From A to Z: Our Most Popular Microscope Images for February 2021

February popular microscope images

While February is a short month, it was still full of beautiful images. From A to Z – that’s algae to zooplankton – here are the top images.

microalgae

This month’s most popular image is the second in our new series with Håkan Kvarnström, "Exploring the Microscopic World with X Line Objectives."

Botryococcus braunii is a microalga notable for its copious oil production. In this image, you can see droplets of oil around the edges that were squeezed out of the specimen as water evaporated and the coverslip began to press down on the specimen.

To capture this focus stacked image, Håkan used the X Line 60X oil immersion objective (UPLXAPO60XO) with a numerical aperture (NA) of 1.42. The false-coloring effect was created by deliberate misalignment of the differential interference contrast (DIC) setup.

“The X Line 60X objective gave me the ability to resolve details that were hard to see with my other objectives. Its working distance is also considerably higher, so I can capture thicker specimens without losing sharpness and resolution.”

Keep your eyes peeled for next month's image to learn more about DIC imaging!

silicoflagellate

During their life cycle, Silicoflagellates produce a siliceous skeleton composed of a network of bars and spikes arranged to form an internal basket. Known as microfossils, these skeletons comprise 1–2% of the siliceous component of marine sediments. They evolved 120 million years ago during the Cretaceous, with the greatest abundance and diversity occurring during the Miocene, 25 million years ago.

Bigger isn’t always better, especially in microscopy! This series of images shows how it is possible to reveal structures and dynamics at the nanoscale with Olympus optics and Abbelight’s barrier-breaking single-molecule localization microscopy (SMLM) technology.*

protozoan

It’s not easy being green? It is for this protozoan! Known for its remarkable regenerative characteristics, it's able to grow back into a complete organism from a fragment as small as 1/100 its original size!

Horsetail

Did you know? The non-flowering evergreen perennial, horsetail dates back to Paleozoic times, some 350 million years ago. Like bamboo, it has vertical green stems with horizontal bands, and like ferns, its reproduction occurs through spores rather than seeds. However, horsetail is unrelated to bamboo or grass or ferns.

We always love our Instagram Takeovers when we hand the reigns over to microscopists and share the amazing work being done out in the world. This month, Gabrielle Corradino showed us her passion for plankton. Below are two of her zooplankton images.

“What are zooplankton? Zooplankton are the animal-like plankton that have to hunt for their food within the water column. The water column is the area of water from the surface down to the sediment. During the daylight hours, zooplankton generally hang out in deeper waters to avoid predators. At night, these microscopic creatures venture up to the surface to feed, making this the largest migration on Earth. Check out @NASA images to see this migration from space!

Many species of zooplankton can be seen without a microscope and often look like tiny dots swarming around the water column. Common captures from a tow (a plankton net) include euphausiids (think krill!) and copepods. These are important grazers in the biological pump and can range from the poles to the warm tropics.”
