U.S. Scientists Develop Metal So Light It Can Float on a Dandelion!

In a stunning feat of materials engineering, researchers in the U.S. have created microlattice metal, the lightest structural metal ever made—so airy it’s 99.99% empty space and 100 times lighter than Styrofoam.

How it works:
The metal is structured like human bones—hollow tubes in a lattice pattern that provide strength without bulk. Despite its fragile appearance, it’s remarkably resilient, bouncing back after compression and bearing weight without crumpling.

Why it matters:
NASA and aerospace industries are testing this material for:

- Satellites & spacecraft

- Impact-absorbing structures

- Fuel-saving components

By drastically reducing weight, this innovation could cut fuel consumption, emissions, and shipping costs across aviation, automotive, and even wearable tech sectors.

It’s a breakthrough not just in design, but in how we think about the physical limits of materials.

A new hydrogen-powered car is making headlines for delivering what electric vehicles still struggle to match: ultra-fast refueling and long-distance range. The vehicle claims to fully refuel in just 5 seconds and can travel up to 1,500 kilometers—a potential game-changer in clean transportation.

Unlike battery-electric cars that require hours of charging, this hydrogen fuel cell car emits only water vapor, making it one of the most eco-friendly zero-emission solutions available.

Hydrogen vehicles convert hydrogen into electricity using a fuel cell, offering high energy density and minimal downtime.

In contrast to battery-electric vehicles, hydrogen fuel cells are:

- Faster to refuel

- Capable of longer continuous operation

- Lighter over long distances due to lower storage weight

With fuel cell buses already deployed in cities like Beijing, Tokyo, and Seoul, this car hints at a hydrogen-powered future beyond public transit—one where consumers don’t sacrifice speed or convenience for sustainability.

A breakthrough material called Superwood, developed by researchers at the University of Maryland, is set to enter commercial production in 2025. This engineered timber is up to 50 times stronger than regular wood and even rivals steel and carbon fiber in strength—yet it's lighter, cheaper, and sustainably sourced.

Superwood is created by removing lignin and hemicellulose from natural wood, then hot-pressing it to align the cellulose nanofibers into a dense, ultra-tough structure. The result? A bio-based material that’s resistant to fire, rot, pests, and harsh weather—ideal for construction, furniture, transportation, and even armor plating. Maryland startup InventWood is now scaling up its production, promising a future where buildings and vehicles may be built with eco-friendly timber tougher than metal.

Scientists have developed a remarkable new material named Proteus that has the ability to stop bullets while being ultra-thin and lightweight.

This material hardens instantly upon impact, behaving in a way similar to diamond, making it extremely difficult to penetrate.

The innovation draws inspiration from natural structures like grapefruit peels and abalone shells, which are known for their unique ability to absorb and disperse energy effectively.

Proteus is made by embedding hard ceramic spheres within a flexible aluminum structure. When a bullet or drill strikes the material, it reacts dynamically.

The ceramic particles inside begin to vibrate at high frequencies, which blunts the projectile and spreads the force across the structure, making it nearly impenetrable. This combination of flexibility and extreme toughness is unlike anything seen in conventional body armor materials.

Researchers from the University of Surrey and the Leibniz Institute conducted extensive studies on Proteus and confirmed its unique properties.

It falls under a category of materials known as non-Newtonian substances, meaning it behaves differently under varying types of force. Under sudden, high-speed impacts, it transitions from soft and flexible to extremely hard, stopping bullets and tools alike.

This innovation has wide-ranging potential applications. It could revolutionize body armor for military and law enforcement, allowing for lighter gear that still offers full protection.

It could also be used in protective casings for vehicles, secure storage containers, and bullet-resistant building materials. With Proteus, the future of protective technology looks thinner, stronger, and smarter.
