Bright quantum light emission achieved at room temperature in 2D semiconductors‎

A joint research team led by Professor Park Kyoung-Duck and Associate Director Suh Yung Doug of the Center for Multidimensional Carbon Materials within the Institute for Basic Science (IBS) has succeeded in realizing a high-efficiency quantum light source that emits bright lights even at room temperature. The study is published in the journal Science Advances.

PFAS detected in dolphin milk may pass from mothers to calves‎

Researchers have found that a group of chemicals known as PFAS can be transferred from mother dolphins to their nursing calves, adding to the evidence that these persistent contaminants can be transferred from mothers to offspring during early development.

Earth's tectonic elevator hauls ancient buried microbes back to the seafloor to revive and spread‎

In subduction zones, the sites of the world's largest earthquakes, tectonic activity may generate a "pump" that transports long-buried subseafloor microbes back toward the seafloor, according to research presented at the 2026 SSA Annual Meeting.

Global N2Onet aims to cut farm nitrous oxide emissions with shared data‎

Nitrogen (N) fertilizer supports global agriculture, but its use and overuse drive emissions of nitrous oxide (N2O), a potent and long-lived trace gas. Incomplete understanding of N2O flux drivers makes it difficult to make spatiotemporal emissions predictions and evaluate management strategies for emissions reductions. N2O experts evaluated current sources of uncertainty and propose an initiative for accelerating advances in N2O measurement, analysis, and mitigation.

Rivers are driving a hidden permafrost meltdown, with thaw progressing 15% faster than expected‎

Thawing permafrost buried underneath rivers may be accelerating permafrost degradation faster than previously estimated in these inundated regions, according to new research shared at the 2026 SSA Annual Meeting.

Taiwan landslide's hidden motion comes into focus as fiber optics track deep slip‎

Placed within a borehole drilled deep through the layers of a landslide, a fiber optic cable captured tiny, periodic stick-slip events that offer a unique glimpse at the complex movements within the landslide's shear zone.

Wildfires used to 'go to sleep' at night. Climate change is turning them into prime burning hours‎

Burning time for North American wildfires is going into overtime. Flames are lasting later into the night and starting earlier in the morning because human-caused climate change is extending the hotter and drier conditions that feed fires, a new study found.
