Nearly 12,000 viruses previously unknown to science have been discovered in the Pacific Ocean

In the Clarion-Clipperton Zone in the Pacific Ocean, scientists have discovered 11,742 viruses, about 99% of which had not been previously described. The researchers believe these viruses may play an important role in the functioning of the deep-sea ecosystem.

Scientists collected samples of seafloor sediments in 2023 and 2024, after which they analyzed the viruses’ genetic material. The results of the study were published in the journal *Nature Communications*.

 The Clarion-Clipperton Zone is known for its large deposits of polymetallic nodules containing manganese, cobalt, nickel, lithium, and zinc. These resources have industrial value, which is why the region is being considered for future deep-sea mining.

At the same time, the nodules are an important part of the local ecosystem. Various organisms live on them, and many of the viruses identified likely infect bacteria and archaea involved in the cycles of carbon, nitrogen, phosphorus, sulfur, and metals.

Scientists suggest that the viruses found may influence chemical processes in seafloor sediments. However, their exact role in the ecosystem remains poorly understood.

The researchers emphasize that potential mineral extraction could physically disturb the seafloor, stir up sediments, and alter the habitat of microorganisms. Therefore, the data obtained could serve as a baseline for assessing the future impact of such operations.

Since the beginning of the year, Italy has recorded more than 650 cases of West Nile virus infection—roughly half of all cases reported in Europe. Italian health authorities attribute the spread of the infection to new areas and the extended transmission season to rising temperatures and longer warm spells.

In China, state media and local authorities have called on content creators, fan communities, and online platforms to curb the pursuit of online attention, which infringes on people’s privacy and disrupts the operation of government services.
