Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

For millennia, evolution has intrigued many great thinkers, prompting questions about how new traits emerge as species adapt over time. Then, attention shifted to natural selection and the inheritance ...

In A Nutshell Ancient origins: Genes linked to dyslexia date back over 430 million years to early vertebrates: they’re not ...

Researchers identified over 400 genes tied to various forms of frailty, offering fresh insight into why people age differently. The study highlights six distinct pathways of unhealthy aging, opening ...

Lurking within the genomes of nearly all species--including plants, fungi, and even humans--are genes that are passed from generation to generation with no clear benefit to the organism. Called ...

In the 1990s, Lee Sweeney, a physiologist at the University of Pennsylvania, demonstrated that inserting the gene encoding insulin-like growth factor 1 (IGF-1) into the muscle cells of mice increased ...

Muscles make up nearly 40% of the human body and power every move we make, from a child's first steps to recovery after injury. For some, however, muscle development goes awry, leading to weakness, ...
