Overview of some of the RNA origami structures designed in the current study compared with a bacterial ribosome (grey). RNA origami structures are coloured by the elements they consist of: 180 degree interactions (purple), 120 degree interactions (dark green), tetra loops (yellow) and dovetail seams (dark blue). Central structure scaffold aptamers (green and orange) and fluorescent proteins. Figure: Cody Geary and Ebbe S. Andersen.
Design and characterisation of RNA origami structures. RNA drawings, atomic models and sequences are designed on the computer. A DNA template is synthesised and transcribed and then folded by an RNA polymerase. The RNA structure is characterised by microscopy methods. Figure: Cody Geary

Bigger and better RNA scaffolds for organising proteins

Researchers from Aarhus University and Caltech have developed a method to build much larger, though still nanosize, RNA scaffolds than previously thought possible using RNA origami. The method is based on new software that has been made available online so other researchers can use it to develop biosensors, nanorobots and medicine – including…

The endless possibilities of impossible salt

This summer, Aarhus University will welcome Professor Anja-Verena Mudring when she joins the Department of Chemistry. Professor Mudring is one of the world's top researchers in the field of materials research. She is one of the leaders in materials development for energy conversion, and she has made a particularly prominent impression in the field…

Geologist Astrid Strunk receives AUFF's PhD award

Every year, the Aarhus University Research Foundation awards PhD prizes to five young researchers with extraordinary talent. The five award recipients have all made a name for themselves, both with their results and with the way they have communicated the results.

Among other things, the researchers found eDNA from stonefly larvae. The picture shows an adult stage stonefly found in the Store Hansted Å stream. Stoneflies are often found near freshwater streams. They require an aquatic environment with high water quality and are therefore a good indicator of the state of the aquatic environment. Photo: Philip Francis Thomsen, AU

Researchers use DNA from streams for biodiversity monitoring

Why spend time wading through streams and rivers to catch insects and other small animals with finely meshed nets, when all you need is their DNA in a water sample to check the biodiversity in the watercourse? Using this method, which is called environmental DNA (eDNA), researchers from Aarhus University have detected 212 different species of…

New coalition of industry and academia to commercialise solution for full recyclability of wind turbine blades

A new partnership between Skrydstrup Group (iNANO & Dept. of Chemistry, Aarhus University), Vestas, Olin, and the Danish Technological Institute collides industry and research to support circularity of wind turbine blades. The CETEC project paves the way for manufacturing new blades using materials from old turbine blades, thereby creating fully…

Professor Thomas B. Poulsen is heading the work to make toxic growth promoters more useful as antibiotics for humans. Photo: Peter F. Gammelby, AU
The graphs show the ability of three different polyethers to inhibit growth (measured as absorption) of methicillin-resistant staphylococcus aureus (MRSA) as a function of the concentration of the substances. Lasalocid and monensin are two naturally occurring polyethers, and HL201 is a synthetic ionophore produced during the study. The substances have a comparable ability to inhibit the growth of MRSA. MIC = ‘minimal inhibitory concentration’ and it is the absorption at which bacterial growth can no longer be detected with the naked eye.

Unexpected new weapon against resistant bacteria

A research group at Aarhus University has found a way to transform a naturally occurring substance class that is toxic for both bacteria and mammals so that it is only toxic for bacteria, including antibiotic-resistant bacteria. This means that polyether ionophores, as the substances are called, could be candidates for the antibiotics of the…

PhD Alexander Sandahl, together with Professor Kurt Gothelf, Professor Troels Skrydstrup and a number of students in the groups, has developed a method for efficient and automated production of ingredients for DNA synthesis. (Illustration: Colourbox)

New method for producing synthetic DNA

Chemically synthesized short DNA sequences are extremely important ingredients with countless uses in research laboratories, hospitals and in industry, like in the method for identifying COVID-19. Phosporamidites are necessary building blocks in the production of DNA sequences, but they are unstable, and break quickly. PhD Alexander Sandahl…
