Churches are preserved by an antiquarian system that risks killing them instead of keeping them alive. The Swedish State and the Church of Sweden therefore need to define new joint visions and goals to enable the ecclesiastical cultural heritage to be used and developed. This is shown by historian of art Henrik Lindblad in a new doctoral thesis from Uppsala University.

Scientists from Uppsala University have used cryo-electron microscopy to reveal details of the protein synthesis mechanism in the parasite Giardia intestinalis, which causes diarrhoeal disease. The new insights could be valuable for screening specific drugs against Giardia and other protozoan parasites.

For nearly 190 years, scientists have searched for the origins of ancient sea-going reptiles from the Age of Dinosaurs. Now a team of Swedish and Norwegian palaeontologists has discovered remains of the earliest known ichthyosaur or ‘fish-lizard’ on the remote Arctic island of Spitsbergen.

Thanks to a gift from an American donor to Uppsala University, Sweden, research into immune reactions in cases of transplantation, autoimmunity and cancer will receive a major boost. The donation, totalling USD 4.5 million, will increase opportunities to develop new treatment strategies in this vital area over the long term.

Overweight and obesity among four-year-olds increased during the COVID-19 pandemic, according to a new study by Uppsala University involving over 200,000 children in Sweden. The number of children with obesity increased by some 30 percent, and there are large regional differences. The study was published in the journal Acta Paediatrica.

Detailed images of illness, death and cancelled activities; these were some of the common themes of children’s drawings during the COVID-19 pandemic. A new study from Uppsala University, in which researchers studied 91 drawings made by children aged between 4 and 6, shows that the pandemic affected the children significantly and that they had extensive knowledge about the disease.

A research group at Uppsala University has developed a simple and effective artificial blood-brain barrier model that can be used to determine how well antibody-based therapies can enter the brain. Today animal experimentation is the most common method for testing an antibody’s function and the new model could reduce the need for animal testing.

On 23 February the Deputy Secretary-General of the United Nations, Amina J Mohammed, will give the Dag Hammarskjöld lecture in Uppsala. The lecture is open to the public.

The use of broad-spectrum antibiotics increased drastically in intensive care at the beginning of the Covid-19 pandemic. At first, this helped patients avoid urinary tract infections and seemed to prevent the growth of most bacteria. However, it also contributed to a sharp growth in enterococci, an antibiotic-tolerant group of bacteria, which rendered the treatment of urinary tract infections more difficult.

Thanks to a new prognostic method for detecting cancers including cancer of the large intestine, doctors could provide clearer disease prognoses and predict which patients will respond best to immunotherapy. The method consists of a combination of two types of immune cells that characterise certain forms of cancer. This has been shown in a new study by researchers at Uppsala University to be published in the journal eBioMedicine.

The earlier infants begin to taste small samples of solid food, the earlier they eat more food and stop breastfeeding. This is shown in a new study from Uppsala University and Sophiahemmet University, in which the mothers of 1,251 infants from all over Sweden participated. Almost half of the infants received tastings at the age of four months.

Bacterial perseverance is a new phenomenon that helps explain how bacteria adapt to survive antibiotic treatments. A group of researchers at Uppsala University have studied how individual bacteria react when exposed to different antibiotics. The result underlines the importance of adhering strictly to antibiotic prescriptions.

A new study from researchers at Uppsala University presents novel findings on why human lymph nodes lose their function with age and the consequences for the effectiveness of our immune system. The article has been published in The Journal of Pathology.

In a new scientific study, researchers at Uppsala University have shown that Scandinavian wolves carry around 100,000 harmful mutations in their genome. As long as the harmful mutations can be compensated by a healthy genetic variant, this does not need to pose a problem. However, as there has been a high level of inbreeding in the wolf population, the occurrence of double harmful variants has increased with each generation.

Men are at an increased risk of a severe bout of COVID-19 compared to women. Researchers at Uppsala University have now shown that this may be due to loss of the Y chromosome in part of their white blood cells. The findings could eventually be used to assess the risk of developing severe COVID-19 and perhaps to improve treatment.

Using new gene mapping methods, researchers have found connections between atopic dermatitis (eczema) in dogs and several regions of the genome. Some of the genes identified coincide with genes linked to similar problems in humans. The filaggrin gene region, for example, which is regarded as the most powerful risk factor for atopic eczema in humans, has now also been linked to this disease in Labrador retrievers.

