Researchers at Linköping University in Sweden made an unexpected discovery while investigating genetically unique women. Their insights advance our understanding of our most enigmatic chromosome, the ...

When a woman becomes pregnant, the outcome of that pregnancy depends on many things—including a crucial event that happened while she was still growing inside her own mother's womb. It depends on the ...

Systemic lupus erythematosus (SLE), the most common form of lupus, is an autoimmune disorder that occurs more frequently in ...

To Shakespeare's Hamlet, we humans are "the paragon of animals." But recent advances in genetics are suggesting that humans are far from being evolution's greatest achievement. For example, humans ...

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...

A study of artificial human and chimpanzee nerve cells revealed how faster-evolving DNA gives neurons the ability to build increasingly complex brain power How did humans evolve brains capable of ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

A base editor rewrote a single DNA letter while editing human embryos, and every chromosome held even as mosaicism keeps a ...

Learning to read and write is the beginning of literacy, a progression now mirrored in modern genomics. Scientists first read the human genome, a three-billion-letter biological book, in April 2003.

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 ...
