Gut microbes' partnership helps body extract energy from food, store it as fat

...archaea from the human intestine in 1982, and have recently recognized M. smithii as the most common archaeon in human intestines. In addition to its prevalence, M. smithii was an intriguing target for study because of its ability to consume hydrogen and other byproducts of bacterial digestion of polysaccha...

NYU researchers decorate virus particles, showing potential to enhance MRI capabilities

...ed in a very precise array. Other researchers have recently sought to enhance MRI capabilities through the use of similar large molecular assemblies by increasing the size, and therefore signal, of MRI contrast agents. They have also tried to use this terrain to facilitate "multi-modality," in which a set of ...
