Exploring brain synchronization patterns during social interactions

Leave a Comment / News / By

Social interactions synchronize brain activity within individuals and between individuals. In a new study, researchers compared brain synchronization between pairs of people with relatively strong social ties (acquaintance pairs) and pairs with almost no social ties (stranger pairs). The study found that during a cooperative task, the stranger pairs exhibited more closely connected brain networks …

Oxidant pollutant ozone removes mating barriers between fly species

Leave a Comment / News / By

Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to …

A better view with new mid-infrared nanoscopy

Leave a Comment / Technology / By

A team has constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low resolution, especially when compared to other microscopy techniques. This latest development produced images at 120 nanometers, which the researchers say is a thirtyfold improvement on the …

Spintronics: A new path to room temperature swirling spin textures

Leave a Comment / Technology / By

In some materials, spins form complex magnetic structures within the nanometer and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such structures are magnetic bubbles, skyrmions, and magnetic vortices. Spintronics aims to make use of such tiny magnetic structures to store data or perform logic operations with very …

From defects to order: Spontaneously emerging crystal arrangements in perovskite halides

Leave a Comment / Technology / By

A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = formamidinium), they observed that ordered columnar defects appeared in the stacked crystalline layers, taking up one-third of the lattice space. These findings could pave the way to an innovative …
