New horizons in inner space
Article Abstract:
Recent research on the interiors of carbon fullerene molecules may deepen understanding of how matter acts when confined. P.M. Ajayan and Sumio Iijima made progress in using high-energy caps as targets for making openings in fullerenes by using laser-evaporated vapor to insert microscopic bits of lead within the fullerene. This resulting nanocomposite may lead to the production of filled carbon nanostructures.

The positron probe: beams of antimatter are providing some of the most detailed images yet of defects in semiconductors
Article Abstract:
Researchers at the University of the German Federal Armed Forces have been able to use a beam of antimatter particles to search for defects in a semiconductor. They are using a microscope in which a pulsed beam of positrons is trained on the sample being investigated. Positrons entering the material are attracted to electrons and repelled by atomic nuclei.

A jump that would prove Newton wrong
Article Abstract:
A physicist proposes that a mechanical phenomenon called the modified newtonian dynamics (MOND) would make objects spontaneously jump over a very small distance, violating Newton's second law. He believes the foundations of physics have to be revised to include MOND, although other researchers are skeptical about the theory.
