Methane emissions from natural gas infrastructure and use in the urban region of Boston, Massachusetts [Sustainability Science]

17-Feb-2015 | Kathryn McKain; Adrian Down; Steve M. Raciti; John Budney; Lucy R. Hutyra; Cody Floerchinger; Scott C. Herndon; Thom ..., Proceedings of the National Academy of Sciences current issue, 2015

Methane emissions from natural gas delivery and end use must be quantified to evaluate the environmental impacts of natural gas and to develop and assess the efficacy of emission reduction strategies. We report natural gas emission rates for 1 y in the urban region of Boston, using a ...

Proton-coupled electron transfer and the role of water molecules in proton pumping by cytochrome c oxidase [Biophysics and Computational Biology]

17-Feb-2015 | Vivek Sharma; Giray Enkavi; Ilpo Vattulainen; Tomasz Róg; Mårten Wikström, Proceedings of the National Academy of Sciences current issue, 2015

Molecular oxygen acts as the terminal electron sink in the respiratory chains of aerobic organisms. Cytochrome c oxidase in the inner membrane of mitochondria and the plasma membrane of bacteria catalyzes the reduction of oxygen to water, and couples the free energy of the reaction to proton ...

Plasma butyrylcholinesterase regulates ghrelin to control aggression [Neuroscience]

17-Feb-2015 | Vicky Ping Chen; Yang Gao; Liyi Geng; Robin J. Parks; Yuan-Ping Pang; Stephen Brimijoin, Proceedings of the National Academy of Sciences current issue, 2015

Ongoing mouse studies of a proposed therapy for cocaine abuse based on viral gene transfer of butyrylcholinesterase (BChE) mutated for accelerated cocaine hydrolysis have yielded surprising effects on aggression. Further investigation has linked these effects to a reduction in circulating ...

Reply to O'Neill et al. and O'Sullivan: Fertility reduction will help, but only in the long term [Biological Sciences]

10-Feb-2015 | Corey J. A. Bradshaw; Barry W. Brook, Proceedings of the National Academy of Sciences current issue, 2015

O’Neill et al. (1) and O’Sullivan (2) argue that the results of our global population scenarios (3) are not credible. Here we demonstrate that their arguments are peripheral and that our conclusions are robust. Both O’Neill et al. (1) and O’Sullivan (2) overlook that the demographic rates we used ...

Reversible catalytic dehydrogenation of alcohols for energy storage [Chemistry]

10-Feb-2015 | Peter J. Bonitatibus Jr.; Sumit Chakraborty; Mark D. Doherty; Oltea Siclovan; William D. Jones; Grigorii L. Soloveichik, Proceedings of the National Academy of Sciences current issue, 2015

Reversibility of a dehydrogenation/hydrogenation catalytic reaction has been an elusive target for homogeneous catalysis. In this report, reversible acceptorless dehydrogenation of secondary alcohols and diols on iron pincer complexes and reversible oxidative dehydrogenation of primary ...

Population stabilization potential and its benefits underestimated [Biological Sciences]

10-Feb-2015 | Jane N. O’Sullivan, Proceedings of the National Academy of Sciences current issue, 2015

Bradshaw and Brook’s report “Human population reduction is not a quick fix for environmental problems” (1) argues that plausible efforts to reduce birth rates will make little difference to the course of human population this century. Although they emphasize that population reduction is highly ...

Endostatin: A novel inhibitor of androgen receptor function in prostate cancer [Biochemistry]

03-Feb-2015 | Joo Hyoung Lee; Tatyana Isayeva; Matthew R. Larson; Anandi Sawant; Ha-Ram Cha; Diptiman Chanda; Igor N. Chesnokov; S ..., Proceedings of the National Academy of Sciences current issue, 2015

Acquired resistance to androgen receptor (AR)-targeted therapies compels the development of novel treatment strategies for castration-resistant prostate cancer (CRPC). Here, we report a profound effect of endostatin on prostate cancer cells by efficient intracellular trafficking, direct ...

Predictive isotope model connects microbes in culture and nature [Earth, Atmospheric, and Planetary Sciences]

23-Dec-2014 | Shuhei Ono; Min Sub Sim; Tanja Bosak, Proceedings of the National Academy of Sciences current issue, 2014

In PNAS, Wing and Halevy (1) present a new model that quantitatively describes the magnitude of sulfur isotope fractionation produced by dissimilatory microbial sulfate reduction (MSR). MSR is a major player in the global biogeochemical cycles and is responsible for the respiration of up to 30% ...

Shortwave and longwave radiative contributions to global warming under increasing CO2 [Earth, Atmospheric, and Planetary Sciences]

25-Nov-2014 | Aaron Donohoe; Kyle C. Armour; Angeline G. Pendergrass; David S. Battisti, Proceedings of the National Academy of Sciences current issue, 2014

In response to increasing concentrations of atmospheric CO2, high-end general circulation models (GCMs) simulate an accumulation of energy at the top of the atmosphere not through a reduction in outgoing longwave radiation (OLR)—as one might expect from greenhouse gas forcing—but through an ...

Human population reduction is not a quick fix for environmental problems [Population Biology]

18-Nov-2014 | Corey J. A. Bradshaw; Barry W. Brook, Proceedings of the National Academy of Sciences current issue, 2014

The inexorable demographic momentum of the global human population is rapidly eroding Earth’s life-support system. There are consequently more frequent calls to address environmental problems by advocating further reductions in human fertility. To examine how quickly this could lead to a smaller ...
