Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the ...

Reactive molecular oxygen singlets have a multitude of uses in chemistry and medicine, but they are less abundant than non-reactive oxygen triplets. A multinational research team has developed a novel ...

Photosynthetic bacteria do not release oxygen during photosynthesis but can convert solar energy into chemical energy with ...

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 ...

For the first time, the full biographical arc of a galaxy beyond our own has been reconstructed — not from light curves or ...

Astronomers have announced that they have detected molecular oxygen in a galaxy that's about half a billion light-years away from our galaxy. This is an important discovery because it's only the third ...

A subtle chemical trace locked inside ancient lunar samples is reshaping how scientists understand the Moon’s earliest ...

Trivalent titanium occurs only when the amount of oxygen available for chemical reactions is low. Thus, the abundance of ...
