Fibers keep cilia regular A ctin fi bers and microtubules help cilia coordinate the direction and sequence of their beating, Werner et al. show. At fi rst, the multiple cilia on an embryonic cell are a bit like the musicians in a garage band, each doing its own thing. But over time the fi laments turn so that they all beat in the same direction. They also coordinate their timing, so that the ci...

Youth strengths are as important to consider as deficits in understanding developmental outcomes and thus are an important component of psychoeducational assessment. Latino/as are understudied with regard to strength-based constructs, although cultural and socioeconomic factors may be related to differences in Latino/a parents’ views of their children’s strengths and school experiences. The Beh...

We prove the Bers density conjecture for singly degenerate Kleinian surface groups without parabolics.

Poly(hexano-6-lactone) (PCL2) ®bers were degraded under environmental conditions, including soil burial, seawater exposure, and activated sludge exposure. The extent of degradation was examined by weight loss, loss of mechanical properties, such a tensile strength and ultimate elongation decreases, and visual observations by scanning electron microscopy. The rate of degradation was found to dep...

Today scientists are producing large volumes of data that they wish to explore and visualize. In this paper we describe a system that combines range-based queries with fast lookup to allow a scientist to quickly and efficiently ask “what if?” questions. Unique to our system is the ability to perform “cumulative queries” that work on both an intraand inter-time step basis. The results of such qu...

Facebook has established itself as one of the major players in social networking, claiming that it helps members connect and share with the people in their lives. But what if the people you want to connect and share with are your artistic collaborators? Can Facebook be used creatively, as a collaborative artistic environment? This paper explores the creative use of Facebook as a tool for creati...

Fibul in-5 for youthful skin A loss of tissue elasticity leads to wrinkles and more serious age-related problems, such as emphysema and vascular defects. On page 1061, Hirai et al. report that youthful elastic fi bers are assembled by an extracellular matrix protein that slips away with age. Mice that lack this matrix protein, called fi bulin-5, have loose, wrinkled skin, vascular abnormalities...
