Watch the vacuole form and wait until the end... Epistylis ciliate. Close-up differential interference contrast (DIC) light microscopy footage of a specimen of the ciliate protozoan Epistylis, obtained from activated sludge. Epistylis is a genus of sessile single-celled protozoans, with a long stalk and a flattened head. At the top of the head is the mouth, surrounded by many fine cilia hairs. These create a vortex in the surrounding water, washing food particles into the mouth. Activated sludge is the term for a process that treats sewage and industrial waste water using bacteria and protozoa. © Frank Fox / Science Source ScienceSource.com ID# SS282940 Click on the following link for this clip and more science and medical content. https://www.sciencesource.com/archive/Epistylis-ciliate--light-microscopy-SS282940.html #ciliate #ciliata #Epistylis #protozoan #protozoa #sludge #singlecelled #singlecelledorganism #cilia #activatedsludge #wastewater #microscopy #lightmicroscopy #lightmicroscope #biology #biologist #ecology #sciencevideo #nature #microbiology #microbiologist #sewage #vacuole #stockvideo #protozoans #scienceteacher #biologyteacher #alwayslearning #homeschoolscience #differentialinterferencecontrast

Congratulations to Emmanuelle Charpentier and Jennifer Doudna for winning the Nobel Prize in Chemistry for their work developing the CRISPR–Cas9 gene-editing tools. The CRISPR-Cas protein is used in genetic engineering to cut DNA (deoxyribonucleic acid, blue) at a specific site.

It is based on a simplified version of the bacterial CRISPR-Cas9 antiviral defense system. By delivering the Cas9 nuclease combined with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added. CRISPR stands for "clustered regularly interspaced short palindromic repeats," which refers to the unusual pattern of sequences found in CRISPR DNA. They are composed of small pieces of viral DNA harvested from viruses that attacked in the past, separated by a distinctive repeated sequence used to create the archive. New sequences are added at the beginning of this collection allowing scientists to read the CRISPR sequence and see a history of viruses that have attacked the bacterial population in the past. Bacteria use CRISPR sequences, stored in their genome, to identify attacking viruses. Cas proteins (short for "CRISPR-associated proteins") use the viral information to fight the viruses if they try to infect the bacteria again. It carries a RNA transcript of the CRISPR sequence and searches through the cell for matching viral DNA from an infection. If it finds viral DNA, it unwinds it and mobilizes nucleases to cut it up. It is this process that has been utilized to create the gene editing techniques. #crispr #crisprcas #nobel #nobelprize #chem

Tardigrade Tuesday... Tun Edition (time lapse) Light microscopy of a water bear dehydrating to enter a dormant state, known as a tun. Water bears (or tardigrades) are tiny invertebrates that live in aquatic and semi-aquatic habitats such as lichen and damp moss. In dry conditions, they can enter a cryptobiotic state of desiccation, in which they can survive for up to a decade. They are found throughout the world, including regions of extreme temperature, such as hot springs, and extreme pressure, such as deep underwater. Water bears can also survive the high levels of radiation and vacuum of space. © Sinclair Stammers / Cwmni Da / Science Source ScienceSource.com image ID# SS248876 https://www.sciencesource.com/archive/Water-bear--light-microscopy-SS248876.html #tardigrade #waterbear #waterbears #tardigrades #tardigradesofinstagram #invertebrate #extremophiles #microbiology #nature #biology #science #mosspiglet #lightmicroscopy #microscopy #sciencenerd #startrekdiscovery #stockvideo #sciart #scienceart #tardigradetuesday #alwayslearning #scienceteacher #biologyteacher #macro #microbiologist #instagood #macro #timelapse #timelapsevideo #timelapsephotography

Slime Mold

Despite its name, a slime mold is not a fungus, instead being an amoeba-like protozoan. When food is abundant it exists as single cells like other amoebae, but when food is scarce the cells aggregate and form a large macroscopic body called a plasmodium, which contains many nuclei. This plasmodium is active, following chemical cues to find the bacteria and other micro-organisms on which it feeds. When it has exhausted its food supply it forms its reproductive stage, hardening into spore-bearing sporangia, which resemble fungi or molds. The spores are dispersed by wind or insects, and can remain dormant for many years before developing into new single-celled amoeba.

