Supercoiled DNA is far more dynamic than the “Watson-Crick” double helix

Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix. As reported online today in the journal Nature Communications, the simulations also show the dynamic nature of DNA, which constantly wiggles and morphs into different shapes, a far cry from the commonly held idea of a rigid and static double helix. Improving our understanding of what DNA looks like when it is in the...

The Side Slip Seat makes the middle row the best seat on the plane.

The latest innovative concept invented by the Denver based firm Molon Labe Designs is called the Side-Slip seat, and one of the upsides of the design is that passengers “stuck” in the middle row get seats that are two inches wider, 20 inches, versus 18 inches of width apiece for window and aisle seats. The middle seat has long been the scourge of air travelers. While there aren’t really any good seats on a plane, the middle is the choice of last resort. The window seat comes with a view, and ...
