Scientists have been working on enhancing concrete to store energy. That includes researchers at MIT, who found a way to combine cement, water, and carbon black to create a 'supercapacitor' for this purpose back in 2023. It's now 10x better at this.

If an object that's composed of two types of material is going to fail, the break will usually occur at the interface where the two meet. A new type of light-activated 3D printing resin addresses that problem, by gradually morphing from hard to soft states within a single object.

A Maryland-based startup is set to begin mass producing Superwood, which is made from regular timber using a densification process, and exhibits strength greater than that of steel.

A reusable formwork design for molding concrete into vaulted floors using sophisticated structural geometry uses 60% less concrete and 90% less steel compared to traditional methods. It's also inexpensive and doesn't require special skills.

From a handheld soldering gun to the 'playbird mansion' and, of course, the marvel of a smartphone microscope, there are some gadgets that we come across that we instantly want – and this wireless ultrasonic cutter is definitely another.

Researchers at MIT have unexpectedly stumbled upon a way to 3D print active electronics – meaning transistors and components for controlling electrical signals – without the use of semiconductors or even special fabrication technology.

While clay is widely used to build basic structures such as huts, we typically don't see it being utilized in large-scale construction projects. That could soon change, however, thanks to a recently developed process known as impact printing.

Metalworking usually requires very high heat and pressure, but scientists in Singapore have now demonstrated a way to make very pure metal structures at room temperature. It’s inspired by the exoskeletons of crabs and insects.

The 3D printing of certain items could soon get a lot faster, simpler and more eco-friendly. That's because scientists have developed a new 3D printing ink which is easily extruded as a liquid, then solidifies on contact with a saltwater solution.

It’s ironic that while many regions struggle with water shortages, there’s heaps of the stuff floating around in the air everywhere. A new MIT water harvester design can pull enough fresh water out of the air to meet the daily needs of several people.

Your boots may soon have a tropical touch, with a breakthrough in using pineapple leaves to make a strong, 100% natural, sustainable leather. It comprehensively outperformed mushroom leather, and has serious potential for scalable, commercial use.

If you think these bricks look so simple even a robot could build a house with them, you'd be right. Plaex, the startup behind them, sees an automated construction industry in our near future, where materials will adapt to suit a new robotic workforce.
