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

Infertility affects millions of individuals worldwide and is often caused by the absence of functional gametes. In women, age-related decline in oocyte quality and quantity has been recognized as a ...

How did humans evolve brains capable of complex language, civilization, and more? The answer could lie in exceptional DNA. Scientists at UC San Francisco have found that parts of our chromosomes have ...

(Cavan Images/Getty Images) The human Y chromosome is shrinking. In the next 5 million years or so, some geneticists think the sex-determining chromosome will vanish completely from our species. In ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Recent technological advances have facilitated the assembly of telomere-to-telomere (T2T) genomes. The current T2T CHM13 showcases the complete architecture of the human genome, yet its use in ...

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.

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells. Researchers at RPTU have now investigated the detailed effects of such imbalances ...

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 ...
