    • Biosensing for Multiplexed Genome Engineering: Applications in Renewable Chemical Production 

      Rogers, Jameson Kerr (2015-05-15)
      Engineered biological systems are increasingly used to produce fuels, pharmaceuticals and industrial chemicals. While transforming cells into renewable chemical factories presents an enormous opportunity, development ...

    • Biosensor Platforms for Molecular Analyses of Circulating Cancer Biomarkers 

      Shao, Huilin (2013-10-15)
      Solid cancers often shed (sub)cellular materials into the circulation, such as circulating tumor cells and extracellular microvesicles. Mounting evidence supports that these circulating materials could serve as surrogate ...

    • Biosocial Approaches to the 2013-2016 Ebola Pandemic 

      Richardson, Eugene T.; Bailor Barrie, Mohamed; Daniel Kelly, J.; Dibba, Yusupha; Koedoyoma, Songor; Farmer, Paul E. (Harvard University Press, 2016)
      Abstract Despite more than 25 documented outbreaks of Ebola since 1976, our understanding of the disease is limited, in particular the social, political, ecological, and economic forces that promote (or limit) its spread. ...

    • Biostratigraphic and Chemostratigraphic Correlation of Neoproterozoic Sedimentary Successions: Upper Tindir Group, Northwestern Canada, as a Test Case 

      Kaufman, Alan J.; Knoll, Andrew; Awramik, Stanley M. (Geological Society of America, 1992)
      Recent advances in Proterozoic micropaleontology and sedimentary isotope geochemistry suggest that improved interbasinal correlation of Neoproterozoic (1000-540 Ma) successions is possible. Because widely varying interpretations ...

    • The biosynthesis of cyanobacterial sunscreen scytonemin in intertidal microbial mat communities 

      Balskus, Emily Patricia; Case, Rebecca J.; Walsh, Christopher T. (Wiley-Blackwell, 2011)
      We have examined the biosynthesis and accumulation of cyanobacterial sunscreening pigment scytonemin within intertidal microbial mat communities using a combination of chemical, molecular, and phylogenetic approaches. Both ...

    • The Biotic Crisis and the Future of Evolution 

      Myers, Norman; Knoll, Andrew (National Academy of Sciences, 2001)
      The biotic crisis overtaking our planet is likely to precipitate a major extinction of species. That much is well known. Not so well known but probably more significant in the long term is that the crisis will surely disrupt ...

    • Bipolar Diffusion of Current Carriers in the Presence of Deep Traps 

      Rashba, Emmanuel; Tolpygo, K. B. (1957)
      We have investigated bipolar diffusion in the presence of traps, taking into consideration the dependence of minority carrier lifetime on the population of the traps, and have established criteria for the validity of the ...

    • A Bird's Eye View of Neural Circuit Formation 

      Olveczky, Bence P; Gardner, Timothy J. (Elsevier, 2011)
      Neural circuits underlying complex learned behaviors, such as speech in humans, develop under genetic constraints and in response to environmental influences. Little is known about the rules and mechanisms through which ...

    • Birdie or Bogey? How Golf Course Construction Affects Surrounding Home Values 

      Lauer, Nicholas (2023-06-30)
      When asked to think about the how building a golf course can affect a commu- nity, many people’s first thought may jump to the environmental impacts that such construction has on the surrounding area. However, the economic ...

    • Birds have paedomorphic dinosaur skulls 

      Bhullar, Bhart-Anjan Singh; Marugán-Lobón, Jesús; Racimo, Fernando; Bever, Gabe S.; Rowe, Timothy B.; Norell, Mark A.; Abzhanov, Arkhat (Nature Publishing Group, 2012)
      The interplay of evolution and development has been at the heart of evolutionary theory for more than a century. Heterochrony—change in the timing or rate of developmental events—has been implicated in the evolution of ...

    • Birds of a Feather: Patterns, Heuristics, and Constraints of Cross-Boundary Marriage Sorting 

      Zhou, Yun (2017-05-13)
      I examine of the patterns, heuristics, and constraints of contemporary marriage sorting across various social boundaries and the resulting implications for understanding social openness and closure. Using a combination of ...

    • The Birth and Growth of the Social Insurance State: Explaining Old-Age and Medical Insurance Across Countries 

      Cutler, David; Johnson, Richard (Springer Verlag, 2004)
      We seek to explain why countries have adopted national Old-Age Insurance and Health Insurance programs. Theoretical work has posited several factors that could lead to this adoption: the strain from expanding capitalism; ...

    • Birth Matters: Examining Contextual Risk and Protective Factors for Maternal Postpartum Depression 

      Ahmed, Lameya (2023-06-01)
      The transition into motherhood can be a challenging time for many women as they traverse the vast physical, social, and emotional changes that occur during pregnancy, birth, and the postpartum period. Postpartum depression ...

    • Birth of a relativistic outflow in the unusual γ-ray transient Swift J164449.3+573451
