Researchers use novel imaging to predict spinal degeneration  

A main cause for spinal disc degeneration is thought to be a change in the water content in the intervertebral disk. A research team used a novel magnetic resonance imaging technique, called apparent diffusion coefficient (ADC) maps, which directly assessed the movements and dynamics of the water in the intervertebral disk and other spinal structures. The ADC maps provided precise assessments and correlations with degeneration.

How the smallest bacterial pathogens outwit host immune defenses by stealth mechanisms  

Despite their relatively small genome, mycoplasmas can cause persistent and difficult-to-treat infections in humans and animals. A study has shown how mycoplasmas escape the immune response. Mycoplasmas 'mask' themselves: They use their small genome in a clever way and compensate for the loss of an enzyme that is important for this process. This could be shown for the first time in vivo, thus representing a breakthrough in the research of bacterial pathogens.
