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.

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.

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.