Researchers at Uppsala University have discovered and characterised a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.

The European robin’s closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.

Preschool children's play involving tablets is less creative and imaginative compared to their play involving physical toys. This is shown in a new study by Uppsala University, and the difference is substantial. The results counter occasional claims that new technology would make children more creative.

An international team of surgeons and scientists from, among others, Uppsala University has confirmed secure surgical access to the central core of the human cochlea. The research, published today in Scientific Reports, is critical to the first in-human trials of new cell, gene and drug therapies for the inner ear, and will assist with treatment for improving hearing loss and deafness over the long-term.

The malignant brain tumour type medulloblastoma can become resistant to therapy which can cause relapse. Researchers at Uppsala University have discovered a certain protein that makes tumour cells resting and insensitive to radiation treatment. The research group hopes that the results could eventually lead to better treatments for children that have the highest risk to develop relapses.

Food lies at the heart of both health and sustainable development. This year’s Uppsala Health Summit takes on the challenges associated with our food systems and how to make them healthier, more inclusive, equitable and sustainable.

Neurochemical changes in the brain differ among patients with social anxiety treated using both SSRIs and CBT, compared to those treated using only CBT. While the combined treatment involving the medicine blocked the serotonin transporters, availability of such transporters increased in patients who only received CBT.

Vertebrate genomes are repositories for retrovirus code that was deposited into germ line as inherited endogenous retroviruses during evolution. Researchers from Uppsala University and Princeton University now provide new findings about retroviral establishment and distribution among Darwin’s finches. The findings are being published in Nature Communications.

The current nuclear threat is the most serious since the end of the Cold War. How did we get here and what role can the new Alva Myrdal Centre for Nuclear Disarmament play? On 19 October, Uppsala University will inaugurate this highly relevant centre. Speakers at the inauguration include Beatrice Fihn, Executive Director of the International Campaign to Abolish Nuclear Weapons (ICAN), recipient of the Nobel Peace Prize in 2017, and Rupal N. Me...

A new dissertation on surrogacy highlights Thai women's experiences of having acted as surrogate mothers. The dissertation shows the women's vulnerability in a global surrogacy industry, but also provides a more nuanced picture of what makes women seek surrogacy and how they relate to the process.

Using state of the art techniques, researchers from Uppsala University have shown that the metabolism in patients with type 2 diabetes and prediabetes was much more disturbed than previously known, and that it varied between organs and with the severity of the disease. The study, which is a collaboration with Copenhagen University and AstraZeneca, among others, has been published in the journal Cell Reports Medicine.

A new study from Uppsala University shows that using a weighted blanket at bedtime increases melatonin in young adults. This hormone increases in response to darkness, and some evidence suggests that it promotes sleep. The findings are published in the Journal of Sleep Research.

On 1 October this year, it will be 400 years since Johan Skytte founded a professorship in eloquence and political science. His intention was to strengthen the state administration by providing the highly qualified diplomats and civil servants that Sweden needed to maintain its position as a European great power. The Johan Skytte Professorship is the oldest active chair in political science in the world. To mark the 400th anniversary, a lectur...

Researchers from Uppsala University and elsewhere have been studying the effect of rising temperatures on the lifespan of pollinating fig wasps. The findings show that the wasps lived much shorter lives at high temperatures, which would make it difficult for them to travel the long distances between the trees they pollinate.

There are strong links between bacteria living in the gut and the levels of small molecules in the blood known as metabolites. Such is the finding of a new study led by researchers from Uppsala University and Lund University, which is now published in the journal Nature Communications.

In just 30 minutes, their test can determine which antibiotic is required to treat a urinary tract infection. Johan Elf and Özden Baltekin are recognised for their innovation, which will help reduce antibiotic resistance and advance personalised care. 

In a large international study, researchers at Uppsala University have identified DNA regions that are associated with physical activity or leisure screen time. The findings confirm that physical activity is beneficial for health and suggest that a more sedentary lifestyle can be explained by how muscles respond to exercise.

Uppsala University is now handing over the remains of a man contained in the University’s collections to Arjeplog’s Sami association. He will be interred at a ceremony in Arjeplog on 9 September, along with other remains contained in Lund University’s collections.

