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 ...

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 ...

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 ...

You say that the human brain is the most complex object in the known universe (Leader, 22 June). But it is part of the human body, which is an object, and so must be the most complex. But humans are ...

If we want to understand complex constructions, such as ourselves, assembly theory says we must account for the entire history of how such entities came to be. Life on other worlds — if it exists — ...

Researchers have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-based parts. To achieve this, they used ...

In a recent project, I needed an easy way to traverse Java object trees and extract values from the objects. Instead of continually going through huge iterator-if-else setups, I wanted a tool that ...
