Black, green, white, and oolong teas all come from the same plant known as Camellia Sinensis.
The more processing the leaves of the plant undergo, the darker they will turn. (Green and white being steamed quickly, black and oolong being dried and fermented.)
Regardless of the processing method, brewed tea not only tastes good, but can have many health benefits as well;
- Tea contains antioxidants. Antioxidants can help slow down the aging process, and help cells regenerate and repair. Many studies suggest antioxidants also assist our bodies in preventing cancer.

A newly discovered material called ‘black silicon’ is between 100 and 500 times more sensitive to light than conventional silicon, and could be used to revolutionize solar energy generation.
The material was discovered when a team of Harvard University scientists shone an ultra-powerful laser (briefly producing the same amount of energy as the sun falling on the entire surface of the Earth) on a silicon wafer, before adding sulphur hexafluoride. The result was a silicon wafer that looked black to the naked eye, but when examined under an electron microscope turned out to be covered with a massive amount of ultra-tiny spikes.
