    [Perspective] Molecular sieves for gas separation (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-07-08
    Description: Separation and purification are critical industrial processes for separating components of chemical mixtures, and these processes account for about half of industrial energy usage (1). Gas mixtures of compounds with very similar physical properties are particularly difficult to separate. On pages 137 and 141 of this issue, Cadiau et al. (2) and Cui et al. (3), respectively, show that microporous materials can be designed to have high adsorption capacity and selectivity for particular hydrocarbons, enabling energy-efficient separation. Author: Jerry Y.

    [Perspective] How to break down crystalline cellulose (2016)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2016-05-27
    Description: Biomass-degrading microorganisms use lytic polysaccharide monooxygenase (LPMO) enzymes to help digest cellulose, chitin, and starch. By cleaving otherwise inaccessible crystalline cellulose chains, these enzymes provide access to hydrolytic enzymes. LPMOs are of interest to biotechnology because efficient depolymerization of cellulose is a major bottleneck for the production of biologically based chemicals and fuels. On page 1098 of this issue, Kracher et al. (1) compare LPMO-reducing substrates in fungi from different taxonomic groups and lifestyles, based on both biochemical and genomic evidence. The results provide insights into reductive activation of LPMO that are important for developing more efficient industrial enzymes for lignocellulose biorefineries. Author: Angel T. Martínez

    Comment on "Selective anaerobic oxidation of methane enables direct synthesis of methanol" (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-02-16
    Description: The comment and response concerning the report of oxidation of methane to methanol by water (Reports, 5 May 2017, p. 523) do not fully capture the implications of thermodynamic limitations. A nonisothermal process in which each cycle requires a large temperature swing and permits only substoichiometric methane conversion surely could not be carried out on any practical scale.

    In: Science
    Details
    Publication Date: 2018-02-16
    Description: Labinger argues that stepwise reaction of methane with water to produce methanol and hydrogen will never be commercially feasible because of its substoichiometric basis with respect to the active site and the requirement of a large temperature swing. This comment is not touching any new ground, beyond describing the thermodynamic feasibility, thermal cycling, and the role of water as discussed previously. Most important, it does not have a solid numerical basis.

    Teaching an old carbocation new tricks: Intermolecular C-H insertion reactions of vinyl cations (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-07-27
    Description: Vinyl carbocations have been the subject of extensive experimental and theoretical studies over the past five decades. Despite this long history in chemistry, the utility of vinyl cations in chemical synthesis has been limited, with most reactivity studies focusing on solvolysis reactions or intramolecular processes. Here we report synthetic and mechanistic studies of vinyl cations generated through silylium–weakly coordinating anion catalysis. We find that these reactive intermediates undergo mild intermolecular carbon-carbon bond–forming reactions, including carbon-hydrogen (C–H) insertion into unactivated sp 3 C–H bonds and reductive Friedel-Crafts reactions with arenes. Moreover, we conducted computational studies of these alkane C–H functionalization reactions and discovered that they proceed through nonclassical, ambimodal transition structures. This reaction manifold provides a framework for the catalytic functionalization of hydrocarbons using simple ketone derivatives.

    Separation of enantiomers by their enantiospecific interaction with achiral magnetic substrates (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-06-22
    Description: It is commonly assumed that recognition and discrimination of chirality, both in nature and in artificial systems, depend solely on spatial effects. However, recent studies have suggested that charge redistribution in chiral molecules manifests an enantiospecific preference in electron spin orientation. We therefore reasoned that the induced spin polarization may affect enantiorecognition through exchange interactions. Here we show experimentally that the interaction of chiral molecules with a perpendicularly magnetized substrate is enantiospecific. Thus, one enantiomer adsorbs preferentially when the magnetic dipole is pointing up, whereas the other adsorbs faster for the opposite alignment of the magnetization. The interaction is not controlled by the magnetic field per se, but rather by the electron spin orientations, and opens prospects for a distinct approach to enantiomeric separations.

    Observation of the geometric phase effect in the H + HD -〉 H2 + D reaction (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-12-14
    Description: Theory has established the importance of geometric phase (GP) effects in the adiabatic dynamics of molecular systems with a conical intersection connecting the ground- and excited-state potential energy surfaces, but direct observation of their manifestation in chemical reactions remains a major challenge. Here, we report a high-resolution crossed molecular beams study of the H + HD -〉 H 2 + D reaction at a collision energy slightly above the conical intersection. Velocity map ion imaging revealed fast angular oscillations in product quantum state–resolved differential cross sections in the forward scattering direction for H 2 products at specific rovibrational levels. The experimental results agree with adiabatic quantum dynamical calculations only when the GP effect is included.

