Artificial brains are far in the future, but computer chips that work like brains could keep computers advancing when today's silicon transistor chips reach their limit.
Layering substances like graphene in new ways could help us to build quantum computers or transmit electricity over long distances.
As electronic transistors get tinier, they approach a point at which they won't be able to get smaller. How can we keep shrinking our devices, and making them more powerful at the same time? Light.
As the components in electronic devices are shrinking to the nanoscale, even a single atom out of place can disrupt their function. But this also presents an opportunity to make them even better.
Big data is about processing large amounts of data. It is often associated with multiplicities of data. But the ability to generate data outpaces the ability to store it.
