Scientists lay out why some origami won't fold under pressure

Scientists and engineers are fascinated by self-folding structures. Imagine the possibilities: heart stents that unfold in the right location or pop-up tents that assemble at the press of a button, as well as nanoscale versions ...

Meet the tiny machines in cells that massacre viruses

When viruses infect the body's cells, those cells face a difficult problem. How can they destroy viruses without harming themselves? Scientists at University of Utah Health have found an answer by visualizing a tiny cellular ...

Nobel: Big hopes rest on tiny machines

Molecular machines, which earned their inventors the Nobel Chemistry Prize on Wednesday, are a fraction of the width of a human hair but strong enough to move things 10,000 times their size.

Microbots individually controlled using 'mini force fields'

Researchers are using a technology likened to "mini force fields" to independently control individual microrobots operating within groups, an advance aimed at using the tiny machines in areas including manufacturing and medicine.
