Japan's oyster industry is facing a severe crisis as a mass die-off of oysters in the country's Hiroshima prefecture threatens the livelihoods of local fishermen and the national cuisine. The die-off, which has resulted in up to 90% of oysters dying in some areas, is attributed to a combination of rising sea temperatures and a brutally hot summer last year.The oyster industry in Hiroshima accounts for almost two-thirds of Japan's supply of farmed oysters, producing 89,000 tons of the shellfish in 2023. The industry's struggles have prompted the government to step in with support measures, including five-year government loans at virtually zero interest and access to mutual aid programs for aquaculture businesses.Experts warn that mass die-offs could become more common due to climate change and global warming. 'It's difficult to put the brakes on climate change,' says Kazuhiko Koike, a professor at Hiroshima University. 'But if the rainy season ends early again with little rainfall, and is followed by prolonged high temperatures and hot weather, this could mean that low oxygen levels and food shortages will occur again.'The crisis has significant implications for local businesses and consumers, with oyster's being a popular Japanese dish. 'This is something out of the ordinary,' says Taketoshi Niina, a fishery owner in Kure. 'A lot of those that do survive are in poor condition … they are not of a high enough quality to sell to shops and restaurants.'

Submersible hydroelectric systems are emerging as a pivotal component of North America’s clean‑energy strategy, especially as the Trump administration eliminates key subsidies for solar and wind. The technology, already proven in Alaska and Maine, is now being deployed in the densely populated Great Lakes corridor, where electricity demand and prices are climbing sharply. Last month, Ocean Renewable Power Company (ORPC) announced its first urban installation on the St Lawrence River in Montreal, slated to launch two carbon‑fiber turbine units later this year. ORPC’s CEO Stuart Davies highlighted the river’s “consistent, high‑velocity water” and estimated a 60‑90 MW resource potential for the Montreal area alone. In parallel, ORPC is preparing a second project on the Niagara River near Buffalo, New York, and plans a future deployment on the lower Mississippi River between Baton Rouge and New Orleans. The timing coincides with record electricity price spikes across the Great Lakes. New York’s public service commission approved substantial rate hikes in September, and further increases are scheduled for 2027, while Michigan and Ohio face similar pressures driven by data‑center expansion. These economic pressures are driving interest in marine‑based power. Unlike traditional hydropower, ORPC’s devices resemble “push‑lawn‑mower blades” and can generate between 0.5 MW and 5 MW continuously, offering a potential baseload for industrial users and a reliable backup during grid outages. Environmental considerations remain central. While Quebec benefits from long‑standing, low‑cost hydropower, U.S. projects endure an average eight‑year licensing timeline. Critics worry about impacts on fish and wildlife, though ORPC cites its Alaska deployment—operating since 2019 without recorded fish injuries despite massive salmon migrations—as evidence of minimal ecological risk. Researchers are also expanding the technology’s reach to slower‑moving waters. University of Michigan professor Michael Bernitsas demonstrated the Vivace system on the St Clair River, capable of harvesting energy from currents as low as 0.5 m/s, suggesting broader applicability across the Great Lakes watershed. Operating in fresh water offers a distinct advantage: the absence of salt eliminates corrosion, extending turbine lifespan and reducing costs compared with ocean‑based projects. Some European tidal installations have even anchored devices to riverbeds to avoid ice damage, a practice ORPC may adopt. Financially, the sector benefits from a 40‑50 % investment tax credit that remains intact, even as the Trump administration phases out Biden‑era subsidies for solar and wind. The National Hydropower Association confirms that marine‑energy tax incentives will stay in place through at least 2033, reshaping the competitive landscape and attracting inquiries from entities in over 70 countries. As electricity bills rise and policy shifts favor alternative renewables, submersible hydropower could become a cornerstone of the Great Lakes’ energy mix, delivering resilient, low‑carbon power while navigating regulatory and environmental hurdles.

Leicester City Women are staring down the barrel of relegation to the second tier after a disheartening 1-0 loss to Brighton in the Women's Super League. The defeat, which came on a soggy afternoon at the King Power Stadium, has left them four points adrift at the bottom of the table with only four games remaining.The sight of two young girls proudly waving 'Foxes never quit' flags in the rain-soaked stands encapsulated the never-say-die attitude required for a relegation battle that Leicester now finds itself in. Despite the bleak outlook, manager Rick Passmoor and the fans remain optimistic about their chances of survival.The latest setback came against Brighton, who showed their class on the ball, particularly in the first hour. Fran Kirby's movement and creativity caused significant problems for the Leicester defense. The decisive moment arrived when Kiko Seike broke the deadlock by tucking home Rosa Kafaji's unselfish pass, following a sublime through ball from Kirby.Leicester's struggles this season can be attributed largely to operating on what is believed to be the lowest budget in the top tier, compounded by the loss of key players such as Ruby Mace and the Japan duo Saori Takarada and Yuka Momiki last summer. The team is on a seven-match losing run in the league, which has coincided with Liverpool's significant upturn in results following their January transfer activity.There is still a potential lifeline for Leicester in the form of a one-leg playoff fixture against the third-placed team in the second tier, scheduled for May 23. However, their opponents have yet to be determined, with Crystal Palace and Birmingham keeping the automatic promotion race on a knife-edge.The women's predicament comes at an uncertain time for the football club as a whole, with the men's team in the Championship relegation zone, a point from safety after being deducted six points for overspending. It could yet be a campaign to forget for both the men's and women's sides.

