Electrical cable bacteria were discovered in Aarhus Bay by researchers from Aarhus University, who have described five species of these bacteria so far: three from Aarhus Bay and two from Giber stream. The first species was naturally given the name Electrothrix aarhusiensis. This is a cross section of a cable bacterium with its characteristic ridges containing electrical wires. Photo: Chr.

Electric bacteria in the spotlight

Several years ago, researchers from Aarhus discovered a curious form of electric life on the seafloor. Since then it has become increasingly clear that a significant part of the bacterial world is electrified. Leading researchers from around the world will set this life form in focus at the first-ever electromicrobiology conference, held on March…

The well-preserved corpse of the Skrydstrup woman, who was 17-18 years old when she was buried approximately 3,300 years ago. New strontium analyses from the area around the burial mound show that she probably lived all her short life in the region, and she did not travel to the region from afar, as suggested by previous analyses.

Strontium signatures near the Egtved girl's burial mound. Light blue dots mark water holes where the strontium signature is significantly higher than had previously been reported for Denmark. Dark blue marks water holes where the strontium signature is slightly above previous values. Yellow marks water holes where the strontium signature is within what had previously been reported. In the topographical map, the Vejle river valley is shown clearly in shades of green, while the moorland plain west of the river valley is shown in yellow and orange. The brown bars below the map show the values measured for the Egtved girl and the artefacts she had with her in the grave, while the values from the water holes on the map have been summarised in the green bar.

New research indicates that the Egtved girl and the Skrydstrup woman were Danish

The Egtved girl and Skrydstrup woman were probably born and raised within a few kilometres of the Bronze Age burial mound they were buried in. Previously, strontium analyses have shown that they could not have come from Denmark, but according to researchers from the Department of Geoscience at Aarhus University, these studies failed to take into…

Aarhus University introduces admission requirements for all technical and science degree programmes

The admission requirements will be introduced from summer 2019. This means that young people dreaming of a career within these fields, but who are unsure whether they meet the requirements, should remember to apply via quota 2, which has a deadline for applications on 15 March.
