Researchers create flow-driven rotors at the nanoscale

Researchers from TU Delft have constructed the smallest flow-driven motors in the world. Inspired by iconic Dutch windmills and biological motor proteins, they created a self-configuring, flow-driven rotor from DNA that converts ...

Using steampunk to explain quantum physics

What do quantum computers have to do with smog-filled London streets, flying submarines, waistcoats, petticoats, Sherlock Holmesian mysteries, and brass goggles?

Artificial intelligence, the future of work, and inequality

One of the most spectacular facts of the last two centuries of economic history is the exponential growth in GDP per capita in most of the world. Figure 1 shows the rise (and the difference) in living standards for five countries ...

The thermodynamics of computing

Information processing requires a lot of energy. Energy-saving computer systems could make computing more efficient, but the efficiency of these systems can't be increased indefinitely, as ETH physicists show.

Video: When water levitates

Have you ever seen a drop of water navigate a maze? It's possible thanks to the same phenomenon that lets you know if a griddle is hot enough for pancake batter. Water droplets that dance and skitter across a hot surface ...

Medieval water power initiated the collapse of salmon stocks

Salmon largely disappeared from the Netherlands due to the construction of water mills, ecologists from Radboud University conclude (Scientific Reports, 20 July). The construction of water mills caused the destruction of ...

27 of Einstein's personal letters going on auction block

When he wasn't busy scribbling out the theory of relativity, Albert Einstein seems to have spent a fair amount of time writing letters involving topics such as God, his son's geometry studies, even a little toy steam engine ...
