An out-of-control Chinese rocket plunged out of orbit and reentered Earth's atmosphere in the Indian Ocean (just west of the Maldives), reports CNN, citing China's space agency: Most of the rocket was "destroyed" on reentry to the atmosphere, the space agency said. The rocket, which is about 108 feet tall and weighs nearly 40,000 pounds, had launched a piece of a new Chinese space station into orbit on April 29.

After its fuel was spent, the rocket had been left to hurtle through space uncontrolled until Earth's gravity dragged it back to the ground.

Generally, the international space community tries to avoid such scenarios. Most rockets used to lift satellites and other objects into space conduct more controlled reentries that aim for the ocean, or they're left in so-called "graveyard" orbits that keep them in space for decades or centuries. But the Long March rocket is designed in a way that "leaves these big stages in low orbit," said Jonathan McDowell, an astrophysicist at the Astrophysics Center at Harvard University.

In this case, it was impossible to be certain exactly when or where the booster would land. The European Space Agency had predicted a "risk zone" that encompassed "any portion of Earth's surface between about 41.5N and 41.5S latitude" — which included virtually all of the Americas south of New York, all of Africa and Australia, parts of Asia south of Japan and Europe's Spain, Portugal, Italy and Greece. The threat to populated areas of land was not negligible, but fortunately the vast majority of Earth's surface area is consumed by oceans...

The rocket is one of the largest objects in recent memory to strike the Earth after falling out of orbit, following a 2018 incident in which a piece of a Chinese space lab broke up over the Pacific Ocean and the 2020 reentry of an 18-metric-ton Long March 5B rocket [also launched by China].

An anonymous reader quotes a report from Science Magazine: Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world's worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. "It's like the embers in a barbecue pit," says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own -- or require extraordinary interventions to avert another accident.

Sensors are tracking a rising number of neutrons, a signal of fission, streaming from one inaccessible room, Anatolii Doroshenko of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv, Ukraine, reported last week during discussions about dismantling the reactor. "There are many uncertainties," says ISPNPP's Maxim Saveliev. "But we can't rule out the possibility of [an] accident." The neutron counts are rising slowly, Saveliev says, suggesting managers still have a few years to figure out how to stifle the threat. Any remedy he and his colleagues come up with will be of keen interest to Japan, which is coping with the aftermath of its own nuclear disaster 10 years ago at Fukushima, Hyatt notes. "It's a similar magnitude of hazard."

Japan is opening its first gym for esports in Tokyo, a space for both amateur and experienced gamers to train and get professional coaching, according to Japan Today. From a report: The competitive gaming space, which is set to open on May 19 and will be known as "Esports Gym," will include a lounge and gaming PCs outfitted with some of Japan's most popular games, including Valorant and League of Legends. Gamers can book a three-hour time slot at one of the PCs for about $13 or opt for a monthly membership starting at $50, which allows daily access to the gaming PCs as well as optional coaching sessions that can be added on for about $25 an hour. Esports Gym, which is jointly operated by private transit company Tokyo Metro and esports education company Gecipe, will welcome experienced gamers as well as those who are new to gaming PCs or don't understand the game rules, according to the website.

A union leader at Amazon's Japan offices has filed a lawsuit against the company for wrongful termination, alleging he was unfairly targeted for his organizing activity. From a report: Masafumi Ito, who worked at the tech giant as a salesperson for more than seven years, was fired last month after being placed on a series of performance improvement plans, or PIPs, which he alleges were a ruse to force him out of the company. Ito is seeking to have his job reinstated and force Amazon to pay his lost wages. "I joined Amazon because I love the company. I want to return to work and continue to contribute," Ito said at a press conference in Tokyo earlier this week. "I brought this case because I want to change the work environment where people are suddenly fired for unfair reasons. My colleagues cannot work safely under such an environment."

