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.

Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.

Workers installing hammock poles on Michigan State University's campus in August 2023 unexpectedly unearthed the buried stone foundation of an old observatory. Built in 1881 and demolished in the 1920s, the small structure had been covered over for decades. Archaeologists and university staff identified the masonry as part of that 19th-century building, making it a notable historical find on a modern college lawn.

Research compiled by YouGov shows that the COVID-19 pandemic prompted different changes in daily routines around the world. In some places people slept more—Saudi Arabia, Brazil, China and Turkey reported increases—while Australians and Britons admitted to drinking more and residents of Mexico, Brazil and Spain reported cutting back on alcohol. Exercise rose in countries including China, Saudi Arabia, Mexico and the United States, and various nations reported shifts in diet quality.
