Nano knitting mends brains
Scientists have used a nanotechnology-based technique to repair traumatic brain injuries in hamsters. The brain injuries blinded the animals; the repair partially restored the hamsters' vision...

Mighty molecular motor
Scientists have made several types of single-molecule rotary motors. The challenge is getting them to do useful work...

Broken straw illusion

View from the High Ground: Cornell's Jon Kleinberg
Six degrees of separation, buying gasoline by the molecule, the science of popularity, all just getting along online, intellectual prosthetics, Big Science, making up questions, and telling stories.

How It Works: Quantum computing: qubits
Photons, electrons and atoms, oh my! These particles are the raw materials for qubits, the basic building blocks of quantum computers.

DNA nanotech made easy
Scientists have produced two-dimensional patterns from DNA for several years, but the process is complicated and the yields are often low. A researcher from the California Institute of Technology has found a simple way to arrange DNA into just about any pattern that can be formed from 200 dots
