Staying alive: sinking Trichodesmium fixes nitrogen in the dark ocean
Sunlight extinguishes about 150 m in the ocean, retaining photosynthetic microbes such as the diazotrophic cyanobacteria in the surface ocean layer. Here we find that Trichodesmium, a key photosynthetic diazotroph, fixes nitrogen while sinking into the deep ocean down to 1000 m depth.
The implications of the contamination of Arctic ice samples to future space missions to Europa and Enceladus
We developed a protocol that may be used to monitor and minimise the microbiological contamination of planetary field analogues of icy moons in their analysis. It may serve as a test-bed for procedures of decontamination of samples from future landing/return missions to icy moons.
What will it take to make aviation climate neutral?
Although currently left out of international climate agreements, the aviation sector - if left unmitigated - could jeopardize achieving the Paris agreement. We explored what climate neutrality means for the aviation sector and assessed the magnitude of the necessary efforts.
