The USA outgun Russia in the Churchill Cup

first_imgWednesday Jun 9, 2010 The USA outgun Russia in the Churchill Cup Amongst the internationals taking place around the world currently, the Churchill Cup got under way in Denver this past weekend with Canada beating Uruguay, and the USA overcoming Russia 39-22 in this featured sports betting match.The Russians looked the stronger side in the first half, but the USA got things going in the second as they stretched the lead after the scores had changed hands numerous times throughout the game.Coached by former Ireland coach Eddie OSullivan, the USA team is steadily building in stature and featured Saracens back Chris Wyles, and Biarritz winger Zee Ngwenya. Both crossed for tries as their side strung together some impressive pieces of play.“We struggled with the pace of the game early out,” said O’Sullivan. “Having not played for over six months, it was expected we’d be a bit rusty. We were happy with the win, but it’s clear we still have a lot of work going forward.“We had a proper patch in the second half, I think a lot of our guys dug deep and our replacements were fast off the bench. They all worked hard for this result.”Despite coming off second best, the Russians were equally impressive with their home grown talent and physical approach to the game, and are definitely going to be an interesting side to keep an eye on at next years World Cup, where the two sides will meet in their opening games.It was an enjoyable match and the standard of play was good to see. Russia face the England Saxons next, today, followed by France A against Uruguay. The USA Eagles will play England next on Sunday.

