S-acylation is a common yet poorly understood fatty acid-based post-translational modification of proteins in all eukaryotes, including plants. While exact roles for S-acylation in protein function are largely unknown the reversibility of S-acylation indicates that it is likely able to play a regulatory role. As more studies reveal the roles of S-acylation within the cell it is becoming apparent that how S-acylation affects proteins is conceptually different from other reversible modifications such as phosphorylation or ubiquitination; a new mind-set is therefore required to fully integrate these data into our knowledge of plant biology. This review aims to highlight recent advances made in the function and enzymology of S-acylation in plants, highlights current and emerging technologies for its study and suggests future avenues for investigation.

With recent advances in technology, fundamental changes have occurred in architectural flexibility methods, a great deal of experience has been gained, and many strategies and tactics have been developed in this field. However, a convergence is lacking in these experiences, methods, and tactics, which raises a need for providing a convergent approach in this regard. In this paper, it is going to propose such a model of flexibility. To do this, it is first reviewed the general concepts of flexibility, and provide a short review of its history and its main executional tactics. It is then divided its main tactics into eight main groups of: ‘open plan’, ‘pre-fabricated modules’, ‘similar spaces’, ‘extendable unit᾽, ‘attachment and detachment of adjacent units’, ‘common space between adjacent units’, ‘portable walls’, and ‘retractable furniture in a multifunctional space’. Analyzing these tactics, it is extracted the three fundamental principles of flexibility: ‘soft connection’, ‘diversity and multiplicity of spaces’, and ‘multifunctional space’. Accordingly, this paper proposes a concise rule for flexibility as: ‘soft connections between spaces’ which implies to the three principles if some special attentions are paid. Although the rule seems to be simple, the paper argumentations show that paying attention to what it implies, can produce much more flexible spaces than what is created generally. At the same time, new creative ideas along supported by new emerging technologies can enrich these simple solutions extensively.

The ophthalmic community has recently celebrated 50 years of phacoemulsification innovation, and the technology continues to evolve. Recent advances in phacoemulsification techniques and technology have improved surgical outcomes and reduced complications pre and post cataract surgery. However, opinions vary as to which techniques offer the best outcome. In an expert interview, Jennifer Loh, a board-certified ophthalmologist practicing in the south Florida area with considerable expertise in cataract surgery, discussed the most exciting developments and current controversies in phacoemulsification technology.
