Cathodoluminescence image of a chondrule from a primitive meteorite. Chondrules are small melt droplets consisting of silicate minerals such as olivine and pyroxene (pink grains), along with glass (green-blue material between the pink grains). The presence of chondrules tells us that this is a primitive meteorite – one that came from an asteroid that formed around 4.5 billion years ago, and has remained unmelted ever since. Cathodoluminescence images such as this one can provide information on the trace elements present in the sample, which in turn provides information about conditions in the early solar system.

Negative stain TEM image of a novel tymovirus, Naranjilla Chlorotic Mosaic Virus (NarCMV) isolated from symptomatic leaves of a popular citrus variety, naranjilla, which is commonly cultivated in the Andes for fresh fruit and juice production. Previously there had been no other reports of viral infections on naranjilla, however this new virus represents a potential significant threat to the economy of Ecuador.
