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 ...

Peptide amidation is a ubiquitous posttranslational modification of bioactive peptides. Peptidylglycine α-hydroxylating monooxygenase (PHM; EC 1.14.17.3), the enzymne that catalyzes the first step of ...

In this study, chiral gold nanoparticles with a concave vortex cube structure were employed as the chiral substrate, exhibiting highly tunable optical chirality and intriguing chiral-induced spin ...

Oxygen atoms are highly reactive, yet the world does not spontaneously burn, even though everything is surrounded by this aggressive element. Why? The reason is that normal O2 molecules, are not ...

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 ...

We humans need oxygen to breath - for a lot of microbes it is a lethal poison. That is why microorganisms have developed ways to render oxygen molecules harmless. Microbiologists have now succeeded in ...

Oxygen plays a crucial role for all living organisms on Earth. Researchers at the University of Gothenburg have now found evidence that double ionised sulphur dioxide contribute to the formation of ...

A team of chemists at the Korea Advanced Institute of Science and Technology has succeeded in pulling an oxygen atom from a molecule and replacing it with a nitrogen atom. In their study, published in ...
