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 ...
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 ...
An experimental computer chip called Ice River can reuse the energy put into it, researchers say. A regular computer chip cannot reuse energy. All the electrical energy it draws to perform ...
