The Link Between Cancer and Mobile Phones
- by admin
The issue that using mobiles phones can cause cancer has been the topic of longstanding debates. Many studies have been conducted to prove and disprove claims regarding their connection. From time to time, the public is presented with evidence of new found links. The technological advancement of mobile phones has increased exponentially and the same can be really cause cancer. the theory ; Its is suggested that excessive use of mobile phones is associated with an increased risk of certain types of cancer.
This is because mobile phones emit radio frequency energy, which is a form of electromagnetic radiation. They emit electromagnetic waves or signal, which researchers claim to be the reason of a higher cancer risk for users. Another basis of theory is the position of the mobile phone when used. When a person uses his cells phone to call, the antenna use to pick up signal is placed near by brain.
Testing Breath Cavity

Cavity-enhanced direct optical frequency comb spectroscopy is a long and intimidating name for what is basically a medical breath test. You see the string words and you might think this is too complicated for you to understand. Spectroscopy is the study of spectra which is the case is the distribution of colored light. A pulsed laser beam was aimed into the cavity which was design to bounce laser light back and forth. By the time the laser light exited the cavity, it would have traveled several kilometers struck every molecule breathed into the cavity. This allowed comparative analysis of the light frequencies that were absorbed and the amounts. From there, the scientist were able to determine the molecules that were originally present in breath and their concentrations.
Think of the method as a way of sorting through the different molecules in human breath and finding traces of chemicals that could indicate disease.
Putting Computer Downtime to Good Use

Did you know that ordinary people like you and me help find a cure for cancer or vaccine against the human immunodeficiency virus or increase scientists understanding of many major disease? All it takes is a computer, Internet access and willingness ti donate our computer’s idle time to biomedical research. You read that right. Scientist in various universities in the United States need volunteers anywhere in the world willing to donate their computers’ idle time for a good cause. This practice is called “grid computing” or “distributed computing”. It involves breaking up what would otherwise be a huge, time-consuming task into smaller chunks to different people who would work on them. In this case, the chunks are being distributed to thousands of volunteered home computers worldwide.
They could also wait to use supercomputers sophisticated machines with the highest processing speed available but the waiting line for such computers is reportedly long.
Cleaning Up Nuclear Waste

Uranium waste is relatively weak, but it is still radioactive and therefore toxic. That is why scientist always look for ways to neutralize that is clean up the uranium once it combines with water, whether it is from natural ore deposits that leach into groundwater, the spent uranium fuel from nuclear facilities or the remains from uranium mining. The half life of uranium is very long: 4.47 billion years for uranium 238 and 704 million years for uranium 235.
That’s why nuclear waste can be present for a long , long time. Also, it is costly to keep leftover uranium. Unfortunately, uranium a heavy metal that has the highest atomic weight among the naturally occurring elements forms a stable bond with the two oxygen atoms of water. This very strong uranyl ion combination, which dissolves easily in water, makes it very hard to separate uranium from the water.
