By contrast, Richard Kerr’s summary article in Science was titled, calmly, “Mercury Looking Less Exotic, More a Member of the Family” (30 September 2011: Vol. 333 no. 6051 p. 1812, DOI: 10.1126/science.333.6051.1812). Judging from abstracts and reports, the following discoveries seem the most interesting: Science Daily: “Mercury Not Like Other Planets, MESSENGER Finds.” PhysOrg: “Epic volcanic activity flooded Mercury’s north polar region” BBC News: “‘Hollows’ mark Mercury’s surface.” The article begins, “Hands up who thought Mercury was just a dull rock circling close to the Sun? The latest data returned by Nasa’s Messenger probe shows that view couldn’t be further from the truth.” National Geographic: “Mercury ‘Hollows’ Found—Pits May Be Solar System First.” New Scientist: “Bright ‘hollows’ on Mercury are unique in solar system.” Space.com: “Planet Mercury Full of Strange Surprises” As boring as the moon? Just a burned-out cinder? Not Mercury. True to tradition for planetary exploration, the MESSENGER spacecraft has served up a plate of surprises about the innermost planet. In orbit since March, the ship is sending theorists back to the drawing board to figure out a number of puzzling phenomena, some unique to Mercury. Commentators fall into two categories: those that are flabbergasted, and those who say all is well. Science magazine published the first seven papers this week since the orbital tour began. Here were the headlines that resulted on various news outlets: Science Daily began its coverage with this summary that emphasized the theoretical challenges: Only six months into its Mercury orbit, the tiny MESSENGER spacecraft has shown scientists that Mercury doesn’t conform to theory. Its surface material composition differs in important ways from both those of the other terrestrial planets and expectations prior to the MESSENGER mission, calling into question current theories for Mercury’s formation. Its magnetic field is unlike any other in the Solar System, and there are huge expanses of volcanic plains surrounding the north polar region of the planet and cover more than 6% of Mercury’s surface…. Theorists need to go back to the drawing board on Mercury’s formation,” remarked the lead author of one of the papers, Carnegie’s Larry Nittler. “Most previous ideas about Mercury’s chemistry are inconsistent with what we have actually measured on the planet’s surface.” Science Daily ended with a quote by Sean Solomon: “Mercury is not the planet described in the textbooks. Although a true sibling of Venus, Mars, and Earth, the innermost planet has had a much more exciting life than anyone predicted.” It could be argued that planetary scientists need surprises to justify their jobs. Would the public continue to support space exploration if everything was as boring as predicted? Reporters, too, need to fan the hype with exciting headlines, or else advertisers might not get their return on investment. That doesn’t seem to be the case here. Long before this mission was conceived, planetary scientists had their theories based on the 1970s data from Mariner 10. And it’s not like they were all waiting with nothing to do before MESSENGER got there. Many of these things seem like genuine surprises that are important. While we join the revelry of new discoveries and applaud the many designers, engineers, scientists and assorted workers for a job well done getting this ship into orbit and delivering the data, we think much of the hand-wringing about textbooks being blown out of the water is a result of thoughtless adherence to the old Moyboy* Myth, that old Law of the Misdeeds and Perversions that Cannot be Altered. To keep the data in the ASS (age of the solar system, 4.5 billion years), believers have to tell fantastic tales: lava erupted quickly and suddenly all over the north, then shut off for billions of years, while depressions are being hollowed out in a process that could still be ongoing today. Inside a planet smaller than Saturn’s moon Titan, they have to keep an iron core liquid long enough so that a global magnetic field can survive. They have to make a planet out of volatile elements that were believed not possible to exist so close to the sun, but then keep vast deposits of it intact after billions of years of solar heat and bombardment. MESSENGER is just the messenger. The sender, Mercury, is saying, “Think outside the moyboy* box.” *Millions of Years, Billions of Years(Visited 33 times, 1 visits today)FacebookTwitterPinterestSave分享0 Hollows: The hollows spoken of are unique structures found within some craters. Irregular in shape and up to miles across, these depressions with sharp rims, often found in clusters and found across Mercury, appear to be collapse pits – as if volatile substances escaped from underground and caused surfaces to fall. The closest analogues are on Mars, where similarly shaped features result from sublimation of ice at the poles; but here on Mercury there is no ice. Science Daily called them “an unexpected class of landform on Mercury and suggest that a previously unrecognized geological process is responsible for its formation.” New Scientist said of them, “They may have been formed by processes still active today, and change our view of the small rocky planet’s history.” Science Daily quoted a scientist who believes they are actively forming today – further evidence that “Mercury is radically different from the Moon in just about every way we can measure.” National Geographic quoted David Blewett (Johns Hopkins): “”The old thinking was, Oh, Mercury, it’s an old burned-out cinder and not so interesting… here’s this jaw-dropping thing that nobody ever predicted.” Sulfur: Space.com introduced this surprise: “Mercury