Researchers have developed a label-free and non-invasive Raman spectroscopy approach that can acquire microscopic images of biological samples and identify a wide range of biomolecules with unprecedented speed and sensitivity. The new technique is based on coherent anti-stokes Raman scattering (CARS) microscopy. The method could eventually make it easier and faster to diagnose cancer by allowing the visualization of the chemical constituents of human tissues and cells.

A pioneering genomic surveillance study has provided the clearest picture yet of the arms race between Streptococcus pneumoniae, the bacterium responsible for a range of illnesses such as pneumonia and meningitis, and the vaccines designed to protect against the most dominant types. A strain called GPSC10 was found to be a particular threat, due to its increased virulence, ability to transform its structure to evade vaccines and its resistance to several common antibiotics.

Over three million people are infected with the hepatitis E virus every year. So far, no effective treatment is available. An international team has investigated which factors are important for the virus in the course of its replication cycle and how it manages to maintain the infection. The researchers analysed various mutations of the virus and found changes that may allow the virus to trick the immune system.

In a small study, motion analysis of video recorded on a smartphone accurately identified narrowed neck arteries in adults, which are a risk factor for stroke. The smartphone video motion analysis technology may be an early screening tool for detecting narrowed arteries in the neck, which may improve patient outcomes.
