Scientists uncover 13 distinct patterns in DNA mutation risks with implications for cancer evolution

Mutations, which occur continuously in every cell of our bodies, are a key contributor to cancer, aging, and neurodegeneration. While exposure to mutagenic chemicals, or mistakes in cellular processes during DNA replication contribute to these mutations, the exact distribution and patterns of these changes across…

Scientists use blood test to track gene expression in the brain

The brain is the most protected organ in the body, sheathed in a complex and nearly impenetrable barrier of specialized blood vessels. While this particular anatomical setup protects it from outside invaders, it also makes it difficult for researchers to study how specific genes are…

Ancient DNA reveals reason for high multiple sclerosis and Alzheimer’s rates in Europe

Researchers have created the world’s largest ancient human gene bank by analyzing the bones and teeth of almost 5,000 humans who lived across western Europe and Asia up to 34,000 years ago. By sequencing ancient human DNA and comparing it to modern-day samples, the international…
