China launched the world's first quantum satellite on Tuesday, state media reported, in an effort to harness the power of particle physics to build an "unhackable" system of encrypted communications.

Essential Science: Sleep deprivation alters the brain differently

Sleep deprivation, over a long period, causes harm to the brain as well as increasing the risk of accidents. New research suggests the effect on the brain is not straightforward, with different regions and brain functions affected in varying ways.

Improving the wines of the world through DNA analysis

What makes one wine a great one and another a mediocre one? The constituent elements can be broken down: grapes, soil, bottling and so on. What about at the biological level? Scientists have been examining the DNA.
