The IST Students Association (AEIST) has restarted the edition of its journal Técnica. The first issue of this journal appeared in 1925 and it was published regularly until 1998, when it was discontinued. Now, the AEIST has decided it was time to restart its publication, see here for the new edition. There are several articles in this issue. One article is by José Sande Lemos, a CENTRA member, on the works of Mira Fernandes, a mathematician and mathematical physicist, who taught at IST since its foundation in 1911.

CENTRA researchers Ilídio Lopes and Jordi Casanellas have used the oscillations of nearby stars to put limits to the characteristics of the dark matter  particles, the elusive constituents of more than 80% of the total mass of the Universe. These results, to be published in The Astrophysical Journal Letters, show the potential of the present asteroseismic missions Kepler and CoRoT to investigate the nature of dark matter.
