Leonardo da Vinci’s Aerial Screw: A 500-Year-Old Idea Takes Flight Today

The Renaissance Blueprint That Wouldn’t Work—Until Now For centuries, Leonardo da Vinci’s “aerial screw” was a symbol of genius ahead of its time — brilliant, but doomed to fail. The sketch, drawn around 1480, showed a spiral rotor meant to lift a platform into the air. It looked like a corkscrew made of linen, reed,…

Artificial Intelligence: Between Promise and Peril

AI, Engineering, Humanity, Trending

The world once again stands at the edge of a great shift. Today its name is artificial intelligence. It promises to solve problems humanity has struggled with for centuries: curing diseases, tackling climate change, making transportation safer, and distributing resources more fairly. But at the same time, it creates new risks: global systems of control,…

The Future of Living Light: Can Bioluminescence Replace Electricity?

Biology, Engineering, Environment, Genetics, Humanity, Plants, Popular, Science, Trending

When we flip a switch and flood a room with light, it feels almost magical. Yet behind this everyday miracle lies a hidden infrastructure: vast power grids, burning fuels, nuclear reactors, and fragile networks that stretch across our cities. But what if light could be alive? What if instead of wires and bulbs, we invited…

In a groundbreaking development for internet security, researchers at Leibniz University Hannover have unveiled a new quantum encryption technique that promises to make online communications unbreakable. This innovative approach leverages the power of light and color to enhance quantum key distribution, a crucial component for securing data in the face of emerging quantum computing threats.…

News: How NASA’s MARVL Project Could Revolutionize Travel to Mars

Engineering, News, Science

Can we make the journey to Mars faster, safer, and more energy-efficient? Space engineers have been grappling with this question for decades. Now, thanks to NASA’s latest research, we might be closer than ever to turning that dream into reality. The key? A project called MARVL — a concept that could fundamentally change how we…

How fusion works?

Engineering, Fusion, Physics, Popular

The energy of a nucleus can be tapped in two ways: by splitting large nuclei into smaller ones (fission) or by combining small nuclei into larger ones (fusion). The first method yields atomic or nuclear (fission) energy, while the second provides fusion energy, which is essentially stellar power. This is the way the sun and…

Robot worms for building tunnels

AI, Engineering, Popular

Tunnels have always been an important part of infrastructure, and although a significant number of tunnels have been built in many countries over the past few decades, traditional construction methods have often been limited. For example, the Channel Tunnel, which connects France and the United Kingdom, took over 15 years to complete and cost more…
