0Shares0000Sir Alex Ferguson presented Arsene Wenger with a gift at Old TraffordMANCHESTER, United Kingdom, Apr 30- Arsène Wenger praised Manchester United’s ‘classy’ gesture on Sunday after he was handed a commemorative gift by old rival Alex Ferguson ahead of his final game at Old Trafford as Arsenal boss.Wenger later joked that his generous reception before Arsenal’s 2-1 defeat was because he was no longer considered a “danger”. The veteran coach was taking charge of Arsenal for the final time at the Theatre of Dreams, and for the first time since announcing he will leave the Gunners at the end of the season following 22 years in charge.To mark the occasion, Ferguson presented a vase to the 68-year-old Frenchman before kick-off.Quizzed about the applause he received ahead of the game, Wenger replied: “When you’re not a danger any more, people love you.“I am thankful to Manchester United because they had a nice gesture. It is the first time I get a trophy before a game. It is very classy from them.”Wenger chose an inexperienced side for the game, perhaps with an eye on next week’s crucial Europa League semi-final second leg against Atletico Madrid, his young charges losing out in stoppage time to Marouane Fellaini’s header.Still, the Arsenal boss said that whoever takes over from him at the Emirates will have some great young talent to choose from.“My successor will watch this game and hopefully he will come to a positive conclusion because I think they are the future of Arsenal football club – some, 100 percent.” Wenger said. “We had a very young team and the performance was positive.“The players are destroyed because they gave everything and were caught in the final minute.“There were many question marks if we would be strong enough to fight but the quality was good, the spirit was good, many players stood up. We tired a bit in the last 20 minutes and were a bit more under pressure. It was a negative result and a positive performance.”Meanwhile, Wenger remained non-committal when asked about whether he would face off against United boss Jose Mourinho again next season.“I don’t know, honestly. He will be at Manchester United next year certainly and I don’t know where I will be,” he said.0Shares0000(Visited 1 times, 1 visits today)

Photo: James Connolly / PicSell8Research shows Donegal-made ‘Active Irish Honey’ is just as beneficial as world-famous Manuka Honey.‘Active Irish Honey’ won Best Product Award at this year’s Donegal Taste Festival.Through an Enterprise Ireland Innovation Voucher Scheme, research from Sligo IT proves it has the same activity levels as New Zealand Manuka Honey. Conor Daly, Managing Director of Travellogic, is a beekeeper in his spare time.He says that the potential for the market is huge.“Irish consumers want to buy local products for a variety of reasons, not least because it supports jobs locally. The more local the honey the more effective it is believed to be in preventing the symptoms of allergies. Many hay fever sufferers for instance get great relief from consuming locally produced honey.”Daly from Donegal Town works with businessman Austin Duigan, Raphoe and engineer Carl Diver, Falcarragh. They are developing a production and sales model, and hope to have the honey sold all over Ireland.

The simplest group of multicellular animals, the sponges, is not so simple. “Researchers have long regarded sponges as the most primitive form of animal life,” wrote Helen Pilcher in Nature;1 “At first glance, sponges seem simple. They have no gut, no brain, no obvious front or back, left or right. Adults pump water through a system of canals and cavities to extract food.” That apparent simplicity belies some pretty advanced technologies possessed by these creatures. Pilcher mentions several (emphasis added in all quotes):They contain a diversity of cell types; one species contains “at least 11 specialized cell types arranged in a particular pattern.”They contain collar cells with whip-like tails that create currents in the body to ingest food and excrete waste.They produce sperm and egg cells.They have an epithelial layer that provides protection.They make use of a cellular adhesive, integrin, that works with collagen to provide a tether.They communicate with signals that tell developing embryonic cells where to go. “Like more complex animals,” Pilcher writes, “sponges solve this problem by using specific molecules to guide differentiation and migration as the cells develop in their embryos.”These and other characteristics of sponges suggest to evolutionary biologists that the genetic toolkit for these functions was already present in a putative unicellular ancestor before the first metazoan emerged. It seems that the unknown ancestor must have already been “a sophisticated creature.” Later, in Science,2 more marvels about the sponge called Venus Flower Basket were revealed (see 03/01/2004 entry). Not only does it know how to create high-performance, flexible fiber optic cable at low temperatures; now, says MSNBC News, it is able to “build glass cages that have biologists and materials scientists oohing, ahhing and taking notes for future bio-inspired engineering projects and materials.” Reporter Daniel B. Kane continues, “These glass cages have at least seven levels of structural organization, many of which follow basic principles of mechanical engineering,” referring to the paper by Aizenberg et al. who wrote in the abstract, “The ensuing design overcomes the brittleness of its constituent material, glass, and shows outstanding mechanical rigidity and stability. The mechanical benefits of each of seven identified hierarchical levels and their comparison with common mechanical engineering strategies are discussed.” Their opening paragraph puts this discovery in context:Nature fascinates scientists and engineers with numerous examples of exceptionally strong building materials. These materials often show complex hierarchical organization from the nanometer to the macroscopic scale. Every structural level contributes to the mechanical stability and toughness of the resulting design. For instance, the subtle interplay between the lattice structure, fibril structure, and cellulose is responsible for the remarkable properties of wood. In particular, it consists of parallel hollow tubes, the wood cells, which are reinforced by nanometer-thick cellulose fibrils wound helically around the cell to adjust the material as