Panning for gold at the K stream
Article Abstract:
Scientists at Brookhaven National Laboratory have linked with colleagues in the US, Canada and Japan to observe a decay mode of the positive K meson that occurs around once in 10 billion decays. It has been possible for the first time to identify the decay of a positively charged K into a positively charged pi meson, a neutrino and an antineutrino. This research is particularly significant for testing the Standard Model of the interactions between the different fundamental particles.

Liberating quarks and gluons
Article Abstract:
Experiments undertaken in 1997 have produced the first strong evidence that a significant change occurs in the structure of nuclear matter when extremely high temperatures are achieved during collisions between high-energy heavy nuclei. These findings are the first that sceptical theorists have been unable to explain without making reference to a quark-gluon plasma. It remains uncertain whether the transition from normal matter to quark-gluon plasma is continuous or abrupt.

When words fail
Article Abstract:
Issues are presented concerning the lack of common words which can be used by scientists to describe several central concepts of science. The difficulties encountered by scientist Albert Einstein in defining 'now' are discussed.
