The forms, functions, and organization of sounds and utterances are generally the focus of speech communication research; little is known, however, about how the silence between speaker turns shades the meaning of the surrounding talk. We use an experimental protocol to test whether listeners’ perception of trouble in interaction (e.g., disagreement or unwillingness) varies when prosodic cues a...

Silence is a newly isolated siphophage that infects Bacillus megaterium, a soil bacterium that is used readily in research and commercial applications. A study of B. megaterium phage Silence will enhance our knowledge of the diversity of Bacillus phages. Here, we describe the complete genome sequence and annotated features of Silence.

" Like all good memoirs it has not been emasculated by considerations of good taste. " That was Peter Medawar's verdict on The Double Helix, Jim Watson's ebullient succès de scandale. Watson's exuberant style, let it be said right away, is not Maurice Wilkins's. He and Francis Crick were outraged by Watson's account — now a modern classic, at number seven in the American Modern Library's roll o...

Recent findings indicate that heterochromatin serves as a molecular sink for factors involved in chromatin-mediated repression of gene expression; long-range interactions that position a euchromatic gene near a heterochromatin domain influence its susceptibility to transcriptional silencing.

The large genomes of higher eukaryotes suggest a need for stable packaging, particularly as most of the DNA does not code for proteins, and much consists of repetitious sequences, including remnants of invading retrotransposons, transposable elements and the like. Cytological studies first demonstrated that much of the repetitous DNA is packaged in a condensed form referred to as heterochromati...

How does auditory cortex respond to silence? In this issue of Neuron, show that activity in macaque auditory cortex is highly structured even in the absence of sensory stimuli. These data reveal a close link between spontaneous neural activity and the functional organization of auditory cortex.

Although the discovery of genomic imprinting dates back more than two decades, its significance for both disease pathogenesis and evolutionary theory is only now emerging. However, its effects had been observed for much longer, and if biologists had been influenced less by prevailing orthodoxies, they might have stumbled on it sooner. Mule breeders encountered the phenomenon three millennia ago...

2255-4971 On March 1, Prof. Dr. Eduardo Álvaro Vieira passed away. n 1971, he was the first orthopedics and traumatology resient of the Sorocaba Medical School of the Pontifical Catholic niversity of São Paulo (PUC-SP), of which he became a proessor in the same year. He was a pupil of Professor Luiz ustavo Wertheimer, became interested in knee surgery and onducted extensive anatomical studies o...
