Artificial flowers reveal the pollination habits of insects

Biologists are studying which insects pollinate one of the most widespread plants in the Arctic, thus gaining new insight into the interaction between organisms in the Arctic food web.

Breakthrough in exploration of protein dynamics

Using a uniquely informative technology, a team of Danish researchers has discovered a new type of peptide chain dynamics that controls the stability of the PAI-1 protein. The discovery provides a better basis in the long term for intervening in diseases associated with increased risk of blood clots.

With a new method, researchers use a piece of DNA engineered to bind to metal ions. Using this ‘control stick’, they direct another piece of DNA to a metal binding site on the protein. Illustration: <em>Nature Chemistry</em>

New method provides researchers with efficient tool for tagging proteins

Aarhus University researchers have developed an easier method to create DNA–protein conjugates. The method can potentially strengthen the work involved in diagnosing diseases.

Biologists Jannik Hansen and Jannie Linnebjerg attach small pieces of chicken wire to the Arctic tundra near the Zackenberg Research Station, North-East Greenland. Small fishing line snares are affixed to the chicken wire. Photo: Peter Bondo

Round trip from North-East Greenland to South Africa – a busy bird reveals its route

Researchers have recaptured a long-tailed skua at Zackenberg, North-East Greenland – two years after attaching a light logger to its leg. The small logger contains detailed information about two round trips from northern Greenland to southern Africa.

The focus on educational IT now makes it possible for Science and Technology students at Aarhus University to see video lectures and revise their curriculum whenever and how often they choose. (Illustration: Colourbox)

Video teaching replaces traditional university lectures

Video-recorded teaching is both efficient and extremely popular among students and lecturers, according to a number of pilot projects conducted at Aarhus University. All new students taking the university’s science degree programmes will from now on be offered teaching that has been developed and innovated with a focus on educational IT.

This image from the Hubble Space Telescope (HST) shows the irregular dwarf galaxy UGC 5189A, where the bright supernova SN 2010jl originated. VLT observations of this supernova have shown that these cosmic dust factories make their grains in a two-stage process, starting soon after the explosion and continuing long afterwards. Photo: ESO

Mystery of cosmic dust is solved

The planets of the universe are formed from dust clouds that swirl around newly formed stars and gradually clump together. How the dust grains are formed, however, has long been a mystery. Researchers from Aarhus University and the Niels Bohr Institute at the University of Copenhagen have now shown how supernovae eject dust – and how the dust…

Aarhus University participates in new National Ingredient Centre

The National Ingredient Centre (NIC) is a Danish collaboration between companies, universities and branch organisations in the area of ingredients. The new centre will be officially opened on 17 September 2014 at the Confederation of Danish Industry in Copenhagen.

Playing hide and seek with light

Being able to see light is not enough – it should also be possible to capture it. Peter Balling is a new professor with special responsibilities (MSO) at the Department of Physics and Astronomy, where he will strengthen research into new forms of solar cells.

Social heritage means nothing to engineering students

While social mobility is moving slowly in society, things are really happening in the engineering degree programmes, where one of today’s most striking pattern breaks is in full swing. Read more (in Danish only) here.
