Maize fields entice geese to winter in Denmark

More and more geese remain in Denmark for the winter. They forage in the growing number of maize fields all over the country. Researchers warn that, in the long term, the many geese may cause problems for agriculture.

How polarisation helps tumour cells metastasise

An international research team identifies single-cell polarity as a feature of circulating tumour cells that helps cells to leave circulation and found metastases. The novel results provide a new potential target in the fight against metastatic cancer.

New European network on DNA-based nanorobotics coordinated by Aarhus University

Marie Skłodowska-Curie program has funded new consortium, headed by professor Kurt Gothelf at the Interdisciplinary Nanoscience Center, with 4 million euro. Through the training of 15 PhD students the aim is to pave the way for the creation of DNA-based robots.

The temperature in North-East Greenland may decrease to -20 oC in May so researchers need to be well-dressed when the laboratory is located on the surface of the sea ice. (Photo: Kasper Hancke)

Sea ice algae bloom in the dark

Researchers from Aarhus University have measured a new world record: Small ice algae on the underside of the Arctic sea ice live and grow at a light level corresponding to only 0.02% of the light at the surface of the ice. Algae are the primary component of the Arctic food web and produce food far earlier in the year than previously thought.

Nicotinamide Riboside – a new promising treatment against Alzheimer’s Disease

By treating different mouse models of Alzheimer’s disease with a precursor of NAD+, which is a central coenzyme in the metabolism of the cell, an international research team might have found a drug that can be used as treatment against Alzheimer’s disease. Treatment of Alzheimer’s disease mice improved their neuronal function, memory and learning…
