Li Zhao explores the unexpected emergence of de novo genes, shedding light on their crucial function in adaptation and ...

How do cells know what they should become as the body develops? Biological development depends crucially on spatial patterns: the lines that eventually give rise to segments, organs, or markings like ...

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 ...

Bioinformaticians have established that the genes in bacterial genomes are arranged in a meaningful order. They describe that the genes are arranged by function: If they become increasingly important ...

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 ...

Three scientists learned they carry genes that dramatically increase their risk for Alzheimer's disease. Now they're working ...

New research is shining a light on one of genetics' enduring puzzles—how the workings of the so-called "selfish gene" could ...

It's a fact of life: Some people age better than others. Some ease into their 90s with mind and body intact, while others battle diabetes, Alzheimer's or mobility issues decades earlier. Some can ...

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 ...
