Diversity of novel hydrothermal vent styles on the Arctic ocean floor

A new study about Earth's northernmost seafloor hydrothermal system shows even more variety in vent styles than previously thought. The study has important implications for understanding the origin of these vents and assessing their global-scale impact on the Earth-Ocean system. The study also has implications for understanding and searching for habitable environments, and potentially even life on other ocean worlds in our outer solar system, according to the study's authors....

Are particle emissions from offshore wind farms harmful for blue mussels?

After several years of service under harsh weather conditions, the rotor blades of offshore wind parks are subjected to degradation and surface erosion, releasing sizeable quantities of particle emissions into the environment. A team of researchers has now investigated the effects of these particle on blue mussels -- a species also being considered for the multi-use of wind parks for aquaculture. Read more ›

New study highlights the correlation between live corals and fishing yields

A new study examines the correlation between fish yield and live coral habitats. Researchers analyzed the yields of nine fisheries dependent on Australia's Great Barrier Reef from 2016 to 2020. Results show that substantial losses could occur if the restoration of coral reefs is not prioritized. Read more ›

New evidence exists for hidden water reservoirs and rare magmas on ancient Mars

A new study explores how variations in Mars' crustal thickness during its ancient history may have influenced the planet's magmatic evolution and hydrological systems. The research suggests that the thick crust of Mars' southern highlands formed billions of years ago generated granitic magmas and sustained vast underground aquifers, challenging long-held assumptions about the red planet's geological and hydrological past.

Chart of life extended by nearly 1.5 billion years

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The chart shows the relative ups and downs in species counts, telling scientists about the origin, diversification, and extinction of ancient life. With this new study, the chart of life now includes life forms from the Proterozoic... Read more ›

Study shows role of cells' own RNA in antiviral defense

A new role has been uncovered for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune responses against virus invasion. With RNA increasingly seen as both a drug and a druggable target, the new findings open the potential for RNA-based therapeutics for combating both infection and... Read more ›

Role 'workhorse protein' plays in keeping the nervous system running smoothly

A team of researchers shows how proteins called 'chaperones' are vital in ensuring that neurons can transmit signals to one another. When this neurotransmission breaks down, devastating diseases such as Alzheimer's and Parkinson's along with many others, can occur. The team's research provides new understanding of how the most crucial part of the process works and is a stepping stone toward understanding the underlying mechanics of neurodegenerative diseases.
