Chemicals Released During Natural Gas Extraction May Harm Human Reproduction and Development

Scientists draw conclusions after review of more than 150 studies; suggest further scientific study

COLUMBIA, Mo. – Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or “fracking,” to release natural gas from underground rock. Recent discussions have centered on potential air and water pollution from chemicals used in these processes and how it affects the more than 15 million Americans living within one mile of UOG operations. Now, Susan C. Nagel, a researcher with the University of Missouri, and national colleagues have conducted the largest review to date of research centered on fracking byproducts and their effects on human reproductive and developmental health. They determined that exposure to chemicals released in fracturing may be harmful to human health in men, women and children and recommend further scientific study. (more…)

Sex at zero gravity

University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular “highways” that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube. “Just like during human reproduction, the sperm cells in plants are delivered to the egg by a cylindrical tool. Unlike the delivery tool in animals, the device used during plant sex consists of a single cell, and only two sperm cells are discharged during each delivery event,” explained Professor Anja Geitmann of the university’s Department of biology. “Our findings offer new insight into how life evolved on Earth and are significant with regards to human health, as a traffic jam on these highways that also exist in human cells can cause cancer and illnesses such as Alzheimer’s.” (more…)
