Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape ...

Many industries rely on 3D-printed components, but their internal structures often limit strength and reliability. New ...

Abstract: In this paper we address the problem of matching two 3D shapes by representing them using the eigenvalues and eigenvectors of the discrete diffusion operator. This provides representation ...

On the course, a reliable draw can be the difference between playing defense and attacking pins, so we show how to build one you can trust under pressure. We cover the ball position, clubface-to-path ...

Decades of research has viewed DNA as a sequence-based instruction manual; yet every cell in the body shares the same genes – so where is the language that writes the memory of cell identities?

After more than three centuries, a geometry problem that originated with a royal bet has been solved. Imagine you’re holding two equal-size dice. Is it possible to bore a tunnel through one die that’s ...

Terry Rosoman ran almost 120km across south Wales to make a giant penis and testicles.Photograph: courtesy of Terry Rosoman In 2013, I was in the worst shape of my life. Though I functioned well day ...

Drawing 3D shapes is a useful skill for students, artists, architects, and anyone interested in visualizing objects more realistically. Unlike flat drawings, 3D shapes show depth, height, and width, ...

How a special nitinol compound and 3D printing was used to create the shape-shifting antenna. An overview of materials and heating problems they encountered, and how they overcame them. The test ...
