An experiment at SLAC's X-ray laser has revealed in atomic detail how a hypertension drug binds to a cellular receptor that plays a key role in regulating blood pressure.
Image - This photo shows a medical device used to monitor blood pressure. In a study at SLAC's Linac Coherent Light Source X-ray laser, researchers studied how a hypertension drug binds to a cellular receptor known as an angiotensin II type 1 receptor.
