The Physical Characteristics of Urine

Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology The urinary system’s ability to filter the blood resides in about 2 to 3 million tufts of specialized capillaries—the glomeruli—distributed more or less equally between the two kidneys. Because the glomeruli filter the blood based mostly on particle size, large elements like blood cells, platelets, antibodies, … Continue reading The Physical Characteristics of Urine

Minerals That Can Be Found in Food

Source: https://www.hemophiliafed.org/news-stories/2010/11/essential-nutrients-vitamins-minerals/ OpenStax Anatomy and Physiology Minerals in food are inorganic compounds that work with other nutrients to ensure the body functions properly. Minerals cannot be made in the body; they come from the diet. The amount of minerals in the body is small—only 4 percent of the total body mass—and most of that consists … Continue reading Minerals That Can Be Found in Food

The Fluorescence Microscopes

(a) A direct immunofluorescent stain is used to visualize Neisseria gonorrhoeae, the bacterium that causes gonorrhea. (b) An indirect immunofluorescent stain is used to visualize larvae of Schistosoma mansoni, a parasitic worm that causes schistosomiasis, an intestinal disease common in the tropics. (c) In direct immunofluorescence, the stain is absorbed by a primary antibody, which … Continue reading The Fluorescence Microscopes

It can perform well over a trillion logical operations per second. It’s compact, fitting neatly inside the skull. It uses as much power as a light bulb, and it has … Continue reading UC San Diego Neurobiologist Part of $2 million Project to Study Brain, Motor-skill Learning

In Some Children with Autism, “Social” and “Visual” Neural Circuits Don’t Quite Connect

Source: https://autismawarenesscentre.com/the-positives-of-autism/ By: Scott Lafee Among the first and most-documented symptoms of autism spectrum disorder (ASD) is a child’s aversion to interaction with others. Specifically, they appear uninterested in social activities and stimuli that would normally attract a young child’s attention, such as watching other children play, sing or dance. In a new study, published … Continue reading In Some Children with Autism, “Social” and “Visual” Neural Circuits Don’t Quite Connect
