The Dangers of Mobile Radiation

As technology has advanced a lot during the las decades, people are more and more afraid of the effects mobile phone radiation may have on our bodies.In fact, an uncountable number of studies have shown how harmful radiation can be. Among others, a study published by Dr. Carlo pointed out the following facts:

• Originally developed for the Department of Defense, cell phones devices were never tested for safety. They entered the marketplace due to a regulatory loophole.

• Questions about cell phone safety arose in the early 1990s, when a businessman filed a lawsuit alleging that cell phones caused his wife’s death due to brain cancer.
  
• To address the questions surrounding cell phone safety, the cell phone industry set up a non-profit organization, Wireless Technology Research (WTR). Dr. George Carlo was appointed to head WTR’s research efforts.
  
• Under Dr. Carlo’s direction, scientists found that cell phone radiation caused DNA damage, impaired DNA repair, and interfered with cardiac pacemakers.
  
• European research confirmed Dr. Carlo’s findings. Studies suggest that cell phone radiation contributes to brain dysfunction, tumors, and potentially to conditions such as autism, attention deficit disorder, neurodegenerative disease, and behavioral and psychological problems.
  
• Dr. Carlo brought safety information about cell phones to the public through his book, Cell Phones: Invisible Hazards in the Wireless Age, and by creating the Safe Wireless Initiative and the Mobile Telephone Health Concerns Registry.
  
• The best protection against cell phone radiation is keeping a safe distance.
  
• Always use a headset to minimize exposure to harmful cell phone radiation. 

On the other hand, there have been many studies have tried to show that mobile phones are not as damaging as some people are trying to make us believe. However, there were some drawbacks on those studies such as not being any biological hypotheses tested in the study or not having into account how much technology has evolved since when the study was carried out.

Scientific Culture: Second Term.

Some months ago I wrote a few lines about what I expected about the subject, unfortunately, Scientific Culture hasn't lived up to expectations for the moment. I expected to learn about science in a more practical way, but much to my disapointment we have just read about science instead of doing science. I would call it History of Science rather than Scientific culture.

For the second term we have already started working on teams, what I enjoy more than working on my own, and being us the ones in charge instead of having a passive attitude in class. What's more, the subjects we are working on are more enjoyable than the ones in the first term.

Evolution

The main and most important theory for evolution is Darwinism, and it defends that there are two main causes for evolution to happen: DNA modifications and natural selection. Sometimes when DNA is being copied and pasted some errors occur and if this error doesn't kill the animal, it will carry on with evolution. Natural selection makes unadaptable species disappear, so only the most adaptive animals survive. This theory was developed by Charles Darwin, a British biologist and geologist. Darwin's theory was based on Lamark's theory and developed it.

There are other theories like creationism that defend the religious view of human creation. They believe that God created Adan and Eve and put them in the paradise, until they were kicked out of there.

There has been a great controversy through the years between this two theories.
