    Bad Environment & Lifestyle (stress) Cause Most Cancers In Western Countries

    The medical industry loves to claim that the increase in new cancer cases we have been seeing across all Western countries (and all other countries adopting the lifestyle of the Western world) are simply due to improved diagnostics and longer lifespan of modern people. Both of these claims are...

    Sperm Count (Biomarker Of Male Health) In The West Has Declined By 60% Since The 1970s

    This topic has been discussed on the forum a few times before but the humbers quotes by recent studies usually hovered around 20% - 30%, which did not cause much alarm among endocrinologists. Now, this larger study shows that the decline in male fertility is much worse than previously thought...

    Genes Do Not Matter (again) - Individuality Is An Inevitable And Unpredictable Result Of Development

    I posted quite a few studies showing that genes do not matter much when it comes to determining the "fate" of the organism, be that health, personality or intelligence. This new study went a step further and examined the development of genetically identical organisms under the same environmental...

    Stroke Rates Have Almost Doubled In Young Adults

    I posted recently about two studies showing rapidly increasing incidence of colon cancer, and diabetes in young adults. At least for the colon cancer cases, the respective study itself stated that neither genes, nor obesity can explain the increase. Breaking News: Colorectal Cancer Rates In...

    Breaking News: Colorectal Cancer Rates In Young People Have Doubled

    I don't know which is sadder - this front page news reported today on CNN, or the fact that the pharma/medical press continues to call colorectal cancer largely a "genetic" phenomenon. Surely, there must be an evil gene that swept through the population in just 2 decades and targeted the young...

    The Neo-Darwinian Theory Of Evolution Is Incomplete Without Lamarck

    After decades of denial that environmentally-driven traits can be inherited, more and more prominent geneticist are calling for a major revision to the Neo-Darwinian theory of evolution. There is nothing modern about the so-called Modern Evolutionary Synthesis, and it needs to be revised or...

    Brain Metabolism Predicts Fluid Intelligence And Creativity

    I am seeing more and more of these studies lately, and I consider it a good sign even though they always contain a disclaimer about the predominantly genetic component of non-fluid intelligence. Little by little, science is making an 180-degree turnaround that embraces the environment as key in...

    Cancer Overwhelmingly Due To Environment

    http://www.bbc.com/news/health-35111449 "Earlier this year, researchers sparked a debate after suggesting two-thirds of cancer types were down to luck rather than factors such as smoking. The new study, in the journal Nature, used four approaches to conclude only 10-30% of cancers were down to...

    Sexual Preferences May Be Modifiable By Enviromnent & Drugs

    There was a study several years showing that mice given pCPA lose preference for females and would mate with both males and females. The mainstream explanation is that the drug made mice gay. I think the more likely explanation in that case was that the increased libido made mice not care about...
