Sustainable protection of rapidly subsiding coastlines with mangroves      (via sciencedaily.com)     Original source 

Along the Asian coast lines there are many areas where rural communities experience alarming rates of sea level rises due to land subsidence up to 10 cm per year. This causes tremendous challenges on how to live there and protect these coasts. Scientists have now investigated the potential and limitation of mangrove restoration as a cost-effective and sustainable solution for coastal protection in rapidly subsiding areas.

Did animal evolution begin with a predatory lifestyle?      (via sciencedaily.com)     Original source 

Surprising findings on the development of sea anemones suggest that a predatory lifestyle molded their evolution and had a significant impact on the origin of their nervous system. The researchers were able to show that the young life stages (larvae) of the small sea anemone Aiptasia actively feed on living prey and are not dependent on algae. To capture its prey, the anemone larvae use specialized stinging cells and a simple neuronal network.

Whales Around the World Play With Kelp Clumps      (via sciencedaily.com)     Original source 

A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.

Atlantic walrus more vulnerable than ever to Arctic warming      (via sciencedaily.com)     Original source 

Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.

New qubit circuit enables quantum operations with higher accuracy      (via sciencedaily.com) 

Researchers have developed a novel superconducting qubit architecture that can perform operations between qubits with much higher accuracy than scientists have yet been able to achieve. This architecture, which utilizes a relatively new type of superconducting qubit called fluxonium, is scalable and could be used to someday build a large-scale quantum computer.

Theories about the natural world may need to change to reflect human impact      (via sciencedaily.com) 

New research has validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems.

Rivers contain hidden sinks and sources of microplastics      (via sciencedaily.com)     Original source 

New research represents the first combined analysis of microplastics in water, sediment and air around a major river system. It found significant quantities of microplastics trapped in riverbed sediments, and also found they were being transported through the air and the flow of the river.

Ocean acidification makes ecologically important seaweed species fragile      (via sciencedaily.com)     Original source 

Ocean acidification will likely almost triple by the end of the century -- a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century. They report that increased acidification impacted the seaweed's chemical balance, made both its structure and its tissues weaker, and reduced its overall chances of survival.
