In a major international study, the pig genome is now mapped. Researchers from Uppsala University and the Swedish University of Agricultural Sciences (SLU) have contributed to the study by analysing genes that played a key role in the evolution of the domesticated pig and by mapping endogenous retroviruses (ERV), retroviruses whose genes have become part of the host organism’s genome.
What role do new media play in creating the content of the concept of a nation? Today there’s a great deal of interest in marketing the distinctive character of countries as brands in a global market. The sociologist Magdalena Kania-Lundholm shows that new media can be a positive democratic force when countries undergoing dramatic change seek a new national identity.
When a female mates with several males, these will compete over the fertilization her eggs. This is an important evolutionary force that has led to the evolution of a diversity of male sexual organ morphologies. This is revealed in a study of seed beetles published today in the leading scientific journal Current Biology.
In an article in the leading scientific journal Nature, researchers at Uppsala University in Sweden describe how they mapped the genomes of the European pied flycatcher and the collared flycatcher and found that it is disparate chromosome structures rather than separate adaptations in individual genes that underlies the separation of the species.
A type of haemorrhagic fever (Crimean-Congo) that is prevalent in Africa, Asia, and the Balkans has begun to spread to new areas in southern Europe. Now Swedish researchers have shown that migratory birds carrying ticks are the possible source of contagion. The discovery is being published in the US Centers for Disease Control and Prevention journal Emerging Infectious Diseases.
How new genes arise poses a fundamental biological question. New findings by researchers at Uppsala University and in the US show that it is possible to get new genes to develop in a laboratory environment using a rapid, stepwise process where an already existing gene with multiple functions is initially amplified.
Researchers at Uppsala University have, together with Brazilian collaborators, discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can explain our ability to remember and sort information.
Astronomers at Uppsala University in Sweden will receive a grant of more than SEK 23 million from the Knut and Alice Wallenberg Foundation to search and analyse atmospheres surrounding earth-like exoplanets. Ultimately these researchers hope to find traces of life on these planets.
It was long believed that proteins need to be well structured to function, but during the last decade it has become clear that disorder is often crucial for function. Now, a research team at Uppsala University has shed light on how such disordered proteins interact with each other.
The Khoe and San peoples in southern Africa play an important role for our understanding of the evolutionary history of humans. These peoples are directly descended from the first branching of the genealogical tree for today’s humans. This is shown in a study led by Uppsala University and being presented in the Web version of the journal Science today.
Newly formed emotional memories can be erased from the human brain. This is shown by researchers from Uppsala University in a new study now being published by the academic journal Science. The findings may represent a breakthrough in research on memory and fear.
The potential value of biobank research is immense. But why should you contribute? In a doctoral thesis from Uppsala University, Joanna Stjernschantz Forsberg claims that we have a moral duty to take part in biobank research.
