Just a few hundred light years from Earth, a swollen red giant is quietly forcing astronomers to rethink how stars seed the galaxy with the raw materials for planets and life. New observations of the ...

Most elements hungrily combine with all the oxygen they can find. So how could any free oxygen still remain to be floating ...

Layered double hydroxides (LDHs) are emerging as promising electrocatalysts for the oxygen evolution reaction (OER), a key barrier in clean hydrogen ...

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission ...

Water seems like an incredibly simple thing, right? Two hydrogen atoms and one oxygen atom combine to create the most essential element in the whole world. It’s what fills oceans, rivers, ponds, lakes ...

In work that melds the natural with the technological, he foregrounds entanglements shaped by looping currents of life, ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...

Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

The surprisingly high amounts of chlorine and potassium in a supernova remnant could help solve the mystery of where these crucial elements come from ...

Using the XRISM space telescope, scientists spotted faint emissions of the elements in remnants of the Cassiopeia A supernova ...

Some of the elements used by living systems are far more abundant in Cassiopeia A than we thought, hinting that some parts of our galaxy might be more suitable for life than others ...
