New Challenges and Old Problems

New Insights to Old Problems

From the history of the θ-τ puzzle and the discovery of parity non-conservation in 1956, we review the current status of discrete symmetry violations in the weak interaction. Possible origin of these symmetry violations are discussed. PACS: 11.30.Er, 12.15.Ff, 14.60.Pq

Children and computers: new technology--old concerns.

Computer technology has ushered in a new era of mass media, bringing with it great promise and great concerns about the effect on children's development and well-being. Although we tend to see these issues as being new, similar promises and concerns have accompanied each new wave of media technology throughout the past century: films in the early 1900s, radio in the 1920s, and television in the...

Revitalized old technology spurs new interest, applications

August 01, 2007 | Musculoskeletal Imaging [1], Vendors [2] Although the roots of traditional geometric x-ray tomography date back to the 1930s, the technique was not practical at that time because image receptors could not provide large-area dynamic scanning. The technique, renamed tomosynthesis in the 1970s, acquired only one imaging section at a time, requiring additional time and radiation d...

Capsule Endoscopy: New Technology, Old Complication

Wireless capsule endoscopy is a new tool in the armamentarium of the gastroenterologist to evaluate the small bowel non-invasively. It allows improved diagnostic yield with low complication rates relative to traditional modalities. But this new technology has its own set of complications, some which can lead to significant morbidity. Here, we present a case of complete small bowel obstruction f...
