Whole-genome Sequencing Of Paenibacillus Phoenicis Isolated from the Phoenix Mars Lander Spacecraft Assembly Facility

by Keith Cowing

The genome of Paenibacillus phoenicis, a spore-forming bacterium isolated from the spacecraft assembly facility of the Phoenix mission, was generated via hybrid assembly by merging short and long reads. Examining […]

The Deep-ocean Floor Produces Its Own Oxygen

by Keith Cowing

An international team of researchers, including a Northwestern University chemist, has discovered that metallic minerals on the deep-ocean floor produce oxygen — 13,000 feet below the surface.
