Scientists find cell phone radiation exposure creates cellular imbalances known to cause cancer in 92% of peer reviewed studies on ROS (Reactive Oxygen Species). RF Safe suggest precautionary measures to reduce excessive RF exposure even at athermic levels. San Francisco, CA (PRWEB) April 22, 2014 According to RF Safe, Scientists confirm non-ionizing cell phone radiation and ionizing UV radiation from the sun both produce a common bio-effect in living cells, the overproduction of...

Dangerous New Carcinogens
2014-01-07 08:10:02

April Flowers for redOrbit.com - Your Universe Online New compounds produced by certain types of chemical reactions, such as those found in vehicle exhaust or grilling meat have been found by a research team at Oregon State University. Their findings, published in Environmental Science and Technology, reveal that these compounds are hundreds of times more mutagenic than their parent compounds, known as carcinogens. The previously unknown compounds raise concerns about the health impacts...

A set of proteins involved in the body's natural defenses produces a large number of mutations in human DNA, according to a study led by researchers at the National Institutes of Health. The findings suggest that these naturally produced mutations are just as powerful as known cancer-causing agents in producing tumors. The proteins are part of a group called apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like (APOBEC) cytidine deaminases. The investigators found that APOBEC...

DNA Danger From Thirdhand Smoke
2013-06-21 04:52:23

Rebekah Eliason for redOrbit.com – Your Universe Online For the first time ever, thirdhand smoke has been found to cause significant amounts of damage to human cells. Thirdhand smoke is the toxic residue that attaches to almost all surfaces leaving a strong odor long after cigarette smoke has dissipated. The researchers from Lawrence Berkeley National Laboratory also discovered in this study that chronic exposure caused more DNA damage than acute exposure. Samples exposed to chronic...

An international team of scientists have shown at an unprecedented level of detail how cells prioritize the repair of genes containing potentially dangerous damage. The research, published in the journal Nature and involving academics from the University of Bristol, the Institut Jacques-Monod in France and Rockefeller University in the US, studied the action of individual molecules in order to understand how cellular repair pathways are triggered. The genetic information that forms the...

Researchers from Indiana University-Purdue University Indianapolis (U.S.A) and Umea° University (Sweden) report in a study published in the February 15, 2011, issue of PLoS Biology that a method by which cells repair breaks in their DNA, known as Break-induced Replication (BIR), is up to 2,800 times more likely to cause genetic mutation than normal cell repair. Accurate transmission of genetic information requires the precise replication of DNA. Errors in DNA replication are common and...

Brandeis lab reveals the connection between mutation and malignancy What if we could understand why cancer develops? We know that certain risk factors, such as smoking or excessive sun exposure, can increase the chances of developing this terrible disease, but cancer can form in any tissue, and the cause is not always clear. One idea that has emerged is that for a cell to transform into a cancer cell it must suffer a large number of mutations affecting different genes needed to control cell...

Researchers at the National Institute of Standards and Technology (NIST) have developed a new chemical analysis method that has assisted researchers at the National Institute of Alcohol Abuse and Alcoholism (NIAAA), National Institutes of Health, in demonstrating a potentially important chemical link between alcohol consumption and cancer. Using this novel chemical assay, they have uncovered a chain of chemical reactions that, under physiological conditions, may lead from alcohol to a known...
