    Description: Designing strong, fast, controllable, and switchable interactions between individual quantum systems is a major goal in quantum information processing. This goal, however, presents a difficult challenge because most simple quantum objects, such as photons, generally do not interact with each other. On page 887 of this issue, Dudin and Kuzmich demonstrate an interaction with exotic excitations of atomic gases, so-called Rydberg dark-state polaritons (, ), that can be turned on and off on a fast time scale and that is strong enough that the presence of just a single photon in the ensemble can prevent other photons to come nearby. Their technique provides a platform to manipulate and control the interactions between single photons. [PUBLICATION ]

    Description: To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.socscimed.2012.06.027 Byline: Philippe Calain Abstract: Media representations of suffering bodies from medical humanitarian organisations raise ethical questions, which deserve critical attention for at least three reasons. Firstly, there is a normative vacuum at the intersection of medical ethics, humanitarian ethics and the ethics of photojournalism. Secondly, the perpetuation of stereotypes of illness, famine or disasters, and their political derivations are a source of moral criticism, to which humanitarian medicine is not immune. Thirdly, accidental encounters between members of the health professions and members of the press in the humanitarian arena can result in misunderstandings and moral tension. From an ethics perspective the problem can be specified and better understood through two successive stages of reasoning. Firstly, by applying criteria of medical ethics to the concrete example of an advertising poster from a medical humanitarian organisation, I observe that media representations of suffering bodies would generally not meet ethical standards commonly applied in medical practice. Secondly, I try to identify what overriding humanitarian imperatives could outweigh such reservations. The possibility of action and the expression of moral outrage are two relevant humanitarian values which can further be spelt out through a semantic analysis of 'temoignage' (testimony). While the exact balance between the opposing sets of considerations (medical ethics and humanitarian perspectives) is difficult to appraise, awareness of all values at stake is an important initial standpoint for ethical deliberations of media representations of suffering bodies. Future pragmatic approaches to the issue should include: exploring ethical values endorsed by photojournalism, questioning current social norms about the display of suffering, collecting empirical data from past or potential victims of disasters in diverse cultural settings, and developing new canons with more creative or less problematic representations of suffering bodies than the currently accepted stereotypes.

    Description: Focusing on three children with the disorder, Aiuti and colleagues used a similar approach to that of Biffiet al., but chose a different conditioning regimen. Because corrected HSCs from patients with this syndrome are known to have a substantial selective advantage in vivo, the authors used less myeloablation but more immunosuppression to stimulate engraftment of the genetically modified immunocompetent cells. Vector copy numbers in patients' blood cells after engraftment in the MLD trial were around five times higher than those observed in trials for adrenoleukodystrophy4 and β-thalassaemia5 (around 0.2 copies of the vector after 6 years; my unpublished data). [...]the latest studies may have benefited from a higher degree of vector purity following its high-titre production.

    Description: Quantum light looks like a mysterious thing: Is it wave, or particle, or both, or neither? Since the very beginning of quantum optics, physicists have been looking for graphical ways to represent the quantum state of light in order to understand it better. One can then visualize quite surprising quantum objects, such as the so-called Schrödinger's-cat state: In classical terms, it would be an oscillation having two opposite phases at the same time, like the famous cat being both living and dead. Such exotic quantum states can now be prepared in the lab, and even better, they can be teleported--that is, destroyed in one place and recreated in another one, as shown by Lee et al. on page 330 of this issue.

    Description: Matter is generally divided into three states, namely solid, liquid, and gas. Liquid crystals form a fourth state of matter; they combine properties of liquids, such as fluidity and the ability to flow, with properties of crystalline solids, such as structural order and specific optical and electric properties. This unique combination makes liquid crystals valuable for numerous electro-optical applications, for example, in displays, cell phones, and televisions. They are also often found in living systems, for example in cell membranes made of phospholipids and in chromosomal DNA. On page 768 of this issue, Mundoor et al. (1) report a new class of liquid crystals made of long inorganic nanorods that are oriented in a perpendicular direction to the small organic molecules in which they are embedded.
