What researchers once thought were knots causing messy electrical signals turn out to be something else entirely: twisted coils called plectonemes,

Scientists are exploring how DNA’s physical structure can store vast amounts of data and encode secure information.

The DNA damage from ionizing radiation (IR) erupting from the Chernobyl nuclear disaster of 1986 is showing up in the children of those originally exposed, researchers have found – the first time such a transgenerational link has been clearly established.
