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.

Shallow lakes may be a serious source for methane release to the atmosphere. (Photo: Ben Goldsmith).
The annual mean methane emission (divided into diffusion and ebullition) from different experimental treatments within the mesocosm. High and low nutrient levels and then three temperature levels – AMB is ambient temperature, A2 is +2-3ºC and A2+ is +4-5ºC.

Big investment in beer research based on sensors and artificial intelligence

Scientists at iNANO, Aarhus University, are collaborating with Carlsberg, Microsoft and DTU on a research study with the purpose of measuring and sensing flavours and aromas in beer. The project aims at establishing a sensor platform that reduces time and cost to develop new beers with diverse flavours based on the most advanced services and…

WattsUp Power in Hvidovre already produces flywheel systems for energy storage. Using better magnets, they will be able to store energy for much longer periods.

Renewable energy to be stored in floating flywheels

Better magnets can help store renewable energy from solar cells and wind turbines in magnetic flywheels. The new technology for energy storage could help remove one of the really big obstacles to further distribution of renewable energy. Innovation Fund Denmark is investing DKK 12 million in the project.

Danish satellite expertise will revolutionise global mobile coverage

Two companies in North Jutland – 2operate and GomSpace – will work together with Aarhus University to create a new monitoring platform for mega-constellations. Using hundreds of tiny satellites, these can create better signals than the giant satellites of today, and they are both cheaper and more efficient.

Universities invite Danish companies to the top of the world’s materials research

How can small companies each individually use the world’s most powerful neutron and X-ray microscopes for product development? Researchers at Aarhus University (AU), the University of Copenhagen (KU) and the Technical University of Denmark (DTU) will now help them to find the answer – free of charge.

While most people in Denmark take clean drinking water for granted, researchers from institutions including Aarhus University are right now furrowing their brows to find out how we can ensure our groundwater for future generations by preventing contamination from sources such as waste dumps (Photo: Colourbox)

We must ensure clean water for the future

The new GEOCON research project will help save our precious water resources from pollution by developing methods to assess the risk of spreading hazardous substances from contaminated areas to ground and surface water.
