Zebrafish embryos help prove what happens to nanoparticles in the blood

What happens to the nanoparticles when they are injected into the bloodstream, for example, to destroy solid tumours? With new results published in ACS Nano, researchers from Aarhus University are now ready to tackle such a challenging question using zebrafish embryos as a new study model in nanomedicine and nanotoxicology.

Inauguration of the Danish National Cryo-EM Facility, EMBION

EMBION, Denmark's national cryo-EM facilities, will be inaugurated on 12 October. Cryo-EM (cryogenic electron microscopy) is an important technique in molecular cell biology, medicine and biotechnology. The new research infrastructure's facilities are placed at Aarhus University and University of Copenhagen.

A Danish research team describes in an article in Nature Communications how a well-described circular RNA molecule, which was thought to be carcinogenic, is not found in the cancer cells after all.

Grants for wild ideas

VILLUM Experiment has just awarded grants to a number of researchers, who each represent innovative approaches to their research areas, and who can now test their courageous and strange technical and scientific research ideas. At Aarhus University, nine researchers received a total of DKK 17.8 million.

International initiative seeks to improve healthcare through cell-based medicine

The research initiative LifeTime represents more than 50 European universities, including Aarhus University. A new Perspective article in Nature, co-authored by Jørgen Kjems from iNANO and MBG, outlines LifeTime's vision of how to revolutionize healthcare through personalised, cell-based interceptive medicine.

A European seed dispersal interaction relocated to New Zealand. The Eurasian blackbird (Turdus merula) disperses hawthorn (Crataegus monogyna) seeds. Both species are native to Europe but are pictured here in New Zealand. Photo: Steve Attwood.
Native species disperse the newcomer plants. The kererū (Hemiphaga novaeseelandiae) is the largest seed disperser native to New Zealand, where it disperses European hawthorn (Crataegus monogyna). Photo: Steve Attwood.
Introduced species blur natural geographic signatures in the global network of mutualistic interactions between plants and seed dispersers. Each point represents a plant or animal species and links show interactions observed at any location. Geographic patterns emerge when visualizing only interactions among native species (a) but are blurred when interactions involving introduced species are included (b).
