Published Planted mangroves' ability to store carbon
(via sciencedaily.com)
Original source 
Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published A new twist on artificial 'muscles' for safer, softer robots
(via sciencedaily.com)
Original source 
Engineers have developed a new soft, flexible device that makes robots move by expanding and contracting -- just like a human muscle. To demonstrate their new device, called an actuator, the researchers used it to create a cylindrical, worm-like soft robot and an artificial bicep. In experiments, the cylindrical soft robot navigated the tight, hairpin curves of a narrow pipe-like environment, and the bicep was able to lift a 500-gram weight 5,000 times in a row without failing.
Published Mozambican Woodlands could store more than double the carbon previously estimated
(via sciencedaily.com)
Original source 
The capacity of Mozambican woodlands to capture and store carbon is underestimated and potentially undervalued for their protection and restoration, finds new research from an international team of scientists.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com)
Original source 
Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published Global database reveals large gaps in our knowledge of four-footed animals
(via sciencedaily.com)
Original source 
Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
Published Whale remains tracked to highlight sustainable disposal benefits
(via sciencedaily.com)
Original source 
A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com)
Original source 
A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com)
Original source 
A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Engine wear risk as planes swallow more dust waiting to land
(via sciencedaily.com)
Original source 
Planes flying into one of the world's busiest airports are ingesting around 10kg of dust per 1,000 flights.
Published Study reveals environmental impact of artificial sweeteners
(via sciencedaily.com)
Original source 
A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com)
Original source 
Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published Coral reefs: Battlegrounds for survival in a changing climate
(via sciencedaily.com)
Original source 
Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.
Published Exploring the radiative effects of precipitation on Arctic amplification and energy budget
(via sciencedaily.com)
Original source 
While, in theory, precipitation impacts the Earth's radiation budget, the radiative effects of precipitation (REP) are poorly understood and excluded from most climate models. Hence, a new study examined the role of REP in the global and regional energy budgets and hydrological cycles, finding that REP significantly contributes to temperature and precipitation variations at different geographical scales, especially in the Arctic warming. This highlights the relevance of including REP in climate modeling for improved accuracy.
Published Retreating glaciers: Fungi enhance carbon storage in young Arctic soils
(via sciencedaily.com)
Original source 
Melting Arctic glaciers are in rapid recession, and microscopic pioneers colonize the new exposed landscapes. Researchers revealed that yeasts play an important role in soil formation in the Arctic.
Published Climate change drives tree species towards colder, wetter regions
(via sciencedaily.com)
Original source 
Climate change is likely to drive tree species towards colder and wetter regions.
Published Clever clothes! Seams in clothing capture body movement
(via sciencedaily.com)
Original source 
Everyday clothing may soon be able to capture and record body movements according to new research.
Published Study illuminates cues algae use to 'listen' to their environment
(via sciencedaily.com)
Original source 
New research shows how a small group of single-celled algae are able to use chemical cues to communicate stress information. Understanding this ability, once thought unique to plants, helps illuminate the complex evolutionary history of plants and algae.
Published Ocean acidification turns fish off coral reefs
(via sciencedaily.com)
Original source 
A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species.
Published A prosthesis driven by the nervous system helps people with amputation walk naturally
(via sciencedaily.com)
Original source 
With a new surgical intervention and neuroprosthetic interface, researchers restored a natural walking gait in people with amputations below the knee. Seven patients were able to walk faster, avoid obstacles, and climb stairs more naturally than people with a traditional amputation.
Published New and improved camera inspired by the human eye
(via sciencedaily.com)
Original source 
Computer scientists have invented a camera mechanism that improves how robots see and react to the world around them. Inspired by how the human eye works, their innovative camera system mimics the tiny involuntary movements used by the eye to maintain clear and stable vision over time.
