The European Research Council (ERC) has granted an ERC Synergy Grant of 10 million Euros to the project “Recursive and Exact New Quantum Theory” (ReNewQuantum), with Professor Jørgen Ellegaard Andersen as the lead Principal Investigator (PI) with Centre for Quantum Geometry of Moduli spaces (QGM), Aarhus University, as corresponding host…

Using geophysical technology, the project will find a solution for calculating the flow of the cleaning agents below the ground, and the data will then be processed and transformed into a visual 3D model that guides the injection

New innovation project to boost the use of biotechnology for the cleanup of contaminated soil

Ejlskov A / S and Aarhus University work together to develop a faster, cheaper and easier method for cleaning contaminated soil without the need for excavators. Real-time 3D scanning of the subsoil allows biotechnological cleansers to be injected accurately into the contaminated underground, as well as monitoring simultaneously how the cleansers…

The secretive indri (Indri indri) of Madagascar is the largest living lemur. It is also critically endangered and highly evolutionarily distinct with no close relatives, a combination that makes its branch one of most precarious on the mammal evolutionary tree. In the likely event that the indri goes extinct, we will lose 19 million years of unique evolutionary history from the mammal tree of life. Photo:©pierivb, Depositphotos.com

Litopterns, like this Macrauchenia patachonica discovered by Charles Darwin, were a strange looking group of prehistoric South American mammals that were not closely related to any species alive today–they diverged evolutionarily from other mammals over 65 million years ago. When they went extinct at the end of the Ice Age, the mammal Tree of Life lost one of its deepest branches. Illustration:Bruce Horsfall, Macmillan, New York. Via Wikimedia Commons

Mammals cannot evolve fast enough to escape current extinction crisis

We humans are exterminating animal and plant species so quickly that nature's built-in defence mechanism, evolution, cannot keep up. An Aarhus-led research team calculated that if current conservation efforts are not improved, so many mammal species will become extinct during the next five decades that nature will need 3-5 million years to recover.

Climate changes require better adaptation to drought

Europe’s future climate will be characterised by more frequent heat waves and more widespread drought. Heat and drought will both challenge crop production, but drought in particular will be a problem – especially for spring sown crops such as maize.

Can forests save us from climate change?

A new study published in Nature has found that managing Europe’s forests to maximise carbon sequestration has a negligible effect on the global climate.

Goldilocks principle in biology – fine-tuning the ‘just right’ signal load

In the fairy tale "Goldilock and the Three Bears", the girl Goldilock goes to the bears’ house where she finds three bowls of porridge, but only one has the “just right” temperature, and in the same way within biology, you can find the "just right" conditions - called the Goldilocks principle.

Bigger. More. Better.

Professor with special responsibilities Jacob Sherson has a mission; he want to reinvent the way computers and humans interact. He’s reinvented himself a few times along the way, and today he says he’s a sort of version 3.0 of himself. The physicist has now been awarded the 2018 Grundfos Prize of DKK 1 mill. for his work on the interface between…

Sustainability on the curriculum for 370 pupils

Perhaps the Danish high-school students who know most about sustainability. At all events, 370 students from Aarhus Tech now know a little more after hearing about the latest knowledge and technology last Friday at a theme day at Aarhus University.

Honorary doctor at Aarhus University receives Nobel Prize in Chemistry

Sir Gregory Winter has been awarded a quarter of this year’s Nobel Prize in Chemistry for his work on antibodies. He has been working with AU researchers for many years, and in 2015 he was appointed an honorary doctor at Aarhus University, Science and Technology.

Following the path of chemicals through the soil

A new and quick way to predict the transport of chemicals through the soil has been developed by researchers at Aarhus University.

In some areas, killer whales feed primarily on sea mammals and big fish like tuna and sharks and are then threatened by PCBs. In areas where the killer whales primarily feed on small fish like herring, they are less threatened. Photo: Audun Rikardsen – www.audunrikardsen.com

PCB transport in the food chains: When foreign hazardous substances enter the marine environment, they are assimilated into the first link in the food chain, phytoplankton. The phytoplankton is consumed by zooplankton, which in turn is consumed by smaller fish, etc. The chemicals accumulate in each link of the food chain, and this means that killer whales that feed on large animals in contaminated areas may contain concentrations of PCBs so high that the survival of the species is threatened. Killer whales that primarily feed on smaller fish are not threatened in the same way. 
Population development: By collecting data from around the world and loading them into population models, the researchers can see that 10 out of 19 populations of killer whales are affected by high levels of PCBs in their body. PCBs particularly affect the reproduction and immune system of the whales. The situation is worst in the oceans around Brazil and the UK where the model predicts that populations have been cut in half over the first decades since the use of PCBs became widespread. Here, the models predict a high risk that the species will disappear within a 30-40-year period. The line indicates median values, while the shaded field shows the variation.

PCB pollution threatens to wipe out killer whales

More than forty years after the first initiatives were taken to ban the use of PCBs, the chemical pollutants remain a deadly threat to animals at the top of the food chain. A new study, just published in the journal Science, shows that the current concentrations of PCBs can lead to the disappearance of half of the world’s populations of killer…

How leaves talk to roots

New findings show that a micro RNA from the shoot keeps legume roots susceptible to symbiotic infection by downregulating a gene that would otherwise hinder root responses to symbiotic bacteria. These findings help us understand what it takes to make nitrogen-fixing symbiosis efficient, and what we need to do to exploit it agronomically.
