Repeated Genetic Test Saliva Shows Your Physical Age.
A rejuvenated study that uses a saliva sample to predict a person's age within a five-year collection could prove useful in solving crimes and improving patient care, University of California, Los Angeles geneticists say. Their examination focuses on a process called methylation, a chemical modification of one of the four edifice blocks that make up DNA. "While genes partly condition how our body ages, environmental influences also can change our DNA as we age.
Methylation patterns shift as we grow older and furnish to aging-related disease," principal investigator Dr Eric Vilain, a professor of Possibly offensive manlike genetics, pediatrics and urology, said in a UCLA news release. He and his colleagues analyzed saliva samples from 34 pairs of similar male twins, aged 21 to 55, and identified 88 sites on their DNA that strongly linked methylation to age.
They replicated their findings in 31 men and 29 women, superannuated 18 to 70, in the composite population. The yoke then created a predictive model using two of the three genes with the strongest age-related coupling to methylation.

Dirty Water Destroys People

Groundwater and integument water samples entranced near fracking operations in Colorado contained chemicals that can disrupt male and female hormones, researchers say. These chemicals, which are cast-off in the fracking process, also were present in samples taken from the Colorado River, which serves as the drainage basin for the region, according to the study, which was published online Dec 16, 2013 in the daily Endocrinology. "More than 700 chemicals are second-hand in the fracking process, and many of them provoke hormone function," study co-author Susan Nagel, an assistant professor at the University of Missouri School of Medicine, said in a review news release.
And "With fracking on the rise, populations may come greater health risks from increased endocrine-disrupting chemical exposure". Exposure to these chemicals can bourgeon cancer risk and hamper reproduction by decreasing female fertility and the quality and volume of sperm, the researchers said. Hydraulic fracturing, also called fracking, is a controversial process that involves pumping water, sand and chemicals intensely underground at high pressure.
The purpose is to craze open hydrocarbon-rich shale and extract natural gas. Previous studies have raised concerns that such drilling techniques could bring on to contamination of drinking water. The oil and gas industries strongly disputed this unfamiliar study, noting that the researchers took their samples from fracking sites where unintentional spills had occurred. Steve Everley, a spokesman for industry group Energy in Depth, also disputed claims in the probe that fracking is exempt from the federal Safe Drinking Water Act and the Clean Water Act.
He said the researchers grossly overestimated the bunch of chemicals Euphemistic pre-owned in the process. "Activists promote a lot of bad science and shoddy research, but this study - if you can even apostrophize it that - may be the worst yet. From falsely characterizing the US regulatory environment to suite out making stuff up about the additives used in hydraulic fracturing, it's hard to see how scrutinize like this is helpful. Unless, of course, you're trying to use the media to help you scare the public".
