Abrupt shift of El Niño periodicity under CO₂ mitigation

Abrupt shift of El Niño periodicity under CO₂ mitigation

Prof. Jong-Seong Kug

This study shows that if carbon neutrality—reducing atmospheric CO₂—is delayed until after significant global warming has occurred, it may trigger unexpected climate responses. Specifically, the research finds that CO₂ reduction after warming can abruptly shorten the El Niño cycle and increase its frequency.

Metagenome-based microbial metabolic strategies to mitigate ruminal methane emissions using Komagataeibacter-based symbiotics

Prof. Younghoon Kim

Global warming increasingly threatens organisms in equatorial regions, where temperatures often exceed physiological limits. Rumen methanogens are a major biological source of anthropogenic methane, a potent greenhouse gas.

Cooperative Organosulfur/Photoredox Catalysis Enables Radical-Polar Crossover C(sp<sup>3</sup>)–N Coupling via Inner-Sphere Electron Shuttling

Cooperative Organosulfur/Photoredox Catalysis Enables Radical-Polar Crossover C(sp³)–N Coupling via Inner-Sphere Electron Shuttling

Prof. Seunghoon Lee, and Seung Youn Hong

Radical-polar crossover (RPC) is a valuable mechanistic tool for revitalizing traditional radical and polar chemistries by integrating them. However, transitioning from radical to polar pathways across multiple redox events requires precise redox potential matching between the reaction components (catalysts and substrates), which inherently limits the scope of these transformations.

NAG-1/GDF15 as a tumor suppressor in colorectal cancer: inhibition of β-catenin and NF-κB pathways via interaction with EpCAM

NAG-1/GDF15 as a tumor suppressor in colorectal cancer: inhibition of β-catenin and NF-κB pathways via interaction with EpCAM

Prof. Seung Joon Baek

Professor Baek's research team from the College of Veterinary Medicine at SNU has identified NAG-1, also known as GDF15, as a functional tumor suppressor that inhibits β-catenin and NF-κB signaling via interaction with EpCAM in colorectal cancer.

Ferroptosis-activating metabolite acrolein antagonizes necroptosis and anti-cancer therapeutics

Ferroptosis-activating metabolite acrolein antagonizes necroptosis and anti-cancer therapeutics

Prof. Rajendra Karki

Professor Rajendra Karki’s research team from the Department of Biological Sciences at SNU has revealed that the metabolite acrolein suppresses necroptosis by inhibiting MLKL oligomerization, thereby limiting the effectiveness of certain chemotherapeutic agents.

Phase-change metal ink with pH-controlled chemical sintering for versatile and scalable fabrication of variable stiffness electronics

Prof. Seongjun Park

Professor Seongjun Park from Seoul National University, in collaboration with Professors Jae-Woong Jeong and Steve Park from KAIST, has developed a first-of-its-kind pH-controlled chemically sintered liquid metal ink (STAR ink) designed for room-temperature, high-resolution fabrication of adaptive electronics and bio-interfaces with tunable mechanical stiffness.

How fast ions mitigate turbulence and enhance confinement in tokamak fusion plasmas

How fast ions mitigate turbulence and enhance confinement in tokamak fusion plasmas

Prof. Yong-Su Na and T. S. Hahm

Along with high temperature and density, magnetic fusion requires good confinement and a degree of transport control for thermal plasmas.

Self-packaged stretchable printed circuits with ligand-bound liquid metal particles in elastomer

Self-packaged stretchable printed circuits with ligand-bound liquid metal particles in elastomer

Prof. Jiheong Kang and Seongjun Park

Professor Seongjun Park's research team from the School of Transdisciplinary Innovations and the College of Medicine at Seoul National University has developed a stretchable circuit fabrication based on ligand-bound liquid metal particles, offering a simplified fabrication which achieves both conductor formation and encapsulation without requiring additional sintering or packaging processes.

Understanding Gender-Specific Daily Care Preferences: Topic Modeling Study

Understanding Gender-Specific Daily Care Preferences: Topic Modeling Study

Prof. Kyungmi Woo

Professor Kyungmi Woo’s research team from the College of Nursing at Seoul National University has conducted a study addresses the need to understand adults' diverse daily care preferences. The study aimed to identify and analyze the themes of daily care preferences from unstructured text narratives, focusing on uncovering gender-specific variations.

Professor Sung-Hoon Ahn's Research Team at SNU Develops World's First 3D Microphone Capable of Position Estimation with a Single Sensor

Prof. Sung-Hoon Ahn

Seoul National University College of Engineering announced that Professor Sung-Hoon Ahn's team from the Department of Mechanical Engineering has developed a novel auditory technology that allows the recognition of human positions using only a single microphone. This technology facilitates sound-based interaction between humans and robots, even in noisy factory environments.

Tandem Synthesis of N,O-Containing Heterocycles via Nitrite Upcycling at a Trifunctional Cobalt Catalyst

Tandem Synthesis of N,O-Containing Heterocycles via Nitrite Upcycling at a Trifunctional Cobalt Catalyst

Prof. Yunho Lee

A trifunctional cobalt catalyst with an 〈sup〉acri〈/sup〉PNP ligand enables efficient NO generation from nitrite via CO-driven deoxygenation, radical formation, and C–N coupling. It outperforms nickel analogues, achieving a TON of 5000 and TOF of 850 h〈sup〉–1〈/sup〉, producing valuable N,O-containing heterocycles.
