Serratia spp. are widely distributed in nature. Serratia marcescens is the most common Serratia sp. associated with human disease, followed by strains of the S. liquefaciens complex: S. liquefaciens, S. grimesii and S. proteamaculans. The clinical significance of these species is largely unknown... Read More
2009 Nikon Small World Competition award 10th place: Leave it to the diminutive diatoms to bring out algae's best side. Only 10 times larger than life, this image was captured via dark-field by Arlene Wechezak in Anacortes, Wash. Such diatoms have been proposed as a key biofuel source of the fut... Read More
Malaria’s impact worldwide is still an issue, particularly in developing countries. Research is ongoing to study the carriers of malaria, mosquitoes, and how they carry and transmit the disease and other pathogens. That’s why the 2010 winning image by Jonas King is so important to the life scien... Read More

Helicobacter pylori (yellow), a common bacterium that lives in the stomach lining, increases the risk of stomach cancer (brown cells) and peptic ulcers. But over time H. pylori can reduce stomach acid and acid reflux, which may help fend off esophageal cancer. The microbe also appears to help pr... Read More
