DNA-nanotube combo spots toxins
Medical diagnostics and biomedical research are poised to benefit from nanosensors that combine DNA's sensitivity to specific substances and nanotubes' electrical and optical sensitivity to the environment

Self-improving software
If people are expected to learn on the job, why isn't software? Although some kinds of software are capable of learning, it's more difficult to design software that learns as it works without requiring a separate training process...

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.
