Diurnal Variations in Temperature and work potential This image comes to us from Souissi  (2007).  These authors wished to test the hypothesis that the time of day affects the performance a short, all out test of anerobic capacity of skeletal muscles.  This YouTube video gives an idea of how this test works. In infections like… Continue reading Antipyretics

"Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories. Changes in the structure and functioning of many millions of interconnected nerve cells allow combined inputs to be stored… Continue reading Sense of Smell

AZ 6-12 Science PS4: Waves and Their Applications in Technologies for Information Transfer This one has been a favorite of mine since I was about ten years old.  Physiology and anatomy of color vision leads us to the conclusion that color is an illusion of our retina and processing by our brains.  I was subbing… Continue reading cheap multispectral imaging

Merkel  "Touch Cells" This blog is a simplified version of a review on Merkel touch cells that was written for PhD level scientists.  Part of the AZ science requirements for middle school kids are good and kind of crazy at the same time.  They are good because they introduce kids to just how mind boggling… Continue reading AZ life sciences Merkel cells
