The 2nd International Network on Government Science Advice (INGSA) Conference. Science and Policy Making: towards a new dialogue. Booklet cover.

Last week, the EGU Science Policy Fellow packed her bags and flew to Brussels. Now this wasn’t to sample some of the fine beers Belgium has to offer, but to attend the 2nd International Network on Government Science Advice (INGSA) Conference. This conference, co-organised by INGSA and the European Commission, aimed to discuss the major principles needed for effective science advice to governments, ...[Read More]

Microbialites – structures which result from the interaction between microbes and sediments – have existed in the rock record since 3700 Ma ago until the present day. The presence of microbes in environments where mineral precipitation is prevalent, usually derives in the development of such chemical sedimentary structures. This can take place in marine, non-marine, and subterranean environm ...[Read More]

The Earth’s magnetic field extends from the core of the planet, right out to space. It is an invisible, butterfly-like, shield which protects us against the harmful particles ejected by solar flares. In addition, it guards us from atmospheric erosion and water loss caused by solar wind. But how do scientists study the Earth’s magnetic field when it can’t be see? Much of what is known results from ...[Read More]