Ito and other members of the Amazon Japan Union -- who organized as part of the Tokyo Managers' Union (MU) in 2015 -- say the company weaponizes PIPs to arbitrarily dismiss employees, particularly those who challenge its relentless work culture. Amazon argues the plans help staff develop and learn, but their use has been controversial at the tech giant in Tokyo, as well as the U.S., for years. Ito's case, which has received significant attention in Japan, will now test whether Amazon's practices can survive in the country. Ito's role at Amazon was to bring more electronics stores onto the company's shopping platform and encourage them to use Amazon Prime. He said he performed well, but managers still subjected him to a series of PIPs and disciplinary actions over the past few years. Ito was finally fired in March, after he failed to meet the requirements of his latest evaluation, and managers told him he showed no desire to improve.

NASA has tweeted a video showing the arrival of four astronauts from three countries on the International Space Station early Satuday morning.

CNN describes the significance to their arrival — and what the astronauts will do during their six-month stay in space: This mission, dubbed Crew-2, marks the third-ever crewed flight for Elon Musk's company and the first to make use of a previously flown, privately-owned rocket booster and spacecraft... On Saturday morning, the capsule slowly aligned itself and moved in to dock directly with one of the space station's ports.

The crew consists of NASA astronauts Shane Kimbrough and Megan McArthur, Thomas Pesquet of the European Space Agency, and Akihiko Hoshide with Japan's JAXA space agency.

A prime focus of the astronauts' mission will be research with "tissue chips," or "small models of human organs containing multiple cell types that behave much the same as they do in the body" and that NASA hopes will advance the development of drugs and vaccines, according to the space agency. That work will build on years of studying biological and other scientific phenomena aboard the ISS, where the microgravity environment can give scientists a better fundamental understanding of how something works.

Kimbrough, McArthur, Pesquet, and Hoshide joined seven astronauts already on board the station, four of whom arrived on a different SpaceX Crew Dragon capsule in November. That brings the space station's current total of personnel to 11 — one of the largest crews the ISS has ever hosted. But that number will quickly drop back down to seven when four of the astronauts who'd been on board hitch a ride home from the station on April 28.

Honda will end production of combustion motors by 2040 as it embarks on a wide-reaching drive to achieve total carbon neutrality by 2050 and to advance the development of its zero-emission powertrain solutions. AutoCar reports: Company president Toshihiro Mibe detailed a series of ambitious objectives at a press conference in Japan today, where he solidified the brand's commitment to leading "advancements which will be made in the areas of mobility, the power unit, energy and robotics." By 2050, Honda aims to achieve carbon neutrality across "all products and corporate activities," which will see it shift focus predominantly to developing environmentally friendly powertrains and overhauling its supply chain to ensure products are "made from 100% sustainable materials."

The brand had already confirmed it would offer exclusively electrified passenger cars in Europe by the end of 2022, but is now solidifying its global electrification strategy for the coming years. By 2030, Honda plans for 40% of its sales to be pure-electric or fuel cell (FCEV) vehicles, rising to 80% by 2035 and 100% by 2040. Specific goals for the European market have yet to be fully detailed, but a strategic partnership with General Motors will accelerate electrification efforts in North America, while a total of 10 new Honda-badged EVs will be launched in the Chinese market "within five years" - the first of which will be the production version of the e:prototype shown at Shanghai last week. Honda has also confirmed that in the second half of the decade, it will launch a range of EVs atop its new 'e:Architecture' platform. The models will arrive in the US first, before being rolled out to other regions, likely including Europe.

Japan's central government has declared a third state of emergency due to the COVID-19 pandemic with new restrictions imposed in Tokyo, Osaka, Kyoto and Hyogo prefectures. Local leaders requested the move as they face a sharp rise in new coronavirus cases. From a report: The declaration comes as Tokyo prepares to host the Summer Olympics, slated to begin in July, and just before Japan enters one of its biggest holiday seasons, Golden Week, in late April. The emergency measures stop short of a full lockdown, but they impose limits on restaurants and other businesses. The strictest rules will apply to places that sell alcohol or offer karaoke. They'll be asked to close entirely, while many other establishments will close at 8 p.m. The new policies, which carry fines but largely rely on voluntary compliance, go into effect on Sunday and will run through at least May 11. Nationwide, Japan is seeing spikes in new cases and hospitalizations, both of which are soaring toward the record heights that were seen at the start of 2021. Some 5,452 people tested positive for the coronavirus on Thursday, according to the Ministry of Health, Labour and Welfare.

