Smoking Can Damage the Body in Minutes

According to a research in the USA, smoking can damage the body in minutes rather than years. The research, funded by the US National Cancer Institute, showed that the formation of the chemicals which cause cancer occurs 15−30 min after smoking a cigarette. These chemicals “react with DNA to produce adducts that can cause mutations and initiate the carcinogenic process.”

Looking for Another Earth

On March 7, 2009, NASA launched the Kepler Mission, a space observatory designed to discover Earth-like planets outside the Solar System. The search for such planets is everything but simple. Since 1992, astronomers have announced the confirmed detection of 518 extrasolar planets. However, most of them are massive giants, like Jupiter, which are less difficult to detect. The problem is that it is not yet possible to observe distant planets through direct imaging. Their existence can be only indirectly inferred. Watch the video below and find out how it works.
