Science and Technology researchers granted DKK 21 million

The Danish National Advanced Technology Foundation has granted DKK 21 million to research projects involving scientists at Science and Technology.

This otolith has been burnt and sectioned, and the rings show that it comes from a six-year-old cod. Biologists at Aarhus University have finally succeeded in developing a method to study the one per cent of the otolith that can tell what the fish has eaten and where. Photo: Peter Grønkjær
The researchers’ next step is to use their method on ocean quahogs. This will enable them to take into account natural changes at the bottom of the food chain and include this in their analyses of proteins in cod otoliths. Jens B. Pedersen moved the mussels shown here from the bottom of the Bay of Aarhus – where they can lie buried in the same place for up to 450 years – to aquariums in the deep basement underneath the Section for Marine Ecology at Aarhus University.

Researchers drill out new knowledge from the ‘philosopher’s stones’ of the sea

Otoliths (bony structures in the inner ear of fish) are one of the sea’s most reliable sources of data and, for almost a century, they have provided knowledge about the age and growth of fish. Researchers are now capable of extracting information that can reveal changes in marine food chains during the course of time.

NGC 6752 is the name of the globular cluster observed by the international team of researchers. It is found in the constellation Pavo (The Peacock) and is one of the brightest of its kind in the night sky. Globular clusters are one of the places where the oldest stars are found, and they are also interesting for scientists because they can contain several generations of stars.

Stellar models given a reprimand

An international team of researchers can now demonstrate that the computer models used until now to explain the life cycle of stars are unlikely to be correct. The key to this discovery is the substance sodium, which can be used to reveal the life story of a star.

The map shows where the researchers will drill. This is the first time deep drillings are taking place in inner Danish waters. The drilling vessel will be visible from the Little Belt coast.
 “Core on deck!” A 9.5-metre-long mud core has just been lifted onto the deck of one of the world’s largest scientific drilling vessels – <em>JOIDES Resolution</em> – and it will soon be cut up and analysed in the laboratories on board. The same procedure will take place many times during the drilling expedition in the Baltic this summer. Photo: William Crawford, IODP/TAMU
Bremen in Germany is one of the three places in the world where researchers store mud cores from their expeditions. Here there are 220,000 tubes with approximately 151 kilometres of seabed mud cores from 86 different expeditions. Cores from the Baltic Sea expedition will also end up here so that research groups all over the world can get access to them. Photo: Copyright: MARUM, University of Bremen

Scientists drill into the world of extremes under the Baltic Sea

For the first time ever, geologists and microbiologists will carry out deep scientific drillings in the dynamic subsurface of the Baltic Sea. The researchers will study signs left in the mud so as to understand the violent climate changes that took place during the last 140,000 years, as well as the life of microorganisms in the depths.

Tricky algorithmic method revealed as blind alley

PhD student Thomas Dueholm Hansen, Department of Computer Science, has demonstrated that a classic programming problem cannot be solved the way it was previously assumed. He has now been awarded one of the Aarhus University Research Foundation’s PhD prizes. Read more (in Danish only) here.

Unknown territories of the body

For about a century, most diabetes type 2 patients have been known to form hormonal lumps in the pancreas. Studying these lumps involves viewing images of the tiniest parts of the body on a nanoscale. Researchers can now zoom in and see what the building blocks of the disease look like. Read more (in Danish only) here.

Students drive 6000 kilometres on one litre of petrol

The newcomers managed to exceed their own expectations in this year’s Shell Eco-marathon. In just six months, they went from a good idea to being able to drive with a petrol-equivalent fuel consumption of several thousand km per litre.

Most stochastic geometry models use point processes as basic building blocks. Illustrated here is a special point process model that has a self-similar property, which means a small random segment is identical to the overall structure. (Graphics: Aarhus University)
In stochastic geometry, the size of a spatial object is estimated by sending random lines into the area containing the object and determining the number of lines that strike the object (shown here as yellow lines). (Image: Aarhus University)
Stereology makes it possible to calculate estimates of the parameters for a spatial structure – such as the volume and surface area – based on observations along lines or on planes via a reference point. At CSGB, research is carried out into local stereological methods to determine volume and surface tensors, which can provide new information about shape and orientation distribution in cell populations.

Mathematics research is a global success

Analytical methods developed by mathematicians at Aarhus University have become standard in microscopy on an international level. The mathematical discipline is called stochastic geometry, and the methods are used for purposes such as analysing advanced image data from biological tissue, with a view to understanding cellular changes in brain…

DKK 160 million for research into highly refined bioproducts

Plant residue can be used for more than fuel – it is possible to use the residue for products such as biologically degradable plastic.

Seaweed cultivation works in Denmark’s Lim Fjord

Time for seaweed. In radiant spring sunshine, students and researchers from Aarhus University’s Department of Bioscience and staff from the Danish Shellfish Centre gathered tons of seaweed from their cultivation lines in the Lim Fjord (Limfjorden).

Bt is a tough bacterium

Researchers at Aarhus University have shown that Bacillus thuringiensis (Bt) is a bacterium that can still be found in the soil thirteen years after being sprayed onto a cabbage field. Read the whole story (in Danish only) in the latest edition of RØMER.

Does antimatter fall to the ground?

Everything around us is made of matter. This is an obvious truth at the same time as being a fact and one of the great mysteries in the world of physics. However, a research group under the leadership of an Aarhus University physicist has now taken the first steps towards gaining specific knowledge about the characteristics of antimatter.

Students design their estimate of the car of the future

Aarhus University students are currently combining their academic expertise with creativity to build an extremely energy-efficient eco car. They have been invited to take part in the international Shell Eco-marathon in Rotterdam, where the aim is to go the furthest on the equivalent of just one litre of petrol.
