How do you define a species? To non-biologists this might sound like the most basic and most obvious of all questions. Yet, there are few matters that stir up more intense discussions between scientists.
Have you ever wondered how our power grid works? If it isn't part of your job, you probably haven't.
If you have an unusually pretty cat and dream about cloning it one day, you might as well stop dreaming. Two cats with the exact same gene pool can actually look totally different.
A decrease in permafrost (cryotic soil) will follow climate change and a rise in temperature. This could have serious consequences. We might see an increase in greenhouse gasses, a greater possibility of landslides and live under the threat of monster waves.
Was a giant wave involved in the sinking of the oil tanker Prestige off the Spanish coast? We don't know, but there have been speculations on the possibility of a giant wave due to a phenomenon called crossing sea.

“When human activities pose a threat to the cod, we are in a way threatening ourselves,” says Professor Nils Chr. Stenseth.
Solar power is the renewable energy source that has the greatest potential to solve the world's energy challenges. The University of Oslo is now building a world-leading research group in this field.
