What was the young Sun really like? An international team including Prof. Jongchul Chae at SNU has captured a powerful coronal mass ejection from EK Draconis — a star that’s basically a “time machine” version of our Sun. For the first time, they spotted both cool and super-hot

Prof. Seongjun Park’s team at SNU has developed all-hydrogel neural fibers that can record, stimulate, and deliver drugs — all while moving naturally with brain tissue. By replacing metals and plastics with soft, biocompatible hydrogels, the device minimizes inflammation and

Our AI-powered platform helps you deliver digital innovation faster and with less risk by providing a fundamentally better approach to test automation.

“Click chemistry,” a highly selective and efficient reaction that earned the 2022 Nobel Prize, has now been realized using a protein-based catalyst developed by Prof. Woon Ju Song’s team. Their artificial enzyme broadens the horizon for designing biocompatible metal catalysts.

What makes some brains age faster than others? Prof. Taesung Park’s team analyzed proteins in the cerebrospinal fluid of nearly 1,000 healthy adults to uncover how aging, genes, and even biological sex shape early brain changes linked to Alzheimer’s. Published in Nature Aging:

When the air gets dirty, your medicine might still have your back. Prof. Sang Min Park’s team at SNU found that older adults who regularly took cholesterol-lowering drugs (statins) were less likely to develop heart disease—even under high levels of fine dust. Published in The

“Our goal is to train the immune system to neutralize fentanyl before it can cause harm,” says @collingage_ , Founder and CEO of @ARMRsciences The company is focused on protecting adolescents, first responders, and military personnel while preparing for a pre-IPO launch under

All-solid-state batteries — the “dream battery” for safer and longer-lasting energy storage. ⚡ Prof. Sung-kyun Jung’s team at SNU discovered how tiny chemical reactions at the cathode–electrolyte interface lead to performance loss—and found a way to keep it stable for longer

How do lithium ions really move inside a battery?💡 Prof. Jongwoo Lim’s team found that it’s not just about chemistry — tiny mechanical strains in the material also guide how lithium travels. Using powerful X-ray microscopes, they watched ions move in real time and saw them take

Okara—the soybean pulp left behind from making tofu or soy milk—is full of protein and fiber, yet most of it gets tossed out. Prof. Doman Kim’s team at SNU found a clever, eco-friendly way to ferment and transform this by-product into a nutritious, high-value ingredient—turning

Winter roads may be safer with deicers, but they can quietly harm the very trees that keep our cities livable.🌳❄ Prof. Hyun Seok Kim’s team revealed how both conventional and so-called eco-friendly deicers pose long-term stress to urban trees—underscoring the need for smarter

A quick reminder 🙂

South Korea’s COVID-19 relief payments did more than boost spending—they slowed the virus too. 📉💳 Prof. Hyojung Lee’s team found that in Seoul, credit card use jumped 5%, while local-use rules cut infection spread by about 17%. A rare win-win: stronger economy, safer

Ever wonder how the brain remembers familiar faces? Prof. Yong-Seok Lee’s lab at SNU found that a circuit from the prefrontal cortex to the nucleus accumbens stores social memory—capturing both identity and a sense of “familiarity,” with the hippocampus helping to lock it in.

Stem cell transplants can beat leukemia, but many patients face a tough side effect—acute graft-versus-host disease (GVHD). Prof. Kyung-Rok Yu’s team came up with a nano–cell therapy that helps the immune system stay in balance, easing GVHD in models and pointing to safer

Autoimmune diseases, metabolic disorders, even cancer—all share a common culprit: uncontrolled inflammation. Prof. Rajendra Karki’s team has uncovered a next-gen compound that blocks the body’s overreaction—even in cases where older drugs no longer work. By quieting immune cells

Neurons stay healthy by recycling their worn-out parts—but how exactly do they pull it off? Prof. Sunghoe Chang’s team uncovered a crucial protein that acts as a helper in this cleanup process. Without it, neurons fail to clear away waste, leading to damage and cell death. This

Billions of protein sequences, now supercharged. Prof. Martin Steinegger’s team, with Mainz University and NVIDIA, created MMseqs2-GPU—a tool that spots similarities between proteins up to 20× faster and 71× cheaper than before, clearing a big hurdle for AI like AlphaFold and

Bacteria have a built-in “checkpoint” to make sure faulty messages don’t slip through when making proteins. Prof. Nam Ki Lee and Prof. Sang Woo Seo’s team found that this quality control happens right at the start of gene expression—much earlier than scientists expected. The

At the supermarket, you might toss apples into your cart without thinking—yet other times, you pause and reconsider. 🍎🛒 These two modes of behavior—habit and flexibility—are split in the primate brain along a front–back axis, as shown by Prof. Hyoung F. Kim’s team. The

Proteins don’t just float around randomly—they work in very specific spots inside our cells. To find out exactly where they sit in one of the trickiest places, the mitochondrion, Prof. Hyun-Woo Rhee and Prof. Jong-Seo Kim’s team, together with UNIST, created a new method that can

A new way to fight the flu may come from harnessing our own immune system. Prof. Sung-Gyoo Park and Prof. Yunpyo Kang’s team has discovered how to guide T cells—the body’s immune defenders—to grow and respond more effectively. In flu models, boosting this immune memory helped

What if your mind had a shape—would it be a line, a square, or a pyramid? Prof. Hyoung F. Kim’s team has shown, for the first time, how the primate brain forms a “shape of mind” right before making a decision. By combining what we see and what we touch, neurons in the putamen
