Leave a Comment / Genetics / By

A new study by researchers at the Bigelow Laboratory for Ocean Sciences suggests that a small fraction of marine microorganisms are responsible for most oxygen consumption and carbon dioxide release in the ocean. The startling discovery, published in Nature, comes from a new method that provides unprecedented insight into those organisms that help govern the …

The amount of oxygen in Earth’s atmosphere makes it a habitable planet. Twenty-one percent of the atmosphere is made up of this life-giving element. But in the distant past – as far back as the Neoarchean era 2.8 to 2.5 billion years ago – this oxygen was almost absent. So how did the Earth’s atmosphere …
