(Visited 39 times, 1 visits today)FacebookTwitterPinterestSave分享0 Another “feathered dinosaur” story has caused a flap and flurry of news reports. But are they really feathers, and do they help evolutionary theory?An exceptionally preserved juvenile in typical “dinosaur death pose” was unearthed in German limestone and given the name Sciurumimus (“squirrel-mimic”). Labelled Jurassic by the researchers who announced the discovery in PNAS,1 this is the first non-coelurosaur species described with integumentary structures. It is leading some to postulate that all the branches of dinosaurs had “feathers,” as stated in National Geographic‘s article: “‘Probably all dinosaurs were feathered,’ scientist concludes.”One will look in vain, though, for veined feathers with barbs and barbules as found in birds. The authors label the structures “type 1 feathers,” meaning single filaments protruding from the skin (see 9/15/2011 entry). They are actually little more than fuzz, barely noticeable in the photos. Co-author Helmut Tischlinger said, “Under ultraviolet light, remains of the skin and feathers show up as luminous patches around the skeleton.” Some, like Brian Switek at Nature News, dub them “protofeathers.” He wrote,Palaeontologist Paul Barrett of London’s Natural History Museum agrees that the structures on Sciurumimus are probably protofeathers. Although additional geochemical work is needed to study the features’ details, Barrett says, the fossilized wisps are very similar to the fuzz seen on other dinosaurs. But he notes that the presence of these filaments among all dinosaurs is “speculation”. Feathery structures might be a common feature of dinosaurs, but it’s also possible that they evolved multiple times. “We need more examples in both non-coelurosaurian theropods, and particularly in the other big dinosaur groups, before we can really speculate that these features are a character of dinosaurs as a whole,” Barrett says.Reporters seem unsure what to make of the news. Co-author Mark Norell said, according to Science Daily, “This is a surprising find,” noting that it appeared in the same limestone in northern Bavaria as Archaeopteryx (discovered 150 years ago), that was fully fledged with flight feathers: meaning, at the very least, that this creature and birds with powered flight were contemporaries. Clearly whatever the fuzz was on this creature, it had nothing to do with flight. Though the juvenile in the fossil was only 28″ long, “Adult megalosaurs reached about 20 feet in length and often weighed more than a ton,” Science Daily reported. “They were active predators, which probably also hunted other large dinosaurs.” Not even believers in dinosaur-to-bird evolution think this creature was closely related to birds.Of note is that this fossil came from a private collector and looks, at first glance, almost too good to be true. Assuming it is authentic and trustworthy, though, paleontologists have their work cut out for them. “Although the feathers look similar among different dinosaur groups, it’s still possible the trait evolved independently, without a common ancestor,” National Geographic suggested (look for phrase “repeated evolution” in the 7/01/2012 entry). Everyone seems to agree there’s not enough information to make sweeping conclusions. NG reporter Christine Dell’Amore quoted Corwin Sullivan saying, “We paleontologists are going to need to find more fossils—of things even less closely related to birds than Sciurumimus—to be sure.”Moreover, the discovery “upends [the] feather theory,” National Geographic headlined, and also upends the portrayal of dinosaurs as “overgrown lizards.” Switek remarked, “If so, we will have to start thinking about what kind of feathery covering these creatures display when we depict them in art and film.”1. Rauhut, Foth, Tischlinger and Norell, “Exceptionally preserved juvenile megalosauroid theropod dinosaur with filamentous integument from the Late Jurassic of Germany,” PNAS, published online July 2, 2012, doi: 10.1073/pnas.1203238109.You have type 1 protofeathers, too. They’re called hairs. Imagine finding a fossil skeleton of a horse so well preserved, impressions of its mane and tail were clearly seen in the rock (but strangely, none of the internal organs). Would you be justified in saying that horses were evolving flight? Horsefeathers. Would it make any sense to say that the trait originated further back than expected, implying that the common ancestor of birds and Pegasus had protofeathers? If you didn’t already “know” the evolutionary story about how mammals, dinosaurs and birds are supposed to have evolved, it would be a similar inferential fallacy.There’s still something very weird about these “feathered dinosaur” discoveries. They are found in Germany or China, often involve the same fossil-hunters, and often come from private collectors.Even giving the evolutionists the maximum credibility about the authenticity of the fossils, they still usually create problems for Darwin. They don’t show a clear path from fuzz to flight. The “protofeathers” are on the wrong animals. They have an unknown function. Their dates overlap, or belong in the wrong eras. They don’t show a progression in complexity over time till true powered flight is thought to have evolved. They are either simple protrusions, or complex feathers found on animals that clearly used them for flying or gliding (or perhaps were secondarily flightless, see 5/01/2010). Given how quickly animals equipped for flight could conquer the globe, one would expect to find them everywhere (compare pterosaurs, flying insects, bats). Informed skepticism is still in order.Another lesson is how readers can be distracted by the wrong questions. Stop listening to the evolution tales, and ask other questions: Why are dinosaurs so often found in the typical death pose, suggesting rapid suffocation in water (11/23/2011)? Why are they exquisitely preserved? Why do so few reporters fail to question the dates and stories of the Darwinists? Why don’t they focus, instead, on the high levels of complexity required to have an animal run, hunt, fly, or live at all?Exercise: Based on observations of the fossils alone, undistracted by evolutionary assumptions, list other questions the evolutionists and their lackey reporters never ask.

