More imaginary feathers on a dinosaur have been discovered. A BBC News article shows a cartoon of a dinosaur with feathers on its arms. This is strange, because the paper it refers to makes no claim about feathers – only that certain structures had been interpreted as feathers by some. The original paper by Theagarten Lingham-Soliar (U of KwaZulu-Natal, South Africa) described a Psittocosaur from China that is remarkable in one respect: it exhibits dinosaur skin in cross section with the finest detail ever found. Published in the Proceedings B of the Royal Society,1 the paper says that “Also, for the first time in a dinosaur two fibre layers parallel to the skin surface are preserved deep within the dermis at the base of the cross section.” Collagen at least 25 layers deep – maybe 40 layers deep – suggests that the skin of this species was tough and rigid, providing protection for internal organs. Tooth marks from a possible predator attack were also found. For these reasons, the author said this specimen “gives a remarkable, unprecedented understanding of the dinosaur skin.” It should, therefore, provide an ideal case for a feather hunt. The BBC report made overt claims about feathers in addition to its cartoon: “The plant-eating Psittacosaurus had a thick layer of shark-like skin hidden under scales or feathers.” The caption said, “Some scientists believe a number of dinosaurs had feathers.” Another quote hedged a little: “Soft tissues such as skin are rarely preserved in the fossil record, leading to heated debate over what dinosaurs looked like, and whether they were covered in primitive feathers or scales.” What did the original paper say about feathers? Not much. The only relevant statement was, “To date, all integumental structures described in dinosaurs, whether interpreted as ‘protofeathers’ or structural fibres, occur on the surface of the animal or on adjacent substrate.” A look at the references for such interpretations showed two for and two against. The most recent paper in the references was by Feduccia and Wang denying that so-called feathers are anything more than degraded collagen fibers. The only other comment about feathers in the paper was about the uniqueness of bird skin: “A generalization of the primary functional role of the dermis in the protection and/or support for the enclosed body mass may be extended to most vertebrates with the possible exception of birds, wherein the dermis plays a unique role with respect to feather attachments.” Nothing in the paper, therefore, supported the claim that the well-preserved skin of this Psittocosaur had feathers, despite the BBC’s depiction.Update 01/10/2008: The author of the paper denies that these are feathers. Roger Highfield, reporting for the UK Telegraph, found out that the point of Theagarten Lingham-Soliar’s paper was to refute the notion that the collagen dermis layers contain proto-feathers. Here is what he told the Daily Telegraph:Scientists must really now choose – belief in the nebulous idea of protofeathers or the reality of collagen, the dominant protein in vertebrates. I am convinced from the nonsense spouted by many of the people who denounce collagen in favour of protofeathers that they have never actually seen collagen in its natural or decomposing state.”Lingham-Soliar also denies that Sinosauropteryx, a turkey-size dinosaur unearthed in 1994, had feathers. He thinks, instead, that the impressions were remains of collagen that supported a dorsal frill running down the head and back. Highfield ended his article, “Although the new work will not challenge the link between birds and dinosaurs it will lead to a fundamental rethink of why feathers evolved in the first place.”1. Theagarten Lingham-Soliar, “A unique cross section through the skin of the dinosaur Psittacosaurus from China showing a complex fibre architecture,” Proceedings of the Royal Society B, ISSN: 0962-8452 (Paper) 1471-2954 (Online), Issue: FirstCite Early Online Publishing; DOI: 10.1098/rspb.2007.1342.The evolutionary flights of fancy in the news media are irresponsible and detrimental to scientific objectivity. Here was another media flap by the BBC, trying to pull imaginary feathers out of leathery skin, because they so wish for dinosaurs to be the ancestors of birds (compare 06/13/2007). The Telegraph article was more fair, but still clung to the link between dinosaurs and birds as if that belief is too sacrosanct for evidence. The reporters and scientists should have been questioning the 70 million years during which this specimen supposedly lay there, its skin exquisitely preserved down to the collagen fibers for all that time. The carcass of a cow, deer or bird will decay to the bone in months. The conditions under which such “extraordinary preservation” occurred, and a reappraisal of the dating, should be the first item of business.(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0
