If one molecular machine by itself is a wonder, what would you think of groups of them playing in concert? Recent papers and news articles are claiming that’s what happens in living cells: molecular motors coordinate their efforts. Science Daily led off a story on this by saying, “Even within cells, the left hand knows what the right hand is doing.” Researchers at the University of Virginia said they “found that molecular motors operate in an amazingly coordinated manner” when “simple” algae named Chlamydominas need to move with flagella. This contradicts earlier models that pictured the motors competing with each other like in a tug-o’war. “The new U.Va. study provides strong evidence that the motors are indeed working in coordination, all pulling in one direction, as if under command, or in the opposite direction – again, as if under strict instruction.” It almost requires imagining a conductor or foreman guiding the process. Understanding it could help with treatments of neurodegenerative disorders. The article did not mention evolution. The researchers published their work in PNAS.1 Another cellular system reported by Science Daily refers to coordination of independent parts. DNA transcripts made of messenger RNA emerge from the nucleus in 3-D clumps. These need to be “straightened out” into a linear code that can be read by the ribosome. Research at Rockefeller University shows that one of the 30 kinds of proteins in the nuclear pore complex “magnetically” attaches to the transcript when it passes through the gate, joining an unwrapping machine called a helicase “to form a machine that unpacks balled-up messenger RNA particles so that they can be translated.” Here’s how Andre Hoelz described the action: “We found that the messenger RNA protein package and Nup214 competitively bind to the helicase, one after the other.” Each binding strips one protein off as it passes through. “The process is akin to a ratchet mechanism for messenger RNA export,” Hoelz said. Failures in the mechanism, again, were said to be implicated in disease. Once again, also, the article said nothing about evolution.1. Laib, Marin, Bloodgood and Guilford, “The reciprocal coordination and mechanics of molecular motors in living cells,” Proceedings of the National Academy of Sciences USA, published online February 12, 2009, doi: 10.1073/pnas.0809849106.The Darwinists have their chance to show up and explain the evolution of coordinated action of multiple parts needed for function, the failure of any component of which leads to disease or death. The intelligent design team showed up. Where’s the evolution team? It’s like in sports. Fail to show up and you forfeit.(Visited 15 times, 1 visits today)FacebookTwitterPinterestSave分享0

LEON, Nicaragua – Two days after protests began in Nicaragua in April, a foreign auto components company was meeting at a hotel in the city of Leon when smoke from a burning university building just a block away billowed above the hotel’s colonnaded courtyard.The visitors quickly cut short their event and began changing their travel plans to exit Nicaragua. Within three months, the El Convento hotel itself was forced to close for lack of business, as a sister hotel in the same city had in June.Nicaragua’s economy has been devastated by the nearly five months of unrest sparked by cuts to social security benefits that quickly evolved into calls for President Daniel Ortega to step down.In June, the country’s economic activity was down 12.1 per cent compared to a year earlier, according to the central bank. Economists estimate 200,000 jobs have been shed, including as many as 70,000 in the tourism sector, which has become Nicaragua’s top source of foreign currency in the past two years.Revenue at hotels and restaurants plunged 45 per cent in June compared to 2017, according to Nicaragua’s central bank. Similarly, construction suffered a 35 per cent drop and retail 27 per cent. Some $900 million in deposits fled Nicaragua’s banks. They responded by tightening their lending to preserve liquidity, thus also contributed to the economic slowdown.Nicaraguan Union of Agricultural Producers says more than 12,000 acres of private land have been occupied by government supporters in what business leaders have called confiscations in revenge for their support of the protesters.The producers say 91 per cent of the land occupied by squatters was used for farming and livestock.Victor Hugo Sevilla, the general manager of both Leon hotels, continues checking email, but said “I haven’t gotten any requests from foreigners for reservations. We have received five, maybe eight, rate inquiries from domestic (travellers), but no firm reservations.”Leon, Nicaragua’s second-largest city, was among the places where protests and roadblocks were most intense. From the beginning, those protests were met with violence from riot police and civilian government supporters. In July, they violently cleared the roadblocks and ran protesting students off occupied university campuses.More than 300 people have been killed in the unrest, according to human rights groups. The government calls the