Imagine a more sustainable future, where cellphones, smartwatches, and other wearable devices don’t have to be shelved or discarded for a newer model. Instead, they could be upgraded with the latest sensors and processors that would snap onto a device’s internal chip — like LEGO bricks incorporated into...

Researchers have discovered a single-molecule switch that can act like a transistor and store binary information. The molecule is around five square nanometers in size — more than one billion of them would fit onto the cross-section of a human hair.

It is 5 p.m., and you arrive home from work when it is peak demand for the grid. Your electric vehicle (EV) is 50% charged — you could either plug it in and charge right away or, if it works for your plans, schedule the vehicle to charge at a better time for the grid.

A group led by Jane Wang, Professor of Mechanical and Aerospace Engineering in the Cornell University College of Engineering, has untangled the intricate physics and neural controls that enable dragonflies to right themselves while they're falling.