is not just hellishly hot but apparently covered in brimstone. A vast part of the planet is covered with dried lava – enough to bury the state of Texas under 4 miles of the stuff, scientists say.” Richard Kerr in Science said “Surprisingly, it has 10 times the sulfur of Earth’s rock.” Reducing conditions: Mercury doesn’t fit another expectation. Richard Kerr explained, “The combination of high sulfur and low iron in Mercury’s rock must have come from minerals that could have existed only if Mercury formed under chemically reducing conditions. That sounds bizarre, because all the other rocky planets formed under the opposite conditions: oxidizing ones.” He was quick to find a scientist who “showed that probably only water-free, organics-rich, comet-dust–like stuff would have survived near the sun to make Mercury. With no oxygen atoms from water around, reducing conditions would have prevailed.” Still, it makes Mercury a special case compared to nearby Venus and Earth. Potassium: Science Daily explained why elevated potassium levels seen on the surface is a challenge to explain: “Measurements of Mercury’s surface by MESSENGER’s X-Ray and Gamma-Ray Spectrometers also reveal substantially higher abundances of sulfur and potassium than previously predicted. Both elements vaporize at relatively low temperatures, and their abundances thus rule out several popular scenarios in which Mercury experienced extreme high-temperature events early in its history.” Lava flows: Evidence of volcanism had been observed on the previous three flybys, but the extent of lava plains exceeded expectations – some five million cubic kilometers. The BBC News had a comparison some angry voters might like: “This is enough lava to cover the City of Washington DC to a depth of over 26,000 km, which is about 72 times higher than the orbit of the International Space Station.” Seen primarily in previously-unseen northern regions, the lava is thought to have oozed out of fissures, rather than coming from eruptive centers that produce familiar cone-shaped mountains. Space.com explained, “Based on the way this lava apparently eroded the underlying surface, the researchers suggest it rushed out rapidly.” Lead scientist James Head (Brown U) thinks the flows date from billions of years ago, but remarked, “We can’t say if it took 2.7 days or 15 years or any exact time from orbit, but it wasn’t hundreds of millions of years.” Why extensive volcanism would turn on like that, last a few years, and then stop – only to remain unchanged for billions of years – seems odd. Magnetic field: Of the rocky planets, only Earth and Mercury have global magnetic fields. Unlike other magnetic fields, Mercury has one that is only 3% offset from its polar axis, but is inexplicably displaced some 300 miles northward from the center of the planet. Mercury’s is also much weaker than Earth’s – too weak to provide protection from the solar wind. See Science Daily for details.

LOS ANGELES — The U.S. is on track to finish the year with an annual decline in home sales for the first time since 2014.Home sales have plunged over the past 12 months and many economists forecast sales will weaken further in 2019.The housing market is slowing as would-be buyers struggle with rising borrowing costs and a persistently low number of properties on the market.Glenn Kelman, CEO of Seattle-based real estate brokerage Redfin, recently spoke to The Associated Press about the state of the housing market and why he expects first-time buyers will continue to struggle next year. The interview has been edited for length and clarity.Q: How do you see the housing market’s trajectory next year?A: The housing market is probably the weakest sector of the U.S. economy and the $64,000 question is just whether housing is going to bring down the U.S. economy or the U.S. economy is going to bring housing back up. People have good jobs and corporations are making money. If the stock market rebounds, you’re going to see a reasonable housing market next year. It will still be soft, but it won’t be catastrophic. If, on the other hand, housing undermines consumer confidence generally; people start feeling poor because their home has declined in value; and a huge sector of the economy for building and selling housing enters a recession, then you can see the start of a much larger cycle.Q: Do you see first-time buyers having an easier time?A: They’re going to have a harder time. There’s so much inventory that’s rate-locked. The spread between 3.5 per cent and the current mortgage rate, as that widens, it will just be a stronger and stronger incentive for people to hold on to their homes forever. When they want to move, they’re going to rent them out, rather than sell them.Q: What’s it going to take to fix this shortage in affordable housing?A: I view much of our economic policy as a way to defend the wealth of baby boomers. People get up in arms about protecting the value of their home and making sure that it increases. When the city wants to increase density, everybody living in a single-family home, who is usually between the ages of 40 and 65, absolutely freaks out and prevents that construction. And in some ways that’s just acting as a cartel where the people who hold the good prevent more supply of that good from reaching the market and maintain artificially high prices. What I’m hopeful about is just this idea that Americans aren’t trapped in a single city. If you go to almost any city hall, the only pocketbook issue that the middle class is up in arms about is the cost of housing. And every mayor is trying to solve that problem. And the cities that are solving it best are in the middle of the country, so that’s why you’re seeing this migration from coastal cities into the centre of the country. I think it’s going to depolarize us politically.Q: Any major trends that you see accelerating next year?A: Tech companies are going to increasingly be called to account for how we deal with the prosperity created by technology. We should want high-paying jobs, but when housing prices blow up in Boise or Salt Lake or Denver, a mob forms and they want answers and the people they ask the answers from are Twitter and Amazon and Redfin. The idea that we can say that’s not our problem isn’t working very well right now. There just has to be a better alliance between tech and government on this. It boils down to higher taxes for tech.Alex Veiga, The Associated Press
