Science for a Better World

We have previously expressed ISSI’s concern about the invasion of Ukraine and the resulting humanitarian crisis. The need to maintain science as a platform for dialogue even in times of conflict has become more prominent. As this war continues and other tensions rise around the world, it seems more important than ever to maintain institutions where such peaceful and constructive dialogue can take place. Science is a universal language that knows no geographical or political boundaries, nor boundaries related to race, gender or sexual orientation.

ISSI provides an open and neutral environment where such open and free discussions about Space and Earth Science, and related fields can take place. Dialogue between scientists promotes not only better science, but also a better mutual understanding among people of different origins and cultures. At ISSI we like to think of this as our own small contribution to a better world.

Rumi Nakamura and Geraint Jones appointed as ISSI Discipline Scientists

ISSI is pleased to announce that Dr. Rumi Nakamura and Prof. Geraint Jones have been appointed as Discipline Scientists as of 1st July 2023. We welcome two outstanding additions to the ISSI Team: Plasma Discipline Scientist Dr. Rumi Nakamura, and Planetary Discipline Scientist Prof. Geraint Jones. Not only Discipline Scientists provide scientific expertise that is complementary to the current ISSI portfolio, but, most important, they are ISSI Ambassadors with their unique communities. As such, they will  channel ideas and develop scientific initiatives that will best  serve their community, while at the same time explore ways to identify how best ISSI can advance  the scientific discourse in their respective fields.

JWST Opens New Scientific and Collaborative Avenues at ISSI

Last July scientists and journalists gathered at ISSI to celebrate the unveiling of the first JWST images and spectra. On this occasion Willy Benz, the new chair of ISSI’s BoT, anticipated that JWST would be an observatory that everyone will want to use. The ISSI community is certainly no exception in this respect, with at least two ISSI International Teams securing JWST observing time this spring.
