New Zealand scientists have designed a machine which they say can predict strokes and earthquakes.

It's called the NeuCube, and is designed to process complex data such as radio, brain and seismic signals.

AUT University's Dr Nik Kasabov says it's modelled on the human brain.

Using comparisons between scans of healthy brains and people who've had a stroke, the device is reckoned to be 95-percent accurate.
