German Shepherd dogs bred for working are more curious and less neurotic than German Shepherds bred for show. A new study from Uppsala University and the Swedish University of Agricultural Sciences has shown that the differences are not only apparent in the dogs’ behaviour, but also in their genes. In previous studies, similar genes in humans have been associated with neuroticism.

Even researchers and people with extensive training in statistics often find it difficult to interpret statistical results correctly. This is shown by a new systematic review carried out by Uppsala University and others, in which researchers have analysed 55 studies involving over 15,000 participants.
By combining live imaging of brain tissue with artificial intelligence, researchers at Uppsala University have developed a method that reveals how individual glioblastoma cells spread through the brain, how they can switch between different ways of moving, and how they are affected by cancer treatments. An increased understanding of tumour cell invasion might in the long term contribute to more ef
Premenstrual dysphoric disorder (PMDD) is a common mood disorder associated with the menstrual cycle. A new study published in Nature Communications shows that PMDD does not follow any universal pattern, and that there are three subtypes with different patterns of symptoms. The hope is that this discovery will lead to more individualised treatment.
Premenstrual dysphoric disorder is a more seve
Grades from compulsory school determine which pupils are accepted into popular upper secondary programmes. A new thesis from Uppsala University shows that pupils at for-profit independent schools have, on average, higher grades than would statistically be expected given their backgrounds. The findings suggest that grading is more generous in independent schools and that the differences in grades m
Researchers at Uppsala University have adapted Cell Painting, a widely used imaging method in drug discovery, to look at individual cells inside small 3D clusters of cancer cells. Two drugs that looked almost identical in ordinary flat cell cultures behaved differently in 3D, and the team linked the difference to how each drug switches on the cell’s p53 stress response.
A new model has made it possible to estimate how the backbones of some of the first animals on land could and could not move using sturgeon as a material analogue. These results disprove a long-standing hypothesis that changes in early tetrapod anatomy as they moved onto land gave them improved neck mobility.
