Real-time imaging of cell components including DNA

Optical microscopes that use lenses to bounce photons off objects have trouble distinguishing nanometer-scale objects smaller than the imaging beam's wavelength, such as proteins and DNA. An innovative 'hyperlens' designed ...

Laser heating hits the spot

A method for accurately measuring the thermomagnetic properties of heat-assisted magnetic recording (HAMR) media reveals what the minimum bit size and ultimate data density might be for this next generation storage technology.