Sonjica said about 200 special prosecutors had been trained, added that she expected these courts to operate similarly to Labour Courts, in that they would only operate at particular times. Sonjica said the government would also be encouraging reuse of water, which the town of George was already implementing. The seven new projects include the Mokolo augmentation project to supply water to the planned Medupi Power station in Lephalele in Limpopo province, and the Mooi-Mgeni Transfer Scheme project, which would include the construction of the Spring Grove dam around eThekwini/Durban and Umgungundlovu in KwaZulu-Natal. 14 April 2010 Sonjica said that with impending climate change, the country also had to consider other means of securing its water supply. Ruiters said water had been stolen at Mokolo, Berg and Olifants catchment areas, and that 250-million cubic metres of water had been illegally obtained over one year from Vaal. She said the department was busy drafting a policy on desalination, but that the drought along the Western Cape Garden Route had stalled the plan. Source: BuaNews In addition, four special “water courts” would be set up across the country and would run as pilot projects from May in a bid to crack down on those that committed water abuses. The department was using the rehabilitated a unit on the West Coast which had been in use for over 20 years, and was also putting to use a unit in Sedgefield near Knysna in the Western Cape. Nelson Mandela Municipality/Port Elizabeth was also interested in using desalination technology. “The problem is that water has been looked at as an after-affect when we plan for development, and we are trying to change that,” said Sonjica, adding that her department was considering desalination of sea water as a possible option. Desalination, refuse water usage Commenting on illegal water use, the department’s deputy director-general, Cornelius Ruiters, said a full-time unit had been dedicated to compliance and monitoring, and the department was engaging with the Department of Agriculture to combat illegal water use. Pilot water courts Sonjica added that the government had no plans to raise the price of water, while pointing out that South Africa was among a few countries in the world where the tap water was safe to drink. South Africa is shoring up the security of its water supply by ensuring the completion of seven major new water projects around the country by 2014, Water Affairs Minister Buyelwa Sonjica said at a pre-budget briefing in Cape Town this week.
Color’s FutureI started out this post by comparing Color’s user experience to Twitter 5 years ago, which baffled early adopters too. Indeed, Color co-founder Peter Pham recently told The Hollywood Reporter that Color is like a “visual Twitter.” In the end, Color is a unique app and it isn’t precisely like any other – even Twitter. While there were some initial problems with the functionality, I am optimistic about Color’s future. As smartphones and other Internet-connected devices proliferate, it will be apps that augment our real world experiences that will prosper. See also:Color CEO: The Tech Justifies the $41 MillionOnce the early adopters get used to Color – and it will take time to figure out how and where Color works best, just as it did with Twitter – then I expect to see usage filter through to mainstream users at concerts, events, conferences and other large gatherings of people. Whoever is the next Lady Gaga in 5 years time, my bet is that her concerts will generate thousands of photos and videos from Color users. In short, I believe that Color has a very good chance of becoming a large scale success like Twitter. Certainly it’s funded to do so!Do you agree? Let us know your thoughts on Color’s future, or your usage of it now, in the comments.UPDATE: See also the follow up post: How Color is Being Used. It features more examples of Color usage, including from a concert and a BBQ. Top Reasons to Go With Managed WordPress Hosting Tags:#Location#NYT#Series#UX Evolutions#web 8 Best WordPress Hosting Solutions on the Market richard macmanus Color Demo from Color Labs, Inc. on Vimeo.The ideal use case for Color then, is for events with large groups of people – like a concert or conference. Color ostensibly allows you to share your experience with that group; as well as augment your experience by giving you alternate views and allow you to see things that you’d otherwise have missed. ReadWriteWeb’s resident hacker, Tyler Gillies, recently used Color at a tech