Syria, the Kurds and U.S. divide-and-conquer

first_imgFor the past six years, the United States, Israel, NATO and the Gulf Cooperation Council have waged an unrelenting proxy war against the sovereign, secular state of Syria. The U.S.-funded Free Syrian Army, called “moderate rebels” in the corporate-owned media, fights openly alongside forces backed by U.S. allies Saudi Arabia and Turkey. These forces, really mercenaries or contras, which include the Islamic State, Jabhat Al-Nusra (al-Qaida in Syria), Jaysh al-Islam and others, are largely constituted of foreign fighters.There is one front in this proxy war, however, that should be included in an anti-imperialist analyses. It’s the front in the north contested by the Islamic State, Turkey, U.S. imperialism and the Syrian Democratic Forces (SDF) — the last groupa mainly includes Kurdish forces.The SDF’s largest fighting force is the YPG (the Kurdish acronym for the People’s Protection Units). The YPG is allied with the Democratic Union Party (PYD), and both are allied with the Kurdish Worker’s Party (PKK). The PKK has been engaged in a decades-long fight for self-determination of the Kurdish region inside Turkish boundaries against the brutally oppressive Turkish state.In a sign of the contradictions inherent in U.S. imperialist policy toward Syria, on April 25 Turkish planes attacked units of the YPG in northern Syria, killing as many as 70 fighters. While U.S. diplomats said they raised concerns with NATO-ally Turkey regarding this strike, nothing concrete was done to stop future Turkish attacks against Kurdish fighters. (Reuters, April 25) This is one example in Washington’s long history of apparently backing one oppressed people and then turning on them.Many progressive people see the YPG, which is mostly made up of Kurdish fighters but includes other ethnic minorities as well as Western “foreign volunteers,” as representing the just struggle for Kurdish national liberation. Organized along democratic principles without a vertical chain of command, the forces of the YPG and their movement in northern Syria claim to model their “non-state” on anarchist, eco-socialist principles.The YPJ, the Women’s Protection Units, provide an active leadership role for women in their struggle.The Kurdish nationThe Kurds are a historically oppressed nation of 30 million to 35 million people. They are the world’s largest nation without a state. Most live in the contiguous, underdeveloped, mountainous region spanning four countries and speak their own language. About 14.5 million to 16 million Kurds live in Turkey, 6 million in Iran and 5 million to 6 million in Iraq. The 1.5 million to 2 million Kurds in Syria are the smallest grouping of this nation.During the Kurdish people’s fight for liberation from Turkey, Washington has supplied arms, logistical and satellite assistance, and political support for the Turkish ruling classes against the PKK, which the U.S. labels as “terrorist.” Yet in Syria, Washington has a cynical, opportunistic alliance with the YPG, using those forces to accomplish its aims of destroying the Syrian state.At times, the Syrian Democratic Forces/YPG have coordinated with the Syrian Arab Army in the fight against IS and other mercenary armies. However, SDF/YPG now operate in coordination with the U.S. military. Despite the SDF/YPG’s progressive principles and organizational structure, the Pentagon’s aim is to have it function as an effective proxy for the U.S. geopolitical goal of dismantling the Syrian state.It is not obvious what aggression the U.S. plans next for Syria after its deadly April 6 strike on the Sharyat airfield and the May 18 bombing of a Syrian government convoy. If Washington significantly steps up direct U.S. intervention, it will expect cooperation from the SDF in providing ground forces. The Pentagon has already been able to build two air bases in northeastern Syria in the past few months.Mercenaries and ‘invaders’Since at least two years ago, the U.S. has been sending special forces troops to northern Syria. As Syrian President Bashar al-Assad has stated since the U.S. sent several hundred more ground troops to Syria in the beginning of March, “All foreign troops coming to Syria without our invitation … are invaders.” Assad, who is constantly demonized in the U.S. corporate media, is the democratically elected leader of the people of Syria.The YPG has been bolstered not only by U.S. special forces but also by foreign volunteers including people from the U.S., Canada, Britain and other countries.Among them is Brace Belden, who had a Rolling Stone magazine centerfold feature on his role and inspired an upcoming Hollywood film starring Jake Gyllenhaal as the “punk florist-turned-revolutionary.” Another volunteer is Gill Rosenberg, a Canadian-Israeli woman and former soldier in the Israeli Defense Forces, and the first foreign volunteer in the Women’s Protection Units. These individuals violate Syrian sovereignty and package the  U.S. invasion of Syria as a progressive, “socialist” struggle against Islamic state fascism.Is U.S. planning to split up Syria?The Rand Corporation think tank has drawn up various “peace plans” throughout the war, detailing the U.S. and its allies’ latest plans for the partition of Syria. The most recent, dated this year, projects large swathes of Kurdish-administered territory extending about halfway to Raqqa in the south and almost to Manbij in the west, as well as a corner encompassing Azaz in northwestern Syria.Buffering these zones are “proposed international administration” zones, code words for NATO occupation and Turkish-controlled areas. Notably, these “Kurdish zones” in northeastern Syria encompass much of the country’s greatest natural wealth, including its largest oil reserves.If the U.S. aids the SDF to annex northeastern Syria, this will not lead to any meaningful form of Kurdish independence. Rather, it will mean the Kurdish forces will be subordinate to and will collaborate with the U.S., much as the Kurdish regime does inside Iraq. Meanwhile, the U.S. will destroy what remains of Syria and purge any progressive forces in the Kurdish movement.At this point, Washington sees the claims to a separate Kurdish region based out of northern Syria as fitting its goal of dividing Syria. With the Syrian state under siege, the attempt to create a Kurdish “autonomous” zone under U.S. guidance is in direct contradiction to the preservation of Syrian sovereignty in defense against imperialism. The U.S. has made this abundantly clear, saying that it plans to station its forces in Syria even once IS has been eliminated.Moreover, all of these events obscure the fact that the Syrian government and Kurdish groups have negotiated greater autonomy for the latter on their own terms before. If there is to be any change in the relationship between the Syrian state and its Kurdish inhabitants, it is clear that this change cannot be imposed by the imperialist powers. The U.S., NATO and their allies should have no say in this history.The imperialists in the U.S. and elsewhere have planned a grim end for Syria: the destruction of the sovereign secular state in favor of Balkanized ethnic enclaves in the manner of Iraq, Libya, Yugoslavia and any other state that has defied destruction and imperialist plundering since the fall of the Soviet Union. This includes the current aggression against Syria, Venezuela and the Democratic People’s Republic of Korea.There can be no genuine liberation for any peoples — Arab, Kurdish or otherwise — until imperialism is defeated in the region and the right of self-determination is fully realized and respected. Anti-war and other activists in the U.S. and NATO states must stand in full solidarity with the right of all nations to develop their collective livelihood, culture and economy without interference from imperialists.Hands off Syria! All mercenaries out of Syria! Uphold self-determination!FacebookTwitterWhatsAppEmailPrintMoreShare thisFacebookTwitterWhatsAppEmailPrintMoreShare thislast_img read more

