Researchers reviewing clinical trials have found little evidence that blue‑light filtering glasses provide the sleep or short‑term eye‑comfort benefits often claimed by makers and some retailers. The review pooled data from 17 randomized trials and reported no consistent short‑term reduction in visual fatigue from computer use, and it could not show clear benefits for sleep quality, vision performance, or long‑term retinal health.

A recent poll of 2,000 British adults found many people follow celebrity news more closely than the lives of family and friends. Forty-four percent said they cared about trivial celebrity matters, and 80% admitted they knew more about celebrities than their own parents. Nearly half reported knowing more about famous people than about their friends. Sixty-one percent believe the media spends too much time on celebrity coverage.

China's Chang'e-4 lander touched down on the Moon's far side in January 2019. Using instruments including ground-penetrating radar, the mission collected subsurface profiles near its landing site. A team writing in the Journal of Geophysical Research: Planets reports the top roughly 130 feet (about 40 metres) of the surface is layered—alternating dust, soil and broken rock—and that a buried impact crater lies within those layers.

During the 2020 lockdown, researchers at the University of East Anglia studied 463 infants aged about eight months to three years to examine nap habits and learning. They tested vocabulary and other cognitive measures and tracked how often and how long children slept. The study found that some children consolidated information during sleep and therefore napped less often, while others who had smaller vocabularies napped more frequently and for longer periods.
