On Monday, a paper announcing that all four DNA bases had been found on an asteroid sparked a lot of headlines. But many of ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

JAXA samples reveal that asteroid Ryugu has a complete set of nucleobases, the building blocks of DNA, suggesting these ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the ...

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself. A ...

DNA is the blueprint for life, influencing everything about us—including our health. We know that our genes, the genetic “words” that encode proteins, play a major role in health and disease. But the ...

In a first, scientists have extracted DNA from a Renaissance-era drawing attributed to Leonardo da Vinci, but they can't be sure that the genetic material belongs to the Italian polymath. When you ...

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, ...

The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...

Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...

For years, Customs and Border Protection agents have been quietly harvesting DNA from American citizens, including minors, and funneling the samples into an FBI crime database, government data shows.

The Age of AI will rely on massive volumes of data that can be easily stored and retrieved—and bioscience may have an ingenious solution. A scientist examines a DNA (deoxyribonucleic acid) profile on ...
