Materials

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 platinum fiddle that's just 35 microns in length and 13 microns in width is believed to be the world's smallest violin, measuring just a fraction of a microscopic tardigrade. But before you get too excited, there's one little twist …

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.

Researchers have genetically modified spiders for the first time using the CRISPR gene-editing process. Adding a single gene to unfertilized eggs resulted in the creation of a spider that could produce red, fluorescent silk.

As much as wind turbines are great for producing clean energy, disposing of them when the time comes can be challenging. Researchers in China have hit upon a clever way to use discarded blades to build long-lasting roads.

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.

Scientists have accidentally discovered a particle that has mass when traveling in one direction, but no mass while moving in a different direction. Known as semi-Dirac fermions, particles with this bizarre behavior were first predicted 16 years ago.

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.

Under the right circumstances, electrons can actually “freeze” into a bizarre solid form. Now, physicists at Berkeley Lab have created and taken the first ever direct images of this structure.

Researchers at UC Berkeley have invented a material in powder form that adsorbs carbon dioxide with astonishing performance. Just 200 g (a little under 0.5 lb) can suck up 44 lb (20 kg) of CO2, the same as a tree does in a year.

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.

A new type of carbon-neutral concrete has been commercially used for the first time, in a skyscraper being built in Manhattan. The binder utilized in the concrete is made of granite instead of traditional greenhouse-gas-emitting limestone cement.
