On this ID the Future, physician Howard Glicksman and host Eric Anderson dive deeper into the body’s exquisite blood pressure control system, cueing off a new discovery described at Science Daily as uncovering “the location of natural blood-pressure barometers inside our bodies that have eluded scientists for more than 60 years.” According to the primary research paper at Circulation Research, “Renin-expressing cells are essential for survival, perfected throughout evolution to maintain blood pressure (BP) and fluid-electrolyte homeostasis.” How did evolution perfect the system? How did it originate the system? The paper never says. The mention of evolution appears to be little more than a de rigueur genuflection before the reigning paradigm of blind evolution. What is bearing actual fruit, according to Glicksman Read More ›

On this ID the Future, physician and Evolution News writer Howard Glicksman discusses an exciting new discovery by researchers at the University of Virginia School of Medicine, described at Science Daily as uncovering “the location of natural blood-pressure barometers inside our bodies that have eluded scientists for more than 60 years.” As the article reports, “The existence of a pressure sensor inside renin cells was first proposed back in 1957. It made sense: The cells had to know when to release renin, a hormone that helps regulate blood pressure. But even though scientists suspected this cellular barometer had to exist, they couldn’t tell what it was and whether it was located in renin cells or surrounding cells.” Dr. Glicksman and Read More ›