    Stereodivergent synthesis of 1,4-dicarbonyls by traceless charge-accelerated sulfonium rearrangement (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-08-17
    Description: The chemistry of the carbonyl group is essential to modern organic synthesis. The preparation of substituted, enantioenriched 1,3- or 1,5-dicarbonyls is well developed, as their disconnection naturally follows from the intrinsic polarity of the carbonyl group. By contrast, a general enantioselective access to quaternary stereocenters in acyclic 1,4-dicarbonyl systems remains an unresolved problem, despite the tremendous importance of 2,3-substituted 1,4-dicarbonyl motifs in natural products and drug scaffolds. Here we present a broad enantioselective and stereodivergent strategy to access acyclic, polysubstituted 1,4-dicarbonyls via acid-catalyzed [3,3]-sulfonium rearrangement starting from vinyl sulfoxides and ynamides. The stereochemistry at sulfur governs the absolute sense of chiral induction, whereas the double bond geometry dictates the relative configuration of the final products.

    Selective functionalization of methane, ethane, and higher alkanes by cerium photocatalysis (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-08-17
    Description: With the recent soaring production of natural gas, the use of methane and other light hydrocarbon feedstocks as starting materials in synthetic transformations is becoming increasingly economically attractive, although it remains chemically challenging. We report the development of photocatalytic C–H amination, alkylation, and arylation of methane, ethane, and higher alkanes under visible light irradiation at ambient temperature. High catalytic efficiency (turnover numbers up to 2900 for methane and 9700 for ethane) and selectivity were achieved using abundant, inexpensive cerium salts as photocatalysts. Ligand-to-metal charge transfer excitation generated alkoxy radicals from simple alcohols that in turn acted as hydrogen atom transfer catalysts. The mixed-phase gas/liquid reaction was adapted to continuous flow, enabling the efficient use of gaseous feedstocks in scalable photocatalytic transformations.

    Directional control of a processive molecular hopper (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-08-31
    Description: Intrigued by the potential of nanoscale machines, scientists have long attempted to control molecular motion. We monitored the individual 0.7-nanometer steps of a single molecular hopper as it moved in an electric field along a track in a nanopore controlled by a chemical ratchet. The hopper demonstrated characteristics desired in a moving molecule: defined start and end points, processivity, no chemical fuel requirement, directional motion, and external control. The hopper was readily functionalized to carry cargos. For example, a DNA molecule could be ratcheted along the track in either direction, a prerequisite for nanopore sequencing.

    Unlocking P(V): Reagents for chiral phosphorothioate synthesis (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-09-21
    Description: Phosphorothioate nucleotides have emerged as powerful pharmacological substitutes of their native phosphodiester analogs with important translational applications in antisense oligonucleotide (ASO) therapeutics and cyclic dinucleotide (CDN) synthesis. Stereocontrolled installation of this chiral motif has long been hampered by the systemic use of phosphorus(III) [P(III)]–based reagent systems as the sole practical means of oligonucleotide assembly. A fundamentally different approach is described herein: the invention of a P(V)-based reagent platform for programmable, traceless, diastereoselective phosphorus-sulfur incorporation. The power of this reagent system is demonstrated through the robust and stereocontrolled synthesis of various nucleotidic architectures, including ASOs and CDNs, via an efficient, inexpensive, and operationally simple protocol.

    Self-assembly of lattices with high structural complexity from a geometrically simple molecule (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-09-21
    Description: Here we report an anomalous porous molecular crystal built of C–H···N-bonded double-layered roof-floor components and wall components of a segregatively interdigitated architecture. This complicated porous structure consists of only one type of fully aromatic multijoint molecule carrying three identical dipyridylphenyl wedges. Despite its high symmetry, this molecule accomplishes difficult tasks by using two of its three wedges for roof-floor formation and using its other wedge for wall formation. Although a C–H···N bond is extremely labile, the porous crystal maintains its porosity until thermal breakdown of the C–H···N bonds at 202°C occurs, affording a nonporous polymorph. Though this nonporous crystal survives even at 325°C, it can retrieve the parent porosity under acetonitrile vapor. These findings show how one can translate simplicity into ultrahigh complexity.

