Pinging pipes could help to identify lead water lines without excavation      (via sciencedaily.com)     Original source 

A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.

Eight new deep-sea species of marine sponges discovered      (via sciencedaily.com)     Original source 

Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.

Viscose manufactured solely from recycled materials      (via sciencedaily.com)     Original source 

At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.

Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows      (via sciencedaily.com)     Original source 

The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.

Harmful 'forever chemicals' removed from water with new electrocatalysis method      (via sciencedaily.com)     Original source 

Scientists have developed new electrochemical approaches to clean up pollution from 'forever chemicals' found in clothing, food packaging, firefighting foams, and a wide array of other products. A new study describes nanocatalysts developed to remediate per- and polyfluoroalkyl substances, known as PFAS.

After decades of Arctic sea ice getting faster and more hazardous for transport, models suggest a dramatic reversal is coming      (via sciencedaily.com)     Original source 

Will ice floating in the Arctic Ocean move faster or slower over the coming decades? The answer to this question will tell us whether marine transportation can be expected to get more or less hazardous. It might also have important implications for the rate of ice cover loss, which is hugely consequential for Northern Indigenous communities, ecosystems, and the global climate system. While observational data suggest the trend has been towards faster sea ice speeds, climate models project that those speeds will slow down during the summer season. This contrast has led to some questions around the plausibility of the model projections.

We know the Arctic is warming -- What will changing river flows do to its environment?      (via sciencedaily.com)     Original source 

Scientists recently combined satellite data, field observations and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 years. As expected, the overall region will be warmer and wetter, but the details -- up to 25% more runoff, 30% more subsurface runoff and a progressively drier southern Arctic, provides one of the clearest views yet of how the landscape will respond to climate change.

Less ice in the Arctic Ocean has complex effects on marine ecosystems and ocean productivity      (via sciencedaily.com)     Original source 

Most of the sunlight reaching the Arctic Ocean is reflected to space by sea ice, effectively shielding ocean ecosystems from sunlight. As the Arctic sea ice continues its downward trend, larger areas of the ocean become exposed to sunlight for longer periods, potentially allowing more primary production on the seafloor. However, according to a new study, this anticipated increase in primary production does not seem to be occurring uniformly across the Arctic Ocean.

An evolutionary mystery 125 million years in the making      (via sciencedaily.com)     Original source 

Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.

Evolution-capable AI promotes green hydrogen production using more abundant chemical elements      (via sciencedaily.com)     Original source 

A research team has developed an AI technique capable of expediting the identification of materials with desirable characteristics. Using this technique, the team was able to discover high-performance water electrolyzer electrode materials free of platinum-group elements -- substances previously thought to be indispensable in water electrolysis. These materials may be used to reduce the cost of large-scale production of green hydrogen -- a next-generation energy source.
