RIKEN astrophysicists have performed the first laboratory experiments to see whether the interaction between dark matter and antimatter differs from that between dark matter and normal matter. If such a difference exists, it could explain two cosmological mysteries: why there is so little antimatter in the Universe and what is the true nature of dark matter (see page 18).
