Absolute pitch (AP) is the ability to recognize a pitch, without an external reference. By surveying more than 600 musicians in music conservatories, training programs, and orchestras, we have attempted to dissect the influences of early musical training and genetics on the development of this ability. Early musical training appears to be necessary but not(More)
The development of preclinical models amenable to live animal bioactive compound screening is an attractive approach to discovering effective pharmacological therapies for disorders caused by misfolded and aggregation-prone proteins. In general, however, live animal drug screening is labor and resource intensive, and has been hampered by the lack of robust(More)
In part one of this essay, 1we provided a list of 52 prizes described as " non-Nobel " awards. The reason for choosing this term was somewhat tongue-in-cheek. The Nobel Prize has attained such a position of prestige with both scientists and the general public that other scientific awards seem to pale in comparison. This generalization is confirmed by the(More)

A resistance gene (Rph22) to barley leaf rust caused by Puccinia hordei was introgressed from the non-host species Hordeum bulbosum into cultivated barley. The H. bulbosum introgression in line ‘182Q20’ was located to chromosome 2HL using genomic in situ hybridisation (GISH). Using molecular markers it was shown to cover approximately 20 % of the genetic(More)
In cooperation with many international research workers and breeders, our team at The New Zealand Institute for Plant & Food Research Limited, New Zealand, has developed 195 lines from H. vulgare x H. bulbosum hybrids. These lines contain discrete introgressions of H. bulbosum chromatin in an H. vulgare background. The size and location of the(More)
The resistance genes Rph22 and Rym16 Hb transferred into barley from Hordeum bulbosum have been separated from a large yield penalty locus that was present in the original introgression line ‘182Q20’. The Hordeum bulbosum introgression line ‘182Q20’ possesses resistance to barley leaf rust (Rph22) and Barley mild mosaic virus (Rym16 Hb ) located on(More)
Front Cover: Victims of the Union Carbide disaster attend a weekly meeting. Executive summary The Union Carbide India Ltd. (UCIL) pesticide plant in Bhopal, which used to manufacture (among other products) the pesticide Sevin (carbaryl) gained worldwide recognition as a result of the tragic chemical disaster on the night of 2-3rd December 1984. The(More)
Intelligibility of PB word lists embedded in simultaneous masking noise was evaluated before and after fatiguing-noise exposure. Intelligibility was determined by observing the number of words correctly repeated during a shadowing task. Both the speech signal and the masking noise were filtered to a 2825-3185 Hz band. Masking-noise levels were varied from(More)
