Capsaicin Receptor... why peppers feel "hot"
The capsaicin receptor is a protein that, in humans, is encoded by the TRPV1 gene. The function of TRPV1 is detection and regulation of body temperature. In addition, TRPV1 provides a sensation of scalding heat and pain. TRPV1 is an element of the mammalian somatosensory system. It is a nonselective cation channel that may be activated by a variety physical and chemical stimuli. The best-known activators of TRPV1 are: temperature greater than 43 °C (109 °F); acidic conditions; capsaicin (the irritating compound in hot chili peppers); and allyl isothiocyanate, the pungent compound in mustard and wasabi. The activation of TRPV1 leads to a painful, burning sensation.

Streptococcus Bacteria
Streptococcus bacteria are an example of cocci (round bacteria) that form chains. There are currently over 50 species of Streptococcus, which are classified based on their haemolytic properties. While some species cause disease in humans, many streptococcal species are non-pathogenic and form part of the human microbiota of the mouth, skin, intestine, and upper respiratory tract.

Volvox - Colonial Algae
Volvox is a colonial chlorophyte green algae found in freshwater ponds and lakes. It consists of a hollow ball of several thousand cells, each with a chloroplast and a pair of flagella. It reproduces asexually by budding off daughter colonies which rotate in the interior until they escape.

Copper Reacts with Silver nitrate.
Copper is immersed into a 0.2M solution of silver nitrate (AgNO3).
Since copper is more reactive than silver, a single-displacement reaction occurs: Cu + AgNO3 -> Ag + Cu(NO3)2.
Formation of silver metal (Ag) is clearly visible.
As reaction progresses, the solution becomes slightly bluish due to Cu2+ ions.

Scanning electron micrograph of the stem from a stinging nettle (Urtica dioica). The large stinging hairs are hollow tubes which act like tiny glass needles. The bulb at the base of each hair contains the stinging liquid (including formic acid, histamine and acetylcholine). The tips of the glassy hairs are easily broken when brushed, which easily pierces the skin to deliver the sting. The plant and roots have been used historically in alternative medicine to treat a variety of conditions, possibly by decreasing inflammation and increasing urine output.

Insect Gyroscopes
Scanning electron micrograph of a haltere. Halteres are a pair of small club-shaped organs on the body of some flying insects (e.g. diptera). Halteres provide information about body rotations during flight. Examples of insects with halteres are houseflies, mosquitoes, gnats, and craneflies. Halteres oscillate rapidly along with the wings and operate like vibrating structure gyroscopes.

Gravitational Lensing
Gravitational lensing is the effect in which the image of a distant object is distorted by the gravitational field of an object in front of it. Initially, a distant galaxy is at the top, and the Earth at bottom. Diverging light rays from the galaxy are shown in white. If a massive object is placed in the middle, relativity predicts that the light will be bent towards the mass, in effect focusing it on Earth like a converging lens. Different arrangements produce slightly different effects. A single large mass can produce a ring with a bright central spot or multiple images forming a cross. When the lensing object is a massive cluster of galaxies, images of the more distant galaxy are likely to be smeared into thin irregular arcs.

Scale insects
Scale insects (superfamily Coccoidea) have shield-like exoskeletons (strong and rigid outer skeleton). Scale insects are plant parasites that feed on sap from the host plant. They secrete a waxy coating on their exoskeleton to protect themselves from pesticides and predators.

"Algorithm That Detects Sepsis Cut Deaths by Nearly 20 Percent"
By Sophie Bushwick on August 1, 2022
https://www.scientificamerican.com/article/algorithm-that-detects-sepsis-cut-deaths-by-nearly-20-percent/
Scanning electron micrograph (SEM). Bacteria amongst the red blood cells from the circulatory system.
When a strain of harmful bacteria gets into the bloodstream, the resulting infection is called bacterial sepsis, or bacteraemia (commonly known as blood poisoning). Multiplication of the harmful bacteria in the blood stream can cause death. When there is a high amount of toxins produced by bacteria in the blood, a septic shock may occur. Septic shock is a highly dangerous condition in which body tissues are damaged. This kind of infection can be serious, but it can usually be successfully treated with antibiotics, if caught early.

