Understanding how animals perceive odour mixtures is central to multiple disciplines. Here we focused on carpenter ants, …             Seismological evidence for a non-monotonic velocity gradient in the topmost outer core ▶     Vivian Tang, Li Zhao, Shu-Huei Hung     The Earth's core is mostly an Fe-Ni alloy with a fraction of light elements (~10 wt%, mainly O, S and Si). Accumulation of these light elements under the core-mantle boundary …             Effects of Fe oxide on N transformations in subtropical acid soils ▶     Xianjun Jiang, Xiaoping Xin, Shiwei Li et al.     Subtropical ecosystems are often characterized by high N cycling rates, but net nitrification rates are often low in subtropical acid soils. NO3−-N immobilization into organic N …             Multiple mechanisms sustain a plant-animal facilitation on a coastal ecotone ▶     Qiang He, Baoshan Cui     Theory suggests that species distributions are expanded by positive species interactions, but the importance of facilitation in expanding species distributions at physiological …             An efficient process for wastewater treatment to mitigate free nitrous acid generation and its inhibition on biological phosphorus removal ▶     Jianwei Zhao, Dongbo Wang, Xiaoming Li et al.     Free nitrous acid (FNA), which is the protonated form of nitrite and inevitably produced during biological nitrogen removal, has been demonstrated to strongly inhibit the …             Facile synthesis of the Ti3+ self-doped TiO2-graphene nanosheet composites with enhanced photocatalysis ▶     Bocheng Qiu, Yi Zhou, Yunfei Ma et al.     This study developed a facile approach for preparing Ti3 self-doped TiO2-graphene photocatalyst by a one-step vacuum activation technology involved a relative lower temperature, …             A Vantage from Space Can Detect Earlier Drought Onset: An Approach Using Relative Humidity ▶     Alireza Farahmand, Amir AghaKouchak, Joao Teixeira     Each year, droughts cause significant economic and agricultural losses across the world. The early warning and onset detection of drought is of particular importance for …             Families of Nuclear Receptors in Vertebrate Models: Characteristic and Comparative Toxicological Perspective ▶     Yanbin Zhao, Kun Zhang, John P. Giesy et al.     Various synthetic chemicals are ligands for nuclear receptors (NRs) and can cause adverse effects in vertebrates mediated by NRs. While several model vertebrates, such as mouse, …             Synthesis and characterization of ZnS with controlled amount of S vacancies for photocatalytic H2 production under visible light ▶     Gang Wang, Baibiao Huang, Zhujie Li et al.     Controlling amount of intrinsic S vacancies was achieved in ZnS spheres which were synthesized by a hydrothermal method using Zn and S powders in concentrated NaOH solution with …                     • Careers & Jobs           naturejobs.com Science jobs of the week       Research Fellow     University of Edinburgh            Research Assistant     University of Bristol            Research Fellow     TU Dresden, Dezernat 6, Sachgebiet Organisation            Post doctoral scholar     University of California - San Francisco            Postdoctoral Position     Ecole Normale Superieure (ENS Paris)            Postdoctoral Research Assistant     Harper Adams University            postdoctoral fellow     Johns Hopkins University Shcool of Medicine            Postdoctoral Researcher     Karolinska Institutet (KI)            PhD Student     Robert Koch-Institut            Research Technician     Queen Mary University of London          No matter what your career stage, student, postdoc or senior scientist, you will find articles on naturejobs.com to help guide you in your science career.
