Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic double ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases. Later it ...

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and the woman who was left out of the accolades. By Bill Gourgey Published May 31, 2022 7:00 AM EDT Get the Popular Science ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

They were hardly modest, these two brash young scientists who in 1953 declared to patrons of the Eagle Pub in Cambridge, England, that they had "found the secret of life." But James Watson and Francis ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...

His collaboration with biophysicist Francis Crick on the molecular key to all living organisms would make him one of the most ...

James D Watson, co-discoverer of DNA's double-helix structure and Nobel laureate, has died at 97. His groundbreaking work with Francis Crick transformed modern genetics and biotechnology.

James Watson, who co-discovered the structure of DNA has died at age 97. He was a scientific superstar until he made racist remarks that made him an outcast.
