Resistors that remember help circuits learn
Electronic components called memristors have enabled a simple computing circuit to learn to perform a task from experience.
- Psychology
On Facebook, you control the slant of the news you choose
Facebook users shield themselves from opposing political ideas more than the site does.
- Science & Society
Working together doesn’t always work
Working as a team is a great way to gather information, but innovative solutions come best from small groups or individuals, a new study suggests.
- Neuroscience
Brain’s grid cells could navigate a curvy world
If we ever need to flee a dying Earth on curved space islands — as humanity was forced to do in 'Interstellar' — our brains will adapt with ease, a new mathematical analysis suggests.
- Tech
‘Ex Machina’ explores humanity as much as AI
Sci-fi thriller delves into hubris and power relationships.
