The white, cloudy contrails that airplanes often leave in the sky may be full of ice crystals, but they're warming the globe. They trap infrared radiation on its way out into space which slightly heats the Earth.

With water guns, buckets, and even elephants dousing people with their trunks, pretty much everyone gets soaked during this Thai New Year festival. It's a symbolic fresh start, and a welcome respite from the heat!
Camp Warrior teaches teamwork. Twenty-six teens braved the Louisiana heat, a midnight thunderstorm, and plenty of chiggers and poison ivy at North Toledo Bend State Park -- solving problems together as they came up.
In Northern Africa, when a meal is spicy enough to make your sinus runny, the food is complimented for cleaning out the airways. That spicy heat often comes from harissa.

When a popcorn kernel is heated, the starch inside liquefies and the pressure builds until the seed coat breaks. The liquefied starch froths outward, cooling and solidifying in a fraction of a second!

Under extreme heat conditions, the body's organs begin to shut down. The brain, too, is affected by reduced blood flow. That's why people in the throes of heat illness begin to make poor, often life-threatening decisions.

Salty water molecules tend to diffuse into freshwater nearby. By placing a permeable membrane between the two bodies, experimenters aim to put the heat energy generated by osmosis to use.
Americans flush 350 billion kilowatt-hours of energy into the sewers each year. Cities are taking notice, and taking steps to install sewage heat recovery systems to capture the energy from the effluence.

Huddle movement caused by the selfish behavior of individual penguins, each one jockeying for the warmest position, ends up distributing heat throughout the group and leads to benefits for everyone.
