In a new study, researchers from Uppsala University sequenced the genomes of Africanized bees that have invaded large parts of the world to find out what makes them so extraordinarily successful. One particular region in the genome caught the researchers’ attention and the genes found there could be part of the explanation for the aggressive advances of these hybrid bees.
In a study published today in PNAS, scientists in Sweden and Canada have studied the genetic basis of reproduction in 25 populations of herring from both sides of the North Atlantic. They revealed a number of genes associated with the timing of reproduction, and the genetic variants associated with spring or autumn spawning were found to be largely shared between geographically distant populations
In rheumatoid arthritis, antibodies are formed that affect the inflammation in the joints. In an article published today in the journal Annals of the Rheumatic Diseases, researchers at Uppsala University show that antibodies against the cartilage protein collagen II are associated with a good prognosis.
With their measurements and samples, nearly 3,500 schoolchildren have assisted a research study on lakes and global warming, now published in the journal Scientific Reports. The results show that water temperatures generally remain low despite the air becoming warmer. This helps to curb the emission of greenhouse gases.
Household electricity use falls by more than 30% when residents are obliged to pay for their own personal consumption. This is shown in a new study by researchers at Uppsala University’s and the Research Institute of Industrial Economics (IFN), published in the Proceedings of the National Academy of Sciences of the USA (PNAS).
When many genes regulate a single trait, they commonly work together in large clusters or ‘networks’. Taking this into account allows better predictions of how an individual’s genetic make-up affects the trait concerned. The risk of perceiving the importance of an individual gene incorrectly is also reduced.
The history of people and landscapes, whether natural or cultural, is fundamentally connected. Answering key historical questions about this relation will allow us to approach our most important environmental issues in novel ways. Today in the open access journal PLOS ONE archeologists present a list of 50 priority issues for historical ecology.
A new study, looking at the sex-specifically inherited X chromosome of prehistoric human remains, shows that hardly any women took part in the extensive migration from the Pontic-Caspian Steppe approximately 5,000 years ago. The great migration that brought farming practices to Europe 4,000 years earlier, on the other hand, consisted of both women and men.
In a collaborative effort, researchers at Uppsala and Umeå University now show that the formation of methylmercury in sediment is controlled by the molecular composition of the organic matter. The study has been published in Nature Communications.
Researchers have now found an explanation for what triggered the largest volcanic eruption witnessed by humankind. The volcano’s secret was revealed by geochemical clues hidden inside volcanic quartz crystals.
Patients with glioblastoma have very poor prognosis since there are no effective therapies. In a study published in Cell Reports, researchers at Uppsala University have discovered a correlation between the cell type from which the tumour originates and the growth and drug sensitivity of the tumour.
In a new study, researchers at Uppsala University have found evidence of that climate change upends selection of face characteristics in the collared flycatcher. During the study the annual fitness selection on forehead patch size switched from positive to negative, a reversal that is accounted for by rising spring temperatures at the breeding site.
