Homo floresiensis, a primitive hominin species discovered in Late Pleistocene sediments at Liang Bua (Flores, Indonesia)1, 2, 3, has generated wide interest and scientific debate. A major reason this taxon is controversial is because the H. floresiensis-bearing deposits, which include associated stone artefacts2, 3, 4 and remains of other extinct endemic fauna5, 6, were dated to between about 95 and 12 thousand calendar years (kyr) ago2, 3, 7. These ages suggested that H. floresiensis survived until long after modern humans reached Australia by ~50 kyr ago8, 9, 10. Here we report new stratigraphic and chronological evidence from Liang Bua that …

Approximately one in every five Australians will experience a mental illness each year (ABS, 2007). Mental illnesses are not homogenous. There are no clearly established clinical pathways and, as such, care and treatment is necessarily highly individualised.
Thermally Controlling The Singlet-Triplet Energy Gap Of A Diradical In The Solid State, Yuanting Su, Xingyong Wang, Lei Wang, Zaichao Zhang, Xinping Wang, You Song, Philip P. Power

Diradicals, molecules with two unpaired electrons, are reactive intermediates that play an important role in many fields. Their defining feature is the energy difference between their singlet and triplet states, which provides direct information on the extent of their electron exchange interactions. Such knowledge is essential for understanding their diradical character, which is controllable internally by modification of the electronic and steric properties of the substituents. We now report that the energy gap of a diradical in the solid state can also be controlled by an external stimulus. The dication diradical of 4,4′′-di(bisphenylamino)-p-terphenyl exhibits two singlet states with different exchange …

There is now good evidence in several taxa that animal coloration positively reflects an individual's antioxidant capacity. However, even though telomeres, a marker of ageing, are known to be vulnerable to reactive oxygen species (ROS) attacks, no studies have ever assessed whether colour fading reflects the rate of biological ageing in any taxa. Here, we measured colour fading, telomere erosion (a measure of biological ageing) and ROS levels in painted dragons. We show that individuals that were better at maintaining their coloration during the three months of the study suffered a higher cost in terms of telomere erosion, but overall …

The 1-deoxysphingolipids (1-deoxySLs) are formed by an alternate substrate usage of the enzyme, serine-palmitoyltransferase, and are devoid of the C1-OH-group present in canonical sphingolipids. Pathologically elevated 1-deoxySL levels are associated with the rare inherited neuropathy, HSAN1, and diabetes type 2 and might contribute to β cell failure and the diabetic sensory neuropathy. In analogy to canonical sphingolipids, it was assumed that 1-deoxySLs also bear a (4E) double bond, which is normally introduced by sphingolipid delta(4)-desaturase 1. This, however, was never confirmed. We therefore supplemented HEK293 cells with isotope-labeled D3-1-deoxysphinganine and compared the downstream formed D3-1-deoxysphingosine (1-deoxySO) to a commercial synthetic …
Chronic Administration Of Aripiprazole Activates Gsk3Β-Dependent Signalling Pathways, And Up-Regulates GabaA Receptor Expression And Creb1 Activity In Rats, Bo Pan, Xu-Feng Huang, Chao Deng

Aripiprazole is a D2-like receptor (D2R) partial agonist with a favourable clinical profile. Previous investigations indicated that acute and short-term administration of aripiprazole had effects on PKA activity, GSK3β-dependent pathways, GABAA receptors, NMDA receptor and CREB1 in the brain. Since antipsychotics are used chronically in clinics, the present study investigated the long-term effects of chronic oral aripiprazole treatment on these cellular signalling pathways, in comparison with haloperidol (a D2R antagonist) and bifeprunox (a potent D2R partial agonist). We found that the Akt-GSK3β pathway was activated by aripiprazole and bifeprunox in the prefrontal cortex; NMDA NR2A levels were reduced by aripiprazole …

In the early days of the Industrial Revolution, no one would have thought that their burning of fossil fuels would have an almost immediate effect on the climate. But our new study, published today in Nature, reveals that warming in some regions actually began as early as the 1830s. That is much earlier than previously thought, so our discovery redefines our understanding of when human activity began to influence our climate.
Re-Identification Of An Exotic Bee Introduced To The Hunter Valley Region, New South Wales -Seladonia Hotoni (Vachal, 1903) (Hymenoptera: Halictidae), Michael Batley, Alain Pauly, John R. Gollan, Michael B. Ashcroft, Gontran Sonet

In 2004 and 2006, well-established populations of an exotic halictine bee were found in the Upper Hunter Valley region of New South Wales, Australia. On the basis of morphology, the species was identified as Halictus (Seladonia) smaragdulus Vachal, 1895 by an expert familiar with that genus. Subsequently, it was discovered that there are six species in the S. smaragdula complex, but none of the six had the same mitochondrial DNA barcode as the species found in Australia. The introduced bee has been shown to be conspecific with an African species by mitochondrial COI DNA sequences and identified as Seladonia hotoni …

