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.

Relevant Scientist: Mileva Maric

This is an article about Mileva Maric, a brilliant person, who married Albert Einstein and condemned herself to be in the shadow of her husband.

She was born in Serbia (1875) and graduated in a maths and physics specialized secondary school, getting the best marks of her class, what allowed her to enter Royal School of Physics in Zagreb, where only men were accepted. Afterwards, she entered the Polytechnic Institute of Zurich, where she met her future husband, Albert Einstein.

Maric left her studies when, in 1901, she got pregnant without being married and she was forced to take cover in her sister's house. Their daughter was given in adoption.

Mileva Maric is known for having a great relevance in most of Albert Einstein's discoveries. Some may very well say that she was the one making the explorations, but that her husband stole her ideas.

I have chosen this scientist, since it shows the impact women have had in science, despite them being covered  by sexism.

MASS MEDIA & SCIENCE

In my opinion, science doesn't get the attention it should get from the media. We rarely read anything about scientific research in newspapers, TV or any other means of information. Given that, I can't help thinking that the media should give more importance to science, as if average people get to know about what scientists are doing, they could get a bigger support, not only economic, but also moral.

Seeing through sound.

This article was published in portalmedico.co the 8th December, 2012.

http://portalmedico.co/sistema-sonar-vision-permite-a-ciegos-ver-a-traves-del-sonido/

How is it possible to see thread sound? Ingeneers from the Hebrew University of Jerusalem have created a way to do so. Blind people are now able to perceive a face, identify objects, and even words through sound, using a revolutionary system called "sonar vision", which was based on the echolocation bats use.

The way it works is really simple: you inlay a video camera in your glasses which is going to be connected to your smartphone. This camera turns images into sounds that will be projected by your earphones and your brain would automatically make a mental image.

This is only useful if you were born blind.

Scientific Culture: what do I expect?

Actually, I don´t really know what to expect from this new subject as it´s the very first time it´s tought in our school. I guess I´ll work on my English while I study different aspects of science... And, of course, I´d really love to go on an exchange if the opportunity comes up!
