Description: A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three replicate. Estimated effects sizes are small (coefficient of determination R(2) approximately 0.02%), approximately 1 month of schooling per allele. A linear polygenic score from all measured SNPs accounts for approximately 2% of the variance in both educational attainment and cognitive function. Genes in the region of the loci have previously been associated with health, cognitive, and central nervous system phenotypes, and bioinformatics analyses suggest the involvement of the anterior caudate nucleus. These findings provide promising candidate SNPs for follow-up work, and our effect size estimates can anchor power analyses in social-science genetics.〈br /〉〈br /〉〈a

Description: The Fermi Gamma-ray Space Telescope has detected the gamma-ray glow emanating from the giant radio lobes of the radio galaxy Centaurus A. The resolved gamma-ray image shows the lobes clearly separated from the central active source. In contrast to all other active galaxies detected so far in high-energy gamma-rays, the lobe flux constitutes a considerable portion (greater than one-half) of the total source emission. The gamma-ray emission from the lobes is interpreted as inverse Compton-scattered relic radiation from the cosmic microwave background, with additional contribution at higher energies from the infrared-to-optical extragalactic background light. These measurements provide gamma-ray constraints on the magnetic field and particle energy content in radio galaxy lobes, as well as a promising method to probe the cosmic relic photon fields.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fermi-LAT Collaboration -- Abdo, A A -- Ackermann, M -- Ajello, M -- Atwood, W B -- Baldini, L -- Ballet, J -- Barbiellini, G -- Bastieri, D -- Baughman, B M -- Bechtol, K -- Bellazzini, R -- Berenji, B -- Blandford, R D -- Bloom, E D -- Bonamente, E -- Borgland, A W -- Bregeon, J -- Brez, A -- Brigida, M -- Bruel, P -- Burnett, T H -- Buson, S -- Caliandro, G A -- Cameron, R A -- Caraveo, P A -- Casandjian, J M -- Cavazzuti, E -- Cecchi, C -- Celik, O -- Chekhtman, A -- Cheung, C C -- Chiang, J -- Ciprini, S -- Claus, R -- Cohen-Tanugi, J -- Colafrancesco, S -- Cominsky, L R -- Conrad, J -- Costamante, L -- Cutini, S -- Davis, D S -- Dermer, C D -- de Angelis, A -- de Palma, F -- Digel, S W -- do Couto e Silva, E -- Drell, P S -- Dubois, R -- Dumora, D -- Farnier, C -- Favuzzi, C -- Fegan, S J -- Finke, J -- Focke, W B -- Fortin, P -- Fukazawa, Y -- Funk, S -- Fusco, P -- Gargano, F -- Gasparrini, D -- Gehrels, N -- Georganopoulos, M -- Germani, S -- Giebels, B -- Giglietto, N -- Giordano, F -- Giroletti, M -- Glanzman, T -- Godfrey, G -- Grenier, I A -- Grove, J E -- Guillemot, L -- Guiriec, S -- Hanabata, Y -- Harding, A K -- Hayashida, M -- Hays, E -- Hughes, R E -- Jackson, M S -- Johannesson, G -- Johnson, A S -- Johnson, T J -- Johnson, W N -- Kamae, T -- Katagiri, H -- Kataoka, J -- Kawai, N -- Kerr, M -- Knodlseder, J -- Kocian, M L -- Kuss, M -- Lande, J -- Latronico, L -- Lemoine-Goumard, M -- Longo, F -- Loparco, F -- Lott, B -- Lovellette, M N -- Lubrano, P -- Madejski, G M -- Makeev, A -- Mazziotta, M N -- McConville, W -- McEnery, J E -- Meurer, C -- Michelson, P F -- Mitthumsiri, W -- Mizuno, T -- Moiseev, A A -- Monte, C -- Monzani, M E -- Morselli, A -- Moskalenko, I V -- Murgia, S -- Nolan, P L -- Norris, J P -- Nuss, E -- Ohsugi, T -- Omodei, N -- Orlando, E -- Ormes, J F -- Paneque, D -- Parent, D -- Pelassa, V -- Pepe, M -- Pesce-Rollins, M -- Piron, F -- Porter, T A -- Raino, S -- Rando, R -- Razzano, M -- Razzaque, S -- Reimer, A -- Reimer, O -- Reposeur, T -- Ritz, S -- Rochester, L S -- Rodriguez, A Y -- Romani, R W -- Roth, M -- Ryde, F -- Sadrozinski, H F-W -- Sambruna, R -- Sanchez, D -- Sander, A -- Saz Parkinson, P M -- Scargle, J D -- Sgro, C -- Siskind, E J -- Smith, D A -- Smith, P D -- Spandre, G -- Spinelli, P -- Starck, J-L -- Stawarz, L -- Strickman, M S -- Suson, D J -- Tajima, H -- Takahashi, H -- Takahashi, T -- Tanaka, T -- Thayer, J B -- Thayer, J G -- Thompson, D J -- Tibaldo, L -- Torres, D F -- Tosti, G -- Tramacere, A -- Uchiyama, Y -- Usher, T L -- Vasileiou, V -- Vilchez, N -- Vitale, V -- Waite, A P -- Wallace, E -- Wang, P -- Winer, B L -- Wood, K S -- Ylinen, T -- Ziegler, M -- Hardcastle, M J -- Kazanas, D -- New York, N.Y. -- Science. 2010 May 7;328(5979):725-9. doi: 10.1126/science.1184656.

Description: Novae are thermonuclear explosions on a white dwarf surface fueled by mass accreted from a companion star. Current physical models posit that shocked expanding gas from the nova shell can produce x-ray emission, but emission at higher energies has not been widely expected. Here, we report the Fermi Large Area Telescope detection of variable gamma-ray emission (0.1 to 10 billion electron volts) from the recently detected optical nova of the symbiotic star V407 Cygni. We propose that the material of the nova shell interacts with the dense ambient medium of the red giant primary and that particles can be accelerated effectively to produce pi(0) decay gamma-rays from proton-proton interactions. Emission involving inverse Compton scattering of the red giant radiation is also considered and is not ruled out.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fermi-LAT Collaboration -- Abdo, A A -- Ackermann, M -- Ajello, M -- Atwood, W B -- Baldini, L -- Ballet, J -- Barbiellini, G -- Bastieri, D -- Bechtol, K -- Bellazzini, R -- Berenji, B -- Blandford, R D -- Bloom, E D -- Bonamente, E -- Borgland, A W -- Bouvier, A -- Brandt, T J -- Bregeon, J -- Brez, A -- Brigida, M -- Bruel, P -- Buehler, R -- Burnett, T H -- Buson, S -- Caliandro, G A -- Cameron, R A -- Caraveo, P A -- Carrigan, S -- Casandjian, J M -- Cecchi, C -- Celik, O -- Charles, E -- Chaty, S -- Chekhtman, A -- Cheung, C C -- Chiang, J -- Ciprini, S -- Claus, R -- Cohen-Tanugi, J -- Conrad, J -- Corbel, S -- Corbet, R -- DeCesar, M E -- den Hartog, P R -- Dermer, C D -- de Palma, F -- Digel, S W -- Donato, D -- do Couto e Silva, E -- Drell, P S -- Dubois, R -- Dubus, G -- Dumora, D -- Favuzzi, C -- Fegan, S J -- Ferrara, E C -- Fortin, P -- Frailis, M -- Fuhrmann, L -- Fukazawa, Y -- Funk, S -- Fusco, P -- Gargano, F -- Gasparrini, D -- Gehrels, N -- Germani, S -- Giglietto, N -- Giordano, F -- Giroletti, M -- Glanzman, T -- Godfrey, G -- Grenier, I A -- Grondin, M-H -- Grove, J E -- Guiriec, S -- Hadasch, D -- Harding, A K -- Hayashida, M -- Hays, E -- Healey, S E -- Hill, A B -- Horan, D -- Hughes, R E -- Itoh, R -- Jean, P -- Johannesson, G -- Johnson, A S -- Johnson, R P -- Johnson, T J -- Johnson, W N -- Kamae, T -- Katagiri, H -- Kataoka, J -- Kerr, M -- Knodlseder, J -- Koerding, E -- Kuss, M -- Lande, J -- Latronico, L -- Lee, S-H -- Lemoine-Goumard, M -- Garde, M Llena -- Longo, F -- Loparco, F -- Lott, B -- Lovellette, M N -- Lubrano, P -- Makeev, A -- Mazziotta, M N -- McConville, W -- McEnery, J E -- Mehault, J -- Michelson, P F -- Mizuno, T -- Moiseev, A A -- Monte, C -- Monzani, M E -- Morselli, A -- Moskalenko, I V -- Murgia, S -- Nakamori, T -- Naumann-Godo, M -- Nestoras, I -- Nolan, P L -- Norris, J P -- Nuss, E -- Ohno, M -- Ohsugi, T -- Okumura, A -- Omodei, N -- Orlando, E -- Ormes, J F -- Ozaki, M -- Paneque, D -- Panetta, J H -- Parent, D -- Pelassa, V -- Pepe, M -- Pesce-Rollins, M -- Piron, F -- Porter, T A -- Raino, S -- Rando, R -- Ray, P S -- Razzano, M -- Razzaque, S -- Rea, N -- Reimer, A -- Reimer, O -- Reposeur, T -- Ripken, J -- Ritz, S -- Romani, R W -- Roth, M -- Sadrozinski, H F-W -- Sander, A -- Parkinson, P M Saz -- Scargle, J D -- Schinzel, F K -- Sgro, C -- Shaw, M S -- Siskind, E J -- Smith, D A -- Smith, P D -- Sokolovsky, K V -- Spandre, G -- Spinelli, P -- Stawarz, L -- Strickman, M S -- Suson, D J -- Takahashi, H -- Takahashi, T -- Tanaka, T -- Tanaka, Y -- Thayer, J B -- Thayer, J G -- Thompson, D J -- Tibaldo, L -- Torres, D F -- Tosti, G -- Tramacere, A -- Uchiyama, Y -- Usher, T L -- Vandenbroucke, J -- Vasileiou, V -- Vilchez, N -- Vitale, V -- Waite, A P -- Wallace, E -- Wang, P -- Winer, B L -- Wolff, M T -- Wood, K S -- Yang, Z -- Ylinen, T -- Ziegler, M -- Maehara, H -- Nishiyama, K -- Kabashima, F -- Bach, U -- Bower, G C -- Falcone, A -- Forster, J R -- Henden, A -- Kawabata, K S -- Koubsky, P -- Mukai, K -- Nelson, T -- Oates, S R -- Sakimoto, K -- Sasada, M -- Shenavrin, V I -- Shore, S N -- Skinner, G K -- Sokoloski, J -- Stroh, M -- Tatarnikov, A M -- Uemura, M -- Wahlgren, G M -- Yamanaka, M -- New York, N.Y. -- Science. 2010 Aug 13;329(5993):817-21. doi: 10.1126/science.1192537.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Space Science Division, Naval Research Laboratory, Washington, DC 20375, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20705855" target="_blank"〉PubMed〈/a〉

Description: A young and energetic pulsar powers the well-known Crab Nebula. Here, we describe two separate gamma-ray (photon energy greater than 100 mega-electron volts) flares from this source detected by the Large Area Telescope on board the Fermi Gamma-ray Space Telescope. The first flare occurred in February 2009 and lasted approximately 16 days. The second flare was detected in September 2010 and lasted approximately 4 days. During these outbursts, the gamma-ray flux from the nebula increased by factors of four and six, respectively. The brevity of the flares implies that the gamma rays were emitted via synchrotron radiation from peta-electron-volt (10(15) electron volts) electrons in a region smaller than 1.4 x 10(-2) parsecs. These are the highest-energy particles that can be associated with a discrete astronomical source, and they pose challenges to particle acceleration theory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abdo, A A -- Ackermann, M -- Ajello, M -- Allafort, A -- Baldini, L -- Ballet, J -- Barbiellini, G -- Bastieri, D -- Bechtol, K -- Bellazzini, R -- Berenji, B -- Blandford, R D -- Bloom, E D -- Bonamente, E -- Borgland, A W -- Bouvier, A -- Brandt, T J -- Bregeon, J -- Brez, A -- Brigida, M -- Bruel, P -- Buehler, R -- Buson, S -- Caliandro, G A -- Cameron, R A -- Cannon, A -- Caraveo, P A -- Casandjian, J M -- Celik, O -- Charles, E -- Chekhtman, A -- Cheung, C C -- Chiang, J -- Ciprini, S -- Claus, R -- Cohen-Tanugi, J -- Costamante, L -- Cutini, S -- D'Ammando, F -- Dermer, C D -- de Angelis, A -- de Luca, A -- de Palma, F -- Digel, S W -- do Couto e Silva, E -- Drell, P S -- Drlica-Wagner, A -- Dubois, R -- Dumora, D -- Favuzzi, C -- Fegan, S J -- Ferrara, E C -- Focke, W B -- Fortin, P -- Frailis, M -- Fukazawa, Y -- Funk, S -- Fusco, P -- Gargano, F -- Gasparrini, D -- Gehrels, N -- Germani, S -- Giglietto, N -- Giordano, F -- Giroletti, M -- Glanzman, T -- Godfrey, G -- Grenier, I A -- Grondin, M-H -- Grove, J E -- Guiriec, S -- Hadasch, D -- Hanabata, Y -- Harding, A K -- Hayashi, K -- Hayashida, M -- Hays, E -- Horan, D -- Itoh, R -- Johannesson, G -- Johnson, A S -- Johnson, T J -- Khangulyan, D -- Kamae, T -- Katagiri, H -- Kataoka, J -- Kerr, M -- Knodlseder, J -- Kuss, M -- Lande, J -- Latronico, L -- Lee, S-H -- Lemoine-Goumard, M -- Longo, F -- Loparco, F -- Lubrano, P -- Madejski, G M -- Makeev, A -- Marelli, M -- Mazziotta, M N -- McEnery, J E -- Michelson, P F -- Mitthumsiri, W -- Mizuno, T -- Moiseev, A A -- Monte, C -- Monzani, M E -- Morselli, A -- Moskalenko, I V -- Murgia, S -- Nakamori, T -- Naumann-Godo, M -- Nolan, P L -- Norris, J P -- Nuss, E -- Ohsugi, T -- Okumura, A -- Omodei, N -- Ormes, J F -- Ozaki, M -- Paneque, D -- Parent, D -- Pelassa, V -- Pepe, M -- Pesce-Rollins, M -- Pierbattista, M -- Piron, F -- Porter, T A -- Raino, S -- Rando, R -- Ray, P S -- Razzano, M -- Reimer, A -- Reimer, O -- Reposeur, T -- Ritz, S -- Romani, R W -- Sadrozinski, H F-W -- Sanchez, D -- Saz Parkinson, P M -- Scargle, J D -- Schalk, T L -- Sgro, C -- Siskind, E J -- Smith, P D -- Spandre, G -- Spinelli, P -- Strickman, M S -- Suson, D J -- Takahashi, H -- Takahashi, T -- Tanaka, T -- Thayer, J B -- Thompson, D J -- Tibaldo, L -- Torres, D F -- Tosti, G -- Tramacere, A -- Troja, E -- Uchiyama, Y -- Vandenbroucke, J -- Vasileiou, V -- Vianello, G -- Vitale, V -- Wang, P -- Wood, K S -- Yang, Z -- Ziegler, M -- New York, N.Y. -- Science. 2011 Feb 11;331(6018):739-42. doi: 10.1126/science.1199705.

