Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new UCL-led research. Predicted by Einstein's general theory of relativity, gravitational waves are ripples in space-time generated by certain movements of massive objects.

An unusual gravitational wave signal is casting new light on the 'mass gap' between neutron stars and black holes. When the most massive stars die, they collapse under their own gravity and leave behind black holes.

New research has shown that microbubbles, which can be used to deliver drugs to remote parts of the body, can be manipulated by sound waves.

A highly unusual gravitational wave signal, detected by the LIGO and Virgo observatories in the US and Italy, was generated by a new class of binary systems (two astronomical objects orbiting around each other), an international team of astrophysicists has confirmed.
