Triboluminescence of metal halide perovskite films

Researchers discovered that MHP films exhibit triboluminescence when scraped with metals like copper, gold, or platinum, due to friction-induced charge transfer. This phenomenon is universally observed across commonly studied MHP films. The enhancement of PL is attributed to the accumulation of positive charges on the perovskite surfac...

Not thinking about anything: Toward a brain signature of mind blanking

Mind blanking is characterized by decreased connectivity between neural networks, disrupted visual information processing, and reduced sensory input. The study's findings suggest that being awake does not necessarily mean being conscious of something, and mind blanking corresponds to a genuine interruption in the stream of thoughts.

Chinese research maps the evolving global burden of infertility

A Chinese-led study maps the evolving global burden of infertility, revealing a sustained increase in global prevalence and years lived with disability among women. The study also finds that later marriage and childbearing contribute to the elevated infertility burden, while sociocultural factors lead to higher detection rates in women.
