Philadelphia artist Kate Kaman (www.katekaman.com) has designed a dynamic larger-than-life sculptural depiction of the most plentiful and ancient microscopic life forms -- bacteria. Suspended throughout an area measuring approximately 130 feet long, 27 feet wide and 41 feet tall, “The Unseen Wor... Read More

This microscopy image provided by Dr. Carl June, shows immune system T-cells, center, binding to beads which cause the cells to divide. The beads, depicted in yellow, are later removed, leaving pure T-cells which are then ready for infusion to the cancer patients. Scientists are reporting the fi... 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...
