(PhysOrg.com) -- From the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as abundant as they are useful in nature and manufacturing alike. Researchers at the Harvard ...

Optical vortices, a type of structured beam with helical phase wavefronts and ‘doughnut’-shaped intensity distributions, have been used to fabricate chiral structures in metals and spiral patterns in ...

This flower-like image shows a plant that is not developing quite right. It comes from a study in which scientists at EMBL and the University of Sydney unearthed the molecular feedback loop that ...

A study of spiral patterns found in galaxies like our Milky Way could overturn the theory of how the spiral arm features form and evolve. Since 1960s, the most widely accepted explanation has been ...
