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 ...

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 ...

How animals survive Norwegian winter nights

Norwegian mammals and birds have many different methods of surviving long, intense winter nights. A biologist from the Norwegian University of Science and Technology (NTNU) University Museum reveals their secrets for survival.

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 ...
