Scientists are a step closer to understanding how our DNA is squeezed into every cell in the body. They provide the first-ever detailed picture of the nucleosome, the most basic building block of chromosomes (the structures that house our DNA). This finding will inform research on all processes that involve chromosomes, such as gene expression and DNA repair, which are critical to the understanding of diseases such as cancer.
A study of yeast reveals new mechanism that allows cells to adapt to environmental changes more rapidly by accelerating genetic changes around genes that boost fitness.
Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.
Toxins produced by three different species of fungus growing indoors on wallpaper may become aerosolized, and easily inhaled. The findings likely have implications for 'sick building syndrome.