ABUNDANCE OF SPEED SIGNED ON AS GRADE III, $100,000 MIDNIGHT LUTE STAKES ATTRACTS SPEEDY DISTINCTIV PASSION, SAN ONOFRE & FIVE OTHER OLDER SPRINTERS AT 6 ½ FURLONGS

first_imgARCADIA, Calif. (Dec. 30, 2015)–Arguably the quickest horse on the grounds, trainer Jeff Bonde’s Distinctiv Passion figures to be tested early as he defends his title in the Grade III, $100,000 Midnight Lute Stakes for older horses at 6 ½ furlongs this Saturday at Santa Anita.Idle since running a well-beaten fifth in the Grade I, six furlong Santa Anita Sprint Championship on Oct. 3, the 6-year-old Florida-bred horse by With Distinction could likely get early pressure from the likes of California-bred San Onofre, and rising star, Seattle Seranade. Distinctiv Passion has five front-running wins from nine local starts and is undefeated in two tries at 6 ½ furlongs.Owned by Edward Brown, Jr., Alan Klein and Phillip Lebherz, Distinctiv Passion will be reunited with Edwin Maldonado, who has guided him to seven of his eight career wins.   With 20 overall starts to his credit, Distinctiv Passion has earnings of $482,400.Classy eastern invader Salutos Amigos, who was fifth, beaten 4 ½ lengths by top sprinter Runhappy in the Breeders’ Cup Sprint two starts back, was finishing well when beaten 1 ½ lengths as the 3-2 favorite in the Grade III, six furlong Fall Highweight Handicap at Aqueduct Nov. 26 and would appreciate a fast pace to run at on Saturday.Conditioned by David Jacobson, Salutos Amigos, a 6-year-old Kentucky-bred gelding by Salute the Sarge, is a four-time graded stakes winner and has 10 wins from 34 overall starts. Owned by Jacobson and Southern Equine Stable, LLC, Salutos Amigos has banked a Midnight Lute-best $1,122,406.A sharp second in both the Grade III, six furlong Los Angeles Stakes and Grade II, 6 ½ furlong Kona Gold Stakes this past spring at Santa Anita, trainer Karen Headley’s San Onofre has been idle since well beaten in the Grade I, seven furlong Triple Bend Stakes here on June 27.Naturally quick, the 6-year-old California-bred gelding by Surf Cat will hope to survive what could develop into an all-out rush for the lead with Distinctiv Passion. Owned by Matson Racing, lightly raced San Onofre, who will be bidding for his first stakes win, is 9-4-4-0 with earnings of $273,040.Jerry Hollendorfer’s Seattle Serenade, who comes off a smashing 6 ¼ length allowance score going six furlongs at Los Alamitos on Dec. 11, will try stakes company for the first time as he tries to remain unbeaten in what will be his third career start. A 4-year-old Kentucky-bred colt by Smart Strike, Seattle Serenade was bred in-part by Hill ‘N’ Dale Equine Holdings.Owned by Hollendorfer, Hill ‘N’ Dale Equine Holdings, Inc., and Mark DeDominico, Seattle Serenade will break from the rail with regular rider Mike Smith.The complete field for the Grade III Midnight Lute Stakes, to be run as the sixth race on a nine-race card Saturday, with jockey and weights in post position order: Seattle Serenade, Mike Smith, 119; San Onofre, Alex Solis, 119; Distinctiv Passion, Edwin Maldonado, 121; Pulling G’s, Victor Espinoza, 119; Raised a Secret, Fernando Perez, 119; All Run, Mario Gutierrez, 119, and Salutos Amigos, Martin Garcia, 121.First post time on Saturday is at 12:30 p.m., with admission gates opening at 10:30 a.m.last_img read more

