Graphene, one of the most promising new materials to be developed in decades, isn’t much to look at. And it's no wonder why. Researchers discovered graphene, or one-atom-thick sheets of carbon ...

In chemistry, a single atom can make a huge difference in a molecule. Swap out one carbon atom for a nitrogen atom, and the way the drug molecule interacts with its target can dramatically change.

The goal of the activity is to build a carbon atom out of elementary particles (up quarks, down quarks, and electrons). On the left side of the activity's window sits the particle dispenser ...

Adding a carbon atom in the late stages of development can make new drugs cheaper. It's like renovating a building rather than building it from scratch," Sharma said.
