Helle Harnisch, Anett Pfeiffer
Based on 10 months of fieldwork in the Acholi region of northern Uganda among youth and adults who were forcefully recruited into the Lord's Resistance Army (LRA) during the war, this article provides qualitative details to research on 'appetitive aggression.' Through two case-stories the article unfolds first person articulations of how 'appetitive aggression' is experienced as 'the urge to kill' and how it relates to the emic Acholi spiritual concept of 'cen'; a local Luo expression used to describe places and human beings possessed by evil spirits...

Some mosses stay green and survive long even under desiccation. Dissipation mechanisms of excess excitation energy were studied in two drought-tolerant moss species adapted to contrasting niches: shade-adapted Rhytidiadelphus squarrosus and sun-adapted Rhytidium rugosum in the same family. (1) Under wet conditions, a light-induced nonphotochemical quenching (NPQ) mechanism decreased the yield of photosystem II (PSII) fluorescence in both species. The NPQ extent saturated at a lower illumination intensity in R...

Traumatizing events are known to have consequences for the victim which may lead to the development of several well-known mental disorders. Recent research has shown that traumatic events may affect not only the victims' lives, but also that of their progeny. It is generally accepted that this transmission of trauma occurs through parental behavior; however as has been recently discovered, the effects of trauma may also be inherited due to induced alterations in gene expression. These changes, so called epigenetic modifications, illuminate the interaction between genes and the environment...

Daniel Pleissner, Birgit A Rumpold
Various organic residues occur globally in the form of straw, wood, green biomass, food waste, feces, manure etc. Other utilization strategies apart from anaerobic digestion, composting and incineration are needed to make use of the whole potential of organic residues as sources of various value added compounds. This review compares the cultivation of heterotrophic microalgae and insects using organic residues as nutrient sources and illuminates their potential with regard to biomass production, productivity and yield, and utilization strategies of produced biomasses...

A novel Phototrophic - Enhanced Biological Phosphorus Removal (Photo-EBPR) system, consisting of a consortium of photosynthetic organisms and polyphosphate accumulating organisms (PAOs), was studied in this work. A sequencing batch reactor was fed with a mixture of acetate and propionate (75%-25%) and subjected to dark/light cycles in order to select a photo-EBPR system containing PAOs and photosynthetic organisms, the latter likely providers of oxygen to the system. The results from the selection period (stage 1) showed that the photo-EBPR culture was capable of performing P release in the dark and P uptake in the presence of light, under limited oxygen concentrations...

By decorating nickel copper hydroxide (NCH) with Ag nanowires (Ag NWs), a 1.7 fold enhancement in areal capacitance (5.4 F cm(-2)) and a 1.8 fold increment in gravimetric capacitance (3182 F g(-1)) under light illumination were achieved. The improved supercapacitor performances of the composites under visible-light illumination were demonstrated and a reasonable explanation for this newly-discovered phenomenon was proposed. The plasmonic effect of Ag NWs was demonstrated by hot-electron generation. The decorated Ag NWs served as a stimulus for redox reactions...

The engineering of living plants for visible light emission and sustainable illumination is compelling because plants possess independent energy generation and storage mechanisms and autonomous self-repair. Herein, we demonstrate a plant nanobionic approach that enables exceptional luminosity and lifetime utilizing four chemically-interacting nanoparticles, including firefly luciferase conjugated silica (SNP-Luc), D-luciferin releasing poly(lactic-co-glycolic acid) (PLGA-LH2), coenzyme A functionalized chitosan (CS-CoA) and semiconductor nanocrystal phosphors for longer wavelength modulation...

Emulsion droplets can serve as ideal compartments for reactions. In fact, in many cases, the chemical reactions are supposed to be triggered at a desired position and time without change of the system environment. Here, we present a type of light and magnetic dual-responsive Pickering emulsion micro-reactor by co-adsorption of light-sensitive titania (TiO2) and super paramagnetic iron oxide (Fe3O4) nanoparticles at the oil-water interface of emulsion droplets. The droplets encapsulating different reactants in advance can be driven close to each other by an external magnetic field, and then chemical reaction is triggered by UV illumination due to the contact of the isolated reactants as a result of droplet coalescence...

Herein, for the first time we applied metal-metal bond energy factor for the evolution of porous Se-Te alloy. Porous Se-Te material has been prepared from their elemental states only through heating-cooling process in silicone oil without using any reagent, surfactant or capping agent. Surprisingly the reaction occurred at much lower temperature (240 °C) than the m.p. (450 °C) of Te0. The nucleation and growth have been clarified by means of varied bond energy for the first time. Difference in bond energy between hetero metal-metal bond (Se-Te) and homo metal-metal (Se-Se) directs nucleation and growth towards the fabrication of porous structure even from their elemental state where low angle grain boundary (LAGB) and high angle grain boundary (HAGB) movements play their governing roles...

Racial prejudice is associated with a fundamental distinction between "us" and "them"-a distinction linked to the perceived overlap between representations of the self and others. Implicit prejudice has been shown to reduce the intensity of White individuals' hand ownership sensation as induced by the Rubber Hand Illusion (RHI) with dark rubber hands. However, evidence for this link to implicit prejudice comes from self-report questionnaire data regarding the RHI. As an alternative, we assessed the onset time of the RHI...

