Using a new technique known as 4D printing, researchers can print out dynamic 3D structures capable of changing their shapes over time. Such 4D-printed items could one day be used in everything from ...

Nowadays, 3D printing allows items to be created from a wide variety of materials — plastic, ceramic, glass, metal and even stranger ingredients such as chocolate and living cells. The machines work ...

During the early stages of life, organs do not just appear in their final form. They take shape through a process of controlled bending, twisting, and folding. These changes help cells organize into ...

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

(Nanowerk News) New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs ...

(Nanowerk Spotlight) The next generation of robots may not look anything like the rigid, mechanical machines we’re used to. Instead, imagine a robot that moves more like an octopus or a human hand, ...
