Artificial organelles

Artificial limbs have been around for centuries, and scientists have been working on artificial organs for decades. Now come artificial organelles... [more]

Memory effect promises better memory chips

Electric fields shift ions' positions in nanoscale electronic circuits, which changes the electrical resistance of the circuits. This memory resistance... [more]

Nano pine trees

When a nanowire grows with a twisted rather than straight crystal structure, it forms a nano-size pine tree structure. [more]

Process melds nanowires and chips

Cross a standard chipmaking technique with recently-developed ways of manufacturing nanowire circuitry and you have a way to mass-produce the tiniest of electronic devices. [more]

Light-linked dots

Quantum dots, which are tiny specks of semiconductor material that can hold a single electron, are promising candidates for chip-based quantum computer bits. Shining ultrashort laser pulses on a stacked pair of quantum dots... [more]

Photonic matchmaker

Single photons are great for communicating quantum information because they withstand the rigors of interacting with the environment, but this quality also means they don't easily interact with each other. [more]

The brain knows

"Physics is to the rest of science what machine tools are to engineering. A corollary is that science places power in our hands which can be used for good or ill. Technology has been abused in this way throughout the ages from gunpowder to atomic bombs."
- John Pendry, Imperial College London
