Avoiding a crunch p417
doi:10.1038/nphoton.2015.120
Fears of an imminent capacity crunch in optical networks may be alarmist
but new more efficient technologies for transporting data will be required
in the future.

it crunch time? pp424 - 426
Rachel Won
doi:10.1038/nphoton.2015.114
As the demand for data transmission escalates and optical fibre capacity

Detection of X-ray photons by solution-processed lead halide perovskites pp444 - 449
Sergii Yakunin et al.
doi:10.1038/nphoton.2015.82
Solid-state X-ray detectors have enabled real-time diagnostics as well
as reduced patient dose. Now researchers have shown that potentially
inexpensive perovskites can be used for efficient X-ray imaging.
