Scientists discover new DNA structure that's not a double helix "In a paper published in Nature Chemistry, researchers from Australia describe the first-ever sighting of a DNA component—called the intercalated motif (i-motif)—within living human cells. The shape of the structure has been...

An international group of researchers has discovered a new phenomenon that occurs in identical twins: independent of their identical genes, they share an additional level of molecular similarity that influences their biological characteristics. The researchers propose a mechanism to explain the...

The idea may have sounded ridiculous to many scientists not so long ago. After all, when are born our brain is supposedly a blank slate. DNA only constitutes the body's building blocks, and the principles of Darwinian evolution states that any new mutation arises fortuitously. In contrast...
