Article: In the past, friendships were greatly limited by time, space and attention; increasing home and workplace mobility has made it even harder to keep social relations over time. Through a combination of user controls, new technologies and changing standards of social behavior, Facebook is freeing us from these limitations, making friendships more accessible, pleasant and diverse than ever before. First, Facebook allows you to find and rediscover friends and then reminds you of these connections, so that you are less likely to fall out of touch with the long-lost school friend, or the family member in a different country. 'Second, Facebook creates an environment that allows you to interact easily with others : you can share your photos,videos,links and thoughts with your friends, and respond to what they share in turn. Third, Facebook's unique technical system helps you to discover your friends,most valuable stories. These technologies allow people to keep and enrich friendships that they might otherwise have been unable to keep. The effect of this is very great. A recent study by Keith Hampton for the Pew Internet and American Life Project discovered that users of social networking websites have larger, more diverse social circles, online and offline. This outcome comes at no cost to one's closest relationships, which are kept in person and over the phone. Instead, the hour that the average user spends each day socializing on Facebook comes at the expense of less social activities, such as the three or so hours a day the average person spends watching television. Time may limit our ability to keep social ties, but our desire for social communication is limitless. Just as boats have allowed us to cross oceans and vehicles have allowed us to move mountains, Facebook is a tool that allows us to stay more deeply connected with a larger and more diverse set of friends.
Answer: Change the behavior towards your friends.

Article: Science Daily (Apr. 27, 2008)-- Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean and aboveground herbivorous insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. This way, aboveground insects are warned that the plant is already "occupied". Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. This messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for, the same plant. In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean insects and 'vice versa . It seems that a mechanism has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition. Through the "green telephone lines", subterranean insects can also communicate with _ , namely the natural enemy of caterpillars . Parasitic wasps lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more insects for their eggs. The communication between subterranean and above- ground insects has only been studied in a few systems. It is still not clear how widespread this phenomenon is, say the researchers.
Answer: By sending signals through the leaves.
