Radiology often is used to detect tumors and cancerous malignancies. But, once found, how is cancer cured? Researchers today are making astounding discoveries that can help cure cancers or put this disease into remission. The following top 20 most influential cancer researchers have offered tremendous contributions to cancer science. [click to continue…]
Radiology technicians know that there is radiation everywhere. And we all know that radiation comes from the sun. Indeed, we have received so much information in recent years about how excessive sun exposure can lead to skin cancer, and how excessive tanning can lead faster aging, that we are irrationally worried about sun exposure. We forget that sun exposure has some benefits as well as problems.
The sun’s radiation can help processes in the body work better. But, as with all things related to health and wellness, the key is moderation. Just because the sun offers some health benefits doesn’t mean that you should go crazy. You still need to wear sunscreen if you’ve been in the sun for more than 10 minutes or so; it’s all about common sense. Here are 25 benefits of sensible sun exposure:
If you have read the book, Exposed, you might understand the difference between the U.S. and the European Union (EU) when it comes to health measures. The EU uses the precautionary principle that states that if an action or policy has a suspected risk of causing harm to the public or to the environment, in the absence of scientific consensus that the action or policy is not harmful, the burden of proof that it is not harmful falls on those who advocate taking the action. In the U.S., the burden of proof to date falls in the hands of the manufacturers’ witnesses when it comes to cell phone use. [click to continue…]

Science has brought us many exciting discoveries. Laboratories are great places to make discoveries, since they are generally sterile and equipped with what is needed to perform experiments. Sometimes, lab experiments yield the results expected, and at other times, lab discoveries have been made by accident. But no matter how they are made, some lab discoveries have become a regular part of life. Here are 10 famous lab discoveries that history remembers — and you will probably recognize:
