A new mathematical model for predicting variations in solar irradiance has been developed at Uppsala University. It may help to promote more efficient use of electricity from solar energy. In tests of various data models, the model proved capable of making highly reliable forecasts, and emerged as the best for this purpose in some respects.
A research team at Uppsala University has resurrected several billion-year-old enzymes and reprogrammed them to catalyse completely different chemical reactions than their modern versions can manage. The method can be used to develop sustainable solutions within biotechnology, such as for enzyme bioreactors or to chemically degrade environmental toxins.
Sustainable energy storage is in great demand. Researchers at Uppsala University have therefore developed an all-organic proton battery that can be charged in a matter of seconds. The battery can be charged and discharged over 500 times without any significant loss of capacity. Their work has been published in the scientific journal Angewandte Chemie.
The European large-scale research initiative BATTERY 2030+ presents the long-term research roadmap that outlines the actions needed to invent the sustainable batteries of the future.
Pool frogs infected with the parasitic chytrid fungus Batrachochytrium dendrobatidis range over shorter distances. This is the conclusion of a study conducted by researchers at Uppsala University and the Swedish University of Agricultural Sciences (SLU), who have investigated how the fungus affects the mobility of the red-listed pool frog along the Uppland coast.
Long-lived mushrooms that grow in ‘fairy rings’ accumulate surprisingly few mutations over time. This finding indicates that their protection against harmful mutations is well developed. The results, to be published in the esteemed journal Current Biology, are interesting in terms of both medicine and evolutionary biology.
Soon we will be able to replace fossil fuels with a carbon-neutral product created from solar energy, carbon dioxide and water. Researchers at Uppsala University have successfully produced microorganisms that can efficiently produce the alcohol butanol using carbon dioxide and solar energy, without needing to use solar cells. The results have been published in Energy & Environmental Science.
A research project led by Uppsala University has been awarded a EUR 3.2 million grant by the European Commission. The aim is to create renewable solar fuel using soap foam, carbon dioxide and sunlight.
High levels of polychlorinated biphenyls (PCBs) in the blood are associated with premature death. This is shown by a cross-disciplinary study, based on 1,000 randomly selected 70-year-olds in Uppsala, that is published in the JAMA Network Open journal today.
In a new scientific article, researchers at Uppsala University describe how, using a completely new method, they have synthesised an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilise the cell’s own energy, and thereby enable hydrogen gas to be produced from solar energy.
A new study by researchers at Uppsala University and INGV, Italy, sheds light on magma storage under the currently active Agung volcano on the island of Bali in Indonesia. Magma at Agung is stored at both mantle (~20 km) and shallow crustal (~5 km) depths, which may be a potential cause for sudden pressure-driven eruptions in this densely populated part of the world.

In an article in the journal Energy and Environmental Science, scientists at Uppsala University present a type of low-cost and environmental-friendly organic polymer nano-material as photocatalysts for hydrogen generation, and propose the working mechanism of the photocatalytic reactive site.
In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced environmental change.
Hydrogen gas has long been proposed as a promising energy carrier for future energy applications, but generating the gas from water has proved inefficient. In an article in the journal Energy and Environmental Science, scientists at Uppsala University now present an alternative, interdisciplinary method based on principles from nature.
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
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).
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.
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.
