How the DNA Computer Program Makes You and Me
Can a set of simple instructions produce complex, three-dimensional living structures?
How Cells Pack Tangled DNA Into Neat Chromosomes
For the first time, researchers see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression.
Genetic Struggles Within Cells May Create New Species
Mitonuclear conflict — a struggle between the genes in a cell’s nucleus and its mitochondria — might sometimes split species in two.
Genetics Spills Secrets From Neanderthals’ Lost History
How many Neanderthals were there? Archaeology and genetics have given very different answers. A new study reconciles them and reveals the lost history of these ancient people — including an early brush with extinction.
Genetic Architects Untwist DNA’s Turns
Researchers have used the gene-editing tool CRISPR to manipulate the way that DNA coils up inside the cell — another step in the quest to understand how the genome’s 3-D structure impacts its function.
How Strange Twists in DNA Orchestrate Life
Coils and twirls in DNA’s double-helix change how the molecule behaves, opening a new role for topology in the study of life.
