Almost every cell in our body contains around two meters (6.6 feet) of DNA, packed into a tiny nucleus. Yet for the cell to function, this enormous amount of genetic material must remain organized and accessible.

Application of the high-precision technique is part of a clinical trial to treat a genetic disease that can cause liver and nerve damage.

Much remains unknown about the origin of viruses and how they evolve - but hunting for answers has been the focus of Portland State biology professor Ken Stedman's eXtreme Virus Lab for the past 25 years.

Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject their DNA and then use the host's genetic machinery to reproduce. In doing so,

Simulations show that accelerating biochemical reactions could boost DNA-based particle motor speeds beyond 200 nanometers per second, approaching those of natural motor proteins.

Millions of years after an infection, viral DNA still influences how developing chimpanzee brain cells behave.

Researchers have recoveredancient human DNA from cave walls for the first time, showing that genetic material can survive on rock surfaces for thousands of years. The finding grew out of the First Art project,

Japan is witnessing a dramatic transformation in its marine ecosystems as rising ocean temperatures prompt fish species to migrate northward. An extensive research effort involving the analysis of water samples has revealed profound implications for local fisheries,
