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.

Shark fear: Just when you thought it was safe to get back in the water...      (via sciencedaily.com)     Original source 

It's one of the most famous taglines in film history, immortalizing sharks as ruthless predators. But beyond the horror generated by Spielberg's Jaws series, a persistent fear of sharks remains, with consequences that extend into reality.

North Atlantic's marine productivity may not be declining, according to new study of older ice cores      (via sciencedaily.com)     Original source 

To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. Analysis of a Greenland ice core going back 800 years shows that atmospheric chemistry, not dwindling phytoplankton populations, explains the industrial-era ice core trends.

A 'fish cartel' for Africa could benefit the countries, and their seas      (via sciencedaily.com)     Original source 

Banding together to sell fishing rights could generate economic benefits for African countries, which receive far less from access to their fisheries on the global market than other countries do from theirs. By joining forces, researchers say African fisheries would not just secure more competitive access fees, they could also protect their seas' biodiversity.

Tracking down quantum flickering of the vacuum      (via sciencedaily.com)     Original source 

Absolutely empty -- that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations. Experts are currently preparing a laser experiment intended to verify these vacuum fluctuations in a novel way, which could potentially provide clues to new laws in physics. A research team has developed a series of proposals designed to help conduct the experiment more effectively -- thus increasing the chances of success.

Endangered turtle population under threat as pollution may lead to excess of females being born      (via sciencedaily.com)     Original source 

Researchers find exposure to heavy metals cadmium and antimony and certain organic contaminants, accumulated by the mother and transferred to her eggs, may cause embryos to be feminized in green sea turtles (Chelonia mydas), a species already at risk of extinction from a current lack of male hatchlings.

quantum mechanics: Unlocking the secrets of spin with high-harmonic probes      (via sciencedaily.com)     Original source 

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of magnetic phenomena, and it's these spins that a team of researchers has learned to control with remarkable precision, potentially redefining the future of electronics and data storage.

Zooplankton in ocean and freshwater are rapidly escalating the global environmental threat of plastics      (via sciencedaily.com)     Original source 

A collaborative research team has recently revealed that rotifers, a kind of microscopic zooplankton common in both fresh and ocean water around the world, are able to chew apart microplastics, breaking them down into even smaller, and potentially more dangerous, nanoplastics -- or particles smaller than one micron. Each rotifer can create between 348,000 -- 366,000 per day, leading to uncountable swarms of nanoparticles in our environment.
