Swift 4-D printing with shape-memory polymers

Shape-memory polymers or shape-shifting materials are smart materials that have gained significant attention within materials science and biomedical engineering in recent years to build smart structures and devices. Digital ...

Tiny heat engine may be world's smallest

(PhysOrg.com) -- Steam engines, combustion engines, and diesel engines are all different types of heat engines, which operate by converting heat energy into mechanical work. Although heat engines have existed for a long time, ...

Device could jumpstart work toward quantum internet

In research that could jumpstart work toward the quantum internet, researchers at MIT and the University of Cambridge have built and tested an exquisitely small device that could allow the quick, efficient flow of quantum ...

Building robust optical structures made of darkness

Optical devices and materials allow scientists and engineers to harness light for research and real-world applications, like sensing and microscopy. Federico Capasso's group at the Harvard John A. Paulson School of Engineering ...

Self-folding origami machines powered by chemical reactions

A Cornell-led collaboration harnessed chemical reactions to make microscale origami machines self-fold—freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.

Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...