    Interrupted carbonyl-olefin metathesis via oxygen atom transfer (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-09-28
    Description: Some of the simplest and most powerful carbon-carbon bond forming strategies take advantage of readily accessible ubiquitous motifs: carbonyls and olefins. Here we report a fundamentally distinct mode of reactivity between carbonyls and olefins that differs from established acid-catalyzed carbonyl-ene, Prins, and carbonyl-olefin metathesis reaction paths. A range of epsilon, zeta-unsaturated ketones undergo Brønsted acid–catalyzed intramolecular cyclization to provide tetrahydrofluorene products via the formation of two new carbon-carbon bonds. Theoretical calculations and accompanying mechanistic studies suggest that this carbocyclization reaction proceeds through the intermediacy of a transient oxetane formed by oxygen atom transfer. The complex polycyclic frameworks in this product class appear as common substructures in organic materials, bioactive natural products, and recently developed pharmaceuticals.

    Arylsulfonylacetamides as bifunctional reagents for alkene aminoarylation (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-09-28
    Description: Alkene aminoarylation with a single, bifunctional reagent is a concise synthetic strategy. We report a catalytic protocol for the addition of arylsulfonylacetamides across electron-rich alkenes with complete anti-Markovnikov regioselectivity and excellent diastereoselectivity to provide 2,2-diarylethylamines. In this process, single-electron alkene oxidation enables carbon-nitrogen bond formation to provide a key benzylic radical poised for a Smiles-Truce 1,5-aryl shift. This reaction is redox-neutral, exhibits broad functional group compatibility, and occurs at room temperature with loss of sulfur dioxide. As this process is driven by visible light, uses readily available starting materials, and demonstrates convergent synthesis, it is well suited for use in a variety of synthetic endeavors.

    Quantifying hot carrier and thermal contributions in plasmonic photocatalysis (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-10-05
    Description: Photocatalysis based on optically active, "plasmonic" metal nanoparticles has emerged as a promising approach to facilitate light-driven chemical conversions under far milder conditions than thermal catalysis. However, an understanding of the relation between thermal and electronic excitations has been lacking. We report the substantial light-induced reduction of the thermal activation barrier for ammonia decomposition on a plasmonic photocatalyst. We introduce the concept of a light-dependent activation barrier to account for the effect of light illumination on electronic and thermal excitations in a single unified picture. This framework provides insight into the specific role of hot carriers in plasmon-mediated photochemistry, which is critically important for designing energy-efficient plasmonic photocatalysts.

    Ketyl radical reactivity via atom transfer catalysis (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-10-12
    Description: Single-electron reduction of a carbonyl to a ketyl enables access to a polarity-reversed platform of reactivity for this cornerstone functional group. However, the synthetic utility of the ketyl radical is hindered by the strong reductants necessary for its generation, which also limit its reactivity to net reductive mechanisms. We report a strategy for net redox-neutral generation and reaction of ketyl radicals. The in situ conversion of aldehydes to α-acetoxy iodides lowers their reduction potential by more than 1 volt, allowing for milder access to the corresponding ketyl radicals and an oxidative termination event. Upon subjecting these iodides to a dimanganese decacarbonyl precatalyst and visible light irradiation, an atom transfer radical addition (ATRA) mechanism affords a broad scope of vinyl iodide products with high Z -selectivity.

    Confined acids catalyze asymmetric single aldolizations of acetaldehyde enolates (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-10-12
    Description: Reactions that form a product with the same reactive functionality as that of one of the starting compounds frequently end in oligomerization. As a salient example, selective aldol coupling of the smallest, though arguably most useful, enolizable aldehyde, acetaldehyde, with just one partner substrate has proven to be extremely challenging. Here, we report a highly enantioselective Mukaiyama aldol reaction with the simple triethylsilyl (TES) and tert -butyldimethylsilyl (TBS) enolates of acetaldehyde and various aliphatic and aromatic acceptor aldehydes. The reaction is catalyzed by recently developed, strongly acidic imidodiphosphorimidates (IDPi), which, like enzymes, display a confined active site but, like small-molecule catalysts, have a broad substrate scope. The process is scalable, fast, efficient (0.5 to 1.5 mole % catalyst loading), and greatly simplifies access to highly valuable silylated acetaldehyde aldols.

    Magnetic hysteresis up to 80 kelvin in a dysprosium metallocene single-molecule magnet (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-12-21
    Description: Single-molecule magnets (SMMs) containing only one metal center may represent the lower size limit for molecule-based magnetic information storage materials. Their current drawback is that all SMMs require liquid-helium cooling to show magnetic memory effects. We now report a chemical strategy to access the dysprosium metallocene cation [(Cp i Pr5 )Dy(Cp*)] + (Cp i Pr5 , penta-iso-propylcyclopentadienyl; Cp *, pentamethylcyclopentadienyl), which displays magnetic hysteresis above liquid-nitrogen temperatures. An effective energy barrier to reversal of the magnetization of U eff = 1541 wave number is also measured. The magnetic blocking temperature of T B = 80 kelvin for this cation overcomes an essential barrier toward the development of nanomagnet devices that function at practical temperatures.

