The behavior of the net magnetic moment ΔmAFM in the antiferromagnet is directly probed …             Generation of hyper-entanglement in polarization/energy-time and discrete-frequency/energy-time in optical fibers ▶     Shuai Dong, Lingjie Yu, Wei Zhang et al.     In this paper, a generation scheme for telecom band hyper-entanglement is proposed and demonstrated based on the vector spontaneous four wave mixing (SFWM) processes in optical …             Shubnikov - de Haas oscillations, weak antilocalization effect and large linear magnetoresistance in the putative topological superconductor LuPdBi ▶     Orest Pavlosiuk, Dariusz Kaczorowski, Piotr Wiśniewski     We present electronic transport and magnetic properties of single crystals of semimetallic half-Heusler phase LuPdBi, having theoretically predicted band inversion requisite for …             Electrochemical detection of aqueous Ag+ based on Ag+-assisted ligation reaction ▶     Peng Miao, Kun Han, Bidou Wang et al.     In this work, a novel strategy to fabricate a highly sensitive and selective biosensor for the detection of Ag is proposed. Two DNA probes are designed and modified on a gold …             Collisions of deformable cells lead to collective migration ▶     Jakob Löber, Falko Ziebert, Igor S. Aranson     Collective migration of eukaryotic cells plays a fundamental role in tissue growth, wound healing and immune response. The motion, arising spontaneously or in response to …             Flagellar Kinematics and Swimming of Algal Cells in Viscoelastic Fluids ▶     B. Qin, A. Gopinath, J. Yang et al.     The motility of microorganisms is influenced greatly by their hydrodynamic interactions with the fluidic environment they inhabit. We show by direct experimental observation of …             Detection of single ion channel activity with carbon nanotubes ▶     Weiwei Zhou, Yung Yu Wang, Tae-Sun Lim et al.     Many processes in life are based on ion currents and membrane voltages controlled by a sophisticated and diverse family of membrane proteins (ion channels), which are comparable …             Error-based Extraction of States and Energy Landscapes from Experimental Single-Molecule Time-Series ▶     J. Nicholas Taylor, Chun-Biu Li, David R. Cooper et al.     Characterization of states, the essential components of the underlying energy landscapes, is one of the most intriguing subjects in single-molecule (SM) experiments due to the …             Intergenerational continuity of cell shape dynamics in Caulobacter crescentus ▶     Charles S. Wright, Shiladitya Banerjee, Srividya Iyer-Biswas et al.     We investigate the intergenerational shape dynamics of single Caulobacter crescentus cells using a novel combination of imaging techniques and theoretical modeling. We determine …             A magnetic anti-cancer compound for magnet-guided delivery and magnetic resonance imaging ▶     Haruki Eguchi, Masanari Umemura, Reiko Kurotani et al.     Research on controlled drug delivery for cancer chemotherapy has focused mainly on ways to deliver existing anti-cancer drug compounds to specified targets, e.g., by conjugating …                 Nature Nanotechnology Focus on Spin-transfer-torque memory  Access the Focus for FREE Produced with exclusive support from  Spin Transfer Technologies         • Careers & Jobs           naturejobs.com Science jobs of the week       Postdoctoral Researcher     John Innes Centre (JIC)            Postdoc Fellow     MD Anderson Cancer Center            Senior Lecturer / Lecturer     University of Glasgow            Laboratory Technician     University of Cambridge            Research Assistant II     The Scripps Research Institute (TSRI)            Postdoctoral Researcher     University of Helsinki            Postdoctoral Research Scientist     The Babraham Institute            Bioinformatics Analyst     Yeshiva University            Postdoc and Research Fellow     University of Oslo            Research Associate     Cardiff University          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.
