Adaptability of trees persists after millions of years of climate change

Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. These are the findings of a study jointly led by Uppsala and Helsinki Universities, published in Nature Communications.

Support for meat rationing to protect climate

Rationing of goods such as meat and fuel can both effectively and fairly reduce consumption with high climate impact. Almost 40 percent of the public say they could accept such measures. These are the findings of new research from the Climate Change Leadership Group at Uppsala University.

Increased access to water a threat to nomadic livestock farmers

Increased access to water a threat to nomadic livestock farmers

Increasing access to water in extremely arid parts of sub-Saharan Africa can help nomadic livestock farmers in the short term. However, in the long run it may lead to serious consequences for their livelihoods. This is shown by new research from Uppsala University, published in Nature Climate Change.

How the major Swedish forest fire of 2014 affected the ecosystem

Swedish researchers from institutions including Uppsala University have spent four years gathering data from the areas affected by the major forest fire of 2014. In their study of how the ecosystem as a whole has been altered, they could see that water quality in watercourses quickly returned to normal, while forested areas continued to lose carbon for many years after the fire.

Genome sequencing paves the way for more sustainable herring fishery

An international team of Swedish, Norwegian, Danish and Irish scientists has used whole genome sequencing to characterise 53 herring populations from the Atlantic Ocean and the Baltic Sea. They have developed genetic markers that make it possible to better monitor herring populations and avoid overfishing. The study is published in the journal eLife.

The genetic basis for timing of reproduction in the Atlantic herring revealed

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

Greenland map facilitates climate research

Greenland map facilitates climate research

For the first time a high-resolution map over the ground below the Greenland ice sheet is available. Researchers at Uppsala University have developed the map that will be of great importance for future possibilities to predict how the Greenland ice sheet melts and moves and that in turn has an impact on rising sea levels as a result of climate change.

​ New, useful feature of Moringa seeds revealed

In a new study, researchers from Uppsala University show that the Moringa seeds can be used for separation of different materials. Separation processes are very important in mining industries and the new knowledge could contribute to reduce the needs for expensive synthetic chemicals.

Zennström climate professorship to Doreen Stabinsky

​Climate researcher Doreen Stabinsky will be Uppsala University’s first holder of the Zennström Visiting Professorship in Climate Change Leadership. She is to take up the position on February 1st and contribute to the establishment of an environment that will be unique, both in Sweden and internationally.

Smart, ecofriendly new battery to solve problems

Present-day lithium batteries are efficient but involve a range of resource and environmental problems. Using materials from alfalfa (lucerne seed) and pine resin and a clever recycling strategy, Uppsala researchers have now come up with a highly interesting alternative. Their study will be presented soon in the scientific journal ChemSusChem.

Surprising findings on hydrogen production in green algae

New research results from Uppsala University instil hope of efficient hydrogen production with green algae being possible in the future, despite the prevailing scepticism based on previous research. The study, which is published today in the esteemed journal PNAS, changes the view on the ability of green algae – which is good news.

Uppsala University - quality, knowledge, and creativity since 1477

Founded in 1477, Uppsala University is the oldest university in Sweden. With more than 50,000 students and 7,500 employees in Uppsala and Visby, we are a broad university with research in social sciences, humanities, technology, natural sciences, medicine and pharmacology. Our mission is to conduct education and research of the highest quality and relevance to society on a long-term basis. Uppsala University is regularly ranked among the world’s top universities.
