Columbia Engineering researchers developed a porous polymer coating that can cool surfaces below the surrounding air temperature without using electricity. The coating replaces conventional white pigments with nano-to-microscale air voids that reflect sunlight and release heat towards the sky. Tests showed the surface stayed about 6°C below ambient temperature in Arizona and 3°C below it in Bangladesh.

Recent studies shed light on how some ancient brains manage to endure over time. The availability of oxygen is pivotal in influencing the survival of brain proteins post-mortem. In moist, low-oxygen environments, decomposition favors protein cross-linking, which fortifies these proteins against degradation. This explains the remarkable preservation of certain ancient brains while other bodily tissues succumb to decay.

Archaeologists found a 1,500-year-old infant burial in northern Peru. The child was buried with whistles, a rattle, and a sculptural vessel. This burial displays patterns characteristic of the ancient Moche culture. The discovery occurred in a residential area, offering insights into daily life. Excavations continue to expand understanding of the Moche community.
