Turned-down temperatures boost crops' penchant for production

Drought and heat put stress on plants and reduce grain yield. For some farmers, irrigation is the answer. Many of us assume the practice boosts crop yields by delivering soil water, but it turns out irrigation's cooling effect ...

A cooler home is right in your own back yard

Urban trees are an effective tool for reducing land surface temperatures for entire suburbs, and even cities. But as yet we don't know much about their localized effects, particularly in the places where cooling is most important—our ...

Tea trees crave water during hot and dry summer days

The iconic Australian tea tree (Melaleuca decora) is more vulnerable than native eucalypt species to extreme temperature and moisture stress, Western Sydney University researcher Anne Griebel has discovered. 

Coating helps electronics stay cool by sweating

Mammals sweat to regulate body temperature, and researchers from Shanghai Jiao Tong University in China are exploring whether our phones could do the same. In a study published January 22 in the journal Joule, the authors ...

How aerosols affect our climate

For many, the word "aerosol" might conjure thoughts of hairspray or spray paint. More accurately, though, aerosols are simply particles found in the atmosphere. They can be human-made, like from car exhaust or biomass burning, ...

Running an LED in reverse could cool future computers

In a finding that runs counter to a common assumption in physics, researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away.
