A light-powered microscope has a resolution limit of around 200 nanometers—which makes observing specimens smaller or closer together than that all but impossible. Engineers at the University of ...

Engineers have developed a technology that turns a conventional light microscope into what's called a super-resolution microscope. It improves the microscope's resolution (from 200 nm to 40 nm) so ...

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new dark-field imaging technique that does not require specialized microscope ...

This relatively simple circuit uses a 6-V DC supply with a PWM current-source configuration to provide efficient, adjustable dimming of a white LED over a wide range, needed to accommodate the unique ...

Mimiviruses are viruses so big they can actually be seen with a simple light microscope. European scientists have now learned that these bizarre organisms have their own immune system that makes them ...
