A Fox News Science headline reads:
"Scientist injects himself with an ancient 'eternal life' bacteria" The news report states,"In effect, he's making him[self] a human guinea pig to see how what the newspaper calls 'eternal life' bacteria protects against cell damage and may hold the key to longevity." (http://www.foxnews.com/science/2015/10/01/scientist-injects-himself-with-ancient-eternal-life-bacteria/)
You can have eternal life without injecting yourself with bacteria (not that this would ever work anyway; sin is the problem). It's not a secret though it has been rejected by many. See below.
"Do You Have Eternal Life?"
The Bible presents a clear path to eternal life. First, we must recognize that we have sinned against God: "For all have sinned and fall short of the glory of God" (Romans 3:23). We have all done things that are displeasing to God, which makes us deserving of punishment. Since all our sins are ultimately against an eternal God, only an eternal punishment is sufficient. "The wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord" (Romans 6:23).
However, Jesus Christ, the sinless (1 Peter 2:22), eternal Son of God became a man (John 1:1,14) and died to pay our penalty. "God demonstrates His love for us in this: while we were still sinners, Christ died for us" (Romans 5:8). Jesus Christ died on the cross (John 19:31-42), taking the punishment that we deserve (2 Corinthians 5:21). Three days later He rose from the dead (1 Corinthians 15:1-4), proving His victory over sin and death. "In His great mercy He has given us new birth into a living hope through the resurrection of Jesus Christ from the dead" (1 Peter 1:3).
