Mining of rare metals on deep sea and ocean floors miles below the surface could create "dark oxygen" and also cause potentially harmful changes to the marine ecosystem, according to new research.

A diver swims next to algae. Ecologists are keen to protect the sea bed, one of the planet's last untouched ecosystems, though companies see opportunity in rocks on the ocean floor which contain ...

Penn State researchers created seven new high-entropy oxides by removing oxygen during synthesis, enabling metals that normally destabilize to form rock-salt ceramics. Machine learning helped identify ...

Potato-sized lumps of metal on the seafloor are generating oxygen, a new study has found. Scientists previously believed that oxygen was strictly formed as a byproduct of photosynthesizing plants.

Scientists have developed tiny metal-oxide particles that push cancer cells past their stress limits while sparing healthy ...

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there. This ...
