Advances in biotechnology allow us to create organisms with previously unrecognized properties through genetic manipulation, revolutionizing medicine, agriculture, and many other fields. However, these advances raise serious ethical issues, including the potential for human extinction, and require careful social debate and legal standards.   Humans have accomplished a lot, and biotechnology...

I had always wanted to play classical guitar since I was in high school, so I joined the Arpeggio club in college and started practicing, but I struggled to prepare for recitals due to my lack of consistency and responsibility. This made me realize that a responsible attitude and consistent effort are very important not only in college, but also in my future life.   When I was in high...

This article discusses the importance of both natural talent and acquired effort. It uses various examples to show that hard work alone cannot beat genius, and concludes that it’s important to live life to the best of your ability given your talents and circumstances.   Since ancient times, people have debated whether it is nature or nurture that determines human behavior. In the...

  In The Selfish Gene, Richard Dawkins denies handicap theory through natural selection, but handicap theory can be seen as a valid way to favor stronger genes in the process of sexual selection, as males with handicaps can be selected for by the environment.   Introduction In The Selfish Gene, Richard Dawkins argues for a theory of natural selection in which genes are the immutable...

Renewable energy research is underway to solve the problem of carbon dioxide emissions from fossil fuel power generation, one of which is nuclear fusion energy generated in tokamaks using superconductors. Superconductors have zero resistance at extremely low temperatures, allowing strong electricity to flow through them, which is essential for creating artificial suns. Future advances in...

Synthetic and fluorescent dyes play an important role in the textile industry, as well as in the medical, computer, and mechanical industries. Fluorescent dyes, in particular, are used in genetic research, dentistry, and cancer treatment due to their ability to emit bright light, and are environmentally friendly and recyclable, contributing to sustainability.   The development of chemistry...

Microwaves heat food quickly and efficiently using microwave technology, which was discovered by accident during World War II. Microwaves heat food by resonating with water molecules, causing them to spin and generate heat. This heats only the food, not the bowl or walls inside the microwave.   “30 seconds in the microwave”. This is a common advertising phrase for many instant...

Stem cells and induced pluripotent stem cells (iPS cells) are playing an important role in regenerative medicine and the development of personalized therapies due to their ability to differentiate into a variety of cells. With ethical and supply issues addressed, iPS cell technology is revolutionizing tissue engineering, drug discovery, regenerative medicine, and more, opening up new...

Nuclear power plants are highly energy efficient, but they are also highly risky due to corruption and safety issues. In addition to nuclear power, we need to explore and research various alternative energy sources for safe energy use.   This past summer was unusually hot. It was even hotter because there was nowhere to escape the heat. You couldn’t go into a bank, department store, or...

Discusses the influence of heredity and environment on human behavior, emphasizing that nature and nurture are complementary, not opposing, forces. Explain that genes change through interaction with the environment, and that human behavior is the result of a combination of these two factors.   Philosophers and scientists have long wondered where human behavior comes from. The debate over...
