Aurora borealis over St Paul, Minnesota last night.

A few stress-free glimpses of our local nature in Minnesota

Happy birthday🎂, and keep your mother in your thoughts.

Sunrise over Eastern Greenland as seen from the air in 2019. Wish I could visit some day, but the chance of that is all but gone with the our current oligarchy.

For those in need of some color and hope and new life in these dark times, remember the beauty to come after the Winter.

Also, be sure to watch what may be very relevant very soon The Obsolete Man episode of The Twilight Zone by Rod Serling.

Cool. Have you seen this ad?

Dorsal rootlet nerve bundles immunostained for collagen IV (blue), UCHL1 (green) & neuropeptide (red/yellow). These sensory nerves carry information about pain, temperature, pressure, vibration, etc to the spinal cord and then to the brain to inform us about our physical condition.

I know it’s not great, but I wanted a Fluorescence Friday image. Epifluorescence microscope shot of a calcium channel subunit in dorsal horn from an antibody test iPhone image through the ocular lens. Sunrise-bright from too much background.🫣

Ripples in sand from eons before any multicellular life on Earth. Decayed from a road cut under a billion year old lava flow and found at Cutface Creek on the north shore of Lake Superior in Minnesota. The moonlit scene on this ancient shore was devoid of nothing but life and familiar stars.
