A Thing of Beauty
A unique feature of birds is their varied and colorful plumage, replete with striking patterns. By coupling a careful mapping of distinct feather features such as pigment color, distribution, and their temporal variationwith a cellular andmolecular analysis of melanocytes, Cheng-Ming Chuong and colleagues provide a roadmap for studying feather patterning in chickens. Notably, feather patterns a...
متن کاملUnification: Not Just a Thing of Beauty
There is a strong tendency in science to opt for simpler and more unified hypotheses. A view that has often been voiced is that such qualities, though aesthetically pleasing or beautiful, are at best pragmatic considerations in matters of choosing between rival hypotheses. This essay offers a novel conception and an associated measure of unification, both of which are manifestly more than just ...
متن کاملJob-Sharing in General Practice—A Thing of Beauty
The imposition of the new General Practice contract, with all the acrimony it has engendered, has obscured another change in General Practice, which has far-reaching potential. This is the explosive rise in job-sharing seen recently, exemplified by the figures for Devon FHSA, which has seen a rise from 4 jobsharing GPs, in two years, to 28 by June, 1991 (personal communication, Devon FHSA). In ...
متن کاملCharm and Beauty Production at HERA–B
The HERA–B experiment at DESY has acquired a data-set of approximately 300,000 decays J/ψ→ l+l− during its 2002/2003 data-taking period. These data are used to analyze the production of heavy quarks in proton-nucleus interactions at a center-of-mass energy of 41.6 GeV. In this article, preliminary results of two measurements are discussed, a measurement of nuclear effects in the production of J...
متن کاملBeauty and charm results from B-factories
We present the proceedings of the lectures given at the 2008 Helmholtz International Summer School Heavy Quark Physics at the Bogoliubov Laboratory of Theoretical Physics in Dubna. In two lectures we present recent results from the existing B-factories experiments, Belle and BaBar. The discussed topics include short phenomenological motivation, experimental methods and results on B meson oscill...
