QPR have completed the club-record signing of Chris Samba from Anzhi Makhachkala.The former Blackburn defender, 28, has signed a three-and-a-half-year contract with the option of a further year and moves for a fee in the region of £12m.Rangers missed out when he joined Anzhi from Blackburn last year but Samba was unhappy in Russia, and the Loftus Road regime had long been planning a move to capture him in this transfer window.He made his name at Blackburn under Mark Hughes, who was confident of eventually bringing him back to England.Faurlin has moved to Italy.Rangers retained their interest following Hughes’ sacking as manager, while current boss Harry Redknapp is an admirer of the 28-year-old and discussed signing him while in charge at Tottenham.Meanwhile Palermo have completed the signing of QPR midfielder Alejandro Faurlin.He has joined the Italian club on loan for the rest of the season ahead of a possible permanent move there in the summer, when his future will be assessed.A popular member of Rangers’ promotion-winning side of 2011, Faurlin was recently told he was not in Redknapp’s plans.Redknapp is waiting to discover who his former club Tottenham are willing to make available ahead of tonight’s transfer deadline.Potential deals for a number of Spurs’ fringe players have been discussed in recent weeks.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 Follow West London Sport on TwitterFind us on Facebook
Planetary magnetic fields are astounding in their diversity. Mercury has a small global field (but should not); Venus, our twin, has essentially none; the gas giants all have fields but those of Uranus and Neptune are extremely tilted and off center, while Saturn’s is almost perfectly aligned with its pole axis. According to theory, this cannot be. Earth, fortuitously, has a perfect field to shield its inhabitants from cosmic rays and solar flares, but its strength is dropping rapidly. In this “golden age of planetary discovery,” we should soon be gathering more data to explain these mysterious phenomena. If trends continue, however, each solution will breed new problems. At this point, it does seem quite incredible that tiny Mercury should retain any global field at all, if it were really 4.5 billion years old. Note the surprise in Lincoln’s writing over this mystery: “against expectations…would have…should have…a rethink was needed.”(Visited 7 times, 1 visits today)FacebookTwitterPinterestSave分享0 Nature Feb. 121 restates a puzzle about Mercury known since the Mariner 10 encounters (1974-5): …why, against expectations, does Mercury have a global magnetic field? The planet’s diminutive size means that it should have cooled quickly after it formed. Any molten core would have become solid, or almost completely so. A magnetic-field-generating dynamo in an outer core (as is the case for Earth) should have long since seized up. But the news from Mariner 10 meant a rethink was needed, and since then attempts to account for the magnetic field have centred on how the core might have remained largely molten. Tim Lincoln mentions a new theory by Aharonson et al. published in Earth and Planetary Science Letters (2004) that maybe the original field was frozen into an uneven crust. We may not be able to tell until the MESSENGER spacecraft, launching this May, sends back its first data in 2007.
What makes signals go in one direction in neurons? It’s important, because a reflex signal from a bump on your knee needs to go in the direction of the controlling muscle and on to the brain, not any which way. Is there some kind of traffic cop that directs the placement of “one way” signs in nerve cells? Indeed there is. According to a press release from the University of Georgia, it’s the enzyme MEC-17. Researchers were not attempting to cure a disease or derive an application from finding this out; they just wanted to know how it works. How do neurons know which direction to send the signals? It appears that MEC-17, which they studied in roundworms, zebrafish and human cancer cells, is responsible for placing the traffic signs, called acetylation marks, on the cellular highways made of microtubules. The paths with lots of these marks are on the sending end, and the paths with few of them are on the receiving end. When the marks are not set properly, bad things happen: zebrafish develop neuromuscular defects, and humans are subject to debilitating neural diseases like Parkinson’s, Alzheimer’s and Huntington’s. This discovery may lead to new treatment strategies by enhancing or inhibiting the action of MEC-17. By noticing that MEC-17 works identically in animals as diverse as roundworms, fish and humans, the researchers deduced that “this microtubule acetylation process using MEC-17 is an evolutionarily conserved function.” Conserved means un-evolved.Saying evolutionarily conserved is like saying “aimlessly straight.” It’s a meaningless phrase we should not be duped into thinking signifies anything logical. This discovery emphasizes once again that things do not just happen; specific parts that are functionally exquisite are necessary for function. One question the research team appeared to overlook, though, is what controls MEC-17? If this enzyme puts up the signs, who is the foreman? We are certainly not consciously controlling much of this in our bodies. Most of it happens without our knowledge. It’s like the infinite regress question: who watches the watchers? The hierarchy of design must eventually stop at a Designer who is omniscient and omnipotent.(Visited 7 times, 1 visits today)FacebookTwitterPinterestSave分享0