Description: Supermassive black holes with masses of millions to billions of solar masses are commonly found in the centers of galaxies. Astronomers seek to image jet formation using radio interferometry but still suffer from insufficient angular resolution. An alternative method to resolve small structures is to measure the time variability of their emission. Here we report on gamma-ray observations of the radio galaxy IC 310 obtained with the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescopes, revealing variability with doubling time scales faster than 4.8 min. Causality constrains the size of the emission region to be smaller than 20% of the gravitational radius of its central black hole. We suggest that the emission is associated with pulsar-like particle acceleration by the electric field across a magnetospheric gap at the base of the radio jet.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aleksic, J -- Ansoldi, S -- Antonelli, L A -- Antoranz, P -- Babic, A -- Bangale, P -- Barrio, J A -- Becerra Gonzalez, J -- Bednarek, W -- Bernardini, E -- Biasuzzi, B -- Biland, A -- Blanch, O -- Bonnefoy, S -- Bonnoli, G -- Borracci, F -- Bretz, T -- Carmona, E -- Carosi, A -- Colin, P -- Colombo, E -- Contreras, J L -- Cortina, J -- Covino, S -- Da Vela, P -- Dazzi, F -- De Angelis, A -- De Caneva, G -- De Lotto, B -- de Ona Wilhelmi, E -- Delgado Mendez, C -- Dominis Prester, D -- Dorner, D -- Doro, M -- Einecke, S -- Eisenacher, D -- Elsaesser, D -- Fonseca, M V -- Font, L -- Frantzen, K -- Fruck, C -- Galindo, D -- Garcia Lopez, R J -- Garczarczyk, M -- Garrido Terrats, D -- Gaug, M -- Godinovic, N -- Gonzalez Munoz, A -- Gozzini, S R -- Hadasch, D -- Hanabata, Y -- Hayashida, M -- Herrera, J -- Hildebrand, D -- Hose, J -- Hrupec, D -- Idec, W -- Kadenius, V -- Kellermann, H -- Kodani, K -- Konno, Y -- Krause, J -- Kubo, H -- Kushida, J -- La Barbera, A -- Lelas, D -- Lewandowska, N -- Lindfors, E -- Lombardi, S -- Longo, F -- Lopez, M -- Lopez-Coto, R -- Lopez-Oramas, A -- Lorenz, E -- Lozano, I -- Makariev, M -- Mallot, K -- Maneva, G -- Mankuzhiyil, N -- Mannheim, K -- Maraschi, L -- Marcote, B -- Mariotti, M -- Martinez, M -- Mazin, D -- Menzel, U -- Miranda, J M -- Mirzoyan, R -- Moralejo, A -- Munar-Adrover, P -- Nakajima, D -- Niedzwiecki, A -- Nilsson, K -- Nishijima, K -- Noda, K -- Orito, R -- Overkemping, A -- Paiano, S -- Palatiello, M -- Paneque, D -- Paoletti, R -- Paredes, J M -- Paredes-Fortuny, X -- Persic, M -- Poutanen, J -- Prada Moroni, P G -- Prandini, E -- Puljak, I -- Reinthal, R -- Rhode, W -- Ribo, M -- Rico, J -- Rodriguez Garcia, J -- Rugamer, S -- Saito, T -- Saito, K -- Satalecka, K -- Scalzotto, V -- Scapin, V -- Schultz, C -- Schweizer, T -- Shore, S N -- Sillanpaa, A -- Sitarek, J -- Snidaric, I -- Sobczynska, D -- Spanier, F -- Stamatescu, V -- Stamerra, A -- Steinbring, T -- Storz, J -- Strzys, M -- Takalo, L -- Takami, H -- Tavecchio, F -- Temnikov, P -- Terzic, T -- Tescaro, D -- Teshima, M -- Thaele, J -- Tibolla, O -- Torres, D F -- Toyama, T -- Treves, A -- Uellenbeck, M -- Vogler, P -- Zanin, R -- Kadler, M -- Schulz, R -- Ros, E -- Bach, U -- Krauss, F -- Wilms, J -- New York, N.Y. -- Science. 2014 Nov 28;346(6213):1080-4. doi: 10.1126/science.1256183.

