Women politicians are significantly more likely than their male colleagues to refrain from speaking out in public for fear of threats or harassment – particularly on issues relating to migration and gender equality. Politicians with an immigrant background are also more likely to avoid making public statements. This is shown by a study based on 43,000 responses from Swedish politicians.
When the Atlantic herring colonised the Baltic Sea thousands of years ago, it needed to adapt to the low salinity. Genes with a vital role in the functioning of sperm, eggs and embryos were crucial to this adaptation. Four specific genes were particularly important, a new study, by researchers from Uppsala University, shows.
Biomarkers in the blood could be used for the early detection of colorectal cancer, lung cancer and ovarian cancer. A new study from Uppsala University shows that the performance of such biomarkers is comparable to or better than established tests and could be developed for clinical use.
Computer simulations can help people gain a better understanding of the situation faced by migrants. This is shown by a new study in which 148 teenagers were assigned random migration pathways, with different start and end points. Along the way, they encountered unforeseen events that affected their journey. Experiences from the game led to a partial shift in attitudes towards migration.
Researchers have identified a previously unknown species of leaf warbler in Japan. Once thought to be a single species, Ijima’s Leaf Warbler, has now been revealed to consist of two: Ijima’s Leaf Warbler and the Tokara Leaf Warbler. It is not their appearance that primarily distinguishes them, but analyses of their DNA and song. The researchers are calling for them to be classified as vulnerable.
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.
