Radiative cooling. Solar heat. All from one system, no electricity needed.
Study describes passive cooling system that aims to help impoverished communities, reduce cooling and heating costs, lower CO2 emissions

BUFFALO, N.Y. Passive cooling, like the shade a tree provides, has been around forever.
Recently, researchers have been exploring how to turbo charge a passive cooling technique known as radiative or sky cooling with sun-blocking, nanomaterials that emit heat away from building rooftops. While progress has been made, this eco-friendly technology isn’t commonplace because researchers have struggled to maximize the materials cooling capabilities.

Noise pollution affects marine life worldwide
Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper on 4 February.
Sound is fundamental to the sensory world of marine life. Animals, from jellyfish to whales, perceive and use sound for many aspects of their daily activities. They find food and each other by listening to the surrounding soundscapes, and hunt or seek shelter guided by acoustics. Global industrialisation of the ocean has led to the rise of noise pollution through noisy human activities in and around the water. Hans Slabbekoorn, associate professor at the Institute of Biology Leiden, investigates the effects of man-made sounds: ‘Noise pollution in and around the water has led to a decline in the presence of natu
A cacophony of industrial noise is disrupting marine animals ability to mate, feed, and even evade predators, scientists warn. With rumbling ships, hammering oil drills, and booming seismic survey blasts, humans have drastically altered the underwater soundscape.
LONDON - Far beneath the ocean surface, a cacophony of industrial noise is disrupting marine animals' ability to mate, feed and even evade predators, scientists warn. With rumbling ships, hammering oil drills and booming seismic survey blasts, humans have drastically altered the underwater soundscape - in some cases deafening or disorienting whales, dolphins and other marine mammals that rely on.

Far beneath the ocean surface, a cacophony of industrial noise is disrupting marine animals ability to mate, feed and even evade predators, scientists warn.
With rumbling ships, hammering oil drills and booming seismic survey blasts, humans have drastically altered the underwater soundscape – in some cases deafening or disorienting whales, dolphins and other marine mammals that rely on sound to navigate, researchers report in a metastudy published online Thursday and in the Friday edition of the journal
Science that examines more than 500 research papers.
Even the cracking of glaciers calving into polar oceans and the rattle of rain falling on the water’s surface can be heard deep under the sea, said lead author Carlos Duarte, a marine scientist at King Abdullah University of Science and Technology in Saudi Arabia.
