mRNAs scan themselves out
In eukaryotic cells, mRNAs are transcribed in the nucleus and must then be exported across the nuclear envelope before they can be translated in the cytoplasm. Multiple factors bind to nuclear mRNAs and mediate their translocation through the nuclear pores, but it is diffi cult to observe the rapid export of individual RNA molecules in real time. Two papers now track the movements of single mRN...
متن کاملTelling sperm to sort themselves out.
Gatica et al. (2013) report the development of a new device, the sperm selection assay (SSA), for enriching the content of high-quality, functionally competent cells in a human sperm sample. The device is technically simple, but exploits a sophisticated characteristic of many motile cells and organisms—their ability to direct their movement in response to the concentration gradient of a chemica...
متن کامل3-D Gaze Scan Path by Inside-out Camera System
Measuring the 3-D gaze trajectory of a user moving dynamically in 3-D space is interesting for understanding a user’s intention and behavior. In this paper, we present a system for recovering 3-D scan path and scene structure in 3-D space on the basis of ego-motion computed from an inside-out camera. Experimental results show that the 3-D scan paths of a user moving in complex dynamic environme...
متن کاملDo people who "mature out" of drinking see themselves as more mature?
BACKGROUND Self-perceptions of adulthood during the 20s and 30s are influenced by role transitions, age-related norms, and character traits. These factors are also associated with alcohol use disorders (AUDs), which peak and subsequently decrease during this time of life. Previous developmental research has found that alcohol misuse in adolescence predicts lower reported maturity, whereas alcoh...
متن کاملPrograms that Model Themselves
Work on reeection has frequently concentrated on programming languages and operating systems. This work either involves the use of tower reeection or meta-object protocols. The subject of this paper is a diierent form of reeection that is, we believe, more powerful and fundamental than the other kinds. Self modelling is a process that has not received attention in the literature; indeed, we bel...
