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.

Yucatán's underwater caves host diverse microbial communities      (via sciencedaily.com)     Original source 

With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'

How mega-floods can be predicted      (via sciencedaily.com)     Original source 

Extreme flood events are extraordinary outliers that were not considered possible on the basis of local data. However, if one considers the entire European continent, these local surprises are no longer surprising at all. If data from other regions with similar hydrological conditions is taken into account, the extent of these 'mega-floods' suddenly becomes predictable.

Greenland's glacier retreat rate has doubled over past two decades      (via sciencedaily.com)     Original source 

A new study documents how Greenland's peripheral glaciers have changed from 1890 to 2022. Using satellite images and a unique archive of historical aerial photos, researchers documented changes in the lengths of more than 1,000 of the country's glaciers over the past 130 years. Although glaciers in Greenland have experienced retreat throughout the last century, the rate of their retreat has rapidly accelerated over the last two decades.

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.

A different take on phosphorus: Bacteria use organic phosphorus and release methane in the process      (via sciencedaily.com)     Original source 

Some bacteria are able to tap into unusual sources of nutrients in the surface water of the oceans. This enables them to increase their primary production and extract more carbon dioxide from the atmosphere. In doing so, however, they release the potent greenhouse gas methane.

Device 'smells' seawater to discover, detect novel molecules      (via sciencedaily.com)     Original source 

Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.

Experiment shows biological interactions of microplastics in watery environment      (via sciencedaily.com)     Original source 

Scientists have learned over the years that when aquatic organisms such as zooplankton become exposed to microplastics, they eat poorly. Research now shows that their plastic-induced eating difficulties also limit the ability of zooplankton to control algal proliferation. When algae bloom out of control, this presents a problem because some species produce toxins. Also, algal blooms can be associated with pea-soupy, unattractive bodies of water and contribute to hypoxia, a low-oxygen condition that may lead to fish kills.

We can save lives and millions with less nitrate in drinking water      (via sciencedaily.com)     Original source 

Denmark could save lives and more than $300 million a year by reducing the amount of nitrate in its drinking water. An ever-growing body of research concludes that the amount of nitrate in some Danish boreholes increases the risk of colorectal cancer.
