At least 237,000 people died in organised violence in 2022. A new report from UCDP at Uppsala University shows that this is a 97 per cent increase compared with the previous year, and the highest number since 1994. UCDP is the world’s main provider of data on organised violence. Its definition of armed conflict has become the global standard of how conflicts are systematically defined and studied
The use of short flashes of X-ray light brings scientists one big step closer toward developing better catalysts to transform the greenhouse gas methane into a less harmful chemical. The result, published in the journal Science, reveals for the first time how carbon-hydrogen bonds of alkanes break and how the catalyst works in this reaction.
A new study has discovered that the pro-viral host protein ZC3H11A has a critical role to maintain embryo viability during early development. The study has uncovered a previously unknown function of ZC3H11A in the intricate process of embryonic growth and highlights its impact on development. The study is led by Uppsala University and INRAE/Université Paris-Saclay, now published in journal PNAS.
Complicated, hard-to-heal wounds are a growing medical problem and there are currently only two drugs approved with proven efficacy. In a new study on humans, researchers at Uppsala University show that treatment with a specific type of modified lactic acid bacteria works well and has a positive effect on the healing of wounds.
In a new study, researchers at Uppsala University have investigated how junk food affects sleep. Healthy participants consumed an unhealthier as well as a healthier diet in a randomised order. After the unhealthier diet, the quality of the participants’ deep sleep had deteriorated, compared with those who had followed the healthier diet. The results have been published in the journal Obesity.
In a new study, researchers from Uppsala University in Sweden, together with colleagues from the University of São Paulo, Brazil, have investigated the impact that a barren living environment for sows leaves on the next generation. The pigs in the study were bred in Brazil and kept according to breeding standards in that country. The sows’ uncomfortable and unstimulating environment brought with i
The Johan Skytte Foundation is delighted to announce that Alexander Wendt and Martha Finnemore have been jointly awarded the Johan Skytte Prize in Political Science. The prize is a recognition of their exceptional contributions to the field, particularly in advancing the constructivist approach to the study of international relations.
In the quest for fossil-free fuels for aircraft, a new study shows that isoprene could be part of a future solution. Isoprene can be produced by blue-green algae from sunlight, water and ordinary carbon dioxide. The productivity of the cyanobacteria increases if they are exposed to violet light or higher temperatures, and isoprene is ideally suited for photochemical processing into aviation fuels.
Researchers from Uppsala University have developed a method that helps immune cells exit from blood vessels into the tumour and kill cancer cells. The aim is to improve treatment of aggressive brain tumours. The study has been published in the journal Cancer Cell.
Using serial femtosecond crystallography performed with the XFEL technique, scientists have been able to see the crucial final step in the reaction cycle of Photosystem II, and managed to obtain more information on the interaction between Photosystem II and the Mn/Ca cluster. "Such a development is important for scaling up hydrogen production from water by sunlight or renewable electricity."
One strategy that viruses use to take over a host cell is to mimic small parts of the cell's proteins called motifs. In a new study coordinated from Uppsala University, researchers have used a new method and doubled the available information on how viruses mimic human binding motifs. The results suggest new targets for the development of antiviral inhibitors.
A major international research project, jointly led by Prof Kerstin Lindblad-Toh at Uppsala University and Broad Institute has surveyed and analysed the genomes of 240 different mammals. The results, now published in 11 articles in the journal Science, show how the genomes of humans and other mammals have developed over the course of evolution.
