I suppose in the near future the mankind may carry out such space projects as making interplanetary flights to Mars and sending probes to Venus and Mercury.
Some of the urgent problems scientific minds are working at nowadays are finding a cure for serious diseases like cancer and AIDS, finding alternative sources of energy as well as studying particles smaller than atoms and creating new materials.
A real breakthrough of the 21st century is nanotechnology. It’s the technology of materials of microscopic size. Nanotechnology can be used to improve the efficiency of traditional materials, to seek and destroy cancerous tissue. There is even speculation that materials can be developed that will allow machines to repair themselves in the same way as the human body does. However, some people are already expressing their concerns that nanotechnology may be difficult to control. For example, nanoparticles are so small that they can cross biological barriers and penetrate tissues and organs which can cause DNA mutation. I think scientists should continue their research as nanotechnology can make people’s lives better. However, they must be cautious not to overdevelop the technology before we know all of the risks and possible dangers.