    Details
    Publication Date: 2006-03-04
    Description: Human beings routinely help others to achieve their goals, even when the helper receives no immediate benefit and the person helped is a stranger. Such altruistic behaviors (toward non-kin) are extremely rare evolutionarily, with some theorists even proposing that they are uniquely human. Here we show that human children as young as 18 months of age (prelinguistic or just-linguistic) quite readily help others to achieve their goals in a variety of different situations. This requires both an understanding of others' goals and an altruistic motivation to help. In addition, we demonstrate similar though less robust skills and motivations in three young chimpanzees.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warneken, Felix -- Tomasello, Michael -- New York, N.Y. -- Science. 2006 Mar 3;311(5765):1301-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental and Comparative Psychology, Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany. warneken@eva.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16513986" target="_blank"〉PubMed〈/a〉

    An antigen produced by splicing of noncontiguous peptides in the reverse order (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-09
    Description: CD8-positive T lymphocytes recognize peptides that are usually derived from the degradation of cellular proteins and are presented by class I molecules of the major histocompatibility complex. Here we describe a human minor histocompatibility antigen created by a polymorphism in the SP110 nuclear phosphoprotein gene. The antigenic peptide comprises two noncontiguous SP110 peptide segments spliced together in reverse order to that in which they occur in the predicted SP110 protein. The antigenic peptide could be produced in vitro by incubation of precursor peptides with highly purified 20S proteasomes. Cutting and splicing probably occur within the proteasome by transpeptidation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Edus H -- Vigneron, Nathalie J -- Gavin, Marc A -- Coulie, Pierre G -- Stroobant, Vincent -- Dalet, Alexandre -- Tykodi, Scott S -- Xuereb, Suzanne M -- Mito, Jeffrey K -- Riddell, Stanley R -- Van den Eynde, Benoit J -- CA106512/CA/NCI NIH HHS/ -- CA18029/CA/NCI NIH HHS/ -- P01 CA018029/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1444-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Immunology, Clinical Research Division, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960008" target="_blank"〉PubMed〈/a〉

    Description: Medical imaging technologies have undergone explosive growth over the past few decades and now play a central role in clinical oncology. But the truly transformative power of imaging in the clinical management of cancer patients lies ahead. Today, imaging is at a crossroads, with molecularly targeted imaging agents expected to broadly expand the capabilities of conventional anatomical imaging methods. Molecular imaging will allow clinicians to not only see where a tumor is located in the body, but also to visualize the expression and activity of specific molecules (e.g., proteases and protein kinases) and biological processes (e.g., apoptosis, angiogenesis, and metastasis) that influence tumor behavior and/or response to therapy. This information is expected to have a major impact on cancer detection, individualized treatment, and drug development, as well as our understanding of how cancer arises.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weissleder, Ralph -- New York, N.Y. -- Science. 2006 May 26;312(5777):1168-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Imaging Research, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA. weissleder@helix.mgh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728630" target="_blank"〉PubMed〈/a〉

    Language control in the bilingual brain (2006)

    Details
    Publication Date: 2006-06-10
    Description: How does the bilingual brain distinguish and control which language is in use? Previous functional imaging experiments have not been able to answer this question because proficient bilinguals activate the same brain regions irrespective of the language being tested. Here, we reveal that neuronal responses within the left caudate are sensitive to changes in the language or the meaning of words. By demonstrating this effect in populations of German-English and Japanese-English bilinguals, we suggest that the left caudate plays a universal role in monitoring and controlling the language in use.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crinion, J -- Turner, R -- Grogan, A -- Hanakawa, T -- Noppeney, U -- Devlin, J T -- Aso, T -- Urayama, S -- Fukuyama, H -- Stockton, K -- Usui, K -- Green, D W -- Price, C J -- 051067/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Jun 9;312(5779):1537-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Department of Imaging Neuroscience, University College London, London WC1N 3BG, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16763154" target="_blank"〉PubMed〈/a〉

