The night smoulders on lava planet

A physics student’s Bachelor’s project has provided deep insight into a planetary system and revealed a surprise about a planet that researchers thought they ‘knew’. An article based on the project has just been published in The Astrophysical Journal. Read more (in Danish only) here.

Talented researcher awarded 40 million core hours on French supercomputer

Postdoctoral Fellow Thomas Kjærgaard has just been allocated 40 million core hours, worth approximately DKK 10 million, on CURIE – the French supercomputer. Next month, the young grantee will start using the large calculator to work on proteins called neurotransmitter transporters.

Dental plaque from 1000-year-old monks reveals serious diseases

Dental plaque (tartar) preserves bacteria and viruses for millennia. A new international study shows that old teeth conceal considerable information about diseases of the past. The study has just been published in Nature Genetics.

Spider silk is acid

In collaboration with an international team of researchers, Professor Daniel Otzen, iNANO and MBG, has come closer to the ‘recipe’ for spider silk. The liquid protein material in the abdomen of the spider gradually becomes more and more acidic as it approaches the spinnerets.

A ton of French fries provides new knowledge

Engineering students at Aarhus University are responsible for one of the most detailed laboratory studies of what happens when French fries are deep fried. They spent twenty days using deep fryers to study changes to the cooking oil over a period of time.

For the last twenty years, astronomers have been searching for exoplanets – without yet finding an ‘Earth 2’. The main objective of the new PLATO space mission is to find ‘Earth 2’. (illustration: NASA)

New space mission to search for ‘Earth 2’

The European Space Agency (ESA) has just decided to build the PLATO satellite, which is planned for launch in 2024. PLATO will begin a detailed search for planets orbiting alien stars. The aim is to find planets that resemble our own Earth. Aarhus University researchers – the only participants from Denmark – will play an active role in the PLATO…

With the acidification expected in Arctic waters due to the increased concentration of CO<sub>2</sub>, populations of sea butterflies and other marine calcifying organisms can be severely threatened due to hampering of the calcification processes.

Arctic biodiversity under serious threat from climate change

Climate change caused by human activities is by far the worst threat to biodiversity in the Arctic. Some of these changes are already visible, according to a new report prepared by 253 scientists led by Dr Hans Meltofte of Aarhus University.

Everyone can catch sight of attractive and conspicuous butterfly orchids. But how many thousands of other species can actually be found in the pastures? The new Biowide research project will find out – a major biodiversity project funded by the Villum Foundation. Photo: Morten D.D. Hansen

Census of life in Denmark

Purse-web spiders, red helleborine, alcon blue butterflies and comb tooth mushrooms. The Danish countryside contains numerous rare and fascinating species – and we know where to find them. Apart from the most charismatic and eye-catching species, however, our knowledge is virtually zero, but a major new research project is about to put an end to…

Origami at the molecular level

Protein clumping in the brain can lead to debilitating diseases such as Alzheimer’s and Parkinson’s. If these processes could be understood and controlled, it would hopefully be possible to develop an effective cure within a few years. Professor Daniel Otzen has been awarded an EliteForsk Award for his contribution to the understanding of protein…

Coexistence between humans and biodiversity – an ecological challenge

What links the global density of trees with conditions such as changes to population density and type of government – i.e. human impact on vegetation? And how has the distribution of flora and fauna changed as a result of climate change? Research into these important questions has contributed to Professor Jens-Christian Svenning, Department of…

New professor will strengthen molecular microbial ecology

Associate Professor Lars Hestbjerg Hansen has been appointed Professor of Molecular Microbiology at Aarhus University’s Department of Environmental Science in Roskilde. The professorship was established to strengthen molecular biology research into the outer environment based on DNA analysis. It will also form the basis for establishing a new…

Researchers are working on a new method to produce bones, cartilage and joints that can cure or alleviate tissue injuries. The idea is to print 3D implants to stimulate the growth of different types of cells in the body. The initial results are promising and the researchers expect the technology to be ready for surgical treatment within the next three years. Research Director Jens Vinge Nygaard, Department of Engineering, is shown here with a section of cartilage implant straight out of the printer. (Photo: Lise Balsby)

Researchers print spare parts for the body

Age-related damage to the musculoskeletal system is the fastest-growing health problem for the European population. Doctors have limited options for providing pain relief, but researchers are now working on a new treatment method that is attracting attention around the world. It involves printing surgical implants and using stem cells to create…
