In prehistoric times, the large animals inhabited most of the world, and new research now shows that they had greater importance for the function of the ecosystems than previously assumed. This provides greater understanding of why it is so important to include the large animals in nature management now and in the future. A bison herd is shown here in the Yellowstone National Park.

Extinction of the large animals has major consequences

The prehistoric megafauna – the large animals that inhabited both land and water – had greater importance for the function of the ecosystems than previously assumed, and their extinction has therefore had serious ecological consequences for the Earth. International research with the participation of Aarhus University focuses on the importance of…

Unique pump in sperm cells makes a difficult journey possible

A prerequisite for the sperm cell’s difficult journey from the testes to the fallopian tube is its unique sodium-potassium pump. New studies of the unique pump show how it differs from the sodium-potassium pumps in the rest of the body, and gives hints on why sperm cells have developed their own pump.

Gong, snap and post a newborn baby at one and the same time

For several months, new parents at Aarhus University Hospital have been able to ring the ‘birth gong’ at Dokk1 (part of the Urban Mediaspace Aarhus project) at the touch of a screen. Two Aarhus University students have refined an app that makes it possible for the newborn baby to be photographed and make his or her first appearance on the…

‘The Sailing University’

The research vessel Aurora is visiting Vejle, Fredericia, Middelfart and Aabenraa. Taking part in the expedition between the towns are upper secondary school pupils enrolled in different courses. Here they are learning about navigation, surveying the sea bed, astronomy and a number of other science subjects. Welcome aboard ‘The Sailing…

Members of the audience not only attended a lecture, but also took part in a TV production. While the programme was transmitted from the DR Concert Hall, host Carsten Ortmann presented the three researchers on stage in Aarhus – Professor Emeritus Helge Kragh, Professor Hans Kjeldsen and Associate Professor Casper Andersen.

In connection with the event, Aarhus University had a full-scale model specially made of the TESS satellite to be launched in 2017, as well as a number of models of exoplanets the way the researchers imagine they appear. Here Professor Hans Kjeldsen is talking about exoplanets. He has previously given a public lecture entitled ‘On a space safari among the planets of the Milky Way’. (Photo: Christina Troelsen)
During the last part of the programme in Aarhus only, where there was also an opportunity to ask questions, Research Assistant Mads Fredslund Andersen showed how to use an ordinary Internet connection to remotely control Aarhus University’s SONG robotic telescope, which was inaugurated on the island of Tenerife a year ago.

An afternoon with P1liveX

While the autumn sun was shining outside the Lakeside Lecture Theatres on Sunday afternoon, the focus inside the building was on something far outside our solar system. The audience consisted of five hundred Aarhus residents when the Danish Broadcasting Corporation (DR) transmitted a live programme from Aarhus University in collaboration with the…

This illustration shows how our planet’s atmosphere is illuminated by the Sun, making it possible to see bioindicators. This light could be detected on the surface of the Moon during the autumn eclipse. (Illustration: Stellar Astrophysics Centre, Aarhus University)
The red glow of the Moon concealed valuable data for the physicists, who were able to find information from our atmosphere. In a way, the Earth was virtually a slide that could be seen on the surface of the Moon during the eclipse. (Photo: Tina Temkiv)

There’s life on Earth!

Indeed. We knew that. However, in the search for life in other parts of the universe, it is important to know what planets look like from a distance when there is life on them. The recent lunar eclipse helped astrophysicists gain insight into this – Earth has now been seen from ‘outside’.

Send a greeting to your cosmic neighbour

Yes, it’s true. Aarhus University is going to put through a ‘phone call’ to a planetary system with potentially habitable planets, which means you can send a message to our ‘neighbours’ in the universe. This will take place at the Lakeside Lecture Theatres in Aarhus on Sunday 25 October. The public is welcome to join this space safari.

Cause of viral infection of the brain mapped out

Researchers have discovered a defect in the immune system that causes some people with herpes virus to develop a life-threatening inflammation of the brain. This immunodeficiency is likely the same for certain types of meningitis and also the reason why some people become seriously ill due to influenza.

Narwhals dive to a depth of 2,000 metres and often frequent poorly accessible areas, but transmitters mounted on the animals reveal not only how far they swim and how deep they dive, but also how often they consume food while they are submerged. You can find more information about narwhal migration (in Danish and Greenlandic only) at niki.gl. (Photo: Wikimedia Commons)

New website about migratory animals in and around Greenland

A new website – niki.gl – contains articles about land and marine mammals and seabirds that have been tagged with electronic transmitters in Greenland. A summary of all studies carried out since 1993 is also included. The website was developed in collaboration between Aarhus University, the Greenland Institute of Natural Resources and the…

Danish finalists ready for the World Robot Olympiad (WRO)

The World Robot Olympiad – WRO 2015 – will be held in Qatar this November. Entrants from Denmark were selected at the Danish final, which was held at the Department of Computer Science, Aarhus University.

New technology can reduce traffic jams

Researchers are now taking a new step towards more intelligent traffic management. Individual motorists will reach their destination faster, cheaper and greener. The flow of traffic will be optimally distributed on the roads, and all the coordination will be automatic and wireless via GPS systems in the cars.

Increasing content of copper and zinc in agricultural soil

During the period 1986–2014, the concentration of copper and zinc in the soil increased due to spreading pig slurry. If this continues, it could eventually endanger organisms in the soil and water environment. Read more (in Danish only) here.
