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.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
