Here is the measurement that showed that the theories are consistent with the realities. The figure shows a single layer of the material molybdenum disulphide and a measurement of its electron structure (in black and white). A visualisation of the spin polarisation theory is shown at left in red and blue – the actual measurement in the material is shown at right. The polarisation can be seen as splitting in the measurement, marked with arrows. (Illustration: Philip Hofmann, Aarhus University)

Let the electrons spin!

The next generation of electronics needs new materials. Researchers at Aarhus University have now not only succeeded in doing away with the wrong assumptions about these material properties, but have also contributed to moving from an ambitious theory to tangible physics, where two-dimensional materials could ultimately create a platform for the…

The recent history of the pink-footed goose is in many ways a nature conservation success story that has turned into a nature conservation nuisance.

Breakthrough for European nature management

Promoting the interests of agriculture and protecting nature are often conflicting agendas. But it doesn’t have to be this way: as the first European experiment with adaptive management of the pink-footed goose shows, government authorities, researchers, hunters, farmers and nature conservation societies can actually work together effectively and…

New partnership will create growth in East Jutland

Science and Technology, Aarhus University, and the Aarhus City Council have just signed a contract that will strengthen the interaction between the business sector, the council and the university. Innovative projects in the area of the environment will create growth and more jobs in East Jutland.

Wolves in Denmark are still most often strays that do not stay in the area for several seasons. Only one wolf has been shown to have settled, and this was in Central Jutland. Photo: Bo Skaarup, Natural History Museum (in agreement with Scandinavian Wildlife Park).

New wolves visit Denmark

Later today, Senior Researcher Liselotte Wesley Andersen and Senior Researcher Thomas Secher Jensen will present the results of the latest DNA analyses of wolf samples from 2014 at the Biodiversity Symposium at Aarhus University. The results show that a further six individuals were detected in 2014, in addition to the eleven known wolves from 2013.

Five planets very closely orbit Kepler-444. They are all smaller than Earth. The star’s brightness is slightly reduced when they pass, and that is how we know they are there. This is a visualisation. (Illustration: Tiago Campante and Peter Devine)

The oldest planetary system found to date in the Milky Way

The oldest known planetary system has been discovered around the star Kepler-444. This is the result of calculations of data from the Kepler satellite by scientists including Aarhus astronomers. The discovery has just been published in The Astrophysical Journal.

Climate change redistributes fish species at high latitudes

For millions of years, large parts of the marine biotas of the North Atlantic and North Pacific have been separated by harsh climate conditions in the Arctic. A new study, just published in Nature Climate Change, underlines that climate change has begun to weaken this natural barrier promoting the interchange of fishes between the two…

A new SAGA of the formation and development of the Milky Way

One of our young astronomers – Víctor Silva Aguirre, Stellar Astrophysics Centre, Aarhus University – has received a grant that will give him the opportunity to dig deep into the past of the Milky Way.

Image at left with black background: In the eye of a transgenic mouse, a single motion-sensitive visual cell in the retina (green) has highlighted the neighbouring visual cells it is in contact with (purple). This was achieved by infecting it with a specially modified virus that can only cross from one neuron to another that it is in contact with (Yonehara et al., <em>Nature</em>, 2011). (Both images: Keisuke Yonehara)
Image at right with blue background: The calcium level is an expression of the activity of bipolar cells and motion-sensitive visual cells. The calcium is measured by expressing an intracellular calcium sensor (GCaMP3) in them. The activity in a nerve terminal (purple circle) is indicated as the purple curve, and in a ganglion cell dendrite (green circle) as the green circle (Yonehara et al., <em>Neuron</em>, 2013).

ERC Starting Grant for research into the brain’s visual processing system

Keisuke Yonehara is leader of the Yonehara Group at DANDRITE (the Danish Research Institute of Translational Neuroscience), Aarhus University. He has just been awarded an ERC Starting Grant of EUR 1.5 million for research into the visual nerve connections that make it possible to see shape and movement.

Making it easier to see the difference between defective and healthy genes in Denmark

It will be easier to diagnose genetically determined diseases in Denmark now that researchers at Aarhus University, the University of Copenhagen and the Technical University of Denmark have mapped the first full individual genomes of 30 out of 150 ordinary Danes. To top it off, they have achieved a very high quality, and thereby reached the first…

In a new study, researchers can reject the fact that finds of molten glass can be used as an argument for a cosmic impact. (Image manipulation with Terragen: Morten Leth Hjuler)

New research casts doubt on the theory of cosmic impact

A new study questions the theory that a cosmic impact caused the extinction of the mammoths and sabre-toothed cats approximately 12,900 years ago. Researchers have studied some of the same layers as proponents of the impact theory from 2006, but can reject the fact that finds of molten glass can be used as an argument for a cosmic impact.

Aarhus University researchers develop modelling tools for Denmark’s new aquatic environment plans

Researchers at DCE – Danish Centre for Environment and Energy – have developed computer models that compare nutrient loading and ecological conditions in Danish fjords and bays. Along with models for open sea areas, these are important tools in Denmark’s forthcoming water management plans 2015–2021. Read more (in Danish only) here.