    A clamping mechanism involved in SNARE-dependent exocytosis (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-24
    Description: During neurotransmitter release at the synapse, influx of calcium ions stimulates the release of neurotransmitter. However, the mechanism by which synaptic vesicle fusion is coupled to calcium has been unclear, despite the identification of both the core fusion machinery [soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)] and the principal calcium sensor (synaptotagmin). Here, we describe what may represent a basic principle of the coupling mechanism: a reversible clamping protein (complexin) that can freeze the SNAREpin, an assembled fusion-competent intermediate en route to fusion. When calcium binds to the calcium sensor synaptotagmin, the clamp would then be released. SNARE proteins, and key regulators like synaptotagmin and complexin, can be ectopically expressed on the cell surface. Cells expressing such "flipped" synaptic SNAREs fuse constitutively, but when we coexpressed complexin, fusion was blocked. Adding back calcium triggered fusion from this intermediate in the presence of synaptotagmin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giraudo, Claudio G -- Eng, William S -- Melia, Thomas J -- Rothman, James E -- New York, N.Y. -- Science. 2006 Aug 4;313(5787):676-80.

    Group competition, reproductive leveling, and the evolution of human altruism (2006)

    Details
    Publication Date: 2006-12-13
    Description: Humans behave altruistically in natural settings and experiments. A possible explanation-that groups with more altruists survive when groups compete-has long been judged untenable on empirical grounds for most species. But there have been no empirical tests of this explanation for humans. My empirical estimates show that genetic differences between early human groups are likely to have been great enough so that lethal intergroup competition could account for the evolution of altruism. Crucial to this process were distinctive human practices such as sharing food beyond the immediate family, monogamy, and other forms of reproductive leveling. These culturally transmitted practices presuppose advanced cognitive and linguistic capacities, possibly accounting for the distinctive forms of altruism found in our species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2006 Dec 8;314(5805):1569-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA, and Universita di Siena, 17 Piazza San Francesco, Siena, Italy. bowles@santafe.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17158320" target="_blank"〉PubMed〈/a〉

    Description: One hundred years ago a small group of psychiatrists described the abnormal protein deposits in the brain that define the most common neurodegenerative diseases. Over the past 25 years, it has become clear that the proteins forming the deposits are central to the disease process. Amyloid-beta and tau make up the plaques and tangles of Alzheimer's disease, where these normally soluble proteins assemble into amyloid-like filaments. Tau inclusions are also found in a number of related disorders. Genetic studies have shown that dysfunction of amyloid-beta or tau is sufficient to cause dementia. The ongoing molecular dissection of the neurodegenerative pathways is expected to lead to a true understanding of disease pathogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goedert, Michel -- Spillantini, Maria Grazia -- G0301152/Medical Research Council/United Kingdom -- MC_U105184291/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 Nov 3;314(5800):777-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Biology, Medical Research Council, Cambridge CB2 2QH, UK. mg@mrc-lmb.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17082447" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-14
    Description: Plants produce many volatile metabolites. A small subset of these compounds is sensed by animals and humans, and the volatile profiles are defining elements of the distinct flavors of individual foods. Flavor volatiles are derived from an array of nutrients, including amino acids, fatty acids, and carotenoids. In tomato, almost all of the important flavor-related volatiles are derived from essential nutrients. The predominance of volatiles derived from essential nutrients and health-promoting compounds suggests that these volatiles provide important information about the nutritional makeup of foods. Evidence supporting a relation between volatile perception and nutrient or health value will be reviewed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goff, Stephen A -- Klee, Harry J -- New York, N.Y. -- Science. 2006 Feb 10;311(5762):815-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Syngenta Fellows Group, Syngenta Biotechnology Inc., 3054 Cornwallis Road, Research Triangle Park, NC 27709-2257, USA. stephen.goff@syngenta.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16469919" target="_blank"〉PubMed〈/a〉

