A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Scientists have uncovered surprising clues hidden deep in human DNA, and the findings are forcing experts to rethink a long-standing theory about our past.

Scientists have long debated how modern humans evolved. For decades, most researchers agreed that Homo sapiens came from one ancestral group in Africa, dating back 200,000 to 300,000 years. But new ...

Humans are closely related to chimpanzees and bonobos, but what are the key factors that make humans genetically different? A new study looks at the process of DNA methylation, in which chemical tags ...

Find out what are the key reasons we need to broaden the sample size of the original map of human DNA created by the Human Genome Project. Clinical drug trials have historically had a much higher rate ...

Researchers have captured the first atomic structures of human SMUG1, an enzyme that helps cells repair damaged DNA. The findings provide new insight into how cells recognize and remove harmful DNA ...