To prevent their hives from being attacked by invaders, wasps must quickly distinguish friend from foe. They typically do this by sniffing out foreigners, as outsiders tend to have a different scent than the home colony. Now researchers have discovered that, like a few other wasp species, a tiny social wasp (Liostenogaster flavolineata) from Malaysia employs an additional security measure: facial recognition. The wasps’ nests are typically found in large aggregations with as many as 150 built close together, and each colony faces persistent landing attempts by outsiders from these other nests. To find out why and how these wasps employ both vision and scent to determine if an incoming wasp is a comrade, scientists carried out a series of experiments on 50 colonies (see photo above) in the wild. Close to the nests, the researchers dangled lures made of captured and killed wasps. The lures had been given different treatments. For instance, some lures made from nest mates were coated with a foe’s scent, whereas outsiders were painted with the colony’s odor. The wasps, it turns out, pay more attention to facial markings than to scent when faced with a possible intruder, the team reports online today in the Proceedings of the Royal Society B. Indeed, in tests where the wasps could assess both an intruder’s face and scent, they relied solely on facial recognition and immediately attacked those whose faces they didn’t know, ignoring their odor. That’s the safest strategy, the scientists note, because the wasps can recognize another’s face at a distance, but need to actually touch another wasp to detect her scent—not a bad ploy for a tiny-brained insect.(Linked photo credit: David Baracchi)Sign 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(*)
EAST RUTHERFORD, N.J. (AP) — Defensive tackle Markus Kuhn (knee) and linebacker James Morris (quad) were placed on injured reserve by the New York Giants on Friday.The Giants signed two players from their practice squad, defensive end Brad Bars and tight end Matt LaCosse.Kuhn, a fourth-year pro, injured his knee on Dec. 14 in a victory at Miami.

What are the skill sets required for the Indian youth to be employable? Exposure to life-experiences, career options and education streams at a very early stage of life plays a much important role in anyone’s professional life.advertisement India Today Web Desk New DelhiJuly 1, 2019UPDATED: July 2, 2019 15:33 IST What are the skill sets required for the youth in country to be employable?Skill sets are always looked at as a means to progress and succeed in anyone’s professional life; however, what is often under looked is the importance of overall-exposure in life. Exposure to life-experiences, career options and education streams at a very early stage of life plays a much important role in anyone’s professional life. Youth of this generation is often heard saying that the competition is much tougher nowadays. What are the skill sets required for the youth in country to be employable?On the other hand they need to be mindful that exposure also is much better now, with increased internet penetration and various educational apps, online courses available on something as accessible as a smartphone. Exposure comes in many ways i.e. our schooling, socio-economic environment, Hobbies like reading, traveling, sports, arts etc. Each of these adds to perceptiveness of a person.These factors decide our approach towards a professional life very early on. Skill sets are obviously very important but youths and their parents should also try to increase the life-experience exposure as much as possible; this makes them smarter, resourceful and independent to make smart choices.The necessary skill sets come after competencies and the ones that should be focused on are:Soft skills and over-all grooming i.e. communication, body-language, inter-personal skills, dressing-style etc. makes you a pleasant person to come-by.General Aptitude i.e. language, mathematics, reasoning, reading comprehension forms the base of all other skills that can be acquired at any stage of someone’s career.General awareness makes you an informed person who can conduct his basic duties and be aware of rights in a society; general awareness makes you perceptive of how you should conduct yourself in a society.In the end comes the skill sets and is just the tip of the iceberg. Skill sets at any stage in our professional life has to cascade out of current developments in our commercial/economic environment.advertisementFor example, the current trending buzzwords in India are data, energy, environment-conservation, security and safety, infrastructural growth, start-ups, electric vehicles, politics, investments, taxation regime. All these buzzwords have a full gamut of career-options surrounding them. If we pick any two of these, suppose “data” and “electric vehicles”, we see that there are companies looking for data science specialists that can help them build self-driven electric vehicles. What are the skill sets required for the youth in country to be employable?Now this would be an ideal place for a science student with background of mechanical engineering and data science where the data science is a skill set acquired most likely at a later stage or with the engineering education. There are many permutation and combination of these buzzwords and career options emanating out of them. What matters is overall exposure and the competencies to be cognizant of the career-opportunities and then developing suitable skill sets for a chosen area.CBSE has done a great job of compiling education+career options list, once a student decides a choice, skill sets are the tools they will be able to find with the help of area experts.Authored article by Gaurav Chauhan, Senior Research Fellow, Great Lakes Institute of Management, GurgaonRead more: Here’s how Ed-tech companies are helping aspirants to boost their career in a better wayGet real-time alerts and all the news on your phone with the all-new India Today app. Download from Post your comment Do You Like This Story?

zoom ACO Marine, part of German ACO Group, has unveiled a new Clarimar MF wastewater management system for yachts operating with no more than 12 passengers.Using the same technology applied to the larger models used in the commercial, offshore and military sectors, the new Clarimar MF (LY3) is designed specifically to meet the requirements of yachts built to comply with the Large Commercial Yacht (LY3) Code, the company said.The LY3 Code applies to yachts which are 24m and over in load line length, are in commercial use for sport or pleasure, but do not carry cargo or more than 12 passengers.“Many technologies currently in use on these yachts typically depend on dilution and chemical sterilisation to achieve effluent standards. The introduction of the biological-type Clarimar MF (LY3) means all segments of the global yacht sector now have access to a more effective and reliable wastewater treatment process,” Mark Beavis, ACO Marine Managing Director, said.As explained, the system applies to yachts where compliance with Section 4.2 of the revised IMO MEPC 227 (64) rules relating to nitrogen and phosphorous removal is not required.“A biological treatment system is fast becoming the industry standard for the 50m plus yacht and recognised as a viable and practical alternative to physical/chemical and dilution technologies,” Beavis added.
More Nova Scotians have access to a regular family doctor thanany other Canadians, according to the latest health report fromStatistics Canada. The 2003 Canadian Community Health Survey (CCHS) found that 94.9per cent of Nova Scotians have a regular family doctor, wellabove the national average of 85.8 per cent. “Access to a family doctor and other primary health-careproviders makes a big difference to the well-being of many NovaScotians,” said Health Minister Angus MacIsaac. “That’s why,through Nova Scotia’s plan for better health care — Your HealthMatters — we have been working so hard with our communitypartners to attract new doctors and keep them in the province. Although there is certainly more to be done, we’re seeing somepositive results.” Recruiting doctors requires a collaborative and continuous effortby district health authorities, communities, local doctors andthe provincial physician recruitment office. Already, in 2004,about 16 new family doctors have come to various communities inthe province. A five-year incentive program is offered in 21 rural communities.The program provides an annual bonus for each completed year ofservice, moving expenses, continuing medical education fundingand guaranteed minimum billing (income) for the year. At present,28 of the 34 positions are filled. Other provincial programs include: start-up contracts for familydoctors, alternative funding payment plans, a debt assistanceprogram, and a physician recruitment office that maintains arecruitment website and co-ordinates site visits, advertising,and CV distribution within the province. The move to develop more opportunities for community-basedservices (Primary Health Care) includes building multi-professional care teams. These teams will help improve access tohealth services for residents and improve the quality of worklife for health professionals. Nurse practitioners, who workjointly with family doctors, are one example of this PrimaryHealth Care system at work. There are currently 13 nursepractitioner positions in Nova Scotia. Although the statistics released this week are positive for NovaScotia, there are still thousands of residents who do not have afamily doctor. To help people find a doctor, the Department of Health offers aprovincial directory of doctors who are taking new patients. This is available to Nova Scotians via the Internet on thewebsite at www.gov.ns.ca/health/physicians/physicians.asp and via a telephone information line (902-424-3047). Ongoing recruitment efforts are also targeted at specialists,both for urban and rural areas. In the past few months, about 15new specialists have been recruited including doctorsspecializing in obstetrics and psychiatry in Southwest Nova andin anesthesiology and general surgery in Cumberland County. To help meet future demands, doctors across Nova Scotia are beingconsulted on a physician resource plan to ensure that Nova Scotiahas the right number of family doctors and specialists working inthe right places, now and in the future. Having an appropriate number of family doctors and specialistsacross the province is critical for a stable health-care system.
