#ZARM scientists have identified the #cyanobacterium strain Anabaena sp. PCC 7938 as a highly promising one for a life support system on #Mars 🔴. Fed with a simulant of Martian dust and atmosphere, the selected strain demostrated its ability to produce oxygen and form biomass, which could serve the production of food 🥔, fuels, drugs 💊 and other materials zarm.uni-bremen.de/en/in-focus

Researchers track how #iron deficiency disrupts #photosynthesis in crucial #ocean #algae
"Every other breath you take includes oxygen from the ocean, released from phytoplankton," said Paul G. Falkowski, the Bennett L. Smith Chair in Business and Natural Resources at Rutgers-New Brunswick and a co-author of the study. "Our research shows that iron is a limiting factor in phytoplankton's ability to make oxygen in vast regions of the ocean"

The #ocean’s most abundant #microbe is near its breaking point

Tiny ocean microbes called #Prochlorococcus, once thought to be #climate survivors, may struggle as seas warm. These #cyanobacteria drive 5% of Earth’s #photosynthesis and underpin much of the marine #food web. A decade of research shows they thrive only within a narrow #temperature range, and warming oceans could slash their #populations by up to 50% in tropical waters.
