Thejoyofscience - This Is For All The Nerdy Girls

Microbiologists have learned how a probiotic bacterium used to treat irritable bowel syndrome can soothe gut bacterial infections caused by salmonella, paving the way for potential relief from foodborne illnesses that affect millions of people annually.

This bad little boy is super rare to find!!!  This is a mitotically active cell present in peripheral blood circulation from a dog - only the second one I have ever seen!!

As a game, in the diagnostic lab we yell KABLAM! anytime we see a mitotic figure.  The first one to say kablam wins :-P  We should so turn it into a drinking game…

Kim Weaver (b. 1964) is an astrophysics professor and astronomer. She is an expert in x-ray astronomy and has worked for NASA’s Goddard Space Flight Center.

She obtained her PhD in astronomy in 1993 from the University of Maryland. After that, she was a research scientist at Penn State and John Hopkins University. Her honours include the Presidential Early Career Award and the NASA Peer Award.

Cutaneous mass on the right flank of a 2 year-old, female-spayed, black Labrador Retriever.  The owner noticed the mass approximately a week earlier, and it has been growing in size every day.  On palpation, the lesion was quite painful.  The dog also had a fever, at 103.5°F.

Fine needle aspiration revealed copious inflammatory cells.  Mainly neutrophils, with lesser numbers of macrophages.  Notice how some of the neutrophils appear ragged, some borderlining on unidentifiable?  Such changes are consistent with a degenerative change, which usually occurs in the presence of a bacterial agent.  And speaking of bacteria, there are TONS.  A mixed collection of cocci and filamentous rods (red arrow).  The presence of filamentous rods is often associated with plant foreign material (like a ‘grass awn’ or ‘cheat grass’).

*

Diagnosis: Marked, septic, suppurative inflammation with necrosis.  Basically an abscess.  A key piece of history…the patient is a hunting dog and partook in some field trials a few days before the mass developed.  The patient is slated to have the mass surgically explored in hopes of finding planet debris.

New neurons (in green) are guided to the neocortex  - responsible for controlling language and movement - not by glial cells, but by a protein called reelin.