Yaya says sorry

first_imgLONDON, England (AP): Seeking to mend his relationship with manager Pep Guardiola, Manchester City midfielder Yaya Toure apologised yesterday for outbursts by his agent. A statement of contrition was demanded two months ago by Guardiola before Toure would be considered for selection again. But it’s still not clear if the four-time African Player of the Year will play again for City. “I wish to apologise – on behalf of myself and those who represent me – to the management team and all those working at the club for the misunderstandings from the past,” Toure wrote on Facebook. “Those statements do not represent my views on the club or the people who work there.” While Guardiola was receptive to Toure’s statement, the midfielder’s representative, Dimitri Seluk, had other ideas. Seluk infuriated Guardiola in September by accusing the manager of humiliating Toure by leaving him out of City’s Champions League squad. “Maybe Toure has apologised. But I don’t know for what. I think Yaya (doesn’t) mean this,” Seluk said yesterday in an interview with Talk Sport radio shortly after the 33-year-old Toure published his statement. Still, Guardiola cautiously welcomed yesterday’s apology. “We spoke this morning and, of course, it’s private,” Guardiola said. “I read what he wrote and that’s all. Of course it is good news for Manchester City. “Yaya is in all meetings and all our training sessions,” Guardiola said, shedding little light on Toure’s playing future. Toure struggled for form last season and could have trouble adapting to Guardiola’s high-energy pressing game. “I have nothing but respect for Manchester City and only wish the best for the football club,” Toure said in his apology. “I am immensely proud to have played a part in the club’s history and want to help City succeed further. I live to play football and entertain the fans.”last_img read more

41 killed at mostly Shiite college

first_imgThe blast flung blood-soaked notebooks and backpacks among the lifeless bodies and wounded. Cement walls were pockmarked by the hail of ball bearings. Parents rushed to the site and some collapsed in tears after learning their children were killed or injured.

You’re all set! Security guards at the Mustansiriyah University annex scuffled with the bomber before the blast, witnesses said. Most of the victims were students, including at least 46 injured, said police Suicide bombings by women are unusual but not unprecedented in Iraq’s chaos. The main campus at Mustansiriyah, about 1 miles away, was the target of twin car bombs and a suicide blast last month that killed 70 people. The students at the business college were returning to midterm exams after the Iraqi weekend. A 22-year-old student, Muhanad Nasir, said he saw a commotion at the gate. “Then there was an explosion. I did not feel anything for 15 minutes and when I returned to consciousness, I found myself in the hospital,” said Nasir, who was wounded in the head and chest. BAGHDAD, Iraq – A female suicide bomber triggered a ball bearing-packed charge Sunday, killing at least 41 people at a mostly Shiite college whose main gate was left littered with blood-soaked student notebooks and papers amid the bodies. Witnesses said a woman carried out the attack at the business school annex to Mustansiriyah University. Interior Ministry officials said they were still investigating those reports. The school’s main campus was hit by a string of bombings last month that killed 70 people. The political situation in Iraq was further thrown into question after President Jalal Talabani, a 73-year-old Kurd, was taken to Jordan for medical tests after feeling ill. Talabani’s son, Qubad Talabani, said his father was suffering from fatigue and exhaustion. “He did not have a heart attack” or a stroke, he told CNN. A doctor said Talabani was being treated at the heart center at King Hussein Medical City in Amman because the facility has modern equipment, not necessarily because the president suffers from a heart ailment. last_img read more