Since its launch in October last year, the Pregspect website has been used by approximately 18,000 pregnant women. Mikael Elinder, associate professor at the Department of Economics, is one of the researchers behind the service, which calculates personalised birth forecasts.

In the condition known as cerebral cavernoma, lesions arise in a cluster of blood vessels in the brain. In a new study from Uppsala University, researchers show that blood coagulation and blood clot formation are very relevant for the disease and that antithrombotic therapy may be beneficial for cavernoma patients.

Children with cancer can find radiotherapy distressing. A research group at Uppsala University is currently developing a computer game to prepare children for therapy and hopefully make it less scary.

An international team led by Uppsala University researchers has uncovered that eukaryotes (organisms with a cellular nucleus) have made hundreds of big leaps from sea to soil and freshwater habitats, and vice versa, during their evolution. The results, published in Nature Ecology and Evolution, also provide insights into what the habitats of our ancient microbial ancestors looked like.

Researchers from several universities, including Uppsala University, have, by studying helical molecules in the body such as DNA, received clues as to how energy production in fuel cells can be made more efficient without admixture of carbon dioxide and heavy metals. The new research shows how the helical molecules, found naturally in all oxygen-dependent life, catalyses energy production in the cells.

Loss of the Y chromosome in blood cells of men is associated with disease and mortality, but no clear causal relationship has previously been identified. Now, researchers from Uppsala University show in an international study in the journal Science that loss of the Y chromosome in white blood cells causes development of fibrosis in the heart, impaired heart function and death from cardiovascular diseases in men.

In a study, published in Science Advances, an international team of researchers have identified 28 gene regions that have been particularly important in the evolution of Darwin’s finches. These genetic variants do not represent recent mutations but constitute ancestral genetic variation that has accumulated over time as different species of Darwin’s finches have evolved with striking differences in beak morphology.

Violent political protest has become increasingly common across the globe, with the Middle East and Africa displaying the trend most often. This is shown in a new study conducted by peace researchers at Uppsala University. In conjunction with the study, violent political protest has as of now been introduced as its own fourth category in Uppsala University’s conflict database, known as UCDP.

Impaired hearing affects over 1.2 billion people worldwide. But crocodiles, who live almost as long as humans and can surpass 70 years of age, have good hearing throughout their lives. One reason is because crocodiles can create new hair cells, and a research group from Uppsala University is now on the path to finding out why. Hopefully, knowledge from the world of crocodiles will be able to help people with impaired hearing.

Municipalities can use their local housing policy to influence the extent to which refugees are able to settle in the municipality in the long term. While certain municipalities offer refugees permanent housing contracts, others only provide temporary contracts that make it difficult for individuals to stay and establish themselves in the municipality. These are the conclusions of a new study led by the Institute for Housing and Urban Research...

The recent Fagradalsfjall eruption in the southwest of Iceland has enthralled the whole world, including nature lovers and scientists alike. The eruption was especially important as it provided geologists with a unique opportunity to study magmas that were accumulated in a deep crustal magma reservoir but ultimately derived from the Earth’s mantle (below 20 km).

A new study from Uppsala University shows that oral contraceptives and hormone therapy at menopause increase the risk of stroke. The increased risk is greatest during the first year of treatment and then declines. The study, which is now published in Stroke, is based on data from over a quarter of a million women from the UK Biobank database.

New data from the Uppsala Conflict Data Program (UCDP) at Uppsala University show that at least 119,000 people died in organised violence in 2021. This is an increase of 46 per cent compared to the previous year, and the highest number since 2015.

Historic virus infections can be traced in vertebrate genomes. For millions of years, these genomes have been repositories for retroviruses that incorporated their code into germline cells and were inherited as endogenous retroviruses (ERVs). Researchers from Uppsala University now provide new findings about retroviral establishment in the koala genome. The findings are being published in the journal PNAS.

A new study combining archaeological, historical and bioarchaeological data provides new insights into the early Islamic period in modern-day Syria. The research team was planning to focus on a much older time period but came across what they believe to be remains of early Muslims in the Syrian countryside.

Researchers from the Zoonosis Science Center at Uppsala University have identified a new coronavirus. Their study of approximately 260 bank voles caught around Grimsö, Örebro County, shows that the virus is well established in Sweden’s red-backed voles. The finding has been published in the journal Viruses.
