The undo button for 3D printing has arrived—and it’s pure sci-fi come true
Traditional 3D printing works in only one direction: you add material layer by layer, and once something is printed, it stays that way.
If a...
Scientists build millimeter-scale robots that move faster than ever before
In the 1980s, when micro-electro-mechanical systems (MEMS) were first invented, engineers imagined a future where robots could be shrunk to microscopic sizes.
Smaller robots promised...
Spray 3D printing could reinvent how we build earthquake-proof buildings
Concrete 3D printing is revolutionizing the building industry by cutting costs and construction time.
However, most current systems use an extrusion-based method, laying down concrete...
New material could make car speakers sound perfect for every passenger
Anyone who has turned up the music in a car knows that sound doesn’t always reach everyone the same way.
The driver might enjoy perfect...
Bacterial spores could create self-healing, sustainable building materials
Scientists are bringing the concept of “living materials” one step closer to reality by using one of nature’s toughest survivors—bacterial spores.
A team of researchers,...
Cooling paint that pulls water from the air could transform cities and farms
Scientists in Australia have developed a remarkable new paint-like coating that can keep buildings cool and collect fresh water straight from the air—without using...
New camera lens can keep everything in focus— from inches away to infinity
Imagine taking a photo where every single detail—from the flower right in front of your lens to the mountains far in the distance—is crystal...
Next-generation wound care uses light and electricity to help the body heal itself
Scientists at National Taiwan University have found a promising new way to help chronic wounds heal faster and with fewer scars—by guiding the body’s...
