Vitamin B12 adaptability in Antarctic algae has implications for climate change
Vitamin B12 deficiency in people can cause a slew of health problems and even become fatal. Until now, the same deficiencies were thought to impact certain types of algae, as well. A new study led by former MIT CBIOMES postdoc Deepa Rao examined the algae Phaeocystis antarctica’s (P. antarctica) exposure to a matrix of iron and vitamin B12 conditions. Results show that this algae can survive without B12, something that computer analysis of genome sequences had incorrectly indicated.

Ocean microbes get their diet through a surprising mix of sources, study finds
Up to one-third of the carbon consumed by Prochlorococcus may come from sources other than photosynthesis. Continue reading Ocean microbes get their diet through a surprising mix of sources, study finds
Small eddies play a big role in feeding ocean microbes
Swirling waters replenish nutrients in open ocean, a new study finds, and could mitigate some climate change effects. Continue reading Small eddies play a big role in feeding ocean microbes
