Famine in North Korea Redux? [PDF]
In the 1990s, 600,000 to 1 million North Koreans, or about 3 to 5 percent of the precrisis population, perished in one of the worst famines of the 20th century.North Korea is once again poised on the brink of famine. Although the renewed provision of aid

Impact of Deforestation on Agro-Environmental Variables in Cropland, North Korea
, 2017 Deforestation in North Korea is becoming the epitome of the environmental change occurring in the Korean Peninsula. This study estimates the agro-environmental variables of North Korea’s croplands and analyzes the impact of deforestation using the GEPIC (

Advanced Materials, EarlyView.This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Chemically Doped Conductive Polymers for Wearable Health Monitoring
Advanced Materials Technologies, EarlyView.Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

North Korea on the Precipice of Famine [PDF]
North Korea is on the brink of famine. The aggregate food picture appears worse than at any time since the famine of the 1990s. The margin of error between required grain and available supply is now less than 100,000 metric tons.

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser
Advanced Science, EarlyView.An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling
