Deep-sea mining and warming trigger stress in a midwater jellies      (via sciencedaily.com)     Original source 

The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

Microbiome development: Bacteria lay the foundations for their descendants      (via sciencedaily.com)     Original source 

The microbiome (the symbiotic community of microbial organisms of a host) is of existential importance for the functioning of every plant and animal, including human beings. A research team has now used the example of the sea anemone Nematostella vectenis to investigate how the microbiome develops together with the host. The researchers describe that the bacterial community is primarily controlled by the host organism during the early stages of life, while bacteria-bacteria interactions play the lead role in subsequent development.

Deep dive on sea level rise: New modelling gives better predictions on Antarctic ice sheet melt      (via sciencedaily.com)     Original source 

Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise.   The Antarctic ice sheet is the largest block of ice on earth, containing over 30 million cubic kilometers of water.   Hence, its melting could have a devasting impact on future sea levels. To find out just how big that impact might be, the research team turned to the past.

Putting an end to plastic separation anxiety      (via sciencedaily.com)     Original source 

Bio-based plastics often end up in recycling streams because they look and feel like conventional plastic, but the contamination of these compostable products makes it much harder to generate functional material out of recycled plastic. Scientists have now developed a biology-driven process to convert these mixtures into a new biodegradable material that can be used to make fresh products. The scientists believe the process could also enable a new field of biomanufacturing wherein valuable chemicals and even medicines are made from microbes feeding off of plastic waste.

Heat tolerant coral may trade fast growth for resilience      (via sciencedaily.com)     Original source 

Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. Researchers have now found that there was a tradeoff for corals dominated by the thermally sensitive algae -- they have higher growth, but only in cooler water.

Climate change effects hit marine ecosystems in multiple waves, according to marine ecologists      (via sciencedaily.com)     Original source 

A new approach to examining the effects of climate change on marine ecosystems may provide a more accurate understanding of climate change responses -- and predictions for future consequences -- according to a new article. The paper highlights the interplay between the trend of climate warming and the fluctuations in local temperature. These two properties cause atypically warm events such as marine heatwaves to occur with increasing frequency and magnitude.

Water splitting reaction for green hydrogen gas production improved      (via sciencedaily.com)     Original source 

Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
