Could Paint Reduce Your Air-Con Use?
Scientists in Singapore have developed a new type of ‘passive cooling’ paint, that could potentially help keep homes cool, even in heat and humidity.
The paint combines three cooling strategies – radiative cooling, evaporative cooling and solar reflection – to hold water and slowly release it, essentially allowing a house to ‘sweat’.
Tests showed homes using the paint used 30-40% less electricity for air conditioning compared to other homes.
The research was published in a report in Science and you can read more here.

Rare Penguin Chick Hatched at UK Zoo
A rare South American Humboldt penguin chick has been successfully hatched at Chester Zoo in the UK, after a pair of male penguins stepped in to help raise one of two eggs laid by another breeding pair.
