Greening your digital life
The less electricity you use while playing video games or using your devices, the less impact you’ll have on climate change.
- Computing
5G promises new energy savings for digital tech
A new way to transmit wireless communications promises time and energy savings by using networks of smaller cells.
- Science & Society
Machine learning includes deep learning and neural nets
By combining patterns found in mountains of data with information gleaned from mistakes, these computer programs expand their artificial intelligence.
- Archaeology
Unusual mud shell covers an Egyptian mummy
In ancient Egypt, commoners may have been mummified and then encased in mud to repair damage to the body or to imitate royal techniques used with royals.
- Brain
New technology can get inside your head. Are you ready?
New technologies aim to listen to — and maybe even change — your brain activity. But just because scientists can do this, should they?
- Earth
Space station sensors saw how weird ‘blue jet’ lightning forms
A mysterious type of lightning in the upper atmosphere has been traced to a brief, bright flash of light at the top of a storm cloud.
- Chemistry
Bye-bye batteries? Power a phone with fabric or a beacon with sound
New piezoelectric systems produce electricity in unusual ways, such as when a certain nylon bends or underwater ceramics vibrate.
- Tech
Computers are changing how art is made
Some people have challenged the idea that artificial intelligence can be creative. But new software can provide inspiration to artists or fully partner with them in the creative process.
