There is not one kind of “good sperm” – it depends on other qualities in the male
16 August 2018
In a study published in Behavioral Ecology researchers from Uppsala University show that the same type of sperm is not always the best for all male birds. Depending on how attractive or dominant you are you might be more successful with longer or ...
Magnetic antiparticles offer new horizons for information technologies
15 August 2018
Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. Now, physicists have revealed new behaviour involving the antiparticle equivalent of skyrmions in a ferroma...
The end-Cretaceous extinction unleashed modern shark diversity
3 August 2018
A study that examined the shape of hundreds of fossilized shark teeth suggests that modern shark biodiversity was triggered by the end-Cretaceous mass extinction event, about 66 million years ago.
Eruptive behaviour and magma storage at Bali volcano
16 July 2018
A new study by researchers at Uppsala University and INGV, Italy, published in Scientific Reports, 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 (~...
New research detects brain cell that improves learning
6 July 2018
The workings of memory and learning have yet to be clarified, especially at the neural circuitry level. But researchers at Uppsala University have now, jointly with Brazilian collaborators, discovered a specific brain neuron with a central role in...
Striking differences in brains of wild and domestic rabbits
26 June 2018
An international team of scientists has used high-resolution magnetic resonance imaging (MRI) to study how domestication has affected brain morphology in domestic rabbits. The results show that domestication has had a profound effect on brain morp...

Leading battery researcher Kristina Edström, Professor of Inorganic Chemistry at Uppsala University, has won the KTH Great Prize for 2018. Her research has brought the world closer to a solution to the problem of energy storage. The award citation...
Fatalities in organised violence still decreasing
18 June 2018
New data from the Uppsala Conflict Data Program (UCDP), Uppsala University shows that the number of fatalities in organised violence decreased for the third consecutive year. In 2017, almost 90,000 deaths were recorded by UCDP, a decrease of 32% c...
Endocrine-disrupting pesticides impair frog reproduction
14 June 2018
In a new study, researchers from Sweden and Britain have investigated how the endocrine-disrupting substance linuron affects reproduction in the West African clawed frog. The scientists found that linuron, which is used as a pesticicide, impaired ...
Large-scale whaling in north Scandinavia may date back to 6th century
13 June 2018
The intensive whaling that has pushed many species to the brink of extinction today may be several centuries older than previously assumed. This view is held by archaeologists from Uppsala and York whose findings are presented in the European Jour...
First forecasts from ViEWS – the Violence Early-Warning System
8 June 2018
The challenges of preventing, mitigating, and adapting to large-scale political violence are daunting, particularly when violence escalates where it is not expected. With funding from the ERC, Uppsala researchers have developed ViEWS: a political ...
New doctoral thesis: How over-production of meat is maintained
7 June 2018
Meat consumption is high in Sweden, but production nevertheless outstrips demand. In a new doctoral thesis in sociology, Jonas Bååth has studied how Swedish meat producers are handling the problems that arise when supply of their products exceeds ...
Collaborative project to develop smart electric vehicle charging
5 June 2018
Through the Swedish Electromobility Centre, Uppsala University has entered into a partnership with Vattenfall AB and CEVT (China Euro Vehicle Technology AB) to develop smart EV charging: output that is controlled over time to optimise EV charging ...
Uppsala researchers create world’s fastest water heater
5 June 2018
In an international collaboration, Uppsala researchers have successfully heated water from room temperature to 100,000 degrees Celsius in less than a millionth of a millionth of a second using an X-ray laser that can be regarded as the world’s fas...
Cosmic voids and galaxy clusters could upend Einstein
5 June 2018
New astronomical mappings of hundreds of thousands of cosmic voids and galaxy clusters will make it possible to test Einstein’s theory of relativity by looking for small deviations in gravity at vast distances – a possible explanation for the dark...
New research programme on human evolution
4 June 2018
Since the beginning of February, the University’s research on human evolution has been brought together in a new research programme. The aim is to strengthen the research environment to make it possible to take on larger and more challenging quest...

Virus genes from city pond rescue bacteria
29 May 2018
A key question in evolutionary biology is how new functions arise. New research at Uppsala University shows that bacteriophages (viruses that infect bacteria) can contribute to new functions by revealing hidden potential in their bacterial hosts.
