Illuminating the benefits of marine protected areas for ecotourism, and vice versa      (via sciencedaily.com)     Original source 

As California, the U.S. and the world work to make good on commitments to conserve 30% of oceans and lands by 2030, all strategies are on the table -- and under the microscope. When it comes to the ocean, one valuable tool is marine protected areas (MPAs), regions that are defined, designated and managed for long-term conservation. Among other benefits, MPAs protect habitats and promote species diversity. They also hold value for communities and industries.

Unsafe lead levels in school drinking water: new study IDs building risk factors      (via sciencedaily.com)     Original source 

Civil and environmental engineers have determined the factors that may help identify the schools and daycare centers at greatest risk for elevated levels of lead in drinking water. The most telling characteristic for schools in Massachusetts is building age, with facilities built in the 1960s and 1970s -- nearly a third of the facilities tested -- at the greatest risk for having dangerously high water lead levels.

Money to burn: Wealthy, white neighborhoods losing their heat shields      (via sciencedaily.com)     Original source 

White, wealthy neighborhoods in the LA area -- and likely around the world -- are about to start feeling the same heat that has plagued poorer, Hispanic neighborhoods for generations. A new study shows the protective effect of income has largely eroded over the past 40 years, as landscape plants can't keep up with the pace of climate warming.

Small marine creatures swimming in plastic chemicals not reproducing      (via sciencedaily.com)     Original source 

Plastic waste in the water might be stopping -- or interrupting -- some shrimp-like creatures from reproducing. In a unique study, the ability of 'shrimp like' creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.

Durable plastic pollution easily, cleanly degrades with new catalyst      (via sciencedaily.com)     Original source 

Found in fishing nets, carpet, clothing, Nylon-6 is a major contributor to plastic pollution, including ocean pollution. Now, chemists have developed a new catalyst that quickly, cleanly and completely breaks down Nylon-6 in a matter of minutes -- without generating harmful byproducts. Even better: The process does not require toxic solvents, expensive materials or extreme conditions, making it practical for everyday applications. In experiments, the new process recovered 99% of the polymer's building blocks, which can then be upcycled into higher-value products.

Brittle stars can learn just fine -- even without a brain      (via sciencedaily.com)     Original source 

We humans are fixated on big brains as a proxy for smarts. But headless animals called brittle stars have no brains at all and still manage to learn through experience, new research reveals. These shy marine creatures have no brain to speak of -- just nerve cords running down each of their five wiggly arms. But that seems to be enough to learn by association, researchers report.

600 years of tree rings reveal climate risks in California      (via sciencedaily.com)     Original source 

The San Joaquin Valley in California has experienced vast variability in climate extremes, with droughts and floods that were more severe and lasted longer than what has been seen in the modern record, according to a new study of 600 years of tree rings from the valley.

Blasts to clear World War II munitions could contaminate the ocean      (via sciencedaily.com)     Original source 

World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.

Greener solution powers new method for lithium-ion battery recycling      (via sciencedaily.com)     Original source 

Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on approaches that dissolve the battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process. This simple, efficient and environmentally-friendly solution overcomes the main obstacles presented by previous approaches.

A single Bitcoin transaction could cost as much water as a backyard swimming pool      (via sciencedaily.com)     Original source 

Cryptocurrency mining uses a significant amount of water amid the global water crisis, and its water demand may grow further. Researchers provides the first comprehensive estimate of Bitcoin's water use. He warns that its sheer scale could impact drinking water if it continues to operate without constraints, especially in countries that are already battling water scarcity, including the U.S.

Antarctic glacier retreating rapidly      (via sciencedaily.com)     Original source 

Scientists are warning that apparently stable glaciers in the Antarctic can 'switch very rapidly' and lose large quantities of ice as a result of warmer oceans.    Their finding comes after glaciologists used satellites to track the Cadman Glacier, which drains into Beascochea Bay, on the west Antarctic peninsula.

Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico      (via sciencedaily.com)     Original source 

Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.

Giant sea salt aerosols play major role in Hawai'i's coastal clouds, rain      (via sciencedaily.com)     Original source 

A new study from atmospheric scientists revealed that the coastline can produce up to five times the concentration of giant sea salt aerosols compared to the open ocean and that coastal clouds may contain more of these particles than clouds over the open ocean -- affecting cloud formation and rain around the Hawaiian Islands.

Recycled phosphorus fertilizer reduces nutrient leaching, maintains yield      (via sciencedaily.com)     Original source 

A promising new form of ammonium phosphate fertilizer has been field-tested. The fertilizer, struvite, offers a triple win for sustainability and crop production, as it recycles nutrients from wastewater streams, reduces leaching of phosphorus and nitrogen in agricultural soils, and maintains or improves soybean yield compared to conventional phosphorus fertilizers.
