What Was Wrong with Traditional Epidemic Models? — “Models That Forgot the Past”One of the key indicators describing how fast an infectious disease spreads is the effective reproduction number (R-value), which plays a decisive role in shaping public health policies. However, most widely used epidemic-spread models so far have relied on an unrealistic assumption that all infecte... Name : 전체관리자 Hits : 85 2025.10.30

Brain Blood Flow and Neural ActivityThe brain accounts for only about 2% of body weight, but it consumes more than 20% of the body’s total energy. To meet this high energy demand, blood flow must be precisely regulated every time neural activity occurs. In other words, brain energy metabolism and blood flow changes are intrinsically interconnected, and this relationship forms a... Name : 전체관리자 Hits : 198 2025.10.01

[Science Knowledge Encyclopedia] Experimental Process Uses Sunlight to Extract Hydrogen Fuel from Waste PlasticsMicroplastics that enter the ocean are absorbed by marine organisms and move up the food chain, potentially affecting the human diet. Concerns about health impacts and biodiversity loss linked to this process have been raised internationally. The United Nations Enviro... Name : 전체관리자 Hits : 291 2025.08.21

Pump-Probe Spectroscopy: Revealing Material Properties with LightSpectroscopy is a technique that extracts information about materials by examining their interactions with light. Among its various forms, pump-probe spectroscopy uses short pulses of light to investigate how a material responds or changes, essentially, to observe its properties and reactions. In this method, a "p... Name : 전체관리자 Hits : 522 2025.07.16

Light Dark MatterWhen we gaze up at the night sky, we are met with countless bright stars. The universe is filled with innumerable celestial bodies that spark our curiosity, and the study and observation of these objects—astronomy—is one of humanity’s oldest fields of science. But starting around a century ago, astronomers began to discover phenomena that could not be explained... Name : 전체관리자 Hits : 457 2025.06.23

mRNA therapeutics—best known through the COVID-19 vaccines—have garnered global attention as a breakthrough technology. Yet, until recently, the precise mechanisms by which these synthetic RNAs operate and are regulated inside cells remained unclear. Driven by the question “What happens when an mRNA vaccine enters the body?”, researchers at the Center for RNA Research within th... Name : 전체관리자 Hits : 698 2025.05.27

The Language of the Brain: What Are Brain Waves?Brain waves are rhythmic electrical currents generated when the electrical activity of neurons synchronizes as they communicate with each other. When a neuron is stimulated, it generates an action potential, which is transmitted to other neurons through synapses. During this process, neurotransmitters are released, causing changes...

Autism, a condition more familiar to many thanks to the popular drama Extraordinary Attorney Woo, is characterized by neurological and behavioral symptoms. In the show, the protagonist WOO Young-woo exhibits hypersensitivity to the texture of food, leading her to eat only gimbap. This portrayal reflects real-life cases of autism where individuals often show extreme sensitivity ... Name : 전체관리자 Hits : 904 2025.01.06

Lipid Droplets and DiseasesWhat happens when cells are exposed to excessive energy sources? Similar to how animals store excess nutrients as fat, cells convert surplus energy sources (e.g., glucose, fatty acids) into neutral lipids, storing them in cellular organelles called lipid droplets. Previously, lipid droplets were understood as mere energy reservoirs storing excess neut... Name : 전체관리자 Hits : 951 2024.12.17

Our brain is composed of over 100 billion neurons, which form an even larger number of brain circuits. Technology that can precisely control brain circuits is essential for uncovering the principles behind advanced brain functions such as behavior, cognition, and emotions, as well as for identifying mechanisms of various neurological diseases and developing treatments.
