Lazy Lifestyle Led To Weaker Bones

The comparatively light bone structure of modern humans compared to ancestor  and other modern primates may be due to the modern abandonment of the constant physical activity that was inherent in the life of early hunter gathers.

The most plausible explanation is that a lack of constant physical activity causes the bone in the head of the femur, the long bone in the thigh, to become thinner and lighter than that found in more mobile populations or modern primates such as chimpanzees, gorillas and orangutans.
The other two possible explanations, that humans and nonhuman primates have different bone structure because of genetics, with humans evolving to a lighter, more gracile structure, Or that the large joint surfaces required for upright, two-legged movement decrease the strain on bone and therefore the development of strong bones, do not appear to be true.

Ryan, working with Colin N. Shaw of the University of Cambridge, UK, looked at the hip joint to determine which of the three possib…

Antimicrobial Metal :- Copper !

Copper and its alloys (brasses, bronzes, copper-nickel-zinc, and others) are natural antimicrobial materials. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century.

Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this process. In several clinical studies, copper has been evaluated for use on touch surfaces, such as door handles, bathroom fixtures, or bed rails, in attempts to curb nosocomial infections. In connection to these new applications of copper, it is important to understand the mechanism of contact killing since it may bear on central issues, such as the possibility of the emergence and spread of resistant organisms, cleaning procedures, and questions of material and object engineering. Recent work has shed light on mechanistic aspects of contact killing.
The antimicrobial properties of copper are still…

Mission :- Educated Bharat

As we know that in Bharat there a lot of children who never get any education. This is because of their background, caste and other problems. I want to education all of them which is impossible yet, but i have an idea to educate them. In Bharat there are a lot of families and a family has a housewife. I know that most them are not educated, but 50% of them are educated. From this 50%, 25% are working or employed anywhere, but 25% are free. So, when they have their spare time (generally afternoon), they should collect 2 or 3 children (who don't have money to educate them) and educate them, just for 1 hour daily. If one housewife educate 3 children, then 5 million housewife educate 15 million of children every hour in India. And in this 15 million of children 50% are girls, so thehousewives of Bharat educating girls too.  At last, it is my request to all the reader please give you 1% percent by sharing my view, because your 1% will be 10% of Bharat's Future . Thank You for reading …
