Deducing the properties of a new form of diamond

Simple model used to compute elasticity of newly synthesized glassy diamond.

Scientists visualize structure of key DNA repair component with near-atomic resolution

At the first hint of DNA damage, a protein known as an ATR kinase activates the cell's built-in repair system. Scientists have now imaged this protein at unprecedented resolution, and are beginning to understand its response to DNA damage.

Squeezing light into a tiny channel brings optical computing a step closer

By forcing light to go through a smaller gap than ever before, researchers have paved the way for computers based on light instead of electronics.
