Carbon atoms move around the planet in a process known as the carbon cycle—but really, two carbon cycles are moving together at the same time. Here's how it works: While Earth's atmosphere is ...

NASA's Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The ...

Students use Snap Cubes to make models of atoms and molecules. They are given white, red, blue, and black cubes that represent hydrogen, oxygen, nitrogen, and carbon atoms respectively. Students are ...

Curiosity found large organic molecules in a 2013 Mars rock sample. These fragments suggest Mars had the right chemistry for ...

Researchers are opening up new horizons in chemistry: They present the world's first triple bond between the atoms boron and carbon. Boron, carbon, nitrogen and oxygen: these four elements can ...

It was discovered that atoms in pure silver are 200 times less ... Wicht added, “For each silver atom, the carbon background induces a two hundred times higher activity. This is, of course ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

The organic molecules found by Curiosity consist of carbon atoms linked in long chains, with other elements bonded to them, like hydrogen and oxygen. They come from a 3.7-billion-year-old rock ...
