Have you met the blood-drawing robot phlebotomist?
Drawing blood should be a routine procedure. Unfortunately complications can be common either in the elderly, who may have a compromised vasculature, or in children who are literally scared out of their minds. A startup based in Mountain View, California aims to replace your friendly phlebotomist with a robot. If this new device can gain patient confidence and perform well under ideal conditions, perhaps it can also be of service in more demanding conditions as well. Read more: Meet your new…
Daphnia, Daphnia, How do I Love Thee?
Let Me Count The Ways (of Measuring Your Heart Rate!) Valentine's Day does not have to go unnoticed in our high school biology classes! We might not discuss the emotional affairs of the heart, but we can definitely discuss the physiology of the heart! Each year, during the week of Valentine's Day, I take my biology students to the lab to measure the heart rate in the crustacean, Daphnia. Since Daphnia is an ectotherm, its heart rate will vary with changes in its body temperature. (I also…