Palm Beach: Threatening drastic action against Mexico, President Donald Trump declared he is likely to shut down America’s southern border next week unless Mexican authorities immediately halt all illegal immigration. Such a severe move could hit the economies of both countries, but the president emphasised, “I am not kidding around.” “It could mean all trade” with Mexico, Trump said when questioned Friday by reporters in Florida. “We will close it for a long time.” Also Read – Saudi Crown Prince ‘snubbed’ Pak PM, recalled jet from USTrump has been promising for more than two years to build a long, impenetrable wall along the border to stop illegal immigration, though Congress has been reluctant to provide the money he needs. In the meantime, he has repeatedly threatened to close the border, but this time, with a new surge of migrants heading north, he gave a definite timetable. A substantial closure could have an especially heavy impact on cross-border communities from San Diego to South Texas, as well as supermarkets that sell Mexican produce, factories that rely on imported parts, and other businesses across the US. Also Read – Record number of 35 candidates in fray for SL Presidential pollsThe US and Mexico trade about USD 1.7 billion in goods daily, according to the US Chamber of Commerce, which said closing the border would be “an unmitigated economic debacle” that would threaten 5 million American jobs. Trump tweeted Friday morning, “If Mexico doesn’t immediately stop ALL illegal immigration coming into the United States through our Southern Border, I will be CLOSING the Border, or large sections of the Border, next week.” He didn’t qualify his threat with “or large sections,” stating: “There is a very good likelihood I’ll be closing the border next week, and that is just fine with me.” He said several times that it would be “so easy” for Mexican authorities to stop immigrants passing through their country and trying to enter the US illegally, “but they just take our money and ‘talk.'” Homeland Security Secretary Kirstjen Nielsen suggested Trump was referring to the ongoing surge of mostly Central American families heading north through Mexico. Many people who cross the border illegally ultimately request asylum under US law, which does not require asylum seekers to enter at an official crossing. Short of a widespread shutdown, Nielsen said the US might close designated ports of entry to re-deploy staff to help process parents and children. Ports of entry are official crossing points that are used by residents and commercial vehicles. “If we have to close ports to take care of all of the numbers who are coming, we will do that,” Nielsen said. “So it’s on the table, but what we’re doing is a very structured process based on operational needs.” The White House did not immediately respond to questions about whether Trump’s possible action would apply to air travel. Trump’s latest declaration came after Mexican President Andres Manuel Lopez Obrador said his country was doing its part to fight migrant smuggling. Criminal networks charge thousands of dollars a person to move migrants through Mexico, increasingly in large groups toward remote sections of the border.
New Delhi: Behind every successful journey, there is a lot of struggle and heartbreak that goes unnoticed. Done with the celebration and the post-match presentation at the Rajiv Gandhi International Stadium on Sunday, Mumbai Indians skipper Rohit Sharma took a trip down the memory lane as he walked back into the dressing room after lifting the IPL trophy for a record fourth time. With the noise settling down and the feeling of being the champions sinking in, Rohit took the boys down to May 20, 2018. A loss to Delhi Capitals (then Daredevils) at the Feroz Shah Kotla saw the Mumbai Indians’ journey end as they failed to qualify for the playoffs. This very team, which on Sunday was the cynosure of all eyes, had people questioning their ability and prowess. But the skipper had the back of the boys when things went downhill and the boys repaid the faith with the title this season. Also Read – We will push hard for Kabaddi”s inclusion in 2024 Olympics: RijijuIt has been learnt that Rohit, after Sunday’s summit clash, in his speech inside the dressing room mentioned how he believed in the boys even when the chips were down and he was extremely proud of how they came back with a bang this season. “Last year after we couldn’t qualify for the playoffs in Delhi, I told you all that this is a damn good team we have. Our run (2018 season) didn’t go as expected, but I believed that this team can do wonders. Today we have shown our character. This is the hallmark of our team. We believed in each other till the last minute. Each one of you was exceptional this season and I am just the lucky guy who gets to lift the trophy. So, thank you to all the boys, support staff, management and everyone for being a part of this wonderful and historic journey,” Rohit said in his victory speech to the boys.

