Understanding the thermodynamic cost of timekeeping

Clocks are essential building blocks of modern technology, from computers to GPS receivers. They are also essentially engines, irreversibly consuming resources in order to generate accurate ticks. But what resources have ...

Method offers inexpensive imaging at the scale of virus particles

Using an ordinary light microscope, MIT engineers have devised a technique for imaging biological samples with accuracy at the scale of 10 nanometers—which should enable them to image viruses and potentially even single ...
