How host–virus coevolution unmasked from the genomic record
Retroviruses are important pathogens, which have attacked vertebrate hosts for millions of years. Researchers now provide new knowledge about the long-term interactions of retroviruses and their hosts by analyzing endogenous retroviruses (ERVs), r...
Several Uppsala researchers involved in top breakthroughs of 2014
Rosetta’s arrival at the comet 67P/Churyumov–Gerasimenko and the landing of Philae is this year’s greatest scientific achievement, according to journal Science. Also on the list of the top breakthroughs is the discovery of birds’ evolutionary ‘big...
Overview and analysis of ICT research gives fresh perspectives
The effect of Internet on our lives and society is a constant topic of interest for politicians, business leaders, the media and the general public, an interest that has generated a substantial body of research on the use of ICT. In a newly publis...
New method for quickly determining antibiotic resistance
Scientists from Uppsala University, the Science for Life Laboratory (SciLifeLab) in Stockholm and Uppsala University Hospital have developed a new method of rapidly identifying which bacteria are causing an infection and determining whether they a...
Scientists X-ray tiny cell organelles responsible for carbon fixation
An international team of scientists led by Uppsala University has developed a high-throughput method of imaging biological particles using an X-ray laser. The images show projections of the carboxysome particle, a delicate and tiny cell compartmen...
Why glaciers that flow into the ocean are extremely sensitive to climate change
In a new paper published in the journal Nature Geoscience researchers present a new view of iceberg calving that explains the sudden collapse of ice shelves and sudden retreat of tidewater glaciers, observed as the polar region slowly warm.
Vaccine found to suppress tumor growth and spreading
In a new study published in the scientific journal Oncotarget, researchers from Uppsala University show that a therapeutic vaccine directed against tumor vessels can reduce tumor burden and suppress formation of spontaneous lung metastases in a mo...
New classification improves risk prediction in chronic lymphocytic leukemia
If chronic lymphocytic leukemia patients with a good or poor prognosis could be identified already at the time of diagnosis, physicians would have better possibilities to adjust their therapeutic and follow-up strategies. Now researchers at Uppsal...
Increased dosing of malaria drug in children could decrease risk of infection
Piperaquine is a long-acting malaria drug that kills residual parasites and decreases the risk of reinfection. A study led by Uppsala University researcher Martin Bergstrand shows that increasing the dose used in children could potentially decreas...
First Swedish hard-rock diamonds discovered
An Uppsala-led research group has presented the first verified discovery of diamonds in Swedish bedrock. The diamonds are small, but provide important clues to the geological evolution of rocks.
New findings show that different brain tumours have the same origin
Glioma is a common name for serious brain tumours. Different types of glioma are usually diagnosed as separate diseases and have been considered to arise from different cell types in the brain. Now researchers at Uppsala University, together with ...
Self-reported sleep disturbances linked to higher risk for Alzheimer’s in men
In a new study, researchers from Uppsala University demonstrate that elderly men with self-reported sleep disturbances run a higher risk of developing Alzheimer’s disease than men without self-reported sleep disturbances. The results are published...
Brain simulation raises questions
What does it mean to simulate the human brain? Why is it important to do so? And is it even possible to simulate the brain separately from the body it exists in? These questions are discussed in a new paper published in the scientific journal Neur...
Conductive plastics show potential for use in future batteries
Conductive plastics may be possible to use in batteries of the future, instead of the metal oxides used today. In his thesis, PhD student Christoffer Karlsson has studied and tested a few such polymers and shown that they have potential. The 30 Oc...
Nobel Peace Prize 2014 Highly Relevant in Light of Research
The Nobel peace prize this year goes to Kailash Satyarthi and Malala Yousafzay ‘for their struggle against the suppression of children and young people and for the right of all children to education’.
Low concentrations of heavy metals and antibiotics contribute to resistance
New research at Uppsala University shows that plasmids containing genes that confer resistance to antibiotics can be enriched by very low concentrations of antibiotics and heavy metals. These results strengthen the suspicion that the antibiotic re...
Individual metropolises now global political players
By providing the infrastructure that connects global flows and financial systems, major cities have increased their political power alongside the nation-states. In some cases, they are pursuing their own foreign policy in several areas. In her PhD...
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 ...
Lack of sleep increases risk of failure in school
A new Swedish study shows that adolescents who suffer from sleep disturbance or habitual short sleep duration are less likely to succeed academically compared to those who enjoy a good night’s sleep. The results have recently been published in the...
Improved catalysers could reduce nitrogen oxides in diesel exhausts
It is fully doable to reduce environmentally harmful nitrogen oxide emissions from diesel engines by improving the aftertreatment system in catalysers. This is demonstrated in a thesis by Soma Tayamon at Uppsala University.
