🌋🌳 TREES CAN WARN US BEFORE A VOLCANO ERUPTS — AND SATELLITES ARE LISTENING! 🛰️🌱

In a fascinating twist of nature-meets-tech, scientists have discovered that trees near volcanoes change their behavior before an eruption.

How? As magma rises underground, it releases carbon dioxide (CO₂) — and surrounding trees absorb this extra gas, becoming noticeably greener.

🌿 These subtle changes in vegetation health are invisible to the naked eye…

📡 But satellites like Sentinel-2 and Landsat can detect them using tools like the Normalized Difference Vegetation Index (NDVI).

🔬 Studies around Mount Etna showed that greener vegetation often correlates with magma movement, providing an early warning sign days or even weeks before an eruption!

🌎 The AVUELO mission also tested this tech in Costa Rica and Panama, proving how remote sensing + ecological signals = smarter, safer volcano monitoring.

🚨 This method doesn’t replace traditional warning systems like seismic sensors, but it offers a powerful new layer of insight, especially in remote or poorly monitored areas.

💡 Nature speaks — and now we can finally listen from space!

In the Paris suburb of Rambouillet, an innovative experiment by French startup Glowee is testing streetlights that use bioluminescence.

These lights contain marine bacteria, Aliivibrio fischeri, in tubes of saltwater which produce a natural, soft blue-green glow when aerated, requiring no electricity.

While this carbon-free system offers benefits like reduced light pollution, making it ideal for parks, its low brightness and the company's reported 2023 bankruptcy filing cast doubt on the future of this living light technology.

Scientists have invented glow-in-the-dark wood made from fungi that could replace streetlights. Imagine parks and streets illuminated naturally at night, cutting down energy consumption and lighting up the planet sustainably! 🌟💡
