Heavy cell phone users subject to cancers

Cell Phone – Cancer Link Found by Tel Aviv University Scientist; A new study finds an association between heavy cell phone use and tumors – An Israeli scientist, Dr. Siegal Sadetzki, has found a link between cell phone usage and the development of tumors. Dr. Sadetzki, a physician, epidemiologist and lecturer at Tel Aviv University, published the results of a study recently in the American Journal of Epidemiology, in which she and her colleagues found that heavy cell phone users were subject to a higher risk of benign and malignant tumors of the salivary gland.

Simple urine test detecting prostate cancer accurately

New, non-invasive prostate cancer test beats PSA in detecting prostate cancer, researchers report. Simple urine test leads to more accurate diagnoses, fewer false-positive results. – An experimental biomarker test developed by researchers at the University of Michigan more accurately detects prostate cancer than any other screening method currently in use, according to a study published in the February 1 issue of Cancer Research, a journal of the American Association for Cancer Research.

Research suggests why scratching is so relieving

Researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving ? and why it can be hard to stop. – Researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving ? and why it can be hard to stop. This is the first study to use imaging technology to see what goes on in the brain when we scratch.

Changes in X chromosome may lead to mental retardation

Various mutations of a small part of the X chromosome may lead to mental retardation, intellectual disability. – University of Adelaide geneticist Dr Jozef Gecz and a team of Belgium and UK scientists have achieved a major breakthrough in discovering the causes of intellectual disability.
