Mars is under assault by an armada of orbiters gathering intell from the planet with photons and radar beams. What kind of information has been seized recently?Dry rivers: Remember the networks of river channels that were telltale signs of water? Remember the hope for life those images generated? Some of those riverbeds could have been lava flows. Lava, understandably, doesn’t have quite the same astrobiological ring to it. Space.com reported on the most detailed analysis of the channels by NASA scientist Jacob Bleacher. “To understand if life – as we know it – ever existed on Mars, we need to understand where water is or was,” he said. Then he compared Mars channels with those on Hawaii. On Mauna Kea, he found “most of the features that were considered to be diagnostic of water-carved channels on Mars.” He also noticed evidence of collapsed lava tubes in some of the Martian channels. He believes his analysis allows making “a strong case that fluid lava can produce channels that look very much like water-generated features.” It’s important, therefore, not to jump to conclusions about water on the red planet, he said. His co-author Andy de Wet believes what they found applies to channels all over the Tharsis Bulge. While their study does not rule out some liquid water channels, “It may also have some implications for the supposed widespread involvement of water in the geological evolution of Mars.” National Geographic shows pictures of the channels.Hard water: There is water on Mars – if you’re talking about the hard kind (ice). PhysOrg echoed a press release from Jet Propulsion Laboratory about findings from the Mars Reconnaissance Orbiter (MRO) with its powerful HiRISE camera. “Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble.” Jeffrey Plaut of JPL explains its origin: “The hypothesis is the whole area was covered with an ice sheet during a different climate period, and when the climate dried out, these deposits remained only where they had been covered by a layer of debris protecting the ice from the atmosphere.” Nothing was stated about whether the H2O was ever liquid.Mars on the move: Mars is alive in one sense: the dunes are moving. Another press release from Jet Propulsion Lab described how scientists are identifying which sand dunes are traveling and which are marching in place. Some dunes, they claim, “have been stationary for 100,000 years or more.” How would they know, since observations go back only a decade or more? That’s only 1/10,000 the time claimed. The method used depends on crater counts (see 09/25/2007, 10/20/2005). “Examination of ripples at the edges of craters can show whether the ripples were in place before the crater was excavated or moved after the crater formed.” This gives relative ages; how are absolute ages estimated? Mars expert Matt Golombek said, “There’s enough of a range of crater ages that we can bracket the age of the most recent migration of the ripples in this area to more than 100,000 years and probably less than 300,000 years ago.” This depends on the current accepted scheme for assigning dates to craters based on their characteristics and densities. To keep the dunes static for such a long time, in spite of wind and dust, Golombek postulated the stable dunes are made of heavier particles, like the “blueberries” (concretions) found by the Opportunity rover: “The blueberries appear to form a [sic] armoring layer that shields the smaller sand grains beneath them from the wind.” It was not clear from the short press release why finer sand would not form on top of the armoring layer, or why the blueberries would form ripples at all if they are too heavy to be moved by the wind. In the finer sands of Meridiani Planum, “Opportunity has seen resulting changes in its own wheel tracks revisited several months after the tracks were first cut.”Mars-o-Phobia: The Mars Express orbiter of the European Space Agency took the highest resolution photos of Phobos, the larger of the Martian moons named for the Greek god of fear. Scientists fear that tidal forces will tear this low-density rubble pile apart some day. “Researchers suspect the moon is simply a collection of planetary rubble that coalesced around the Red Planet sometime after its formation,” BBC News article speculated. “Another explanation is that it is a captured asteroid.” Its density is so low, some planetary scientists believe “its surface probably hides many large interior voids.”JPL is working feverishly to assemble and test its next-generation rover before a scheduled launch in the fall of 2011. One chief goal of the Mars Science Laboratory (MSL), nicknamed Curiosity, will be to look for evidence of current or past life. Jennifer Eigenbrode, a Goddard scientist highlighted in a MSL press release, strung together a series of maybes in her description of the rationale: “Maybe life existed back then. Maybe it has persisted, which is possible given the fact that we’ve found life in every extreme environment here on Earth. If life existed on Mars, maybe it adapted very much like life adapted here.” None of MSL’s 10 instruments is prepared to look for life directly, however; but “SAM [Sample Analysis at Mars] has a key role of checking for carbon-containing compounds that potentially can be ingredients or markers of life.”We