  • Single-cell stochastic modelling of the action of antimicrobial peptides on bacteria 

    Teimouri,Hamid; Nguyen, Thao N.; Kolomeisky, Anatoly B.; Center for Theoretical Biological Physics (2021)
    Antimicrobial peptides (AMPs) produced by multi-cellular organisms as their immune system's defence against microbes are actively considered as natural alternatives to conventional antibiotics. Although substantial progress has been achieved in studying the AMPs, the microscopic mechanisms of their functioning remain not well understood. Here, we ...
  • Urban mining by flash Joule heating 

    Deng, Bing; Luong, Duy Xuan; Wang, Zhe; Kittrell, Carter; McHugh, Emily A.; (2021)
    Precious metal recovery from electronic waste, termed urban mining, is important for a circular economy. Present methods for urban mining, mainly smelting and leaching, suffer from lengthy purification processes and negative environmental impacts. Here, a solvent-free and sustainable process by flash Joule heating is disclosed to recover precious ...
  • Triple reassortment increases compatibility among viral ribonucleoprotein genes of contemporary avian and human influenza A viruses 

    Waters, Kaitlyn; Gao, Cheng; Ykema, Matthew; Han, Lei; Voth, Lynden; (2021)
    Compatibility among the influenza A virus (IAV) ribonucleoprotein (RNP) genes affects viral replication efficiency and can limit the emergence of novel reassortants, including those with potential pandemic risks. In this study, we determined the polymerase activities of 2,451 RNP reassortants among three seasonal and eight enzootic IAVs by using a ...

    Razafindratsima, Onja H.; Raoelinjanakolona, Nasandratra Nancia; Heriniaina, Rio R.; Nantenaina, Rindra H.; Ratolojanahary, Tianasoa H.; (2021)
    Edge effects, driven by human modification of landscapes, can have critical impacts on ecological processes such as species interactions, with cascading impacts on biodiversity as a whole. Characterizing how edges affect vital biotic interactions such as seed dispersal by frugivores is important for better understanding potential mechanisms that drive ...
  • BMP-treated human embryonic stem cells transcriptionally resemble amnion cells in the monkey embryo 

    Chhabra, Sapna; Warmflash, Aryeh (2021)
    Human embryonic stem cells (hESCs) possess an immense potential to generate clinically relevant cell types and unveil mechanisms underlying early human development. However, using hESCs for discovery or translation requires accurately identifying differentiated cell types through comparison with their in vivo counterparts. Here, we set out to determine ...
  • Structural characterization of DynU16, a START/Bet v1-like protein involved in dynemicin biosynthesis 

    Alvarado, S. K.; Miller, M. D.; Bhardwaj, M.; Thorson, J. S.; Van Lanen, S. G.; (2021)
    The 1.5 Å resolution crystal structure of DynU16, a protein identified in the dynemicin-biosynthetic gene cluster, is reported. The structure adopts a di-domain helix-grip fold with a uniquely positioned open cavity connecting the domains. The elongated dimensions of the cavity appear to be compatible with the geometry of a linear polyene, suggesting ...

  • Design of organic structure directing agents to control the synthesis of zeolites for carbon capture and storage 

    Daeyaert, Frits; W. Deem, Michael (2019)
    We have de novo designed organic structure directing agents (OSDAs) for zeolites that have been predicted to be effective materials for carbon capture and storage. The zeolites were selected for their reduced parasitic energy when used as CO2 adsorbants in a pressure–temperature swing process in coal- or natural gas-fired power plants. Synthetically ...

    We present first results on the scalar coupling of weakly interacting massive particles (WIMPs) to pions from 1 t yr of exposure with the XENON1T experiment. This interaction is generated when the WIMP couples to a virtual pion exchanged between the nucleons in a nucleus. In contrast to most nonrelativistic operators, these pion-exchange currents can ...
