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.
Six hours of streaming video may be the equivalent of burning one litre of petrol.
With online learning, children are staring at computer screens for more hours each day.

With online learning and social distancing, kids are spending more time staring at screens and less time outdoors. That can put them at higher risk of myopia and serious eye problems in the future.

Electronic waste is accumulating and is a resource to be exploited. Microfluidic devices allow the development of recycling, including the recycling of rare earths – a precious resource.
Windows 7 users are being urged to buy a new laptop but they could be just as well off not bothering.
When algorithms make decisions with real-world consequences, they need to be fair.
A machine learning expert predicts a new balance between human and machine intelligence is on the horizon. For that to be good news, researchers need to figure out how to design algorithms that are fair.
Many Kenyan students have had limited access to computers.
Integrating technology into schools involves understanding the dynamic relationship between technology, how it's used in the classroom and the content of the curriculum.
Coding can enhance children’s creativity and their understanding of mathematics.
Coding is beneficial to children, irrespective of their career path later on in life.
Will quantum computers ever reliably best classical computers?
Google claims quantum supremacy – IBM says not so fast. One researcher explains why he doesn't see quantum computers outpacing classical computers any time soon ... and maybe not ever.

The first computer, named the ABC, was built at Iowa State University. But for a long time, few had heard of it.
Researchers have developed implants small enough to fit inside brain cells.
An algorithm is just following rules designed either directly or indirectly by a human.
Algorithms are only human (well, designed by humans) but we need to trust they'll do what they're supposed to do. And that means we need a better way to test them.

The head of Google's Quantum AI Labs, Hartmut Neven, claims the current speed of development means a quantum computing breakthrough is near.
Humans are the weak link in cyber security. But there may be a solution to making us safer, using the technology of exercise and lifestyle apps
Many other key arrangements have been tried. Some are claimed to be easier to learn or faster to use than QWERTY. But none has proved good enough to beat QWERTY.
The earliest typewriters had the letter keys in alphabetical order. The trouble was that if you hit two keys quickly the levers would jam.
Society needs cybersecurity professionals who can protect systems and mitigate damage.
The first thing to know is that Siri is not a "who" – Siri is a "what".
