The number of infections by the tick-borne TBE virus that are not detected by health services is far higher than previously assumed. This has been shown in a new study of Swedish blood donors from Uppsala University and the University Hospital in Uppsala. The results have been published in the journal Eurosurveillance, which is associated with the EU’s Centre for Disease Prevention and Control.
Over the period 1970–2016, small publishing houses became increasingly important for the publication of literature in translation in Sweden. More than ever, Nobel laureates are being published by relatively small independent publishers. A specialisation in translations often stems from a publisher’s personal interest in a language or geographical area.
About 350 million people across Africa speak one or more of the 500 Bantu languages. New genetic analysis of modern and ancient individuals suggests that these populations probably originated in western Africa and then moved south and east in several waves. The study has been published in the scientific journal Nature.
Whether infants at five months of age look mostly at faces or non-social objects such as cars or mobile phones is largely determined by genes. This has now been demonstrated by researchers at Uppsala University and Karolinska Institutet. The findings suggest that there is a biological basis for how infants create their unique visual experiences and which things they learn most about.
Researchers at Uppsala University have developed an instrument that makes it possible to measure 21 biomarkers for cardiovascular disease simultaneously with great precision by means of a simple blood test. The aim is to use this type of tool to improve the prediction of cardiovascular complications and facilitate more personalised treatment for patients.
Researchers have identified a new neural circuit in the brain which produces a strong sense of discomfort when activated. The discovery also allows them to show for the first time that the subthalamic nucleus, a structure in the brain that controls voluntary movements, may also play a role in the development of depression. The results could lead to better treatments for Parkinson's disease.
Young children are able to talk in detail about their feelings and how things are at home. They are also good at reading their parents and their emotions by describing their behaviours, facial expressions and tone of voice. This has been shown in a new study by Uppsala University, published in the Journal of Child and Family Studies.
The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur – a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs. The study has been published in the journal Scientific Reports.
Women with a high genetic predisposition for blood clots are six times more likely to develop a blood clot during the first two years of using contraceptive pills according to a new study from Uppsala University. The results have been published in the American Journal of Obstetrics and Gynaecology.
Contraceptive pills can reduce the risk of rheumatoid arthritis, while hormone treatment in connection with menopause can increase the risk later in life. In a new study of more than 200,000 women in the UK, researchers at Uppsala University have discovered connections between the use of sex hormones and the risk of developing rheumatoid arthritis.
Survival rates for men with metastatic prostate cancer have increased by an average of six months, something which coincides with the gradual introduction of ‘dual treatment’ since 2016. This is according to a register study of all Swedish men diagnosed between 2008 and 2020. The results are published in the medical journal JAMA Network open.
An international team of researchers has released a study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin’s finches. The study has revealed the genetic basis of adaptation in this iconic group. The results are published in the journal Science
He opened up a completely new field of research by sequencing the genome of our long-extinct relatives. For his scientific accomplishments, Svante Pääbo was awarded the Nobel Prize in Physiology or Medicine in 2022. He has now been named Uppsala University’s Alumnus of the Year 2023.
Mummification of the dead probably was more common in prehistory than previously known. This discovery was made at the hunter-gatherer burial sites in the Sado Valley in Portugal, dating to 8 000 years ago. A new study, headed by archaeologists at Uppsala University and Linnaeus University in Sweden and University of Lisbon in Portugal, presents new evidence for pre-burial treatments such as desi
Hormones released after a brain injury contribute to movement problems on the left and right sides of the body, scientists from Uppsala University and elsewhere can now show in a new study in rats. The results also suggest that hormone-blocking treatments may help counteract these effects, a finding that has implications for treating people with traumatic brain injuries or stroke.
Male seed beetles with genital structures that injure females may have greater reproductive success. As new research from Uppsala University shows, females that mate with such males benefit, in the sense that their offspring are healthier. This new piece of the puzzle will help scientists to understand how complex mating interactions between males and females have developedevolved.
Uppsala University scientists have designed a new mouse model that facilitates study of factors contributing to the progression of human bladder cancer and of immune-system activation when the tumour is growing. Using this model, they have been able to study how proteins change before, while and after a tumour develops in the bladder wall. The study has now been published in PLOS ONE.
A few males are enough to fertilise all the females. The number of males therefore has little bearing on a population’s growth. However, they are important for purging bad mutations from the population. This is shown by a new Uppsala University study providing in-depth knowledge of the possible long-term genetic consequences of sexual selection. The results are published in Evolution Letters.
Indonesia’s volcanoes are among the world’s most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala University and elsewhere have found new clues. They now understand better how the Earth’s mantle is composed in that particular region and how the magma changes before an eruption. The study is published in Nature Communications.
Depressive symptoms are more common in teenage girls than in their male peers. However, boys’ mental health appears to be affected more if they suffer from obesity. Irrespective of gender, bullying is a considerably greater risk factor than overweight for developing depressive symptoms. These conclusions are drawn by researchers at Uppsala University who monitored adolescents in a new study.
