New study demonstrates how high-affinity B cells 'bank' their best traits instead of rolling the dice and risking deleterious mutations, with implications for better vaccine design. A vaccine's ...

Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a ...

Duke researchers find a surprising genetic source of lethal mutations in fruit flies, with possible implications for conservation and health Scientists have puzzled for decades over a basic ...

The sequential accumulation of mutations drives disease evolution from asymptomatic clonal hematopoiesis to frank MDS, and, ultimately, to secondary AML. This detailed understanding of the molecular ...

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

A new estimate of the genetic mutation rate in four wild species of baleen whales suggests that these rates are higher than previous estimates, with some interesting implications for calculations of ...

In the children’s game telephone, a whispered phrase like “I ate a pear” can quickly become “I hate bears” as it moves down a line of players. As genes are passed down from parents to offspring, they ...

A new report found only about 2.8% of people with myelodysplastic syndromes (MDS) have JAK2 mutations. A new report is shining a light on an uncommon—but potentially meaningful—characteristic of some ...

Evolution is perhaps the most extraordinary story ever told—a tale spanning billions of years that connects every living thing on Earth through an intricate ...

A study published in the journal Emerging Infectious Diseases provides a comprehensive overview of the evolution of H3 avian influenza viruses in China. A high prevalence of the H3 subtype avian ...
