Do some mysterious bones belong to gigantic ichthyosaurs?      (via sciencedaily.com)     Original source 

Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.

Bacteria in cancer unmasked      (via sciencedaily.com)     Original source 

Researchers have compiled a detailed catalogue of bacteria living in cancer metastases. Having analyzed over 4000 tumors, they shed light on the diversity of these co-inhabitants and how they might interact with cancer cells and their surroundings. For example, certain bacteria were linked to a worse response to immunotherapy. This study paves the way to a better understanding of how bacteria help or hinder cancer (therapy), and how we can use this for patients' advantage.

eDNA methods give a real-time look at coral reef health      (via sciencedaily.com)     Original source 

The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.

What four decades of canned salmon reveal about marine food webs      (via sciencedaily.com)     Original source 

Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.

Adult fish struggle to bounce back in marine protected areas      (via sciencedaily.com)     Original source 

Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.

New tools reveal how genes work and cells organize      (via sciencedaily.com)     Original source 

Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.
