When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Many of the ancient southern Africans, including those who lived between about 10,200 and 1,400 years ago, "fall outside the ...

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 ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Using comparative molecular biology with human cGAS – which actually inhibits DNA repair – the scientists found that the naked mole-rat's enzyme has four key changes that facilitate the important work ...

Researchers have used a new human reference genome, which includes many duplicated and repeat sequences left out of the original human genome draft, to identify genes that make the human brain ...

Animals that hibernate are incredibly resilient. They can spend months without food or water, muscles refusing to atrophy, body temperature dropping to near freezing as their metabolism and brain ...
