Companies can't verify that their source didn't involve artisanal mining. A discussion over responsible sourcing strategies and practices is needed.
Batteries power much of modern life, from electric and hybrid cars to computers, medical devices and cellphones. But unless they're made easier and cheaper to recycle, a battery waste crisis looms.
A new silicone 'skin' contains electronics that mimic the human body's lightning-fast response to pain, potentially paving the way for smart prosthetics that can detect painful sensations.
Demand for electric and electronic products is fuelling the meteoric rise in e-waste.
There is an urgent need for greater awareness of the dangerous substances found in the environment.
The most thoughtful gifts can also be the most sustainable, and last long after Christmas has ended.
Engineers predict a time when people and robots physically interact all day long. For that to happen safely will require new soft materials that can do things like sense touch and change shape.
M. Stanley Whittingham, John B. Goodenough and Akira Yoshino made the batteries in our pockets possible.
Manufacturing quantum computers would be a lot easier with existing technology than the exotic components currently used to build them.
The typical American's annual household carbon footprint is over five times the world per capita average.
Our brains create new memories, and forget old ones, by forging and breaking connections between nerve cells. Now researchers can do something similar using a light-sensitive electronic chip.
Phosphorene nanoribbons are like tagliatelle, but carry the potential to boost battery capacity by 50%.
When teenagers sleep for less than eight hours a night, they are at increased risk of suicide, being overweight, high rates of injury, poor sustained attention and low school grades.
Technological advances and discoveries are moving at a rate faster than engineering education can keep up with. The solution is a revised approach to teaching engineering.
Buttons don't always make things easier – and using them can be fraught with peril and troubling power dynamics.
Americans are spending almost three and a half hours on their phones and tablets every day, twice the amount just five years ago. A behavioral scientist offers a few tips on how to take control.
Cybersecurity efforts could take a lead from open-source software, creating hardware whose designs are open for all to see and examine.
After two decades of work, the technical challenges of a bendable screen may have been overcome.
Paper-based devices with foldable, biodegradable batteries provide a new way to reduce electronic waste. But how would these new gadgets work?
