How the body fights off urinary tract infections

Some people are better protected than others against urinary tract infections. This may be because their bodies produce more of a protein called uromodulin. An interdisciplinary research team has now found out exactly how ...

Lens-free microscope can detect cancer at the cellular level

UCLA researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes.

Optical microscope

The optical microscope, often referred to as the "light microscope", is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. Optical microscopes are the oldest and simplest of the microscopes. However, new designs of digital microscopes are now available which use a CCD camera to examine a sample and the image is shown directly on a computer screen without the need for expensive optics such as eye-pieces. Other microscopic methods which do not use visible light include scanning electron microscopy and transmission electron microscopy.
