Imaginative research experiments receive millions

Associate Professor Christoffer Karoff from Geoscience is one of the recipients. He receives 2 million DKK for a project to construct a prototype for monitoring methane emissions from space. It is the Villum Experiment program that distributes the funds, where 19.7 million out of a pool of 99 million goes to the Faculty of Natural Sciences at AU.

Latest news about the origin of the Egtved girl

Erik Thomsen and Rasmus Andreasen respond to Robert Frei's commentary article. They show that the calculations Robert makes to support his arguments are based on an incorrect basis. When you instead use the best available estimates in the calculations, nothing in the strontium signatures indicates that the Egtved girl did not come from Egtved.

The primeval forests of the past and the biodiversity of today

Notions of the ecosystems of the past plays a major role in the debate on biodiversity. Professor emeritus Bent Odgaard and others document on the basis of measuring e.g. titanium in a borehole on Mols that the primeval forest before agriculture came was dense and not particularly affected by large grazers in contrast to theories of rewilding

From supernova to star dust - the mystery of Betelgeuse has been solved

Several astronomers believed that the giant star Betelgeuse was about to explode, but this was not the case. Instead, it was stardust that surrounded Betelgeuse. But the whole process around Betelgeuse is important in understanding the development - and also the origin of life - in the Universe, Christoffer Karoff says in the article. (In Danish)

What the ice can tell - field trip to Greenland

In north-eastern Greenland, there are unexplored areas when it comes to research into climate change and the marine environment. Now, a research project funded by the Independent Research Fund Denmark and led by Marit-Solveig Seidenkrantz, will create valuable knowledge about the region by using a new and unique data set.

Why is Mars red?

Associate Professor Emeritus Per Nørnberg from Geoscience answers that question in this article on Videnskab.dk. It is Bjørn, 5 years old, who asks the question, but the answer is not necessarily straightforward. Therefore, the article also contains both a simple and a complicated explanation. Read the article here. (In Danish)

Surprising hot-spot for metal pollution in prehistoric city

In prehistorical cities, metal pollution has been explained by mining activities and lead from water pipes, but a new international study of i.e. Søren Munch Kristiansen and Gry Hoffmann Barfod point out that smaller everyday activities in prehistoric cities must be included in order to understand the distribution of pollution.

New podcast on solar eclipses: When the Sun Disappears and Darkness Breaks Out

On Thursday, there is a partial solar eclipse over Denmark. Therefore, you can hear Associate Professor Christoffer Karoff talk about the different kinds of solar eclipses and about the corona of the sun in the ”RumSnak” podcast. Other topics are solar storms and how the solar cycle affects our atmosphere and also climate change. (In Danish)

Extreme CO2 greenhouse effect heated up the young Earth

Although sun radiation was relatively low, the temperature on the young Earth was warm. Important clues show that high levels of carbon dioxide in the atmosphere were responsible for these high temperatures. It only got cooler with the beginning of plate tectonics, as the CO2 was gradually captured and stored on the emerging continents.
