Japan-developed AI can aid in fertility treatment
A group led by a University of Tokyo professor created the model by having artificial intelligence study data on over 440 patients. The system takes into account five factors, such as the number of births, as well as age and blood-test results.
The model can then estimate the amount of eggs a patient has. The researchers say its predictions are more accurate than using blood tests alone.
Professor Harada Miyuki at the Graduate School of Medicine, University of Tokyo, said, "Women can use the model to learn more about the condition of their eggs before going through fertility treatment."
The scientists say they have also developed a model that can predict a decline in the quality of a patient's eggs.
The group aims to create an app within a few years that can be used by both medical professionals and individuals.

Panasonic announces new chief as its profits barely hold up
By YURI KAGEYAMA Japanese electronics and technology company Panasonic has chosen a new chief executive at a group company after eking out a 1.2% rise in its first-quarter profit. Kenneth William Sain, a former Boeing executive, will replace Yasuyuki Higuchi as Panasonic Connect's president and chief executive in April 2026, the company said Wednesday. Panasonic Connect offers solutions and products for various supply chains, public services, infrastructure and entertainment sectors. Sain joined Panasonic in 2019 as CEO of Panasonic Avionics. 'Ken is an exceptional leader with extensive global experience and a deep understanding of business and technology,' Higuchi said in a statement. Panasonic Holdings Corp.'s April-June profit totaled 71.46 billion yen ($483 million), up from 70.6 billion yen. Its quarterly sales declined 10.6% from last year to 1.9 trillion yen ($12.8 billion). The Osaka-based maker of home appliances, solar panels and batteries for Tesla vehicles kept its full year profit forecast unchanged at 310 billion yen ($2.1 billion), down 15% from the previous year. Panasonic said the impact from U.S. President Donald Trump's tariffs was not yet fully factored in. The company said it will try to minimize the effect on its operating profit with cost cuts and other measures. Consumer electronics sales were strong in Japan, Panasonic said, while they were also healthy in China, supported by subsidies. On the positive side, it said demand for AI servers and air-conditioners was expected to grow. But concerns remain about slowing demand for electric vehicles because of U.S. tariffs and the ending of tax credits. Panasonic also said it's planning to get its new lithium-ion battery factory in Kansas fully operational later this year, after a delayed start. Panasonic said in May that it was slashing its global workforce by 10,000 people , half in Japan and half overseas, to become 'lean.' The job cuts amount to about 4% of its workforce. © Copyright 2025 The Associated Press. All rights reserved.

China's AI strategy relies on frenzy and frenemies
Wandering through the halls of China's top artificial intelligence this week, I overheard heated debates on some of the thorniest issues facing the sector: How do we solve the problem of interoperability if hundreds of companies are launching their own AI agents? Which large language models are the most developer-friendly to build apps on? Are humanoids tools or companions? Held on the banks of the Huangpu river in Shanghai, the World Artificial Intelligence Conference convened thousands of people — as well as scores of robots — and brought to life all the passions and pitfalls of the current state of AI in China. It also put into stark contrast the chasm between the strategy pushed by Beijing and the one touted by the White House. It's the first major gathering since DeepSeek's breakthrough reasoning model launched earlier this year, driving intense competition at home and proving China can go toe-to-toe with Silicon Valley. With that exuberance came the crowds of challengers, present in so many domestic industries, encouraged by government support and an open-source ecosystem that allows firms to quickly learn from rivals. When one of the so-called Little Dragons, Moonshot, released a massive open-source model that excelled at coding tasks, Alibaba Group was able to update their own Qwen model within about a week to improve benchmarks at the same skills that sent Kimi-K2 viral. Beijing likes to say this approach democratizes access to AI by offering the world the ability to freely build atop its tools, and it gives local developers an edge. China's current AI frenzy represents the best and worst of classic capitalism: The competition propels innovation at a rapid clip, but not all of the companies will survive over the next five or 10 years. During the summit, state-backed media touted how the country has now released 1,500 large AI models — the biggest share globally — and is home to more than 5,000 AI companies. Yet the domestic rivalries on display were overshadowed by a broader, geopolitical contest for supremacy. China's big gathering kicked off just days after U.S. President Donald Trump pledged that that America will "do whatever it takes to lead the world in artificial intelligence.' After unveiling a so-called AI Action Plan, he went on to declare that America is the country that started the AI race and "is going to win it.' In Shanghai, Premier Li Qiang headlined opening night by announcing that China will organize the launch of an international body to jointly develop the technology, with the goal of preventing it from becoming "an exclusive game for a small number of countries and enterprises.' It dovetailed with this year's conference theme: "Global solidarity in the AI era.' China is willing to share its development and products with the world, Li said, especially in the Global South. Still, what these world leaders say is one thing, what they do is another. Trump's declaration of doing whatever it takes to win follows his decision to hand a major gift to Chinese AI firms. Washington reversed course on semiconductor restrictions, allowing Nvidia's highly sought-after H20 chips to resume sales on the mainland. The policy U-turn was announced in the midst of, and likely influenced by, ongoing trade talks. It also came after Nvidia Chief Executive Officer Jensen Huang lobbied for his company to be able to keep its multibillion-dollar slice of the lucrative China market. And as much as Li pitches "solidarity,' it's unclear how many countries will ultimately choose to align with China. Yet it's a far cry from Washington's "America First' AI policy goals and signals that Beijing's that approach relies on convincing the world to use its plethora of low-cost AI products being rapidly released. Fresh access to Nvidia processers is giving the industry new momentum and the increasingly crowded field is driving down prices. Compare the two and China's plan seems more strategic in the long run. One of the forums on Sunday featured a Zoom appearance from pioneering AI godfather Yoshua Bengio, who warned that the U.S.-China competition was dangerous and that development was progressing so rapidly it may become impossible for humans to control. Bengio has a point. But is anybody listening? Ambitions of AI acceleration from both sides of the Pacific suggest not. Catherine Thorbecke is a Bloomberg Opinion columnist covering Asia tech.