A humpback whale, approximately 10 metres long, has become stranded for the third time on Germany's Baltic coast. The mammal, believed to be male, appeared weakened and sick on Sunday, struggling to find a route back to the Atlantic.**The prognosis for the whale's survival is grim**, according to Burkard Baschek, a marine scientist. The whale's breathing frequency has reduced, and it no longer exhibits reactions to nearby vessels.Till Backhaus, the environment minister of Mecklenburg-Western Pomerania, established a 500-metre restricted area around the animal to give it a chance to rest and hopefully free itself. However, **the chances of success are relatively slim**, according to Baschek.The whale was first spotted in the Baltic on 3 March and reported stranded on a sandbank last week. Authorities used an excavator to deepen a channel and boats to create waves to help free the mammal, which was nicknamed Timmy. Despite being freed once, it became trapped again on Sunday.**The whale's respiratory rate has dropped considerably**, and it is not moving, according to Stephanie Gross of the Institute for Terrestrial and Aquatic Wildlife Research. Even if the whale frees itself again, it would need to navigate narrow straits and approximately 310 miles to reach relative safety.Humpback whales are not native to the Baltic, and experts suspect that the young whale followed a shoal of fish or became disoriented by the noise of a submarine. **The lack of salt concentration and nutrition in Baltic waters makes it difficult for humpbacks to survive in the long term**.

An active oil spill in the Gulf of Mexico has spread across seven nature reserves, covering an area of more than 600km (373 miles). The spill, which originated from an unidentified vessel and two natural sources, has had devastating effects on local wildlife and ecosystems.Mexican authorities have confirmed that the spill has killed sea turtles, a manatee, and various fish species. Additionally, reports from communities in the area indicate that approximately 17 reefs have been damaged. Oceana, an international organization focused on ocean conservation, highlighted these findings, emphasizing the severity of the environmental impact.The sources of the spill have been identified as a vessel docked off the coast of Coatzacoalcos in Veracruz, a geological site known as a 'chapopotera' 8km from the Coatzacoalcos port, and another natural leak site in the Bay of Campeche. The Navy Secretary, Admiral Raymundo Morales, confirmed that the spill point remains active, with a greater flow of contaminants observed in the last month.Environmental organizations, including Greenpeace Mexico, have denounced the alleged inaction by state authorities, calling for faster communication and mitigation of the damage. The Gulf of Mexico has been treated as a 'sacrifice zone for the oil industry,' according to Greenpeace, which urged the government to design and implement effective protocols to prevent and respond to environmental risks associated with oil activities.At least six species, including sea turtles, birds, and fish, have been contaminated so far. The incident has also raised concerns about the potential impact on oysters in the connected Mecoacan lagoon and the fishermen harvesting them, particularly after an explosion occurred at the Olmeca refinery on March 17, resulting in five fatalities.

The reintroduction of beavers in Dorset has shown promising results, with the animals building a 35-metre dam and creating a deep, wildlife-rich pool. By coppicing trees, they have allowed more light in and improved habitats for plants, insects, amphibians, birds, and bats.Trail cameras have captured footage of an otter fishing in the pond, as well as a barn owl hunting there. Volunteers have spotted birds including redpolls and water rails. The cameras also captured footage of two of the beavers mating, indicating they have settled in their new home and that there could be kits this summer.Despite some hitches, including the death of a male beaver and the relocation of a female, the western pair of beavers has been busy doing their engineering work. The National Trust, which is in charge of the project, said it was thrilled with the progress, highlighting the astonishing effect on the ecosystem in a relatively short time.Gen Crisford, the National Trust's wetlands project officer, said setbacks were inevitable but expressed hope for a 'happy ever after moment' with the western pair. The project allows for the release of 10 to 25 adult beavers, with the next release expected to take place this autumn.

Tracy Kidder, an award-winning narrative nonfiction writer, has passed away at the age of 80. Kidder was known for his ability to transform unlikely subjects into bestsellers, captivating readers with his in-depth research and storytelling skills. Throughout his career, Kidder immersed himself in various worlds, producing richly researched books on topics that may not have seemed like light reading. His work included The Soul of a New Machine, which explored the inner workings of a fledgling computer company in Silicon Valley and earned him the Pulitzer Prize and National Book Award in 1981. Kidder's other notable works include Among Schoolchildren, which highlighted the dedication of an inner-city teacher in Holyoke, Massachusetts, and Old Friends, which chronicled the lives of two friends in a nursing home. His book Mountains Beyond Mountains, about a doctor's efforts to bring healthcare to Haiti, introduced his work to a new generation of readers and inspired numerous universities to add it to their reading lists. Kidder's approach to storytelling was rooted in his belief that small things can have a significant impact. He avoided focusing on his personal interests, such as fishing or baseball, to maintain his objectivity and enthusiasm for his subjects. Kidder saw himself as a storyteller, not a 'literary journalist' or 'creative nonfiction' writer, and believed that nonfiction should not be limited by traditional techniques. Born in New York City in 1945, Kidder attended Harvard University and served in Vietnam, where he documented his experiences in My Detachment, a memoir that offered insights into the lives of support troops.

