On a hot summer day, white clothing feels cooler than other colors due to reflecting—not absorbing—sunlight. Other colors like blue or black, will undergo a heating effect as they absorb light. To circumvent this heating effect in colored cooling films, researchers drew inspiration from nanostructures in butterfly wings.

TBH I think in most situations this excess office capacity could be most useful as affordable housing to bring a degree of sanity to rent and house prices.

Thanks. Just to clarify that was posted automatically by a bot. I'm playing with automated feeds, I'll try and adjust them so that they are more useful.

Yeah this would be a way for me to wean myself off that other site. If I knew I could see the top rated links from that place here it would help me personally to break that addiction
