This #MicroscopeMonday comes from @tardibabe on our BX53 system! 🔬 This awesome video features a Stephanoceros fimbriatus rotifer! "Rotifers are also referred to as « Wheel Animals » because of the rotating cilia, called corona, they have on their heads! They usually use these cilia to create a water current that attracts food particles like bacteria, algae, ciliates and other microorganisms to the mouth. Although this species is a bit different from the other rotifers. Instead of having some rotating wheels on their heads, they have five long tentacles with moving cilia that redirect preys toward the mouth! These rotifers are basically ambush predators waiting for preys to pass by. Preys then get trapped into small compartments before getting pumped by sphincter muscles and ultimately being swallowed. Most rotifers are planktonic and swim around but Stephanoceros fimbriatus is sessile, their adult stage is immobile. When in their larval stage, they swim around until they find a nice spot to stay for the rest of their lives. I found this one sticked to an hydra, which is kind of odd since the hydra could easily have eaten the rotifer." Looking to get into the fascinating world of microscopy?

Plants take up carbon dioxide and release oxygen, but how do gases actually move in and out of a leaf? In this video, you can see oxygen gas being released from a spider plant leaf. . Why do plants take in carbon dioxide? Plants need carbon dioxide to carry out photosynthesis, which is their way of making their own food from scratch. They do so by reactions involving carbon dioxide and water. This process is powered by sunlight energy. . How do plants take in carbon dioxide and release oxygen? Because carbon dioxide is a gas, plants use tiny pores that open and close to allow carbon dioxide to enter the plant. These pores are called stomata and are usually very abundantly located on the underside of the leaf. As a byproduct of photosynthesis, oxygen (another gas) is generated (this is the very oxygen that we breathe!). That oxygen exits the plant through the same pores (stomata) that the plant uses to take up carbon dioxide. . In other words, stomata are the “mouths” that plants use to “breathe” (do gas exchange). The bubbles you see forming on the leaf are due to oxygen leaving through these microscopic openings. . Unavoidably, every time that stomata open, water vapor escapes the plant too (transpiration). As water evaporates from the leaves, it creates a negative pressure that pulls water (and dissolved minerals) up from the roots into the plant. This is basically the force that allows roots to “suck up” water and nutrients from the soil into the plant!! . Plant biology is fascinating! . For this video I used a Leica ZOOM 200 stereoscope and an Olympus BX41 microscope at up to 400x magnification #microscopy #stomata

How can you observe tardigrades? You take a look at moss: their natural habitat! Our friend @tardibabe took a look and found tardigrades from two genera: Milnesium and Macrobiotus. Milnesium tardigrades have long, pointy claws and a decorated snout, which help them grab, manipulate, and stabilize their prey. Macrobiotus have shorter claws and a simpler snout, which makes them vegetarians feeding off of algae and plant cells, with the occasional relapse into a carnivorous diet when feeding on microscopic animals. It also allows them to slurp out of air bubbles. These animals highlight some of the biodiversity that can be found in microscopic environments! @Tardibabe safely returned them to their natural habitat after taking a quick look. #Science #Microscope #Microscopy #Animals #Tardigrade

Inside a drop of water, this tiny animal is running a microscopic feeding machine. Looks like this is a Bdelloid rotifer. The spinning “propeller” at the front isn’t a wheel at all. it’s thousands of tiny beating hairs called cilia creating currents that pull food straight into its mouth. At this scale, water behaves more like syrup than the water we know, so these creatures evolved clever ways to move and feed. #microscopy #microbiology #smallthingsbigwonders #hiddenworld #microorganisms

A tardigrade!!! 😱 Here are the microorganisms I found: 1. Water fleas. These are microscopic crustaceans named Scapholeberis! I love how they have a little spike and some black pigments. These melanin pigments are found on the body parts facing towards light. Some research have shown that melanin would protect these creatures from photo damage! 2. Water bear. Found this little tardigrade walking around some green algae! Check out my tardigrade posts to learn more about them little babes 3. Red water mite. Unlike spiders, their close relatives, mites found ways to colonise under water habitats. There are thousands of aquatic mite species, mostly living in freshwater springs, streams, lakes and temporary pools, although some can be found in salt water 4. Mosquito pupa. Mosquitoes go through 4 stages: eggs, larva, pupa and adult! Here you can see the pupa with the future eyes and antennae. 5. Phacus gigas. This green leaf is an algae that can be found in freshwater habitats around the world. They swim with their flagellum located in front of the cell. The red eyespot is a photoreceptor responsible for detecting light! With this, Phacus can orient itself and swim toward a light source and ultimately produce energy by photosynthesis! 6. Gieysztoria sp. A free-living flatworm gliding aided by thousands of cilia. This one was around 0.7mm and you can even see their little black eyes, used to detect light 7. Synchaeta sp. This is a planktonic rotifer that usually zoom around super fast. Rotifers are among the smallest animals on earth! They possess a ciliated corona on their head which is used to attract food particles but also to swim around freely! The single dark eye is also visible as well as the stomach filled with algae. The most visible structure is probably the v-shaped pharynx muscle! 8. Dinobryon sp. These golden algae live in colonies that form multiple branches, making them look a bit like wheat, don’t you think? Every gold bean is a single cell encased in a protective shell called the lorica. Each cell possess two unequal flagella whipping around, a short and a long one, enabling them to move around.

The Machine That Slices Tissue Thinner Than Hair!🤯 “This machine is called a Microtome. It cuts biological samples into extremely thin sections — around 3 to 5 microns thick, much thinner than a human hair. First, the tissue is embedded in wax to make it firm and stable. Then the machine slices it into ultra-thin layers so they can be examined under a microscope. At normal thickness, internal cell details would be hidden — but these slices make everything visible. Too small to see — made clear with precision.” #Science #Microscopy #DidYouKnow #LabTech #HowThingsWork

The Gram staining classic… 🧫🔬 Step by step: Crystal violet → Iodine → Decolorization → Safranin. But let’s be honest for a moment… The decolorization step is where the real art of microbiology happens. Too long? Everything turns pink. Too short? Everything stays purple. Every lab tech and microbiologist develops their own instinct for that exact moment to stop. So I’m curious 👇 What’s the best trick you learned for the decolorization step in Gram staining? • Timing? • Angle of the slide? • Drop by drop technique? • Or just pure experience? Let’s compare real lab practices in the comments. #fyp #explore #science #phd #microbiology #gramstain #microbiologylab #lablife #scientist #labtech #biotech #researchlife #laboratory #microscopy #stem #microbiologia #mikrobiyoloji

From grossing to embedding to microtomy and staining, this raspberry went through the full histology process just like a biopsy. The seeds definitely made sectioning a little more challenging, but the microscopic detail was worth it. Fun fact: raspberries are technically not a single fruit but a cluster of tiny drupelets, each with its own seed.