Qudan Rie: The 'Sympathy Tower Tokyo' Author on Language and Rhythm
After Qudan Rie's Sympathy Tower Tokyo won the prestigious Akutagawa Prize last year, the author created a stir by admitting at a press conference that she had used AI to write 'about five percent of the whole.' The novel is set in an alternative version of Japan, where the 2020 Tokyo Olympics were held on schedule in the New National Stadium designed by Zaha Hadid—a plan scrapped in reality for budgetary reasons. The novel's narrator and main character, Makina Sara, is an architect working on designs for a new prison to be called Sympathy Tower Tokyo, in a society marked by what she regards as excessive tolerance toward criminals. Even as she dedicates herself to the project, Makina struggles with reservations about the name of the tower and the concept itself. The novel centers on the project to build the tower, which Makina describes as the 'return of the Tower of Babel,' and depicts a world littered with inorganic language pumped out by generative AI, degraded by katakana coinages and impersonal terms bereft of tangible meaning. It asks probing questions about contemporary Japanese language and society. The book quickly drew attention in other countries after the award was announced. Translations have already been published in South Korea, Taiwan, France, Italy, and Germany. An English translation by Jesse Kirkwood will appear in Britain in August and in the United States in September, and the book is slated to appear in at least six other markets, including Russia. AI as Collaborator The statement that she had used AI for part of her novel took on a life of its own and caused more of a stir than she had ever imagined. Qudan says she did not initially plan to make strategic use of AI. 'The only thing I knew was that it was going to be a story about architecture and language. I never think too much about the plot in advance. I start writing, and then connect the story to my own life as I go. That's the way I always write. 'I started working on Sympathy Tower Tokyo around two years ago, just as ChatGPT was making the headlines. I tried it out myself, out of curiosity really. At the time, I was feeling uncertain about my future as a writer, and began by asking ChatGPT for advice. That's how it started. (© Hanai Tomoko) 'I asked: What can I do to get back up when I am feeling down? I just threw out this simple question, but the response was much more than I expected. The text that came back was comparable to an advice column by a psychiatrist. I thought it was fascinating. 'But as I interacted more with ChatGPT, I became aware of the ways in which the dialogue differed from a real conversation between two human beings, and I came to understand the limits of what AI could do. I thought if I could find a way to express in a novel the discomfort I was feeling at my interactions with AI, it might lead to an interesting chemical reaction. That's where the idea came from.' In fact, Qudan used her interactions with AI only as material for AI responses to questions posed by the heroine of her novel. The 'five percent' figure was something she came up with on the spot at the press conference. 'In interviews over the year or so after I won the award, people kept asking me about that number. Exactly which parts are the five percent? How did it feel to use AI for five percent of your novel? The questions kept coming. And I never felt confident that I'd answered them well. I didn't think I'd fully explained the sense of distance I felt between myself and the AI.' Then she was approached by an editor at the advertising magazine Kōkoku with a proposal for a 'collaborative project with AI,' in which she would write 5 percent of a story and generative AI would create the remaining 95 percent. It occurred to her that this might provide herself and the public with a clearer answer than her fumbling answers to interview questions, by allowing people to compare the '5 percent' AI of Sympathy Tower with the '95 percent' AI of the new project. 'And so, with that idea in mind, I decided to accept the challenge.' The short story that resulted, 'Shadow Rain,' as well as the lengthy dialogue and prompts that led to its completion, have now been published online. The results show clearly what it means for an AI to 'write a novel' at the current stage of development. Qudan herself has said in a related interview that, 'The AI didn't come up with any ideas far beyond human intelligence.' In the Beginning Was the Word Qudan has published four pieces of fiction since her debut with Bad Music in 2021. Each has been markedly different. 'When I sit down to write, I think about what kind of language the story needs, what style is best suited to the story I want to tell. I can't settle into the work until I have answered those questions to my own satisfaction. So certain words and phrases exist in my mind before I even start to write.' (© Hanai Tomoko) Where does this attitude toward language come from? 'I've been on this planet for 34 years now, and ever since I was a child, I've always felt there's something mysterious about life. That's part of what led to my becoming a writer, I think. I tend to use language as a way of proving I'm alive. I transform my life into language and immerse myself in thought.' Qudan says the ideas for her stories come to her in different ways. The concept for her second work, ' Schoolgirl ,' was to write an updated 2022 version of the story ' Schoolgirl ' by Dazai Osamu published in 1939. Qudan's version depicts a 14-year-old girl who broadcasts her thoughts to the world via an online video site about environmental issues and her relationship with her mother. In her third piece, the novel Horses that Write Poems , horse racing is a major element in the story, which depicts the history of the relationship between humanity and horses. It is studded with the names of famous horses and racing commentary. 