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.

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their ...

Researchers use DNA nanotechnology to build layered lattice structures that produce new interference patterns with unique physical properties and nanoscale control. (Nanowerk News) Researchers are ...

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists from the German Cancer Research Center (DKFZ) and the Universities of Cambridge and ...

We and our colleagues have developed a way to store data using pegs and pegboards made out of DNA and retrieving the data with a microscope—a molecular version of the Lite-Brite toy. Our prototype ...

Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

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 ...

Using a computer-like system made from engineered DNA, scientists have computed the square root of 900. Biologists have proposed using genetic material for performing computations since as early as ...
