Off Barbados, researchers from Bremen have investigated how bacteria inadvertently release methane in order to obtain phosphorus – with significant effects on atmospheric greenhouse gases.
Researchers in ACS Central Science report a proof-of-concept device that “sniffs” seawater, trapping dissolved compounds for analyses. 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.
In a world grappling with a severe water crisis, contamination is a looming threat to public health. Researchers at the U.S. Department of Energy’s Argonne National Laboratory and partners have engineered a breakthrough solution.

Sharks differ from other fish in many ways, including an apparently remarkable ability to heal from wounds, according to reports of sharks recovering from injuries sustained in the wild. 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.

Specialists studied influence of increased salinity on composition of hemolymph – liquid, that circulate in vessels and intracellular hollows of mollusk Anadara kagoshimensis and also examined condition of “blood” cells – hemocytes, that fulfil function similar to blood corpuscle of vertebrates.
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.
