Cochlea Implants for Deaf and Severely Hard of Hearing

The cochlea implant (CI) replaces the function of the outer ear, the middle ear and the cochlea of the inner ear. Basically, it consists of an external unit comprising a microphone, speech processor,…

New Standard in Electrophysiology and Deep Tissue Imaging

The function of nerve and muscle cells relies on ionic currents flowing through ion channels. These ion channels play a major role in cell physiology. One way to investigate ion channels is to use…

Forensic Detection of Sperm from Sexual Assault Evidence

The impact of modern scientific methods on the analysis of crime scene evidence has dramatically changed many forensic sub-specialties. Arguably one of the most dramatic examples is the impact of…

Beware of "Empty" Magnification

This article explains how to avoid the phenomen of "empty magnification" in microscopy.

Quality as Clear as Glass - Polarizing Microscopy in Glass Production

An exquisite beverage deserves a high-quality glass. Even the ancient Romans made artistically crafted drinking glasses. In the Middle Ages, Venetian glassmakers were famous for the purity of their…
