Catching Some Zs A New Protein for Spatial Regulation of Bacterial Cytokinesis
Prior to its duplication, the bacterial nucleoid exerts local negative control over assembly of the cytokinetic Z ring to prevent potential cutting of the chromosome. In this issue of Cell, Wu and Errington show that a specific nucleoid-associated protein mediates this nucleoid occlusion effect, providing the first mechanistic insight into this key spatial regulatory system.
متن کاملShedding some light on catching in the dark: perceptual mechanisms for catching fly balls.
To catch a lofted ball, a catcher must pick up information that guides locomotion to where the ball will land. The acceleration of tangent of the elevation angle of the ball (AT) has received empirical support as a possible source of this information. Little, however, has been said about how the information is detected. Do catchers fixate on a stationary point, or do they track the ball with th...
متن کاملCatching Liars.
While trying to think of an interesting way to introduce this major review of the field of lie detection, I did what lots of people do these days. I typed ‘‘catching liars’’ into the Google search bar and up came 305,000 results in .17 seconds. The first page was ‘‘10 ways to catch a liar’’ from WebMD. The essay featured J.J. Newberry, a trained federal agent purported to be skilled at detectin...
متن کاملEye catching
" Scientists for the first time have used gene therapy to dramatically improve sight in people with a rare form of blindness, a development that experts called a major advance for the experimental technique, " said the Gainsville Sun in Florida, the state in which the results were announced at a meeting last month. It's a story that excited many news editors with a number of angles to heighten ...
متن کاملCatching Metaphors
Metaphors are ubiquitous in language and developing methods to identify and deal with metaphors is an open problem in Natural Language Processing (NLP). In this paper we describe results from using a maximum entropy (ME) classifier to identify metaphors. Using the Wall Street Journal (WSJ) corpus, we annotated all the verbal targets associated with a set of frames which includes frames of spati...
