The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
If you’ve ever witnessed a shark breach the water—whether in person or somewhere on the Internet—that fleeting but awe-inspiring moment is just a small fraction of the time it spends at the surface of the ocean. Most of the time sharks and other large marine predators are out of sight, begging the question—where do they go?
A group of the world’s leading ocean scientific, philanthropic, and other stakeholder organizations, led by the Woods Hole Oceanographic Institution (WHOI) and Scripps Institution of Oceanography at the University of California San Diego, have come together to highlight the global ocean at the upcoming 28th Conference of the Parties (COP28) in Dubai, United Arab Emirates, Nov. 30 – Dec. 12, 2023. The conference is expected to host over 70,000 delegates, including heads of state and world leaders, to build consensus and facilitate progress on climate action among 197 countries, the EU and thousands of non-government organizations, companies, youth groups, and other stakeholders focused on efforts to achieve the goals laid out in the Paris Agreement.

While this healing ability has not yet been documented in controlled laboratory conditions, some of the chemical compounds found in shark skin may have significant biomedical potential.

Viruses are the most prevalent biological entities in the world’s oceans and play essential roles in its ecological and biogeochemical balance. Yet, they are the least understood elements of marine life. By unraveling the entire genome of a certain marine protist that may act as a host for many viruses, an international research team led by scientists from Stony Brook University sets the stage for future investigations of marine protist genomes, marine microbial dynamics and the evolutionary interplay between host organisms and their viruses – work that may open doors to a better understanding of the “invisible” world of marine viruses and offers a key to the ecology and health of oceans worldwide. The research is published early online in Current Biology.
Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska’s Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior.

The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur – a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs.
Often introduced unintentionally by human activities, invasive alien species can outcompete and overwhelm native flora and fauna, driving species to the brink of extinction and disrupting the balance of ecosystems
Dr. Jae-Woo Choi of the Center for Water Cycle Research at the Korea Institute of Science and Technology (KIST) has developed an eco-friendly metal-organic skeleton-based solid flocculant that can effectively aggregate nanoplastics under visible light irradiation.
Global coastal adaptations are ‘incremental in scale’, short-sighted and inadequate to address the root causes of vulnerability to climate change, according to an international team of researchers.
Researchers have been able to pinpoint exactly when the muddy off-flavor emerges in farmed fish, which could help to make it easier to deal with the compounds that turn people away from farmed fish

During the Early-Middle Devonian period, a large landmass called Gondwana—which included parts of today's Africa, South America, and Antarctica—was located near the South Pole. Unlike today's icy conditions, the climate was warmer, and the sea levels were higher, flooding most of the land.
Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a University of Otago study showing they are still harmful to fish.
As the wind and rain pound the blades of a wind turbine, UBC Okanagan researchers carefully monitor screens, hundreds of kilometres away analyzing if the blade’s coatings can withstand the onslaught.

About 30 miles off the coast of eastern North Carolina stands Frying Pan Tower, a local maritime relic that looms over a frying pan-shaped, sandy ridge known as Frying Pan Shoals. Treacherous for boaters yet a saltwater angler’s dream, the shoals are known for strong currents and shallow waters that have caused hundreds of shipwrecks through the years, but also harbor a thriving, high-producing ecosystem that includes an elaborate web of marine life from microscopic phytoplankton to shrimp, crab, and baitfish, to sea birds, loggerheads and porpoise, to grouper, billfish and sharks.
