Columbia study reveals bacteria create free-floating genes, challenging genetic code norms

Since the genetic code was first deciphered in the 1960s, our genes seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why changes in a gene's code affect health.

Triploidy causes 42% of early miscarriages in horses

A study of horses – which share many important similarities with humans in their chromosomes and pregnancies – revealed that 42% of miscarriages and spontaneous abortions in the first two months of pregnancy were due to complications from an extra set of chromosomes, a condition called triploidy.

Cellular competition determines X chromosome usage in female bodies

A new study published in Nature Genetics by the Lymphoid Development Group at the MRC Laboratory of Medical Sciences has reveals that the contribution of cells expressing maternal or paternal X chromosomes can be selectively skewed in different parts of the body. The study leverages human data from the 1000 Genomes Project combined with mouse models of human X chromosome-linked DNA sequence variation to advance our fundamental understanding of development in biologically female individuals who have two X chromosomes.

Study identifies genes increasing risk of severe COVID-19

Whether or not a person becomes seriously ill with COVID-19 depends, among other things, on genetic factors. With this in mind, researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with other research teams from Germany, the Netherlands, Spain and Italy, investigated a particularly large group of affected individuals.

Genetic and molecular risk factors discovered for subsequent stroke and MACE

People who experience an arterial ischemic stroke (AIS) or transient ischemic stroke (TIA) are at an increased risk of suffering a second stroke or other major adverse cardiovascular event (MACE), making it critically important to identify risk factors and treatments to prevent these subsequent occurrences.