A group of hackers executed a ransomware attack on Hoya, marking the second successful attack suffered by the Japanese firm in two years. From a report: "We can confirm that Hoya Vision Care US has experienced a cyberattack. Based on our initial forensics, the disruption appears to have been limited to our United States systems," a Hoya spokesperson said. "After identifying the threat, we quickly took action to contain it and contacted law enforcement. The company has engaged external experts to determine the nature and scope of this event. We will provide updates as more information becomes available." Hoya, named after the West Tokyo neighborhood where it was founded in 1941, is a glassmaker with about 37,000 employees worldwide and about $5 billion in annual revenue. The company gets last year 65% of its sales from contact lenses and glasses, while the rest comes Information technology devices and services such glass substrate used in the manufacturing of semiconductors and hard disk drives, according to 2020 company's report. The hacker group called Astro Team said on its blog last week that it targeted Hoya servers and stole about 300 gigabytes of confidential corporate data including finance, production, email messages, passwords and safety reports. In 2019, Hoya suffered a major cyberattack, infectong over 100 computers and forcing the company to shut down its factories for three days.

The UK government will look into the national security implications of U.S. group Nvidia's purchase of British chip designer ARM, it said on Monday, putting a question mark over the $40 billion deal. From a report: Digital minister Oliver Dowden said on Monday he had issued a so-called "intervention notice" over the sale of ARM by Japan's SoftBank to Nvidia. "As a next step and to help me gather the relevant information, the UK's independent competition authority will now prepare a report on the implications of the transaction, which will help inform any further decisions," he said. Nvidia said it did not believe the deal posed any material national security issues.

The Japanese government has been forced to quickly retire an animated character it had hoped would win support for its decision this week to release more than 1m tonnes of contaminated water from the Fukushima Daiichi nuclear power plant into the sea. From a report: Although the water will be treated before being discharged, it will still contain tritium, a radioactive hydrogen isotope represented on a government website by a cute fish-like creature with rosy cheeks. The character's appearance in an online flyer and video on the reconstruction agency's website angered Fukushima residents. "It seems the government's desire to release the water into the sea takes priority over everything," Katsuo Watanabe, an 82-year-old Fukushima fisher, told the Kyodo news agency. "The gap between the gravity of the problems we face and the levity of the character is huge."

Riken Komatsu, a local writer, tweeted: "If the government thinks it can get the general public to understand just by creating a cute character, it is making a mockery of risk communication." Social media users named the character Tritium-kun -- or Little Mr Tritium -- an apparent reference to Pluto-kun, who appeared in the mid-1990s to soften the image of plutonium on behalf of Japan's nuclear industry. The reconstruction agency, which oversees recovery efforts in the region destroyed by the March 2011 earthquake, tsunami and nuclear meltdown, removed the promotional material on Wednesday, a day after it first appeared. Experts say tritium is harmful to humans only in large doses, and that with dilution the treated water poses no scientifically detectable risk.

According to the Associated Press, Japan's government decided it will start releasing treated radioactive water accumulated at the crippled Fukushima nuclear plant into the Pacific Ocean in two years. From the report: Under the basic plan adopted Tuesday by the ministers, Tokyo Electric Power Company Holdings, also known as TEPCO, will start releasing the water in about two years after building a facility and compiling release plans adhering to safety requirements. It said the disposal of the water cannot be postponed further and is necessary to improve the environment surrounding the plant so residents can live there safely. TEPCO says its water storage capacity of 1.37 million tons will be full around fall of 2022. Also, the area now filled with storage tanks will have to be freed up for building new facilities needed for removing melted fuel debris from inside the reactors and for other decommissioning work that's expected to start in coming years.

In the decade since the tsunami disaster, water meant to cool the nuclear material has constantly escaped from the damaged primary containment vessels into the basements of the reactor buildings. To make up for the loss, more water has been pumped into the reactors to continue to cool the melted fuel. Water is also pumped out and treated, part of which is recycled as cooling water, and the remainder stored in 1,020 tanks now holding 1.25 million tons of radioactive water. Those tanks that occupy a large space at the plant interfere with the safe and steady progress of the decommissioning, Economy and Industry Minister Hiroshi Kajiyama said. The tanks also could be damaged and leak in case of another powerful earthquake or tsunami, the report said.

