Nutrient pollution enhances productivity and framework dissolution in algae- but not in coral-dominated reef communities.

Mar Pollut Bull 2021 May 10;168:112444. Epub 2021 May 10.

Marine Ecology, Faculty of Biology and Chemistry, University of Bremen, Bremen, Germany.

Ecosystem services provided by coral reefs may be susceptible to the combined effects of benthic species shifts and anthropogenic nutrient pollution, but related field studies are scarce. We thus investigated in situ how dissolved inorganic nutrient enrichment, maintained for two months, affected community-wide biogeochemical functions of intact coral- and degraded algae-dominated reef patches in the central Red Sea. Results from benthic chamber incubations revealed 87% increased gross productivity and a shift from net calcification to dissolution in algae-dominated communities after nutrient enrichment, but the same processes were unaffected by nutrients in neighboring coral communities.

Cancer progression as a sequence of atavistic reversions.

Bioessays 2021 May 13:e2000305. Epub 2021 May 13.

Beyond Center for Fundamental Concepts in Science, Arizona State University, Tempe, Arizona, USA.

It has long been recognized that cancer onset and progression represent a type of reversion to an ancestral quasi-unicellular phenotype. This general concept has been refined into the atavistic model of cancer that attempts to provide a quantitative analysis and testable predictions based on genomic data. Over the past decade, support for the multicellular-to-unicellular reversion predicted by the atavism model has come from phylostratigraphy. Read More

Nonlinear Circular Dichroism in Mie-Resonant Nanoparticle Dimers.

Nano Lett 2021 May 13. Epub 2021 May 13.

Nonlinear Physics Centre, Research School of Physics, Australian National University, Canberra, Australian Capital Territory 2601, Australia.

We studied the nonlinear response of a dimer composed of two identical Mie-resonant dielectric nanoparticles illuminated normally by a circularly polarized light. We developed a general theory describing hybridization of multipolar modes of the coupled nanoparticles and reveal nonvanishing nonlinear circular dichroism (CD) in the second-harmonic generation (SHG) signal enhanced by the multipolar resonances in the dimer, provided its axis is oriented under an angle to the crystalline lattice of the dielectric material. We supported our multipolar hybridization theory by experimental results obtained for the AlGaAs dimers placed on an engineered substrate. Read More

Harvesting water from unsaturated atmospheres: deliquescence of salt secreted onto leaf surfaces drives reverse sap flow in a dominant arid climate mangrove, Avicennia marina.

New Phytol 2021 May 13. Epub 2021 May 13.

Plant Science Division, Research School of Biology, The Australian National University, Acton, ACT, 2601, Australia.

The mangrove Avicennia marina adjusts internal salt concentrations by foliar salt secretion. Deliquescence of accumulated salt causes leaf wetting which may provide a water source for salt-secreting plants in arid coastal wetlands where high nocturnal humidity can usually support deliquescence whereas rainfall events are rare. We tested the hypotheses that salt deliquescence on leaf surfaces can drive top-down rehydration, and that such absorption of moisture from unsaturated atmospheres makes a functional contribution to dry season shoot water balances.

Studying nursing at Australian satellite university campuses: A review of teaching, learning and support.

Aust J Rural Health 2021 Apr;29(2):226-235

College of Medicine and Dentistry, James Cook University, Douglas, QLD, Australia.

Distribution of the Australian health workforce is uneven, with the majority of health professionals favouring metropolitan areas over rural and remote regions. Although nurses account for the largest proportion of the Australian rural and remote health workforce, difficulties with staff recruitment and retention can impact the health care outcomes of these vulnerable populations. Satellite university campuses that offer undergraduate nursing programs might therefore contribute to a more sustainable rural and remote nursing workforce. Read More

rTMS for depression: The difficult transition from research to clinical practice.

Aust N Z J Psychiatry 2021 May 13:48674211011242. Epub 2021 May 13.

U1172 - LilNCog - Lille Neuroscience & Cognition, Université de Lille, Inserm, CHU Lille, Lille, France.

The publication of the 2020 Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the management of mood disorders was followed by a series of correspondences discussing the place of repetitive transcranial magnetic stimulation (rTMS) in the sequence care for the routine treatment of depression. The controversy has led to an intense debate about the positioning of this neuromodulation technique in the clinical armamentarium for depression in the Australian and New Zealand Journal of Psychiatry. The many arguments presented by the authors to defend their respective points of view can be summarised in two main key issues: (i) the interpretation of the level of evidence of rTMS for depression and (ii) the characterisation of patients who could benefit from this treatment.

Glob Chang Biol 2021 May 12. Epub 2021 May 12.

Forestry Research Institute of Ghana, Council for Scientific and Industrial Research, University, P.O. Box 63, Kumasi, Ghana.

Fine roots constitute a significant component of the net primary productivity (NPP) of forest ecosystems but are much less studied than above-ground NPP. Comparisons across sites and regions are also hampered by inconsistent methodologies, especially in tropical areas. Here, we present a novel dataset of fine root biomass, productivity, residence time, and allocation in tropical old-growth rainforest sites worldwide, measured using consistent methods, and examine how these variables are related to consistently determined soil and climatic characteristics.

Breaching the Delivery Barrier: Chemical and Physical Airway Epithelium Disruption Strategies for Enhancing Lentiviral-Mediated Gene Therapy.

Front Pharmacol 2021 26;12:669635. Epub 2021 Apr 26.

Adelaide Medical School, University of Adelaide, Adelaide, SA, Australia.

The lungs have evolved complex physical, biological and immunological defences to prevent foreign material from entering the airway epithelial cells. These mechanisms can also affect both viral and non-viral gene transfer agents, and significantly diminish the effectiveness of airway gene-addition therapies. One strategy to overcome the physical barrier properties of the airway is to transiently disturb the integrity of the epithelium prior to delivery of the gene transfer vector. Read More
