Micromegas and GEM are widely used in current and future projects. The high radiation resistance and excellent spatial+time resolution make thenm invaluable. I will review the Micromegas detector used in current and future particle and nuclear physics experiments. I will give details on steps to reach picosecond resolution for LHC high luminosity upgrades. It is also used in CAST searching for axions, and this suggests other novel uses. A new type of detector consisting of a large spherical gas volume with central electrode and small spherical sensor giving proportional amplification will be described. The way is open to search for WIM Ps down to 100MeV/c^2. Results obtained with a low radioactivity detector operated in LSM will be presented. The next project NEWS -G is a larger detector consisting of a selected pure copper sphere of 1.5 metre diameter at SNOLAB . This will provide a larger volume than the current detector and reduced background. I will discuss detecting the neutrino-nucleus interaction, neutrinos from supernovae and a competitive double beta decay experiment.