needed. Deformation occurs by shearing of a matrix rich in hemicelluloses and lignin, “gluing” neighboring fibrils, and allowing a stick-slip movement of the fibrils. Wood is an example that shows the wide range of mechanical performance achievable by constructing with fibers. Bone is another example of a hierarchically assembled fibrous material. Its strength critically depends on the interplay between different structural levels—from the molecular/nanoscale interaction between crystallites of calcium phosphate and an organic framework, through the micrometer-scale assembly of collagen fibrils, to the millimeter-level organization of lamellar bone. Whereas wood is fully organic material, bone is a composite, with about half organic and half mineral components tightly interconnected at the nanoscale. However, nature has also evolved almost pure mineral structures, which—despite the inherent brittleness of most minerals—are tough enough to serve as protection for the organism. In mollusk nacre, for example, the toughening effect is due to well-defined nanolayers of organics at the interfaces between microtablets of calcium carbonate. In such structures, the stiff components (usually mineral) absorb the bulk of the externally applied loads. The organic layers, in turn, provide toughness, prevent the spread of the cracks into the interior of the structure, and even confer a remarkable capacity for recovery after deformation.From here, they discuss how the Venus Flower Basket builds its glass house from the bottom up with each level of organization contributing to the high performance of the end product. Their concluding paragraph seems to contain mixed metaphors: design and evolution—The structural complexity of the glass skeleton in the sponge Euplectella sp. is an example of nature’s ability to improve inherently poor building materials [e.g., glass]. The exceptional mechanical stability of the skeleton arises from the successive hierarchical assembly of the constituent glass from the nanometer to the macroscopic scale. The resultant structure might be regarded as a textbook example in mechanical engineering, because the seven hierarchical levels in the sponge skeleton represent major fundamental construction strategies such as laminated structures, fiber-reinforced composites, bundled beams, and diagonally reinforced square-grid cells, to name a few. We conclude that the Euplectella sp. skeletal system is designed to provide structural stability at minimum cost, a common theme in biological systems where critical resources are often limited. We believe that the study of the structural complexity of unique biological materials and the underlying mechanisms of their synthesis will help us understand how organisms evolved their sophisticated structures for survival and adaptation and ultimately will offer new materials concepts and design solutions.In the same issue of Science,3 John Currey provided details on six of the levels of organization investigated by Aizenberg et al.:Euplectella is a deepwater sponge whose glassy skeleton is a hollow cylinder. On the first level of structural hierarchy, nanometer-sized particles of silica are arranged around an organic axial filament. On the second level, alternating layers of silica and organic material form spicules. On the third level, these small spicules are bundled together to form larger spicules. On the fourth level, the larger spicules are arranged in a grid, with struts in longitudinal, circumferential, and diagonal directions, resisting all load modes (see the figure). In the mature animal, these larger spicules are coated with a cementing layer of silica. On the fifth level, this grid is wrapped into a curved cylinder. Finally, on the sixth level, helical surface ridges further resist torsion and stiffen the structure. Currey was most intrigued with level four, a “most remarkable feature” with its cross-beams and struts providing load strength and protection from shear. The MSNBC article contains three photos illustrating the architecture in this “primitive” metazoan. Aizenberg told the reporter, “It puzzles me. In my wildest dreams I can’t imagine how these fibers are assembled to make the nearly perfect, highly regular square cells, diagonal supports and surface ridges of the cage.” Despite the simplicity of the sponge’s anatomy, possessing no brain or nervous system, these structures represent “some of the most complex and diverse skeletal systems known.”1Helen Pilcher, “Back to our roots,” Nature 435, 1022-1023 (23 June 2005) | doi: 10.1038/4351022a.2Aizenberg et al., “Skeleton of Euplectella sp.: Structural Hierarchy from the Nanoscale to the Macroscale,” Science, Vol 309, Issue 5732, 275-278 , 8 July 2005, [DOI: 10.1126/science.1112255]3John D. Currey, “Materials Science: Hierarchies in Biomineral Structures,” Science, Vol 309, Issue 5732, 253-254 , 8 July 2005, [DOI: 10.1126/science.1113954].Wild dreams and imagination are not science; they indicate that Aizenberg is in a philosophical slumber by attributing engineering to evolution. If evolution produced this sponge’s architecture, as assumed by faith by these investigators, each stage must have contributed to an end result. Stage four would not help unless the lower stages in the hierarchy were already conferring their benefits; it would be like trying to build struts out of crumbly styrofoam or bits of broken glass. But end results are prohibited by evolutionary theory which stresses that evolving organisms have no goal in mind. In the Nature article, Simon Conway Morris extolled Tinker Bell: “Evolution is an extremely dynamic system and paradoxically a very lazy one. It will co-opt whatever it can.” Evolutionists preach that laziness and tinkering with available parts produced wonders of engineering that are the envy of materials science. It’s time to replace Darwin’s tomb in Westminster Abbey with Kepler’s, and change the objective of science from explaining away God back to thinking God’s thoughts after Him. This will lead to productive inquiry in science. Notice that the researchers here were oohing and ahhing not over Charlie’s little outworn myth, but over the engineering design apparent in the lowly sponge.(Visited 30 times, 1 visits today)FacebookTwitterPinterestSave分享0

In part two, Dr. Cheatham discusses bilingualism and assessment and gives his tips on working with dual language families.You can find a transcript of this video here.