Owing to the increased proton affinity that results from additional negative charges, multiply-charged anions have been proposed as one route to prepare and access a range of new and powerful "superbases". Paradoxically, while the additional electrons in polyanions increase basicity they serve to diminish the electron binding energy and thus, it had been thought, hinder experimental synthesis. We report the synthesis and isolation of the ortho-diethynylbenzene dianion (ortho-DEB2−) and present observations of this novel species undergoing gas-phase proton-abstraction reactions. Using a theoretical model based on Marcus-Hush theory, we attribute the stability of ortho-DEB2− to the presence of a barrier that …

Human migration to Australia occurred over 62,000 years ago. Those first Australians established one of the oldest continuous populations on the driest of the inhabited continents, surviving the world's longest drought (>10,000 y). Indeed, the traditional owners established a cultural identity and sustainable lifestyle thousands of years before any of the more recognised ancient civilisations. However, our temperature and rainfall variations belie the national stereotype, with temperatures from -23oC (Charlotte Pass, New South Wales) to 50.7oC (Oodnadatta, South Australia), and annual rainfalls from 125 mm (Lake Eyre, South Australia) through to 12,461 mm in the tropical north-east (Bellenden Ker, …

Background Difficulties in kneeling, one of the poorest scoring functional outcomes post total knee arthroplasty (TKA),have been attributed to a lack of patient education. This is the first study to investigate specific factors affecting a patient's perceived ability to kneel post TKA, following exposure to a preoperative kneeling education session. Materials and methods A cross-sectional study was conducted following TKA with patients who had been educated about kneeling prior to the operation. Patients completed kneeling questionnaires at 6 (n = 115) and 12 (n = 82) months post TKA. In addition to the 12-month kneeling questionnaire, patients also completed the …
Situation Awareness: When Nurses Decide To Admit Or Not Admit A Person With Mental Illness As An Involuntary Patient, Christopher F. Patterson, Nicholas Procter, Luisa Toffoli
Situation Awareness: When Nurses Decide To Admit Or Not Admit A Person With Mental Illness As An Involuntary Patient, Christopher F. Patterson, Nicholas Procter, Luisa Toffoli
Faculty of Science, Medicine and Health - Papers: part A
Aim This paper will explore the application of situation awareness in nursing to determine its suitability as a framework to study how the decision to admit or not admit a person as an involuntary patient is made. Background The decision by a specially qualified nurse to admit or not admit a person to a mental health facility against their will remains a central component of contemporary mental health legislation. The decision has an impact on a person's autonomy and human rights. Conversely, the decision to admit may facilitate urgent assessment and treatment and ensure the safety of the individual and …
Comparative Mt Genomics Of The Tipuloidea (Diptera: Nematocera: Tipulomorpha) And Its Implications For The Phylogeny Of The Tipulomorpha, Xiao Zhang, Zehui Kang, Meng Mao, Xuankun Li, Stephen L. Cameron, Herman De Jong, Mengqing Wang, Ding Yang

A traditionally controversial taxon, the Tipulomorpha has been frequently discussed with respect to both its familial composition and relationships with other Nematocera. The interpretation of internal relationships within the Tipuloidea, which include the Tipulidae sensu stricto, Cylindrotomidae, Pediciidae and Limoniidae, is also problematic. We sequenced the first complete mitochondrial (mt) genome of Symplecta hybrida (Meigen, 1804), which belongs to the subfamily Chioneinae of family Limoniidae, and another five nearly complete mt genomes from the Tipuloidea. We did a comparative analysis of these mt genomics and used them, along with some other representatives of the Nematocera to construct phylogenetic trees. Trees …

In optically stimulated luminescence (OSL) dating, the single aliquot regenerative-dose (SAR) method has been used extensively for determining equivalent doses (De) in quartz. A variation of the SAR method is the “standardised growth curve” (SGC) method, which has been used as an efficient procedure to save measurement time during dating studies. During the application of the SGC method one establishes the SGC and calculation of the De of an aliquot requires only measurement of the standardised natural dose signal. Recently, a “global standardised growth curve” (gSGC) method was developed as an improved version of the SGC procedure. During the application …

Biological activity is a major factor in Earth's chemical cycles, including facilitating CO2 sequestration and providing climate feedbacks. Thus a key question in Earth's evolution is when did life arise and impact hydrosphere-atmosphere-lithosphere chemical cycles? Until now, evidence for the oldest life on Earth focused on debated stable isotopic signatures of 3,800-3,700 million year (Myr)-old metamorphosed sedimentary rocks and minerals1,2 from the Isua supracrustal belt (ISB), southwest Greenland3. Here we report evidence for ancient life from a newly exposed outcrop of 3,700-Myr-old metacarbonate rocks in the ISB that contain 1-4-cm-high stromatolites-macroscopically layered structures produced by microbial communities. The ISB stromatolites …

The South East Asian Melanesian (SEAM) region contains the world's largest deposits of nickel lateritic ores. Environmental impacts may occur if mining operations are not adequately managed. Effects data for tropical ecosystems are required to assess risks of contaminant exposure and to derive water quality guidelines (WQG) to manage these risks. Currently, risk assessment tools and WQGs for the tropics are limited due to the sparse research on how contaminants impact tropical biota. As part of a larger project to develop appropriate risk assessment tools to ensure sustainable nickel production in SEAM, nickel effects data were required. The aim of …

