Plane search \\\'picks up signal\\\'

A Chinese ship searching for the missing Malaysia Airlines plane in the southern Indian Ocean has picked up a pulse signal, Chinese media say. They say the signal has a frequency of 37.5kHz per second - the same as those emitted by the flight recorders. However there is no evidence so far that it is linked to MH370. Dozens of ships and planes have joined the search, with the operation moving into its most intensive phase before batteries on the data recorders fade. On Saturday the Haixun 01 - one of two Chinese ships in the area - picked up the signal at about 25 degrees south latitude and 101 degrees east longitude, according to BBC.
