Mary, Mary, quite contrary, how does your crystal grow?

Researchers have managed to create structures that are a complete paradox: single, continuous crystals that have multiple domains, an asymmetric shape and curved lines; they are as complex as one could expect from a 'monumental' structure.

Cartwheeling light reveals new optical phenomenon

Scientists have discovered details about a novel type of polarized light-matter interaction with light that literally turns end over end as it propagates from a source. Their find could help study molecules like those in light-harvesting antennas anticipated to have unique sensitivity to the phenomenon.

The first liquid retina prosthesis

Liquid, biocompatible and micro-injectable, the new retinal prosthesis is an aqueous suspension of photoactive nanoparticles that functionally replace the photoreceptors of the retina damaged by degenerative diseases and aging.

Researchers control elusive spin fluctuations in 2D magnets

Researchers developed a new imaging technique that is fast and sensitive enough to observe these elusive critical fluctuations in two-dimensional magnets. This real-time imaging allows researchers to control the fluctuations and switch magnetism via a 'passive' mechanism that could eventually lead to more energy-efficient magnetic storage devices.

A new theory for semiconductors made of nanocrystals

Scientists have provided the first theoretical explanation for how electrical current is conducted in semiconductors made of nanocrystals. In the future, this could lead to the development of new sensors, lasers or LEDs for TV screens.
