Through a field called geometric topology, mathematicians like me study all possible spaces in all dimensions. Whether trying ...

Wherein most 3D printers are designed to create objects that have to remain rigid in structure and shape, 4D printing, as it is called, allows the 3D printed objects to change their shape and ...

New 4D bioprinting lets tissues change shape and grow stronger, bringing science closer to real, working lab-grown organs. (CREDIT: Adobe Stock) During the early stages of life, organs do not just ...

This KS2 maths article explains how to sort 2D and 3D shapes according to their properties using Carroll diagrams and Venn diagrams, ... Slide 1 of 3, Five 2D shapes in different colours: ...

New shape-changing 4D materials hold promise for morphodynamic tissue engineering. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2021 / 02 / 210225082443.htm ...

The 4D material changes shape in response to water. The grey side of the material in the image absorbs water faster than the blue side, causing it to bend into a "C" shape.

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 ...

Recent advances in large- scale, label-free, and multiplexed fluorescence 3D imaging have unlocked novel insights into the organization of kidney micro-environments in health and disease. These ...

Scientists printed tissues in their final shape, hoping they would work like natural organs. But this approach failed to copy the active shaping that happens during early development.

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