can play the maybe game, too. Maybe pigs had wings in the past and flew. Maybe they left no fossils. Maybe they evolved on Neptune and flew here. Maybe doesn’t cut it in science, baby. Let’s see your evidence. You can’t appeal to life in extreme environments on earth when discussing fictional life on Mars. That’s called begging the question. Show us life on Mars, then we can discuss how well adapted it is. Once again we find ad hoc theorizing to keep Mars old. The dunes move, so they had to cap them with blueberry armor to keep them as old as the craters tell them they must be. But even then, they can’t keep them older than 300,000 years – just 7% the assumed age of Mars. How come there are no craters 300,001 years old or more? The error bars are bigger than the bars. On a body that has global dust storms and volcanoes, it is a risky business to estimate crater ages. It is risky estimating the moon’s age by craters – and the moon has no atmosphere (read about some of the problems in crater-count dating in the 09/25/2007 and 10/20/2005 entries). Most egregious in planetary science reporting these days is the endless storytelling about life. The lava-flow theory of the channels will only be a temporary setback. Since the Maybe Game has achieved legitimacy, they can invent stories ad nauseum without needing any evidence. Maybe a crater hit the ice and melted it for a few days. Maybe life evolved on the fast track. Maybe it evolved antifreeze before the heat was all gone. Maybe MSL will find it.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0
3 June 2005More and more South Africans living and working in the UK are buying properties in SA with a view to returning home, with positive media coverage of SA and the local property boom among the reasons for the trend.Pam Golding Properties’ London office says about a quarter of all inquiries for South African homes come from expatriates wanting to invest in property back home.The agency told Business Day newspaper recently that this had been encouraged by positive reporting on SA in the British press, with extensive coverage of the country’s property market.Some 50% of Pam Golding Properties’ expat buyers plan to return to SA in the next year or two, says CEO Andrew Golding. The other half want to acquire a property as an investment for when they return home in the future.“Since the start of 2005 South Africa has received a great deal of good press in the UK media,” Golding said. “Most ‘holiday and homes abroad’ magazines have included extensive editorials on the property market in South Africa.”A place in the sun“A Place in the Sun”, an ITV Channel 4 programme, filmed footage in South Africa and carried a 12-page editorial in its January magazine on buying property in South Africa. Both editions have since carried editorials on the SA property market.Jawitz Properties MD Herschel Jawitz told Business Day that his group was “definitely seeing” an increasing number of expats both asking about and buying property in SA.“It is a result of the very positive sentiment that surrounds SA at the moment and the drive by organisations such as the Homecoming Revolution to draw South Africans back home,” Jawitz said.SA’s leading mortgage originator, Mortgage SA, says it has seen a marked rise in South Africans who live abroad applying for home financing through its website and call centres.“With the many excellent property websites showcasing South African property, increasing numbers of expats are comfortable buying property this way, then coming to us for financing,” Mortgage SA MD Saul Geffen told Business Day.A place to investMary-Jane Lefevre of the website Escape Artist says South Africa is at an exciting stage of development, with confidence in the country running high both among citizens and in the international community – and SA property is seen as an excellent investment.Reasons for this, according to Lefevre, include personal tax relief, lower property transfer duties, growth in household disposable income, low inflation and interest rates, strong domestic demand for housing, a rapidly growing middle class in previously disadvantaged communities, and continuing foreign demand.The latest Absa index of SA house prices reported strong growth, forecast to continue. SA’s basic home loan rate is currently at 11%, the lowest since 1980, and is unlikely to rise dramatically over the next few years.And getting finance has become a lot easier as competition between banks has increased, with banks offering 100% bonds and even loans with cost in certain cases.“South Africans thinking about emigrating should take into account the number of foreigners that view South Africa as a prime destination,” Lefevre says.“Given the distance and travel time to South Africa, the foreigners and expats investing in South African property must be basing their purchase decision on lifestyle.