    A virulence locus of Pseudomonas aeruginosa encodes a protein secretion apparatus (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-10
    Description: Bacterial pathogens frequently use protein secretion to mediate interactions with their hosts. Here we found that a virulence locus (HSI-I) of Pseudomonas aeruginosa encodes a protein secretion apparatus. The apparatus assembled in discrete subcellular locations and exported Hcp1, a hexameric protein that forms rings with a 40 angstrom internal diameter. Regulatory patterns of HSI-I suggested that the apparatus functions during chronic infections. We detected Hcp1 in pulmonary secretions of cystic fibrosis (CF) patients and Hcp1-specific antibodies in their sera. Thus, HSI-I likely contributes to the pathogenesis of P. aeruginosa in CF patients. HSI-I-related loci are widely distributed among bacterial pathogens and may play a general role in mediating host interactions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2800167/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2800167/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mougous, Joseph D -- Cuff, Marianne E -- Raunser, Stefan -- Shen, Aimee -- Zhou, Min -- Gifford, Casey A -- Goodman, Andrew L -- Joachimiak, Grazyna -- Ordonez, Claudia L -- Lory, Stephen -- Walz, Thomas -- Joachimiak, Andrzej -- Mekalanos, John J -- AI21451/AI/NIAID NIH HHS/ -- AI26289/AI/NIAID NIH HHS/ -- GM074942/GM/NIGMS NIH HHS/ -- GM62414/GM/NIGMS NIH HHS/ -- P50 GM062414/GM/NIGMS NIH HHS/ -- P50 GM062414-02/GM/NIGMS NIH HHS/ -- U54 GM074942/GM/NIGMS NIH HHS/ -- U54 GM074942-04S2/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jun 9;312(5779):1526-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Molecular Genetics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16763151" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2006-04-22
    Description: Given the considerable challenges to the rapid development of an effective vaccine against influenza, antiviral agents will play an important role as a first-line defense if a new pandemic occurs. The large-scale use of drugs for chemoprophylaxis and treatment will impose strong selection for the evolution of drug-resistant strains. The ensuing transmission of those strains could substantially limit the effectiveness of the drugs as a first-line defense. Summarizing recent data on the rate at which the treatment of influenza infection generates resistance de novo and on the transmission fitness of resistant virus, we discuss possible implications for the epidemiological spread of drug resistance in the context of an established population dynamic model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regoes, Roland R -- Bonhoeffer, Sebastian -- New York, N.Y. -- Science. 2006 Apr 21;312(5772):389-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Integrative Biology, ETH Zurich, ETH Zentrum CHN K12.1, Universitatsstrasse 16, CH 8092 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16627735" target="_blank"〉PubMed〈/a〉

    Description: The allure of the emerging genomic technologies in cancer is their ability to generate new biomarkers that predict how individual cancer patients will respond to various treatments. However, productive implementation of cancer biomarkers into patient care will require fundamental changes in how we consider approvals for cancer indications and how we track patient responses. Here we briefly describe ongoing efforts to identify and to validate cancer biomarkers, discuss the technological hurdles that lie ahead, and then focus on the more pressing political and cultural issues that, if left unheeded, could derail many of the anticipated benefits of biomarker research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dalton, William S -- Friend, Stephen H -- New York, N.Y. -- Science. 2006 May 26;312(5777):1165-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉H.

    Description: Kislev et al. (Reports, 2 June 2006, p. 1372) described Neolithic parthenocarpic fig fruits and proposed that they derive from trees propagated only by cuttings and thus represent the first domesticated plant of the Neolithic Revolution. Because parthenocarpic fig trees naturally produce both seeded and seedless fruits and are capable of spontaneous reproduction, we argue that the finds do not necessarily indicate cultivation, nor horticulture predating grain crops.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lev-Yadun, Simcha -- Ne'eman, Gidi -- Abbo, Shahal -- Flaishman, Moshe A -- New York, N.Y. -- Science. 2006 Dec 15;314(5806):1683; author reply 1683.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Faculty of Science and Science Education, University of Haifa-Oranim, Tivon 36006, Israel. levyadun@research.haifa.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17170278" target="_blank"〉PubMed〈/a〉

    Genetic variation affects de novo translocation frequency (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-18
    Description: Translocation is one of the most frequently occurring human chromosomal aberrations. The constitutional t(11;22)(q23;q11), which is the only known recurrent non-Robertsonian translocation, represents a good model for studying translocations in humans. Here we demonstrate polymorphisms of the palindromic sequence at the t(11;22) breakpoint that affect the frequency of de novo translocations in sperm from normal males. A typical allele consists of a perfect palindrome, producing ~10-5 de novo t(11;22) translocations. Alleles with an asymmetric center do not form the t(11;22). Our data show the importance of genome sequence on chromosomal rearrangements, a class of human mutation that is thought to be random.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818512/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818512/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kato, Takema -- Inagaki, Hidehito -- Yamada, Kouji -- Kogo, Hiroshi -- Ohye, Tamae -- Kowa, Hiroe -- Nagaoka, Kayuri -- Taniguchi, Mariko -- Emanuel, Beverly S -- Kurahashi, Hiroki -- CA39926/CA/NCI NIH HHS/ -- P01 DC002027/DC/NIDCD NIH HHS/ -- P01 DC002027-070006/DC/NIDCD NIH HHS/ -- R01 CA039926/CA/NCI NIH HHS/ -- R01 CA039926-18/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):971.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Genetics, Institute for Comprehensive Medical Science, Fujita Health University, 1-98 Dengakugakubo, Kutsukake-cho, Toyoake Aichi 470-1192, Japan [corrected]〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484486" target="_blank"〉PubMed〈/a〉

