I do not believe in signs (you know like if you see a white pigeon when you leave the house, then your work will be successful or when you see a dead leaf fultterring down then you know that whatever new project you start will be not work etc). If you do believe in signs and you are trying to cross disciplines, then you will love this.

Is this a sign from above that greater interaction between biology and physics will tell us the secret to the life, universe and everything?

What is this wondrous sign? A DNA nebula!

This a actually a nebula that is shaped like DNA. Like some divine Aprils Fool's day joke on physicists.

There is also an explanation for this phenomenon.

Morris hypothesizes that the wave traveling up the magnetic field lines and creating the double helix nebula is a disk of gas at its base, made to spin by the gravity of the black hole at the center of our galaxy. The double strands of the nebula are created by the dumbbell-like structure of the spinning disk, which concentrates the magnetic field lines in two areas, he said—otherwise, the nebula would be cylindrical.

The original article is here and the link is from one of my favourite blogs.
