Mitigating climate change through restoration of coastal ecosystems      (via sciencedaily.com)     Original source 

Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.

Extreme precipitation in Northeast US to increase 52% by the end of the century      (via sciencedaily.com)     Original source 

With a warmer climate creating more humid conditions in the Northeast, extreme precipitation events -- defined as about 1.5 or more inches of heavy rainfall or melted snowfall in a day -- are projected to increase in the Northeast by 52% by the end of the century, according to a new study.

The next generation of solar energy collectors could be rocks      (via sciencedaily.com)     Original source 

The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.

Quarter-ton marsupial roamed long distances across Australia's arid interior      (via sciencedaily.com)     Original source 

One of Australia's first long-distance walkers has been described after palaeontologists used advanced 3D scans and other technology to take a new look at the partial remains of a 3.5 million year old marsupial from central Australia.   They have named a new genus of diprotodontid Ambulator, meaning walker or wanderer, because the locomotory adaptations of the legs and feet of this quarter-tonne animal would have made it well suited to roam long distances in search of food and water when compared to earlier relatives.

Saving our soil: How to extend US breadbasket fertility for centuries      (via sciencedaily.com)     Original source 

The Midwestern United States has lost 57.6 billion tons of topsoil due to farming practices over the past 160 years, and the rate of erosion, even following the U.S. Department of Agriculture's guidelines, is still 25 times higher than the rate at which topsoil forms. Yet, we need not despair: researchers recently reported that no-till farming, which is currently practiced on 40 percent of cropland acres in the Midwest, can extend our current level of soil fertility for the next several centuries. This has implications for everything from food security to climate-change mitigation.

Global macrogenetic map of marine habitat-forming species      (via sciencedaily.com)     Original source 

Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.

Engineers harvest abundant clean energy from thin air, 24/7      (via sciencedaily.com)     Original source 

A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.

New method predicts extreme events more accurately      (via sciencedaily.com)     Original source 

A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.

Move over, armadillos: There's a new bone-plated mammal in town      (via sciencedaily.com)     Original source 

Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.

Nontraditional water sources can be deployed to help cope with climate-induced water risks and tackle the increasing water demand for decarbonization of fossil fuel-fired power plants, but that could increase the cost of electricity generation by 8 percent to 10 percent.

How a drought affects trees depends on what's been holding them back      (via sciencedaily.com)     Original source 

Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.

Identifying the bee's knees of bumble bee diets      (via sciencedaily.com)     Original source 

A new study has identified the bee's knees of bumble bee dietary options in Ohio and the Upper Midwest. By viewing almost 23,000 bumble bee-flower interactions over two years, researchers found that these bees don't always settle for the most abundant flowers in their foraging area -- suggesting they have more discerning dietary preferences than one might expect.
