Extended H? emission line sources from UWISH2

We present the extended source catalogue for the UKIRT Wide Field Infrared Survey for H2 (UWISH2). The survey is unbiased along the inner Galactic Plane from l ? 357° to l ? 65° and |b| ? 1.5° and covers 209 deg2. A further 42.0 and 35.5 deg2 of high dust column density regions have been targeted in Cygnus and Auriga. We have identified 33 200 individual extended H2 features. They have been classified to be associated with about 700 groups of jets and outflows, 284 individual (candidate) planetary nebulae, 30 supernova remnants and about 1300 photodissociation regions. We find a clear decline of star formation activity (traced by H2 emission from jets and photodissociation regions) with increasing distance from the Galactic Centre. About 60 per cent of the detected candidate planetary nebulae have no known counterpart and 25 per cent of all supernova remnants have detectable H2 emission associated with them

Social Factoring the Numbers with Assisted Reproduction

In early 2009 the airwaves came alive with sensational stories about Nadya Suleman, the California mother who gave birth to octuplets conceived via assisted reproductive technology. Nadya Suleman and her octuplets are vehicles through which Americans express their anxiety about race, class and gender. Expressions of concern for the health of children, the mother\u27s well-being, the future of reproductive medicine or the financial drain on taxpayers barely conceal deep impulses towards racism, sexism and classism. It is true that the public has had a longstanding fascination with multiple births and with large families. This is evidenced by a long history of media attention and film depictions of such families, both fictitious and real. However, there is a point at which fascination turns to disdain, and that occurs all too often when the parents of the children are revealed to be Other-outside of racial and class norms. This essay describes eight socio-legal anxieties that coalesce in response to Suleman\u27s story: (1) race and racial hierarchies; (2) the contingency of white privilege; (3) the nature of white motherhood; (4) the role of doctors as agents of the state; (5) reproductive technology and class; (6) bodily perfection and class markers; (7) the bounds of the traditionafla mily; and (8) geographical differences. The bounds of tolerance strain and break when individual autonomy collides with majoritarian notions of civic and moral virtue. Derision of Suleman reveals the limitations of tolerance for women who deviate from prescribed norms, including norms of choice. Suleman\u27s story is not just about multiple births, then, but about society\u27s multiple anxieties when a woman breaches the bounds of racial, class and gender expectations

Punctate vascular expression1 is a novel maize gene required for leaf pattern formation that functions downstream of the trans-acting small interfering RNA pathway

The maize (Zea mays) gene RAGGED SEEDLING2-R (RGD2-R) encodes an ARGONAUTE7-like protein required for the biogenesis of trans-acting small interfering RNA, which regulates the accumulation of AUXIN RESPONSE FACTOR3A transcripts in shoots. Although dorsiventral polarity is established in the narrow and cylindrical leaves of rgd2-R mutant plants, swapping of adaxial/abaxial epidermal identity occurs and suggests a model wherein RGD2 is required to coordinate dorsiventral and mediolateral patterning in maize leaves. Laser microdissection-microarray analyses of the rgd2-R mutant shoot apical meristem identified a novel gene, PUNCTATE VASCULAR EXPRESSION1 (PVE1), that is down-regulated in rgd2-R mutant apices. Transcripts of PVE1 provide an early molecular marker for vascular morphogenesis. Reverse genetic analyses suggest that PVE1 functions during vascular development and in mediolateral and dorsiventral patterning of maize leaves. Molecular genetic analyses of PVE1 and of rgd2-R;pve1-M2 double mutants suggest a model wherein PVE1 functions downstream of RGD2 in a pathway that intersects and interacts with the trans-acting small interfering RNA pathway
