The iPad app (also available as a physical book, only without all the interactive bits) is, to be fair, a little less comprehensive; after all, when you have some 118 identified chemical elements ...

Phosphorus is an element found in rocks and soil, but not air. It’s in molecules like DNA and RNA, your genetic blueprints, and ATP, the chemical energy you use to fuel your body. Alone, phosphorus is ...

It's difficult to overstate just how surprisingly early to the party this water may have been. “This suggests that water, the ...

Those elements combine with one another in endless amalgamations to create a vast array of molecules, which are the architecture, the building blocks, of everything around you.

If you want to make life as we know it -- chemical-based life based on Earth-like biochemistry -- you need a variety of ingredients. You need the raw elements themselves: the atomic nuclei that ...

Molecules are made when two or more atoms chemically bond together. Atoms from different elements can combine. When the atoms are from different elements, the molecule can also be called a compound.

The periodic table of elements was proposed in 1869, and thereafter became one of the cornerstones of the natural sciences. This table was designed to contain all the elements (atoms) found in nature ...

Discover the history, structure, and importance of the periodic table of elements, from Mendeleev’s discovery to modern scientific applications. When you purchase through links on our site, we ...

Nitrogen finally joins the elite tier of elements like carbon that can form neutral allotropes—different structural forms of a single chemical element. Researchers from Justus Liebig University, ...

Carbon. Carbon is the next most common element in the human body, making up 18% of the body by mass. Its role is mostly structural, forming the “backbone” of many organic molecules.

Small molecules have critical roles at all levels of biological complexity and yet remain orphans of the central dogma. Chemical biologists, working with small molecules, expand our understanding ...
