If left unchecked, hypertension can lead to heart disease and, ultimately, death. Pretty scary stuff. A small increase in the diameter or radius of a blood vessel (called dilation) can lower blood … Continue reading Curd Extra Cheese Be Gouda for You?

If you regularly read this blog, you may know that the research questions that physiologists ask relate to wide range of topics—cells, tissues and organs, insects and animals, and how the environment influences all of these things. Nowhere is this more apparent than at the annual Experimental Biology meeting. This year, thousands of physiology-based research … Continue reading Of Ice Swims and Mountain Marathons (and So Much More)
Much of what we know about human health and disease comes from studies in male animals. However, researchers are finding that for blood pressure control, what’s true for male animals is not necessarily true for females. One in three adults in the U.S. has high blood pressure (hypertension) and of those, only half have their … Continue reading Beyond Mars and Venus: Three Ways Gender Can Affect your Blood Pressure
