The Antarctic is a harsh and unforgiving climate for many, though there is no shortage of important biological activity ...

Elephant seals lie dead on a beach in Argentina following an outbreak of avian influenza in the region. (Maxi Jonas) The highly pathogenic avian influenza virus H5N1 has adapted to spread between ...

Study reveals new insights into giant viruses and their role in marine ecosystems. Giant viruses play a role in the survival of single-celled marine organisms called protists. These include algae, ...

Scientists have uncovered over 200 new giant viruses lurking in ocean waters that not only help shape marine ecosystems but also manipulate photosynthesis in algae. These massive viruses once nearly ...

On land, photosynthesis is carried out by plants, and the impacts of the process can be seen with the autumn leaves changing color and new green leaves in the spring. But in the ocean, the process is ...

Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean ...

Giant viruses play a role in the survival of single-celled marine organisms called protists. These include algae, amoeba, and flagellates, that form the base of ocean food webs. And since these ...

Within the complex hierarchy of marine ecosystems, giant viruses are now being recognized as novel drivers of both ecological balance and carbon cycling. A new study published in Nature npj Viruses, ...

Morbillivirus is a marine mammal virus related to human measles and smallpox. It’s the first strain of morbillivirus linked to Fraser’s dolphin. Researchers said the virus could threaten other dolphin ...

Giant viruses are remarkable for their large genomes, often rivaling those of small bacteria, and for having genes thought exclusive to cellular life. Most isolated to date infect nonmarine protists, ...
