Newly developed material logs and stores stress information of infrastructure      (via sciencedaily.com)     Original source 

A new material may be the key to quickly flag damaged infrastructure. This material offers a way to reduce the manpower required to regularly monitor structures that undergo daily use such as bridges. Compared to previous methods, this environmentally friendly material boasts the ability to operate without a power supply, and store information about previous incidents of mechanical stress. The application of this mechanoluminescent material is expected to make it easier and less costly to assess the safety of structures we may use in our everyday lives.

Pushing an information engine to its limits      (via sciencedaily.com)     Original source 

The molecules that make up the matter around us are in constant motion. What if we could harness that energy and put it to use? Over 150 years ago Maxwell theorized that if molecules' motion could be measured accurately, this information could be used to power an engine. Until recently this was a thought experiment, but technological breakthroughs have made it possible to build working information engines in the lab. Researchers have now teamed up to build an information engine and test its limits.

Scientists question effectiveness of nature-based CO2 removal using the ocean      (via sciencedaily.com)     Original source 

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialization of some approaches 'premature and misguided'. Scientists now review the climatic effectiveness of four 'nature-based' techniques using marine biological processes. These involve shellfish cultivation, seaweed farming, coastal blue carbon -- using the restoration of seagrass, saltmarsh and mangrove forests -- and increasing whale populations through 're-wilding'.

Exploring three frontiers in marine biomass and blue carbon capture      (via sciencedaily.com)     Original source 

A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom.

Rocky shores of Pacific Northwest show low resilience to changes in climate      (via sciencedaily.com)     Original source 

A 15-year period ending in 2020 that included a marine heat wave and a sea star wasting disease epidemic saw major changes in the groups of organisms that live along the rocky shores of the Pacific Northwest.

Microscopic defects in ice shape how massive glaciers flow, study shows      (via sciencedaily.com)     Original source 

A glacier's flow depends on how microscopic defects move through the ice, according to new research that also yielded a new model for predicting how glaciers will flow, ultimately contributing to sea-level rise.

Shape and depth of ocean floor profoundly influence how carbon is stored there      (via sciencedaily.com)     Original source 

The movement of carbon between the atmosphere, oceans and continents -- or carbon cycle -- regulates Earth's climate, with the ocean playing a major role in carbon sequestration. A new study finds that the shape and depth of the ocean floor explain up to 50% of the changes in depth at which carbon has been sequestered there over the past 80 million years. While these changes have been previously attributed to other causes, the new finding could inform ongoing efforts to combat climate change through marine carbon sequestration.

Fungus breaks down ocean plastic      (via sciencedaily.com)     Original source 

A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers expect that many more plastic degrading fungi are living in deeper parts of the ocean.

Historic iceberg surges offer insights on modern climate change      (via sciencedaily.com)     Original source 

A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.

Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years      (via sciencedaily.com)     Original source 

A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.

Breakthrough discovery uses engineered surfaces to shed heat      (via sciencedaily.com)     Original source 

Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface. The temperature at which this phenomenon, called the Leidenfrost effect, occurs is predictable, usually happening above 230 degrees Celsius. A team has now discovered a method to create the aquatic levitation at a much lower temperature.
