Corona virus
Once inside the cell, the virus releases genetic material that effectively tricks the host cell into replicating the invading virus thousands of times. A swarm of new virions eventually burst through the cell wall and move on to infect other cells. That moment is pictured here in a cell from an American COVID-19 patient.
For the Chemistry geeks:
AFM (colorized images, top) visualizes the starting material, radical intermediates, and product from an STM-driven reaction (bottom).
Leo Gross of IBM Research Zurich and coworkers there and at the University of Santiago de Compostela used scanning tunneling microscopy (STM) to push a molecule to react and atomic force microscopy (AFM) to image atomic-level details of that molecule as it formed radical intermediates and a final product.
Okay, another great round of awesome pics from participants so I’m gonna give the win to maniakman! They look so colorful and alien. Almost looks like mixed nuts you get at the local supermarket bulk bin section. Plus I have allergies so I can relate to the pic somewhat. 
Alright… lets go “upstream” in the supply chain and see some cool pictures of the source of the pollen….
When I got my first 35mm SLR as a kid I took way too many pictures of flowers … and back then you had to wait 2 weeks before you could see the results…
THE CALEANA MAJOR
This black orchid known as the flying duck will have you look at it in awe and surprise
Bee-covered pollen.

Hug those stamens!

Dang!
You guys made it hard to chose.
In the end it was a coin toss between “Godzilla Bee” and “Hot incoming chopper”….

Thanks!
Sorry to be late responding on this one - busy weekend.
Show me pictures of whole fields of flowers.
