Is the detection of gravity waves a reality with nowdays technology ? Are there recent news ?
Unfortunately gravitational waves have not been detected yet.
There is a number of Earth-bound detectors planned and already in operation (e.g. LIGO, Geo 600, Virgo, Nanograv and others). As for space-borne detectors, ESA works on Next Gravitational-Wave Observatory after NASA pulled out of LISA project in April 2011 due to funding problems. Joint NASA/ESA mission, LISA Pathfinder will launch in June 2013 testing technologies to be used by NGO.
Keep an eye on the pages and blogs of these projects if you'd like to stay up to date on their progress. Also, if gravitational waves are detected, the discovery will no doubt be announced here and even here.