conference and noted that it allowed him to see slides from many different sessions.Color Goes to the Movies In mid-April, Color set out to showcase its new app at the premiere of a new Hollywood film called “Water for Elephants.” At the event, 49 people took 788 photos using Color – according to the event’s web page. In scanning those photos, they range from official and fan photos of the movie’s stars as they walk down the the red carpet, to photos of fans as they wait for the action to start. If the goal was “to bring the red carpet to fans who could not be in Manhattan,” as HollywoodNews.com claimed, then that didn’t work. While I personally believe that the world can never have enough photos of Reese Witherspoon, it’s doubtful that 788 blurry photos of the red carpet was a compelling experience for people who didn’t attend. The real question is: what value did the people taking those photos get from Color, while the event was happening? I couldn’t find any of that user feedback online and so I’ve asked Color for comment. In the meantime, I asked the ReadWriteWeb community via Twitter if they’ve used Color, and if so was it of value? Here’s a sample of responses, collected via Storify: A Web Developer’s New Best Friend is the AI Wai… Why Tech Companies Need Simpler Terms of Servic… Related Posts Love it or loath it, the smartphone app Color is one of the most innovative Web products to have launched this year. It has a user experience that is as unique and different as Twitter was 5 years ago. This has led to confusion about how to use Color and questions about its value. In this post we look at the early uses of Color and analyze its chances of emulating the success of Twitter.Color launched last month in a whirl of hype, mostly due to the eye-opening $41 million prelaunch funding. But since then, the user experience has been the center of focus. Many people have complained that the app is difficult to understand – mainly because the benefits of the app are only clear once you use it amongst a crowd of people and in real-time. The user interface of the app has also been accused of being confusing and inconsistent. What is Color, Again?Color enables you to share “photos, videos and conversations” with a group of people who are at the same location as you. The idea is that it’s only useful when you’re in the proximity of a group of people. That word, proximity, has since become a trending term among the tech set. Rather than being about your social connection to someone, Color is about how close you are to them. Is this the next wave of mobile apps? Color is hoping so.Here’s a quick intro:

S. KannanFormer India all-rounder Kirti Azad’s campaign against Delhi’s cricket administrators has turned out to be a fruitful one with the government on Thursday ordering an inspection of the “account books” of the Delhi & District Cricket Association (DDCA).Azad, a BJP Member of Parliament, raised a question on September 6, alleging manipulation of financial and other records, improper conduct of AGMs, irregular purchases, injudicious fund spending and payment of honorariums against the provisions of the Articles of Association.In his written reply, the Minister of State for Corporate Affairs, RPN Singh, informed that the inspection of the account books and other records of the DDCA under Section 209 A of the Companies Act of 1956 has been ordered.Narinder Batra, treasurer, DDCA told Mail Today: “We have no objection to the inspection of our accounts by agencies concerned. Our accounts are properly audited and if any authority wants to see it, we have no objection at all.”It is learnt the Serious Fraud Investigation Office (SFIO) is expected to start its investigation next week. It will go through the accounts of the last eight years, when major construction activity was going on at the DDCA.Azad had moved a privilege motion in the Lok Sabha against the false reply submitted by Ministry of Urban Development (MUD), which is at variance with its own RTI replies. It clearly admits that there is no valid lease executed between Ministry of Urban Development and the DDCA.It is learnt that the DDCA has so far spent over Rs 100 crore on construction of the Kotla stadium during this eight-year period. Azad and other DDCA pressure groups have been demanding a probe into the mismanagement of cricket affairs in the Capital.Azad also sat on a day-long dharna along with many other former India players just before the start of season five of the IPL.Subsequently, the one-time payment by the Indian cricket board (BCCI) to Azad and other cricketers was stopped at the DDCA’s behest after the dharna.The payment was released only after three former cricketers – Maninder Singh, Surinder