Brutal Savages in an Unknown Island: Conspiracy, Mimetic Desire, Sacrificial Violence, and the Scapegoating of Irishness in Late Colonial New South Wales, 1860 – 1880

Information regarding the incident that took place in the picturesque beachside Illawarra suburb of Bellambi during the early hours of the morning on Saturday, the 26th of May, 1877, remains scarce, although it can be safely assumed that the witnesses who flocked to the scene would be able to recall its grotesque details with vivid accuracy for years to come. After waking to the ominous sound of crackling in the near distance, trudging masses of townsfolk found themselves nudged from their beds and sucked unwittingly towards the unfamiliar source of pulsing orange heat and light at which a crowd had begun to slowly form in a trance-like stupor. A house had been set ablaze, its glowing embers curling into the night air and spirals of toxic smoke spewing into the crowd. As those present watched the fiery collapse of the building into smoldering mounds of rubble, they realized, to their horror, that more nightmarish images than they could have imagined lay flickering before them in the hazy gloom. Within a few yards of the burning ruins a dog’s decapitated head, cut cleanly to the neck, sat unblinking on the grass next to the mangled headless corpse of its former body, legs sprawled wildly in a sticky pool of blood. Near the dog rested the grisly charred skull and what remained of the skeletal shoulders and upper ribcage of a man, no longer resembling anything describable as human. Most tragic of all, a few yards further on the yard lay a pathetic splatter of ashen bones, fleshy organs, and dismembered extremities, loosely clustered around what could vaguely be discerned as the lifeless bodies of two small children who had been burned alive.Scholarships & Prizes Office.

Maternal obesity during pregnancy alters daily activity and feeding cycles, and hypothalamic clock gene expression in adult male mouse offspring

An obesogenic diet adversely affects the endogenous mammalian circadian clock, altering daily activity and metabolism, and resulting in obesity. We investigated whether an obese pregnancy can alter the molecular clock in the offspring hypothalamus, resulting in changes to their activity and feeding rhythms. Female mice were fed a control (C, 7% kcal fat) or high fat diet (HF, 45% kcal fat) before mating and throughout pregnancy. Male offspring were fed the C or HF diet postweaning, resulting in four offspring groups: C/C, C/HF, HF/C, and HF/HF. Daily activity and food intake were monitored, and at 15 weeks of age were killed at six time-points over 24 h. The clock genes Clock, Bmal1, Per2, and Cry2 in the suprachiasmatic nucleus (SCN) and appetite genes Npy and Pomc in the arcuate nucleus (ARC) were measured. Daily activity and feeding cycles in the HF/C, C/HF, and HF/HF offspring were altered, with increased feeding bouts and activity during the day and increased food intake but reduced activity at night. Gene expression patterns and levels of Clock, Bmal1, Per2, and Cry2 in the SCN and Npy and Pomc in the ARC were altered in HF diet-exposed offspring. The altered expression of hypothalamic molecular clock components and appetite genes, together with changes in activity and feeding rhythms, could be contributing to offspring obesity

Large-scale (CO)-C-13 J=5 -\u3e 4 and [C I] mapping Of Orion A

We present maps of the 13CO J = 5 → 4 (551 GHz) and [C I] 3P1 → 3P0 (492 GHz) emission in the Orion A molecular cloud, covering a 05 × 2° area. A large velocity gradient (LVG) analysis of 13CO J = 5 → 4 and J = 1 → 0 suggests that the gas temperatures in the northern part of OMC-1 (north of Δδ = -20\u27) are ~45 K and are, on average, at least 20 K higher than those to the south. The average 13CO column density is log(N/cm-2) = 16.4 ± 0.3 and is fairly constant throughout the cloud, even in the low-temperature region south of BN/KL. LVG modeling of the [C I] emission shows a typical C0 column density of 2 × 1017 cm-2, which yields a C/CO abundance ratio in the cloud of ~0.1 (rising to levels in excess of 0.5 at the cloud edges). Comparison of the Δ-variance (which measures spatial structure in a manner similar to a power spectrum) of the Submillimeter Wave Astronomy Satellite [C I], Five College Radio Astronomy Observatory 13CO J = 1 → 0, and CS J = 1 → 0 velocity-integrated maps suggests that the [C I] and 13CO emission arise from the same gas. In contrast, the CS emission likely originates in gas that is considerably more clumpy

Herschel/HIFI discovery of interstellar chloronium (H2Cl+)

We report the first detection of chloronium, H2Cl+, in the interstellar medium, using the HIFI instrument aboard the Herschel Space Observatory. The 212−101 lines of ortho-H35 2 Cl+ and ortho-H37 2 Cl+ are detected in absorption towards NGC 6334I, and the 111−000 transition of para-H35 2 Cl+ is detected in absorption towards NGC 6334I and Sgr B2(S). The H2Cl+ column densities are compared to those of the chemically-related species HCl. The derived HCl/H2Cl+ column density ratios, ∼1–10, are within the range predicted by models of diffuse and dense photon dominated regions (PDRs). However, the observed H2Cl+ column densities, in excess of 1013 cm−2, are significantly higher than the model predictions. Our observations demonstrate the outstanding spectroscopic capabilities of HIFI for detecting new interstellar molecules and providing key constraints for astrochemical models
