Sonar-MASt3R is a new underwater mapping technique developed at MIT and the Woods Hole Oceanographic Institution (WHOI) that may allow vehicles to see through murky, low-visibility waters.

How do you preserve one of the world’s rarest animals when so few remain? Researchers created an unprecedented 3D digital archive of the vaquita — the world’s most endangered marine mammal. Using advanced CT and micro-CT imaging, the team captured the skeleton of a female porpoise from 1966, in extraordinary detail, from its overall anatomy to microscopic bone structures. Freely available online, the models provide a lasting resource for research, education and conservation, ensuring this critically endangered species on the verge of extinction can be studied for generations to come.

PS‑NPs/TPhP alter gut microbiota, impair gut structure and disturb oxidative, inflammatory, detoxifying metabolism via distinct pathways; their antagonistic co‑exposure disrupts lipid metabolism, clarifying gut‑liver-axis risks for salamanders.

Okayama University of Science and Murakami City, Niigata Prefecture, have launched a joint research project to establish the world’s first fully closed-cycle land-based aquaculture system for chum salmon (Oncorhynchus keta) using the university’s proprietary “Third Water” technology. The project aims to address the dramatic decline in salmon returns caused by climate change and changing marine ecosystems. More than 2,000 juvenile salmon are currently being reared in a 35-ton closed recirculation aquaculture system at the university’s Next-Generation Aquaculture Center. Researchers expect the fish to reach market size within one to two years. If successful, the project could provide a sustainable alternative to ocean-dependent salmon production and contribute to the long-term resilience of salmon fisheries in Japan and worldwide.

Researchers from Shanghai Jiao Tong University have successfully utilized a novel screw extrusion-plasticizing friction stir deposition (SEFSD) process to 3D print 5183 aluminum alloy components in the solid state. This innovative approach bypasses the melting phase, significantly reducing common defects like pores and element evaporation. The resulting components showcase a refined microstructure and excellent mechanical properties, paving the way for efficient manufacturing of aerospace and marine structures.

The first published live observations of the rare goblin shark (Mitsukurina owstoni) in its natural deep ocean habitat were reported in a new paper by a University of Hawai‘i at Mānoa-led team of oceanographers. In the past, goblin sharks were only filmed and reported alive after being hooked on a fishing line and hauled to the surface, where divers could observe them and where they soon died. The new study, published in Journal of Fish Biology, documents two live observations of one of the most elusive but iconic sharks on the planet—one at a seamount near Jarvis Island and another on the slope of the Tonga Trench. 

Archaeological evidence from the Canary Islands suggests that by the 11th century, people here were harvesting and processing a variety of fish and other marine organisms — indicating that coastal resources may have played a vital role in the economic system, according to a study published June 10, 2026 in the open access journal PLOS One by Jonathan Santana from the University of Las Palmas de Gran Canaria, Spain, and colleagues.
