Three projects focussing on clean water

What impact does the discharge of nutrients have on the pH balance in the sea and on eutrophication? Can more aquatic plants reduce nitrogen and phosphorus in watercourses and provide better water quality? These are just two of the questions Aarhus University will now help to answer with grants from the Velux Foundation totalling DKK 3.9 million.

The pictures show cancer cells that have been exposed to BE-43547 for six hours earlier and have received a green-fluorescent reagent that accumulates and changes the colour to red/yellow in the mitochondria with intact membrane tension. The difference between the two images is that the cells on the left had enough oxygen, while the cells to the right were deprived of oxygen. The lack of red/yellow colour shows that the mitochondrial membranes have been destroyed. The cancer cells are dead. Photo: Thomas B. Poulsen
Each of the two electron-microscope images shows a section of a cancer cell that has been deprived of oxygen for four hours, and a close-up of a mitochondrion in the relevant cell. The cell on the left has been treated with BE-43547, whereas the cell on the right has been treated with an inactive variant of the substance. The difference is clear: the Mitochondrial folded inner membranes (cristae) are intact in the cell to the right, while they have been destroyed in the suicidal cell to the left. Photo: Thomas B.

Natural substance makes cancer cells commit suicide

Researchers at Aarhus University have discovered that a natural substance can kill aggressive cancer cells in a new and effective way. The substance damages the power plants in cancer cells, the mitochondria, and initiates a suicidal process that seems to differ from known forms of programmed cell death, and which depends on the oxygen levels in…

Porpoises are the only whale species that breed in Danish waters. Researchers from Aarhus University have discovered that porpoises use their clicking sounds to find food and to communicate. Photo: Peter Verhoog.

Porpoises communicate in high-frequency Morse code to avoid killer whales

Denmark's only whale, the harbour porpoise, makes use of the same high-frequency Morse-code-like clicking they use to find food to communicate with other porpoises, according to new research from Aarhus University. These new findings provide entirely new insight into the social life of the porpoise.

ERC Starting Grant for research in next level cryptographic protocols

The European Research Council (ERC) has awarded Associate Professor Claudio Orlandi from the Department of Computer Science at Aarhus University a starting grant worth €1.5M for research into private and efficient secure multiparty computation (MPC).

The maps show the diversity of Australian big herbivorous marsupials (a mammalian infraclass) as is today, and as it would be today, had most of the species not been extinct. The phylogenetic tree to the right shows the evolutionary relationships among a sample of extant and extinct species, while the circles illustrate the size of each species as well as their status: EP = Extinct in prehistory, CR = Critically Endangered, NT = Near Threatened, LC = Least Concern.

For the first time, scientists are putting extinct mammals on the map

Researchers from Aarhus University and University of Gothenburg have produced the most comprehensive family tree and atlas of mammals to date, connecting all living and recently extinct mammal species – nearly 6,000 in total – and overturning many previous ideas about global patterns of biodiversity.

Oil rigs may end their days as valuable artificial reefs

A large group of international researchers have just published a scientific article in which they encourage environmental authorities across the globe to rethink the idea of removing oil rigs, wind turbines and other installations in the sea when they are worn out.

Aarhus University selected as the first Danish ‘lighthouse’ research environment in Lund

Denmark has invested billions of DKK in state-of-the-art research facilities around the European Spallation Source (ESS) near Lund in Sweden. Bo Brummerstedt will now be the first research director of a Danish lighthouse environment that will work towards realising the ambitions behind the huge Danish investment. The appointment is accompanied by…

NFRe contributes to nitrogen-fixing symbiotic signalling. In the presence of native soil rhizobia, wild-type plants (WT) are larger, have more shoots (arrow), more flowers and formed pods (arrowhead), while nfre mutant plants are shorter, and have just started to develop flowers, indicating a lower fitness.

New receptor involved in symbiosis between legumes and nitrogen-fixing rhizobia identified

Legumes are able to grow in nitrogen-poor soils due to their ability to engage in symbiosis with nitrogen-fixing bacteria. There is a great interest in using the knowledge about this symbiosis, to enable transfer to other non-symbiotic plants. An international research team has come a step further to understanding this complex biological process.

Encrypted messages in biological processes

RNA modifications can encrypt the RNA code and are responsible for a very sophisticated control of RNA function. A Danish-German research team has shown that modified RNA bases have a great impact on the dynamics of gene expression from DNA to functional RNA. The study yields important new insight into how the basis of RNA modifications can affect…