Entamoeba histolytica protozoan (parasite) Light microscope video of a single Entamoeba histolytica protozoan. E. histolytica is a parasite that causes amoebic dysentery in humans. Seen here is the active trophozoite form of the parasite, which lives in the human intestines, causing ulceration and symptoms including diarrhea, cramps, fever and weight loss. If untreated, the amoeba can move to the liver and other organs, and the infection can prove fatal in some cases. The disease is endemic in regions with poor sanitation. The parasites are passed in feces, and can survive outside the body as long-lasting cysts, which revert to the active trophozoite stage when ingested. Proper hygiene aids prevention of the disease. Treatment is with antimicrobial drugs. The trophozoites can reach 20 microns in diameter. This is the Pavia Biopsy (PVB) strain. © Sinclair Stammers / London School of Hygiene & Tropical Medicine / Science Source ScienceSource.com ID# SS250510 https://www.sciencesource.com/archive/Entamoeba-histolytica-parasite-SS250510.html #entamoeba #entamoebahistolytica #parasite #parasites #amoeba #amoebic #amoebicdysentery #dysentery #protozoa #protozoan #trophozoites #trophozoite #paviabiopsy #paviabiopsystrain #pvb #lm #lightmicroscopy #microscopy #microscope #sciart #sciencevideo #video #scienceart #stockvideo #scienceteacher #biology #biologyteacher #alwayslearning #homeschoolscience #amoebozoan

Tardigrade Tuesday! Tardigrade (Hypsibius dujardini) walking under a microscope. Tardigrades are commonly known as water bears or moss piglets. They are found in practically every habitat on Earth, from hot springs to beneath ice sheets, and are renowned for their toughness. Experiments have shown they can survive being frozen to nearly absolute zero and heated to 150 degrees Celsius. They have survived pressures of more than 6000 atmospheres, and have survived after prolonged exposure to the vacuum and radiation found in space. In unfavorable conditions they can dehydrate to 1% of their normal water content and remain alive in stasis for over a decade. In more normal conditions, they prefer moist environments where they feed on algae and bacteria. This tardigrade is often used as a model organism in biological research, and its genome is being sequenced. © Sinclair Stammers / Science Source ScienceSource.com image ID# SS218411 https://www.sciencesource.com/archive/Tardigrade--microscopy-SS218411.html #tardigrade #waterbear #waterbears #tardigrades #tardigradesofinstagram #invertebrate #extremophiles #microbiology #nature #biology #wow #cute #science #amazing #mosspiglet #derp #alwayslearning #scienceteacher #biologyteacher #biology #microscopy #tardigradetuesday #startrekdiscovery #stockvideo #tardigradesofinstagram #scienceart #sciart #hypsibiusdujardini #hypsibius #lightmicroscopy

Slime Mold in Action! Time-lapse video of a slime mold forming reproductive sporangia. Despite its name, a slime mold is not a fungus, instead it is an amoeba-like protozoan. After the feeding phase, slime molds develop tall fungus-like sporangia, which contain its reproductive spores. These spores are released as the sporangia dry out, and are dispersed by wind and insects. The spores can remain dormant for years, germinating when conditions are right and forming new single-celled amoeba. These amoeba feed on bacteria, but when food is scarce the individual cells join together, forming a multinucleate body called a plasmodium. This plasmodium moves around hunting bacteria and other microorganisms. © Francis Chee / Science Source ScienceSource.com ID# SS265548 #slimemold #slimemolds #mold #molds #slime #spore #spores #sporangia #protozoa #protozoan #plasmodia #plasmodium #zoology #microbiology #biology #biologyteacher #macro #timelapse #sciart #scienceart #alwayslearning #scienceteacher #science #homeschoolscience #stockvideo #sciencevideo #biologyvideo #oddlysatisfying #satisfying #fun #slimevid #slimey

Brugia malayi, cause of elephantiasis Light microscopy of the parasitic nematode worm Brugia malayi, cause of elephantiasis in humans. Elephantiasis (lymphatic filariasis) is a disease that causes massive and debilitating swelling and thickening of the skin, particularly in the legs, giving them the appearance of elephants' legs. It affects more than 100 million people, making it one of the most common causes of disability in the world. The symptoms are produced when the worms invade the lymphatic system, blocking the normal flow of lymph fluid and causing edema in the lower body. Brugia malayi is transmitted by the bites of tropical mosquitoes, including Aedes and Anopheles sp. Treatment is with drugs such as diethylcarbamazine. © Sinclair Stammers / Science Source ScienceSource.com ID# SS27437 #brugiamalayi #brugia #elephantiasis #lymphaticfilariasis #filariasis #nematode #nematodes #worm #worms #lightmicroscopy #microscopy #disease #parasite #parasites #parasitic #edema #oedema #mosquitoes #mosquito #diethylcarbamazine #aedes #anopheles #elephantiasistropica # wuchereriabancrofti # wuchereria #brugiatimori #stockvideo #sciencevideo #premed #tropicaldisease #tropicaldiseases #biology
