Imagine a world where countries aren’t just linked by data cables—but by high-speed underwater trains.
That’s the vision behind a $1 trillion megaproject to connect Dubai and Mumbai via a 2,000 km submerged rail tunnel across the Arabian Sea.

The proposed line could supercharge tourism, trade, and freshwater supply to the UAE—while presenting extreme engineering and geopolitical challenges. If it becomes reality, it could be one of the boldest infrastructure moves of the 21st century.

Would you ride beneath the ocean?
Here’s how this could change everything:

Fireflies, known for their magical glow and ecological significance, are facing a dramatic global decline, and scientists warn that we could be the last generation to see them in the wild.

This alarming trend is driven by a combination of light pollution, which interferes with their mating signals; habitat destruction due to urban development and deforestation; pesticide use, which kills both larvae and their prey; and climate change, which disrupts their life cycles and breeding patterns.

Fireflies are especially vulnerable because many species have highly specific environmental needs—such as moist habitats and darkness—which are being rapidly erased by modern human activity.

The decline of fireflies is not just a nostalgic loss but also an ecological warning.

These insects are considered bioindicators, meaning their disappearance signals broader damage to ecosystems, including wetlands and forests. However, conservationists emphasize that extinction is not inevitable.

Simple steps—like reducing outdoor lighting, preserving natural habitats, avoiding chemicals, and participating in citizen science projects such as Firefly Watch—can help protect remaining populations.

The fate of fireflies rests in our hands, and acting now could ensure future generations still witness their light in the darkness.

Germany has taken a bold step toward climate-proof cities with the invention of ultra-absorbent "smart roads"—engineered surfaces that soak up up to 4 tons of rainwater per minute. Instead of pooling and flooding, water is swiftly absorbed and redirected through porous layers beneath the surface.

How it works:
These permeable roads use a specialized concrete mix and layered drainage systems to channel water underground—protecting road surfaces, reducing aquaplaning risks, and preventing costly stormwater damage.

This innovation is a response to Europe’s rising flood risks caused by climate change and extreme weather. The tech not only improves urban safety and road longevity, but also eases pressure on sewer systems.

Imagine rain vanishing the second it touches the ground—Germany is paving the way, literally.

Ever wondered where humanity and our robotic explorers have actually landed on the Moon? This map shows the historic touchdown sites of some of the most iconic lunar missions — from the legendary Apollo landings, to robotic Surveyor probes, Soviet Luna landers, and China’s recent Chang’e missions.

The U.S. Apollo program (1969–1972) sent 12 astronauts to walk on the Moon — a feat still unmatched.
NASA’s Surveyor missions helped test landing tech before the Apollo era.
The Soviet Union’s Luna landers were the first to impact, orbit, and soft-land on the Moon.
China made history with Chang’e-3 and Chang’e-4 — the first to land on the Moon's far side!

Each dot on this Moon map represents years of planning, incredible science, and the dream of exploring beyond Earth.

A new study has shown that global mercury levels in rivers have increased two- to three-fold since around 1850, the onset of the Industrial Revolution.

Mercury, particularly in its organic form (methylmercury), is a powerful neurotoxin that primarily threatens human health through contaminated fish consumption.

Rivers, which play a vital role in providing drinking water and food and in transporting nutrients to the ocean, have become significant conduits for mercury pollution.

Using a global model, researchers estimated that rivers carried about 390 megagrams (metric tons) of mercury to the oceans annually in preindustrial times.

This baseline serves as a critical reference point to understand human-induced changes. In present-day conditions, that number has more than doubled, largely due to mercury emissions from coal burning, gold mining, industrial processes, and deforestation.

The study also emphasizes that mercury concentrations in rivers respond quickly to human activities, making them useful indicators for tracking pollution control measures.

By understanding these patterns and comparing them over time, policymakers can better design and evaluate environmental regulations aimed at reducing mercury pollution.

These findings align with existing research by institutions like the UNEP Global Mercury Assessment and efforts under the Minamata Convention on Mercury, which aim to reduce global mercury emissions.

However, this study adds value by quantifying the historical and present-day riverine mercury flux, offering a global baseline for restoration and policy goals.