    Molecular linkage between the kinase ATM and NF-kappaB signaling in response to genotoxic stimuli (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-25
    Description: The transcription factor NF-kappaB modulates apoptotic responses induced by genotoxic stress. We show that NF-kappaB essential modulator (NEMO), the regulatory subunit of IkappaB kinase (IKK) (which phosphorylates the NF-kappaB inhibitor IkappaB), associates with activated ataxia telangiectasia mutated (ATM) after the induction of DNA double-strand breaks. ATM phosphorylates serine-85 of NEMO to promote its ubiquitin-dependent nuclear export. ATM is also exported in a NEMO-dependent manner to the cytoplasm, where it associates with and causes the activation of IKK in a manner dependent on another IKK regulator, a protein rich in glutamate, leucine, lysine, and serine (ELKS). Thus, regulated nuclear shuttling of NEMO links two signaling kinases, ATM and IKK, to activate NF-kappaB by genotoxic signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Zhao-Hui -- Shi, Yuling -- Tibbetts, Randal S -- Miyamoto, Shigeki -- R01-CA77474/CA/NCI NIH HHS/ -- R01-CA81065/CA/NCI NIH HHS/ -- R01-GM067868/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Feb 24;311(5764):1141-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Wisconsin-Madison, 301 SMI, 1300 University Avenue, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16497931" target="_blank"〉PubMed〈/a〉

    Description: Nisin is a posttranslationally modified antimicrobial peptide that is widely used as a food preservative. It contains five cyclic thioethers of varying sizes that are installed by a single enzyme, NisC. Reported here are the in vitro reconstitution of the cyclization process and the x-ray crystal structure of the NisC enzyme. The structure reveals similarities in fold and substrate activation with mammalian farnesyl transferases, suggesting that human homologs of NisC posttranslationally modify a cysteine of a protein substrate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Bo -- Yu, John Paul J -- Brunzelle, Joseph S -- Moll, Gert N -- van der Donk, Wilfred A -- Nair, Satish K -- GM58822/GM/NIGMS NIH HHS/ -- R01 GM079038/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 10;311(5766):1464-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Illinois at Urbana-Champaign, 600 South Mathews Avenue, Urbana, IL 61801, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16527981" target="_blank"〉PubMed〈/a〉

    A regulatory SNP causes a human genetic disease by creating a new transcriptional promoter (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-05-27
    Description: We describe a pathogenetic mechanism underlying a variant form of the inherited blood disorder alpha thalassemia. Association studies of affected individuals from Melanesia localized the disease trait to the telomeric region of human chromosome 16, which includes the alpha-globin gene cluster, but no molecular defects were detected by conventional approaches. After resequencing and using a combination of chromatin immunoprecipitation and expression analysis on a tiled oligonucleotide array, we identified a gain-of-function regulatory single-nucleotide polymorphism (rSNP) in a nongenic region between the alpha-globin genes and their upstream regulatory elements. The rSNP creates a new promoterlike element that interferes with normal activation of all downstream alpha-like globin genes. Thus, our work illustrates a strategy for distinguishing between neutral and functionally important rSNPs, and it also identifies a pathogenetic mechanism that could potentially underlie other genetic diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Gobbi, Marco -- Viprakasit, Vip -- Hughes, Jim R -- Fisher, Chris -- Buckle, Veronica J -- Ayyub, Helena -- Gibbons, Richard J -- Vernimmen, Douglas -- Yoshinaga, Yuko -- de Jong, Pieter -- Cheng, Jan-Fang -- Rubin, Edward M -- Wood, William G -- Bowden, Don -- Higgs, Douglas R -- MC_U137961143/Medical Research Council/United Kingdom -- MC_U137961145/Medical Research Council/United Kingdom -- MC_U137961147/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2006 May 26;312(5777):1215-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Molecular Haematology Unit, Weatherall Institute of Molecular Medicine, John Radcliffe Hospital, Oxford, OX3 9DS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16728641" target="_blank"〉PubMed〈/a〉

    Long-distance dispersal of plants (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the standard dispersal vectors and the mean trend of the distribution of dispersal distances. "Nonstandard" mechanisms such as extreme climatic events and generalized LDD vectors seem to hold the greatest explanatory power for the drastic deviations from the mean trend, deviations that make the nearly impossible LDD a reality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nathan, Ran -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):786-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Movement Ecology Laboratory, Department of Evolution, Systematics and Ecology, Alexander Silberman Institute of Life Sciences, Hebrew University of Jerusalem, Givat Ram, 91904 Jerusalem, Israel. rnathan@cc.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902126" target="_blank"〉PubMed〈/a〉

