Scientists discover bacteria that survives solely by eating electricity

Researchers at Harvard and Yale have used some extreme gene-manipulation tools to engineer safety features into designer organisms.

This work goes far beyond traditional genetic engineering, which involves moving a gene from one organism to another. In this case, they're actually rewriting th... Read More

Streptomyces albus

Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... Read More

Swarming Motility/ Proteus mirabilis

A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