Speaking to the team in a huddle after the game, both the owners had told the boys to believe in themselves and their abilities. In fact, Akash had told the boys to avenge the defeat when the two teams would meet again at the Wankhede Stadium in a week. Not only did the boys avenge the loss with a resounding nine-wicket win, but they also went on to win the remaining two games of the season to be crowned champions.
LONDON (AP) — Tiki Gelana felt the marathon slipping away when she tumbled on the rain-slickened street.Around the halfway point of the race, the Ethiopian was knocked down by another runner as she reached for her water bottle, a hard fall that bloodied her right elbow. Already aching, Gelana thought about pulling out. Instead, she found new motivation, and headed on down the road.Gelana recovered from the fall to win the Olympic marathon on Sunday in a race that began in a downpour, was briefly brightened by sunshine and ended in another drenching rain.She was soaked as she crossed the finish line, but she didn’t seem to mind, raising her hands high to celebrate after navigating the rainy course in 2 hours, 23 minutes, 7 seconds to hold off Priscah Jeptoo of Kenya by five seconds. Tatyana Petrova Arkhipova of Russia won the bronze in the typical London weather.“When I fell, I said, ‘Oh, wow, I’m not going to finish,”‘ Gelana said through an interpreter. “But I just concentrated on running. All of a sudden, I made it.”Gelana said she loved running in the rain. “I have been doing that since I was a small child,” she said, a bandage on her elbow. “I enjoyed my run.”There was a small group of runners in a bunched pack over the last three miles. But with the finish around the bend, Gelana made her move, grimacing as she surged to the front. With the rain picking up – going from a light drizzle to a deluge – she kept glancing over her shoulder to see if Jeptoo was gaining ground.She wasn’t. No one could catch Gelana as she easily coasted across the line to win the biggest race of her life and Ethiopia’s second Olympic gold medal in the women’s event.Read more: Sports Illustrated

AFC Bournemouth midfielder Sam Matthews has become Bristol Rovers second signing of the summer after he signed a contract with the club. A deal that will take effect from July 1.Manager Darrell Clarke was delighted to have Sam agree to the transfer, according to Gazette series he said:“Sam is a very talented young player whose progress I have monitored for a while now.“He has worked hard and, learnt a great deal, from his time at Bournemouth and, of course, during his loan spell at Eastleigh in the National League last season.“We had to compete with a number of other clubs for his signature and I am delighted that he has chosen to join us “His arrival will intensify competition for first team places at the club and I look forward to working with him.”Match Preview: Bournemouth vs Manchester City Boro Tanchev – August 24, 2019 English champions Manchester City travel to Bournemouth for their encounter of the third Premier League Matchday.Upon signing, Sam continued;“I was on loan at Eastleigh last season and played quite a lot of games in the National League and then had some interest from other clubs, Rovers being one of them.“I met with Darrell Clarke over the summer, had a chat and as things progressed it’s resulted in me signing today and I’m really happy to get it done.“He told about the club itself, the squad the he has here and told me there’s great spirit amongst the players.”
Republic of Ireland head coach Martin O’Neill has revealed his side deserves to lose after they suffered a thrashing at the hands of Wales.The Irish team were humiliated 4-1 at the hands of Wales who gave Ryan Giggs a victory in his maiden competitive game as head coach of the team.Ireland were without several regulars as they visited the Cardiff City Stadium on Thursday night, which was something O’Neill attributed as a major factor in their heavy defeat.Players including Southampton’s Shane Long were absent from his squad, which produced a very disappointing performance from the one which had seen them qualify for the World Cup qualifying play-offs on their last visit, less than a year ago.Report: Former Liverpool striker Heskey reveals all George Patchias – September 10, 2019 Former Liverpool striker Emile Heskey reveals all in his new book.In Heskey’s new book “Even Heskey Scored,” serialised in the Guardian, the player talks,…“We were well beaten, it was difficult. We were missing some key players but were still well beaten.” O’Neill told Sky Sports.“We set out with good intentions, they scored fairly early on and their second was a world-class goal from a world-class player. That sets you back, and from there it’s tough. It was a hard evening.”“I think that we’re unable to be missing five or six Premier League players and put ona real bug show, we need to be at full-strength if we can be. I can’t remember the last time we were, but I don’t think we’ve been as decimated as this.”