Description: Recent observations of supernova remnants (SNRs) hint that they accelerate cosmic rays to energies close to ~10(15) electron volts. However, the nature of the particles that produce the emission remains ambiguous. We report observations of SNR W44 with the Fermi Large Area Telescope at energies between 2 x 10(8) electron volts and 3 x10(11) electron volts. The detection of a source with a morphology corresponding to the SNR shell implies that the emission is produced by particles accelerated there. The gamma-ray spectrum is well modeled with emission from protons and nuclei. Its steepening above approximately 10(9) electron volts provides a probe with which to study how particle acceleration responds to environmental effects such as shock propagation in dense clouds and how accelerated particles are released into interstellar space.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abdo, A A -- Ackermann, M -- Ajello, M -- Baldini, L -- Ballet, J -- Barbiellini, G -- Baring, M G -- Bastieri, D -- Baughman, B M -- Bechtol, K -- Bellazzini, R -- Berenji, B -- Blandford, R D -- Bloom, E D -- Bonamente, E -- Borgland, A W -- Bregeon, J -- Brez, A -- Brigida, M -- Bruel, P -- Burnett, T H -- Buson, S -- Caliandro, G A -- Cameron, R A -- Caraveo, P A -- Casandjian, J M -- Cecchi, C -- Celik, O -- Chekhtman, A -- Cheung, C C -- Chiang, J -- Ciprini, S -- Claus, R -- Cognard, I -- Cohen-Tanugi, J -- Cominsky, L R -- Conrad, J -- Cutini, S -- Dermer, C D -- de Angelis, A -- de Palma, F -- Digel, S W -- do Couto e Silva, E -- Drell, P S -- Dubois, R -- Dumora, D -- Espinoza, C -- Farnier, C -- Favuzzi, C -- Fegan, S J -- Focke, W B -- Fortin, P -- Frailis, M -- Fukazawa, Y -- Funk, S -- Fusco, P -- Gargano, F -- Gasparrini, D -- Gehrels, N -- Germani, S -- Giavitto, G -- Giebels, B -- Giglietto, N -- Giordano, F -- Glanzman, T -- Godfrey, G -- Grenier, I A -- Grondin, M-H -- Grove, J E -- Guillemot, L -- Guiriec, S -- Hanabata, Y -- Harding, A K -- Hayashida, M -- Hays, E -- Hughes, R E -- Jackson, M S -- Johannesson, G -- Johnson, A S -- Johnson, T J -- Johnson, W N -- Kamae, T -- Katagiri, H -- Kataoka, J -- Katsuta, J -- Kawai, N -- Kerr, M -- Knodlseder, J -- Kocian, M L -- Kramer, M -- Kuss, M -- Lande, J -- Latronico, L -- Lemoine-Goumard, M -- Longo, F -- Loparco, F -- Lott, B -- Lovellette, M N -- Lubrano, P -- Lyne, A G -- Madejski, G M -- Makeev, A -- Mazziotta, M N -- McEnery, J E -- Meurer, C -- Michelson, P F -- Mitthumsiri, W -- Mizuno, T -- Monte, C -- Monzani, M E -- Morselli, A -- Moskalenko, I V -- Murgia, S -- Nakamori, T -- Nolan, P L -- Norris, J P -- Noutsos, A -- Nuss, E -- Ohsugi, T -- Omodei, N -- Orlando, E -- Ormes, J F -- Paneque, D -- Parent, D -- Pelassa, V -- Pepe, M -- Pesce-Rollins, M -- Piron, F -- Porter, T A -- Raino, S -- Rando, R -- Razzano, M -- Reimer, A -- Reimer, O -- Reposeur, T -- Rochester, L S -- Rodriguez, A Y -- Romani, R W -- Roth, M -- Ryde, F -- Sadrozinski, H F-W -- Sanchez, D -- Sander, A -- Saz Parkinson, P M -- Scargle, J D -- Sgro, C -- Siskind, E J -- Smith, D A -- Smith, P D -- Spandre, G -- Spinelli, P -- Stappers, B W -- Stecker, F W -- Strickman, M S -- Suson, D J -- Tajima, H -- Takahashi, H -- Takahashi, T -- Tanaka, T -- Thayer, J B -- Thayer, J G -- Theureau, G -- Thompson, D J -- Tibaldo, L -- Tibolla, O -- Torres, D F -- Tosti, G -- Tramacere, A -- Uchiyama, Y -- Usher, T L -- Vasileiou, V -- Venter, C -- Vilchez, N -- Vitale, V -- Waite, A P -- Wang, P -- Winer, B L -- Wood, K S -- Yamazaki, R -- Ylinen, T -- Ziegler, M -- New York, N.Y. -- Science. 2010 Feb 26;327(5969):1103-6. doi: 10.1126/science.1182787.
