Scientists create world's first 'super-twisted' light

(PhysOrg.com) -- The research team at the University of Glasgow twisted the light like a corkscrew by using a polarising filter, before shining it onto a specially shaped piece of gold to create the world's first 'super twisting'.

Turning viruses into molecular Legos

Researchers at the University of California, Berkeley, have turned a benign virus into an engineering tool for assembling structures that mimic collagen, one of the most important structural proteins in nature. The process ...

Helicopter-light-beams: A new tool for quantum optics

A light wave oscillates perpendicular to its propagation direction – that is what students learn in school. However, scientists of the Vienna University of Technology (TU Vienna) now perform atom-physics experiments with ...

Researchers discover sperm move along a 'twisting ribbon'

(Phys.org) —Opening the door to more sophisticated investigation of sperm locomotion and biophysics, researchers from UCLA's Henry Samueli School of Engineering and Applied Science have identified previously unobserved ...

A microlaser emitting helical light

Researchers recently demonstrated the realization of an integrated microlaser based on a novel design that emits light in chiral modes, thus producing corkscrews of light. An object is said to be chiral if it can be distinguished ...

Screw-shaped bird sperm swim faster—but it comes at a cost

A study by Ph.D. student Hanna Nyborg Støstad has investigated the peculiar spiral shape of songbird sperm. Støstad compared sperm cells of 36 bird species including house sparrows and tree swallows, and found that species ...
