Scientists have determined the first 3D structures of intact mammalian genomes from individual cells, showing how the DNA from all the chromosomes intricately folds to fit together inside the cell nuclei.
Researchers have identified the role that a four-stranded version of DNA may play in the role of cancer progression, and suggest that it may be used to develop new targeted cancer therapies.
In the first genome-scale experiment of its kind, researchers have gained new insights into how a mouse embryo first begins to transform from a ball of unfocussed cells into a small, structured entity. Published in Nature, the single-cell genomics study was led by the European Bioinformatics Institute (EMBL-EBI) and the University of Cambridge.
A rare DNA base, previously thought to be a temporary modification, has been shown to be stable in mammalian DNA, suggesting that it plays a key role in cellular function.
An international research project to sequence whole genomes from mountain gorillas has given scientists and conservationists new insight into the impact of population decline on these critically endangered apes. While mountain gorillas are extensively inbred and at risk of extinction, research published today in Science finds more to be optimistic about in their genomes than expected.
Whole genome sequencing of MRSA from a hospital in Asia has demonstrated patterns of transmission in a resource-limited setting, where formal screening procedures are not feasible.
Researchers from the African Genome Variation Project (AGVP) have published the first attempt to comprehensively characterise genetic diversity across Sub-Saharan Africa. The study of the world’s most genetically diverse region will provide an invaluable resource for medical researchers and provides insights into population movements over thousands of years of African history. These findings appear in the journal Nature.
What it lacks in genes, it certainly makes up for in legs: the genome of the humble centipede has been found to have around 15,000 genes – around 7,000 fewer than a human.
Ancient DNA shows earliest European genomes weathered the ice age, and shines new light on Neanderthal interbreeding and a mystery human lineage06 Nov 2014
A genome taken from a 36,000 year old skeleton reveals an early divergence of Eurasians once they had left Africa, and allows scientists to better assess the point at which ‘admixture’ - or interbreeding - between Eurasians and Neanderthals occurred. The latest research also points to a previously unknown population lineage as old as the first population separations since humans dispersed out of Africa.