Khanna and Gursharan Singh -under pressure from the DDCA gave written apologies with an assurance that “they didn’t support Kirti Azad against DDCA”.However, Azad says that every single player from Delhi wants the cricket system to be cleaned up. “If confronted with a situation where people have to lose money ranging from Rs 35 to 70 lakh, only lion hearted or financially secure individuals will take a stand. Sadly, DDCA used pressure tactics to get these players to retract their stand. But be assured that all cricketers are with us in the battle against DDCA’s mismanagement and corrupt practices,” said the 1983 World Cup-winning team member.”This will be ‘Kotla Gate’. All the years of mismanagement of funds will be exposed. The personal worth of top DDCA officials has grown manifold in the period under review. Elections have become a farce with just four or five senior DDCA executive members registering and casting 700 to 2000 proxies each – collection of these proxies in 14 days is physically impossible for any one individual,” said Azad on Saturday.Asked if this means fighting fellow partyman and Leader of the Opposition in the Rajya Sabha, Arun Jaitley, Azad said: “It has nothing to do with the party because the party itself has nothing to do with cricket. I have all regard for Mr Jaitley.”Former players, though, have welcomed the inquiry. “We were forced by the DDCA to give apologies. But we are one on the issue of cleansing cricket in Delhi,” two of the three players said.advertisement

Guest poster Derek Duke is back for his second week of Big 12 power rankings.Another college football Saturday has come and gone yet again. After all the excitement that happened this past weekend, you’re probably a little bit bummed to be back at work this week. No worries my friend, I have exactly what you need to cure your Monday blues. From 10 to one, I have a Big 12 power ranking to get your week off on the right track.10. Kansas (1-9, 0-7) Trend: DownAfter yet another loss, this Jayhawk team is still winless in conference play since 2014. Some of the Kansas faithful have already accepted and moved on to basketball season. (Next up: vs. Texas).9. Iowa State (2-8, 1-6) Trend: UpHead Coach Matt Campbell finally gets his first Big 12 conference win of the season. Even though it was against Kansas, this has to make some of the Cyclone fans happy. After finally tasting some success, Campbell will need to keep that momentum this weekend against Tech. (Next up: vs. TTU)8. Baylor (6-3, 3-3) Trend: Down (You can put a fork in this team)Prayers out to Seth Russell and I wish him a healthy, speedy recovery. Unfortunately, his team is in serious trouble and I am not sure if this program has the ability to turn things around. In my opinion, it is time to move on from the past and look toward the future. (Next up: vs. KSU)7. Texas Tech (4-6, 2-5) Trend: DownCoach Bro finds himself in a sticky situation once again. Texas Tech has two games left and they have to win out just to become bowl eligible. (Next up: @ ISU)6. Texas (5-5, 3-4) Trend: NeutralCharlie Strong lost this past weekend, so that means he is fired right? Texas has let another season slip away and the only thing left to play for is their head coach’s job. The good news is that they play Kansas this weekend. (Next up: @ KU)5. TCU (5-4, 3-3) Trend: NeutralTCU did itself a favor this past weekend by not playing and jumping up a spot in my rankings. Now that the Frogs have had some rest, they will have a big test this Saturday to try to get bowl eligible. Gary Patterson will be yelling a lot this weekend in Fort Worth, win or lose. (Next up: vs. OSU)4. Kansas State (5-4, 3-3) Trend: UpBill Snyder took a long nap last Saturday, so his team took the week off. Now he and his magic wand will head down to the land of the lost in Waco. (Next up: @ BAY)3. West Virginia (8-1, 5-1) Trend: UpAfter a huge win in Austin, some may wonder if Dana Holgorsen knew that his team actually won after this display. The bigger question is how many red bulls will Dana drink when Bob Stoops rolls into town? (Next up: vs. OU)Threat level: Holgorage pic.twitter.com/M9vkkCbgte— Deadspin (@Deadspin) November 12, 20162. Oklahoma State (9-1 I mean 8-2, 6-1) Trend: UpDoes Mike Gundy Still have a mullet? Yes. Is OSU still winning? Yes. At this point I am not sure which is growing faster, Gundy’s mullet or this team’s confidence. (Next up: @ TCU)1. Oklahoma (8-2, 7-0) Trend: UpAfter some early setbacks, the Sooners have been red hot in conference play. Oklahoma hasn’t lost a Big 12 game since early October of last season. Got to give some credit to Bob Stoops and his staff. Their next game will have a huge impact on the power rankings for next week.
