Do you ever thought about your childrens as the specimens to be improved?


"Sometimes, we think why some people have high IQ and high intelligence are important in improving the society. Some might think can it happen when we change Genetic qualities of an individually."

Actually, Eugenics played a important role in these idea when social scientists thought about the nation's economic reasons. They thought Only healthy persons are fit to live in this society and diseased are not

Eugenics

Eugenics is the science of improving human race based on Genetics. Improving the traits of plants and animals through breeding programmes has been in practice for centuries.

Eugenics is highly controversial subject due to social, ethical and political reasons. The proponents of eugenics argue that people with desirable and good traits ( Good blood) should reproduce while those with undesirable characters ( bad blood ) should not. The advocates of Eugenics, however, do not force any policy, but they try to convince the people to perform their duty voluntarily. The objective of eugenics is to limit the production of people who are unfit to live in the society.

 System of Arranged marriages

Galton sociologist
Galton in Hereditary Genius (1869), proposed the system of Arranged marriages , between the men of distinction and women of wealth would eventually produce the gifted race. In 1865, the basic laws of heredity were discovered by the father of modern genetics, Gregor mendel . During the early 1990s , eugenics become a scientific study pursued by both biologists and social scientists. They sought to determine the extent to which human characteristics of social importance were inherited.

 

 

Eugenics in Nazi Germany

Germany developed its own eugenic programme during 1930s. A law on eugenic sterilization was passed in 1933. In a span of three years, compulsory sterilization was done on about 250,000 people, who allegdly suffered from hereditary disabilities, feeble mindedness, epilepsy, Schizophrenia, blindness, physical deformities, and drug or alcohol addiction.

The German Government commited many attrocities in the name of racial purity. Other countries, however do not support this kind of eugenics.

Antieugenics sentiment

Eugenics was dropped from organization and Publication names. The U.S department of health, education and welfare proposed guidelines encouraging each state to repeal their respective sterilization laws. Other countries, most notably china , continued to support Eugenics directed  programs openly in order to ensure the Genetic makeup of their future.

Let's see how humans are playing with the nature and what are the outcomes if eugenic research on humans continue one day.

Say thanks to your Telomerase if you look younger than your age naturally!!!

Did you know that people who look younger than their age also live a longer and healthy life that those who look older than their years ? It's true!

You already know that your cells reproduce by dividing in two. From the moment of conception until the final minutes of life, the trillions of cells in your body are regenerating through this process. Over the course of your early years, your cells continue to divide at will with little change in overall health and longevity. This is how the growth process unfolds: Your body is constantly rebuilding, repairing and renewing itself.

The prestigious journal Nature published a groundbreaking article in 1990 that introduced the world to an explanation of the genetic mechanism that involves something called the "Telomere". 

Telomeres and Telomerase

Telomeres are the special structures that prevent the continous loss of DNA at the end of the chromosomes during the course of replication and telomerase is the enzyme that adds the telomeric repeats to the end of your DNA . Telomere is also your biological clock. Each time your cells divide, a small end portion of the telomere is not copied making your telomeres shorter and shorter overtime.

As they shorten with each new division, they cause the chromosomes to fold differently exposing a diffrernt portion of your genome.This is how you can be so different at 72 than you were at 2. This process eventually signals to your cells to "grow old" and stop dividing and that cell line dies off.

Nutritional affects to grow younger

A growing body of research is showing that  certain Nutrients play a huge role in protecting or even increasing, telomere length, thereby affecting longevity.

Researches also found that women who use vitamin b12 supplements have longer telomeres than those who don't. Vitamin D3, Zinc , iron, omega-3 fatty acids, and vitamin C and E also influence telomere length. 

Top 12 anti-aging nutrients

  1. Vitamin D
  2. Astaxanthin
  3. Ubiquinol ( CoQ10)
  4.  Fermented foods/probiotics
  5. Krill Oil
  6. Vitamin K2
  7. Magnesium
  8. Polyphenols ( Grapes, Cacao, Green tea)
  9. Folate ( aka Vitamin B9, Or Folic acid)
  10. Vitamin B12
  11. Curcumin ( Turmeric)
  12. Vitamin A

Telomerase as a useful target in cancer fighting

Telomerase was a relevant factor that distinguishes cancer from normal cells. It appeared that its expression and activity is not only limited to cancer cells however, but in this particular cells, the telomerase is much more adundant. Thus, it has become a very-promising target for an anti-cancer therapy. Telomerase is one of the crucial factor to study in oder to improve the cancer diagnostics and therapy or prevention.
