A deep-sea fish inspired researchers to develop supramolecular light-driven machinery      (via sciencedaily.com)     Original source 

Chemists have developed a bioinspired supramolecular approach to convert photo-switchable molecules from their stable state into metastable one with low-energy red light. Their work enables fast, highly selective, and efficient switching, providing new tools for energy storage, activation of drugs with light, and sensing applications.

Heat tolerant coral may trade fast growth for resilience      (via sciencedaily.com)     Original source 

Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. Researchers have now found that there was a tradeoff for corals dominated by the thermally sensitive algae -- they have higher growth, but only in cooler water.

Rediscovery of rare marine amoeba Rhabdamoeba marina      (via sciencedaily.com)     Original source 

Researchers have rediscovered and successfully cultivating Rhabdamoeba marina -- a rare marine amoeba that has only been reported in two cases in the past century. Using this culture strain, they performed a comprehensive analysis of its genetic sequence, revealing for the first time the phylogenetic position of this enigmatic amoeba, and proposed a novel taxonomic classification based on their research findings.

Much more than waste: Tiny vesicles exchange genetic information between cells in the sea      (via sciencedaily.com)     Original source 

Researchers take a look at data that has so far been mostly discarded as contamination, revealing the previously underestimated role of extracellular vesicles (EVs). These are important for the exchange of genetic information between cells and thus for the microbial community in the sea.

New study reveals huge potential for future waves of invasive species      (via sciencedaily.com)     Original source 

Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.

WhaleVis turns more than a century of whaling data into an interactive map      (via sciencedaily.com)     Original source 

A team has created an interactive dashboard called WhaleVis, which lets users map data on global whale catches and whaling routes from 1880 to 1986. Scientists can compare this historical data and its trends with current information to better understand whale populations over time.

Multiple evolutionary trajectories in aquatic crocodiles      (via sciencedaily.com)     Original source 

In the geological past, several groups of crocodiles evolved towards a morphology adapted to marine life. However, the extent of these adaptations and their evolutionary trajectories remained unknown. An exhaustive study of their morphology has now shed light on the evolutionary mechanisms at work, thanks to three-dimensional reconstructions.

Surveilling wetlands for infectious bird flu -- and finding it      (via sciencedaily.com)     Original source 

Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.

Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers      (via sciencedaily.com)     Original source 

Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
