Using computer simulations, researchers have shown that the oxygen molecule (O₂) is stable up to pressures of 1.9 terapascal, which is about nineteen million times higher than atmosphere ...

For the first time, astronomers have found molecular oxygen — the same gas humans need to breathe — in a galaxy outside the Milky Way. Oxygen is the third most common element in the cosmos, after ...

I think about oxygen a lot more than I used to. This is because I am studying a chemical defense that turns ordinary oxygen, the same old stuff we obtain from breathing air – the same stuff that is ...

Chemists have achieved a new feat in the realm of chemical design and synthesis: They've helped create the first example of a synthetic molecule, with an asymmetric oxygen atom as its centerpiece, ...

Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved. Their findings could alter our understanding of the Earth’s early atmosphere ...

Why does your favorite T-shirt fade over time in the sun? Why do you get sunburn and why does autumn herald with brown leaves? These questions all have one thing in common: the interplay between dye ...

There are many levels at which a scientific question can be answered. An answer that is quite satisfying to a scientist from one discipline may be totally unsatisfactory to a scientist from another.

Finding oxygen in an exoplanet’s atmosphere is a clue that life may be at work. On Earth, photosynthetic organisms absorb carbon dioxide, sunlight, and water and produce sugars and starches for energy ...
