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 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]

Celebrating Earth Science Week!

Laura Roberts-Artal October 6, 2016

For those not so familiar with the Earth sciences, geosciences and all its subdisciplines might be shrouded in mystery: boring, unfathomable, out of reach and with little relevance to everyday life. Nothing could be further from the truth! Earth Science Week, an international annual celebration founded by the American Geosciences Institute in 1998, aims to change the public’s perception of the ge ...[Read More]

Imagine you find yourself standing atop a wooden box in the middle of your home town, on a rainy weekend day, with the sole aim of talking to passersby about your research work. It can be a rather daunting prospect! How do you decide what the take-home message of your work is: which single nugget of information do you want members of the public to take away after having spoken to you? Even more im ...[Read More]
