How is memory formed and maintained? We explore the principles of how memory is formed and maintained by synaptic connections of neurons and long-term potentiation. Many studies in neuroscience explain memory formation as “long-term potentiation”. According to this theory, nerve cells in the brain share information by transmitting electrical and chemical signals across...

How do antibiotics kill bacteria and what role do they play in the fight against resistant bacteria?
Antibiotics interfere with the survival mechanisms of bacteria, exerting a powerful antibacterial effect, but they have faced new challenges with the emergence of resistant bacteria. We explore the working principles of antibiotics and ways to overcome resistance. In China, people have used moldy tofu to treat rashes and boils for 2,500 years, and in Korea, people have used soybean paste...
How did the invention of the tuning fork affect music?
The tuning fork was invented by John Shore in 1711 and helped improve the accuracy of tuning musical instruments. It later had a significant impact on the establishment of the standard frequency (440 Hz) and the study of acoustics. A tuning fork is made by bending a square metal bar of uniform thickness into a U-shape and welding a metal rod firmly to the bottom. This device produces a...
How do dancers achieve artistic communication with the audience and change their emotions and perceptions?
Dance is an outward art in which dancers convey their enlightenment and inspiration to the audience, expressing emotions through movement and allowing the audience to gain new experiences and perceptions through this process. Like other art forms, dance is an outward-looking activity in that it expects a response. In other words, dancers create their works with the intention of...
Why do humans perceive different loudness of sounds depending on frequency and sound pressure?
Sound pressure refers to the physical magnitude, and loudness refers to the magnitude perceived by humans. The interaction between frequency and sound pressure is related to auditory characteristics, and understanding this will help you create a better acoustic environment. Physically, sound has sound pressure and frequency. Sound pressure is the pressure per unit area of a sound, and it...
What is the best way to prevent free-riding in group work?
How can we prevent free-riding in group assignments and ensure that everyone participates fairly? We are looking for effective ways to do group work. In high school, when group assignments are given, it is common for the students who study well to complete all the assignments on their own, and for the other members of the group to read the assignments briefly before handing them in. If you...
How does archaeology reconstruct life in the past?
Archaeology reconstructs human life in the past through artifacts and ruins. It studies ancient lifestyles from a variety of perspectives, including evolutionary and sociocultural interpretations. Archaeologists use this data to reconstruct the lives of people in the past by applying theories from various fields. Archaeological research is essential for understanding human evolution and...
What climatic and topographical influences did the Himalayas have on the formation of the desert?
The Himalayas influenced the climate and topography, leading to the formation of the desert. This article examines the process and geological changes. Are all deserts barren lands where hot, fierce sandstorms blow? While there are tropical deserts, there are also temperate deserts, such as those in the highlands or interior of continents, where summers are hot but winters are cold. Deserts...