Releasing the water to the ocean was described as the most realistic method by a government panel that for nearly seven years had discussed how to dispose of the water. The report it prepared last year mentioned evaporation as a less desirable option. About 70% of the water in the tanks is contaminated beyond discharge limits but will be filtered again and diluted with seawater before it is released, the report says. According to a preliminary estimate, gradual releases of water will take more than 30 years but will be completed before the plant is fully decommissioned. Japan will abide by international rules for a release, obtain support from the International Atomic Energy Agency and others, and ensure disclosure of data and transparency to gain understanding of the international community, the report said. China blasted the Japanese government for being "extremely irresponsible," and warned that it might take action. "The Japanese side has yet to exhaust all avenues of measures, disregarded domestic and external opposition, has decided to unilaterally release the Fukushima plant's nuclear waste water without full consultation with its neighboring countries and the international community," the foreign ministry statement said. "This action is extremely irresponsible and will pose serious harm to the health and safety of the people in neighboring countries and the international community."

South Korea also isn't happy with Japan's decision. "The government expresses strong regret over the Japanese government's decision to release contaminated water from the Fukushima nuclear plant into the ocean," said Koo Yoon-cheol, head of South Korea's Office for Government Policy Coordination.

Nvidia said it's offering the company's first server microprocessors, extending a push into Intel's most lucrative market with a chip aimed at handling the most complicated computing work. Intel shares fell more than 2% on the news. From a report: The graphics chipmaker has designed a central processing unit, or CPU, based on technology from Arm, a company it's trying to acquire from Japan's SoftBank Group. The Swiss National Supercomputing Centre and U.S. Department of Energy's Los Alamos National Laboratory will be the first to use the chips in their computers, Nvidia said Monday at an online event. Nvidia has focused mainly on graphics processing units, or GPUs, which are used to power video games and data-heavy computing tasks in data centers. CPUs, by contrast, are a type of chip that's more of a generalist and can do basic tasks like running operating systems. Expanding into this product category opens up more revenue opportunities for Nvidia.

Founder and Chief Executive Officer Jensen Huang has made Nvidia the most valuable U.S. chipmaker by delivering on his promise to give graphics chips a major role in the explosion in cloud computing. Data center revenue contributes about 40% of the company's sales, up from less than 7% just five years ago. Intel still has more than 90% of the market in server processors, which can sell for more than $10,000 each. The CPU, named Grace after the late pioneering computer scientist Grace Hopper, is designed to work closely with Nvidia graphics chips to better handle new computing problems that will come with a trillion parameters. Systems working with the new chip will be 10 times faster than those currently using a combination of Nvidia graphics chips and Intel CPUs. The new product will be available at the beginning of 2023, Nvidia said.

New submitter evaverdeazul shared this report from Japan Today: The Japanese government is poised to release treated radioactive water accumulated at the crippled Fukushima nuclear plant into the sea despite opposition from fishermen, sources familiar with the matter said Friday. It will hold a meeting of related ministers as early as Tuesday to formally decide on the plan, a major development following over seven years of discussions on how to discharge the water used to cool down melted fuel at the Fukushima Daiichi plant.

The treated water containing radioactive tritium, a byproduct of nuclear reactors, is said to pose little risk to human health because even if one drinks the water, so long as the tritium concentration is low, the amounts of tritium would not accumulate in the body and would soon be excreted. There is also no risk of external exposure even if the water comes in contact with skin. Still, concerns remain among Japan's fisheries industry and consumers as well as neighboring countries such as South Korea and China.

The government has said it cannot continue postponing a decision on the disposal issue, given that the storage capacity of water tanks at the Fukushima complex is expected to run out as early as fall next year. It asserts that space needs to be secured on the premises, such as for keeping melted fuel debris that will be extracted from the damaged reactors, to move forward with the decades-long process of scrapping the complex.

Plant operator Tokyo Electric Power Company Holdings Inc (TEPCO) says it will take around two years for the discharge to start.

