TNA as Genetic Material

TNA is different with DNA and RNA from their constituent sugar molecules. If the RNA has Ribose sugars and DNA has deoxyribose, then TNA has Thirosa, so called as Therose Nucleic Acid.

TNA is currently not discovered its existence in nature. However, Chaput has been successfully made in the laboratory and bind to proteins. Chaput see that TNA turned into more complex and can function like RNA in binding proteins.

Chaput research about TNA is still early research. Chaput said the current research still faces obstacles because the limitations of technology to allow TNA to evolve in the laboratory.

In view of Chaput, TNA is also not the only one that is more primitive genetic material of DNA and RNA. "The most possible type in natural have a lot," Chaput said as quoted by New Scientist, Sunday (08/01/2012).

But, there are weaknesses in the view of Chaput. First, there is no trace that TNA is "cousin" of DNA and RNA. Second, no scientist who made TNA the same environmental conditions as when there is no life. much research remains to be done. Chaput study published in the Nature journal.

Future Energy

The prediction about the energy source on the future are probably wrong. The last prediction that mentioned on 1950s, nuclear energy will dominated the world energy source because of cheap production, can't be relied more. After the nuclear incident in Japan because of Tsunami disaster, nuclear energy will make bigger threaten to the human life, compared with the nature disaster itself.

The biggest trend affecting of global energy markets is the explosive growth of shale natural gas, something that virtually no one thought was even viable 20 years ago. Advance technology, new discoveries, unexpected economic crisis, environmental concern, all of these factors can skew our expectation about how we'll be powering our homes, cars and industries tomorrow. The prediction of the shortage of oil tomorrow or hear the sunnily optimistic scenarios of energy executives, keep this in mind that the future is really hard to predict.

Other alternative energy is still not satisfy. They can't provide the energy for all over the world. People still looking the alternative energy beside always modified many equipment of using other kind energy. if the oil is completely discharged, there are many possibilities if the industry and vehicle stops operating.
