Re: What forces have shaped humanity most?
Disease and the various ways that we have dealt with disease has probably had the biggest impact on humanity. Until humanity started figuring methods of preventing and reducing the impact of disease, the world's population (for better or worse) would be nowhere near the present levels. We have developed a myriad of responses to preventing and treating disease ranging from things as simple as bathing on a regular basis to very complex technologies and surgical procedures. Without the medical procedures and technologies that have been developed over the ages, the human population would, most likely, be much, much less than it is today. Cities as we know them couldn't exist without some methods of treating and preventing disease.
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
It turns out the human scalp has an olfactory receptor that seems to play a crucial role in regulating hair follicle growth and death.
- Scientists treated scalp tissue with a chemical that mimics the odor of sandalwood.
- This chemical bound to an olfactory receptor in the scalp and stimulated hair growth.
- The treatment could soon be available to the public.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