Cosmic rays are causing an estimated 30,000 to 40,000 malfunctions in domestic network communication devices in Japan every year, a Japanese telecom giant found recently. From a report: Most so-called "soft errors," or temporary malfunctions, in the network hardware of Nippon Telegraph and Telephone Corp. are automatically corrected via safety devices, but experts said in some cases they may have led to disruptions. It is the first time the actual scale of soft errors in domestic information infrastructures has become evident. Soft errors occur when the data in an electronic device is corrupted after neutrons, produced when cosmic rays hit oxygen and nitrogen in the earth's atmosphere, collide with the semiconductors within the equipment. Cases of soft errors have increased as electronic devices with small and high-performance semiconductors have become more common. Temporary malfunctions have sometimes led to computers and phones freezing, and have been regarded as the cause of some plane accidents abroad. Masanori Hashimoto, professor at Osaka University's Graduate School of Information Science and Technology and an expert in soft errors, said the malfunctions have actually affected other network communication devices and electrical machineries at factories in and outside Japan.

Physicist Isamu Akasaki, a co-winner of the 2014 Nobel Prize in physics for inventing the world's first efficient blue light-emitting diodes, has died, Meijo University said Friday. He was 92. The Japan Times reports: Akasaki, born in Kagoshima Prefecture, graduated from Kyoto University in 1952 before working at Matsushita Electric Industrial Co., now Panasonic Corp. He started working at Nagoya University as a professor in 1981 and was later given an honorary title. In 2014, he shared the Nobel Prize with physicist Hiroshi Amano, professor at the university, and Japan-born American Shuji Nakamura, professor at the University of California, Santa Barbara.

Akasaki, when he was a professor at Nagoya University, worked with Amano to produce gallium nitride crystals, and succeeded in 1989 in creating the world's first blue LED. Akasaki was honored in 1997 by the Japanese government with the Medal with Purple Ribbon, an honor bestowed on those who have made contributions to academic and artistic developments.

An anonymous reader quotes a report from the BBC: The cherry blossom season, Japan's traditional sign of spring, peaked at the earliest date since records began 1,200 years ago, research shows. The 2021 season in the city of Kyoto peaked on 26 March, according to data collected by Osaka University. Increasingly early flowerings in recent decades are likely to be as a result of climate change, scientists say. The records from Kyoto go back to 812 AD in imperial court documents and diaries. The previous record there was set in 1409, when the season reached its peak on March 27.

"In Kyoto, records of the timing of celebrations of cherry blossom festivals going back to the 9th Century reconstruct the past climate and demonstrate the local increase in temperature associated with global warming and urbanization," according to an earlier paper published in the scientific journal Biological Conservation. Since about 1800, the data suggest the peak date in Kyoto has gradually been moving back from mid-April towards the beginning of the month. This year, the season began in Hiroshima on March 11, eight days earlier than the previous record, which was set in 2004, according to Japan Forward.

For 30 years David E. Sanger has been covering foreign policy and nuclear proliferation for The New York Times — twice working on Pulitzer Prize-winning teams. But now as American and Chinese officials meet in Alaska, Sanger argues that China's power doesn't come from weapons — nuclear or otherwise: Instead, it arises from their expanding economic might and how they use their government-subsidized technology to wire nations be it Latin America or the Middle East, Africa or Eastern Europe, with 5G wireless networks intended to tie them ever closer to Beijing. It comes from the undersea cables they are spooling around the world so that those networks run on Chinese-owned circuits. Ultimately, it will come from how they use those networks to make other nations dependent on Chinese technology. Once that happens, the Chinese could export some of their authoritarianism by, for example, selling other nations facial recognition software that has enabled them to clamp down on dissent at home.

Which is why Jake Sullivan, Mr. Biden's national security adviser, who was with Secretary of State Antony J. Blinken for the meeting with their Chinese counterparts in Anchorage, warned in a series of writings in recent years that it could be a mistake to assume that China plans to prevail by directly taking on the United States military in the Pacific. "The central premises of this alternative approach would be that economic and technological power is fundamentally more important than traditional military power in establishing global leadership," he wrote, "and that a physical sphere of influence in East Asia is not a necessary precondition for sustaining such leadership...."

