Every time a computer stores or erases information, it uses energy. The amount is tiny for a single operation, but those operations happen billions of times every second. For decades, scientists have wondered just how little energy a memory device could use before reaching the fundamental theoretical limit set by the laws of physics.
Now, researchers have shown that it is possible to come close.

Storing memory on a chip with flowing water
Like the folds in crumpled sheets or the footprints on recently trodden sand, certain materials mark their histories. Now, Yale researchers show that networks of flowing water and other fluids can store their own memories—similar to how a computer chip does—an innovation that cou

Scientists may have found a shortcut to fusion energy
Princeton Plasma Physics Laboratory may have found a dramatically more efficient route to fusion energy by reversing the traditional approach: heating plasma first, then increasing its density. Their calculations could help future reactors reach self-sustaining fusion with far le