protesters “terrorists” and says it defeated an attempt to drive Ortega from office that was sponsored by the U.S. government and domestic opposition, including some in the private sector.Ortega conceded this month that the roadblocks and unrest have cost the country jobs. In an interview with Spanish news agency EFE, he said domestic tourism was starting to return, but “where there has been more of a problem is in attracting international tourism, because this situation tends to repel the tourists.”A major factor has been that the countries that send Nicaragua’s big-spending foreign tourists, including the U.S., Canada, Spain and England, issued travel warnings urging their citizens to avoid travel to Nicaragua.Major airlines such as American and United cut their flights to Managua from three per day to one. Spirit, Delta and other carriers trimmed their flights as well, said Jose Adan Aguerri, president of the Superior Council for Private Enterprise.The council, which is Nicaragua’s main business chamber, joined the call for a national strike Sept. 7. The Civic Alliance, formed to represent a broad swath of Nicaraguan society in a stalled dialogue with the government, said the strike aimed to push the government back to dialogue and to protest the arrest of alliance members and other political prisoners.The country’s primary tourist destinations like the colonial gem Granada and the Pacific coast surfer paradise San Juan del Sur began feeling the consequences of the unrest almost immediately. Hotels and restaurants cut back hours, then days and eventually closed completely.For years, Ortega enjoyed a relatively stable relationship with private business. Since returning to power in 2007, the one-time Marxist rebel commander had softened his views and largely left Nicaragua’s private sector to do what it wanted.The relationship was criticized by some as a tacit agreement to keep the country’s business elites out of politics. In an interview in July with Venezuela’s Telesur network, Ortega said his understanding with Nicaragua’s private sector had been strictly economic and not political.In April, however, the country’s business interests, caught off guard by the social security system changes, quickly joined the opposition. As the social and political crisis deepened, the private sector became increasingly outspoken in calling for Ortega to move up elections.Mario Arana, director of the Nicaragua Association of Producers and Exporters and a former head of the central bank, said the private sector decided to get more involved when student protesters were killed.“When there was an overreaction here to a civil, peaceful protest by the students, where people began to lose their lives, society suffered a social explosion where the private sector aligned with the people,” he said. “The private sector is committed to trying to find a negotiated exit from the crisis.”Juan Sebastian Chamorro, who leads the Nicaraguan Foundation for Economic and Social Development, said the government has shown signs that it recognizes the severity of the economic impact. It has issued new debt, adjusted rules to tighten the selling of dollars and cut public spending as it forecasts a 10 per cent drop in tax revenue.Whether any of that will be enough to stop the economy’s slide is doubtful unless it’s accompanied by a political solution that restores stability, experts said.On Wednesday in Washington, the Organization of American States called on Nicaragua’s government to co-operate with teams investigating human rights abuses and a working group created by the body to support a national dialogue.Nicaragua’s ambassador to the body, Luis Alvarado, responded that the government does not recognize the existence of the working group and therefore had nothing to answer to.For years Leon had been at best a day trip for foreign tourists beginning to explore better-known Granada or San Juan del Sur. But the city had worked hard to get attention and Art Collection Hotels had bet on its prospects by opening its second hotel, La Recoleccion, in 2017.“We had high expectations for this year,” said Sevilla, the manager of the closed hotels.He had 113 employees between the two properties. They were able to suspend 67, which will enable them to come back without losing any benefits of seniority, but the rest were laid off. He has remained in touch with some of the workers. Those still around are taking whatever work they can find, but he estimated at least half left the country, with most of those seeking tourism sector jobs in Costa Rica.The hotels have 190 reservations for November — the start of the high season — but that’s less than half what they had in November last year. Still, he hopes they can start working their way back again in October. Even if that works out, he predicts a slow climb back to normalcy.Cafes and shops selling handicrafts around Leon’s historic centre were open this week, but a number of hotels and hostels in the area were shuttered.“I think it will take at least 12 months, maybe more, to be able to restart the tourism engine,” he said.___Sherman reported from Mexico City.