The relationship between dogs and humans has long been a subject of fascination, and recent groundbreaking research has shed new light on the origins of this enduring bond. Published in the journal Nature, the study reveals that the genetic evidence for domestic dogs dates back an astonishing 15,000 years, a full 5,000 years earlier than previously thought.Ancient DNA analysis of dog remains has provided unprecedented insight into the early days of dog domestication. The oldest specimen, a 15,800-year-old dog buried alongside human remains in Anatolia, Turkey, and a 14,300-year-old jawbone from Gough's Cave in Somerset, England, are key findings that have helped researchers reevaluate the timeline of dog domestication.According to Dr. Lachie Scarsbrook of Ludwig Maximilian University of Munich, the study suggests that dogs with diverse ancestries already existed across Eurasia 15,000 years ago, from Somerset to Siberia. This raises the possibility that domestication occurred during the last ice age, more than 10,000 years before the emergence of other domestic plants and animals.The research, conducted by international teams, analyzed DNA from bones at various sites, including Gough's Cave, Pınarbaşı in Turkey, and two sites in Serbia. Advanced sequencing techniques allowed researchers to piece together tiny fragments of ancient DNA, enabling clear species identification for the first time.Key findings include:Dogs were widespread across Europe and western Asia by at least 14,000 years ago.Isotopic analysis revealed dogs consumed a diet rich in fish, matching the local human diet in Turkey.Evidence of deep emotional bonds between humans and dogs, including the burial of puppies over human remains.The study's authors suggest that dogs may have increased hunting efficiency or served as an early warning system against predators. The genetic relationship between dogs across sites implies that they may have spread rapidly across Europe, possibly through trade between unrelated groups.As Prof. Laurent Frantz notes, the fact that people exchanged dogs so early suggests these animals must have been important, serving purposes beyond being pets. The research provides a fascinating glimpse into the ancient partnership between humans and dogs, highlighting the significance of this bond in human history.

Six decades ago, pioneering oceanographer and conservationist Sylvia Earle made a remarkable discovery while diving off Chile’s oceanic islands. She found the remains of a baby fur seal, a species endemic to the Juan Fernández archipelago that was believed to have been hunted to extinction in the 19th century. This discovery gave Earle hope that a small population might still exist, and indeed, a year later, a colony of 20 endemic fur seals was confirmed on Robinson Crusoe Island.Today, after decades of conservation efforts, the fur seal population has made an extraordinary recovery. An estimated 200,000 fur seals now inhabit the waters around the islands, returning them to their previous role as key members of the ecosystem. Earle, now 90, who returned to the island to dive in December 2025, described the archipelago as a critical 'Hope Spot' for marine protection.In a significant conservation victory, outgoing Chilean President Gabriel Boric recently signed an agreement to extend protection of 337,000 sq km of waters around Juan Fernández and the nearby Nazca-Desventuradas marine park. Once implemented, this 'no take' zone will extend to almost 1 million sq km, making it the third-largest such marine protected zone in the world. By doing so, Chile would protect more than 50% of its waters, placing it in a rare category alongside countries such as Panama and French Polynesia.The protection prohibits all fishing activities except within 12km of the coast, allowing the community of approximately 1,000 lobster fishers to continue their traditional livelihood. Chile is now out in front globally in ocean protection efforts, according to Earle, as most countries have been slower to commit to such extensive marine conservation.The initiative was driven by the Juan Fernández islanders and conservation NGOs who have advocated for decades to protect the unique ecosystem. The fishers, who witnessed the damage caused by industrial fishing of the orange roughy in the 1990s and 2000s, have practiced stewardship of their fishery. A survey showed 98% of residents supported extended protections, leading the fishers to present a proposal directly to the president.Julio Chamorro Solís, a lobster fisher and president of the local fishing organization, emphasized the importance of the unique ecosystem: 'We know the level of endemism we have and how fragile this ecosystem is. There's a biological treasure here.'However, the future of this expanded protection remains uncertain. The new Chilean government, led by President-elect José Antonio Kast, is currently reviewing environmental laws established by the previous administration. While the Chilean ministry of the environment has stated its intention is not to eliminate protections, conservationists and islanders await confirmation that the marine park extension will proceed as planned.This initiative aligns with global commitments to protect 30% of the world's oceans by 2030, a goal reinforced by the recent implementation of the high seas treaty. The expansion of Chile's marine protected areas represents a significant step toward achieving this ambitious target while safeguarding one of the planet's unique marine ecosystems.
