An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only ...

You are taught early in science that oxygen on Earth comes from sunlight. Plants, algae, and cyanobacteria use light to split ...

Nearly 4,000 m beneath the Pacific, in water so dark that sunlight has never penetrated, scientists have stumbled on a new ...

It is common knowledge that there would be no oxygen on Earth were it not for sunlight; the key component in photosynthesis. Now researchers have made the surprising discovery that oxygen is also ...

Polymetallic nodules, collected from the ocean floor, sit in simulated seawater in chemist Franz Geiger's laboratory at Northwestern University. An international team of researchers, including a ...

Mitochondria are integral to cellular bioenergetics, utilising nutrient oxidation to drive ATP synthesis while concurrently generating reactive oxygen species (ROS), including superoxide and hydrogen ...

An international team of researchers has devised a plasma-based approach to producing oxygen on Mars to support exploration. Oxygen is vital: it breathable environments, life support, producing fuels ...

A toaster-sized device called MOXIE is tucked inside NASA's Perseverance rover, which landed on Mars in 2021. MOXIE reliably produces 6 grams of oxygen per hour under various conditions on Mars. A ...

Oxygen has been historically linked to sunlight. But a new study has suggested that oxygen may also be produced without any sunlight at all. Scientists at the University of Southern Denmark recently ...