CALGARY – A police officer has told a Calgary court that a man three of his colleagues are accused of roughing up last summer did not appear to be combative.Constables James Othen, Kevin Humfrey and Michael Sandalack have all pleaded not guilty to assault causing bodily harm.They are accused of beating up Clayton Prince after the car he was driving was pulled over on July 30, 2016.Const. D’Arcy Oakes, who says he watched events unfold from nearby, testified that he heard Prince being yelled at to stop resisting arrest and to put up his hands.Oakes described seeing the officers hit Prince with their knees and fists while he was on the ground, and said Prince had a bloodied nose and mouth when they led him to a police vehicle.Oakes told court that it did not appear that Prince was resisting arrest and that the officers should not have had any trouble handcuffing him.During cross-examination, defence lawyers questioned Oakes’s recollection of what happened.Humfrey’s lawyer, David Butcher, said notes Oakes wrote that night don’t mention the use of force.“The purpose of your notes is that you can accurately remember what happened when you are required to give evidence about the event, often month or years later,” Butcher said, to which Oakes responded “correct.”Butcher asked whether Oakes had failed to follow the Calgary Police Service’s note-taking policy and whether his notes from that night are now unhelpful. The officer again replied that the defence lawyer was correct.Prince was chased by police after he ran away from a traffic stop. Charges of resisting arrest and possession of marijuana were later stayed.A provincial body that probes serious police actions began investigating a month after the arrest when video from a police dashboard camera contradicted officer accounts.The Alberta Serious Incident Response Team said Prince sustained broken ribs, a collapsed lung, a facial laceration and significant bruising.Othen and Humfrey also face charges of public mischief for allegedly making false statements.Othen faces an additional charge of assault with a weapon — a key he is accused of digging into Prince’s neck.
SYDNEY, N.S. – The mayor of Nova Scotia’s second largest municipality has come out as gay, saying he decided to speak publicly after someone threatened to expose his personal life.Cecil Clarke, mayor of the Cape Breton Regional Municipality and a likely leadership candidate for the province’s Progressive Conservatives, spoke out about his private life in an interview with CBC on Thursday.The 49-year-old politician said he didn’t want to run for the Tory leadership with people thinking they could shame him or hold something over him.“I’m not going to go forward and announce my intentions about the Progressive Conservative party leadership race having people think that they’re going to shame me … that being gay is somehow a bad thing,” he told CBC Sydney’s Mainstreet.“Who I am and how I go about my personal life is no longer up as a punching bag for me politically.”Clarke said he’s in a committed relationship with someone he loves and who supported his decision to speak publicly.“That man is very special to me and I’m not prepared to go on my future journey alone,” he said. “I’m not going to do it ashamed or afraid or not proud of who I am as a person. And I hope, I hope people will not allow that to cloud who I am as a politician either.”Still, he described the threats against him as prompting “a very dark time” that brought him to a low point.“When I was four and then seven, I was sexually assaulted as a child and I thought I recovered very well from that,” Clarke said. “I had the love of a family that was there for me and a community that supported me. And this week, all of that hurt and pain came barrelling back and I said ‘You don’t own this, you don’t own me.’”He added: “I owe it to myself to be true going forward because I’m not going to have people trying to shame me.”The Sydney Mines native served in the provincial legislature as a PC MLA for a decade before returning to Cape Breton to become mayor in 2012.Clarke is expected to announce whether he will run for the PC leadership Saturday in North Sydney.Christina Lamey, a spokeswoman for the municipality, said the mayor decided to speak out after an incident earlier this week.At issue was “hateful speech” directed at Clarke’s sexuality, she said.“He’s been in political life most of his adult life. He’s very focused on his work and dedicated to his job and kept his private life private,” Lamey said. “But those comments were unacceptable and rather than allow someone to shame him, he decided enough was enough.”Clarke received an outpouring of support of social media, with many applauding his courage to come forward and tell his story and condemning the homophobia and threats he endured.“There’s no place in our PC party for homophobia or discrimination,” MLA for Pictou East and PC leadership candidate Tim Houston said in a tweet. “Mr. Clarke’s private life should not be up for attack. Period.”Rob Batherson, a former PC party president, said on Twitter that Clarke “showed tremendous courage” and that there is “no place for hate or homophobia.”Two years ago, another Cape Breton Island politician said someone had tried to blackmail him into resigning by threatening to reveal a call made from his hotel room to a male escort service.Steve Sampson, a member of Richmond County council, said at the time he received an unmarked envelope in the mail in 2016 at his home containing a photocopy of a hotel bill from 2014, incurred while on county business in Seattle, Wash.
