In nature the aerial trace of pheromone used by male moths to find a female appears as a train of discontinuous pulses separated by gaps among a complex odorant background constituted of plant volatiles. We investigated the effect of such

Probing the mechanical architecture of the vertebrate meiotic spindle.

Takeshi Itabashi et al.

Nature methods, 6(2), 167-172 (2009-01-20)

Accurate chromosome segregation during meiosis depends on the assembly of a microtubule-based spindle of proper shape and size. Current models for spindle-size control focus on reaction diffusion-based chemical regulation and balance in activities of motor proteins. Although several molecular perturbations

A versatile low temperature synthetic route to Zintl phase precursors: Na4Si4, Na4Ge4 and K4Ge4 as examples.

Xuchu Ma et al.

Dalton transactions (Cambridge, England : 2003), (46)(46), 10250-10255 (2009-11-19)

Na(4)Si(4) and Na(4)Ge(4) are ideal chemical precursors for inorganic clathrate structures, clusters, and nanocrystals. The monoclinic Zintl phases, Na(4)Si(4) and Na(4)Ge(4), contain isolated homo-tetrahedranide [Si(4)](4-) and [Ge(4)](4-) clusters surrounded by alkali metal cations. In this study, a simple scalable route

Diverse two-dimensional input functions control bacterial sugar genes.

Shai Kaplan et al.

Molecular cell, 29(6), 786-792 (2008-04-01)

Cells respond to signals by regulating gene expression. The relation between the level of input signals and the transcription rate of the gene is called the gene's input function. Because most genes are regulated by more than one signal, the

Adenosine induces growth-cone turning of sensory neurons.

Benjamin Grau et al.

Purinergic signalling, 4(4), 357-364 (2008-09-09)

The formation of appropriate connections between neurons and their specific targets is an essential step during development and repair of the nervous system. Growth cones are located at the leading edges of the growing neurites and respond to environmental cues
