95. Scientists announce the discovery of an elementary particle that is postulated to make up the Higgs field and so explains why fundamental particles have mass.

Answer:
God Particle Found
Few things in science have enjoyed as much media attention as the Higgs boson, yet few scientific subjects in the media are understood as poorly by the general public. At its most basic level, the Higgs boson (or God Particle, as it was described in the 1993 book "The God Particle: If the Universe Is the Answer, What Is the Question?") explains why fundamental particles such as electrons have mass. Immediately after the Big Bang, fundamental particles were believed to have been weightless, and so moved at the speed of light. Shortly after the initial "bang", it was theorised that the Higgs field developed, introducing a drag on these particles, slowing them down. Meanwhile, the photon, which has no mass, was not affected by the Higgs field and so continued to travel at the speed of light (indeed it has been proposed that the photon may even be able to exceed this speed). The Higgs field was proposed to be made up of once theoretical particles called Higgs bosons, the existence of which were confirmed in 2013, almost fifty years after they were first proposed.
