent on Tuesday, while software group Palantir dropped 9.4 per cent and chip designer Arm shed 5 per cent.

The tech-heavy Nasdaq Composite closed down 1.4 per cent, the biggest one-day drop for the index since August 1. The blue-chip S&P 500 fell 0.7 per cent. European and Asian markets largely followed Wall Street lower on Wednesday. [...] Japan's Nikkei 225 index fell 1.5 per cent and South Korea's Kospi slipped 0.6 per cent. Futures price indicated moderate declines when Wall Street opens.

Traders pinned some of the declines in the US on a critical report on Monday authored by a branch of the Massachusetts Institute of Technology. Researchers said "95 per cent of organisations are getting zero return" from their investments in generative AI, the technology that has sent US stocks soaring to record highs in recent months.

Last week saw the 80th anniversary of a turning point in World War II: the day America dropped an atomic bomb on Hiroshima.

"Twelve men were on that flight..." remembers the online magazine Mental Floss, adding "Almost all had something to say after the war." The group was segregated from the rest of the military and trained in secret. Even those in the group only knew as much as they needed to know in order to perform their duties. The group deployed to Tinian in 1945 with 15 B-29 bombers, flight crews, ground crews, and other personnel, a total of about 1770 men. The mission to drop the atomic bomb on Hiroshima, Japan (special mission 13) involved seven planes, but the one we remember was the Enola Gay.

Air Force captain Theodore "Dutch" Van Kirk did not know the destructive force of the nuclear bomb before Hiroshima. He was 24 years old at that time, a veteran of 58 missions in North Africa. Paul Tibbets told him this mission would shorten or end the war, but Van Kirk had heard that line before. Hiroshima made him a believer. Van Kirk felt the bombing of Hiroshima was worth the price in that it ended the war before the invasion of Japan, which promised to be devastating to both sides. " I honestly believe the use of the atomic bomb saved lives in the long run. There were a lot of lives saved. Most of the lives saved were Japanese."

In 2005, Van Kirk came as close as he ever got to regret. "I pray no man will have to witness that sight again. Such a terrible waste, such a loss of life..."
Many of the other crewmembers also felt the bomb ultimately saved lives.

The Washington Post has also published a new oral history of the flight after it took off from Tinian Island. The oral history was assembled for a new book published this week titled The Devil Reached Toward the Sky: An Oral History of the Making and Unleashing of the Atomic Bomb.. Col. Paul W. Tibbets, lead pilot of the Enola Gay: We were only eight minutes off the ground when Capt. William S. "Deak" Parsons and Lt. Morris R. Jeppson lowered themselves into the bomb bay to insert a slug of uranium and the conventional explosive charge into the core of the strange-looking weapon. I wondered why we were calling it ''Little Boy." Little Boy was 28 inches in diameter and 12 feet long. Its weight was a little more than 9,000 pounds. With its coat of dull gunmetal paint, it was an ugly monster...

Lt. Morris R. Jeppson, crew member of the Enola Gay: Parsons was second-in-command of the military in the Manhattan Project. The Little Boy weapon was Parsons's design. He was greatly concerned that B-29s loaded with conventional bombs were crashing at the ends of runways on Tinian during takeoff and that such an event could cause the U-235 projectile in the gun of Little Boy to fly down the barrel and into the U-235 target. This could have caused a low-level nuclear explosion on Tinian...

Jeppson: On his own, Parsons decided that he would go on the Hiroshima mission and that he would load the gun after the Enola Gay was well away from Tinian.

Tibbets: That way, if we crashed, we would lose only the airplane and crew, himself included... Jeppson held the flashlight while Parsons struggled with the mechanism of the bomb, inserting the explosive charge that would send one block of uranium flying into the other to set off the instant chain reaction that would create the atomic explosion.
The navigator on one of the other six planes on the mission remember that watching the mushroom cloud, "There was almost complete silence on the flight deck. It was evident the city of Hiroshima was destroyed."

And the Enola Gay's copilot later remembered thinking: "My God, what have we done?"

hackingbear shares a report from CNN: Taiwanese authorities have detained three current and former employees of the world's largest chip manufacturer, Taiwan Semiconductor Manufacturing Company (TSMC), for allegedly stealing trade secrets [and taking them to Japanese company Tokyo Electrons], prosecutors said Tuesday. Law enforcement officers questioned several suspects and witnesses late last month. They searched their homes and detained three of them over "serious suspicions of violating national security laws," the intellectual property branch of the Taiwan High Prosecutors Office said on Tuesday. After an internal investigation, the major Taiwanese exporter raised suspicions with authorities that its "core technologies" may have been illegally accessed by former and current staffers.

Nikkei Asia first reported on Tuesday that TSMC had fired staffers suspected of illegally obtaining business secrets related to the manufacturing technology for the company's 2-nanometer chip, the most advanced processor in the semiconductor industry that is expected to go into mass production this year. Taiwanese local media reported that a former TSMC employee now works at top chip manufacturing equipment supplier Tokyo Electron Ltd., and that the Japanese firm's Taiwan office was raided by investigators. On Thursday, Tokyo Electron confirmed it had dismissed an employee of its Taiwan subsidiary who was involved in the case, and said the company was cooperating with authorities. "As of now, based upon the findings of our internal investigation we have not confirmed any evidence of the respective confidential information shared to any third parties," it said in a statement.

Despite dwindling global market share, retreat from key regions like Europe, and halting in-house production, Sony insists its Xperia smartphone line remains "very important" to its business. 9to5Google reports: During Sony's latest financial results presentation this week, Sony CFO Lin Tao addressed the state of its Xperia smartphone brand, saying that Xperia is part of "a very important business for us" as reported by CNET Japan (translated). Tao said that "communication technology is a very important technology that Sony has cultivated for a long time. We also want to continue to value our smartphone business." Though adding that "communication technology is used in areas other than smartphones."
