Transmission Electron Micrograph (TEM) of a single strand of Deoxyribonucleic acid (DNA). DNA is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. DNA is comprised Stock Photo

Transmission Electron Micrograph (TEM) of the human respiratory syncytial virus pathogen. Human respiratory syncytial virus (HRSV) is a negative-sense, single-stranded RNA virus of the family Pneumoviridae. Its name comes from the fact that F proteins on the surface of the virus cause the cell membranes on nearby cells to merge, forming syncytia. HRSV is a syncytial (multinucleated cell that can result from multiple cell fusions of uninuclear cells) virus that causes respiratory tract infections. It is a major cause of lower respiratory tract infections and hospital visits during infancy and c Stock Photo

The Arming sword (Knightly sword) was the most widespread type of sword in the European High Middle Ages. It was a straight, double-edged weapon with a single-handed cruciform hilt and a blade length of about 28 to 31 inches. The type is frequently depicted in period artwork, and numerous examples have been preserved archeologically. The high medieval sword of the Romanesque period (10th-13th centuries) develops gradually from the Carolingian sword (spatha) of the 9th century.

RM2BE0H4R–Scanning Electron Micrograph (SEM) showing Giardia muris protozoan settled atop intestinal mucosal villi, adhering itself to the microvillous border of intestinal epithelial cells. Each small circular profile under the protozoan represents the rounded tip of a single microvillous, and it is estimated that 2000 to 3000 microvilli cover the surface of a single intestinal epithelial cell. The protozoan Giardia causes the diarrheal disease called giardiasis.

It has a length of well over 2,000 feet. In 1928, in order to improve navigation in the Harlem River, all of the masonry arches of the central part of the bridge that spanned the river were demolished and replaced with a single steel arch of about 450 feet. Of the masonry

O'Donnell on Whirlwind, Cheyenne Frontier Days, 1911. Cowboys of the American West developed a personal culture of their own, a blend of frontier and Victorian values that even retained vestiges of chivalry. Such hazardous work in isolated conditions also bred a tradition of self-dependence and individualism, with great value put on personal honesty, exemplified in songs and poetry. The average cowboy earned approximately a dollar a day, plus food, and, when near the home ranch, a bed in the bunkhouse, usually a barracks-like building with a single open room.

RMG169MK–Marey's fixed-plate chronophotography machine, with ten slit-disk that acts as a shutter, on the ground is the sensitized-plate holder, 1883 model. The fixed plate camera was equipped with a timed shutter that was able to combine on a single plate several successive images of a single movement. In order to allow shooting in different positions, he placed the camera inside a large wooden cabin that ran on rails. Étienne-Jules Marey (March 5, 1830 - May 21, 1904) was a French scientist, physiologist and chronophotographer. He started by studying blood circulation in the human body. Then shifted

The Middle East respiratory syndrome coronavirus (MERS-CoV), also termed EMC/2012 (HCoV-EMC/2012), is positive-sense, single-stranded RNA novel species of the genus Betacoronavirus. First called novel coronavirus 2012 or simply novel coronavirus, it was first reported in 2012 after genome sequencing of a virus isolated from sputum samples from patients who fell ill in a 2012 outbreak of a new flu.

Scanning Elctron Micrograph (SEM) of Pseudomonas aeruginosa, a versatile gram-negative bacterium that grows in soil, marshes, and coastal marine habitats, as well as on plant and animal tissues. Pseudomonas aeruginosa is rod-shaped bacterium that can cause disease in plants and animals, including humans. A species of considerable medical importance, P. aeruginosa is a multidrug resistant pathogen recognised for its ubiquity, its intrinsically advanced antibiotic resistance mechanisms, and its association with serious illnesses, hospital-acquired infections such as ventilator-associated pneumon Stock Photo

Of importance is the sticky-looking substance woven between the round cocci bacteria, which was composed of polysaccharides, and is known as biofilm. This biofilm has been found to protect the bacteria that secrete the substance from attacks by antimicrobial agents such as antibiotics.
