Möbius strips are special loops that only have one continuous side. Now we've built the smallest Möbius strips ever - out of DNA. Here you can see the nanometer-sized DNA loops, folded like origami.
The ability to create complex structures on the tiniest of scales is one of the great challeng... Read More
Coccidioides immitis. Spherule in lung abscess endospore. Gridley stain. (400X) Read More
Basidiobolus haposporus. Adhesive spores forcibly discharged and attached to cover of a petri dish. Lactophenol cotton blue stain Read More
This photomicrograph depicted a number of Gram-positive, endospore-forming Bacillus anthracis bacteria. B. anthracis is the pathologic microorganism responsible for the disease “anthrax”, an acute infectious disease, which most commonly occurs in wild and domestic vertebrates (cattle, sheep, goa...
