One example of how applied science has had a direct effect on daily life is the presence of vaccines. Vaccines to prevent diseas
Mashutka [201]

Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.

Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.

While this can seem beneficial because plants use carbon dioxide in photosynthesis, elevated levels of carbon dioxide actually inhibit photosynthetic mechanisms (Xu, 2015).
