We’re falling in love with the crisp autumn air and with your favorite posts of the month. While diatoms and daphnia might be considered common, we don’t see anything common about these beautiful microscope images!

Diatoms are essentially tiny glass ornaments, which means they tend to produce chromatic aberrations themselves. These aberrations can be corrected with the proper objective lenses. This stunning image is of a Klaus Kemp diatom arrangement. To capture the diatoms with such detail, @macro__cosmos used Z-stacking as well as oblique illumination generated with the trinocular port dust cap partially covering the light port. We love seeing creative microscopy!

Fall is in the air, and with the changing of the leaves comes the arrival of all things pumpkin! This image shows the pollen grains of a pumpkin flower. Pumpkin flowers are not self-pollinating and require assistance from bees or human-induced pollination to improve the quality of the fruit. Without this help, we wouldn’t be able to enjoy our pumpkin spice lattes!

What’s cooler than an image of a radiolarian? An image of a lot of them! These spiky samples were picked up from calcareous rock collected in the Kanto region of Japan.

While some trees are already shedding their leaves, willows in your neighborhood may hold on to theirs for a while longer! They are among the earliest woody plants to grow leaves in the spring and the last to drop their leaves in autumn. These beautiful images show various views of a cross-section of a woody willow branch.

Daphnia pulex is the most common species of water flea. They can be found in a wide range of aquatic habitats, although they are most often connected to small, shaded pools. This pair was discovered in a pond at Bushy Park (located in Dublin, Ireland) and are seen here magnified 100x in the focus stack panorama.

Did you know you can find tardigrades (water bears) in moss? See how to find them in this quick video taken by Adolfo Sánchez-Blanco.

Adolfo commented, "Water bears are famous for being amazingly resistant to all sorts of extreme conditions. People often refer to them as immortal, but they are mortal like any other animal. However, when the environmental conditions are adverse, they enter into a state of suspended animation called cryptobiosis. It is when they enter into cryptobiosis that they can withstand the incredibly harsh conditions that give them the reputation of being immortal."

If you try this and find some water bears, let us know!
