Each October, the Nobel Prizes celebrate a handful of groundbreaking scientific achievements. For George de Hevesy, the 1943 Nobel Laureate in chemistry who discovered radioactive tracers, that place ...

Fluorine is critical for biomedicine. This element can help drug compounds be more potent and last longer in the body, and ...

In an advance for medical imaging, scientists from University of North Carolina Lineberger Comprehensive Cancer Center have discovered a method for creating radioactive tracers to better track ...

During a nuclear stress test, you’ll be injected with a radioactive dye called a tracer. Some of this tracer will remain in your system for a time after the test. A nuclear stress test is a type of ...

A patient checks into the hospital with difficulty breathing. Is inflammation to blame? How can physicians visualize areas of inflammation in the respiratory system in order to choose the best course ...

Coronary plaques are blockages that cause narrowing and hardening of the heart's blood vessels, often causing angina (chest pain). When plaques rupture, they can lead to blood clot formation which ...

AT the beginning of this century, one of the facts most intriguing to chemists was the impossibility of concentrating some of the radioactive elements. Radium D, for example, a substance well ...

Medical imaging has experienced tremendous growth since the discovery of X-rays: the x-ray-based CT scanner, advances in positron emission tomographic (PET) imaging, the development of single photon ...

RADIOACTIVE TRACERS have been used to study the fuel distribution among individual cylinders in two modern V-8 engines. Individual fuel components (both hydrocarbons and fuel additives) were "tagged" ...

THIS note gives a brief account of a radioactive tracer technique for the detection and estimation of the short-lived aliphatic free radicals; it is being used in both dynamic and static experiments.

“Probably the most useful tool for research since the discovery of the microscope” was described in detail last week by Dr. Joseph G. Hamilton of the University of California. The tool he referred to ...
