How is memory formed and sustained over time? This explores the principles by which memory is created and maintained through synaptic connections between neurons and the process of long-term potentiation. Many studies in neuroscience explain memory formation through ‘long-term potentiation’. According to this theory, neurons in the brain form synaptic connections by transmitting electrical...
Nitroglycerin is widely known as an explosive, but the fact that this substance can also be used as a treatment for angina explains an intriguing scientific principle, including an irony connected to Nobel’s life. ‘Nitroglycerin’ is a substance with the molecular formula C3H5(NO3)3, ranking among the most powerful explosives known to date. Liquid nitroglycerin possesses such power...

In this blog post, we explore the origins of the myth that we only use 10% of our brain and examine the scientific facts to determine its truth in an easy and interesting way. “Most people use only 5 to 6% of their brain. But I use 7%.” This is often attributed to the famous scientist Albert Einstein, but in fact, he never said this during his lifetime. Nevertheless, it has become a phrase...
This blog post discusses whether a brain-dead pregnant woman should be forcibly used like an incubator for the fetus’s life, and how we should view the issues of dignified death and abortion in such a situation. Long ago, during my university days, I took a course called ‘Bioethics’. This course aimed to address various bioethical issues arising in modern society. After discussing...
This blog post delves deeply into the boundary between humans and machines, and the criteria for ‘humanity’. Led by deep learning, artificial intelligence is advancing day by day. Deep learning, which derives answers using statistical techniques, falls far short of strong artificial intelligence—AI possessing true intelligence. However, devices utilizing deep learning can significantly...
This blog post explores the changes and possibilities AI will bring to agriculture, focusing on real-world application cases. The Future of Artificial Intelligence After AlphaGo Back in March 2016, the artificial intelligence (AI) program AlphaGo defeated Lee Sedol in a Go match with a score of 4 wins and 1 loss.
