For life to develop on a planet, certain chemical elements are needed in sufficient quantities. Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store ...

New research from ETH Zurich challenges the long-held “follow the water” rule in the search for extraterrestrial life. Scientists argue that a planet’s habitability depends on a narrow chemical ...

Actinides are a group of heavy, radioactive elements that include uranium, plutonium, americium, curium, berkelium and ...

Beneath the calm waters of the South China Sea, the Dragon Hole plunges over 301 metres, hiding twisting tunnels, vanishing ...

Scientists developed a single-atom iridium catalyst that drives both water-splitting reactions on one electrode, using 98.5% less precious metal for cheaper green hydrogen.

Hydrogen fuel is a promising alternative to fossil fuels that only emits water vapor when used and could thus help to lower ...

Earth’s habitability may trace back to a precise chemical balance during its formation, one that kept life-critical elements from disappearing into the core or drifting into space.

Without the highly brilliant X-ray sources, the otherwise very weak signal would not have been measurable. While the reaction ...

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

For the modern technology leader, the quest for peak performance has traditionally been a matter of chemistry, an endless ...

Because permeation and plasma-induced degradation are continuous rather than episodic, their effects accumulate gradually.

Snowflakes, nature's tiny artworks, owe their six-sided symmetry to the hexagonal arrangement of water molecules in ice. As they fall through clouds, varying temperatures and humidity dictate their ...
