Washington State University physicists have created a fluid with
negative mass, which is exactly what it sounds like. Push it, and unlike
every physical object in the world we know, it doesn't accelerate in
the direction it was pushed. It accelerates backwards.

Not enough information is given in this experiment to arrive at a conculsion of "negative mass". For example, when a second laser is directed at a flask of super cooler atoms, the energy entering the atoms acks like a spring - releasing pent up energy from the laser. This then accelerates in a directioin which appears to be opposite that it should thus creating the effect of a "negative mass". If it were truely negative mass, it would float away from the Earth before getting hit with that second laser beam.
