The political ramifications of dependence on Russian natural gas are a current, lively topic of debate within the EU. One issue that deserves more attention is whether sufficient gas will even be available for export to the EU. So argues physicist Bengt Söderbergh, whose dissertation provides an assessment of future Norwegian and Russian gas export levels.  He is scheduled to defend his dissertation on 19 February at Uppsala University. According to forecasts by the International...

The putative skull of Saint Bridget (Birgitta) of Sweden that has been kept in a shrine in Vadstena Abbey is probably not authentic. A new study conducted at Uppsala University reveals that the two skulls, believed to be from Saint Bridget and her daughter Catherine (Katarina), is not from maternally related individuals. Furthermore, dating show that the skulls are not from the time period when Bridget and Catherine lived. The findings are published in the journal PLoS ONE. Vadstena parish...

A new study by a research team at Uppsala University shows how new functions can develop in an enzyme. This can explain, for example, how resistance to toxins can occur so simply. The findings are now being published in the Journal of Biological Chemistry. Every biological being needs a large number of enzymes for the many functions of cells. In the spirit of Darwin, enzymes in an organism can change over time to meet new needs. This is done by alterations in the enzymes' building blocks that...

When ribosomes produce protein in all living cells, they do so through a chemical reaction that happens so fast that scientists have been puzzled. Using large quantum mechanical calculations of the reaction center of the ribosome, researchers at Uppsala University in Sweden can now provide the first detailed picture of the reaction. The findings are published in the Web edition of Proceedings of the National Academy of Sciences, PNAS. It was previously known how the chemical reaction goes...

It should be possible to use therapeutic vaccines to create both cheap and effective drugs for diseases like cancer and allergies. One problem in developing such vaccines has previously been the lack of adjuvants, substances that make vaccines more effective. However, there has now been a major breakthrough in this area. The study, led by scientists at Uppsala University, is published in the December issue of the journal Vaccine. Many of the treatment methods that are developed today for...

Researchers at Uppsala University, Swedish University of Agricultural Sciences and Broad Institute have discovered a previously unknown gene ZBED6 that is unique to placental mammals. The gene originates from a so called jumping gene that integrated in the genome of a primitive mammal at least 150 million years ago and has since then evolved an essential function. The study is published in PLoS Biology today. Domestic pigs develop more muscle and store less fat than their wild ancestor, the...

Researchers at Uppsala University and University Children's Hospital in Uppsala have devised powerful new tools for typing cells from children with acute lymphatic leukemia and for prediction of how children with leukemia will respond to chemotherapy. The study was recently published in electronic form by the prestigious hematological journal Blood. Acute leukemia is the most common form of childhood cancer. The new study shows that DNA methylation is a promising tool for predicting disease...

Researchers at Uppsala University, in collaboration with colleagues in Sweden and abroad, have identified an entirely new mechanism by which a specific protein in the body inhibits formation of new blood vessels. Inhibiting the formation of new blood vessels is an important aspect of, for example, cancer treatment. The study is published in the November issue of the journal Molecular Cancer Research. Angiogenesis, the formation of new blood vessels, is strictly regulated by a number of...

Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers from Uppsala University in Sweden have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, opening the door to applications of a number of powerful techniques in plant research. The findings have been published in the distinguished journal Proceedings of the...

Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop. This is shown by a new study by Uppsala University researchers Elena Jazin and Björn Reinius, which has been published in the latest issue of the journal Molecular Psychiatry. Professor Elena Jazin and doctoral student Björn Reinius at the Department of Physiology and Developmental Biology...


Word of the Day
jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
