3D-printed concrete structures are claimed to be faster and cheaper to build than their traditional counterparts, but they're not always as strong. That problem may soon be solved by adding a pinch of graphene oxide, which could also be used to detect cracks.

The microscopic structure of the feathers of the eastern bluebird, a type of North American thrush, has inspired the creation of a simple-to-produce, scalable and robust novel synthetic material that could be used in batteries and water filters.

Prepare for a radical acceleration in technological development. A Google Deepmind AI has achieved "an order-of-magnitude expansion in stable materials known to humanity," finding about 800 years' worth of new materials with revolutionary potential.

Hospitals are meant to heal people, but patients often pick up superbugs during their stay. Scientists have now developed long-lasting antimicrobial coatings for textiles that could allow hospital curtains to quickly kill viruses and bacteria.

Concrete may seem strong, but it can be surprisingly vulnerable to the elements. Now researchers at Drexel University have demonstrated a type of self-healing concrete embedded with “BioFibers” that use bacteria to patch up cracks as they form.

It’s a basic fact that temperatures drop at night, damaging crops, equipment and infrastructure. Scientists have created a new film that selectively absorbs and reflects different wavelengths of infrared light to efficiently keep objects warm.

Scientists have demonstrated a new ultra-white ceramic material that drastically cools buildings, with record-high sunlight and heat reflectivity. The beetle-inspired material gets its ability from its nanostructure and should be easy to mass produce.

A team of researchers led by the University of Cambridge has developed a new technique that uses high-energy lasers to fine tune the properties of 3D-printed metal without compromising the complex shapes it forms.

Japanese scientists have developed a new type of plastic that can easily break down on demand into its base components. In seawater it starts to break down into food for marine life, and just to top it off, it can self-heal and remember past shapes.

Researchers have created a low-cost fiber that contracts in response to heat, resuming its shape when the heat is removed. Compatible with existing textile-producing machinery, the shape-shifting fiber could have a myriad of uses.

Scientists have developed what they call the most water-repellent surface ever. By giving it a liquid-like coating that defies usual designs, water will roll off the surface at angles 500 times shallower than other superhydrophobic materials.

Whether they're in machines, buildings or aircraft, it's always helpful to know if components are undergoing mechanical stress. A new material could quickly and easily let inspection personnel know, utilizing integrated glowing algae.

Everybody’s favorite wonder material, graphene, continues to surprise. MIT physicists have discovered yet another brand new electronic state hiding in this overachieving little material – something they give the bizarre name of “ferro-valleytricity.”

Inspired by a water-dwelling spider, researchers have created a novel surface material that stays dry for months underwater. They say the surface is easy to produce, scalable, and has a wide range of practical applications.

Researchers have turned lignin into nanoparticles that can create a transparent coating with antifog properties or a colorful antireflective surface, transforming this abundant waste product into a useful material with diverse applications.