The Carolina Panthers on Thursday released Steve Smith, the franchise’s all-time leading receiver, and he was snapped up Friday by the Baltimore Ravens — so it’s a good time to take stock of his career. The numbers say Smith is one of the best, and most underrated, wideouts of all time.As my former colleague Chase Stuart has repeatedly noted, Smith’s raw numbers have always understated his worth because of an unfortunate combination of injuries, a mediocre supporting cast at quarterback and receiver, and the team’s run-heavy strategy. But when Smith was healthy, he was as valuable as any pass-catcher.After the 2012 season — and before the 2013 season, when it became clear Smith had exited his prime years — Stuart found that Smith rated as the sixth-best receiver ever in two important yet under-the-radar stats: individual percentage of team receiving yards and receiving yards per team passing attempt. Neither metric is the final word on a receiver, but both reflect aspects that are central to the position.A player’s share of his team’s receiving yards is important because it represents a receiver’s market share of available statistics. As Pro-Football-Reference.com founder Doug Drinen once pointed out, receivers are the only players in football who directly compete with their own teammates for touches. (Other positions have their skirmishes, but they rarely battle while on the field at the same time.) So it really means something when a team funnels so many of its passes to one guy.Yards per passing attempt is also crucial. It accounts for how much a team throws the ball. Stuart and I conducted research last summer suggesting that when a team increases its passing attempts by 2 percent, its receivers will see about a 1 percent boost in production — a factor that can really add up at the extremes. Smith’s numbers were stunted relative to his peers because he played in rush-focused offenses that passed about 8 percent less than the NFL average over the course of his career.After we account for these handicaps, Smith looks like an all-time great. His 2005 campaign ranks extremely high in the aforementioned metrics, and his performance in 2008 stands out as one of the most commanding ever by a receiver. That year, Smith led the NFL in receiving yards per game despite the Panthers attempting the fewest passes in the league — the only time that’s happened since the NFL-AFL merger in 1970.Smith’s numbers have dropped off in recent years (no surprise; he’ll turn 35 in May), so it’s not clear how much production he’ll bring to Baltimore in 2014. But when he was at his peak, few receivers ever dominated their team’s passing game more.
The Ohio State Buckeyes lit up the scoreboard as they pushed their record to 4-0 Saturday, defeating the Florida A&M Rattlers 76-0.The Buckeyes started out fast, scoring early and often against the Rattlers. After throwing an interception on the first drive of the game, redshirt-senior quarterback Kenny Guiton recovered and threw four touchdown passes before the end of the first quarter, spreading the ball around in the process.Junior tight end Jeff Heuerman, junior wide receivers Evan Spencer and Devin Smith and senior running back Carlos Hyde all caught passes for scores from Guiton, helping OSU jump to a 34-0 lead.Guiton’s success this season in Miller’s absence is a result of how much he has pushed himself and developed, according to OSU coach Urban Meyer.“He pushed himself academically, and he’s an exceptional guy,” Meyer said of Guiton. “He’s an efficient player right now, he’s an incredible manager, coach on the field so, you know, his time came. It’s not because he had the buckeye in his pocket or his lucky T-shirt; it’s because he worked hard with the position coach to get ready for his opportunity and boy did he.”It was Hyde’s first action of the season after being suspended by Meyer for his involvement in an incident at a Columbus bar in July. Hyde finished the game with 41 yards on five carries to go along with his touchdown catch.With his return, one of the game’s story lines was how he was going to fit into the offensive system moving forward. Meyer addressed that following the game.“I think you have three (running backs) that are above the others right now, you have Jordan Hall, Rod Smith and Carlos Hyde are the top three backs,” Meyer said. “(Redshirt-senior running back) Jordan Hall gives you flexibility, too. I’m evaluating what to do.”OSU continued to pile it on in the second quarter, as Hall scored his second touchdown of the game on an 18-yard scamper to give his team a 41-0 lead.Guiton set the OSU record for touchdown passes in a game just before halftime, when he connected with Spencer in the back of the end zone for his sixth scoring toss. That score gave the Buckeyes a 55-0 lead at the break. Guiton completed 24 of 34 passes for 215 yards with six touchdowns and one interception, and said it was “a lot of fun” setting a record like that.“It’s a blessing. Like I said, thank God, thank the O-linemen. I had all day,” Guiton said. “The coaches wanted to come out throwing the ball around, I thank them for the trust they put in me to be able to do that, and I just trust the receivers and make plays.”With the game in hand, OSU’s backups started the second half and played the rest of the game. Freshman running back Ezekiel Elliot found the end zone for the first time in his OSU career in the third quarter on a 16-yard run. He scored again later in the quarter on a 13-yard run, as the Buckeyes took a 69-0 lead into the fourth quarter.Redshirt-freshman quarterback Cardale Jones ran 10 yards for a touchdown late in the game to make the final score 76-0.Starting redshirt-junior cornerback Bradley Roby said the defense’s goal was to not allow FAMU to score any points, and that it felt good to achieve that goal.“As a defense we shut them out,” Roby said. “That was our goal and we were able to accomplish that, so that’s always a good feeling, leaving a game with a goose egg.”A moment of silence was taken before the game to honor Maria Tiberi, an OSU student who was killed in a car accident Sept. 17. Meyer said they presented the Tiberi family with an OSU football helmet.“Once again with a heavy heart and sympathy and prayers for (the Tiberi) family,” Meyer said. “We gave them a helmet, and you wish you could do more for that family.”OSU is scheduled to start Big Ten play next Saturday against Wisconsin at Ohio Stadium. Kickoff is set for 8 p.m.
