Remember cold fusion? Most scientists believe the dream of generating an abundance of cheap energy by fusing two atomic nuclei at room temperature is dead after a 1989 tabletop experiment couldn't be repeated and its results were questioned.

Tom Meyer, a chemistry professor at the University of North Carolina at Chapel Hill, is one of them.

Events taking place the week of Sept. 21 in the Research Triangle area that are open to the public:

Why global health matters to North Carolina

Presented by the Center for Strategic & International Studies Global Health Policy Center and the Triangle Global Health Consortium, the forum will highlight how North Carolina generates knowledge, skills, jobs and partnerships essential to U.S. leadership in global health.

Machines that scan luggage at airports and look inside the body still bear the imprint of Wilhelm Roentgen, the German physics professor who stumbled upon X-rays 114 years ago.

That's because little has changed in the way X-rays are generated: Today's most sophisticated CT scanners produce detailed, three-dimensional images of the heart or the brain with the help of vaccuum tubes that are technologically similar to the one Roentgen used for the iconic image of his wife's hand with rings.
