An unnatural way to make natural products

From medicine to fragrances, nature provides many of the key chemical compounds needed in an endless number of pharmaceuticals and consumer products. Now, a cutting-edge technique engineered by researchers at University of ...

Space travel and your joints

A novel Henry Ford Hospital study of mice aboard a Russian spaceflight may raise an intriguing question for the astronauts of tomorrow: Could traveling in space be bad for your joints?

Engineers design solutions to tackle low-frequency noise

Low frequency noise (500 Hertz and lower), which could stem from various sources such as construction machineries and aircrafts, is a form of environmental noise problem in urban environments. Such noise transmits over long ...

Stop aging in space

Wrinkles, muscle pain, high blood pressure and a clumsy brain are all natural consequences of getting old. As our cells rust over time, a key to fighting chronic disease may be in tiny, smartly designed particles that have ...

Making lead pipes safe

Lead leaching from pipes into the water supply is a serious public health concern. And if water sources or treatment regimens are changed, the new chemistry can cause water distribution systems that were previously safe to ...

Finding the right 'dose' for solar geoengineering

One of the key misconceptions about solar geoengineering—putting aerosols into the atmosphere to reflect sunlight and reduce global warming—is that it could be used as a fix-all to reverse global warming trends and bring ...

Blood pressure

Blood pressure (BP) is the pressure (force per unit area) exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. The pressure of the circulating blood decreases as it moves away from the heart through arteries and capillaries, and toward the heart through veins. When unqualified, the term blood pressure usually refers to brachial arterial pressure: that is, in the major blood vessel of the upper left or right arm that takes blood away from the heart. Blood pressure may, however, sometimes be measured at other sites in the body, for instance at the ankle. The ratio of the blood pressure measured in the main artery at the ankle to the brachial blood pressure gives the Ankle Brachial Pressure Index (ABPI).
