The mental symptoms of premenstrual dysphoric disorder improve following treatment with a progesterone receptor modulator, as demonstrated by SciLifeLab researcher Erika Comasco and Professor Inger Sundström-Poromaa, Uppsala University. The mechanism of action of the study drug provides insights into the potential molecular mechanisms underlying this psychiatric disorder and its treatment.
The Indian subcontinent is a hotspot for wild felines. A new study headed by Uppsala University now shows that only 6–11 per cent of the areas where three rare cat species have their habitat are protected. Lack of knowledge about these species has been an obstacle to understanding their needs for reserves. The research is presented in the journal Scientific Reports.
Hydrogen gas and methanol for fuel cells or as raw materials for the chemicals industry, for example, could be produced more sustainably using sunlight, a new Uppsala University study shows. In this study, researchers have developed a new coating material for semiconductors that may create new opportunities to produce fuels in processes that combine direct sunlight with electricity.
A large international consortium led by scientists at Uppsala University and the Broad Institute of MIT and Harvard has sequenced the genome of 130 mammals and analysed the data together with 110 existing genomes to allow scientist to identify which are the important positions in the DNA. The study is published in Nature.
How can stress in animals be measured? Scientists from Uppsala University and elsewhere have now found that what are known as epigenetic biomarkers could be used to detect long-term exposure to stress in commercially raised chickens. This may, in time, lead to improved conditions in animal rearing. The study has been published in the journal Frontiers in Genetics.
The Scandinavian wolf originally came from Finland and Russia, and unlike many other European wolf populations its genetic constitution is virtually free from dog admixture. In addition, individuals have migrated into and out of Scandinavia. These findings have emerged from new research at Uppsala University in which genetic material from more than 200 wolves was analysed.
When and how did the first animals appear? Science has long sought an answer. Uppsala University researchers and colleagues in Denmark have now jointly found, in Greenland, embryo-like microfossils up to 570 million years old, revealing that organisms of this type were dispersed throughout the world. The study is published in Communications Biology.
In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers from Uppsala University can now show, at molecular level, that these changes originate in vein cells. This new knowledge of the condition creates potential for developing better therapies for patients. The study has been published in the journal eLife.
How can new life forms that we cannot see be discovered? Using a novel method based on looking for DNA in soil samples, researchers at Uppsala University have revealed the existence of two hitherto unknown, but very common fungus species. They are thought to perform a key function in the ecosystem, but their exact role remains to be clarified. The study is published in the journal IMA Fungus.
In Alzheimer’s disease, a protein (peptide) forms clumps in the brain and causes sufferers to lose their memory. In a recently published article, a research group at Uppsala University described a new treatment method that increases the body’s own degradation of the building blocks that lead to these protein clumps.
Big tidal ranges some 400 million years ago may have initiated the evolution of bony fish and land vertebrates. This theory is now supported by researchers in the UK and at Uppsala University who, for the first time, have used established mathematical models to simulate tides on Earth during this period. The study has been published in Proceedings of the Royal Society A.
In situ sequencing enables gene activity inside body tissues to be depicted in microscope images. To facilitate interpretation of the vast quantities of information generated, Uppsala University researchers have now developed an entirely new method of image analysis. Based on algorithms used in artificial intelligence, the method was originally devised to enhance understanding of social networks.