“Foreign buyers invest primarily as a result of lifestyle – climate, type and size of property and cost of living. But equally important is the interest rate environment, stability of exchange rates and consistent growth in property values. These are drawcards to foreign investors, and should also be seen as such by South Africans.”Average house prices in SA’s main centres, according to the Absa index, are as follows:Cape Town – R699 275Johannesburg – R635 123Pretoria – R676 984Bloemfontein – R494 449Durban – R639 707Port Elizabeth – R564 008According to Mortgage SA, South Africa has one of the best deeds registration systems worldwide, with an exceptional degree of accuracy and of tenure being granted.Property can be owned individually, jointly in undivided shares, or by an entity such as a company, close corporation, trust, or similar entity registered outside South Africa.How to buy South African propertyThere are a vast number of websites through which South Africans abroad can buy property at home. See the Related Links above right.But acquiring property from outside the country can be complicated. For this reason, the website Ask Harry has published “The Power of Property”, an “accessible, entertaining and comprehensive guide to the benefits and potential pitfalls of the SA property investment market, from the perspective of a non-SA resident or expat.”Ask Harry aims “to provide South Africans operating overseas with financially relevant information, to keep you informed so you can make better financial decisions, and eventually bring more money back to SA.”Order the Power of Property from Ask HarryAlso see Mortgage SA’s guide to buying SA property from outside the countrySouthAfrica.info reporter

Hyypia has no doubt about Liverpool title focusby Paul Vegas13 days agoSend to a friendShare the loveLiverpool Champions League title winner Sami Hyypia has no doubts about the team’s title focus.But while Liverpool stretched their lead over Manchester City to eight points going into the international break, Hyypia knows there is a long road ahead. He said, “It’s a great thing that no one left last summer – they kept all their big players. And, when I see them play, it looks like everyone wants to be there to play for this club and be in this team.“I watch them and it seems they are having fun playing at such an extraordinarily high level – but they are also demanding of each other. That’s why they won’t ease up.“I saw the episode with Mo Salah and Sadio Mane, but, far from thinking that was damaging to the dressing room spirit, I thought that showed how strong it is.“It just shows that everyone wants to win together and what a great group Klopp has built with that dynamic.“It’s always good to have that kind of openness where players can call each other out. That’s part of the culture of winning.“All successful teams have that desire, which means they demand more from each other.“I remember some sparks flying between players when I was at Anfield – and that’s only good for the team.” About the authorPaul VegasShare the loveHave your say

(Photo by Gene Sweeney Jr/Getty Images)Apparently wide receiver Devin Funchess is not the only recent Michigan football player who can throw down. After seeing Funchess’ impressive dunk on Instagram on Sunday, quarterback Devin Gardner decided to make one of his own.Gardner’s dunks are definitely impressive, especially for someone who focuses on another sport, but we’ll have to award this impromptu Wolverine dunk contest to Funchess. That vertical leaping ability is sure to impress NFL scouts in the coming weeks during the combine and other draft preparation events.

Since a gritty win in Philadelphia in the divisional playoffs on Jan. 4, 2014, the New Orleans Saints have gone 7-12, despite playing one of the NFL’s easiest schedules. According to our Elo ratings, they’ve suffered the sharpest decline of any NFL franchise since the start of the 2014 regular season. And after an 0-2 start this year, they have just a 15 percent chance of making the playoffs.Once upon a time, this would have been no big deal: The Saints have had a mostly miserable history, and they still rank 28th out of the 32 active NFL franchises in lifetime winning percentage. But we’d grown used to something different. Under quarterback Drew Brees, the Saints won a Super Bowl and were consistently in the championship conversation. Despite the occasional hiccup, they maintained a league average Elo rating (1500) or higher for more than six consecutive seasons, from Nov. 24, 2008, through Dec. 7, 2014.What happens when a franchise declines suddenly after such a sustained period of success? Can it sometimes be a false alarm? Can it replace a few parts and return to contention? Or is it doomed to years in the wilderness?The short answer: yes, yes and yes. It depends. It depends mostly on the quarterback situation and how the franchise manages it.I searched our all-time Elo ratings database for cases similar to the Saints’: teams that were very good for at least five consecutive seasons but then declined fairly quickly. (See the official criteria in the footnotes.1Specifically, I looked for cases since the AFL-NFL merger in 1970 in which a team:Had a streak of five or more years in which its Elo rating was always league average (1500) or higher,Had an average Elo rating of 1600 or higher during the streak, andDeclined to an Elo rating of 1450 or lower within a year of the streak breaking. 20077-97-96-10 Dolphins1980-87Marino (26)3.0 Bears1984-89Harbaugh (26), Tomczak (27)0.9 Saints2008-14Brees (35)??

Finally, I’ve listed how long it took the team to recover to contender status, which I define as having an Elo of 1600 or higher.

