Scheme illustration of object identification and all-optical 3D reconstruction system. (a) A contour surface image of the object can be obtained in a single processing of the system. (b) High-contrast ...

Floating displays you can reach into and manipulate, like the ones Tony Stark uses to design his super suits in the Iron Man movies, are one step closer to reality. A new device renders 3-D graphics ...

A tiny elephant establishes a new stomping ground for 3-D printing: inside cells. For the first time, scientists have 3-D printed objects within living cells, including a 10-micrometer long elephant ...

The basic lantern object is made by cutting a polymer sheet into a diamond-like parallelogram shape, then cutting a row of parallel lines across the center of each sheet. This creates a row of ...

Yes, it is possible to create a three-dimensional image of a four-dimensional object: a hypercube is the four-dimensional analogue of a cube, and it has a well-known three-dimensional image that looks ...

Although there are several methods of 3D-printing metal objects, all of them involve the application of heat – which isn't conducive to producing certain heat-sensitive electronics, among other things ...

The central objects of study in topology are spaces called manifolds, which look flat when you zoom in on them. The surface of a sphere, for instance, is a two-dimensional manifold. Topologists ...

Bats and dolphins are deservedly famous for their echolocation, but the elephantnose fish has a different superpower sense—electrolocation. And now new research suggests this bizarre-looking creature ...
