Even TINY traces of pesticides found to cause infertility in insects, scientists discover

(Natural News) How much of a pesticide do you think it takes to cause harm? For insects, the amount to cause harm is even smaller than scientists could have ever hoped to imagine. New research has highlighted just how dangerous chemical pesticides really are, yet for some reason these literal poisons continue to sit on...

These glowing images of yeast (Schizosaccharomyces kambucha) reproductive cells show an example of a selfish gene at work. Here, the selfish gene boosts its chances of being passed to the next generation by producing both a toxin (stained cyan) and an antitoxin (stained magenta). Cells with a copy of the selfish gene are protected by the antitoxin, left and bottom ovals. Those without the selfish gene are destroyed by the toxin. Scientists suspect that selfish genes could be operating throughout many organisms’ genomes, possibly having a major impact on how genetic material is inherited over generations. Credit: Imag...

(Natural News) As promised, I’ve now released a one-hour science lecture video that documents the multiple vectors through which people of African descent are being targeted for depopulation, covert infertility and extermination by “science” and “medicine.” (Watch the full video lecture below.) This video lecture documents the pattern of heavy metals poisoning, medical experimentation, organ...

This study was designed to examine whether the detrimental effects of long-term copper consumption on sperm quality and testis function of Wistar albino rat could be prevented by L-carnitine therapy. The parameters included were sperm quality (concentration, viability, motility, and morphology), histopathology, serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), serum urea, serum creatinine, serum testosterone and testis antioxidant enzyme levels (superoxide dismutase and glutathione-S-transferase), and biomarkers of oxidative stress (lipid peroxidation and expression of heat shock protein 70 in t...

Abstract NRH: quinone oxidoreductase 2 (NQO2) is a cytosolic and ubiquitously expressed flavoprotein that catalyzes the two-electron reduction of quinone to hydroquinones. Herein, we assessed the protein expression, subcellular localization and possible functions of NQO2 in mouse oocyte meiotic maturation and embryo development. Western blot analysis detected high and stable protein expression of NQO2 in mouse oocytes during meiotic progression. Immunofluorescence illustrated NQO2 distribution on nuclear membrane, chromosomes and meiotic spindles. Microtubule poisons treatment (nocodazole and taxol) showed that fi...

Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

Conclusion This large study found an association between having the MeNZB vaccine and a reduced likelihood of being diagnosed with gonorrhoea. But it's difficult to form any firm conclusions because of the nature of the case and control groups. For example, given that both groups were sexually active, we don't know why the majority of people with gonorrhoea didn't also have a chlamydia infection, and how this may have affected the results. It could just be down to pure chance and have nothing to do with the vaccine. So before we celebrate the alleged "cure of gonorrhoea", there are many things to consider: T...

Meiotic drivers are selfish genes that bias their transmission into gametes, defying Mendelian inheritance. Despite the significant impact of these genomic parasites on evolution and infertility, few meiotic drive loci have been identified or mechanistically characterized. Here, we demonstrate a complex landscape of meiotic drive genes on chromosome 3 of the fission yeastsSchizosaccharomyces kambucha andS. pombe. We identifyS. kambucha wtf4 as one of these genes that acts to kill gametes (known as spores in yeast) that do not inherit the gene from heterozygotes.wtf4 utilizes dual, overlapping transcripts to encode both a g...

We presently review the biophysical mechanisms of lead poisoning that contribute to male infertility. Environmental and occupational exposure of lead may adversely affect the hypothalamic-pituitary-testicular axis, impairing the induction of spermatogenesis. Dysfunction at the reproductive axis, namely testosterone suppression, is most susceptible and irreversible during pubertal development. Lead poisoning also appears to directly impair the process of spermatogenesis itself as well as sperm function. Spermatogenesis issues may manifest as low sperm count and stem from reproductive axis dysfunction or testicular degenerat...

All of us understand the central importance of nutrition in our lives . We know we need to eat good quality food if we want to lead a healthy and happy life.However, because of our multi-billion food processing industries , we end up stuffing ourselves  with poisons which end up killing us faster. This is why there is such a great demand for organic foods, which are not contaminated with chemicals. However, the problem is that organic foods are seen to be exotic and expensive.We need to look at alternative options which make organic farming a lot easier , cheaper and more convenient than traditional farming.The proble...

Recently a father contacted CEH with concerns about his 16-year-old son's health. The teenager had purchased nicotine-laced e-liquids from a website that had no age verification or nicotine warnings. The packaging on the e-liquid also had no warning labels, despite the known health consequences of exposure to nicotine. Angry and frustrated at the lack of rules on e-cigarettes, the dad told us, "If you can help get them to do the right thing, that would be awesome." Parents around the country are now realizing that they need to learn more about e-cigarettes and their children's health. According to recent research...
