Microscopic glass blowing used to make tiny optical lenses

Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature ...

Researchers design technology that sees nerve cells fire

Scientists have plenty of ways to watch as individual neurons in a brain fire, sending electrical signals from one to the next, but they all share a basic problem. Each method, whether it involves electrical probes, chemical ...

Scientists turbocharge high-resolution, 3-D imaging

You may not have heard of optical coherence tomography, or OCT. But if you've visited an ophthalmologist recently, chances are your eye came within an inch or two of a scanning device employing the technology. Tens of thousands ...

Precise molecular fingerprinting on the fly

Electro-optic modulators, which can switch light on and off within just picoseconds, are enabling ever faster telecommunication over optical glass fibres, so that large movies can be streamed more smoothly across oceans into ...
