FANTASTIC ASSIST MILAN (AP): Gonzalo Higuain is coming back into form at just the right time for Juventus. Higuain hadn’t scored for five matches before netting two against former club Napoli midweek as Juventus progressed to the Italian Cup final. And the forward netted another double to fire the Bianconeri past Chievo Verona 2-0 in Serie A yesterday. Juventus moved nine points clear of second-placed Roma, who visit Bologna today. Massimiliano Allegri will be hoping HiguaÌn can make it three out of three when Juventus host Barcelona in the first leg of the Champions League quarter-finals on Tuesday. “It will be a very difficult match in the Champions League. We’re facing a really great team, but we have to remain calm and get to it in top condition,” Higuain said. “As we respect them, they respect us, too.” He broke the deadlock in the 23rd minute, thanks to a fantastic assist from Paulo Dybala, who skipped down the right flank before pulling back for his teammate to fire into the far bottom corner. He had other chances to score before he finally got his second, six minutes from time, after more good work from Dybala in picking out Stephan Lichtsteiner, who crossed for HiguaÌn to control and curl into the bottom right corner. It was Juventus captain Gianluigi Buffon’s 616th Serie A appearance, moving him to second on the all-time list behind Paolo Maldini, who retired after 647. Other results: Atalanta 1 Sassuolo 1; Empoli 1 Pescara 1.
After scrutinizing rare meteorites for over a decade, a NASA astrobiologist decided to go with his announcement: he may have found alien life. Fox News began his story, “We are not alone in the universe – and alien life forms may have a lot more in common with life on Earth than we had previously thought. That’s the stunning conclusion one NASA scientist has come to, releasing his groundbreaking revelations in a new study in the March edition of the Journal of Cosmology.” There are only about nine CI-1 carbonaceous chondrites known. In the ones Dr. Richard B. Hoover has cracked open and studied, he has found “fossilized remains of micro-organisms not so different from ordinary ones found underfoot – here on earth, that is.” That’s one of the strange things about this story. If these are organisms that originated independently of earth, why would some of them be recognizable as “generic species here on earth”? Another problem is that the samples contain no nitrogen, an essential ingredient in life as we know it. All amino acids and DNA contain nitrogen. Hoover tried to be extremely careful with his samples, and expected a hotbed of controversy. He has invited scrutiny of his work by 100 experts, and wants thousands of scientists around the world to weigh in on its validity. Some, like David Marais, another NASA astrobiologist, are taking a wait-and-see attitude: “These kinds of claims have been made before, he noted – and found to be false.” Seth Shostak of the SETI Institute doesn’t rule out the possibility but recognizes the controversial claim will have far-reaching implications. He speculated that this might support panspermia of some sort: “It would suggest, well, life didn’t really begin on the Earth, it began as the solar system was forming.” That raises other questions of how and where environments in the early solar system could have been more conducive to life than planet earth. Rob Sheldon, a colleague of Hoover’s and an advocate of intelligent design, mentioned Hoover last December in his blog response on The Procrustean responding to the arsenic-life claim (12/02/2010). He indicated that Hoover probably would have expected alien life to be very different biochemically from earth life. On a different but related story, New Scientist and the BBC News speculated that “Meteorites ‘could have carried nitrogen to Earth’” in the form of ammonia carried on chondrites, chips of asteroids. Aside from questions left begging about whether these “missing ingredients for life” had anything to do with the origin of life, that story appears contradictory to Hoover’s, who found no nitrogen in his samples. “If someone can explain,” Hoover said, “how it is possible to have a biological remain that has no nitrogen, or nitrogen below the detect ability limits that I have, in a time period as short as 150 years, then I would be very interested in hearing that.”Is this another claim in the tradition of the Martian meteorite ALH 84001? Is NASA trying to get more funding (01/07/2005) for astrobiology? Possibly. They’ve probably learned how to be more careful by now and give the appearance of honest skeptical inquiry. In the early stages of controversial announcements, the Marais wait-and-see response is wise. The best advice is to look carefully at the raw data, check assumptions, and ask the right questions. The first question is to verify if this really is fossilized living material. The second is to rule out contamination. The third is to avoid jumping to conclusions