A polymer coating that acts as a spontaneous air cooler and can be applied like paint on rooftops, buildings, vehicles and even spacecraft has been invented by scientists. The researchers from Columbia University used a technique that gives the exterior passive daytime radiative cooling (PDRC) polymer a porous foam-like structure. PDRC is a phenomenon where a surface spontaneously cools by reflecting sunlight and radiating heat to the colder atmosphere. They also created coloured polymer coatings with cooling capabilities by adding dyes.
Termites can build societies without any males: All-female termite societies have been discovered for the first time, according to a study published in BMC Biology. Among more than 4,200 termites collected from coastal sites in southern Japan, the researchers did not find a single male. All-female lineages have previously been documented in a few ant and honey bee species, but their colonies are already dominated by queens and female workers. Termites are known for having colonies in which males and females both participate in social activities. This research is the first to demonstrate that males can be discarded from advanced societies in which they once played an active role. Of the 74 mature colonies they studied, 37 were asexual and exclusively female.
TINY WRESTLING STARS: Mexico’s lucha libre, a popular form of wrestling, long featured dwarves in a deeply demeaning role: they were ‘mascotas’ — a word that can mean both mascot and pet — for full-size wrestlers. But a new generation of little people are now rising lucha libre stars in their own right, headlining the main events on their fight cards
