The brain’s cerebral cortex produces perception based on the sensory information it’s fed through a region called the thalamus.
Modern computers contain tens of billions of switches, called transistors, that pass electrical signals to process inputs and outputs—serving as the basis for computation.
The accumulation of plastic waste in the oceans, soil, and even in our bodies is one of the major pollution issues of modern times, with over 5 billion tons disposed of so far. Despite major efforts t...
In a single day, enough sunlight strikes Earth to power the world for an entire year—that is, if we can find a way to capture that energy cheaply and efficiently. While the cost of solar energy has de...
Wireless charging roads equipped with energy storage systems are promising electric vehicle solutions by virtue of their strong advantages in time saving and reduced pressure on the existing power inf...
