A necklace of fractional vortices

Oct 02, 2015 07:00 BST Chalmers University of Technology Researchers at Chalmers University of Technology have arrived at how what is known as time-reversal symmetry can break in one class of superconducting material. The results have been published in the highly ranked Nature Physics journal, which also put the Chalmers researchers' study on the cover.

Sep 23, 2015 18:00 BST Uppsala University 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.

Sep 14, 2015 09:42 BST Uppsala University 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.

Sep 10, 2015 10:00 BST Uppsala University Future computers will require a magnetic material which can be manipulated ultra-rapidly by breaking the strong magnetic coupling. A study has been published in Nature Communications today in which Swedish and German scientists demonstrate that even the strongest magnetic coupling may be broken within picoseconds (10 raised to -12 s). This will open up an exciting new area of research.

Your stomach bacteria determines which diet is best for weight reduction

Sep 10, 2015 07:00 BST Chalmers University of Technology New research enables "tailored" diet advice – based on our personal gut microbiome – for persons who want to lose weight and reduce the risk of disease. Systems biologists at Chalmers University of Technology have for the first time successfully identified in detail how some of our most common intestinal bacteria interact during metabolism.

Sep 07, 2015 20:00 BST Uppsala University 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.

Nanoparticles – small but unique

Sep 07, 2015 16:00 BST Chalmers University of Technology Scientists at Chalmers University of Technology have developed a new way to study nanoparticles one at a time, and have discovered that individual particles that may seem identical in fact can have very different properties. The results, which may prove to be important when developing new materials or applications such as hydrogen sensors for fuel cell cars, will be published in Nature Materials.

Aug 18, 2015 19:00 BST Uppsala University 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.

Jul 30, 2015 19:00 BST Uppsala University 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.