New Delhi/Mumbai: Air passengers face the grim prospects of high air fares and fewer flight choices as several airlines cancel operations due to a number of reasons including the grounding of 737-MAX aircraft. According to industry insiders, some sectors have shown a rise of more than 100 per cent in last minute bookings. “With an unprecedented number of planes now grounded due to various factors, reduction in seat capacity has led to an increase in fares overnight. Last minute airfares on Wednesday increased to more than 100 per cent on some key routes like Delhi-Mumbai, Mumbai-Chennai, Mumbai-Kolkata and Mumbai-Bengaluru as compared to same time last year,” said Aloke Bajapi, CEO and Co-founder, ixigo. Also Read – Maruti cuts production for 8th straight month in Sep “Spot fares for Mumbai-Chennai are touching Rs 26,073 as opposed to Rs 5,369 the same time last year. High airfare patterns are expected to continue in the short term with Holi and summer school holidays round the corner, resulting in an increased demand.” Operations of airlines like SpiceJet and Jet Airways have been hit due to the government’s Wednesday decision to join a global grounding of 737-MAX aircraft following a crash in Ethiopia. Also Read – Ensure strict implementation on ban of import of e-cigarettes: revenue to Customs In India, SpiceJet and Jet Airways operate 17 Boeing 737-800 MAX aircraft – Spice (12) and Jet (5). A part of Jet fleet has already been grounded due to other reasons. The grounding led SpiceJet to cancel 14 flights on Wednesday. This number is expected to touch 32 on Thursday. Apart from SpiceJet, Jet Airways, which faces financial challenges, has already grounded four more aircraft over non-repayment of dues to lessors, taking the total to 32. The company in BSE filings has said that its 19 aircraft were grounded in February over non-repayment of dues to lessors, while 13 aircraft were grounded this month, taking the total to 32. The Jet Airways Group operates a fle et of 123 aircraft. However, around 50 planes are said to be non-operational due to a host of reasons, including lack of spare parts. IndiGo faces massive turbulence of pilot shortage, leading to truncated flight schedule Earlier, the airline said that 30 of its flights which have been affected represent only 2 per cent of its network. It has decided to curtail its schedule till March 31, by about 30 flights a day. “As a proactive measure, IndiGo has decided to continue its curtailment until the end of March. This measure has already been implemented and passengers informed,” the airline said in a statement. “These medium term cancellations have been made to minimise the impact on passengers as alternative travel options have been offered well in advance. The operations will be normalised by the start of the summer schedule.” For sometime now, Air India has grounded 17 aircraft due to technical reasons. On Wednesday, the government had advised domestic airlines not to go in for predatory air fare pricing as several 737-MAX aircraft were grounded due to safety reasons. Civil Aviation Secretary Pradeep Singh Kharola said: “We have advised the airlines… that they should not use it (grounding) as a reason to jack up their fares.” “They have promised they will go as per normal routine. DGCA has just said that it will be monitoring all the sectors very closely.”
Iowa running back Mark Weisman (45) rushes down the field during a game agianst Minnesota at TCF Bank Stadium Sept. 28. Iowa won, 23-7.Credit: Courtesy of MCTThrough its first six games, Iowa (4-2, 1-1) is the only member of the 125-team Football Bowl Subdivision who has not allowed a rushing touchdown yet this season. Ohio State’s 11th ranked rushing attack plans to put the Hawkeyes’ streak to the test.The chance to be the first team to reach the end zone on the ground against Iowa this season is “definitely an incentive” for the Buckeye offense, redshirt-senior center Corey Linsley said.“Coaches don’t need to say too much. They just put a piece a paper on our desk and say, ‘They haven’t allowed a rushing touchdown,’ and we kind of get it,” Linsley said.Iowa has one of the nation’s best defenses, ranking ninth nationally in total defense with an average of 290 yards allowed per game.“They’re in the top 10 in America and our kids know that,” OSU coach Urban Meyer said of the Iowa defense. “We’re working really hard. They’re good. They’re really sound.”Linsley said the matchup with Iowa’s defensive line will be the toughest opposition the OSU offensive line has faced all season.“They’re physical, they’re tough, they’re big,” Linsley said. “In terms of toughness, in terms of things that we preach and the values that we take, hold to, that’s what they’re about as well on the defensive line.”Iowa coach Kirk Ferentz said he thinks the OSU offensive line will challenge the Hawkeye defense.“It’s going to be a tough matchup for us,” Ferentz said. “They look good. They’re big, tall, imposing guys. They look like an NFL line, and they (are) extremely well-coached.”Overall, Ferentz said OSU’s scoring offense, which ranks sixth in the FBS with an average of 46.8 points per game, is “extremely talented.”“Look at their offense, pick a position and try to find a weakness,” Ferentz said. “Good luck on that one.”The Hawkeyes are going to have to be prepared for numerous running threats from the OSU offense to keep their streak alive.Senior running back Carlos Hyde is expected to lead the Buckeyes’ rushing attack Saturday after rushing for 168 yards and three touchdowns against Northwestern Oct. 5.Additionally, senior running back Jordan Hall, who leads the Buckeyes with 69 rushing attempts, 427 rushing yards and eight touchdowns this season, is expected to be back on the field Saturday, Meyer said, after missing the game against Northwestern with a joint issue in his knee.