Space is home to a great many oddities, and even chemistry gets strange out there. In fact, there are even some molecules that you'd never find here on Earth.

When atoms of two or more elements bond together, they make a compound. These clusters of strongly bonded atoms are called molecules. See how they're represented by two circles of different size ...

The atoms of some elements, like copper, do not join together and instead exist on their own as individual atoms and are not molecules. The atoms of other elements, however, like hydrogen ...

Chemical biologists, working with small molecules, expand our understanding of these central elements of life. Chemical biologists have differing views of the defining features of our field.

Using basic molecules of elements like benzene and sulphur, the same scientists in 2010 figured out a way to make molecules that self-replicate, like DNA can. That inspired the researchers to ...

The image also highlights chemical modifications (yellow) that increase durability, and biotin molecules that help anchor the aptamers to surfaces or other molecules in sensors and assays. (Image: ...