A monolithic tandem solar cell consisting of crystalline Si (c-Si)/indium tin oxide (ITO)/CuGaSe2 (CGSe) was demonstrated by stacking a CGSe solar cell on a c-Si/ITO solar cell to obtain a photovoltaic conversion efficiency of about 10%. Electrical analyses based on cell-selective light absorption were applied to individually characterize the photovoltaic performances of the top and bottom subcells. Illumination at a frequency that could be absorbed only by a targeted top or bottom subcell permitted measurement of the open-circuit voltage of the target subcell and the shunt resistance of the non-target subcell...

Male pattern baldness (MPB) or androgenetic alopecia is one of the most common conditions affecting men, reaching a prevalence of ~50% by the age of 50; however, the known genes explain little of the heritability. Here, we present the results of a genome-wide association study including more than 70,000 men, identifying 71 independently replicated loci, of which 30 are novel. These loci explain 38% of the risk, suggesting that MPB is less genetically complex than other complex traits. We show that many of these loci contain genes that are relevant to the pathology and highlight pathways and functions underlying baldness...

Photoreceptor-mediated light signaling plays a critical role in plant growth, development, and stress responses but its contribution to the spatial regulation of photoinhibition and photoprotection within the canopy remains unclear. Here, we show that low red/far-red (L-R/FR) ratio light conditions significantly alleviate PSII and PSI photoinhibition in the shade leaves of tomato plants. This protection is accompanied by a phytochrome A (phyA)-dependent induction of LONG HYPOCOTYL 5 (HY5). HY5 binds to the promoter of ABA INSENSITIVE 5 (ABI5), triggering RESPIRATORY BURST OXIDASE HOMOLOG1 (RBOH1)-dependent H2O2 production in the apoplast...

The advent of cancer immunotherapy (CIT) and its success in treating primary and metastatic cancer may offer substantially improved outcomes for patients. Despite recent advancements, many malignancies remain resistant to CIT, among which are brain metastases, a particularly virulent disease with no apparent cure. The immunologically unique niche of the brain has prompted compelling new questions in immuno-oncology such as the effects of tissue-specific differences in immune response, heterogeneity between primary tumors and distant metastases, and the role of spatiotemporal dynamics in shaping an effective anti-tumor immune response...

Aiming at alleviating the adverse effect of poor light penetrability on microalgae growth, planar waveguide modules functioned as diluting and redistributing the intense incident light within microalgae culture more homogeneously were introduced into a lab-scale open raceway pond (ORP) for Nannochloropsis oculata cultivation. As compared to the conventional ORP, the illumination surface area to volume ratio and effective illuminated volume percentage in the proposed ORP were respectively improved by 5.53 times and 19...

We demonstrate dynamic trapping and manipulation of nanoparticles with plasmonic holograms. By tailoring the illumination pattern of an incident light beam with a computer-controlled spatial light modulator, constructive and destructive interference of plasmon waves create a focused hotspot that can be moved across a surface. Specifically, a computer-generated hologram illuminating the perimeter of a silver Bull's Eye nanostructure generates surface plasmons that propagate towards the center. Shifting the phase of the plasmon waves as a function of space gives complete control over the location of the focus...

The absence of near-infrared (NIR) solar cells with high open circuit voltage (Voc) and external quantum efficiency (EQE) has impeded progress toward achieving organic photovoltaic (OPV) power conversion efficiency PCE > 15%. Here we report a small energy gap (1.3 eV), chlorinated nonfullerene acceptor-based solar cell with PCE = 11.2 ± 0.4%, short circuit current of 22.5 ± 0.6 mA cm(-2), Voc = 0.70 ± 0.01 V and fill factor of 0.71 ± 0.02, which is the highest performance reported to date for NIR single junction OPVs...

Unraveling the role of surface oxide on affecting its native metal disulfide' CO2 photoreduction remains a grand challenge. Herein, we initially construct metal disulfide atomic layers and hence deliberately create oxidized domains on their surfaces. As an example, SnS2 atomic layers with different oxidation degrees are successfully synthesized. In situ FTIR spectra disclose the COOH* radical is the main intermediate, while density-functional-theory calculations reveal the COOH* formation is the rate-limiting step...

The need to develop a red-light-emitting pyrotechnic illuminant has garnered interest from the pyrotechnics community due to potential Environmental Protection Agency (EPA) regulations of strontium and chlorinated organic materials. To address these environmental regulatory concerns, the development of lithium-based red-light-emitting pyrotechnic compositions of high purity and color is described. These formulations do not contain strontium or chlorinated organic materials. Rather, the disclosed formulations are based on a non-hygroscopic dilithium high-nitrogen salt which serves as both the oxidizer and red colorant...

Recently, autonomous vehicles, particularly self-driving cars, have received significant attention owing to rapid advancements in sensor and computation technologies. In addition to traffic sign recognition, road lane detection is one of the most important factors used in lane departure warning systems and autonomous vehicles for maintaining the safety of semi-autonomous and fully autonomous systems. Unlike traffic signs, road lanes are easily damaged by both internal and external factors such as road quality, occlusion (traffic on the road), weather conditions, and illumination (shadows from objects such as cars, trees, and buildings)...
