In a new study published by Nature, an international team of researchers led by Uppsala University in Sweden proposes a new evolutionary origin for mitochondria – also known as the ‘powerhouses of the cell’. Mitochondria are energy-converting organelles that have played key roles in the emergence of complex cellular life on Earth.
Antibiotic-resistant bacteria are a global and growing problem in health care. To be able to prevent further development of resistance developing, it is important to understand where and how antibiotic resistance in bacteria arises. New research from Uppsala University shows that low concentrations of antibiotics, too, can cause high antibiotic resistance to develop in bacteria.
A handful of tiny teeth have led scientists to identify the most distant ancestor of today’s kangaroos. The fossils were found in the desert heart of Australia, and then hidden away, and almost forgotten in a museum collection for over three decades. The findings are published in the Journal of Vertebrate Paleontology.
Jane Mansbridge, Charles F. Adams Professor in Political Leadership and Democratic Values at Harvard University, is awarded the 2018 Johan Skytte Prize in Political Science. Professor Mansbridge wins the prize for “with sharpness, deep involvement and feminist theory having shaped our understanding of democracy in its direct and representative forms.”
In a new study, published in Current Biology this week, a research team from Uppsala University reports new insights into the regenerative capabilities of Stentor, a single celled model organism for regeneration biology. The study used novel gene expression methods that allowed the researchers to identify over one thousand genes involved in the regeneration process of individual stentor cells.
Dynamic interactions between the nervous system, hormones and the immune system are normally on-going but in diabetes the balance is disturbed. The two studies published in EBioMedicine by an international research team from Uppsala University highlight the importance of the neurotransmitter gamma-aminobutyric acid (GABA) in both Type 1 and Type 2 diabetes.
Viruses have a very limited set of genes and therefore must use the cellular machineries of their hosts for most parts of their growth. A new study, led by scientists at Uppsala University, has discovered a specific host protein that many viruses use for their transport within the cell. The discovery opens up new possibilities to develop a broad spectrum anti-viral therapy.
In a multidisciplinary study published in PNAS, an international team of researchers combined archaeological, genetic and stable isotope data to encapsulate 4000 years of Iberian biomolecular prehistory.
Young digital gamers do not have fewer friends at school than their non-gamer peers, two new research articles from Uppsala University indicate.
The East Asian summer monsoon and desertification in Eurasia is driven by fluctuating Northern Hemisphere ice volume and global sea level during the Ice Age, as shown in a study published in Nature Communications.
Using self-sampling followed by HPV testing, more than twice as many women at risk of developing cervical cancer could be identified and offered preventive treatment. This is shown by researchers at Uppsala University in the first randomised study in the world comparing two ways of identifying cervical cancer, published today in the British Journal of Cancer.
Christina Garsten has been appointed new principal at the Swedish Collegium for Advanced Study (SCAS). She succeeds Björn Wittrock, who was one of the three founding directors of the Collegium. Garsten will take office on 15 August, 2018.
In a new study, researchers from the universities of Uppsala and Lund show why insulin secretion is not working properly in patients suffering from type-2 diabetes. The report is published in the journal Cell Metabolism.
In a new article, published in Nature Materials, researchers from Beijing, Uppsala and Jülich have made significant progress allowing very high resolution magnetic measurements. With their method it is possible to measure magnetism of individual atomic planes.
Researchers at Uppsala University and SLU have found a new way of accelerating wound healing. The technology and the mode of action method published in PNAS involves using lactic acid bacteria as vectors to produce and deliver a human chemokine on site in the wounds.
Warding off the threats of future epidemics will be difficult without better cooperation and contingency plans that allow us to act before a crisis hits. This is one message in a new report summarising the discussions of the Uppsala Health Summit on the theme of Tackling Infectious Disease Threats: Prevent, Detect and Respond with a One Health Approach, which took place in October last year.
Over the last few decades, a wealth of evidence has accumulated to suggest that a lack of sleep is bad for mind and body. Working memory is important for keeping things in mind for briefer periods of time, which thereby facilitates reasoning and planning. A team of sleep scientists from Uppsala University now demonstrates that acute sleep loss impacts working memory differently in women and men.
Why do some Westerners attack Muslim minorities and asylum seekers and why do some Muslims support and engage in terror against the West? New research suggests that the reasons for such extreme behaviour might be the same in both groups. The results have now been published in the European Journal of Social Psychology.
A new study in the Journal of Child Psychology and Psychiatry suggests that infants who pay little attention to synchronous sights and sounds may be at elevated risk of later being diagnosed with autism spectrum disorder (ASD). This knowledge about early development in ASD may contribute to earlier detection and intervention in the future.
When peace researchers at Uppsala Conflict Data Program (UCDP) summarize the conflict situation for the world in 2017, much focus is on the so-called Islamic State, IS. During the year, both Iraq and Syria claimed that IS had been defeated. Does the weakening of IS mean that the trend of large numbers of battle-related deaths in the world is ending?
