Antibiotic treatments can affect the composition of the community of bacteria living in the gut, known as the gut microbiome, for a long time. A new study shows that certain types of antibiotics can be linked to changes in the gut microbiome as long as four to eight years after treatment. The findings have now been published in the scientific journal Nature Medicine.
Researchers have discovered that severe brain tumours in children that appear to be completely different actually arise from the same type of cell. This cell type can give rise to tumours in the pineal gland, the retina and the cerebellum. The discovery that these tumours are related may make it possible to treat them in similar ways.
The climate crisis is not just a physical but also an existential challenge. A new thesis in theology shows how religious faith can complement climate science. While the science often gives rise to climate anxiety, faith offers hope, meaning and motivation for continued action. The study is based on interviews with activists in Sweden and South Africa, from pastors to climate strikers.
People who work at night have a higher risk of coronary artery disease, a type of heart disease. A new study suggests that a higher fibre intake in the diet may help reduce this risk. The study included over 220,000 adults in the UK and is published in the European Journal of Epidemiology.
More cases of colorectal cancer are detected at an early stage with screening. This is according to new research based on data from over 278,000 60-year-olds, who were randomly selected to undergo one of two interventions or no screening at all (usual care). The study, which is a collaboration between Uppsala University and Karolinska Institutet, has been published in Nature Medicine.
In a new study, researchers at Uppsala University have clarified family relationships in four graves from a 5,500-year-old hunter-gatherer culture at Ajvide on Gotland. DNA analyses suggest that the people were well aware of family lineages and that relationships beyond the immediate family played an important role.
Generative AI can help fight misinformation but can also worsen it by creating convincing, hard‑to‑detect manipulations that spread quickly. A new study identifies seven roles AI can play in the information environment and examines their strengths, weaknesses, opportunities and risks.
