"Mommy Bloggers are widespread, but nothing deserves the “ubiquitous” label more than bacteria." Driving into work this morning, I was listening to an interview inspired by Mother’s Day. The radio hosts were talking to a Mommy Blogger (apologies for not recalling her name). What amazed me was a statistic that was given indicatin
Dendritic cell and lymphocyte, coloured scanning electron micrograph (SEM). Interaction between a dendritic cell (blue) and a T lymphocyte (yellow), two components of the body's immune system. Both are types of white blood cell. T lymphocytes recognise a specific site on the surface of pathogens or foreign objects (antigens), bind to it, and produce antibodies or cells to eliminate that antigen. Dendritic cells are antigen- presenting cells (APCs), they present antigens to T lymphocytes…
The acantharians are one of the four types of large amoebae that occur in marine open waters. "Large" in this case is relative, as this microscopic creature have skeletons made of a single crystal of strontium sulfate that quickly dissolves in the ocean water after the cell dies. Together with other microscopic organisms, though, amoebas like this account for most of the biomass on Earth.
Colorized low-temperature electron micrograph of a cluster of E. coli bacteria. Individual bacteria in this photo are oblong and coloured brown. As an alternative to using antibiotics for fighting E. coli infections in newborn and weaned pigs, scientists are finding promising results from introducing mixes of beneficial bacteria, obtained from other pigs, into the gut of young pigs.
Cochlea from Inner Ear. Color-enhanced scanning electron micrograph of the inside of a guinea pig inner ear showing the hearing organ, or cochlea. Running along the spiral structure are rows of sensory cells which respond to different frequencies of sound. The whole organ is just a few millimeters long.
Hospital-associated Methicillin-resistant Staphylococcus aureus (MRSA) Bacteria. Interaction of MRSA (green bacteria) with a human white cell. The bacteria shown is strain MRSA252, a leading cause of hospital-associated infections in the United States and United Kingdom.
