Six months ago, somewhere in the tropical waters off the coast of Mexico, scientists began drilling into one of the most iconic geological features on Earth: the Chicxulub crater; the 66 million year old remnants of a deadly asteroid impact, thought to have contributed to the demise of dinosaurs and most other forms of life which inhabited the Earth at the time. Today we speak to Sonia Tikoo, Assi ...[Read More]

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]
