NASA scientists have reported that China’s colossal Three Gorges Dam—the largest hydroelectric dam in the world—has such immense mass and water displacement that it can alter Earth’s rotation ever so slightly. According to the agency, the redistribution of 39 trillion kilograms of water has shifted Earth’s moment of inertia, potentially lengthening the day by 0.06 microseconds.

This effect, while incredibly small and imperceptible in daily life, highlights the profound influence human engineering can have on planetary-scale physics. The dam has also caused measurable changes in Earth's gravity field, according to satellite observations.

But it’s not just time that’s affected—geologists warn that the dam’s enormous reservoir has triggered seismic activity, landslides, and altered ecosystems. Environmental experts have long debated whether the benefits of energy generation and flood control outweigh the ecological and geological consequences.

This is a stark reminder that when humanity builds on a massive scale, Earth itself feels the shift.

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.
