UNDATED (WVLT) -- Three new separate findings could affect the water supply, offer an alternative to a finger print identification, and ease your mind if you're balding.

Lead in fluoridated water
Researchers say if you want to prevent lead poisoning, limit fluoride. Their testing showed that fluoride added to water supplies boosts lead absorption in lab animals' bones, teeth and blood. Supporters of fluoride say its often added to water to reduce tooth decay, and the research subjected the test animals to more fluoride than is normally found in water. The researchers the fluoride levels provided during the testing are comparable with those commonly found in humans.

Forensic bacteria
Researchers may have discovered a method of forensic identification. It's the bacteria found on a person's skin. Researchers say that communities found living on a person's skin are different for each person. Even on people who wash their hands frequently, scientists say about 150 species of different bacteria can be present. For now, the new method is believed to be 70 to 90 percent accurate, but it's believed that figure will increase as the method is refined over time. CLICK HERE for more from the BBC.

Baldness and cancer
A receding hairline may be good news when it comes to a man's chances of developing prostate cancer. Research at the university of Washington school of medicine shows men who go bald by the age of 30, are less likely to develop prostate cancer. Scientists found that men developing bald spots saw a 30 to 45 percent reduction of prostate cancer. Of course men do not have control over when their hair begins the thin, still researchers say understanding the relationship between testosterone levels and prostate cancer is valuable.
