In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

A DNA-based computer has solved a logic problem that no person could complete by hand, setting a new milestone for this infant technology that could someday surpass the electronic digital computer in ...

Scientists show how stem cells process DNA with speed and precision, revealing principles that could lead to programmable DNA-based chips for biotechnology and medicine. (Nanowerk News) In the human ...

From the what-could-possibly-go-wrong department: Scientists have now managed to write executable code into DNA that is theoretically capable of infecting the computer that reads it. It was only a ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...
