In 2020, an interesting new phenomenon called cosmic birefringence was reported from the cosmic microwave background (CMB) polarization data. Polarization describes light waves oscillating ...

With this method, doctors around the world can easily, rapidly and reliably detect malaria, Ebola or HIV to name only a few. Nothing could be simpler: a drop of blood is placed on a special carrier ...

This diagram represents the the light of a neutron star passing through an area of space where vacuum birefringence, a theory of quantum electrodynamics, is occurring. The light\'s magnetic and ...

Until recently, techniques for measuring birefringence have hardly altered with observations being made using standard polarising microscopes with white light and crossed polars, which can lead to ...

Multiple independent analyses of the oldest light in the universe now point to a subtle but persistent twist in its polarization, a signal that, if confirmed, cannot be explained by the Standard Model ...

Stimuli-sensitive materials can respond to physical forces with structural phase transitions. This also applies to biopolymer-surfactant mixtures, a study by German and Chinese scientists now reports.

A team of researchers led by Assistant Professor Yuki Arakawa, Toyohashi University of Technology, has successfully liquid crystallized π-conjugated 2 rod-like molecules with alkylthio groups ...

This news release is available in German. Nothing could be simpler: a drop of blood is placed on a special carrier substance; after a wait of a few minutes, the slide is placed on a device that emits ...
