Experiments challenge fundamental understanding of electromagnetism

A cornerstone of physics, quantum electrodynamics, may require some updates if the findings of recent experiments on highly charged ions are confirmed.

Mix masters: Scientists image the molecular structure of polymer blends

Using an enhanced form of 'chemical microscopy', researchers have shown that they can peer into the structure of blended polymers, resolving details of the molecular arrangement at sub-micrometer levels. The capability has important implications for the design of industrially important polymers like the polyethylene blends used to repair aging waterlines.

Graphite experiment shines new light on giant planets, white dwarfs and laser-driven fusion

Researchers are dealing with unexpected results of an experiment with strongly heated graphite (up to 17,000 Kelvin). The findings may pose a new problem for physicists working in laser-driven nuclear fusion and may also lead astrophysicists to revise our understanding of the life cycle of giant planets and stars.