The median team took 3.1 years to recover to contender status; the average team3The St. Louis Rams have yet to achieve a 1600-plus Elo rating since the Kurt Warner years ended. For purposes of calculating this average, I’m using their current time of 10.8 years since their high-Elo streak was broken — but the Rams could take longer still to recover. took 4.1 years.But the average looks better than it otherwise would be because of a series of teams that had a stud quarterback in the prime of his career. Dan Marino’s Dolphins, John Elway’s Broncos, Donovan McNabb’s Eagles and Ben Roethlisberger’s Steelers each endured a rough patch. But those QBs were between 26 and 31 when the slump began, leaving their teams with plenty of time to adjust around them.Brees, by contrast, was 35 when the Saints’ Elo streak was broken last season. Past teams like the 1974 Chiefs, 1978 Vikings and 1986 Cowboys that held on to their aging QBs a year or so too long (sometimes through intermittent injuries) took longer to recover — and it was only once a new quarterback replaced the veteran that they did.The 2011 Colts, with Peyton Manning, and the 1999 49ers, with Steve Young, appear to be exceptions — both franchises rebounded pretty quickly after miserable seasons. But Young and Manning were injured so severely that their teams were forced to contemplate life without them — or at least had a convenient excuse to move on. Both had already played their last games for their clubs4And Young, forced into retirement, had played his last in the NFL. at the time their Elo streaks ended, it turned out.Brees is in the all-time inner circle of franchise quarterbacks: Only five others (Manning, Brett Favre, Marino, Elway and Tom Brady) have accumulated more passing yards with a single club. The problem is that a quarterback who’s been good for as long as Brees can obscure deterioration in the team around him. ESPN’s QBR includes a calculation of how much a quarterback is worth to his team in each game, relative to an average or replacement-level QB. This allows us to estimate how often a replacement QB would swing a game from a win to a loss, or vice versa. For instance, if the Saints win by 7 points and QBR estimates that Brees was worth 8.2 points, that’s a game where the quarterback made the difference. 20147-95-114-12 Eagles2000-05McNabb (29)3.0 49ers1981-99Young (38, injured)2.1 Basically, we’re looking for cases in which a quarterback plays really well in a close win.5Or plays poorly in a close loss. Brees has had a lot of those clutch wins.6The Saints don’t have an especially good record in close games under Brees, but he’s played extremely well in close games, win or lose, according to QBR. He’s salvaged a lot of wins from the jaws of defeat and kept the Saints competitive in games in which they’d otherwise have been blown out. Since 2006, his first year with the Saints, the team is 87-59 in the regular season.But with a replacement-level QB, they’d be 59-87 instead, according to this method. And the last few years would have been especially awful: The Saints would have gone 3-13 in 2012, 6-10 in 2013 and 4-12 in 2014 with Mark Sanchez or Brandon Weeden or some other replacement-level QB at the helm.Or … maybe not, since the Saints would have had a lot more money to invest elsewhere in the roster. Brees’s contract counts for $26.4 million against the salary cap this year, making it the biggest cap hit in the league. Because the top NFL quarterbacks are probably underpaid relative to the disproportionate value they can provide to their clubs, that’s not even all that terrible a contract so long as Brees is among the top half-dozen quarterbacks in the league — as he was until this season. But the minute Brees gets hurt, or reverts to league average (or worse) because of age, the Saints are left with a rotting carcass of a roster and a salary cap crisis.In fact, for all their irrationality in other areas, NFL teams have usually been able to anticipate these problems and have been remarkably unsentimental in parting ways with aging franchise quarterbacks in the salary-cap era. The first signs were in 1993, when Joe Montana was traded.7The salary cap would not officially be implemented until 1994, but NFL teams were aware of its impending impact at the time of Montana’s trade in April 1993. Then came Phil Simms — who, after a somewhat miraculous comeback season in 1993, was unceremoniously released the next spring. Troy Aikman might have retired anyway because of injuries, but he was ushered out the door. The same goes for Young, who was not welcome back in San Francisco. Warren Moon was passed around like a joint at a Phish concert toward the end of his career. Kurt Warner was benched. McNabb endured a fate worse than being benched: He was dealt to Washington. Favre had a reality-TV-style mess of a divorce from the Packers. Manning was let go once the Colts knew they had an opportunity to draft Andrew Luck.These NFL teams have generally recognized that it’s better to break up with an aging quarterback a year too early than a year too late. And almost none of those decisions look bad in retrospect.8The Colts releasing Manning without much of a fight might be the closest call, given Manning’s record-setting years in Denver, but they can’t exactly be unhappy with Luck. Brees may still have something left — quite possibly enough to lead another franchise somewhere to a deep playoff run — but it’s probably time for he and the Saints to move on from each other.Check out our NFL predictions for odds on every Week 3 game.
