Environmental collapse or sustainable future?
Young people have a bleak view of the future. They believe we are more likely heading towards environmental collapse than towards a sustainable world. A new dissertation from Uppsala University shows that although young people in upper secondary s...
New study reveals how some chickens got striped feathers
Birds show an amazing diversity in plumage colour and patterning. But what are the genetic mechanisms creating such patterns? In a new study published in PLOS Genetics, Swedish and French researchers report that two independent mutations are requi...
Revealed: The genes that affect spawning season in herring
It is very important for all animals to reproduce at the time of year which gives their progeny the best chance of surviving. A new study, which compares DNA from 25 herring populations on both sides of the North Atlantic, reveals a number of gene...
Genes key to killer bee’s success
In a new study, researchers from Uppsala University sequenced the genomes of Africanised 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 rese...
Two new supercomputers strengthen important research
Bianca and Rackham are two new supercomputers that were inaugurated at Uppsala University’s UPPMAX on 24 April. They are both unique in different ways and together they enable new, cutting-edge research in fields such as bioinformatics and materia...
Why do we choose to get vaccinations?
Since vaccines protect not only those who take them, but also the people who otherwise could have been infected, there are many plausible motives for choosing to get vaccinated. Apart from the most obvious – wanting to protect oneself or one’s chi...
New study to resurrect enzymes billions of years old
Members of the international Human Frontier Science Program (HFSP), which seeks to support frontier research in the life sciences, include organisations all over the world. Three-year Program Grants for 2017 have been awarded for a total of 30 pro...
New tool for prognosis and choice of therapy for rheumatoid arthritis
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 ...
B vitamins may reduce negative health effects of air pollution
A new study by researchers at Columbia University’s Mailman School of Public Health and Uppsala University shows that B vitamins might play a critical role in reducing the impact of air pollution on the epigenome, i.e. our cells’ ability to read a...
Measurements by school pupils paved way for key research findings
With their measurements and samples, nearly 3,500 schoolchildren have assisted a research study on lakes and global warming, now published in an academic journal. The results show that water temperatures generally remain low despite the air becomi...
One in five overuses electricity at neighbours’ expense
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), pu...
Time for reflection improves elderly’s mealtime experience
A year of recurrent staff supervision, headed by a dietitian, at nursing homes for the elderly in Sweden resulted in a better mealtime situation for residents. Improvements were observed in how tables were laid and food was served, in sound leve...
Studying genes in clusters allows for better predictions
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...
Archaeologists at the vanguard of environmental and climate research
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 ope...
Rapid increase in resistant intestinal bacteria among preschool children
In a new thesis Johan Kaarme, a paediatrician at Uppsala University Hospital and PhD student at the University, points to a more than sixfold increase – from just under 3% to approximately 20% – in ESBL-forming intestinal bacteria among healthy pr...
Genetic data show mainly men migrated to Europe from the Pontic steppe 5,000 years ago
A new study published in PNAS, 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.
Men with higher cognitive ability better at taking heart medication
After a heart attack, it is important for patients to take medication that lowers cholesterol levels. In a new study published in the European Journal of Preventive Cardiology, researchers at Uppsala and Umeå Universities have found that general c...
New type of nanosensor detects DNA building blocks
Researchers at Uppsala University and in Brazil have developed a new type of nanosensor that can detect single molecules. The nanosensor, comprising a combination of two different materials, has been used to identify the different building blocks ...
Stable solar power requires reliable forecasts
How much sunlight will there be and how much electricity will society need in the next few days? These are questions that need clear answers if solar power is to become a reliable energy source. To solve this problem, researchers at Uppsala Univer...
Organic matter composition found to be critical factor in mercury methylation
The biological formation of neurotoxic methyl mercury is an enigmatic process underpinning mercury-related health and environmental hazards. Nevertheless, the exact mechanisms and the factors controlling the process are still not well understood.
