Let \  be a knot in a rational homology sphere \  . Then there is a unique surgery on \  which results a manifold with \  \  \\   . We call this surgery the null surgery. When \  is an L-space, the null surgery remembers the information about the genus and fiberedness of the knot. A special case of our theorem is that if the resulting manifold is \  \  \ \  \    , then the dual knot is a spherical braid. This is joint work with Faramarz Vafaee.
