Improvements in three-dimensional (3D) scanning have enabled quick and accurate scanning of 3D objects, including cultural heritage objects, as 3D point cloud data. However, conventional ...

Magnetic invisibility sounds simple in theory. Place the right materials around an object and magnetic fields flow around it as if nothing were there. Reality has been far messier. For nearly two ...

Researchers in Europe have developed a technique for obtaining accurate laser-based measurements of objects hidden behind complex scattering structures. They say that their mathematical formula, which ...

Taking advantage of molecules that switch states when exposed to particular wavelengths of light, researchers have developed a 3-D printing method that can make precise objects in a matter of minutes.

Previous investigations of the neural code for complex object shape have focused on two-dimensional pattern representation. This may be the primary mode for object vision given its simplicity and ...

Imaging buried objects Left: artistic impression of metal spheres buried in small glass beads; centre: conventional ultrasound image; right: the new technology can precisely determine the positions of ...

3D printing is super cool, but it's also super slow -- it would take 115 days to print a detailed, multimaterial object about the size of a grapefruit. A new method allows printing with up to 8 ...

[Matthias], eminent woodworker he is, designed and built an awesome machine to make copies of just about any object imaginable. With a few scrap 2x4s, and a few bolts, screws, and skateboard bearings, ...
