Learning dynamics is essential for model-based control and Reinforcement Learning in engineering systems, such as robotics and power systems. However, limited system measurements, such as those from low-resolution sensors, demand sample-efficient learning. Symmetry provides a powerful inductive bias by characterizing equivariant relations in system states to improve sample efficiency. While recent methods attempt to discover symmetries from data, they typically assume a single global symmetry group and treat symmetry discovery and dynamic learning as separate tasks, leading to limited expressiveness and error accumulation. In this paper, we propose the Latent Mixture of Symmetries (Latent MoS), an expressive model that captures a mixture of symmetry-governed latent factors from complex dynamical measurements. Latent MoS focuses on dynamic learning while locally and provably preserving the underlying symmetric transformations. To further capture long-term equivariance, we introduce a hierarchical architecture that stacks MoS blocks. Numerical experiments in diverse physical systems demonstrate that Latent MoS outperforms state-of-the-art baselines in interpolation and extrapolation tasks while offering interpretable latent representations suitable for future geometric and safety-critical analyses.

The sleek Mayflower Autonomous Ship met with an escort boat as it approached the Massachusetts shoreline Thursday, more than 400 years after its namesake's historic journey from England. It was towed into Plymouth Harbor -- per U.S. Coast Guard rules for crewless vessels -- and docked near a replica of the original Mayflower that brought the Pilgrims to America.

On Thursday, history repeated itself on the shores of Plymouth. In 1620, English pilgrims arrived in North America on the Mayflower. Now, 402 years later, another ship with that name found its way to the Massachusetts coastline. The first Mayflower had more than 100 people on board, the modern version had zero. The Mayflower Autonomous Ship, designed by nautical research company Promare and IBM, completed its voyage from England almost entirely without human assistance.

A crewless robotic boat retracing the 1620 sea voyage of the Mayflower has landed near Plymouth Rock. The sleek Mayflower Autonomous Ship met with an escort boat as it approached the Massachusetts shoreline Thursday, more than 400 years after its namesake's historic journey from England. It was towed into Plymouth Harbor -- per U.S. Coast Guard rules for crewless vessels -- and docked near a replica of the original Mayflower that brought the Pilgrims to America. Piloted by artificial intelligence technology, the 50-foot (15-meter) trimaran didn't have a captain, navigator or any humans on board. The solar-powered ship's first attempt to cross the Atlantic in 2021 was beset with technical problems, forcing it back to its home port of Plymouth, England -- the same place the Pilgrim settlers sailed from in 1620.

A robotic recreation of the 17th century Mayflower ship has finally completed a 3,500 journey across the Atlantic Ocean, in 40 days. Mayflower Autonomous Ship (MAS) – a 50-foot-long autonomous research vessel piloted by artificial intelligence (AI) – arrived in Halifax, Canada on Sunday (June 5). MAS, which carried no humans on board and relied on artificial intelligence, had set sail from Turnchapel Wharf, Plymouth, England in the early hours of April 27. The ship was smooth sailing until the second week of May when a generator issue diverted it to Portugal's Azores islands so a team member could fly in to do repairs. During the latter stages of the journey the decision was made to head to Halifax – as opposed to Virginia as previously planned – due to more mechanical issues.

A groundbreaking AI-powered ship designed by IBM has successfully crossed the Atlantic, albeit not quite as planned. The Mayflower – named after the ship which carried Pilgrims from Plymouth, UK to Massachusetts, US in 1620 – is a 50-foot crewless vessel that relies on AI and edge computing to navigate the often harsh and unpredictable oceans. IBM's Mayflower has been attempting to autonomously complete the voyage that its predecessor did over 400 years ago but has been beset by various problems. The initial launch was planned for June 2021 but a number of technical glitches forced the vessel to return to Plymouth. Back in April 2022, the Mayflower set off again.

The Associated Press reports on "a crewless robotic boat that had tried to retrace the 1620 sea voyage of the Mayflower" from the U.K. to Massachusetts' Plymouth Rock. And after five weeks it finally did reach North America. "The technology that makes up the autonomous system worked perfectly, flawlessly," an IBM computing executive involved in the project told the Associated Press. But "Mechanically, we did run into problems." It's especially disappointing because they'd tried the same voyage last year.

Episode two of Blue Planet II could be one of Sir David Attenborough's scariest shows yet - giving us a glimpse of life in total darkness that we are only just starting to explore. The episode also looks at peculiar gardens that are thriving in the pitch black as well as species of coral that have never been seen in shallower waters. The fangtooth (pictured) has the largest teeth relative to body size for any fish in the entire ocean. The filming of Blue Planet involved around 1,000 people from producers to deep sea divers, researchers to scientists, camera crews to helicopter pilots and drone operators. Some 125 expeditions were undertaken across every ocean, with 1,500 days spent at sea and 6,000 hours underwater.