and to consider all the possibilities. With the Martian meteorite, the similarities to cells were superficial and never widely accepted as anything more than coincidental shapes. Years after the huge flurry of media hype, after scientists found other ways the shapes could have been generated chemically, the hubbub died down. Now only a few scientists believe it (12/14/2000, 11/20/2001, 03/18/2002, 05/15/2002, 01/30/2004, 03/23/2006, 09/01/2009). Maybe this time things will be different. Hoover seems more cautious than McKay. What if the majority confirms that this was living material? Does it mean life evolved in outer space? No; it could have been created somewhere else, or it may be earth life that got here by a round trip. Creation scientist Walt Brown has a theory that asteroids and comets were ejected from earth at the time of the Flood, when hyper-pressurized water shot into space from the fountains of the great deep, carrying rocky material from the continental margins with it. It’s a speculative idea, but it’s one possibility to have life get out to space and back. As for the Fox News lead-in that “We are not alone in the universe,” good grief; this is about the solar system, not the universe (see extrapolation). Materialists will undoubtedly hype evolution, but the details revealed so far should be as puzzling to them as to their critics. No nitrogen, but similar to earth life? Astrobiologists have long tried to argue that life found elsewhere is bound to be very different from ours, but from the photos, these structures look remarkably similar to known bacteria. Nothing in creation science or intelligent design requires life only to be found on earth anyway (see initial thoughts by ID advocate Denyse O’Leary on Uncommon Descent). And why are these structures found only in a very rare class of meteorites, instead of all of them? Further speculation is unwise till the claim goes through the scrutiny of skeptical scientists. This commentary should only caution readers that healthy skepticism of spectacular claims is always in order, and to beware of being led down the primrose path by the media to answers without first asking the questions. Already Fox News’s exclusive story is echoing around the world on other news sources and blogs. Undoubtedly there will be more to say later about this claim. Have your Baloney Detector tuned and ready.Update 03/07/2011: Criticisms of the claim are starting to come in from the scientific community and from evolutionists (see Space.com, PhysOrg, and Fox News follow-up story), so don’t get too excited about alien bacteria just yet. Space.com also posted a gallery of past alleged proofs of alien life.Update 03/08/2011: New Scientist said there is “monster mud-slinging” going on among scientists about this claim. Jeffrey Bada pointed out that minerals can show “many non-biological artefacts” to confuse the observer. Alison Olcott Marshall [U of Kansas] said, “Morphology alone isn’t enough; geological context isn’t enough – you need all the pieces. You need multiple lines of evidence: morphology that is highly reminiscent of biology, a geological context that makes sense and strong chemical evidence.” New Scientist also hinted that the paper might have been a last gasp for the Journal of Cosmology, a journal deemed dubious by other astrobiologists. It may go out of business in a few months. This story is looking like a bright meteor – in and out of public attention in record time.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0
Top Reasons to Go With Managed WordPress Hosting Related Posts In any relationship, business or personal, first impressions are critical to getting off on the right foot. For startups, if a user gets a bad first impression of your website, that same sentiment will carry through to their opinion of your service. A few weeks ago we told you about some pointers to make sure your site’s registration process isn’t scaring away users. A recent post on web development blog Six Revisions focuses in on this issue by providing some techniques and best practices for creating and designing the perfect registration button.Besides being aesthetically pleasing, the design of the registration button can benefit from the following three suggestions, according to Six Revisions’ Dibakar Jana. First, the registration button needs to be above the fold and preferably in close proximity to a description of the main features of the site or product. There’s nothing worse than visiting a site you find intriguing only to waste precious time searching high and low for a poorly placed “register here” button. Don’t get caught up by placing too much information on your site’s landing page. Sometimes less is more. Secondly, an appealing registration button can go beyond being near the main features of the site by actually including those features in the button itself. By this, Jana means that buttons which say “Try now with a $2.00 credit” or “Buy