“His first way of assisting the team will be on special teams and then he can certainly complement Carlos and be also involved in third downs,” Meyer said of Hall.As a passer, junior quarterback Braxton Miller has completed 49 of 75 passing attempts for 609 yards and six touchdowns with two interceptions this season. His ability to make plays passing the ball will make it tougher for the Hawkeyes to defend the run, Ferentz said.“They pose a lot of problems in a lot of different areas,” Ferentz said. “They can throw it very effectively … (Miller is) a great running threat, as is (Hyde) … It makes it tough to play defense. You can’t really tilt your team one way or the other.”Ferentz said he would like the game to be low-scoring but realizes other teams have been unsuccessful in keeping games that way against OSU.“I’m not a great fan of getting in shootouts any time,” Ferentz said. “I mean if we had a lopsided lead, that’d be OK, I wouldn’t mind that, but not many teams have done that to Ohio State in recent history. Trying to contain their offense, that’s going to be quite a challenge.”Linsley said it will be important for the OSU offense, who has outscored its opponents 126 to 28 in the first quarter this season, to control the tempo of the game from the beginning.“We’ve got to score right off the bat, and then after that, we got to manage the clock by running the football,” Linsley said.While OSU is trying to end Iowa’s six-game streak of not allowing a rushing touchdown, the Hawkeyes will be trying to end a streak that dates back to the start of the 2012 season. The Buckeyes have won all 18 of its games with Meyer as coach, and hold the nation’s longest winning streak.“They’re approaching 20 straight wins and you don’t do that by accident,” Ferentz said. “It takes more than just having good players … they’ve been very, very consistent. If you look at the rate they’re scoring points and they’re moving the football, that doesn’t happen by accident either.”Part of the challenge in Iowa’s effort to end OSU’s win streak will be the Buckeye defense, which ranks 15th nationally with an average of 326.2 yards allowed per game and 24th in the FBS with 19.2 points allowed per game.“We look across, we see a team that’s very, very talented,” Ferentz said. “That includes their defense. They got phenomenally gifted athletes on the back end, I think they’re playing well and certainly that’s the case with the guys up front too … it’s hard to find a weak spot on their football team.”Iowa’s rushing attack is led by junior Mark Weisman, who has rushed for 624 yards and three touchdowns on 126 attempts this season, and ranks 32nd nationally in yards per game. Weisman said that going against the Buckeye defense is going to be tough.“They have a great defensive line, great linebackers, good secondary,” Weisman said. “They’ve pretty much stopped every rushing attack this year, so it’s going to be a real tough challenge for us.”Another challenge OSU could present to Iowa is the environment of Ohio Stadium, where Saturday’s game is scheduled to be played at 3:30 p.m.“The ‘Shoe is just by nature, it’s one of the tighter, louder places I think in our conference,” Ferentz said. “We’ve been on the road a couple times this year … but we haven’t been in an environment like the one we’re going to be in Saturday and against an opponent like this, so that’s going to be another degree of difficulty.”If the Buckeyes extend their win streak to 19 games Saturday, they would tie the 2002-03 Buckeyes for the second-longest winning streak in school history.

OSU placed 6th on the first day of play and 5th after the second round.Credit: Lantern file photoThe Ohio State field hockey team could not pull out a victory over its opening weekend, but some players said they are still full of confidence heading into Friday’s scheduled face-off with Miami (Ohio).“I think we’re all determined to come out hard after this (last) weekend,” junior forward Peanut Johnson said. “I have a sour taste in my mouth after this weekend so I’m definitely going to come out hard.”The Buckeyes (0-2) are looking to bounce back after being shutout, 4-0, by the Albany Great Danes on Monday afternoon.Much of the team’s woes may have come from a lack of posession. In all, the Buckeyes were outshot 58-14 in their first two matchups against Syracuse and Albany.“We’re able to complete a couple passes,” coach Anne Wilkinson said. “But then we’re having a rough time stringing longer passes together.”The Buckeyes may have to improve their offensive efficiency to help keep pressure off freshman goalkeeper Liz Tamburro. The Phoenixville, Pa., native made 25 saves in her first two collegiate starts.Tamburro’s 14 saves Monday against Albany were the most in a single game by a Buckeye since 2003.OSU has been focused on sustaining a constant attack in recent practices, Wilkinson said.“When we get it up there we’re very good at executing and finishing,” she said.The Redhawks (0-2) are also set to come into Columbus Friday in search of their first win after falling to Syracuse, 5-1, in the Buckeye Classic to open the season, and then losing to Northwestern at home by the same score.Miami’s senior back Ali Froede scored her 15th career goal in the loss to Northwestern on Tuesday.The Redhawks return 14 letter winners, including Froede and junior midfielder Bea Dechant. Both players earned First Team All Mid-American Conference honors last season.Defending set plays will be the key to slowing down the Redhawks’ attack, Tamburro said.“We need to start with defensive corners,” she said. “Focusing more and trying to get the ball out (of the corner).”OSU has defeated Miami in three of the last five meetings dating back to 2009, but the Redhawks have won the last two. Wilkinson said Miami’s ability to play together as a unit is what makes it so tough.“They’re a very systematic team,” Wilkinson said. “We need to be able to break them down one at a time.”Ultimately the game will come down to which team is able to possess the ball and capitalize off those possessions, Wilkinson said.“They (the Buckeyes) have really been working hard as far as finishing what they start,” she said. “Finish their passes. Finish their tackles.”OSU and the Redhawks are set to face-off at 5 p.m.