    HIV decline associated with behavior change in eastern Zimbabwe (2006)

    Details
    Publication Date: 2006-02-04
    Description: Few sub-Saharan African countries have witnessed declines in HIV prevalence, and only Uganda has compelling evidence for a decline founded on sexual behavior change. We report a decline in HIV prevalence in eastern Zimbabwe between 1998 and 2003 associated with sexual behavior change in four distinct socioeconomic strata. HIV prevalence fell most steeply at young ages-by 23 and 49%, respectively, among men aged 17 to 29 years and women aged 15 to 24 years-and in more educated groups. Sexually experienced men and women reported reductions in casual sex of 49 and 22%, respectively, whereas recent cohorts reported delayed sexual debut. Selective AIDS-induced mortality contributed to the decline in HIV prevalence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregson, Simon -- Garnett, Geoffrey P -- Nyamukapa, Constance A -- Hallett, Timothy B -- Lewis, James J C -- Mason, Peter R -- Chandiwana, Stephen K -- Anderson, Roy M -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2006 Feb 3;311(5761):664-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Infectious Disease Epidemiology, Imperial College London, UK.

    Human hair growth deficiency is linked to a genetic defect in the phospholipase gene LIPH (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-11-11
    Description: The molecular mechanisms controlling human hair growth and scalp hair loss are poorly understood. By screening about 350,000 individuals in two populations from the Volga-Ural region of Russia, we identified a gene mutation in families who show an inherited form of hair loss and a hair growth defect. Affected individuals were homozygous for a deletion in the LIPH gene on chromosome 3q27, caused by short interspersed nuclear element-retrotransposon-mediated recombination. The LIPH gene is expressed in hair follicles and encodes a phospholipase called lipase H (alternatively known as membrane-associated phosphatidic acid-selective phospholipase A1alpha), an enzyme that regulates the production of bioactive lipids. These results suggest that lipase H participates in hair growth and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kazantseva, Anastasiya -- Goltsov, Andrey -- Zinchenko, Rena -- Grigorenko, Anastasia P -- Abrukova, Anna V -- Moliaka, Yuri K -- Kirillov, Alexander G -- Guo, Zhiru -- Lyle, Stephen -- Ginter, Evgeny K -- Rogaev, Evgeny I -- K08-AR02179/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Nov 10;314(5801):982-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brudnick Neuropsychiatric Research Institute, Department of Psychiatry, University of Massachusetts Medical School, 303 Belmont Street, Worcester, MA 01604, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17095700" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-08-12
    Description: Theoretical work suggests that structural properties of naturally occurring networks are important in shaping behavior and dynamics. However, the relationships between structure and behavior are difficult to establish through empirical studies, because the networks in such studies are typically fixed. We studied networks of human subjects attempting to solve the graph or network coloring problem, which models settings in which it is desirable to distinguish one's behavior from that of one's network neighbors. Networks generated by preferential attachment made solving the coloring problem more difficult than did networks based on cyclical structures, and "small worlds" networks were easier still. We also showed that providing more information can have opposite effects on performance, depending on network structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kearns, Michael -- Suri, Siddharth -- Montfort, Nick -- New York, N.Y. -- Science. 2006 Aug 11;313(5788):824-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of Pennsylvania, Department of Computer and Information Science, 3330 Walnut Street, Philadelphia, PA 19104, USA. mkearns@cis.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16902134" target="_blank"〉PubMed〈/a〉

    Some frontiers in social science (2006)

    Publication Date: 2006-07-01
    Description: The fundamental challenge in the social sciences is moving from complicated correlations to useful prediction. Progress usually reflects an interplay between theory, data, and tools. Six areas of innovation, principally data and tools, are now pushing at the frontiers of these sciences: longitudinal data, laboratory experimentation, improved statistical methods, geographic information tools, biosocial science, and international replication. These innovations are gaining power as they cross disciplinary boundaries, helping to attribute causality to observed relationships, to understand their nature, and thereby to improve the accuracy and usefulness of predictions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butz, William P -- Torrey, Barbara Boyle -- New York, N.Y. -- Science. 2006 Jun 30;312(5782):1898-900.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Population Reference Bureau, 1875 Connecticut Avenue, Washington, DC 20009, USA. wbutz@prb.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16809524" target="_blank"〉PubMed〈/a〉
