Here’s a startling thought: the human genome contains ancient viruses . Researchers recently detected a 100-million-year-old virus called a human endogenous retrovirus (HERV)—that would have infected our ancestors when dinosaurs roamed the Earth—in the blood of pregnant women. They are still puzzling over how retroviruses might affect us in the long term. Eight percent of the human genome is made up of ancient viruses and scientists are still trying to puzzle out their function. Three scientists, led by Gkikas Magiorkinis of the National and Kapodistrian University of Athens , wrote an article available online the end of September for Trends in Microbiology , delving into the mystery behind HERVs. They said, “Are they merely fossils that, like mosquitoes in amber, were stuck and preserved in large host genomes while their functions decayed?” They noted the 100-million-year-old retrovirus, first detected by another research group, “became a human gene that is expressed in embryos and cancers , and can be detected in the blood of pregnant women.” Related: University of Queensland scientists uncover an ‘explosion’ of new life forms Retroviruses insert a DNA copy of their RNA into a genome, according to IFLScience – this has devastating consequences with the human immunodeficiency virus, or HIV , for example. The 100-million-year-old HERV looks to be inactive during most stages, with low expression in many normal tissues, but it is expressed in the placenta, some stem cells, and cancer tissues like those of ovarian cancer, according to the scientists. The expression pattern “suggests potential roles for manipulation of stem cells and early life events, which could have very important impacts on adult diseases.” IFLScience points out the find has raised more questions than it solves – the three researchers suggest a hypothesis at the end of their paper, but no definitive conclusions. They say scientists should explore the roles of endogenous retroviruses to pin down potential anticancer treatments. Via IFLScience Images via freestocks.org on Unsplash and Pixabay

Most Doctors Don’t Warn Pregnant Mothers About Environmental Risks To Unborn Children

Comments Off on Most Doctors Don’t Warn Pregnant Mothers About Environmental Risks To Unborn Children

A troubling new nationwide survey conducted by researchers at the University of California, San Francisco finds that most doctors do not inform patients about environmental risks they might encounter while pregnant. Although they do routinely address issues like smoking, alcohol and diet, only 19 percent said they talk to their pregnant patients about pesticides and just 12 percent discuss air pollution with pregnant mothers. This is very disturbing news, considering that environmental risks have been linked to a vast array of health issues for children , ranging from learning disabilities to cancer.

Gordon Gallup’s “Natural” Remedy to Morning Sickness Might Be More Than You Can Stomach.

Comments Off on Gordon Gallup’s “Natural” Remedy to Morning Sickness Might Be More Than You Can Stomach.

Based on SUNY-Albany Psychologist Gordon Gallup’s research, just a spoonful of semen a day will keep morning sickness at bay for mothers-to-be. Gallup’s research suggests pregnant women feel nauseous and vomit as a reaction to the “foreign” sperm that has impregnated them. The practice of oral sex can help build up the mother’s “tolerance” and make her less queasy. Naturally, fathers all over the world applauding (or giving high-fives) and pregnant women (at least this one) are rolling their eyes.

Comments Off on Amazing Delivery! Shark Bites Pregnant Shark – Babies Emerge

Visitors at Kelly Tarlton’s Underwater World sure got their money’s worth recently!  Visitors at the New Zealand aquarium witnessed a shark perform an unplanned and unconventional “cesarean section” on another shark! Acting as midwife, the smart shark apparently knew what the Auckland aquarium’s staff did not – another shark in the aquarium was pregnant.  Although it is common for sharks to nip at one another, this particular shark took a great big bite out of the pregnant shark’s side.
