In a revolutionary step toward ending plastic pollution, Japanese scientists have created a new biodegradable plastic that dissolves completely in seawater within hours and enriches soil within just 10 days. Developed by researchers at the RIKEN Center and the University of Tokyo, the material not only breaks down harmlessly—it releases nutrients like phosphorus and nitrogen, boosting soil fertility instead of harming ecosystems. The plastic uses salt-bridge chemistry, combining sodium hexametaphosphate and guanidinium-based monomers to form a structure that’s stable in normal use but degrades rapidly when exposed to marine or soil conditions. This dual-function design means it could be used in agriculture, fishing, or packaging without leaving a harmful trace. With recovery and reuse rates of over 80%, this innovation supports a circular economy and could drastically reduce the world’s reliance on harmful, persistent plastics. #BiodegradablePlastic #SustainableInnovation #OceanCleanup #SoilHealth #PlasticPollutionSolution

Japan is planning one of the world’s most ambitious infrastructure projects—Ocean Spiral, a futuristic underwater city powered by the temperature gradients in ocean water. Designed by Shimizu Corporation, this conceptual city will include a floating sphere above the surface and a spiral structure plunging 4,000 meters into the deep sea, allowing humans to live, work, and even mine ocean-floor resources. Powered by Nature: It will harness Ocean Thermal Energy Conversion (OTEC) technology—an innovative method that generates electricity from the temperature difference between warm surface water and cold deep water. The City’s Promise: Fully self-sustaining energy Food production and seawater desalination Deep-sea exploration and rare metal extraction Disaster-resilient infrastructure If brought to life, Ocean Spiral won’t just be a city—it’ll be a blueprint for sustainable living in an age of climate and land challenges. #OceanSpiral #JapanInnovation #FutureCities #UnderwaterCity

Astronaut's eye view — Mount Fuji from space. Captured by astronaut Soichi Noguchi aboard the International Space Station (ISS), this stunning image shows Japan’s iconic Mount Fuji rising like a beacon through the clouds. At 400+ km above Earth, the ISS offers a rare perspective of our planet’s natural wonders — and this is one of the most breathtaking. #EarthFromSpace #MountFuji #Japan #ISS #SoichiNoguchi #AstronautPhotography