This, in all its molecular complexity, is what the bulging end of a single neuron looks like. A whopping 300,000 proteins come together to form the structure, which is less than a micrometer wide, hundreds of times smaller than a grain of sand. This particular synapse is from a rat brain. It’s where chemical signals called neurotransmitters are released into the space between neurons to pass messages from cell to cell. To create a 3D molecular model of the structure, researchers first isolated the synapses of rat neurons and turned to classic biochemistry to identify and quantify the molecules present at every stage of the neurotransmitter release cycle. Then, they used microscopy to pinpoint the location of each protein. Some proteins—like the red patches of SNAP25 visible in the video at 0:14—aid in the release of vesicles, tiny spheres full of neurotransmitters. Others—like the green, purple, and red rods at 0:45—help the synapse maintain its overall structure. Different proteins surround vesicles when they’re inside the synapse—the circles scattered throughout the structure at 0:56—than when the vesicles are forming at the edge of the synapse—as shown at 2:08. Researchers can use the model, described online today in Science, to better understand how neurons function and what goes wrong in brain disorders.(Video credit: Wilhelm et al. 2014, Science)*See related Report: Composition of isolated synaptic boutons reveals the amounts of vesicle trafficking proteinsSign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)

From Lalit K Jha Washington, Feb 17 (PTI) The US will continue to fly, sail and operate wherever international law allows and will support the right of all nations to do the same, President Barack Obama has said as he sought “tangible steps” to lower tensions in the South China Sea amid flexing of muscles by China. “We discussed the need for tangible steps in the South China Sea to lower tensions, including a halt to further reclamation, new construction and militarisation of disputed areas,” Obama told reporters yesterday at the end of the first US-ASEAN Summit in Sunnylands, California. “We will continue to help our allies and partners strengthen their maritime capabilities, and we discussed how any disputes between claimants in the region must be resolved peacefully, through legal means, such as the upcoming arbitration ruling under the UN Convention of the Law of the Seas, which the parties are obligated to respect and abide by,” Obama said. “Mutual respect for the sovereignty, territorial integrity, equality and political independence of all nations by firmly upholding the principles and purposes of the Charter of the United Nations, the ASEAN Charter and international law,” Obama and ten ASEAN leaders said in a joint statement. “Freedom of navigation must be upheld, and lawful commerce should not be impeded. I reiterated that the United States will continue to fly, sail and operate wherever international law allows and we will support the right of all countries to do the same,” Obama said.He said one of his main messages over the past two days has been the commitment of the US to ASEAN and its people.advertisementThat commitment is and will remain strong and enduring, he added.”With our strategic partnership, we have a framework to guide our ties for decades to come. Here at Sunnylands, we agreed to a number of key principles, including the principle that ASEAN will continue to be central, in fact indispensable, to peace, prosperity and progress in the Asia Pacific,” Obama said.”When ASEAN speaks with a clear, unified voice, it can help advance security, opportunity, and human dignity, not only for the more than 600 million people across ASEAN, but for people across the Asia Pacific and around the world. And Im pleased that here at this summit, ASEANs strong voice allowed us to make progress on multiple fronts,” Obama said.China says it has a historical right to all of the South China Sea.Taiwan and ASEAN members Brunei, Malaysia, Vietnam and the Philippines also claim land features in these potentially resource-rich international shipping lanes.
