Disharmony in the desert
Most controversies in science focus on the big questions of our existence - like the nature of matter or the fate of the Universe. But passions can run just as deep in more down-to-earth subjects too. Physics World this month reveals the remarkable story of physicists battling to understand the puzzle of "singing sand dunes" - the strange low-frequency sounds emitted by nothing more than piles of sand in the desert. The two physicists at the heart of the dispute have both come up with different explanations for the sounds, which were first reported by Marco Polo and other travellers some 700 years ago. But their rivalry has become so intense they can no longer bear to work in the same laboratory. (p25).
The doctorate in transition
The PhD used to be seen as the gold standard of scientific education, in which bright young students mastered the art of research through an intensive, three-year project. But the once-vaunted degree is now under pressure as universities - keen to draw in hefty fees and secure lucrative grants - seek to churn out to churn out ever more numbers of doctorates. Even the financial field is desperate for PhD physicists to carry out advanced data analysis and modelling tasks. John McInerney - head of physics at University College Cork - calls for the PhD to be revamped. He wants it to be extended to a minimum of four years so that students have time for a solid piece of research and can also be pick up essential project-management, business and financial skills.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
