Making the cut.
t was conceived after a yogurt company in 2007 identified an unexpected defense mechanism that its bacteria use to fight off viruses. A birth announcement came in 2012, followed by crucial first steps in 2013 and a massive growth spurt last year. Now, it has matured into a molecular marvel, and much of the world—not just biologists—is taking notice of the genome-editing method CRISPR, Science’s...
متن کاملMaking the cut
'Deliberate self-harm', 'self-mutilation' and 'self-injury' are just some of the terms used to describe one of the most prominent issues in British mental health policy in recent years. This article demonstrates that contemporary literature on 'self-harm' produces this phenomenon (to varying extents) around two key characteristics. First, this behaviour is predominantly performed by those ident...
متن کاملMaking the cut: lattice kirigami rules.
In this Letter we explore and develop a simple set of rules that apply to cutting, pasting, and folding honeycomb lattices. We consider origami-like structures that are extrinsically flat away from zero-dimensional sources of Gaussian curvature and one-dimensional sources of mean curvature, and our cutting and pasting rules maintain the intrinsic bond lengths on both the lattice and its dual la...
متن کاملMaking the cut: analytical and empirical bioethics.
This issue of the journal includes papers across both analytical and empirical schools within bioethics. In his feature article, ‘The kindest cut? Surgical castration, sex offenders and coercive offers’, John McMillan asks whether surgical castration can be ethically provided as medical treatment for sex offenders (see page 583, Editor’s choice). While surgical castration has previously been av...
متن کاملCytokinesis: Placing and Making the Final Cut
Cytokinesis is the process by which cells physically separate after the duplication and spatial segregation of the genetic material. A number of general principles apply to this process. First the microtubule cytoskeleton plays an important role in the choice and positioning of the division site. Once the site is chosen, the local assembly of the actomyosin contractile ring remodels the plasma ...
