Danish researchers have now shown that fish such as cod move around with an internal fitness tracker that continuously logs information about the fish’s metabolism. Information is recorded in the calcium structure in the fish’s otoliths and can be used to gain new knowledge about how changes in the marine environment affect a fish’s metabolism and behavior.

The fish’s fitness tracker. The carbon in fish otoliths comes from two sources, partly from the water in the form of dissolved inorganic carbon (blue bullets) and partly from the food burnt off as part of the fish's metabolism (red bullets). Carbon from the two sources is diffused into the fish’s blood. When the fish’s metabolism increases, the proportion of carbon from the food increases, and there will be more "red bullets” in the blood supplying the carbon to the otoliths in the fish’s inner ear. In this way, the growth rings of the otoliths continuously record record information on the fish’s metabolism in the form of the so-called delta 13C value. Illustration: Ming Tsung-Chung.

Otoliths - the fish’s black box - also keeps an eye on the metabolism

For the first time ever, an international research team has shown that fish otoliths record information on fish metabolism. Analyses of old and new otoliths can therefore provide new knowledge about how different species of fish adapt to new conditions, including climate change.

Over the past couple of years, AU students have helped ready the Delphini - 1 nanosatellite for launch. The satellite is now on board the International space station, from which it will be put into orbit around Earth in February. The aim of the ESA BIC DK is to encourage the students to start their own businesses within space technology after the end of their studies. Photo: Lars Kruse/AU Photo.

On satellite images, researchers can identify the smallest details in specific areas, including the size of the cottages, a decisive indicator of the living standard in the area. The images also reveal how the surrounding areas are exploited – for example for animal grazing, growing of crops or gathering firewood. © Gary Watmough

Satellite images reveal global poverty

How far have we come in achieving the UN’s sustainable development goals that we are committed to nationally and internationally? Yes, it can be difficult to make a global assessment of poverty and poor economic conditions, but with an eye in the sky, researchers are able to give us a very good hint of the living conditions of populations in the…

Aarhus University participates in a new Oresund-Kattegat-Skagerak EU Life Science Network

Gregers Rom Andersen and Poul Nissen from the Department of Molecular Biology and Genetics, Aarhus University, participate in a new three-year EU project for the Oresund-Kattegat-Skagerak (OKS) area, which has received a grant from the EU of EUR 3.6 million.

The cork pops for BERTHA

A newly opened research centre is to investigate how modern life affects our health and illness by bringing together expertise from three out of four faculties. The new centre is called BERTHA, and it was officially opened on Monday 10 December in Roskilde.

A blubber coat and large amounts of fish keep Denmark’s smallest whale, the porpoise, alive in the cold winter

Porpoises are among the world’s smallest marine mammals, but despite their small size they need to maintain a body temperature of 37 degrees year-round, just like all other mammals. We, land-living mammals, would soon succumb to the ice-cold water where the temperature gets down to zero degrees in winter. How do the porpoises meet the challenge?

New centre focusing on life impacts

There is not much knowledge about the effects of environmental and social impacts on health, quality of life and causes of death. A newly established research centre is now working to find out, by applying big data and an interdisciplinary approach to the area.

The ties of blood

The adverse health effects from air pollution, for example, are quite well known. But we do not know how exposure may develop into diseases over the course of a whole life. A new research centre at Aarhus University will attempt to link a unique database with state-of-the art approaches in order to uncover the connection between blood and the…

Rotten gold?

Over the next three years, a project run from Denmark will investigate how to create value based on a foul-smelling nuisance on beaches: rotting seaweed. It turns out that seaweed is home to a small worm which may be of great value for fish farming if the optimal living conditions for the worm can be identified. The project recently received a DKK…

A bigger nose, a bigger bang: size matters for echolocating toothed whales

Whales, dolphins, and porpoises have all evolved to use similar narrow beams of high intensity sound to echolocate prey. Far from being inefficient, this highly focused sense may have helped them succeed as top predators in the world's oceans.

Map of Greenland showing the location of the Hiawatha impact crater in Inglefield Land, along the northwest margin of the Greenland Ice sheet.
Close-up of the northwestern ice-sheet margin in Inglefield Land. The Hiawatha impact crater was discovered beneath the semi-circular ice margin. The structure is also imprinted on the shape of the ice surface, even though it lies nearly 1000 meters below the ice surface. Hiawatha is named after outlet glacier at the edge of the ice sheet. The name was given by Lauge Koch in 1922 during an expedition around northern Greenland, while thinking of the pre-colonial native American leader and co-founder of the Iroquois Confederacy.