The distribution of methane (CH4/ in the stratosphere can be a major driver of spatial variability in the dryair column-averaged CH4 mixing ratio (XCH4), which is being measured increasingly for the assessment of CH4 surface emissions. Chemistry-transport models (CTMs) therefore need to simulate the tropospheric and stratospheric fractional columns of XCH4 accurately for estimating surface emissions from XCH4. Simulations from three CTMs are tested against XCH4 observations from the Total Carbon Column Network (TCCON). We analyze how the model– TCCON agreement in XCH4 depends on the model representation of stratospheric CH4 distributions. Model equivalents of TCCON XCH4 are computed with …

Introduction: Attempting to curb the rising epidemic of hypertension, South Africa implemented legislation in June 2016 mandating maximum sodium levels in a range of manufactured foods that contribute significantly to population salt intake. This natural experiment, comparing two African countries with and without salt legislation, will provide timely information on the impact of legislative approaches addressing the food supply to improve blood pressure in African populations. This article outlines the design of this ongoing prospective nested cohort study. Methods and analysis: Baseline sodium intake was assessed in a nested cohort of the WHO Study on global AGEing and adult health …

Background: Modern diets, characterised by excess consumption of processed foods, are accompanied by an epidemic of chronic diseases. Cardiovascular disease and depression carry a large burden of disease and often occur together. Poor dietary patterns have been identified as an independent risk factor for depression while healthy diets with minimally processed food are protective. Traditional Mediterranean diets have been shown to reduce risk of cardiovascular disease; however there is a need for clinical trials in people with depression. This paper reports the study protocol of a Mediterranean-style diet intervention conducted in adults with self-reported depression. Methods/design: HELFIMED is a parallel …

The breakup of Pangea in the Jurassic saw the opening of major ocean basins at the expense of older Tethyan and Pacific oceanic plates. Although the Tethyan seafloor spreading history has been lost to subduction, proxy indicators from multiple generations of Tethyan ribbon terranes, as well as the active margin geological histories of volcanism and ophiolite obduction events can be used to reconstruct these ancient oceanic plates. The plate reconstructions presented in this study reconcile observations from ocean basins and the onshore geological record to provide a regional synthesis, embedded in a global plate motion model, of the India-Eurasia convergence …

Passive margin highlands occur on most continents on Earth and play a critical role in the cycle of weathering, erosion, and atmospheric circulation. Yet, in contrast to the well-developed understanding of collisional mountain belts, such as the Alps and Himalayas, the origin of less elevated (1-2 km) passive margin highlands is still unknown. The eastern Australian highlands are a prime example of these plateaus, but compared to others they have a well-documented episodic uplift history spanning 120 million years. We use a series of mantle convection models to show that the time-dependent interaction of plate motion with mantle downwellings and …

The revegetation of cleared landscapes with woody plants (termed "environmental planting") has the potential to sequester carbon (C), provide habitat, and increase biodiversity and connectivity. These environmental values are potentially offset by an increased fire hazard posed by revegetation. There is a need to understand the influence environmental planting has on landscape fire behavior and to determine how this changes as plantings age. This study examined how environmental values, regenerative capacity, fuel metrics, and potential fire behavior change with time since planting. We assessed 57 sites across the Albury-Wodonga region (New South Wales, Australia). This included a range of environmental …

High-value marine species in waters off northern Australia are at increasing risk of poaching by foreign fishing crews, according to figures from the Australian Fisheries Management Authority. The number of foreign fishing boats caught in Australian waters increased from six in 2014-15 to 20 in 2015-16. These fishers have evidently come to poach species that fetch high prices and have been overfished elsewhere in the Asia-Pacific region. They seek "lootable resources" - species that are attractive to the black market because they are expensive, easy to catch and weakly regulated.

A thermally promoted postsynthetic rearrangement has been performed on a zinc IRMOF-9-type framework bearing dimethylthiocarbamate tag groups. The rearrangement was accomplished via conventional heating at 285 °C. Crucially, despite the high temperature, the MOF maintains its high accessible surface area and pore space following thermal treatment. The structures and physical properties of the frameworks were characterized by a combination of single-crystal X-ray diffraction, powder X-ray diffraction, differential thermal-thermogravimetric analysis, and gas sorption analysis. The rearrangement results in a slightly higher level of CO2 adsorption for the modified MOF but with equivalent heat of adsorption. This work offers new perspectives …

Background: Improved performance in a given ecological niche can occur through local adaptation, phenotypic plasticity, or a combination of these mechanisms. Evaluating the relative importance of these two mechanisms is needed to better understand the cause of intra specific polymorphism. In this study, we reared populations of Lake Whitefish (Coregonus clupeaformis) representing the 'normal' (benthic form) and the 'dwarf' (derived limnetic form) ecotypes in two different conditions (control and swim-training) to test the relative importance of adaptation and acclimation in the differentiation of traits related to swimming capacity. The dwarf whitefish is a more active swimmer than the normal ecotype, …
