How does a formerly innocuous and obscure virus like Zika transform itself into a feared pathogen inflicting a devastating impact on global health? A new UCLA study suggests that the virus possesses the ability to mutate rapidly, allowing the current outbreak to spread swiftly around the world. The Cell Press journal, Cell Host & Microbe, published the findings today in…
While research has identified hundreds of genes required for normal memory formation, genes that suppress memory are of special interest because they offer insights into how the brain prioritizes and manages all of the information, including memories, that it takes in every day. These genes also provide clues for how scientists might develop new treatments for cognitive disorders such as…
Dr. David Reich from Harvard Medical School and his colleagues have produced a world map of Denisovan and Neanderthal ancestry in 120 diverse populations. Their analysis proposes that Denisovan admixture into humans occurred about 100 generations after Neanderthal admixture. Dr. Reich and co-authors collected their data by comparing known Neanderthal and Denisovan gene sequences across more than 250 genomes from…
Research from Rutgers Cancer Institute of New Jersey examining difficult to treat cancer tumors through genomic profiling shows that tumors with alterations in a signaling pathway responsible for cell regulation may respond to targeted therapy regardless of where the tumor originated in the body. The findings will be presented as part of a poster presentation by members of the Rutgers…
UK scientists have been given the go-ahead by the fertility regulator to genetically modify human embryos. It is the first time a country has considered the DNA-altering technique in embryos and approved it. The research will take place at the Francis Crick Institute in London and aims to provide a deeper understanding of the earliest moments of human life. The…
A group of scientists led by Imperial College London researcher Michael Johnson has identified two ‘gene networks’ associated with human cognitive abilities. “We know that genetics plays a major role in intelligence but until now haven’t known which genes are relevant. This research highlights some of genes involved in human intelligence, and how they interact with each other,” said Dr…
