A Geoscientist’s Colorful Journey from Research to Children’s Books
How the Earth Works digs into all that happens beneath our feet in an accessible and lively manner. The pages of this book are charged with Dr. Lucía Pérez-Díaz’s passion and expertise, as she helps us to explore the inner workings of our planet. (Credit: Ryan Cowan)

In today’s blog we’re having a chat with our very own Dr Lucia Perez-Diaz. As Lucia put it at the start of this year’s General Assembly, us scientists get to wear many “hats”, and she lives up to that statement. Besides a brilliant geoscientist, she is an incredible artist – also featured as last year’s artist in residence – and a budding press assistant! But more importantly, she is the author of ...[Read More]

Jupiter’s moon Io is the most volcanically active world in our solar system, with hundreds of volcanoes that constantly erupt on its ever renewing surface. Although Io always points the same side toward Jupiter in its orbit around the gas giant, two other Galilean moons, Europa and Ganymede, pull Io’s orbit into an irregularly elliptical one. Thus, in its widely varying distances from ...[Read More]

In the age of climate change, glaciers across the Arctic are melting, consequently reducing regional freshwater supplies and contributing to the ongoing rise in global sea levels. But how fast do they melt? And is it possible to predict that? A new study on the Xeitl Sit’ (LeConte) glacier in Alaska aims to answer these questions. The research group from Oregon State University, Harvard University ...[Read More]

Predators or gardeners: how penguins fertilise Antarctica’s biodiversity

Predators or gardeners: how penguins fertilise Antarctica’s biodiversity
Sea birds contribute importantly to biogeochemical cycles in coastal ecosystems and on islands. Feeding on the marine food chain and nesting on land, they carry large amounts of marine nutrients into terrestrial ecosystems. This might be of particular importance for the nitrogen (N) cycle of terrestrial ecosystems in the antarctic. Credit: Daniel Wasner (distributed via imaggeo.egu.eu)

On the desolate Antarctic peninsula, a colony of penguins creates a hub of biodiversity. One may ask, how exactly do those aquatic birds help maintain and enrich the variety of different kinds of organisms from plants and animals, to a wide range of insects and micro-organisms that live on our planet? The answer is quite intriguing. Scientists from the University of Science and Technology of China ...[Read More]