Part of the goal of the Alaska meeting was to convince the Chinese that the Biden administration is determined to compete with Beijing across the board to offer competitive technology, like semiconductor manufacturing and artificial intelligence, even if that means spending billions on government-led research and development projects, and new industrial partnerships with Europe, India, Japan and Australia... But it will take months, at best, to publish a broad new strategy, and it is unclear whether corporate America or major allies will get behind it.

After a year in which most people were stuck indoors, it should come as little surprise that streaming platforms skyrocketed in popularity over the past 12 months. For the first time ever, subscriptions to streaming services surpassed one billion, reaching 1.1 billion globally. From a report: At the same time, box office receipts plummeted because movie theaters across the world were closed for a significant part of 2020. Global ticket sales tapped out at $12 billion, with North America accounting for $2.2 billion of that haul. Though the circumstances aren't comparable, worldwide box office receipts totaled $42.5 billion in 2019, with $11.4 billion coming from domestic theaters. Still, it marks a 72% year-over-year decline. These statistics come from the Motion Pictures Association's annual theme report, which is conducted by the entertainment industry trade group and intends to analyze how film, television and streaming content performs yearly.

The 2020 study covers a year that was overshadowed by the coronavirus pandemic, making some of the data understandably skewed and difficult to compare box office totals between countries. In Asian countries, particularly in China, the box office has already returned to pre-pandemic levels. That hasn't been the case in the U.S. and Canada, where new movies are few and far between and audiences are returning to theaters at a glacial pace. Outside of North America, the top three box office markets were China ($3 billion), Japan ($1.3 billion), and France ($500 million). Combined, the global theatrical business and home and mobile entertainment market totaled $80.8 billion in revenues in 2020, shrinking by 18% from the $98.3 billion amassed last year. The success of digital home entertainment, which grew 23% to $68.8 billion, helped offset the depleted theatrical box office numbers. In the U.S., subscriptions reached 308.6 million, representing a 32% increase from 2019.

A two-armed robot is helping to prepare soba noodles at an eatery at JR Kaihimmakuhari Station in this Chiba city's Mihama Ward (in Japan), capably boiling the noodles in a strainer, rinsing them and then dipping them in iced water. From a report: The Sobaichi Perie Kaihimmakuhari eatery implemented a collaborative cooking system, with the robot cooking the food and employees adding the dipping sauce or soup and toppings. It is apparently the first time for the cooking robot to be introduced in an actual restaurant setting. Soba stands at railway stations usually have to deal with a constant stream of customers and work under time pressure, resulting in a chronic shortage of human resources. [...] The robot fetches soba noodles from a box with one arm, and places it in a strainer. Then with the other arm, it picks up the strainer and boils the noodles for a minute and 40 seconds, rinses off the viscous film on the surface and then dips the noodles in iced water to bring out their firmness. The robot can cook 150 servings in an hour, substituting the work of about one employee.

The CBC Radio show Quirks and Quarks shares an interesting theory: If you find yourself pondering the marvel of aerodynamics when you fly on a plane, or if you concentrate on the structure of music as it plays, rather than simply listening, you may score high on measures of "systemization," according to University of Cambridge neuroscientist Simon Baron-Cohen.

And if so this may reflect abilities that he thinks may have first evolved in humans between 70,000 and 100,000 years ago, when our human ancestors took a cognitive leap forward. This new capacity enabled them to analyze and understand patterns in the world that would, among other things, facilitate the invention of complex tools from bows to musical instruments. In Baron-Cohen's new book, he argues that humans became "the scientific and technological masters of our planet" because of our brain's "systemizing mechanism."

Also, some individuals — particularly those with Autism Spectrum Disorder, are the "hyper-systemizers" of our world. He suggests this should cause us to re-evaluate the capacities and strengths of people with autism... "[F]or the longest time, autism has been really just characterized as a disability, which it is, but with a focus on all the things that autistic people find difficult, what they struggle with. But we know that autism is more than just a disability, that autistic people think differently. Sometimes they have strengths...

"The fact that we can now see a link between those strengths in autism and human invention may change the way we look at autistic people. We might want to see them for who they are, people who think differently and have contributed to human progress."
