Scientists Discover Nanotech for Body’s Blood Pressure Control, Pt. 1

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 ›

Deflating Median Artery Evolution Hype, Pt. 2

On this ID the Future Eric Anderson and physician Howard Glicksman further discuss a recent Journal of Anatomy article suggesting possible evolutionary changes in humans: a persistent, prominent median artery in some people’s arms. Journalists have hyped this as evolution in action, but Anderson and Glicksman say there’s little reason to treat this as an evolutionary change, even if it’s real. And they say it’s far from clear how natural selection could select for this as an “adaptation” when its most obvious effect is to contribute to carpal tunnel syndrome and other health problems.

Deflating the Evolution Hype over Median Artery Study, Pt. 1

On this ID the Future, Eric Anderson and physician Howard Glicksman discuss a recent article in the Journal of Anatomy suggesting new microevolutionary changes in humans. Researchers say a growing number of adults have a persistent, prominent median artery in their arms, an artery that’s important in the embryonic stage but tends to disappear later on. The study was quickly hyped in the popular press with breathless headlines such as “Evolution arms us with an extra artery.” On the way to separating hype from substance, Anderson and Glicksman dive into the physiology of arteries and embryological development. Their conversation grows out of a post on the subject by Anderson at Evolution News. Oh and by the way, don’t let the Read More ›

Dr. Geoffrey Simmons On Human Design — and Re-Creating It in Robots

On this episode of ID the Future, author and physician Geoffrey Simmons joins host Andrew McDiarmid in a wide-ranging discussion of his new book, Are We Here to Re-Create Ourselves: The Convergence of Designs. From the foresight needed in the design of eyes, to our stereoscopic and redundant hearing systems, to the mysteries of design in the nervous and circulatory systems, signs of engineered design are everywhere in the human body.
