Alzheimers Infrared Helmet

Scientists are set to test an experimental helmet which they believe can reverse the symptoms of Alzheimer's disease. Looking like a prop from an old science fiction movie, this odd-looking helmet is designed to safely emit low levels of infra-red light into the brain and stimulate the growth of brain cells.

Although the therapy is a potentially revolutionary treatment, scientists practically stumbled upon the application. Infra-red light was being studied as a treatment for cold sores, when scientists discovered that the light stimulated cell growth. Scientists at the University of Sunderland tested the infra-red light theory on mice and reported promising results - it improved learning ability and reversed memory loss.

The study of the effects of infra-red light therapy on people will begin this summer. Participants in the study, about 100 people with age-related memory problems, will wear the helmet for about 10 minutes a day. Scientists are hoping to see the same beneficial results in humans as they saw in mice.

If the results show that infra-red light therapy is able to reverse the memory loss and anxiety associated with dementia, it could change the lives of the hundreds of thousands of people who suffer from Alzheimer's disease.

Laser Hair Removal

Laser Hair Removal

The FDA approved the first medical laser for hair removal in the mid 1990's. Since that time, the use of lasers for cosmetic hair removal has continued to grow in popularity. The technology has continued to improve as well, providing better results and safer treatments for people of more diverse skin and hair colors. At the onset, laser hair was only for people with dark hair and light skin. The new advancements have made it possible to treat people with darker skin, tanned skin, and blond, gray, or red hair.

Both men and women are searching for effective ways of removing unwanted hair. The most common form of hair removal is shaving, but it is a very temporary method. Many people have tried waxing, but it is painful and the results are temporary as well. Electrolysis is a permanent hair removal option, but it is painful, as well as time-consuming and expensive for large treatment areas. Laser hair removal has become a popular cosmetic procedure because it is able to treat large body areas relatively fast with a minimal amount of pain and long-lasting results.
