What is heat conduction?

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research. For example, knowing how ...

Sponge creates steam using ambient sunlight

How do you boil water? Eschewing the traditional kettle and flame, MIT engineers have invented a bubble-wrapped, sponge-like device that soaks up natural sunlight and heats water to boiling temperatures, generating steam ...

Temperature differences give rise to electricity

More than half of today's energy consumption is squandered in useless waste heat, such as the heat from refrigerators and all sorts of gadgets and the heat from factories and power plants. The energy losses are even greater ...

Multi-scale simulations solve a plasma turbulence mystery

Cutting-edge simulations run at Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center (NERSC) over a two-year period are helping physicists better understand what influences the behavior ...

The Gulf Stream has increased steadily over the last century

Together with colleagues, Lars H. Smedsrud, professor at UiB and researcher at the Bjerknes Centre for Climate Research, have examined 100 years of research results to see how the ocean transport has evolved.

How physics explains the evolution of social organization

A scientist at Duke University says the natural evolution of social organizations into larger and more complex communities that exhibit distinct hierarchies can be predicted from the same law of physics that gives rise to ...
