Good news for coral reef restoration efforts: Study finds 'full recovery' of reef growth within four years      (via sciencedaily.com)     Original source 

While the majority of the world's reefs are now under threat or even damaged potentially beyond repair, a new study offers some encouraging news: efforts to restore coral reefs not only increase coral cover, but they can also bring back important ecosystem functions, and surprisingly fast.

Reptile roadkill reveals new threat to endangered lizard species      (via sciencedaily.com)     Original source 

The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.

Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks      (via sciencedaily.com)     Original source 

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'

Loss of nature costs more than previously estimated      (via sciencedaily.com)     Original source 

Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.

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.

Understanding wind and water at the equator key to more accurate future climate projections      (via sciencedaily.com)     Original source 

Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.

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.

Nanodevices can produce energy from evaporating tap or seawater      (via sciencedaily.com)     Original source 

Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.

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.

Research explores the cooling effects of 'scuba-diving' in lizards      (via sciencedaily.com)     Original source 

Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs, according to new research.

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.

Microalgae with unusual cell biology      (via sciencedaily.com)     Original source 

A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.

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.
