In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent advances in the understanding of chromatin structure and dynamics are highlighted. The ways in which different modes of nucleosome reconfiguration are likely to influence each other are discussed, and some of the factors likely to regulate the dynamic properties of nucleosomes are considered.

Neurosurgery is among the newest of surgical disciplines, appearing in its modern incarnation at the dawn of twentieth century with the work of Harvey Cushing and contemporaries. Neurosurgical ethics involves challenges of manipulating anatomical locus of human identity and concerns of surgeons and patients who find themselves bound together in that venture.In recent years, neurosurgery ethics has taken on greater relevance as changes in society and technology have brought novel questions into sharp focus. Change of expanded armamentarium of techniques for interfacing with the human brain and spine— demand that we use philosophical reasoning to assess merits of technical innovations.Bioethics can be defined as systematic study of moral challenges in medicine, including moral vision, decisions, conduct, and policies related to medicine. Every surgeon should still take the Hippocratic Oath seriously and consider it a basic guide to follow good medical ethics in medical practice. It is simple and embodies three of the four modern bioethics principles – Respecting autonomy, beneficence, nonmaleficence, and justice.Spinal cord injury (SCI) is a devastating condition often affecting young and healthy individuals around the world. Currently, scientists are pressured on many fronts to develop an all-encompassing “cure” for paralysis. While scientific understanding of central nervous system (CNS) regeneration has advanced greatly in the past years, there are still many unknowns with regard to inducing successful regeneration. A more realistic approach is required if we are interested in improving the quality of life of a large proportion of the paralyzed population in a more expedient time frame.

Kalausi and The Cleansing are two films set in Kenya whose storylines touch on death and rituals among the Luo community of Kenya. Both films are in the language of Dholuo and place sharp focus on widowhood and its prevailing dilemmas and anxieties within Luo culture. It is these dilemmas and anxieties that reveal the injustices that culture metes out to women. While Kalausi engages its viewers up until the burial ceremony, The Cleansing starts after the actual burial and focuses on post-burial rituals. Thus, the two films in a way complement each other in the presentation of the injustices and intrigues that a woman faces during and after the demise of a spouse. Dramatic irony as the trope of ambiguity in the two films builds up tension, suspense and comic relief. Consequently, we examine how dramatic irony participates as a socio-cultural device of intervention in the two films. Reading the two films from this perspective, dramatic irony as a signifying trope becomes paramount in unravelling the multiplicities of interpretations evident in the critical moment of death within the Luo community. It is an extremely intricate signifying device as it plays on the contrast between reality and appearance.
