For many years, researchers believed that the DNA inside a newly fertilized egg began as a structural ‘blank slate’ – a loose ...

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 ...

Authorities confirm the DNA belongs to Nancy Guthrie, 84, who was last seen on Jan. 31 at her home in Arizona A sheriff in Arizona tells PEOPLE that investigators discovered "biological DNA" evidence ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

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, ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

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 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. The cassette tape. A staple of the Walkmans, car stereos, and ...

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 ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

Lily Wood is forty-three years old but considers April 9, 2019, to be her “rebirth day.” That was the date she received her results from Ancestry, the direct-to-consumer DNA-testing company. A ...
