On February 28, 1953, two scientists, James Watson and Francis Crick, announced they had figured out the structure of DNA.

Scientists discover hidden DNA scaffolding that forms before genes activate, revealing life’s blueprint is built before it begins.

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

For decades, scientists viewed the genome of a newly fertilized egg as a structural "blank slate"—a disordered tangle of DNA ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

From a young age, Daniel Khosravinia tinkered and built numerous LEGO models, from knights to the Star Wars Death Star. This sparked his interest in how things are built, and when he learned about the ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily.
