The breakdown is neurogenesis is a lifelong process that can be helped or hindered by what we do in our lives. Increasing neurogenesis improves learning, memory, and mood. Decreasing it impairs them.

Highlights of factors that increase neurogenesis:

  1. Learning
  2. Exercise- running
  3. Diet-
    1. Calorie restriction of 20-30%
    2. Intermittent Fasting
    3. Flavonoids-
      1. Chocolate
      2. Blueberries
    4. Omega-3 fatty acids
    5. Zinc
    6. Cumin
    7. Folic acid
    8. Caffeine
    9. Vitamin E
    10. Vitamin B
  4. Red Wine – resveratrol

Factors that decrease Neurogenesis

  1. Diet
    1. Saturated fats
    2. Sugar
    3. Vitamin E deficiency
    4. Vitamin B Deficiency
    5. Alcohol

Interestingly, healthy neurogenesis is not only related to better learning and memory, but also improved mood.

Diamond planets, climate change and the scientific method


  • ” It may come as a big surprise to many, but there is actually no difference between how science works in astronomy and climate change – or any other scientific discipline for that matter.

    We make observations, run simulations, test and propose hypotheses, and undergo peer review of our findings.

    We get together (usually in nice locations around the world) and discuss and debate our own pet theories, become friends and form a worldwide community.

    If you are a solid state physicist, an astronomer, or doing laser optics, the world is happy to celebrate your discoveries, use them in new products such as WiFi, and wonder about the growth in knowledge and technology.

    Of course we all make mistakes. But eventually the prevailing wisdom of the community triumphs and the field advances.

    It’s wonderful to be a part of that process.

    But on occasion those from the fringe of the scientific community will push a position that is simply not credible against the weight of evidence.

    This occurs within any discipline. But it seems it’s only in the field of climate science that such people are given airtime and column inches to espouse their views.

    Those who want to ignore what’s happening to Earth feel they need to be able to quote “alternative studies”, regardless of the scientific merit of those studies.

    In all fields of science, papers are challenged and statistics are debated. If there is any basis to these challenges they stand, but if not they fall by the wayside and the field continues to advance.

    When big theories fall, it isn’t because of business or political pressures – it’s because of the scientific process.

    Sadly, the same media commentators who celebrate diamond planets without question are all too quick to dismiss the latest peer-reviewed evidence that suggests man-made activities are responsible for changes in concentrations of CO2 in our atmosphere.

    The scientific method is universal. If we selectively ignore it in certain disciplines, we do so at our peril.”
