Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals.

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

We are exposed to ionizing radiation more often than we think: when we bathe in the sun, which emits UV rays, or when we get X-rayed. Even when we are travelling on an intercontinental flight, which ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation is the first step in DNA replication. This breakthrough, published in Nature ...

In a groundbreaking study, scientists have discovered a way to manipulate the very fabric of life by using light to reshape DNA strands. This innovative approach provides new insights into the ...

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 ...
