14 award-winning images of our mighty oceans
The 2025 Ocean Photographer of the Year announced its winners this week. This photo was taken on April 1, 2024, off Point No Point, WA. In Puget Sound, there's a community of people who prefer watching orcas from the land rather than from boats. Land-based whale watchers in Puget Sound can sometimes get lucky, as these wild apex predators occasionally approach the shore, seemingly curious about their human spectators. My friend is one of those land-based whale enthusiasts, and April 1, 2024, was no ordinary day for her.
New species of coral named after Chewbacca
Breakthroughs, discoveries, and DIY tips sent every weekday. While it's not helping fly the Millennium Falcon, marine biologists have discovered a new type of deep-sea coral in the western Pacific Ocean that bears a striking similarity to a certain beloved character. A new scientific analysis of the species initially documented almost two decades ago indicates that is its own species, with long, hairlike branches that live up to its namesake Wookie. Ten years later, another example was documented close to the Mariana Trench . But it would take a few more years before University of Hawai'i ecologist Les Watling noticed the strange, ethereal sight while reviewing research from some of his colleagues.
Japan political party to install AI leader
An upstart Japanese political party said Tuesday it will install an artificial intelligence as leader after its maverick founder quit following a disastrous showing in recent elections. The Path to Rebirth party, which was launched in January by Shinji Ishimaru, a former mayor of a small city in western Japan, does not have a policy platform and its members are free to set their own agendas. Ishimaru unexpectedly came second in the 2024 Tokyo gubernatorial election thanks to a successful online campaign but he quit the party after it failed to pick up any seats in this year's upper house elections. The new leader will be AI, Koki Okumura, a doctoral student of AI research who described himself as an assistant to the new leader, told a news conference. Shinji Ishimaru, leader of The Path to Rebirth party, holds a news conference in August in Tokyo.
'I have to do it': Why one of the world's most brilliant AI scientists left the US for China
'I have to do it': Why one of the world's most brilliant AI scientists left the US for China In 2020, after spending half his life in the US, Song-Chun Zhu took a one-way ticket to China. By the time Song-Chun Zhu was six years old, he had encountered death more times than he could count. This was the early 1970s, the waning years of the Cultural Revolution, and his father ran a village supply store in rural China . There was little to do beyond till the fields and study Mao Zedong at home, and so the shop became a refuge where people could rest, recharge and share tales. Zhu grew up in that shop, absorbing a lifetime's worth of tragedies: a family friend lost in a car crash, a relative from an untreated illness, stories of suicide or starvation. "That was really tough," Zhu recalled recently. The young Zhu became obsessed with what people left behind after they died. One day, he came across a book that contained his family genealogy. When he asked the bookkeeper why it included his ancestors' dates of birth and death but nothing about their lives, the man told him matter of factly that they were peasants, so there was nothing worth recording. He resolved that his fate would be different. Today, at 56, Zhu is one of the world's leading authorities in artificial intelligence. In 1992, he left China for the US to pursue a PhD in computer science at Harvard. Later, at University of California, Los Angeles (UCLA), he led one of the most prolific AI research centres in the world, won numerous major awards, and attracted prestigious research grants from the Pentagon and the National Science Foundation. He was celebrated for his pioneering research into how machines can spot patterns in data, which helped lay the groundwork for modern AI systems such as ChatGPT and DeepSeek. He and his wife, and their two US-born daughters, lived in a hilltop home on Los Angeles's Mulholland Drive. He thought he would never leave. But in August 2020, after 28 years in the US, Zhu astonished his colleagues and friends by suddenly moving back to China, where he took up professorships at two top Beijing universities and a directorship in a state-sponsored AI institute.
Billion-dollar coffins? New technology could make oceans transparent and Aukus submarines vulnerable
Australia's forthcoming Aukus nuclear-powered submarines have been called the'apex predator of the oceans'. Australia's forthcoming Aukus nuclear-powered submarines have been called the'apex predator of the oceans'. Quantum sensing, satellite tracking and AI are part of an accelerating arms race in detection that should prompt a re-evaluation of Australia's defence strategy Military history is littered with the corpses of apex predators. All once possessed unassailable power - then were undermined, in some cases wiped out, by the march of new technology. " Speed and stealth and firepower," the head of the Australian Submarine Agency, Jonathan Mead, told the Guardian two years ago of Australia's forthcoming fleet of nuclear submarines.

Australia to spend 1.1bn on underwater 'Ghost Shark' attack drones
Australia to spend $1.1bn on underwater'Ghost Shark' attack drones Australia will spend 1.7 billion Australian dollars ($1.1bn) on a fleet of extra-large underwater "Ghost Shark" attack drones, in a move that officials said would supplement the country's plans to acquire sophisticated nuclear-powered submarines. Australian Minister for Defence Richard Marles said on Wednesday that the Ghost Shark autonomous underwater vehicles will complement Australia's naval surface fleet and submarines to provide "a more capable and more lethal navy". "We have consistently articulated that Australia faces the most complex, in some ways, the most threatening, strategic landscape that we have had since the end of the second world war," Marles said. The government said it signed the $1.1bn, five-year contract with Anduril Australia to build, maintain and develop the uncrewed undersea vehicles in Australia. "This is the highest tech capability in the world," Marles said, adding that the drones would have a "very long range" as well as stealth capabilities.
Evaluating Retrieval-Augmented Generation Strategies for Large Language Models in Travel Mode Choice Prediction
Accurately predicting travel mode choice is essential for effective transportation planning, yet traditional statistical and machine learning models are constrained by rigid assumptions, limited contextual reasoning, and reduced generalizability. This study explores the potential of Large Language Models (LLMs) as a more flexible and context-aware approach to travel mode choice prediction, enhanced by Retrieval-Augmented Generation (RAG) to ground predictions in empirical data. We develop a modular framework for integrating RAG into LLM-based travel mode choice prediction and evaluate four retrieval strategies: basic RAG, RAG with balanced retrieval, RAG with a cross-encoder for re-ranking, and RAG with balanced retrieval and cross-encoder for re-ranking. These strategies are tested across three LLM architectures (OpenAI GPT-4o, o4-mini, and o3) to examine the interaction between model reasoning capabilities and retrieval methods. Using the 2023 Puget Sound Regional Household Travel Survey data, we conduct a series of experiments to evaluate model performance. The results demonstrate that RAG substantially enhances predictive accuracy across a range of models. Notably, the GPT-4o model combined with balanced retrieval and cross-encoder re-ranking achieves the highest accuracy of 80.8%, exceeding that of conventional statistical and machine learning baselines. Furthermore, LLM-based models exhibit superior generalization abilities relative to these baselines. Findings highlight the critical interplay between LLM reasoning capabilities and retrieval strategies, demonstrating the importance of aligning retrieval strategies with model capabilities to maximize the potential of LLM-based travel behavior modeling.
