Researchers have invented nano-optical tweezers capable of trapping and moving an individual nano-object in three dimensions using only the force of light. Using this approach, they have demonstrated ...

Exploration of the fourth dimension, well-known in literature and theoretical physics, became a realistic theme only a few years ago. This leap was made when the first object was printed using 4D ...

Imagine shrinking Earth to the size of a small ball to reveal just how vast the Universe is. If it were 12 centimeters wide, ...

Cells are minute—typically too small to be seen by the human eye. Even so, the cellular world encompasses a range of scales, from roughly a tenth of a nanometer (10 −10 m) to a millimeter (10 −3 m) or ...

Despite all the technological advances over the years, measuring items in your home still tends to involve old-school rulers and tape measures... and they can be inaccurate if there are curves.

Mathematicians, freed in their imaginations from physical constraints, can conjure up descriptions of objects in many more dimensions than that. Points in a plane can be described with pairs of ...

4D, most known in science fiction and theoretical physics, is being actualized by the 4D printing technology developed at MIT’s Self-Assembly Lab. This breakthrough enhances conventional 3D printing ...