'With that story, the words 'horses that write poems' came into my head one day when I woke up from a nap. I just felt intuitively that I wanted to use those words as the title to a story. I did quite a lot of research, and horse racing was one of many subjects I looked into to help me write the story.' In the case of Sympathy Tower , it was the phrase 'the return of the Tower of Babel' that came first—Qudan says she felt she absolutely had to use it somewhere in the story. To improve her understanding of her subject, she says, she read stacks of books by architects, and was also influenced by Mishima Yukio's famous novel The Temple of the Golden Pavilion about the burning of the Kyoto temple Kinkakuji. 'Mishima Was My First Love!' Mishima has long played a special role in Qudan's life. When she was 14, she watched video online of a famously fiery debate at the University of Tokyo in 1969, in which Mishima contended with leftwing students from the All-Campus Joint Struggle League ( Zenkyōtō ). 'I really loved Mishima. He was my first love! His voice and the way he looked in the film just gave me a thrill, and then after I read his novels I fell deeply and seriously into his work. I loved everything about him, including his prose style. But since my introduction to Mishima was through his appearance and voice, every time I reread his books, I hear his voice playing in my head.' In her third year of junior high school, Qudan stopped attending. Her parents had divorced, and she had moved schools at a difficult age. Qudan's own analysis, looking back on it now, is that this may have been one of the factors that drew her to Mishima and his work. 'When I encountered him, I was starting to despair about my future. I was worried that because I'd been absent so often, I wouldn't be able to graduate or go on to high school. 'It was a hard time. I had no friends I could turn to, and the burden was too heavy for me at 14. I didn't talk to any other children my age, and my most meaningful communication was with books. For nearly a decade, I communicated day in and day out mostly with dead people—Mishima foremost among them.' This memory of her childhood self, desperately trying to find a way to mend her parents' broken relationship and the breakdown in communication, alongside her feelings of disappointment and failure, have stayed with her. 'That might be part of what made me so interested in language and communication,' she says. (© Hanai Tomoko) Rhythm More Important than Literal Meaning in Translation Over the past few years, Qudan has become an enthusiastic gym-goer, inspired by the example of Mishima, who began serious bodybuilding when he was 30. She believes there is a close relationship between the body and literary style, and is convinced that her prose has changed as her body has become leaner and more honed. She is also a music lover, listening to everything from classical to hip-hop. Just as with music, she says, 'in writing too, rhythm is vital.' Given that Qudan is so particular about language and style, how does she feel about translation, now that her novel is appearing in so many different languages around the world? 'When I met Jesse Kirkwood [who translated Sympathy Tower Tokyo into English] last year, I told him I wanted him to prioritize the rhythm of the English, even if some of the meaning from the original text might be lost. 'I don't have big hang-ups about accuracy. Readability in English is much more important. Jesse had already translated a short story of mine.' (' Planet Her, or the Oldest Female Rapper in the World.') In that story, it would have been impossible to translate all the Japanese rhymes, so in that sense it's not faithful to the original. But I felt he was sensitive to the rhythm. When I understood that he was thinking seriously about the rhythmical demands of English, I knew I could trust him absolutely as a translator.' Tōkyō to dōjōtō (left) and Sympathy Tower Tokyo , the English translation due to be published in August. (Courtesty Shinchōsha) Writing by Japanese women has been attracting attention overseas in recent years. At first, even Qudan suspected that the widespread interest in translating her novel was thanks to a perfect trifecta of on-trend hot topics: 'AI,' 'Akutagawa Prize,' and 'Japanese woman writer.' But after attending events at book fairs in Taiwan and Italy this year, she says she has been struck by how genuinely enthusiastic her overseas publishers are about her work. 'My Italian publisher, L'Ippocampo, normally specializes in visual and children's books. They rarely publish novels, and this was obviously the first time they'd published one from Japan. I learned that the decision to translate and publish my novel came from the personal enthusiasm of an editor passionate about Japanese culture and literature. That really made me appreciate how vital such passion is to the process of translating and publishing a work in another country.' What kind of rhythms will Sympathy Tower Tokyo beat out in languages worldwide? And what surprising topics will Qudan turn to next to delight her readers? We look forward to her next imaginative journey.
