This article examines whether animal testing is ethically problematic and discusses the justification for sacrificing other life for human survival and development. Exploring the relationship between humans and animals, it argues that animal testing itself is not ethically problematic, but that ethical standards should be strengthened through the 3Rs principle (replace, refine, and reduce) to...

In movies such as Iron Man and The Terminator, artificial intelligence is often depicted as either carrying out human commands or as a threat to humanity. Real-world A.I. is still weak and doesn’t fully embody autonomous learning and judgment, but the debate continues about the implications for humanity if stronger A.I. is possible through the development of artificial brains.   Iron...

Genetic engineering is useful for treating and preventing genetic diseases, but if it becomes widespread, it could threaten humanity’s right to equality and diversity. To prevent this, we need to limit the scope of genetic modification and strengthen social morality.   Our right to be different must be protected. I am different from the person in the room in front of me, and I am...

There is a long-standing debate about the role of nature and nurture in shaping human beings. Initially, it was believed that genes determined our bodies and even our personalities, but as research has progressed, epigenetics has come to the forefront, suggesting that environmental influences can alter gene expression. As a result, the idea that genes and the environment interact to shape human...

  Humans have shaped and developed civilization through cognitive genes, a biological trait that gives us the ability to think better than other animals, and through memes. Memes are cultural elements that replicate and evolve in human societies, creating concepts like capitalism and driving civilization forward. Through this, human civilization has evolved to develop various ideologies and...

As AI technology advances, there is a need for strong AI with self-awareness, rather than weak AI that performs simple tasks. Strong AI is an AI that has a sense of self, reason, and emotion, and should be able to understand and judge situations like a human. This requires technological advances in developing complex reasoning through machine learning, genetic algorithms, and creating new models...

As programming has become more popular, different coding styles have emerged, creating readability issues. Adopting a standard coding style can have a positive effect on maintenance, collaboration, and programming education, and can contribute to code comprehension in open source and educational settings.   Recent advances in IT technology have increased interest in the IT field, and many...

In group activities and social life, it’s sometimes tempting to ignore norms for personal gain. However, playing by the rules and working together is necessary for the success and better outcome of the community, which in turn benefits the individual in the long run.   Every moment of our lives, we are faced with choices: sometimes we choose what’s best for us, regardless of...

Nuclear power plants are designed to keep the concentration of uranium tightly controlled to prevent a nuclear bomb-like explosion. In the Fukushima and Chernobyl accidents, where radioactive material leaked due to a damaged cooling system, safeguards have been strengthened in recent years. However, in addition to technical safety, transparent operations and the prevention of corruption are...

Sweaty clothes during intense exercise can lower your body temperature and reduce your performance. This increases the risk of hypothermia, especially in cold environments, which emphasizes the need for technical fabrics that wick moisture away quickly. For example, Coolmax fibers made from polyester wick sweat away from the skin through capillary action to keep you cool, and are also cold and...
