When did the enamel that covers our teeth evolve? And where in the body did this tissue first appear? In the latest issue of Nature, researchers from Uppsala University in Sweden and the IVPP in Beijing, China arrive at an unexpected answer to this question: enamel originated in the skin and colonized the teeth much later.
A new smart research robot accelerates research on cancer treatments. The new robot system finds optimal treatment combinations. Today Scientific Reports (Nature Publishing Group) is publishing an article about the robot, authored by Dr Mats Gustafsson, Professor of Medical Bioinformatics at Uppsala University.
Children with cancer want honest but hopeful information. But giving appropriate information is difficult and improvements are needed for the sake of the child, the siblings and the parents. In a dissertation from Uppsala University, Li Jalmsell stresses the need for a family perspective and involvement at the end of the child’s life.
For the first time a high-resolution map over the ground below the Greenland ice sheet is available. Researchers at Uppsala University have developed the map that will be of great importance for future possibilities to predict how the Greenland ice sheet melts and moves and that in turn has an impact on rising sea levels as a result of climate change.
A new study shows that variation in genome size may be much more important than previously believed. It is clear that, at least sometimes, a large genome is a good genome. The study is led by Göran Arnqvist, Professor of Animal Ecology at Uppsala University and is published in the scientific journal Proceedings of the Royal Society of London.
An international team led by researchers at Uppsala University reports a surprising discovery from the genomes of eight Iberian Stone-Age farmer remains. The analyses revealed that early Iberian farmers are the closest ancestors to modern-day Basques, in contrast previous hypotheses that linked Basques to earlier pre-farming groups.
New species evolve whenever a lineage splits off into several. Because of this, the kinship between species is often described in terms of a ‘tree of life’, where every branch constitutes a species. Now, researchers at Uppsala University have found that evolution is more complex than this model would have it, and that the tree is actually more akin to a bush.
IgA deficiency is one of the most common genetic immunodeficiency disorders in humans and is associated with an insufficiency or complete absence of the antibody IgA. Researchers from Uppsala University and Karolinska Institutet have now performed the first comparative genetic study of IgA deficiency by using the dog as genetic disease model. The results are published in PLOS ONE.
New research from Uppsala University shows promising progress in the use of anti-inflammatory cytokine for treatment of type 1 diabetes. The study, published in the open access journal Scientific Reports, reveals that administration of interleukin-35 to mice with type 1 diabetes, reverses or cures the disease by maintaining a normal blood glucose level and the immune tolerance.
It is known that sleep facilitates the formation of long-term memory in humans. In a new study, researchers from Uppsala University now show that sleep does not only help form long-term memory but also ensures access to it during times of cognitive stress.
Previous studies have led researchers to believe that individuals with social anxiety disorder/ social phobia have too low levels of the neurotransmitter serotonin. A new study from Uppsala University, however, shows that the situation is exactly the opposite. Individuals with social phobia make too much serotonin. The more serotonin they produce, the more anxious they are in social situations.
New research from Uppsala University shows promising progress in the use of stem cells for treatment of spinal cord injury. The results, which are published in the scientific journal Scientific Reports, show that human stem cells that are transplanted to the injured spinal cord contribute to restoration of some sensory functions.
Researchers from Uppsala University have studied the dynamics of active swarms using computer simulations and experiments on unicellular algae. The team not only found full analogy of the active motion in a field to magnetic hysteresis but also managed to quantify the controllability of the swarm and identify the signatures of collective behavior of the active agents.
In many animal species, the chromosomes differ between the sexes. The male has a Y chromosome. In some animals, however, for example birds, it is the other way round. In birds, the females have their own sex chromosome, the W chromosome. For the first, researchers in Uppsala have mapped the genetic structure and evolution of the W chromosome.
Researchers from Uppsala University have studied the risk of dying over the next five years. They have developed a unique health-risk calculator by using one of the world’s largest study material, UK Biobank, containing data from nearly half a million people. The results are expected to have large areas of application both in the clinical setting, public health policy and in research.
An Uppsala Antibiotics Centre is to be created at Uppsala University. This was announced by Deputy Vice-Chancellor Anders Malmberg at today’s opening of the Uppsala Health Summit conference. The goal is for this interdisciplinary centre to be a regional, national and international knowledge resource and forum in the area of antibiotic resistance.
In a new article published in the Journal of Eurasian Geography and Economics Mikhail Suslov, researcher at Uppsala University, analyzes how the annexation of Crimea in March 2014 has been represented and discussed on Russian-language social networks. The article discusses the paradox of ’digital disempowerment’ but also how no state can control digital irony.
More than 2,000 dissertations from the 17th, 18th and 19th centuries have been digitized and made searchable and readable online. They are accessible as images and full text files in the DiVA system, Uppsala University´s repository for research publications.
Francis Fukuyama, Olivier Nomellini Senior Fellow at the Freeman Spogli Institute for International Studies (FSI) at Stanford University, is awarded the 2015 Johan Skytte Prize in Political Science. He receives it for having with “breath-taking learnedness, clarity and courage thrown new light over the growth of modern political order.”
In a new study, published in Nature this week, a research team led from Uppsala University in Sweden presents the discovery of a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types that comprise plants, fungi, but also animals and humans, evolved from simple microbes.
