Darwin’s finches in the Galápagos archipelago provide an iconic model for the evolution of biodiversity on earth due to natural selection. A team of scientists from Princeton University and Uppsala University now reports that they have observed the origin of a new species. A new lineage was formed by the hybridization of two different species of Darwin’s finches.
Researchers from Uppsala University and others have for the first time determined the full genetic consequences of intense inbreeding in a threatened species. The large-scale genomic study of the Scandinavian wolf population is reported in Nature Ecology & Evolution.
A team of Swedish scientists have used national registries of more than 3.4 million Swedes aged 40 to 80 to study the association between dog ownership and cardiovascular health. Their study shows that dog owners had a lower risk of death due to cardiovascular disease or to other causes during the 12-year follow-up.
The effect of breastfeeding on the risk of developing asthma and allergy has been debated for a long time. In a recent study, Uppsala University researchers show that breastfeeding might in fact increase the risk of developing hay fever and eczema, while not having any clear effect on the risk of asthma. The results have been published in the Journal of Allergy and Clinical Immunology.
The effect of combining clinically used drugs for the treatment of colon cancer can vary widely depending on concentrations, ranging from cases where the drugs counteract each other to cases where they reinforce each other. This is the main conclusion from a cell culture analysis in which collected data were analysed using novel open source software developed by Uppsala researchers.
At the Uppsala Health Summit Tackling Infectious Disease Threats, due to start next week, experts and decision makers from ministries, academia, companies and voluntary organisations are meeting to discuss how jointly to reduce the risk of severe outbreaks.
Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed for depression and anxiety but their superiority over placebo has been questioned, generating considerable debate among researchers and clinicians. In a new study, Uppsala University researchers show that the way in which the treatment is described to the patient can be as important as the treatment itself.
What was previously thought to be typical Viking Age, silver patterns on woven silk bands, could in fact be geometric Kufic characters. As part of an exhibition at the Enköping Museum, ongoing research is presented where a textile archaeological analysis suggests that both Allah and Ali are invoked in the pattern of the bands.
A genomic analysis of ancient human remains from KwaZulu-Natal revealed that southern Africa has an important role to play in writing the history of humankind. A research team from Uppsala University, Sweden, the Universities of Johannesburg and the Witwatersrand, South Africa, presents their results in the September 28th early online issue of Science.
A research group at Uppsala University has found out how CRISPR-Cas9 - also known as ‘molecular scissors’ - can search the genome for a specific DNA sequence. The new research findings show how Cas9 can be improved to make the molecular scissors faster and more reliable. The study is being published in Science.
Previous research has shown that there is a connection between epigenetic changes and some of our common illnesses. But what does this connection mean? A new study shows that external factors, such as lifestyle aspects, often affect both the epigenetic pattern and cause the disease. The results have been published in PLOS Genetics.
A new species of extinct sea monster from the Early Jurassic has been identified by a team of German and Swedish researchers. The fossilized bones were found in a clay pit near the city of Bielefeld in Germany. The findings will be published in the journal Alcheringa.
