Nuclear Power

Nowadays nuclear power is safe and harmless for our environment. The experts have worked hard to make nuclear generator does not directly produce sulfur dioxide, nitrogen dioxide, and carbon dioxide which is dangerous for our body. Also it was successfully proved that ventilation system with many filters can block radioactive gas. For the water pollution, people do not need to worry because, now the water that used to bring the heat from the system is not contains radioactive material anymore. For example, nuclear power gives France the cleanest air of any industrialized country, and the cheapest electricity in all of Europe.

New Cholera Vaccine

Cholera, an intestines disease caused by bacteria Vibrato cholera, has been rarely heard. The World Health Organization (WHO) notes, cholera is no longer founded in industrial country and some developing country, including Indonesia. But that doesn't mean that cholera has been already extinct. According to WHO, number of cholera cases have increased by 30% since 2004. This disease is often happened in Africa, South America and half of Asia.

Many years ago, scientists had invented cholera vaccine. But it is so expensive. The vaccine has to be kept in special cooling box because cholera usually happened in remote areas. Moreover, if the vaccine has been taken out from the box, it won't last for long and have to be used immediately. In Japan, the cost that the government has to pay to provide the vaccine is about US$ 200 million - US$300 million every year.

Research team in Japan has successfully invented the new cholera vaccine through rice gene therapy method. "We develop a new vaccine technology that no longer need special cooling boxes and inject needles, so it is cheaper and comfortable." said Dr. Tomori Nochi, one of the researchers. This new vaccine is really good for developing country. Tomori sure that soon this new vaccine will be used worldwide. But he said that the best way to prevent cholera, of course, is keep the water system and environment clean.