Harnessing Cellular Machines for Humans

first_imgThe cell is loaded with molecular machines, so why reinvent the wheel?  or the whole truck?  Martin G. L. van den Heuvel and Cees Dekker wrote in Science that engineers ought to put the existing technology to work.1 The biological cell is equipped with a variety of molecular machines that perform complex mechanical tasks such as cell division or intracellular transport.  One can envision employing these biological motors in artificial environments.  We review the progress that has been made in using motor proteins for powering or manipulating nanoscale components.  In particular, kinesin and myosin biomotors that move along linear biofilaments have been widely explored as active components.  Currently realized applications are merely proof-of-principle demonstrations.  Yet, the sheer availability of an entire ready-to-use toolbox of nanosized biological motors is a great opportunity that calls for exploration.It’s time to put these ready and willing workhorses to work.  Their illustration shows diagrams of ATP synthase and a bacterial flagellum, kinesin, dynein, myosin and RNA polymerase.  Of the flagellum, they said, “This powerful motor, assembled from more than 20 different proteins, is driven by an inward proton flux that is converted by several torque-generating stators into a rotary motion of the cylindrical rings and central shaft.”    They reviewed the various motors and experiments to date to harness and control them.  Some day we might use cellular motors to sort, assemble, concentrate or manufacture materials on demand.  Or, we might try to copy them from scratch with our own building blocks.  But why do that?  “The small size and force-exerting capabilities of motor proteins and the range of opportunities for specific engineering give them unique advantages over current human-made motors,” they said.  The sky is the limit; the field seems limited only by our own imaginations.  “Upon studying and using biomotors, we will gather a lot of knowledge that is of interest to biology, material science, and chemistry, and it is reasonable to expect spin-offs for medicine, sensors, electronics, or engineering,” they concluded.  “The exploration of biomotors in technology will thus remain an interdisciplinary playground for many years to come.”    Oh, one other thing.  They did make a quick comment about where these machines came from.  Here is paragraph two of their article:A huge amount of biological research in recent decades has spurred the realization that the living cell can be viewed as a miniature factory that contains a large collection of dedicated protein machines (1)2.  Consider the complicated tasks that a single cell can perform: It can create a full copy of itself in less than an hour; it can proofread and repair errors in its own DNA, sense its environment and respond to it, change its shape and morphology, and obtain energy from photosynthesis or metabolism, using principles that are similar to solar cells or batteries.  All this functionality derives from thousands of sophisticated proteins, optimized by billions of years of evolution.  At the moment, we can only dream of constructing machines of similar size that possess just a fraction of the functionality of these natural wonders.While we’re on the subject, let’s look at a cellular device that recently got more praise: the cilium.  This little rod-like projection on most cells is doing more work than previously thought.  “Appreciation is now growing for primary cilia,” said Christenson and Ott in Science,3 primary cilia being “the nonmotile counterparts, present as a single copy on the surface of most cell types in our body.”    If primary cilia don’t beat and wave like the moving kind, what do they do?  Well, for one thing, “they function as unique antenna-like structures, probing the extracellular environment for molecules that are recognized by the receptors they bear.  This sensory function allows primary cilia to coordinate numerous intercellular signaling pathways that regulate growth, survival, and differentiation of cells during embryonic development and maintenance of healthy tissues.”  New research shows that a suite of molecules move in a coordinated fashion in and out of the cilium, creating a powerful switch by which cells can turn on and off a set of signaling pathways.  That’s pretty cool for an complex antenna previously thought to be nothing more than a little bitty hair on a tiny cell.41Martin G. L. van den Heuvel and Cees Dekker, “Motor Proteins at Work for Nanotechnology,” Nature 20 July 2007: Vol. 317. no. 5836, pp. 333-336, DOI: 10.1126/science.1139570.2This reference was to Bruce Alberts’ 1998 paper that made a similar statement, calling the study of molecular machines the “biology of the future” (see 01/09/2002).3Søren Tvorup Christensen and Carolyn Marie Ott, “Cell Signaling: A Ciliary Signaling Switch,” Science, 20 July 2007: Vol. 317. no. 5836, pp. 330-331, DOI: 10.1126/science.1146180.4The ones that move are way cool: see 12/19/2005, 03/12/2001.So, “thousands of sophisticated proteins, optimized by billions of years of evolution.”  Gimme a BREAK!(Visited 37 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