Telomeres
Computer artwork of an X and a Y chromosome. The end regions mark out the telomeres. Telomeres consist of short repeated sequences of DNA and proteins, and are looped. The loop structure prevents the end of the chromosome being eroded by enzymes present in the cell nucleus and prevents enzymes from joining two chromosomes together. Telomeres play an important role in cellular aging. As cells replicate and age the telomere steadily shrinks. When the telomere reaches a certain length the cell stops dividing and dies.

This mushroom mostly grows in association with conifers but can also grow in association with deciduous trees. The range of this mushroom is from Michigan to North Carolina, and is common in New England. As in other Amanita muscaria, the guessowii variety contains ibotenic acid and muscimol which can cause hallucinations.

Hair Raising! - "Piloerection" Close-up of fine hairs on a human arm rising and falling. Skin hairs rise in response to stimuli including cold, fear and awe. Technically known as piloerection, it is produced by the contraction of a small muscle (the arrector pili) at the base of each hair. © SPL Motion / Science Source ScienceSource.com ID# SS277212 Click on the link for this clip and for more science and medical content. https://www.sciencesource.com/archive/Video/Arm-hairs-rising-and-falling-SS277212.html Music: "Also sprach Zarathustra" by Strauss Kevin MacLeod (Creative Commons Attribution 3.0 Unported license) #piloerection #hair #hairraising #fear #awe #chill #cold #goosebumps #goosepimples #dermatology #dermatologist #AlsosprachZarathustra #2001spaceodyssey #spaceodyssey #pilomotorreflex #reflex #stimuli #armhair #arrectorpili #sciart #scienceart #alwayslearning #scienceteacher #science #homeschoolscience #stockvideo #sciencevideo #biology #biologyteacher #biologyclass
Flame Test Click on the link for these clips and images and for more science and medical content. https://www.sciencesource.com/CS.aspx?VP3=DamView&VBID=2OPVHKG5GURH3 A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions. The color of the flame is determined by the element's emission spectrum which is characteristic to that element. Therefore, flame tests can be used as an analytic procedure for identifying elements.

CYTOSKELETON INSIDE A CELL Animation of the inside of a typical human cell, showing the components of its supportive cytoskeleton. The main supportive structures are thin microfilaments made of the protein actin (white), and larger microtubules, made from the protein tubulin (blue-green blobs). Microtubules are important in maintaining the cell's shape, helping its movement and motility, and providing a framework through which components can be moved around the cell. One way this occurs is through the motor protein kinesin (red). A microtubule grows to where a cellular component is required. The kinesin binds to a transport vesicle containing the component protein, and the head end of the kinesin binds to the microtubule. It then 'walks' along the microtubule from the center to the edge of the cell, carrying the vesicle's content to where it is required. The growth of the microtubules is controlled by the centrosome, a central body in the cell. This contains two centrioles (orange) made of tubulin, surrounded by a protein body.

Photosynthesis in Cyanobacteria Time lapse microscope footage of a mat of cyanobacteria bubbling as it produces oxygen through photosynthesis. Photosynthesis is the process by which organisms use the energy of sunlight to turn atmospheric carbon dioxide into energy-rich sugars, releasing oxygen as a waste product. Cyanobacteria were the first photosynthetic organisms on Earth, and were responsible for oxygenating the atmosphere some 2.3 billion years ago. It is thought that the chloroplasts found in plant cells derived from symbiotic cyanobacteria that lived within the cells of the ancestors of plants and algae. © Francis Chee / Science Source ScienceSource.com image ID# SS278049 Click on the link in our bio for this image and for more science and medical images (and video!).
