pulse

Central to this innovation is the ytterbium thin-disk laser, which produces high-power, femtosecond pulses at megahertz repetition rates.

The team hoped to use the light pulses to prevent the bursts by switching off neurons that contained light-sensitive proteins.

A theoretical astrophysicist from the University of Kansas may have solved a nearly two-decade-old mystery over the origins of an unusual "zebra" pattern seen in high-frequency radio pulses from the Crab Nebula.

Those pulses passed through transceivers, encountered the sandpapers, then rebounded back through the system for analysis by the team's learning model.

However, medics in the intensive care unit were then unable to find a pulse, and Mrs Savage was pronounced dead in the early hours of the morning.