Your Tickets Today” (examples Jana provides from InstantLoop and Vegas Uncork’d) speak louder than a simple “Sign Up” or “Register Here” button. You’re trying to convince visitors to your site that your product is unique, so try for some originality in your registration copy.Finally, aside from telling visitors what all the great features of your site are, show them why they should sign up. Do registered users stand to benefit from your site’s services more than casual browsers? Baramail beckons users to “Sign up now for a free account” while others like Myzeo offer “one year of FREE Coaching” in their sign up buttons. The more a user knows about what they’re getting into, and why registering for your site is a good idea, the more likely the are to follow through.Take Tumblr‘s registration process as a shining example of originality and excellent copy and design. A visit to the site’s homepage reveals their motto, “The easiest way to blog,” set in a large font size directly above an equally oversized registration form. The form, which sits beneath a cleverly placed “See 24 reasons why you’ll love Tumblr” link, asks for just an email address, a password and a personal Tumblr URL choice – all displayed in an absurdly yet amusingly large font size. Finally, the site invites registrants to “Sign up and start posting!” Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai… Tags:#How To#start chris cameron Whichever route you chose, just be original. Avoid using boring and simple “Join” buttons, or worse, a registration form which ends with the cold and thoughtless “Submit” button. People don’t want to feel like they are “submitting” their information to you, help them feel welcomed in a warmer, more personal way. If you need inspiration, be sure to check out Jana’s post on Six Revisions for dozens of examples, then pass your friendly suggestions along to your web designer. Remember, you only get one chance to make a first impression. 8 Best WordPress Hosting Solutions on the Market
Craig Kieswetter and Kevin Pietersen took England to their first world title in cricket as they thrashed Australia by seven wickets in the final of the World Twenty20 2010.England vs Australia, ScoresT20 World Cup – Full CoverageMan of the match: Craig KieswetterMan of the tournament: Kevin Pietersen (248 runs)Brief scores: Aus 147-6 (D Hussey 59; Sidebottom 2-26); Eng 148-3 in 17 overs (Kieswetter 63; Smith 1-21).Paul Collingwood’s men bowled and fielded sharply to restrict Australia to 147-6 after inserting them here at the Kensington Oval.Kieswetter (63, 49b) and Pietersen (47, 31b) — both of South African extract — added 111 to engineer what is Australia’s only defeat in a world championship final since their thrashing by Sri Lanka in 1996.The duo were dismissed within three runs of each other, causing the briefest of scares in the English camp. But Collingwood added 27 in 17 balls with Eoin Morgan to seal the win with three overs to spare — a massive margin by T20 standards — thus handing Australia their first defeat of the tournament after six straight wins.For Pietersen, who’s just become a father, this was meant to. His aggressive fifty against South Africa set the tone for England’s campaign after they had barely scraped through to the Super Eights.England have been the bridesmaid on many occasions, having lost ODI World Cup finals in 1979, 1987 and 1992, and the Champions Trophy final at home in 2006.Today, they stamped their authority on the game from the first over. Australia were reduced to 8-3 thirteen deliveries into the match, and England never let the momentum slip.advertisementDavid Hussey’s 59 (54b, 2×4, 2×6) and his 50-run stand with Cameron White’s 30 (19b) pulled Australia out of a messy start.Off-spinner Graeme Swann (1-17) complemented England’s pacers again with an economical spell in the middle overs.Earlier, Ryan Sidebottom had dismissed Shane Watson, caught at slip off the game’s third ball, and Brad Haddin caught down the leg in the third over.Haddin walked off looking disappointed at Billy Doctrove’s decision. Replays showed the ball had not hit Haddin’s bat as Kieswetter dived spectacularly to his left to take that catch. In between, Michael Lumb swooped in from cover to run David Warner out with a direct hit.Australian skipper Michael Clarke was caught brilliantly by Collingwood off Swann.The England captain flew to his left at short mid-wicket to hold on to a difficult catch, leaving Australia at 45-4 in the 10th over.England lost Lumb cheaply to Shaun Tait in the second over, but once Pietersen and Kieswetter were through, the trophy was in England’s grasp.By losing this game, Australia missed out on the chance to be the only team to hold all three ICC titles at once. Ricky Ponting had led them to victory in the 2007 ODI World Cup and the 2009 Champions Trophy.England’s 35-year wait to win a major title in cricket has ended and bodes well for them for next year’s World Cup in India.
