Researchers from Cambridge, UK, and Germany have reconstructed the early “evolutionary paths” of COVID-19 in humans – as infection spread from Wuhan out to Europe and North America – using genetic network techniques.
The causes of 40 percent of all cases of certain medulloblastoma – dangerous brain tumors affecting children – are hereditary. A genetic defect that occurs in 15 percent of these children plays a key role by destabilizing the production and breakdown of proteins. The researchers suspect that protein metabolism defects could be a previously underestimated cause of other types of cancer.

Radiology, pathology, medical genetics and laboratory medicine under one roof: many hospitals are toying with the idea of ‘integrated diagnostics’ but it was the medical management at Geneva’s University Hospital that dared to take the first step and consolidate all these diagnostic disciplines in a single organisational unit: The Diagnostic Department. ‘Our long-term vision is a…
Scientists at the University of Bologna have conducted the largest analysis of coronavirus 2019-nCoV genomes sequenced so far. This analysis confirms that the virus originates in bats and shows a low variability: the virus heterogeneity is low. At the same time, researchers identified a hyper-variable genomic hotspot in the proteins of the virus responsible for the existence of two virus…
The situation is extraordinary: there have only ever been four declarations of public health emergencies of international concern in the past and now there are two at the same time. Whilst the risks associated with the novel coronavirus are still unclear, people in the Democratic Republic of the Congo are still battling with an outbreak of the deadly Ebola virus which has been ongoing since 2018…
Within the framework of an international study, Lund University and Skåne University Hospital have started treating patients with hemophilia with gene therapy, something that began in January this year.
